& Bottom valve: The bottom valve is an energy-saving valve. It is generally installed at the bottom of the underwater suction pipe of the water pump. It restricts the return of liquid in the water pump pipe to the water source, and has the function of only entering but not exiting. There are many water inlet holes and reinforcing ribs on the bottom valve grille, which are not easy to block and prevent floating debris from entering the valve and causing the ball to be loosely sealed. In order to prevent backflow of media, check valves or foot valves should be installed on equipment, devices and pipelines. & The bottom valve is composed of a valve body, a valve cover, a valve disc, a sealing ring and a gasket. There are several types of bottom valve discs, such as single disc, double disc and multiple discs. After the bottom valve is connected to the pipeline, the liquid medium enters the valve body from the direction of the valve cover. The pressure of the liquid acts on the valve disc, causing the valve disc to open and allow the medium to flow through. When the medium pressure in the valve body changes or disappears, the valve disc Close to prevent media backflow.
