The main valve of the multifunctional water pump control valve includes valve body, pressure plate and diaphragm, large valve plate, slow closing valve plate, valve seat, valve stem assembly and other components. The valve stem assembly of the slow closing valve plate is connected with the pressure plate and the diaphragm. The diaphragm is compressed between the valve cover and the diaphragm seat, and the up and down movement of the diaphragm drives the slow closing valve plate up and down. The valve stem passes through the central hole of the large valve plate, so the large valve plate can slide along the valve stem within a certain range.
The movement and position of the large valve plate and the slow-closing valve plate in the main valve of the multifunctional water pump control valve determine the change of the valve working state and the opening and closing of the valve. The external fittings and pipelines of the valve transmit the pressure changes before and after the valve to the upper cavity and the lower cavity divided by the diaphragm at any time to control the movement of the large valve plate and the slow closing valve plate. The external accessories of the multifunctional water pump control valve are installed on both sides of the valve diaphragm and the inlet and outlet pipes of the valve. The lower cavity of the diaphragm and the connecting pipe on the inlet side of the valve are equipped with a control valve, a filter and a special check valve.
When we all operate and use the multifunctional water pump control valve, we should all understand the structure of our valve clearly, and operate and use our valve correctly.
