[0002] The gas pipeline includes control valves, filters, pressure reducing devices, pressure gauges, flow meters, online analyzers, etc., which should be concentrated in the gas inlet room. After being pressurized by blowers, compressors, pumps and boilers, the gas flows from the high-pressure part of the pipeline to the low-pressure part. It can also be transported by the gas's own pressure or gravity. When the gas needs to be transported over long distances, multiple sets of pipelines need to be connected through connecting sealing heads to form a complete transportation line.

[0003] When connecting pipelines, the connector has a complex structure, high cost, and is inconvenient to install and disassemble. After installation, the connector has limited sealing performance, which easily leads to gas leakage and waste of resources. Therefore, we propose a gas pipeline quick connection sealing head.

The surface of the shell 204 is provided with adjustment holes 205 near both sides, and the adjustment holes 205 are four groups. The inside of the shell 204 is provided with collars 201 near both sides, and the inside of the shell 204 is provided with adjacent surfaces of the collar 201. A first sealing ring 202 is embedded and installed, and second sealing rings 203 are embedded and installed on the adjacent surfaces of the first sealing ring 202 inside the housing 204. There are four groups of second sealing rings 203, and the second sealing rings 203 are semicircular. When the pipeline body 1 is embedded in the interior of the sealing head body 2, the upper and lower groups of second sealing rings 203 are tightly closed together, and the first sealing ring 202 and the second sealing ring 203 are staggered to ensure the sealing performance of the sealing head body 2; the pipeline body 1 and the sealing head body 2 are embedded and installed in the inside of the ring 201 through the pipe body 101, and the first sealing ring 202 and the second sealing ring 203 are embedded and installed in the inside of the embedding groove 102; the fixing structure 3 includes a first sleeve 301, a connecting plate 302, The support column 303, the embedded block 304, the adjusting rod 305, the U-shaped plate 306, the spring 307, and the second sleeve 308. The lower surface of the support column 303 is movably installed with a connecting plate 302. The structure of the support column 303 is similar to the overall structure of the first sleeve 301, the spring 307, and the second sleeve 308, and has a telescopic effect. The lower surface of the connecting plate 302 is located near one side and fixedly installed with the embedded block 304.

The upper surface of the second sleeve 308 is fixedly installed with a U-shaped plate 306. The U-shaped plate 306 is only installed above the second sleeve 308 in the middle position, and does not occupy much space, so it will not affect the spring 301. 07's expansion and contraction has a great impact, the surface of the second sleeve 308 is located near the upper position where the first sleeve 301 is installed, the upper surface of the U-shaped plate 306 is located on the upper surface of the first sleeve 301 and is embedded with an adjusting rod 305, and the first sleeve 301 and the second sleeve 308 are embedded with a spring 307 connected; the fixed structure 3 is located on the side away from the first sleeve 301 through the connecting plate 302 and is movably installed on one side surface of the second sealing ring 203, the support columns 303 are respectively embedded and installed in the interior of the outer shell 204 near the two sides, the adjusting rods 305 are respectively embedded and installed in the interior of the adjusting hole 205, and the first sleeve 301 is respectively embedded and installed on the inner surface of the outer shell 204 below the adjusting hole 205.

[0025] It should be noted that the utility model is a gas pipeline quick connection sealing head. When in use, the pipeline body 1 is embedded into the interior of the sealing head body 2, and the fixing structure 3 is used for fixed sealing; the pipe body 101 is embedded into the interior of the ring 201, so that the first sealing ring 202 and the second sealing ring 203 are embedded into the interior of the embedding groove 102, and the pipe body 101 is continuously pushed inward, so that the fixed joint 103 pushes the embedding block 304 to move upward, thereby shortening the support column 303, and the second sleeve 308 is embedded into the first sleeve under the action of the spring 307. Inside the tube 301, after the embedding block 304 is embedded into the fixing groove 104, the spring 307 is reset to fix the position of the fixing groove 104. Due to the pushing effect of the connecting plate 302 on the second sealing ring 203, the second sealing ring 203 is tightly attached to the inner wall of the embedding groove 102, thereby forming a seal. When disassembly is required, the adjusting rod 305 inside the adjusting hole 205 is pulled to make the second sleeve 308, the connecting plate 302, the embedding block 304, and the first sealing ring 202 move upward synchronously, thereby making the tube body 101 detach from the outer shell 204.
