低阻力燃气止回阀，液化气，天然气逆止阀应用在燃气管道,液化石油气站,燃煤系统，加油站，供暖、煤气炉、天然气、液化石油气、燃气、煤气、空气、沼气钢厂等管道上作单向启闭，阻止介质逆流 Low resistance gas check valves, liquefied petroleum gas, and natural gas check valves are used in gas pipelines, liquefied petroleum gas stations, coal-fired systems, gas stations, heating, gas stoves, natural gas, liquefied petroleum gas, gas, gas, air, biogas steel plants, and other pipelines to perform one-way opening and closing to prevent reverse flow of the medium
进口低阻力燃气止回阀 液化气单向阀 天然气逆止阀慨述 Express with regret
低阻力燃气止回阀（天然气逆止阀）是采用尼龙或PTFE为密封面，软密封材料阀座性能可靠，减缓介质压力的冲击，防止静电而产生了火花，保护阀门及管道，适用燃气管道控制接通和截断管路介质的启闭装置，阻止介质逆流 RETZ The gas check valve (natural gas check valve) uses nylon as the sealing surface. The soft sealing material has reliable valve seat performance, which can reduce the impact of medium pressure, prevent sparks caused by static electricity, protect the valve and pipeline. It is suitable for the gas pipeline to control the opening and closing of connecting and cutting off the pipeline medium, and prevent the reverse flow of medium
