耐蚀特点有优良抗还原性酸介质。特别是在高温氟化氢气体和氢氟酸溶液中有优良的耐蚀性，耐任何浓度氢氟酸溶液的腐蚀。主要应用于高温氟化氢气体和氢氟酸溶液工况，自动阴止流体倒流的阀门。止回阀的阀瓣在流体压力作用下开启,流体从进口倒侧流向出口倒.当进口侧压力低于出口倒则,阀瓣在流体压差本身重力等因素作用下自动关闭以防止流体倒流,广泛适用于电站、化工、水力等行业。
The corrosion resistance features excellent resistance to reducing acid media. Especially in high-temperature hydrogen fluoride gas and hydrofluoric acid solution, it has excellent corrosion resistance and resistance to corrosion of any concentration of hydrofluoric acid solution. Mainly used in high-temperature hydrogen fluoride gas and hydrofluoric acid solution working conditions, automatic negative stop fluid backflow valve. The valve disc of a check valve opens under the action of fluid pressure, and the fluid flows from the inlet inverted side to the outlet inverted side. When the inlet side pressure is lower than the outlet inverted side, the valve disc automatically closes under factors such as the gravity of the fluid pressure difference itself to prevent fluid backflow. It is widely used in industries such as power plants, chemical engineering, and hydropower.
