YQ98004过滤活塞式缓闭止回阀是安装在自来水厂及高层建筑给水系统,以及其它给水系统的水泵出口管道上,防止介质倒流,防止水锤及水击现象的产生。一阀兼具电动阀,逆止阀和水锤消除器,可以有效地提高供水系统的安全可靠性。我们公司生产YQ98004过滤活塞式止回阀平稳可靠,消除压力余波。

Working Principle

YQ98004型过滤活塞式缓闭止回阀安装在高层建筑、消防给水系统以及其它给水系统的管道上。当水泵开启时,水通过导管进入中腔,推动活塞上升,主阀开关。当水泵停止工作时,活塞在回水压力下降,由于进口处针形阀比出口球阀流量小,因此活塞缓慢下降,主阀也随之缓慢关闭。

Performance Features

  • 消除水锤效果好。将缓开、速闭消除水锤的技术原理一体化,防止开泵水锤和停泵水锤的产生。
  • 操作方便。只需操作水泵电机启闭按扭,阀门即按照水泵操作规程实现自动开闭。
  • 节能效果好。阀体采用了全通道流线型直流式设计,压力损失小、流量大、具体积小、重量轻。

Application Areas

YQ98004型过滤活塞式缓闭止回阀主要安装在取水、送水、加压、潜水、污水等泵站的水泵出水管道上。
