SJ300X緩閉消聲止回閥

一、結構及用途 Structure and purpose

該閥主要用於給水係統的水泵出口處,防止介質倒流,水錘及水擊現象,該閥兼具電動閥、逆止閥和水錘消除器三種功能,可有效地提高供水係統的安全可靠性,並將緩開、速閉、緩閉消除水錘的技術原理一體化,防止開泵水錘和停泵水錘的產生,隻需操作水泵電動啟閉,閥門即可按照水泵操作規程自動實現啟閉,該閥流量大,壓力損失小,密封性能可靠,安裝維護、調試檢查方便、使用壽命長。

Used on the pump outlet of a water supply system to prevent medium's back-flow.water hammer and water shock.combining three functions as an elec-tric valve,check valve and water hammer remove r,capable of effectively raisingsafety and reliability of the water supply system,integrating the technical principle of slow-open,speed valve,slow-close removing water hammer and preventing both pump-starting and pump-stopping water hammers from being formed The gate can automatically carry out open-close upon the operation rules of the water pump just by operating the pump t0 open or close electrically This valve features a big flow and a small pressure loss.reliable sealing performance,easy installation,debugging and maintenance and a long duration.
