The invention relates to a pressure relief open-type electromagnetic valve, and belongs to the field of electromagnetic valves. The pressure relief open-type electromagnetic valve mainly comprises a valve body, a valve seat which is arranged below the valve body and is connected together with the valve body, a sealing gasket which is arranged between the valve body and the valve seat, and a compression spring which is arranged between the sealing gasket and the valve seat. A water inlet and a water outlet are formed in the two ends of the valve body correspondingly and further communicate witheach other through a communication opening. A valve seat cavity is formed between the sealing gasket and the valve seat. A water passing hole communicating with the water inlet and the valve seat cavity is formed in the side, close to the water inlet, of the sealing gasket. A pressure relief hole is formed in the valve seat and is further connected with a normally-closed electromagnetic device through a first channel, an
