Claims

[Scope of Claim for Utility Model Registration] A main valve element forming the main valve corresponds to the main valve seat provided in the main body, and a relief valve seat is provided on the pressure receiving body that forms a pressure chamber with the main body behind the main valve. In the flush valve, the pressure receiving body is provided with a relief valve that opens the main valve, and the pressure chamber is connected to the secondary side through the relief valve. A sliding member having a stepped portion protruding toward the outside and a female screw portion below the stepped portion, and a sealing member protruding upwardly and outwardly fitted onto the outer circumferential surface of the stepped portion and sliding against the circumferential surface of the pressure chamber. a first member made of synthetic resin having a small passage connecting the pressure chamber and the secondary side in the sliding part; a second member made of synthetic resin having a male screw portion and a flange portion protruding outward below the male thread, and having a female screw portion on the inner peripheral surface; and a second member made of synthetic resin above the outer peripheral surface. a third member made of metal, having a male threaded portion that is screwed into the female threaded portion of the valve seat, and a large diameter guide portion that slides on the inner circumferential surface of the main valve seat below;
An IJ valve seat made of an elastic body and clamped between the lower surface of the step of the first member and the upper end surface of the second member, and a guide of the lower flange of the second member and the third member made of an elastic body. a main valve body that is clamped between the upper end surface of the first member and a strainer that is formed in a cylindrical shape and is clamped between the sliding lower surface of the first member and the flange upper surface of the second member. - A flash valve characterized by comprising: - a ner.
