Abstract

LPG valve according to this invention There is a valve body where the top of the valve body is the key. Hand crank used to turn on-off the gas that flows into the gas cylinder. In which the lower center axis of the dial Will be the axis that sends the power to move up and down Inside the upper body of the valve body in the direction of rotation within In the handwheel and at the bottom of the power axis is a disc that will move up-down according to the The movement of the transmission axis to open-close at the gas inlet-outlet of the gas cylinder. And at the side in Opposite the channel is a hole for the installation of the non-return valve mechanism, which consists of a hollow body support socket where the outer surface is threaded for fixing the internal surface. The thread of the cavity of the valve body And on the inside of the socket the support is fitted with a piston with one end It is a hollow cylinder and the other end will look like a larger circular key. A hollow cylindrical section with protruding wings to support the spring.

Claims (2)

1. The LPG valve consists of a valve body (1) that is molded into a hollow body. At the top of the valve body (1) is a handwheel (2) used for opening-closing. Gas flowing into the gas tank The lower center axis of the dial (2) will be the transmission axis (5) that will move up-down within the upper body (6) of the valve body (1) according to the internal rotation direction of the hand wheel. Rotate (2) where the lower part of the transmission shaft (5) will be a number of grooves (7) for the O-ring support (8), and on one side of the valve body (1) will be. Channel (12) for use as a safety valve assembly to release the pressure in the gas cylinder at the moment of force. The pressure in the gas tank is too high. The non-return valve mechanism (14) installed inside the cavity (13) of the valve body (1) with the worn piston (25) mounted on the inside of the seat support (15) by the piston (25) is Formed into one piece that has One end is a hollow cylinder (26) with a diameter corresponding to its size. The core of the socket (15) is to allow for proper fitment, provided that the hollow cylinder (26) has a number of holes (27) surrounding it to allow gas to flow. Out inside the gas valve, which the other end (28) will look like a circle with the size It is larger than a hollow cylinder (26) with a number of wings (29) extending from the end (28) of the piston (25) to support the spring (30) and at the junction between the parts. The hollow cylinder (26), the end (28) of the piston (25), is a groove (31) for supporting the gasket (24) to prevent gas from escaping between the support socket (15) and the groove. (25) It is characterized by a plate (9) that moves up-down according to the movement of the transmission axis (5) to turn on-off at Gas inlet (10) of the gas cylinder by the plate (9) has a cylindrical body with a side end. The bottom is slightly tapered inward so that it can fit into the gas inlet (10) of the gas cylinder. And able to move up and down within the upper body (6) of the valve body (1) more flexibly, as well as allowing at the time of filling the gas can be filled faster according to the principle of moving That of air or gas dynamic (AERODYNAMICS), which at the top of the flange (9) is a button (11) inserted into the bottom cavity of the transmission rod (5) and the support socket (15) of the non-return valve mechanism (14) by the socket. Supports (15) will have a hollow body that There is a threaded outer surface (16) for attaching the threaded inner surface (17) of the slot (13), where the outer end of the support socket (15) is the shoulder (18) that protrudes forward. Slightly and in the back of the support socket (15) is a groove (21) for a rubber o-ring support (22) to prevent leakage. Of gas between the inner surface of the cavity (13) and the socket (15), where the inner end of the receptacle (15) is the shoulder support (23) as a place to support the gasket (24) to prevent gas Leaked out Between the socket (15) and the piston (25) 2.Fuel gas valve According to claim 1, at the front end of the receptacle (15) is a locking ring (19) that is inserted into the internal surface of the gas inlet (20) to secure the parts of the Non-return valve mechanism (14) prevents release of gas inlet (20).
