Abstract

New Request Update 25/08/2016 The LPG valve according to this invention has been improved by providing an internal rim to the front of the section The front end of the piston is fitted with a rubber O-ring to prevent gas leakage at the front inner rim of the The front end of the piston, when the back valve moves, closes the front inner edge of the tip. Front of the piston And at the inside of the front end of the piston is a back-shaped valve A circular motion is closed on the front inner edge of the front end of the piston by gas force. In the gas tank with a high enough pressure

Disclaimer (all) which will not appear on the advertisement page. : New requests updated 25/08/2016 1. The cooking gas valve consists of a hollow valve body (1), where the upper body of the valve body (1) is a dial (2) for turning on-off the flowing gas. Into and out of the gas cylinder by turning Where the bottom part of the handwheel (2) is an external thread for fastening to the threaded inner surface of the valve body (1), where the lower center axis of the dial (2) is the axis. Transmits power (3) to move up and down within the upper body. Of the valve body (1) according to the direction of rotation of the handwheel (2) the transmission axis (3) has a long cylindrical body with a lower diameter Larger than the upper diameter Where the lower part of the transmission axis (3) is a number of grooves One is for the wear support of the rubber O-ring (4) and the bottom of the transmission shaft (3) is a plate (5) that will move up and down following the movement of the transmission rod (3) for on-off. At the gas inlet (6) of the valve body (1), where the plate (5) has a cylindrical body with a slightly tapered lower end. To be able to fit properly into the gas inlet (6) of the valve body (1). The safety valve assembly (7) is located on one side of the valve body (1) by the safety valve assembly (7) for releasing the pressure in the gas cylinder while the pressure in the gas cylinder exceeds a certain value. 8) At the bottom of the valve body (1), through the passage (8), an external surface is formed. It is an external thread for tightening the gas cylinder. The side opening (9) is on the other side of the valve body (1), with the side opening (9) having an inner surface. It is formed into an internal thread (10), the side channel (9) for the installation of a non-return valve mechanism (11), a non-return valve mechanism (11) consisting of a support socket (12) with a shaft. Hollow body with a threaded outer surface (13) for fastening to the inner thread (10) of the side channel (9), where the internal area in front of the socket (12) is the shoulder (14) at Protruding slightly inward from the front of the interior. In which the rear of the support socket (12) is a groove (15) for the support of the rubber O-ring (16) to prevent gas leakage between the surfaces. The inside of the side cavity (9) of the valve body (1) with the seat (12) and at the core of the support socket (12) is fitted to the piston (18), the locking ring (17) is inserted into the surface. Inside of the side cavity (9) of the valve body (1) to hold the part of the non-return valve mechanism (11) from falling out of the side cavity (9), the piston (18) is formed into one piece where It has the front end (19), it is a hollow cylinder whose diameter corresponds to the core size of the support socket (12), where the front end (19) of the piston (18) has a number of holes (20). Surrounding for a channel for gas to flow in Out inside the gas valve Which the rear end (21) of the piston (18) is a circular key with a size The diameter is larger than the front (19), where the outer surface surrounding the rear end (21) of the piston (18) has a number of wings (22) protruding m to support the posture of the spring rod (23), which In the position of the joint between the front end (19) and the rear end (21) of the piston (18) is a support groove (24) for supporting the insertion of the gasket (25) to prevent gas leaks. Come out Between the support socket (12) and the piston (18), characterized by the front inner rim, the front end (19) of the piston (18) is fitted with an additional rubber O-ring (26) to prevent gas leakage at The front inner edge of the front end (19) of the piston (18), when the reverse valve (27) moves, closes directly inside the front of the front end (19) of the piston (18) and the inside of the front end (19). ) Of the piston (18) is a non-return valve (27) that is The circular motion is closed on the inner edge of the front end (19) of the piston (18) by the pressure of the gas inside the cylinder that is sufficiently high.
