一、进口静音止回阀概述

进口静音止回阀Silent check valve，内部流道采用流线型设计，压力损失极小，阀瓣启闭行程很短，停泵时可快速关闭，防止巨大的水锤声，形成静音效果。适用于给、排水、消防、暖通系统，可安装于水泵出口处，以防止介质倒流及水锤对泵的损坏。

Silent check valve, with streamlined internal flow channel design, has minimal pressure loss and short valve disc opening and closing stroke. It can be quickly closed when stopping the pump, preventing huge water hammer sound and creating a silent effect. Suitable for water supply, drainage, fire protection, and HVAC systems, it can be installed at the outlet of the water pump to prevent medium backflow and water hammer damage to the pump.
