Anti-pollution cut-off valve, is based on its application in life named, then the anti-pollution cut off pump in the end what, what are the applications and needs attention? Anti-pollution cut-off valve: installed in various types of piping systems used to strictly prevent media backflow, to protect the media or equipment after the pollution-free anti-reverse type valve. By two series of check valves and transition parts, tight seal, to ensure that no medium backflow. Pipeline anti-fouling cut-off valve used to prevent the drinking water pipeline backflow pollution safety devices to ensure the health and safety of drinking water. Product Structure: Safety anti-fouling cut-off valve is composed of a drainage between the two check valves. Drainage on the cavity with a high pressure hose and check valve inlet side of the connection. The first and second check valve is mainly composed of the valve body, valve cover, disc, gaskets, springs and so on. Drainage mainly by the valve body, valve cover, diaphragm, disc, seal plate, valve, valve seat, spring and other components. Ordinary anti-fouling cut-off valve for the two check valves in series. How it works: Antifouling cut-off valve for the two check valves in series, when one of the seal damage, the other also play a sealing role to prevent back flow. However, the two check valve seal at the same time destroyed, it lost the role of check, its safety and reliability is relatively poor, the principle of work is simpler. Anti-fouling cut-off valve on the basis of the ordinary type plus drainage, so that even if the two check valve seal damage at the same time, it can also play a role in preventing backflow pollution.
