一种活水阀

Abstract

本实用新型涉及供水系统技术领域，公开了一种活水阀，包括主阀体、分流板、排水阀组件以及两个关断阀组件，主阀体包括主管以及与主管连通的第一支管和第二支管，主管的两端用于与外部管路连接，第一支管用于与膨胀罐连接，主管内设有进水通道和出水通道，分流板自第一支管伸入主管内并位于进水通道和出水通道之间，分流板将第一支管的内部空间分隔为与进水通道连通的进水流道以及与出水通道相连通的出水流道，两个关断阀组件设置于主管上并用于分别调节进水通道和出水通道的通断，排水阀组件设置于第二支管上并用于调节第二支管的通断。该活水阀能够将膨胀罐中的水循环起来，防止膨胀罐中出现死水，改善供水系统中水质，并且便于进行排污操作。

Claims
