Abstract
The present disclosure relates to a valve seat, a sealing gasket and a pressure valve. The valve seat comprises a valve seat body. A groove used for containing the sealing gasket is arranged on the valve seat body. At least one side of the groove is sunken inwards into an inclined groove shape. The valve seat with the design can prevent the sealing gasket from being damaged under a high pressure, thereby avoiding poor sealing performance; meanwhile, the valve seat is convenient to be machined and low in cost.
