Abstract

The cooking gas valve with the added mechanism is a non-return valve mechanism. It will be equipped with a mechanism Non-return valve in the opposite position of the safety valve assembly. In which the anti-return valve mechanism will There is a hollow-body support socket with a threaded outer surface for attaching to a gas inlet and a hollow body part, with the outer end made on the shoulder to be closer to the inside of The support socket and the innermost end of the support socket are fitted with a single, molded piston with One end is a hollow cylinder and has a number of holes surrounding the shape. Hollow cylinder to serve as a way for gas to flow in and out of the cooking gas valve. Part at the other end It is a solid circle key larger than a hollow cylinder with long protruding wings to use. For supporting springs

Claims (1)

1. The non-return valve mechanism of the cooking gas valve consists of a support socket (9) with a hollow body with a threaded outer surface for attachment to the gas inlet (10) and at the outermost end. It will be the shoulder (11) that extends into the far end. As shown below, it is used to support the O-ring (12), the O-ring (12) installed inside the support socket (9), with the inner end designated as the surrounding protrusion (13). Rubber body of O-ring (12) for support with groove (14) located at the end. The outermost part of the body (15), the body part (15) that is inserted into the socket (9), which has a hollow body with the outer end to form the shoulder (16) so that it is closer to the inside of the socket. Supports (9) and at the end of such side (15) is a groove (14) for fitting into the protrusion (13) of the O-ring (12) at the area. The other end of the body (15) is surrounded by a number of O-rings (17). It is characterized by having a piston (18) fitted to the innermost end of the support socket (9), being molded into one piece. There are a number of holes (20) surrounding the hollow cylindrical part (19) to allow gas to flow into and out of the cooking gas valve. At the other end (21) is a larger solid round key than a hollow cylinder (19) with a number of wings (22) extending from such end (21) to It is used for supporting the spring (23) and at the junction between the hollow cylindrical part (19) and the end (21), there is a rubber O-ring (24) around it.
