1、阀⻔控制原理，采⽤⽔⼒⾃驱动，设计了差动式结构，利⽤⽔⼒⾃⾝的能量驱动阀⻔动作，调节功能的实现，只需要控制驱动差动部件的⽔进出的量

即可。

2、通过上、下游通道⾼频电磁阀的跳动次数来精准控制进出⽔流量，该流量在差动部件即活塞腔体内部转换为腔体体积变化，该体积变化对应阀⻔开度

变化，通过这样的控制⽅式，将调节阀的调节特性由连续型改为离散型，将模拟量变成数字量。

3、控制模块通过压⼒传感仪、位移传感仪对阀⻔上下游压⼒、阀⻔开度⾏程进⾏实时监测，同时接⼊输⽔系统其他节点位置发送的实时流量、压⼒信

号，对阀⻔流量系数进⾏实时演算，对阀⻔执⾏的调节参数进⾏⾃主优化，可实现DMA分区⾃主压⼒管理。

4、阀⻔⾃带⽔⼒发电系统，在阀⻔节流件部位，采集⽔⼒能，收集⾄蓄电装置，对阀⻔⾃⾝的弱电系统进⾏供电，⽆需外部电源供电，具有环保节能、

集成控制、降低噪⾳等特点。

产品特点 Features

1.The valve control principle adopts hydraulic self drive, and a differential structure is designed. The energy of hydraulic power is used to drive the valve action, and the adjustment function is achieved by

controlling the amount of water entering and exiting the differential components.

2.Accurately control the inlet and outlet water flow rate through the jumping frequency of high-frequency electromagnetic valves in the upstream and downstream channels. This flow rate is converted into a

volume change in the piston chamber, which corresponds to the valve opening change. Through this control method, the regulating characteristics of the regulating valve are changed from continuous to discrete,

and the analog quantity is converted into digital quantity.

3.The control module monitors the upstream and downstream pressure of the valve and the opening stroke of the valve in real time through the pressure sensor and displacement sensor. At the same time, it

accesses the real-time flow and pressure signals sent by other nodes of the water conveyance system, calculates the flow coefficient of the valve in real time, and optimizes the adjustment parameters of the valve

independently, which can achieve independent Stress management in DMA zones.

4.The valve comes with a hydraulic power generation system, which collects hydraulic energy at the throttle part of the valve and collects it to the power storage device to supply power to the weak current system

of the valve itself, without the need for external power supply. It has the characteristics of environmental protection, energy conservation, integrated control, and noise reduction.

status of pipelines cannot be remotely monitored. Once an accident occurs, it cannot be detected in a timely manner, nor

can it be quickly handled. Our company provides wind solar complementary power supply technology to address the issue

of pipelines without grid coverage. For the problem of remote monitoring, if there is a network signal, it can be solved

through network signal. If there is no network signal, we provide LoRaWAN wireless remote transmission and control

technology.

WATER HAMMER RELIEF VALVE

产品概述 Product overview

技术参数 Technical parameters

The water hammer relief valve is used on the outlet pipeline of the water pump, close to the sources of water hammer such

as check valves and overpressure points in the water transmission pipeline. It is externally connected with a T-shaped tee.

When the pressure rises to the set value SRV, it can unconditionally release the high-pressure water hammer. It is a safety

protection device for the pump station and an effective means to reduce the valve closing water hammer, which can

effectively improve the safety and reliability of the system.

产品特点 Features

a、Quick response to eliminate destructive water hammer. The highly sensitive pilot valve quickly responds to overpressure conditions by opening the main valve to release water

b、Once the system pressure subsides below the set value of the pilot valve, slowly close the valve at an adjustable speed

c、Even under low working pressure, the unique differential piston design can provide reliable working power, ensuring that the valve automatically closes when the pressure returns to normal

d、Smooth operation, vibration free, and long stroke V-shaped opening enable the valve to have linear adjustment characteristics throughout the full flow range

e、Water hammer relief valves usually discharge to the air and are prone to high flow rate and cavitation when opened each time. The design of water hammer relief valves can protect the valve seat from cavitation

and high flow rate damage

f、Diversified installation, available in both right angle and straight through valve bodies, which can be installed in any direction for convenient pipeline layout

g、Reliable performance, easy to maintain, and can be maintained online

h、With an opening display, the indicator bar displays the opening of the main valve at a glance

i、Each valve has undergone factory testing and the pilot valve is set to the specified relief pressure (usually 10% higher than the normal maximum pressure of the system). The setting of the pilot valve can also be

adjusted on-site

产品特点 Features

a、High speed, large amount of exhaust: Adopting a full size outlet and inlet with maximum exhaust and suction efficiency. When the pipeline starts to enter water, it can quickly discharge the gas from the pipeline.

Timely replenish air when negative pressure occurs in the pipeline

b、Micro exhaust: When the pipe is filled with water, the main float will rise and float, sealing the main exhaust port. The small amount of gas generated during operation will be discharged through micro exhaust to

avoid gas accumulation in the pipeline

c、The micro exhaust valve adopts a roller shutter sealing structure, with sensitive actions to quickly remove accumulated small amounts of gas and can be quickly sealed

d、Quick suction: When the water flow in the pipeline is interrupted or negative pressure is generated, the floating ball will fall. Open the main exhaust port and quickly suck in air to protect the pipeline from

damage

e、Both the exhaust valve and micro exhaust valve can automatically exhaust and seal, eliminating the safety hazards of manual operation. When multiple sections of gas or airbags appear in the pipeline, not only

can the first section of gas or airbags be discharged at high speed, but also multiple sections of gas or airbags can be discharged at high speed, in a timely and continuous manner

f、The sealing of the large exhaust hole is achieved by contacting the metal floating ball with the rubber sealing seat, using a double line sealing form. The metal floating ball first contacts the sealing seat to form a

first line seal. When the pressure reaches a certain level, the floating ball will contact the inclined surface of the sealing seat to form a second line seal, ensuring that the sealing is tight

in fluid transportation pipelines, it can be controlled by adjusting the valve

opening to control the scheduling and distribution of pipeline medium, and

can be applied to various fluid systems

This series of valves is applicable to the water supply Plumbing for regulating flow, pressure, sealing and emptying. This valve can be

adjusted within the full flow range and has strong universality. It can serve as a cut-off and sealing function. It has the characteristics of

low noise, no cavitation, flexible opening and closing operation, uniform flow resistance variation, and longer service life compared to

general butterfly valves and other alternative flow regulating valves.

Size：DN200~DN2400mm

Pressure rating：PN1.0~4.0MPa

Medium:Water

Temperature:0~80℃

Operation：Gear, electric actuator

产品特点 Features

a、The valve body of a piston valve is divided into inner and outer layers, and the medium flows through the valve chamber between the inner and outer layers of the valve body. When the valve moves, the electric

actuator receives a standard signal for action and drives the valve shaft to rotate through a gearbox. The valve shaft, through a crank mechanism, drives the valve plug in the valve chamber to move forward and

backward along the pipeline axis, changing the flow channel area, and achieving the purpose of flow or pressure regulation.

b、The flow channel inside the piston valve is axisymmetric to avoid turbulence when the fluid passes through. The change in flow channel area is achieved by the reciprocating linear movement of the internal

piston along the valve axis. Regardless of the piston's position, the flow section in the valve chamber is always circular, and the water flow converges towards the axis at the outlet to avoid damage to the valve and

pipeline caused by possible cavitation caused by throttling.

c、The opening of the piston valve is linearly related to the flow rate, avoiding sudden changes in pressure or flow during the adjustment process.

d、The outlet form of the piston valve fully considers that the flow surface is not easily blocked, to ensure that the valve can be reliably adjusted according to the design flow rate when the upstream pressure

changes, and there will be no cavitation.

e、To ensure that the piston is reliably guided and slides without tilting or poor movement, a guide rail is installed within the piston stroke, and the guide rail material is made of alloy copper overlay welding, which

can ensure good lubrication and guidance performance.

f、Double sealing of metal to metal and metal to rubber ensures zero leakage.

g、The piston valve drive shaft ensures uniform force transmission, achieving valve action under high flow or high pressure differential with small operating force. Through pressure balance driving, it avoids

possible torque caused by asynchronous driving.

h、Reliable valve control: Based on the pressure and flow signals before and after the valve. Automatically adjust (or remotely control) the opening of the valve to ensure the flow and pressure settings after the

valve.

产品特点 Features

The soft sealing gate valve compensates for the elastic deformation caused by the overall sealing of the gate plate, achieving a good

sealing effect, overcoming the phenomena of poor sealing, water leakage, and rust in traditional gate valves. Low driving torque, easy

and fast operation. Widely used for cutting off medium flow in fluid pipelines such as tap water, sewage, construction, petroleum,

chemical, metallurgical, and electric power.

多⽤于市政⾃来⽔管⽹，⽤于管道检修。

Mostly used in municipal water supply networks for pipeline maintenance

a、Flat bottom type: Traditional gate valves with valve seats often accumulate in the valve bottom grooves due to external objects such as stones, wooden blocks, cement, paper scraps, and debris after flushing the

pipes with water. It is easy to cause water leakage due to the inability to close tightly. The lower part of the soft sealing gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause

debris accumulation and makes the fluid unobstructed

b、Overall rubber coating: The valve plate is made of high-quality rubber for overall internal and external sealing. Domestic first-class rubber vulcanization technology ensures accurate geometric dimensions of

the vulcanized valve plate, and the rubber is firmly connected to the ductile iron gate plate, which is not easy to fall off and has good elastic memory

c、Corrosion resistance: The valve body is coated with powder epoxy resin, which can prevent corrosion and rusting of the valve body and can be used in sewage systems. Due to the use of three \"0\" ring sealing

designs on the valve stem, the three \"O\" ring sealing rings can reduce friction resistance during switching and significantly reduce water leakage.

d、Helpful for drinking: Due to the non-toxic epoxy resin coating inside the valve body, the inner and outer surfaces of the gate are completely covered with rubber without rust or corrosion, making it suitable for

drinking

e、Online replacement of valve shaft sealing rings: Under normal water supply without interruption, valve shaft sealing components can be repaired and replaced

Nominal diameter: DN50~DN2000mm

Nominal pressure: PN0.6~4.0MPa

Medium used: water, sewage, steam, slurry, granular media, etc

Operating temperature: 0~80℃

Drive mode: worm gear transmission, pneumatic transmission, electric transmission, hydraulic transmission

Design standards:

Design and Manufacturing Standard GB/T26146 \"Eccentric Half Ball Valve\"

Flange connection standard GB/T17241.6 \"Integral cast iron flanges\"

Structural length standard GB/T12221 \"Structural length of metal valves”

Testing and Inspection Standard GB/T13927 \"Pressure Testing of Industrial Valves\"

a、Adopting an eccentric structure, during the closing process of the valve, the ball gradually approaches the valve seat and fully contacts the closed position; When the ball is opened, it completely disengages

when it leaves the sealing position. The opening torque is small, and there is no friction when opening or closing, ensuring that the valve seat and ball crown do not rub against each other during the opening or

closing process.

b、The automatic compensation sealing is reliable, utilizing the principle of eccentricity. The sealing surface is frictionless for opening and closing, and the ball and valve seat become tighter as they close. When the

sealing pair is found to be worn out for a long time, it is only necessary to adjust the bolts on the worm gear to achieve a new sealing effect even if the sealing pair is worn to a certain extent, achieving reliable

sealing and extending service life.

c、Top mounted and side mounted: The top mounted structure allows the valve disc to be installed from the top of the valve. During maintenance, only the valve cover needs to be opened and the valve disc can be

lifted out for maintenance, without the need to remove the entire valve from the pipeline. The side mounted structure is compact and suitable for occasions where valve installation space is required.

d、Self cleaning and shear structure of the sealing surface: When the ball leaves the valve seat, the medium can wash away the accumulated substances on the sealing surface. For easily crystallized medium or

debris, the ball can remove the medium crystallization or cut off debris during the closing process to achieve sealing purposes, avoiding the drawbacks of other valves being unable to open and close.

e、Tight sealing, using two layers of metal and non-metal seals. The ball and valve seat are bimetallic and adopt different processes. The sealing surface can be combined into various types such as anti-corrosion

and wear-resistant. The non-metallic seal uses wear-resistant and cold resistant rubber, and the valve seat has a guiding effect to meet the needs of different working conditions. The seal is spherical contact,

achieving zero leakage through two-dimensional eccentricity; The sealing test shall be carried out according to the national standard GB/T13927.

f、CNC machining: The metal sealing surface adopts advanced CNC machining technology, and the sealing surface is grinded separately with grinding tools to improve the surface roughness of the sealing surface

and ensure the sealing effect of the valve.

g、Large diameter valves above DN600 are equipped with support seats to facilitate the fixation of anchor bolts on the foundation, ensuring that the valve does not vibrate at high flow rates. And set up lifting rings

for easy installation and maintenance.

Testing and Inspection Standard GB/T 13927 \"Pressure Testing of Industrial Valves\"

The top cover eccentric hemisphere valve has all the advantages of the top mounted eccentric hemisphere valve, and also has the following advantages:

a、Flat bottom, no debris accumulation, and the shaft seal is protected. The top mounted eccentric hemisphere valve has a vertical shaft structure, with a deep groove at the bottom similar to a hard sealed gate

valve, which is easy to accumulate solid waste and the shaft seal is easily damaged. The upper cover type eccentric hemisphere valve is a horizontal axis structure, and the ball crown is located at the upper part of the

valve body when opened, so the bottom is flat, and impurities in the water can be smoothly carried away by the water flow without any entanglement or accumulation.

b、Horizontal valve shaft, without displacement. The traditional vertical axis structure has downward gravity, and once it shifts, the sealing will be affected, resulting in leakage. The upper cover eccentric

hemisphere valve has a horizontal axis structure, and the valve core is supported by two support points, which will not shift.

c、Online maintenance is more convenient and effective. When performing online maintenance on top mounted eccentric hemisphere valves, the worm gear head needs to be removed, the valve cover needs to be

opened, and the valve core needs to be removed before maintenance can be carried out. There are two drawbacks: one is that the workload is large, and the maintenance of large diameter valves requires the use of

lifting equipment such as cranes; The second issue is that when the valve core is removed and reinstalled inside the valve, it cannot be guaranteed that the relative position between the ball crown and the valve seat

is appropriate, resulting in poor sealing. When maintaining the upper cover eccentric hemisphere valve online, only the valve cover needs to be opened, and the workload is very small. And when replacing the

sealing ring and ball crown, there is no need to move the valve core, and the sealing effect after replacement is very reliable.
