耐蝕特點有優良抗還原性酸介質。特別是在高溫氟化氫氣體和氫氟酸溶液中有優良的耐蝕性，耐任何濃度氫氟酸溶液的腐蝕。主要應用于高溫氟化氫氣體和氫氟酸溶液工況，自動陰止流體倒流的閥門。止回閥的閥瓣在流體壓力作用下開啟,流體從進口倒側流向出口倒.當進口側壓力低于出口倒則,閥瓣在流體壓差本身重力等因素作用下自動關閉以防止流體倒流,廣泛適用于電站、化工、水力等行業。
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.
