sealing
Key words:
High pressure hydrogenation check valve
The types of valve that can be used in the environment of hydrogen gas (including hydrogen sulfide), hydrogen gas, and hydrogen gas oil (including hydrogen sulfide). If the nominal pressure is PN100 or Class600, the flange in the valve body and the valve cover adopt a flange bolt connection structure. For the valve with nominal pressure ≥ PN160 or Class900 and nominal ruler ≥ DN50, the valve is designed as a sealed structure, and SS flexible metal sealing ring is placed in the middle cavity for internal pressure or hard welding at the corresponding parts of the inner cavity of SS flexible metal sealing ring. Pressure seal valve cover; Internal pin rocker pin design without external leakage; Seal ring contact area surfacing hard metal composite layer to ensure reliable pressure sealing performance; Valve identification, valve seat seal surfacing or Steite (Steite) drill-based hard surfacing is wear-resistant, temperature-resistant, corrosion-resistant, friction-resistant, and has good service life; the basic principle of pressure sealing valve;
