1
、节能：由于阀板采用 轻体结构（橡胶与金属组合结构）
，有平衡锤，局部阻

力小，开启度大。与旋启式止回阀相比，输送每千吨水可节电
15~25
度。

2
、限制、消除破坏性水锤：由于阀门关闭系统采用后段关闭阻尼机构，用延

缓关闭的方式使局部倒流的水向系统内泄流，
阀板遵循先速闭后缓闭，
从而大大降低停泵倒流 时的
水压冲击力，消除破坏性水锤峰值的产生。

3
、耐磨损、使用寿命长。 同旋启式止回阀相比，提高使用寿命
5~7
倍

4
、截流封闭性能好。逆止口与阀板之间为橡胶软密封。

5
、运行平稳、无震动、噪音低。

6
、维修费用低。与旋启式止回阀相比，降低维修费用
80%
。

二、工作原理及调试方法
Works and debugging methods
1
、本止回阀主要由阀体、阀盖、阀板组件、平衡锤、活塞组件及针型调节阀

等组成。

启动水泵时，依靠阀门进口介质的压力作用，压力水通过疏水导管进入活塞腔

内，< br>使活塞伸出并与流通介质共同推动阀板开启，
同时使活塞伸出部分预置到位，
平衡锤越过 最高
点，这样保证阀板的最大开度，使之不上下摆动。

当水流停止时
（水泵 停机）
由于阀板的自重使阀板自由下落关闭，
但由于活塞处于伸出位置顶
着阀板，使阀 板不能全部关闭，还剩下约
1/5
左右的开启间隙，这样介质可以通过，减弱了水锤峰
值压力，限制了破坏性水锤的发生。

阀板压在活塞端部，
活塞腔内的水阻碍了活塞的 快速回伸，
阻止阀板的关闭，
这时阀板在介质
的背向压力作用下，
推动活塞向 后滑移，
在活塞的推动下，
活塞里介质通过调节阀又回到了系统中，
活塞也缓慢回到原 来位置，阀板最终完全关闭。

check valve consists of valve body, valve cover, valve plate assembly, the counterweight, the piston
assembly and the needle valve and other components.
When start the pump, relying on imports of medium pressure valves, pressure water into the piston
chamber through hydrophobic catheter inside, the piston extends with the flow of the medium to jointly
promote the valve plate open, while the piston out part preset position, the counterweight over the highest
point, so to ensure maximum opening of the valve plate, so as not to swing up and down.
When the water stops (pump down) since the valve plate of the weight of the valve plate free-fall off,
but since the piston in the extended position against the valve plate, the valve plate is not fully closed,
leaving about 1/5 or so of open space This medium can be, and has reduced water hammer peak pressure,
limiting the destructive water hammer occurs.

、阀板缓闭开度的调整
slow closing valve plate to adjust the degree of opening
活塞伸出的长短，调节阀开度的大小，控制着活塞腔内的容量和阀板关闭的延

缓时间 。缓闭开度大，泄水时间长，水锤小；反之开度小，泄水时间短，水锤的形成就可能大，因
此在结构上缓 闭开度调节器，用拉杆来控制活塞的伸出长度。

开始调试时，可将活塞伸出总长（拉杆退出长 度即活塞总长）的三分之二，然后停泵，检查水
锤的大小和阀板能否关闭，水锤大，说明开度小；如果阀 板关闭太慢，说明活塞伸出太长。经调试
到理想开度后，即可用调节螺母固定拉杆，
确定活塞伸 出的长度。应该注意的是：活塞伸出的长短
的调整与供水压力，输水距离，相对高差等工况有很大关系， 它们之间是成正比例关系。另外，缓
闭时间的长短，还可用针型调节阀的开度大小来控制，这个时间可控 制在
0~60
秒，或者更长些。

otherwise the opening is small, discharge time is short, it is possible to form a water hammer large , so the

Start debugging , you can extend two-thirds of the total length of the piston ( ie piston rod length to
exit the total length ) , and then stop the pump, check the size of the water hammer and the valve plate can

piston out too long. After commissioning the ideal degree of opening , the lever can be fixed by adjusting
the nut , determine the length of the piston out . It should be noted that: the length of the piston out of
