Background technique:
Hand sluice valve be a kind of through torque spanner (or handwheel) thus the valve rod of rotating valve drives flap to move up and down and reaches the purpose of opening/shutting valve.It is widely used in makes opening and closing device on various industry or civilian feedwater, the oil supply pipeline and uses.Thereby ground is used on field, outdoor feedwater, the oil supply pipeline usually, thereby also easily under the situation of non-instruction, had a mind to or by mistake open and close and cause the accident, and stolen water what is more, steals that oil is crafty to be opened valve at an easy rate and steal the medium in the pipeline.Therefore a kind of device of type with lock being set on valve, thereby preventing accident effectively or stolen, still is important.
Summary of the invention:
The purpose of the utility model is in order to overcome the shortcoming of above-mentioned existing technology, to provide a kind of accident that can effectively prevent that the type gate valve magnetic-type with lock that medium is stolen in the pipeline takes place, avoids.
The goal of the invention of the utility model can realize through following technological scheme: magnetic-type type gate valve with lock; Include the gate valve main body; Be provided with valve rod in the gate valve main body, valve rod becomes screw-thread fit with the gate valve main body, the key that is provided with the magnetic lock at the top of gate valve main body and specially joins; This key is provided with magnetic absorption member, and valve rod connects the magnetic lock.
The magnetic lock includes housing, locking closure and magnetic lock core, and housing is fixed on the valve gap, and locking closure activity spinning is on housing, and locking closure is provided with the lockhole that after the magnetic lock core gets into locking closure and lock core are rotated synchronously, and the magnetic lock core becomes synchronously to be rotatably assorted with valve rod.
Between magnetic lock core and valve rod, be provided with link, link is fixedly connected with valve rod, and the magnetic lock core is square, and the link top is provided with and the corresponding square counterbore of the lockhole of locking closure, and the magnetic lock core is placed in the square counterbore fully.
The bottom of locking closure inserts in the housing, and inner walls is provided with circular groove, on the outer wall of locking closure bottom, is provided with sliding pin, and sliding pin is plugged in the circular groove.
The utility model is a kind ofly could open and close gate valve through the special strong magnetic torsion key of special use, and it can accomplish to avoid taking place human accident well, prevents that pipeline medium from being stolen.

Embodiment:
Below in conjunction with accompanying drawing this utility patent is described further.
The type gate valve magnetic-type with lock of present embodiment partly is made up of gate valve main body 1, magnetic lock 2, strong magnetic torsion key 3 three, and this key is powerful torsion key 3.
Gate valve main body 1 is a basic valve, and it comprises compositions such as valve body 11, flap 12, Stem Mut 13, valve rod 14, valve gap 15, gland 16.Valve rod 14 is connected and fixed through Stem Mut 13 and flap 12, and valve rod 14 is threaded for 11 one-tenth with valve body, thus rotation valve rod 14 just can actuate valve stem 14 move upward or downward with flap 12, thereby make valve opening and closing.
Strong magnetic torsion key 3 is the operating stem as input torsion, and it is provided with a cover portion 31, be provided with in the cover portion 31 with locking closure 22 on four grooves 32 cooperating of flange 30, be provided with strong magnetic spare 33 at the top of cover portion 31.
During reset condition, magnetic lock core 23 places in the square counterbore 28 fully, and just magnetic lock core 23 leaves the square lockhole 29 of locking closure 22 fully; At this moment, locking closure 22 breaks away from fully with magnetic lock core 23 and cooperates, under the cooperation of sliding pin 24 and circular groove 26; Locking closure 22 can freely rotate around housing 21; It all is idle running that locking closure 22 is done any rotation, and valve rod 14 can not rotate with link 27, can not drive gate valve and open and close.During opening and closing gate valve, the cover portion 31 of strong magnetic torsion key 3 is covered locking closure 22, make groove 32 and flange 30 on the locking closure 22 in the cover portion 31 transmission torsion that cooperatively interacts; Strong magnetic spare 33 in the simultaneously strong magnetic torsion key 3 is with in the square lockhole 29 in the magnetic lock core 23 inspiration locking closures 22, and at this moment owing to receive the restriction of size, the part of magnetic lock core 23 places in the square lockhole 29; Another part places in the square counterbore 28; Rotate strong magnetic torsion key 3, torsion passes to locking closure 22, and locking closure 22 passes to magnetic lock core 23-link 27-valve rod 14 successively with torsion then; Thereby driving valve rod 14 rotates; Under the threaded function between valve rod 14 and the valve body 11, make valve rod 14 drive flap 12 and do elevating movement, realize the keying of gate valve.Take away when strong magnetic torsion key 3, the magnetic lock core promptly falls back in the square counterbore 28 automatically, replys reset condition, the gate valve locking.The strong magnetic torsion key 3 that turns clockwise is closing gate valve, is rotated counterclockwise strong magnetic torsion key 3 for opening gate valve.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technological scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technological scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technological scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
