HH44X 微阻缓闭止回阀概述: I. Overview of HH44X Micro-resistance Slow-closing Check Valve:
微阻缓闭止回阀 于给排水管道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水锤压力可保障管网安全运行。 HH44X micro-resistance slow-closing check valve is installed in the water supply and drainage pipeline at the outlet of the pump to prevent backflow of the medium and eliminate destructive water hammer, and can effectively reduce the pressure of the valve closing water hammer to ensure the safe operation of the pipe network. The valve has a light disc, a large opening degree, a significant power saving effect, and a small fluid resistance.   The new design of water hammer elimination mechanism has the characteristics of stable and reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc.
