Abstract
The utility model relates to a fast switch valve used for the switching of fluid, which is composed of a valve body, a valve cap, a valve core, a handle, a sealing ring, etc., wherein, the top end of the valve cap is sealed off and the lateral surface near the upper part of the top end is provided with a spiral groove which is vertical to an axial line and rises around the axial line; the upper part of a lift shaft of the valve core, which corresponds to the spiral groove, is provided with a handle lever which is vertical to an axial center while the lower end of the lift shaft of the valve core is provided with a valve sheet which is vertical to the axial line, and both of the upper and the lower sides of the valve sheet are provided with leak-proof sealing rings. The utility model has the advantages of simple structure, convenient use and long service life.
Description
The utility model is a kind of snap switch valve that is used for fluid switch, and structure is the poppet valve form.
Existing various valve mechanism all has deficiency, the employing screw lift, serious wear is damaged easily; The ball valve class formation is simple, but normal generation the in wearing and tearing back leaked.
The utility model will design a kind of simple in structure exactly, easy to use and non-damageable snap switch valve.
The utility model is made up of valve body, valve gap, spool, handle and seal ring etc., the valve gap top closure, valve gap has and axis normal and the spiral chute that rises around axis near the upper side on top, spiral chute first half slope is bigger, the Lower Half slope is less, is convenient to like this when valve closing by friction locking.The position corresponding with spiral chute, spool lift shaft top has the screw vertical with the axle center, handle is a direct rod shape, front end is screw rod and passes spiral chute and be contained in the screw on the spool lift shaft, and the size of handlebar and spiral chute cooperation place can be slided movingly in spiral chute with handlebar and to be advisable.There is the valve block with axis normal spool lift shaft lower end, and the leakage proof seal ring all is equipped with in the valve block top and bottom, and top is bowl-shape, makes with rubber, is used for preventing when valve opening spool lift shaft periphery leakage; Below make for copper ring, corrosion-resistant and wear and tear.
Accompanying drawing is a structural representation of the present utility model.
Valve body 4 can be made with cast iron with valve gap 1, valve gap 1 top closure, and valve gap 1 has and axis normal and the spiral chute 8 that rises around axis near the upper side on top, and spiral chute 8 first half slopes are bigger, and the Lower Half slope is less.Spool lift shaft 3 tops and spiral chute 8 corresponding positions have the screw vertical with the axle center, handle 2 is a direct rod shape, front end is screw rod and passes spiral chute 8 and be contained in the screw on the spool lift shaft 3, the size of handlebar 2 and spiral chute 8 cooperation places can be advisable in spiral chute 8 with handlebar 2 in slip movingly.There is the valve block 6 with axis normal spool lift shaft 3 lower ends, and leakage proof seal ring 5 and 7 all are equipped with in valve block 6 top and bottom, and top is bowl-shape, makes with rubber, are used for preventing when valve opening spool lift shaft periphery leakage; Below make for copper ring, corrosion-resistant and wear and tear.During use, clockwise direction is pulled handlebar 2, and spiral chute 8 driving handle bars 2 drive spool lift shaft 3 and glide, and valve block 6 covers valve closing, handlebar 2 and the locking of spiral chute 8 frictionallies with water passage hole.Counterclockwise pulling handlebar 2 can be with valve open.
