Tungsten carbide erosion resistant stopcock valve

Abstract

The utility model discloses a kind of tungsten carbide erosion-resistant plug valves, including valve body, vertically through passageway is separately provided in it, it includes from lower to upper continuous first vertical section, second vertical section and third vertical section;Horizontal through passageway, including the first horizontal section of two ends and the second horizontal section being communicated therewith;Valve cover, its fixed inner sleeve is in the first vertical section;Plug, its cooperation inner sleeve is in the second vertical section and is rotatably connected with it;Sealing member, its gap of filling second horizontal section and plug is equipped with sealing assembly at the connecting end surface of sealing member and second horizontal section;Plug rod, one end is fixedly connected with plug, the other end is rotatably connected with third vertical section;Each through passageway and each component sealing surface are coated with tungsten carbide.The utility model solves the problem that plug valve inner channel and sealing surface are not resistant to erosion, poor sealing performance, short sealing life under harsh working conditions, leading to valve cannot be efficiently stopped, short service life and other problems.
