Problems solved by technology

[0002] In the process of living at home, gas is often used for cooking. At this time, it is often necessary to connect the gas pipeline at home. The pipe is directly socketed and connected and sealed through the circular protrusion at the pipe head to increase the friction force. In use, it is affected by the gravity of the valve itself, and there is a risk of falling off. The sealing performance is also poor, which is easy to threaten the use. It is safe, the structure is not reasonable, and it is troublesome to install, and after closing the valve, it may be touched by the outside world, which will cause the valve to not close tightly enough, resulting in the possibility of gas leakage

Embodiment

[0028] see Figure 1-Figure 7 , the present invention provides a gas pipe union valve with multiple seals, its structure includes a gas pipe valve 1, a locking mechanism 2, a rotating shaft 3, and a valve stem 4, and the surface of the gas pipe valve 1 is provided with a locking mechanism 2, so The gas pipe valve 1 described above cooperates with the locking mechanism 2, the bottom end of the rotating shaft 3 is vertically inserted into the middle position of the top end of the gas pipe valve 1, and the first end of the rotating shaft 3 is provided with a valve stem 4. The rotating shaft 3 and the valve stem 4 are an integrated structure. The gas pipe valve 1 is composed of a valve body 1a, a ball valve 1b, a gas flow chamber 1c, an air guide tube 1d, a multiple sealing mechanism 1e, and a closing mechanism 1f. The valve A ball valve 1b is provided in the middle of the body 1a, the valve body 1a is matched with the ball valve 1b, the gas flow chamber 1c is provided inside the ...

Abstract

The invention discloses a gas pipe flexible connection valve with multiple seals. The valve comprises a gas pipe valve, a locking mechanism, a rotating shaft and a valve rod, the gas pipe valve consists of a valve body, a ball valve, a gas circulating cavity, a gas guide pipe, a multi-sealing mechanism and a closing mechanism, the gas pipe valve enables sealing connection between the gas pipe andthe gas guide pipe to be tighter through the multi-sealing mechanism, then the gas pipe and the gas guide pipe are installed and locked through the closing mechanism, and the installation effect on the gas pipe valve is improved. The closing mechanism conducts secondary gas sealing on the gas pipe through a sealing strip, and gas leakage is avoided. The locking mechanism can be used for limiting the valve rod when the valve rod closes fuel gas, and avoids the situation that the ball valve is opened when the valve rod is accidentally impacted, and consequently the fuel gas leaks out of the gascirculating cavity.

Description

technical field [0001] The invention relates to the field of valves, in particular to a gas pipe union valve with multiple seals. Background technique [0002] In the process of living at home, gas is often used for cooking. At this time, it is often necessary to connect the gas pipeline at home. The pipe is directly socketed and connected and sealed through the circular protrusion at the pipe head to increase the friction force. In use, it is affected by the gravity of the valve itself, and there is a risk of falling off. The sealing performance is also poor, which is easy to threaten the use. It is safe, the structure is not reasonable enough, and it is more troublesome during installation, and after closing the valve, it may be touched by the outside world, which will cause the valve to not close tightly enough, resulting in the possibility of gas leakage. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized ...
