overview
Antifouling block valve used to prevent backflow pollution of drinking water pipeline safety device, is the introduction of foreign advanced technology developed by our company, safe and reliable, to prevent drinking water backflow pollution of novel valves, to ensure the health and safety of drinking water.
产品结构
安全型防污隔断阀是在两个止回阀之间加一个排水器组成排水器上
腔用高压软管与第一级止回阀进口端连接。第一二级止回阀主要由阀体、阀盖、阀瓣、密封垫、弹簧等组成。排水器主要由阀体、阀盖、隔膜、阀瓣、密封板、阀芯、阀座、弹簧等组成。
普通型防污隔断阀为两个止回阀串联而成。
Product structure
The safety antifouling block valve is composed of a drainer between two check valves
The chamber is connected to the inlet end of the first stage check valve with a high pressure hose. The first and second check valve is mainly composed of a valve body, a valve cover, a valve disc, a gasket, a spring, etc. The drainer is mainly composed of valve body, valve cover, diaphragm, valve disc, seal plate, valve core, seat, spring and so on.
The common antifouling block valve is made of two check valves in series.
工作原理
普通型防污隔断间为二个止回阀串联而成，当其中有一只封破坏时，另一只还起密封作用，防止回流。但二只止回阀密封同时破坏后，失
去了止回作用，其安全可靠性相对差些，工作原理较简单，在此不介绍。
Working principle
The common anti-fouling partition is composed of two check valves in series. When one of them is damaged, the other one also plays a sealing role to prevent backflow. But after the two check valve seals are broken at the same time, the loss
Without the check function, its safety and reliability are relatively poor, and the working principle is simple, which is not introduced here.
