TH2646Y - LPG valve - Google Patents

Abstract

The liquefied petroleum gas valve described in this invention has a valve body at the top of which is a rotary knob used to open and close the gas flow into the gas cylinder. A central shaft at the bottom of the rotary knob acts as a power shaft, moving up and down within the upper part of the valve body in the direction of the rotary knob's rotation. At the bottom of this power shaft is a disc that moves up and down, following the movement of the power shaft, to open and close the gas inlet and outlet ports of the gas cylinder. On the side, opposite the opening, is a port for mounting the check valve mechanism. This mechanism consists of a hollow housing with an outer threaded surface for securing it to the inner threaded surface of the valve body. Inside the housing is a piston with one end being a hollow cylinder and the other end having a larger circular plate with protruding wings to support the spring.

Claims (2)

1. The LPG valve consists of: The valve body (1) is molded to have a hollow body, with the top of the valve body (1) being a flange. Hand crank (2) used for opening and closing the gas flow into the gas tank, with the central shaft at the bottom of the hand crank. (2) will be the power transmission shaft (5) that will move up and down inside the upper body (6) of the valve body (1) in the direction The internal rotation of the handwheel (2) where the lower part of the power transmission shaft (5) is grooved (7). A number of them are to be used as a support for the O-ring (8) and on one side of the valve body (1) will be Channel (12) for use as a mounting point for a safety valve assembly to release pressure in the gas tank when pressure The pressure in the gas cylinder exceeds the specified limit. The outlet check valve mechanism (14) is installed inside the channel (13) of the valve body (1) with the piston. (25) which is fitted onto the inside of the housing (15), the piston (25) is molded as a single piece with One end is a hollow cylinder (26) with a diameter corresponding to the size. The central axis of the support socket (15) so that it can be properly assembled together, with the shape The hollow cylinder (26) has a number of holes (27) around it to allow gas to flow in. It exits inside the gas valve for cooking, at the other end (28) it has the shape of a circular plate of size Larger than the hollow cylindrical section (26) with a number of wings (29) protruding from the end. (28) of the piston (25) to be used for supporting the spring (30) and at the joint between the cylindrical parts. The hollow end (26) of the piston (25) has a groove (31) for holding the gasket (24). To prevent gas from leaking out between the support (15) and the roller (25). Its unique characteristics include: Disc (9) that moves up and down according to the movement of the power transmission shaft (5) to open and close at The gas inlet/outlet (10) of the gas cylinder, by the disc (9), has a cylindrical body with the ends The bottom tapers slightly inward so that it can fit into the gas inlet/outlet (10) of the gas cylinder. Appropriately and able to move up and down within the upper body (6) of the valve body (1). It's more efficient and also allows for faster gas filling during the process. The principle of aerodynamic movement of air or gas (AERODYNAMICS), which is at the top of... The disc (9) will be a button (11) that is inserted into the bottom slot of the power transmission shaft (5) and The support (15) of the outlet check valve mechanism (14) has a hollow body. It has a threaded outer surface (16) for threading through the threaded inner surface (17) of the channel (13), where The outermost end of the support (15) will be a shoulder (18) that is slightly bent inward and the area The back of the socket (15) will have a groove (21) to hold the O-ring (22) to prevent leakage. of gas between the inner surface of the cavity (13) and the support (15), where the inner end of the support (15) will support (23) to serve as a place to support the gasket (24) to prevent gas from leaking out. Between the support (15) and the piston (25) 2. Cooking gas valve, according to claim 1, which at the front of the housing (15) will be a ring. A locking ring (19) is fitted into the inner surface of the gas inlet/outlet (20) to secure the parts. The outlet check valve mechanism (14) prevents the gas from escaping from the inlet-outlet channel (20).
