Gas pipeline valve characteristics

    With the development of the natural gas pipeline industry, the amount of natural gas pipeline Copper Gas Valves increasing natural gas pipeline valves and general valves are different. Specifically the following points:
     1, the material
     Because of the natural gas pipeline transportation desulfurization ago contains a lot of hydrogen sulfide (which is a highly toxic and corrosive gases, it reacts iron sulfide and iron, can be flaky peeling, pitting wear machinery). Even after gas desulfurization process and other processes, there are still remnants of hydrogen sulfide. Therefore, selection must be selected pipeline valve corrosion resistance to sulfur material.
    2, leakage
    Most of the natural gas pipeline network built on the edge of the city, unlike the general operation and management of the factory, workers often have the operation, maintenance and inspection. Average city gas pipeline are hundreds of kilometers, only regular patrols, inspection, and sometimes complicated pipeline through the region, media leaks could result in serious fires. Especially from the city closer to the pipeline, to prevent leakage of the Gas Heater Control Valve is particularly important.
    Gas valve leakage requirements are very strict, usually buried and more important valves are used all-welded body structure. In order to ensure the sealing performance of pipeline valves require valve with excellent corrosion resistance, wear resistance, self-lubrication and elasticity. In recent years, the development of polymer materials pipeline Gas Grill Valves seal material selection provides a broad selection of the world, such as Teflon, nylon, acrylonitrile-butadiene rubber (NBR), a special synthetic rubber (VITON) as the.
