Abstract

DC60 (12/10/54) Gas shield and gas flow control mechanism for the LPG valve consists of a molded body section with a hollow body for a shaped gas channel. Cylinder to use as a way for gas to flow in and out of the gas cylinder. A wear rod that is securely fastened in. With the inner surface area below the body Where the spring bar rests at the top of the body Top of the barrel wear The body is worn with a hollow cylinder that The diameter corresponds to the inner diameter of the fuselage so that it can Inserts firmly on the body part, tightly. And there is a shroud encased around the spring bar, with the sleeve being a hollow cylindrical rod for use as a gas-filled protection or Transferring gas water from the gas cylinder by using an external pressure device. Which the sheath will go to put on Attach to the outer edge of the spring bar. The mechanism to prevent gas transfer and regulate the gas supply rate of the LPG valve consists of a molded body section with a hollow body for a shaped gas channel. Cylinder to use as a way for gas to flow in and out of the gas cylinder. A wear rod that is securely fastened in. With the inner surface area below the body Where the spring bar rests at the top of the body Top of the barrel wear The third cylinder with the lower body is a hollow cylinder that The diameter corresponds to the inner diameter of the fuselage so that it can Inserts firmly on the body part, tightly. And there is a shroud encased around the spring bar, with the sleeve being a hollow cylindrical rod for use as a gas-filled protection or Transferring gas water from the gas cylinder by using an external pressure device.

Claims (4)

1. Mechanism to prevent gas transfer and control the gas supply rate of the LPG valve consists of a body (1) that is molded into a hollow body for a gas channel (2) that is a cylindrical shape for use. It is a way for gas to flow in and out of the gas cylinder. The outer body of the fuselage section (1) has been formed so that the upper part is in line with the gas burner and gas burner. And the lower part The size corresponds to the inlet of the gas cylinder. Where the outer surface, the lower part of the body (1), has an external threaded body (3) for attachment to the gas cylinder. The wear rod (8) is firmly attached to the lower inner surface of the body (1) the spring rod (13) located at the top of the upper body (10) of the rod ( 8) where the spring bar (13) is attached to the sleeve (12) of the wear rod (8) the valve stem (7) over the top of the spring bar (13), where the valve stem ( 7) A lower body (14) is a cylinder whose diameter corresponds to the inner diameter of the sleeve (12) of the wear rod (8) so that it can be inserted into the sleeve (12) of the bar. (8) can be worn, and the upper body (15) of the valve stem (7) is tapered to provide dimensions. Corresponds to the size of the valve seat (6) of the body (1) for sealing in the valve seat cavity (6), where the upper body (15) of the valve stem (7) has a seal (16). Worn attached to prevent gas leakage It is characterized by the wear rod (8) with the lower body (9) is a hollow cylinder with the size. The diameter corresponds to the inner diameter of the body part (1) so that it can insert Firmly fixed to the body part (1) The inner edge of the upper body, the lower body (9) of the wear rod (8) has a tilted edge (19) that will tilt down from the top edge. To the lateral body edge for use as a support for the gas shield (20), in which the upper body (10) of the wear rod (8) has a number of vertical ridges (11) extending. On the side Up until a gas channel is formed between the vertical ridges (11), where at the top of the body, the top (10) of the rod (8) is a sheathed sleeve (12). The shrouded hollow cylinder (17) is encircled around the spring bar (13), where the sleeve (17) is a hollow cylinder for use as a conduction mechanism against gas transfer and control. The gas supply rate of the cooking gas valve is recycled when an external pressure device (18) is used to fill the gas or drain the gas from the gas cylinder. By using an external push device (18) to press the valve stem (7), it will damage the casing (17) and cause leakage. Gas and will cause the valve stem (7) to jam so that it cannot work as well, which the sleeve (17) will attach to the outer edge of the spring bar (13). 2. Mechanisms to prevent gas transfer and regulate the gas distribution rate of the LPG valve according to claim 1, in which the interior of the upper part of the body (1) is a gasket ring (4) that has been attached. To the inner shoulder edge (5) of the body part (1) and at the bottom area the inner shoulder edge (5) of the body part (1) is the valve seat (6) as a support for the top of the Valve stem (7) 3. Mechanism to prevent gas transfer and control the gas distribution rate of the LPG valve according to claim 1 or 2, where at the bottom of the upper body (15) of the valve stem (7) is a small locking flange ( 23) The horizontal protrusion surrounding the valve stem (7) for use as an implant to the inner surface of the casing (12) of the thrust rod (8), where such an implantation of the locking flange. The small size (23) against the sleeve (12) of the thrust rod (8) causes the valve stem (7) to be held tightly to the thrust rod (8) so that the valve stem (7) cannot be moved up from the rod. The cylinder wears (8) when it is in use. External pusher (18) presses on the valve stem (7). 4. Mechanism to prevent gas transfer and control the gas distribution rate of the LPG valve according to claim 1 to 3. It is additionally equipped with a gas shield (20) installed inside the lower body (9) of the cylinder block (8), the gas shield (20) is supported by a bending ring. (21) where the bending ring (21) is embedded within the horizontal groove (22) located at the bottom of the body part (1).
