[0002] A diaphragm pump is an important device commonly used for transporting various media. The liquid end cone valve core plays a crucial role inside the inlet and outlet valve boxes. During the operation of the diaphragm pump, the liquid end cone valve core moves up and down periodically as the rubber diaphragm reciprocates. This movement causes periodic impacts between the valve rubber in the valve core and the valve seat. Such impacts can lead to wear of the valve core and the valve seat, thereby affecting the sealing performance and service life of the valve.
