5104 Type High Performance Butterfly Valve

5104 type second-generation eccentric butterfly

valve (referred to as high-performance butterfly valve),

the valve plate and seal ring using a unique eccentric

structure, with a compact structure, good cut-off

performance, long service life and so on, with both

functions of regulating and cutting off. Widely used in

metallurgy, chemical industry, electric power, textile, food

, medicine, papermaking and other industrial sectors and

municipal engineering, waterworks and other pipelines for

tap water, sewage, oil liquids or air, gas, natural gas,

water vapor and other media to cut off or pressure, flow

control. This series of products nominal pressure levels

are 0.6. 1.0. 1.6. 2.5. 4.0MPa. Valve caliber DN50-

1200mm; to adapt to the fluid temperature range -60 ~

450 ℃; metal seal type sealing Class IV or Class V, soft

seal type for the Class VI (bubble class) or zero leakage;

flow characteristics of the approximate equal percentage.

Significant characteristics

6. This valve has large flow capacity, small flow

resistance, second only to the same diameter nonreduction O- shape ball valves.

7. This valve flow channel diameter is large, flow

channel diameter is greater than the Gb12238

specified flow channel diameter. The flow channel

barely has reduction cavity, which is convenient for

pipe cleaning and self-cleaning. More effective for

fluids that are turbid, low viscosity with suspended

particles and fibrous media.

8. Connection with pipeline adopts flangeless clamp

type. Structure length: Soft seal adopts GB12221

series (ISO5752 CN series code: 20,), hard seal

adopts GB12221 long series (ISO5752 CN series

code: 16,). Therefore, this type of valve has strong

versatility and interchangeability, and is in line with

international standards.

9. Four major categories of standard actuators:

Pneumatic piston type

Pneumatic membrane type

Electric mechanically regulating type

Electric electronically regulating type

1. High performance regulating cut-off type. It can be

used as a regulator and a cut-off valve.

2. Two-direction seal type, different from the general onedirection seal, reliable sealing even when the medium

flows backward or when \"air hammer\"

occurs.

3. Valve body adopts whole casting technology, compact

structure, small volume, light weight;

4. Using variable eccentricity structure, when closing, the

valve plate expands outward to achieve the best

peripheral sealing state; when opening, the valve plate

and the seal ring quickly disengage, effectively

preventing the seal ring from wearing out; in this way, not

only reduces the operating torque, but also increases

the valve's service life.

5. Innovative seal ring design, using the international

advanced technology; PTFE seals using \"lip-tooth\"

shape self-sealing structure; hard seal using \"U\"

shape elastic seal. The sealing structure is long-lasting

and reliable. As for the circumstances under which the

soft seal is used or hard seal is used, it is mainly

depends on the user's requirements, operating conditions

and corrosion resistance requirements.

Interchangeable.

Difference with conventional butterfly valve

5104 type high-performance butterfly valve and

conventional D671H (F, X), D971H (F, X)

difference is: conventional butterfly valve opening

moment is large, the entire opening and closing

process of the valve plate and seal ring (such as

rubber) exists \"tear\" phenomenon, resulting in

larger operation moment of conventional butterfly

valve, short service life, low sealing reliability.

While 5104 type high-performance butterfly valve

are developed for the needs of high-speed

development of automation industry, long service

life, high reliability, can be applied to high

temperature (hard seal), high pressure, high

frequency of use, it is able to regulate and cut off, it

is a kind of self-control valve which has been

covered more and more widely in recent years.

Basic structure and seal ring form

Lip and tooth seal

PFTE lip tooth-shape butterfly sealing

seat (A) flexure is closely fitted with the

outer edge of the spherical fan-shape

butterfly plate (B) to ensure reliable

sealing, the valve body (C) and inserts

(D) fasten the sealing seat in place, and

to protect it from the media, preventing

corrosion.

Eccentric principle 5104 Type eccentric butterfly valve is designed

with two eccentricities:

The rotational shaft of the valve plate is off the

center of the cross-section (a) of the sealing

surface of the valve plate; the rotational shaft is

off the center of the pipeline (b).

When opening, the points on the sealing surface

of the valve plate are separated from the seal

ring at the same time, and there is no extrusion

between the rotation of the valve plate and the

seal ring, so that the sealing surface maintains

the best sealing effect that can be adjusted

automatically by the elastic pressure of the seal

ring under pressure. With rubber and reinforced

PTFE seals, leakage class VI or even zero

leakage is achieved. Elastic metal stainless

steel seal ring for high temperatures and other

more demanding occasions
