德国洛克供应进口微阻缓闭止回阀

进口微阻缓闭止回阀结构特点：

1、体形小、重量轻、结构长度只有旋启式止回阀的三分之一左右。

2、缓闭系统性能优良，不受管道中介质的影响，阀瓣先速关后缓闭，可防止破环性水锤。

3、橡胶软密封，封闭性能好，耐磨损，使用寿命长。

4、橡胶缓冲，启闭平稳，无震动，无噪音。

5、比老式止回阀流阻小，有明显的节能效果。

进口微阻缓闭止回阀描述：

德国《DE LOCKE》洛克进口微阻缓闭止回阀由阀体、阀盖、阀瓣、阀轴及调节阀等组成，安装在水泵出口处用来防止介质逆流和消除破坏性水锤，并能有效地减少阀门关闭的水锤压力，可保障管网安全运行。它具有阀瓣轻、开度大、节能，流体阻力小，水锤消除机构设计新颖，密封性能稳定可靠、耐磨损、使用寿命长、运行平稳、无震动、无噪音等特点。

Description of inlet micro resistance slow closing check valve:
The micro resistance slow closing check valve imported from German "de Locke" is composed of valve body, valve cover, valve disc, valve shaft and regulating valve. It is installed at the outlet of water pump to prevent medium reverse flow and eliminate destructive water hammer, and can effectively reduce the water hammer pressure when the valve is closed, which can ensure the safe operation of pipe network. It has the characteristics of light valve disc, large opening, remarkable power saving effect, small fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc.
