TH1234C3 - The device prevents overfilling of gas. - Google Patents

Abstract

An over-filling gas protection device built into the gas tank has a hollow cylindrical housing. Where the top end of the house is fitted to the body part The bottom of the cooking gas valve and the lower end of the housing fit into the first body of the float. At the top of the thread there are a number of holes around it to serve as a channel for gas to flow into and out of the gas cylinder and inside the housing where the piston is located. Which at the bottom end of the case is attached to the body The first part of the float Where inside the top part of the body, the first part of the float has a push pad Is covered and at the bottom of the pedal is a push rod with a wire attached to the body. A float so that it can be inserted and push the lever up and down. And at the bottom of the body The first part of the float fits the top of the body, the second section of the float with the bottom. The second part of the float is a float.

Claims (3)

1. The over-filling gas protection device consists of a hollow cylindrical housing (1). Where the top end will be an external thread To be worn on the lower body of the cooking gas valve. And the bottom end is an internal thread To fit on the first body part of the float (12), which in the upper body of the body (2) in the address area At the bottom of the top threaded end there are a number of (4) holes around it to provide a way for the gas. Flow in - out of the gas tank The first part of the float (12) that is attached to the lower end of the body (1), the center of the body part of the float (12) is hollow. Where at the bottom of the body The first part of the float (12) will be the leg (21) to be worn on the top of the body, the second part of the float (20), the second part of the float (20), will be the float rod (22). Where the lower part of the body The second section of the float (20) is a float (23), characterized by the fact that the inside of the housing (1) has a piston (5) inserted into the upper body of the housing (2) and on the axis. The center of the piston (5) is channel (9) to allow gas to flow inward to create pressure. Reverse happens And at the junction between channel (9) of the central area and the lower part of the channel (9) will be the shoulder (10) for the support of the spring (11) and at the inside of the top part of the first part of the float (12 ) Are covered with a push pad (14), and under the pedal (14) is equipped with a rubber O-ring (16) to prevent gas leakage At the bottom of the pusher (14) is the push rod (17), a cylindrical shape with a central channel (18), with the upper part of the channel (18) smaller than the lower part (18). So that the wire (19) attached to the body The second part of the float (20) can be inserted and pushed the push rod (17) up-down. 2. Device to prevent excessive gas filling According to claim 1, where the space between The upper part of the piston (5) and the inside of the lower part of the housing (3) is covered with a spring 6. 3. The device to prevent excessive gas filling. According to claim 1 where at the end The upper part of the piston (5) is covered with a rubber O-ring (7), and at the lower end of the piston (5) there is a rubber O-ring (8) to prevent leakage of the gas.
