The environment with good sealing can reduce external impurities from entering the pipeline, and the aging of the main pipeline is prevented from being accelerated due to the chemical reaction or physical abrasion of the impurities and the fuel gas.
As a further improvement of the above, the height of the sealing gasket is greater than the height of the mounting groove.
Through above-mentioned technical scheme, sealing gasket highly is greater than the mounting groove height and can ensure when connecting that sealing gasket can fully be extruded to fill the gap at junction part better, improve sealed effect, further protect the trunk line internal environment, reduce the influence of ageing factor.
As a further improvement of the scheme, the surface of the main pipeline is sleeved with an upper pressing plate, the bottom of the upper pressing plate is hinged with a lower pressing plate, and bolts are arranged inside the upper pressing plate.
As a further improvement of the above, the bottom of the bolt penetrates the bottom of the lower pressing plate.
Compared with the prior art, the utility model has the beneficial effects that:
According to the utility model, the protective film is wound on the surface of the main pipeline, then the handle is rotated to drive the threaded rod to rotate, the handle rotates to move under the action of the threaded sleeve until the bottom of the first connecting plate is contacted with the top of the second connecting plate, then the threaded rod is continuously rotated, the surface of the arc-shaped pressing plate is contacted with the surface of the protective film, the protective film is fixed on the surface of the main pipeline to protect the main pipeline, and meanwhile, the subsequent disassembly of the protective film is also facilitated through the threaded rod.
According to the utility model, the sealing gasket is arranged to seal the connection position between the two flanges when the pipelines are connected, so that the safety of gas circulation in the pipelines is ensured.
