The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: the Gate valve with lock structure; Comprise valve body and be located at the valve gap on the valve body; On said valve gap, be provided with valve rod, an end of said valve rod extends in the receiving cavity of valve body, and the valve rod lifting nut that the other end passes on the valve gap links to each other with handwheel; On said bar lifting nut, be arranged with fixedly lock collar and rotation lock collar; Said fixedly lock collar is horizontally fixed on the upper surface of valve gap, said rotation lock collar and fixedly lock collar be horizontally fixed on relatively on the lower end surface of handwheel, on said fixedly lock collar, be provided with down lockhole; Be provided with lockhole on several corresponding on the said rotation lock collar, in said lockhole down and corresponding following lockhole, be interspersed with lock core with following lockhole.Through sheathed pin dish outside the bar lifting nut between handwheel and valve gap and rotation lock collar, fixedly lock collar is fixed on the valve gap upper-end surface, rotates lock collar and is fixed on the handwheel lower end surface; And fixing lock collar with rotate the lock collar correspondence and be provided with upper and lower lockhole, when the downward throttle down of rotation hand wheel, the rotation lock collar is downward synchronously for this reason; The lock core that interts in the upper and lower lockhole in correspondence after valve is closed has fully promptly locked the position of rotating lock collar, and the handwheel that for this reason is attached thereto promptly can't rotate, and valve is fixed on the position of closing; Otherwise also can rotate lock collar after opening valve through the lock core locking; Valve is fixed on the position of setting aperture, need not to change the gate valve internal structure, processing and fabricating is simple; Cost is low, and is convenient and practical.
Fixedly lock collar can be different shapes such as square, polygonal; As preferably; Said fixedly lock collar is a disc, is provided with through hole at the middle part of said fixedly lock collar, and said fixedly lock collar coaxial package is weldingly connected on the valve rod lifting nut and with valve gap; And be provided with the gap between said valve rod lifting nut and through hole, said down lockhole is located near the fixing edge of lock collar outer ring surface vertically.Fixedly the lock collar processing and fabricating is simple for disc; Be weldingly connected with valve gap, means of fixation is simply firm.
As preferably, said rotation lock collar is and pin disk shape and the identical disc of size, is provided with the Hexagon positioning hole at the middle part of said rotation lock collar, and said Hexagon positioning hole is sleeved on the Hexagon outer ring surface of valve rod lifting nut upper end.Rotate lock collar and pin disk shape and big or small when identical, help standardized production, save production cost; Rotate lock collar and be sleeved on the valve rod lifting nut through the Hexagon positioning hole, means of fixation is simple, is convenient to dismounting.
As preferably; On said fixedly lock collar, be provided with 1 to 3 following lockhole; Said down lockhole is along the circumferential direction even cloth on the surface of fixing lock collar, is being provided with lockhole on 8 to 20 on the said rotation lock collar, and the said lockhole of going up is along the circumferential direction spared cloth on the surface of rotating lock collar.Through the following lockhole of fair amount is set, be convenient to select the locked position of lock core according to actual conditions on fixing lock collar; Through rotate evenly be provided with on the lock collar a plurality of on lockhole, valve is gone up at an arbitrary position all can be through the lock core locking, using scope is wide.
Therefore, the Gate valve with lock structure of the utility model has following advantage: through sheathed a pair of lock collar outside the bar lifting nut between handwheel and valve gap, fixedly lock collar is fixed on the valve gap; Rotate lock collar and be fixed on the handwheel, and correspondence is provided with upper and lower lockhole on two lock collars, when handwheel drives rotation lock collar to arbitrary position; Be that available lock core inserts Locked valve behind the upper and lower lockhole, simple in structure, easy to make; Need not to change the gate valve internal structure, cost is low, and is economical and practical.
