Description
Technical field
The utility model relates to mud valve, is specifically related to a kind of metallic seal mud valve.
Background technique
The gate valve that domestic present oil field and mine use; owing to contain silt particle and hard point and sulphur-containing substance in the underground medium; in the motion of fluid, spool and valve seat are washed away and corrode; cause the valve plate and the prooving of valve seat and corrosion very fast, leakage phenomenon is arranged when closing, often need to change; not only the cost of production expense increases; influence manufacturing efficiency, the more important thing is that the mine shutdown maintenance replacing midway loss of working continuously is quite big, and have unsafe factor.
Summary of the invention
The purpose of this utility model is: a kind of metallic seal slurry pump is provided, with the metal covering between valve seat, seat ring, the valve plate is primary seal, with the imperial pad of richness is the best effects that the mode of auxiliary seal reaches sealing, this valve seals after adopting valve, valve plate has strengthened sealing effect by the pressure of fluid squeeze valve seat ring and valve seat backward, has prolonged working life, reduce cost of production, improved manufacturing efficiency.
Technical solution of the present utility model is: this metallic seal mud valve comprises valve gap, rich imperial gasket seal, valve plate, seat ring, valve rod, valve body, upper valve base seal ring, valve seat, lower valve base seal ring, fixed plate, mounting plate and valve seat and upper valve base seal ring and lower valve base seal ring in valve body, valve plate and seat ring are installed in valve body, valve rod is installed in valve gap.
In the metallic seal mud valve of the present utility model, be provided with rich imperial gasket seal between valve body and the valve gap.
In the metallic seal mud valve of the present utility model, valve gap is connected with bolt with valve body.
During work, rotation hand wheel is a full-gear when being up to spacing position; Rotation hand wheel is a closed condition during to descending spacing position.
The utility model is simple in structure, and is easy to operate, good sealing effect, long service life.
Description of drawings
