Abstract
The utility model relates to the technical field of valves, in particular to an improved magnetic lock control ball valve. According to the improved magnetic lock control ball valve, the upper portion of a valve rod is sleeved with a locking sleeve, the locking sleeve comprises a sleeve body, a key cylinder is arranged in the sleeve body, a spring and a first strong magnet are arranged between the upper end of the key cylinder and the sleeve body, installing holes are formed in the lower portion of the key cylinder, and are used for assembly of balls, an annular groove is formed in the upper portion of the valve rod, the upper portion of the locking sleeve is sleeved with an unlocking sleeve in a cooperative mode, and a second strong magnet is arranged in the unlocking sleeve. Due to the facts that the valve rod is sleeved with the locking sleeve and the unlocking sleeve, and the locking sleeve and the unlocking sleeve are used in cooperation, the structure is simple, and use is convenient; when the improved magnetic lock control ball valve needs to be opened, the locking sleeve is sleeved with the unlocking sleeve in a surrounding mode, the key cylinder breaks away from the annular groove together with the balls so as to be opened under the action of force of the spring through the like-pole repellent effect between the first strong magnet and the second strong magnet, and the locking sleeve and the unlocking sleeve are taken down; when the improved magnetic lock control ball valve needs to be locked, the upper portion of the valve rod is sleeved with the locking sleeve, downward pressing is carried out so that the key cylinder and the balls can be used in cooperation to be connected with the annular groove in a locked mode, and theft and accidental opening can be effectively prevented.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of improved magnetic lock-control ball valve.
Background technique
At present, valve mechanism of the prior art generally comprises valve body, is arranged at spool and valve rod in valve body.During use, by the handle on rotating valve, band ovable valve stem, spool action, thereby reach the flow channels of closing or opening in valve body, still, valve applications of the prior art is in gas pipe line time, handle on valve anyone can be simple and relax operation, while especially valve being arranged to the main valve of gas pipe line, people are easy to open valve and usurp coal gas, thereby owner is caused to economic loss.In addition, the valve of the type is easy to, in careless situation, it surprisingly be opened, and can cause gas leakage like this, and then life is threatened safely.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of and can effectively prevent from usurping and prevent unexpected unlatching, improved magnetic lock-control ball valve simple in structure, easy to use.
For achieving the above object, the utility model is by the following technical solutions: a kind of improved magnetic lock-control ball valve, comprise valve body, in valve body, be provided with spheroid, spheroid upper end is connected with valve rod, valve rod upper end is connected with handle, described valve rod top is arranged with lock tube, described lock tube comprises body, in body, be provided with lock core, between the upper end of lock core and body, be provided with spring and the first strong magnet, the bottom of lock core offers for installing the mounting hole of ball, described valve rod top offers the circular groove being connected with ball, described lock tube top engage sleeves is provided with the cover of unblanking, unblank to be provided with the second strong magnet repelling with the first strong magnet same sex in cover.
Wherein, described body inwall is provided with the card convex ring of being convenient to lock core and ball locking.
Wherein, described in unblank cover comprise outer sleeve, in outer sleeve, be provided with the second strong magnet ring.
Wherein, described stem lower portion is provided with for limiting the trap block of distance of lock tube.
The utility model beneficial effect is: the utility model comprises valve body, in valve body, be provided with spheroid, spheroid upper end is connected with valve rod, valve rod upper end is connected with handle, described valve rod top is arranged with lock tube, described lock tube comprises body, in body, be provided with lock core, between the upper end of lock core and body, be provided with spring and the first strong magnet, the bottom of lock core offers for installing the mounting hole of ball, described valve rod top offers the circular groove being connected with ball, described lock tube top engage sleeves is provided with the cover of unblanking, unblank to be provided with the second strong magnet repelling with the first strong magnet same sex in cover, the utility model is by sheathed lock tube on valve rod and the cover of unblanking, be used in conjunction with, simple in structure, easy to use, when need are opened valve, unlocking link is enclosed within on lock tube, by the same sex repulsive interaction of the first strong magnet and the second strong magnet, makes lock core under the effect of spring force, the constraint that departs from circular groove together with ball is opened, and lock tube and the cover of unblanking are taken off, then spanner is connected on valve rod and pulls handle, can open valve, when need locking valve, after first valve being pulled and closed by handle, lock tube is set in to valve rod top, press down lock core and ball are coordinated and circular groove locking, can effectively prevent from usurping and prevent so unexpected unlatching.
