I. Introduction of HQ44 micro-resistance ball check valve


       采用橡胶包皮球为阀瓣,在介质的作用T可在阀体内的滑道上滚动从而打开或关闭阀门。 The HQ44 micro-resistance ball check valve uses a rubber-coated ball as the disc. The role of the medium T can be rolled on the slide in the valve body to open or close the valve. Large flow rate, small flow resistance loss, good sealing performance, sound reduction can reduce water shock wave. It can be installed horizontally or vertically. 可用于冷水、热水、工业及生活污水等管网的水泵出口防止介质倒流。 Silent check valve can be used to prevent the medium from flowing backwards in the pump outlets of pipe networks such as cold water, hot water, industrial and domestic sewage.
