Description

Technical Field

[0001] This utility model belongs to the field of gas pipe technology, specifically relating to a multilayer oxygen-barrier conductive composite PE gas pipe. Background Technology

[0002] PE gas pipes are high-performance pipes made of polyethylene material, mainly used for transporting natural gas, liquefied petroleum gas, and manufactured gas. Manufactured through extrusion molding, they possess excellent physical properties and chemical stability, making them a replacement for traditional steel gas pipes. PE gas pipes are widely used in urban gas transmission and distribution systems as main or branch pipes to transport gas to user terminals. They offer numerous superior performance characteristics and are widely used in the gas transmission field. Compared to traditional steel and polyvinyl chloride (PVC) gas pipes, PE gas pipes are a replacement product that can completely solve the corrosion and joint leakage problems of steel and cast iron pipes, thereby ensuring the safe operation of the gas pipeline network system.

[0003] The use of a multi-layer oxygen-barrier conductive composite PE gas pipe has the following disadvantages: the connection and disassembly of traditional PE gas pipes are complicated, requiring damage to the pipe or interface. After repair, it is necessary to re-weld or replace parts, resulting in long gas outage times, affecting user use. Frequent repairs and replacements lead to increased material and labor costs, and the economic losses caused by gas outages, such as production stoppages for industrial users, are difficult to estimate. It is necessary to rely on welding, hot melting, or a large number of bolts for fixing, which takes a long time, requires high worker skills, and prolongs the construction cycle.

The first fixing sleeve 7 is snapped into the outer wall of the connecting sleeve 5, and the second fixing sleeve 8 is snapped into the outer wall of the connecting sleeve 5, and the second fixing sleeve 8 is rotatably connected to the first fixing sleeve 7.

[0029] In a specific embodiment of this utility model, the installation components allow for quick disassembly, facilitating subsequent pipeline maintenance, replacement, or upgrades without damaging the overall pipeline structure, reducing maintenance costs, minimizing gas outage time due to maintenance, and improving the reliability of gas supply. The sealing ring 6 built into the installation head, through elastic deformation or compression, tightly fits the gas pipe opening and the interface of the connecting pipe 12, forming a reliable seal to prevent gas leakage. Firstly, the protective layer 1 serves as the outermost layer of the pipeline, making it resistant to aging and wear. The conductive layer 2 and oxygen barrier layer 3 serve as intermediate layers of the pipeline for oxygen barrier and conductivity. The inner layer 4, as the layer directly in contact with the gas medium, uses corrosion-resistant materials to prevent leakage caused by internal wall corrosion. The connecting sleeve 5 connects... The four-layer structure is fixed. The connecting pipe 12 serves as the interface of the connecting pipe 12. Then, the sealing ring 6 is clamped between the connecting pipe 12 and the connecting sleeve 5. Next, the second fixing sleeve 8 is clamped on the lower outer wall of the connecting sleeve 5 and the connecting pipe 12, and the first fixing sleeve 7 can be squeezed to improve the sealing. Then, the first fixing sleeve 7 is rotated so that the first fixing sleeve 7 is also clamped on the upper outer wall of the connecting sleeve 5 and the connecting pipe 12, so that the connecting sleeve 5, the sealing ring 6 and the connecting pipe 12 are fixed together as a whole. Finally, the rotating column 9 is rotated so that the rotating column 9 is clamped in the groove of the second fixing sleeve 8. The tension of the spring 11 can pull the limiting column 10 towards the groove to limit the rotating column 9, thus realizing the quick installation of the gas pipe and other connecting pipes 12.

[0030] Specifically, a sealing ring 6 is snapped onto one side of the outer wall of the connecting sleeve 5, and the sealing ring 6 matches the connecting sleeve 5.

[0031] In a specific embodiment of this utility model, a sealing ring 6 is snapped onto one side of the outer wall of the connecting sleeve 5, and the sealing ring 6 is squeezed by the first fixing sleeve 7 and the second fixing sleeve 8 to improve the sealing performance.

[0032] Specifically, the outer wall of the first fixed sleeve 7 is rotatably provided with a rotating column 9.

[0033] In a specific embodiment of this utility model, a rotating post 9 is rotatably provided on the outer wall of the first fixing sleeve 7, and the first fixing sleeve 7 is easily fixed by engaging the rotating post 9 with the groove of the second fixing sleeve 8.

[0034] Specifically, the outer wall of the second fixed sleeve 8 is provided with a groove, which matches the rotating column 9.

[0035] In a specific embodiment of this utility model, the groove matches the rotating column 9, which allows the rotating column 9 to be better engaged inside the groove.

[0036] Specifically, a limit post 10 is slidably provided on the inner wall of the second fixed sleeve 8, and a spring 11 is provided on the outer wall of the limit post 10. The other end of the spring 11 is fixedly provided on the outer wall of the second fixed sleeve 8.

[0037] In a specific embodiment of this utility model, a limiting post 10 is slidably provided on the inner wall of the second fixing sleeve 8, which can prevent the rotating post 9 from falling out of the groove.

[0038] Specifically, the inner walls of the first fixing sleeve 7 and the second fixing sleeve 8 are fitted with connecting pipes 12.

[0039] In a specific embodiment of this utility model, the inner walls of the first fixing sleeve 7 and the second fixing sleeve 8 are fitted with a connecting pipe 12, which enables the connecting pipe 12 to be better connected and installed with the gas pipe.

[0040] Working principle: First, the protective layer 1 serves as the outermost layer of the pipeline, making it resistant to aging and wear. The conductive layer 2 and the oxygen barrier layer 3 serve as the middle layers of the pipeline for oxygen barrier and electrical conduction. The inner layer 4, which is in direct contact with the gas medium, is made of corrosion-resistant material to prevent leakage caused by internal wall corrosion. The four-layer structure is fixed by the connecting sleeve 5. The connecting pipe 12 serves as the interface of the connecting pipe 12. Then, the sealing ring 6 is clamped between the connecting pipe 12 and the connecting sleeve 5. Next, the second fixing sleeve 8 is clamped on the lower outer wall of the connecting sleeve 5 and the connecting pipe 12, and the first fixing sleeve 7 can be squeezed to improve the sealing. Then, the first fixing sleeve 7 is rotated so that it is also clamped on the upper outer wall of the connecting sleeve 5 and the connecting pipe 12, so that the connecting sleeve 5, the sealing ring 6 and the connecting pipe 12 are fixed together as a whole. Finally, the rotating column 9 is rotated so that the rotating column 9 is clamped in the groove of the second fixing sleeve 8. The tension of the spring 11 can pull the limiting column 10 towards the groove to limit the rotating column 9, thus realizing the rapid installation of the gas pipe and other connecting pipes 12.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
