9、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， 阻挡阀板的关闭， 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， 活塞里介质通过调剂阀又回到了系统中， 活塞也缓慢回到原先位置，阀板最终完全关闭；1. the check valve consists of valve body, valve cover, valve plate assembly, the counterweight, the piston assembly and the needle valve and other components.When

14、ning活塞伸出的长短，调剂阀开度的大小，把握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剂器，用拉杆来把握活塞的伸出长度；开头调试时，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；假如阀板关闭太慢，说明活塞伸出太长；经调试 到理想开度后，即可用调剂螺母固定拉杆， 确定活塞伸出的长度；应当留意的是：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，仍可用针型调剂阀的开度大小来
