Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas pipelines, in particular to a leakage-proof gas pipeline. Background Art
[0002] The gas pipe is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. Therefore, the gas pipe plays an important role in transporting gas. The gas pipe has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas blocking. The soft protective layer material on the surface of the pipe is safer, easier to clean, and more beautiful.
[0003] In gas pipelines, the interior is usually made of plastic. Specifically, when in use, the gas pipeline is installed and connected to the inside of the kitchen. However, since the use of gas will cause the kitchen to generate high temperature, and when not in use, the kitchen temperature will drop. Then, repeated temperature differences cause large temperature differences in the use environment of the gas pipe. When the pipeline is used in an area with a large temperature difference, the pipeline will cause deformation due to the temperature difference. In order to improve the protection of the pipeline, a reinforcement device will be installed on the outside of the pipeline. When the pipeline is deformed and the outside of the pipeline is subject to a restricted condition, the pipeline will cause rupture and damage due to pressure, which will lead to gas leakage. For this reason, we have proposed a leak-proof gas pipeline. Utility Model Content
[0004] In response to the shortcomings of existing leak-proof gas pipelines, the utility model provides a leak-proof gas pipeline, which is equipped with a first sealing gasket, a second sealing gasket, a gas filling tube and a second sealing gasket to seal and protect the outside of the protective layer. At the same time, when the protective layer and the inner wall of the pipeline are deformed due to temperature difference, the first sealing gasket, the second sealing gasket, the gas filling tube and the second sealing gasket provide buffering, thereby increasing the activity space of the deformed pipeline and avoiding pipeline rupture, thereby solving the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical solution: a leakage-proof gas pipeline, comprising a protective outer shell, a reinforcement sleeve fixedly connected to the outside of the protective outer shell, a first sealing gasket and a second sealing gasket installed on the inner side of the reinforcement sleeve, a gas filling tube is sequentially maintained between the first sealing gasket and the second sealing gasket, a third sealing gasket is cross-wound around the outside of the gas filling tube, a protective layer is installed on the inner side of the second sealing gasket, a reinforcement layer is installed on the inner side of the protective layer, the inner side of the reinforcement layer is adhesively mounted with the inner wall of the pipeline, a tooth groove is provided on the inner side of the inner wall of the pipeline, joints are installed at both ends of the tooth groove, an inner sleeve is installed on the inner side of the joint, and a clamping device is sleeved on the outside of one end of the joint.
[0006] Preferably, the reinforcement sleeves are semicircular in shape, and are arranged at equal intervals outside the protective shell.
[0007] Preferably, the interior of the gas filling tube is filled with nitrogen, and the gas filling tube and the third sealing gasket are both sleeved between the first sealing gasket and the second sealing gasket.
[0008] Preferably, the reinforcement layer has a mesh structure, and the reinforcement layer is arranged between the protective layer and the inner wall of the pipeline.
[0009] Preferably, the teeth grooves are arranged at equal intervals on the inner side of the inner wall of the pipe, and the teeth grooves are in a tooth-like structure.
[0010] Preferably, a thread groove is provided on the inner side of one of the two groups of joints, and a thread groove is provided on the outer side of the other group of joints. An opening is provided on the outer side of one end of the joint, and the clamping device is sleeved on the outer side of the opening on the outer side of the joint.
[0011] Compared with the existing anti-leakage gas pipeline, the utility model has the following beneficial effects:
[0012] 1. The leak-proof gas pipeline is equipped with a first sealing gasket, a second sealing gasket, a gas filling tube and a third sealing gasket between the protective shell and the protective layer. The first sealing gasket, the second sealing gasket and the third sealing gasket drive the gas filling tube to independently form a group of spaces in sequence. When the pipeline is deformed due to temperature difference, the gas filling tube drives the equipment to expand and contract to avoid deformation of the pipeline due to temperature difference. At the same time, the external equipment applies pressure to the inner wall of the pipeline, causing damage and rupture of the inner wall of the pipeline. At the same time, when the gas leaks, the independent space seals and protects the gas, thereby improving the overall sealing of the equipment.
[0013] 2. The leak-proof gas pipeline has grooves on the inner side of the inner wall of the pipeline. When the grooves drive the inner wall of the pipeline to deform due to pressure, they drive the equipment pressure to deform to provide movement space, while ensuring that the inner wall of the pipeline remains neat, and the reinforcement layer is neatly sleeved on the outside of the inner wall of the pipeline, thereby improving the external protection performance of the inner wall of the pipeline and preventing gas leakage.
