      Application of check valve in the sewage in the elevator

           Sewage lifter is will not by gravity flow high pressure generated by the pump of drag away the water pumped out and applied in the basement of a building. Basement sewage through the drainage tube is pumped to a layer or is near the sewage pipe flowed away, but to upgrade sewage stop also part of the drainage tube after operation of sewage without pressure began to return because of the sewage pipe is vertical to, have a return of the enormous pressure, if the sewage directly into the device, is likely to damage to the device. The solution to the problem is to install the check valve in the drain pipe.
           Check valve is to rely on the media itself flow and automatic opening and closing valve, used to prevent the media back valve, also known as the reverse valve, Dan Xiangfa, counter flow valve, and back pressure valve. Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reverse, as well as the release of the container medium. The check valve may also be used to provide a supply of the auxiliary system to which the pressure may rise above the system pressure. Check valve in the pipeline in general should be horizontal installation.
            Check valve applied to upgrade sewage, sewage can solve well the problems caused by the reflux. The function of the check valve is to allow the media to flow in one direction, to prevent reverse flow. It work automatically, in the sewage lifter out of the sewage of fluid pressure, the valve flap to open; water pump to stop sewage backflow, by the weight of the fluid pressure and the valve flap from the close of the role of the valve on the valve seat, thereby cutting off flow.
            Check valve applied to upgrade sewage, is generally installed in the sewage pipe. Zed's original configuration of the sewage pipe has been installed with check valve, customers do not need to buy the sewage raiser after also need to buy check valve installed in the drain. The drain pipe can be installed with the check valve to prevent the return of the waste water from the equipment, and can reduce the storage capacity of the equipment. Zehnder check valve adopts Germany maximum configuration check valve material, can withstand the strong pressure of the back flow impact, long service life.
