Bottom valve of water pumpOverview:
should
valveIt is an energy-saving valve, usually installed at the bottom of the underwater suction pipe of the water pump limitationThe liquid inside the pipe returns to the water source, playing a role of only entering and not exiting There are many inlet products and reinforcement ribs on the valve cover, which play a role in preventing blockage and are mainly used in the pumping pipeline The role of waterways and supports Caliber types include single petal, double petal, and multi petal There are flange connections and threaded connections
Structure and principle:

This valve consists of valve estimation, valve disc, valve cover, liner, sealing ring and other parts. See the figure below for details. Water from the water source enters the valve body through the valve cover Under the pressure of the fluid, the valve disc opens the water. When the indicator stops, the pressure in the outlet pipe quickly closes the valve disc, and the liquid will not flow back to the water source, which plays a role in both smooth pumping and saving water energy loss
