TH5644C3 - LPG valve with anti-reverse mechanism and regulate the gas distribution rate - Google Patents

Abstract

DC60 LPG gas valve with anti-return mechanism and gas flow control with valve body, at the top of the valve body is a dial used to turn on-off the gas flowing into the gas cylinder by At the bottom center of the dial is the transmission axis that will move up and down within the body. The upper part of the valve body according to the internal rotation direction of the handwheel. And at the bottom of the transmission axis Power is a disc that moves up-down according to the movement of the transmission axis to open-close the channel. Gas inlet-outlet of the gas cylinder Which on one side of the valve body is a compartment for use as a A safety valve assembly is installed to release the pressure in the gas cylinder while the pressure in the gas cylinder exceeds the limit, with the side in the opposite direction of the cavity to serve as the valve mechanism. The gas inlet and the threaded bottom surface of the gas inlet are attached to the section. Threaded top end of the upper gas pipeline Which the lower end is the thread of the delivery pipe The upper gas is attached to the flue gas valve anti-reverse mechanism and regulates the gas supply rate by the surrounding space between the gas inlet and the gas pipeline. The upper part is a degassing channel, which is used as a path to release the pressure in the gas cylinder. In the gas tank, there is an excess value to flow out to the safety valve assembly. The cooking gas valve with a mechanism to prevent reverse exit and control the gas supply rate with the valve body.At the top of the valve body is a rotary lever used to turn on-off the gas flowing into the gas cylinder. The central axis below the handwheel is the transmission axis that will move up-down within the body. The upper part of the valve body according to the internal rotation direction of the handwheel. And at the bottom of the transmission axis Power is a disc that moves up-down according to the movement of the transmission axis to open-close the channel. Gas inlet-outlet of the gas cylinder Which on one side of the valve body is a compartment for use as a A safety valve assembly is installed to release the pressure in the gas cylinder while the pressure in the gas cylinder exceeds the limit, with the side in the opposite direction of the cavity to serve as the valve mechanism. The gas inlet and the threaded bottom surface of the gas inlet are attached to the section. Threaded top end of the upper gas pipeline Which the lower end is the thread of the delivery pipe The upper gas is attached to the flue gas valve anti-reverse mechanism and regulates the gas supply rate by the surrounding space between the gas inlet and the gas pipeline. The upper part is a degassing channel, which is used as a path to release the pressure in the gas cylinder. In the gas tank there is more than a certain value to flow out to the safety valve assembly.

Claims (1)

1. The LPG valve with a mechanism to prevent the return and regulate the gas distribution rate consists of a hollow valve body (1), with the top of the valve body (1) being a key. Hand crank (2) used to open-close the gas that flows into the gas cylinder. The lower center axis of the dial (2) is the transmission axis (4) to move up-down the upper body (5) 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 (4) is a number of grooves (6) for the O-ring support (7), and at the bottom of the transmission shaft (4) is a disc. (9) To move up-down according to the movement of the transmission rod (4) to open-close at the gas inlet-outlet (10) of the gas cylinder, the safety valve (13) to act to release the pressure in Gas cylinder, while the pressure in the gas cylinder is Exceeded The safety valve assembly (13) is located inside cavity (12) on one side of the valve body (1) and the gas flow control mechanism 32, which is attached to the upper gas line (31). ) Mounted onto the threaded bottom surface of the gas inlet (10) by the gas flow control mechanism (32) consists of a mounting socket (33), which has a shape The decoy where the area The upper inside of the mounting socket (33) has a thread inside surface for fastening to the end. The bottom end is an external thread of the upper gas supply line (31), where the central area in The horizontal of the mounting socket (33) is the inner shoulder (34), and in the lower inner area of the mounting socket (33) there is a threaded internal surface for attachment to the cylinder rod (35), which The cylinder rod (35) is a hollow cylinder where the upper outer area of the cylinder rod (35) has a threaded internal surface for fastening to the lower inner area that is the internal thread of the mounting socket. (33) where the area between the mounting socket (33) and the cylinder rod (35) is where the spring (36) and the gas feed control valve (37) are installed, which the gas distribution valve (37). The gas flow control valve (37) is worn inside the spring (36) by the vertical shaft as a gas vent (38). The gas flows out through the gas vent (38) to prevent Excessive gas exits and at the outer lower part of the cylinder rod (35) is attached to the gas suction hose (41) where the contact surface is between the cylinder core (35) and the suction hose. Gas (41) is worn with an O-ring (40) to prevent gas leaks. And outside, at the upper end of the gas suction hose (41), it is covered with a casing (39).
