⊚ 活塞式结构说明Descriptionofthepistonstructure

为了使阀盘上下产生压差，活塞的面积必须大于阀盘的面积，这样在大口径的阀门中活塞面积很大，运作平稳性较差。我们的活塞缸的底部设计了导流孔结构，适当地增加阀盘运动的阻尼，使阀盘的运动更趋于平稳，从而提高阀门的可靠性，减少故障的发生。导流孔均匀分布在活塞缸的底平面上，并视阀门口径的大小决定导流孔的数量和尺寸。

In order to cause a pressure diference between the upper and lower sides of the valve disc. the area of the piston must be larger than valve disc, so that in a large-diameter valve, the area of the piston m1 moothnes operation is poor. The bottom of our piston cylinder desig ned VItn diversion hole Str properly increase the damping of the movement of the valve disc, movement of disc more stable, thereby improving thereliability of the valve and reducing the occurrence The diversion holesareevenly distributed on the bottomplaneof the piston cylinder, and the number andsize of thediversion holesare determined accardingto the size of the valve diameter.

双重导向运动平稳 Double guidance,smoothmovement

阀体颈部有一定宽度的加工面，与不锈钢活塞缸的外圆配合，使得活塞缸在阀体内平稳固定；带有两道密封圈的活塞在经过行磨的活塞缸内壁作上下运动，同时活塞缸下端设计成带铜衬套的导向孔，形成双重导向，即使口径再大的阀门也能确保其运动自如、平稳，从而提高使用寿命和安全可靠性。

The neck of the valve body has a certain width of the processing surface, which cooperates with the outer circle of the stainless steel piston cylinder, so. that the piston cylinder is smoothly fixed in the valve body; thepiston with two seal rings moves up and down on the inner wall.of the piston cylinder after grinding,and at the same time The lower end of the piston.cylinder is designed asa guide hole with a copper bushing to form a double guide. Even a valve with a larger diameter canensureitssmoothand smoothmovement,therebyimproving servicelife and safetyand reliability.

密封垫和密封环双重密封 Seai and gasket double seal

阀盖与阀体上的内凹槽通过活塞缸的外圆定位，确保阀盘、活塞、指示杆同心，使阀盘运动自如，从而提高主阀的灵敏度，即使在流量或压力波动不大的情况下，活塞式水力控制阀亦能可靠地工作。为了达到阀体、阀盖、活塞缸连接处于外漏，在活塞缸上面与阀盖连接面和活塞缸下面与阀体连接处分别采用弹性垫片和NBR密封环密封。

The inner groove on the bonnet and valve body is positioned through the outer circle of the piston cylinder to ensure that the valvedisc, piston and indicator rod are concentric,sothat the valve disc can move freely, thereby improving the sensitivity of.the main valve, even when the flow or pressure fluctuations are not large Under the circumstances,the piston hydraulic.control valve can also work reliably. In order to achieve the leakage of the connection between the valve body. the valve cover and the piston cylinder, the connection surface between the upper surface of the piston cylinder and the valve cover and the connection between the lower surface of the piston cylinder and the valve body are respectively sealed with elastic gaskets and NBR sealing rings.

300X型缓闭止回阀由主阀、单向阀、针阀、球阀、微形过滤器和压力表组成水力控制阀接管系统。利用水力自动操作，可使主阀得到最佳的开启和关闭速度。防止水锤水击的产生，以达到缓闭消声的效果。当阀门从进口端给水时，水通过微型过滤器、针阀、单向阀进入主阀控制室，再经过球阀排水至下游。因为针阀开度小于球阀开度，即主阀控制室的排水速度大于进水速度，因此控制室压力降低，作用于主阀盘下端的进口压力打开主阀向下游供水。当管道停止供水时，若下游水开始回流，一部分回流水经球阀进入主控制室，由于单向阀作用，回流水不能从主控制室流出，引起主控制室逐渐升压，缓缓关闭主阀本产品利用水力自力控制，不需要其它装置和能源，保养简便，开启及缓闭平稳。此阀门产品广泛用于高层建筑、生活区等供水管网系统及城市供水工程。

500X泄压/持压阀由主阀、导阀、针阀、球阀、微形过滤器和压力表组成水力控制接管系统。利用水力自动操作，即可以作泄压阀用又可作持压阀用。做泄压阀用时，可维持供水路压力在设定的安全值之下，保持主阀上游供水压力。其工作原理，当导阀调整为泄压状态时，水通过针阀、主阀控制室、球阀A、导阀、球阀B流向出口，此时主阀处于开启状态。当进口压力超过导阀设定的安全值时，泄压导阀会自动开启，通过球阀C放出部分水，使管路泄压。当压力恢复到安全值时，泄压阀自动关闭，作泄压阀时，各球阀常开。当导阀常开。当导阀调整为持压状态时，只要主阀进口水压底于导阀设定值，导阀即关闭。主要控制使升压，主阀关闭。当主阀上游供水压力超过导阀排至出口，控制室将压主阀开启，开始供水，即保持了上游水压。作持压阀用时，球阀C常闭或用丝堵换下。本产品利用水力自力控制。不需要其它装置和能源，保养简便，一阀多用。广泛用于高层建筑、生活区等供水管网系统及城市供水工程。

700X水泵控制阀由主阀、电磁导阀、针阀、球阀、单向阀、行程开关、微形过滤器和压力表组成水力控制接管系统。水泵需停止工作时，先由进口压使主阀关闭90%后水泵停止运转。剩余10%由回水关闭。可预防水锤现象发生。其工作原理：当水泵工作阀门向下游供水时，点此导阀全开，针阀调至适当开度，上游水经针阀、单向阀进入主阀控制室，经电磁导阀流出，此时主阀控制室的压力保持主阀处于合适的开度，保持下游正常供水。当水泵停止工作时，电磁导阀先关闭，主阀控制室停止排水，控制室压力升高，主阀开始关闭。当关闭至90%时，主阀上部行程开关输出停泵信号，水泵停止运转。此时下游回水晶单向阀进入主阀控制室，控制室压力升高，主阀被关闭。本产品利用电磁导阀控制，不需要其他装置和能源。节约能源，保养简便，停泵平稳，广泛用于高层建筑、生活区等供水管网系统及城市供水工程。

800X压差旁通平衡阀由主阀，压差控制导阀、针阀、球阀、微形过滤器和压力表组成水力控制接管系统。通过专门设计的导阀控制室，对压力变化信号进行比较，输出主阀开度信号，控制主阀开度，从而控制主阀的进出口压差在设定值上。其工作原理是，当主阀进出口间压差变化时，接管A与接管B间压差发生变化，此变导阀的开度。压差大时导阀开度大，控制室通过C管的下泄水量增大，主阀控制室压力下降，主阀开度增大，主阀进出口间压差变小。反之，若主阀进出口间压差变小，则导阀开度变小，主阀控制室压力上升，推动主阀开度减小而使主阀压差增大。这种负反馈作用使主阀进出口间压差稳定在设定值上。设定针阀开度和导阀弹簧压力可设定主阀进出口间压差。本产品利用水力自力控制，不需要其它装置和能源，保养简便，广泛用于高层建筑、生活区等供水管网系统及城市供水工程。

900X紧急关闭阀是由主阀、针阀、导阀、压力表以及接管等其他管件组成。是一种用于消防用水与生活用水并联的供水系统中，用来调配供水方向的阀门。当火灾发生时，消防急需大量用水，900X紧急关闭阀立即切断生活用水，确保足够的消防用水；当消防停止用水压力减小时，阀门自动打开，呈常开状态，恢复生活供水。其工作原理是，当主阀进口压力低于导阀设定的压力时，导阀此时处于开通状态，主阀上盖腔内压力与主阀出口压力相等，进口与出口存在压差，水流经阀口由出口流出。当消防泵启动，或变频泵压力升高，超过导阀设定压力时，由主阀进口通向导阀控制管到主阀阀盖上腔，因阀瓣受到的向下的压力大于向上的推力，主阀关闭。值得注意的是，进口压力小于设定压力该阀一直处于开启状态，进口压力大于设定压力，该阀处于关闭状态。该阀使系统无须另设专门的消防单独供水管网，大大地节约了建设成本和用水量。该阀门控制灵敏度高，安全可靠，调试可简单，使用寿命长，用于生活小区中消防用水与生活用水并联的供水系统。

为了更有效地防止水锤的产生，第二代隔膜式水力控制阀将控制室设计成双腔体形式。根据不同的用途可以将两个腔室彼此隔离或相通，以实现缓开、缓闭或速闭等辅助功能。在一定程度上阻碍水锤的产生或功缓解水锤的力度，保护阀后的其他设备不受损坏。除此之外，阀盖与上腔室连为一体，使得阀盖、上腔室、阀杆、阀盘成为整体，只要松开阀体上的连接螺栓，即可将其一并取出，方便维修及更换易损件。

第二代隔膜式水力控制阀的阀盖、上腔室、阀杆、阀盘可整体取出，方便维修及更换橡胶密封面、O形环等易损件。阀盖与上腔室之间的隔膜采用尼龙网布加强型橡胶隔膜，耐剪切应力使用安全可靠。

第二代隔膜式水力控制阀的内件，包括上腔式、阀杆、阀盘、弹簧、螺栓等，除了不锈钢件以外都进行了无毒喷塑处理，具有良好的防锈功能。

The valve cover, upper chamber, valve stem and valve disc of the second-generation diaphragm hydrauliccontrol valve can be taken out asa whole,whichisconvenient for maintenanceand replacement of wearingparts suchas rubber sealing surfaces and O-rings.The diaphragm between the valve cover and the upper chamber adopts a nylon mesh reinforced rubber diaphragm, which is safe and reliable to use against shear stress.

Theintemalsof the second generation diaphragm hydraulic control valve, including the upper chamber, valve rod, valve disc, spring, bolt,etc.,are treated with non-toxic plastic spraying except for the stainless steel parts, which has a good anti rust function.

第二代隔膜式水力控制阀的阀盘采用间隙组合结构，即阀杆和阀盘孔之间有一定的间隙；阀盘用螺钉和挡块相对固定在阀杆之间并留有1-2毫米间隙，这样阀盘在垂直于阀杆的平面上有一定的自由度，可以弥补由于加工或装配误差造成阀座密封面与阀杆不垂直的缺陷，实现了百分之一百的零泄漏。

Thevalve disc.of the second-generationdiaphragmhydrauliccontrol valveadoptsagap combination structure, that is,there is a certain gap between the valve stem and the vaive disc hole; the valve disc is relatively fixed between the valve stem with screws and stoppers and there is 1-2 Mm gap, so that the valve disc has a certain degree of freedom on the plane perpendicular to the valve stem, which cancompensatefor the defect that the valve seat sealing surfaceis not perpendicular to thevalve stem due to processing or assembly errors, and achieves 10o% zero leakage.

软密封蝶阀概述

SoftSealingButterflyValveDescription

⊚ 产品结构及性能简介Introductionofproductstrutureandperformance

本蝶阀主要由阀体、转轴、阀板、阀座、润滑衬套、锥销、蜗轮蜗杆机构组成，靠手柄或蜗轮蜗杆机构或气动、电动执行器带动转轴及阀板旋转实现启闭和控制流量。

当关闭阀板时，手柄机构压下压把，按顺时针方向旋转90°，然后放下压把由定位盘定位（0°-90°之间有10个定位位置），达到关闭及调节流量的目的。法兰连接尺寸符合国标GB/T913、欧标DINEN1092、英标BS4504、日标JISB2220、美标ASMEB16.5、ASMEB16.47、俄标GOST12815等。其产品特点为：

>小型轻便，容易拆装及维修，并可在任意位置上安装;

>结构简单、紧凑、90°运转启闭迅速；

>操作扭矩小，省力轻巧；

>达到完全密封，气体试验泄露为零；

>选择不同零部件材质，可适用多种介质；

>流量特性趋于直线，调节性能好：

>启闭试验次数多达数万次、寿命长。

产品用途Application

适用在石油、化工、食品、医药、造纸、水电、船舶、给排水、冶炼、能源等系统管路上，可在多种腐蚀性、非腐蚀性的气体、液体、半流体以及固体粉末管和容器上作为调节和截流设备使用。

蝶阀的回转中心（即阀轴的中心）位于阀体的中心线和蝶板的密封面截面上。阀座采用合成橡胶或聚四氟乙烯。关闭时蝶板的外圆密封面挤压阀座，使阀座产生弹性变形而形成弹性力作为密封比压，保证蝶阀的密封。该阀可设计成法兰连接、对夹连接和单夹连接。阀轴可设计成通轴无销、双半轴无销和有销结构。
