Abstract
The utility model provides a gate valve, which comprises the following components: a valve body, the valve body in be equipped with the valve plate, the valve plate is connected with the valve rod, is equipped with the valve gap on the valve body, mouthful gasket in being equipped with between valve body and the valve gap through stud with first nut is fixed be in the same place between valve body and the valve gap, is equipped with the packing cavity in the valve gap, the packing cavity bottom is equipped with to pack and fills up, is equipped with gland on the packing cavity, is equipped with the hand wheel of being connected with the valve rod on the valve gap, fix through valve -stem nut and lock nut and be in the same place, the valve body in be equipped with sealed face of flashboard and valve seat seal face, the sealed face of flashboard be the plane, the valve seat seal face is the inclined plane, the beneficial effect of the utility model: this product is with the sealed face of original plane flashboard and the valve seat seal face changes the sealed face of flashboard into and valve seat seal face one side is the inclined plane for plane, one side, and this kind of structure makes sealing performance better, and frictional force is littleer, opens and close the moment of torsion to alleviate, and life is longer.
Description
Technical field
The utility model relates to valve field, particularly a kind of Novel Brake Valve.
Background technique
Ram seal face now in gate valve commercially and sealing surface of seat are all planes, and sealing is poor, and frictional force is large, and open and close torque is large, and working life is short, so need a kind of Novel Brake Valve just can address these problems.
Model utility content
For existing technical deficiency, the utility model provides a kind of Novel Brake Valve.
To achieve these goals, technical solution adopted in the utility model is: a kind of Novel Brake Valve, comprise valve body, valve plate is provided with in described valve body, valve plate is connected with valve rod, valve body is provided with valve gap, middle mouth pad is provided with between valve body and valve gap, be fixed together by stud and the first nut between valve body and valve gap, packing cavity is provided with in valve gap, Packing seat is provided with bottom packing cavity, packing cavity is provided with Gland, valve gap is provided with the handwheel be connected with valve rod, be fixed together by Stem Mut and locking nut, Bearing housing is provided with between Stem Mut and valve gap, swing bolt is provided with between Gland and valve gap, swing bolt one end and pinned connection, one end is fixed by the second nut, be provided with ram seal face and sealing surface of seat in described valve body, described ram seal face is plane, and sealing surface of seat is inclined-plane.
Filler is filled with in described packing cavity.
Described filler is soft graphite.
The beneficial effects of the utility model: it is plane that this product changes original plane ram seal face and sealing surface of seat into ram seal face and sealing surface of seat side, side is inclined-plane, and this structure makes sealability better, and frictional force is less, open and close torque alleviates, longer service life.
