Abstract
The utility model relates to a cone valve with non-abrasion sealing faces, wherein a lifting hand wheel (3) is fixedly connected with a nut (4); the nut (4) is mounted on a valve body (1) through a bearing; external threads are arranged at the upper end of a plug cock shaft (2); the external threads of the plug cock shaft (2) is matched with internal threads of the nut (4); a rotating hand wheel (6) is fixedly connected with a worm (8); the two ends of the worm (8) are movably mounted on the valve body (1); a worm wheel (7) is in threaded connection with the worm (8); the worm wheel (7) is fixedly mounted on the plug cock shaft (2) through a pin shaft; and a plug cock (5) is mounted at the tail end of the plug cock shaft (2) and mounted in the valve body (1). The utility model has the advantages that as the lifting hand wheel is rotated to lift the plug cock before opening and closing the valve, the sealing face of the plug cock is separated from the sealing face of the valve body so as to avoid the friction between the sealing face of the plug cock and the sealing face of the valve body, the sealing faces are prevented from being abraded, the service lives of the sealing faces are prolonged, and the torque during opening and closing the valve is reduced.
Description
Technical field
The utility model relates to valve field, relates in particular to the cone valve that a kind of sealing surface does not have wearing and tearing.
Background technique
Existing cone valve, when it opened and closed, its cock sealing surface and valve body sealing surface were located Frotteurism all the time, and after long-term the use, cock sealing surface and valve body sealing surface can be worn, and cause poorly sealed.
The model utility content
The purpose of this utility model is exactly at existing cone valve, when it opens and closes, its cock sealing surface and valve body sealing surface are located Frotteurism all the time, after long-term the use, cock sealing surface and valve body sealing surface can be worn, cause poorly sealed deficiency, and provide a kind of sealing surface not have the cone valve of wearing and tearing.
The utility model is made up of valve body, cock axle, lifting handwheel, nut, cock, rotation hand wheel, worm gear and worm screw, lifting handwheel and nut are fixedly linked, nut by Bearing Installation on valve body, cock axle upper end is provided with outside thread, the outside thread of cock axle matches with the internal thread of nut, rotation hand wheel and worm screw are fixedly linked, the worm screw two ends are movably arranged on the valve body, worm gear links to each other with worm thread, worm gear is fixedly mounted on the cock axle by bearing pin, cock is installed in the cock shaft end, and cock is installed in the valve body.
The cock sealing surface of the valve body sealing surface of valve body 1 and cock is provided with the corrosion resistant alloy layer.
The utility model has the advantages that: because when opening valve and throttle down, all be to promote cock by rotating the lifting handwheel earlier, cock sealing surface and valve body sealing surface are broken away from, thereby do not have between cock sealing surface and the valve body sealing surface and rub, sealing surface does not does not wear and tear, prolonged the working life of sealing surface, the moment of torsion when having reduced valve switch simultaneously.
