Abstract
The utility model discloses an automatically controlled magnetic force lock stop valve, its technical scheme main points are automatically controlled magnetic force lock stop valve, including valve body, valve rod, be equipped with the electromagnetic lock on the valve body, the outer plug of electromagnetic lock, be equipped with the lockhole on the electromagnetic lock, the valve body is equipped with the spout of putting to one side, the lower one end of spout is towards the valve rod, be equipped with the gag lever post in the spout, the spacing pole of electromagnetic lock control slides, the valve rod is equipped with the annular groove with the gag lever post joint. Through adopting the electromagnetic lock to realize the reciprocal anchorage of valve body and valve rod, when specifically using, plug the socket circular telegram with the plug earlier, then rotate the key and make inside coil switch on, and then electrical coil's magnetic force pulls back whole gag lever post, accomplish the whole process of unblanking, overall structure easily locks, gag lever post easy operation, and do not have the key just can not open this structure, the security is higher.
Description
Technical field
The utility model relates to a kind of stop valve, and more particularly, it relates to a kind of automatically controlled magnetic key operated lock stop valve.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.When medium is by when entering valve below flap, the resistance overcome required for steering force, be the frictional force of valve rod and filler and the thrust produced by the pressure of medium, the power of the force rate valve opening door of closing valve is large, so the diameter of valve rod wants large, otherwise the fault of valve rod bending can be there is.
At present, pipe break valve on market all has use in places such as oil depot, oil field, thermal substation, tap water field, gas station and chemical plant, after stop valve overall package completes, need valve rod to be screwed into correct position, now valve rod still can be movable, not locked, therefore valve rod may by layman's misoperation, screw out valve rod and cause conducting unnecessary in valve body, needing airtight occasion, misoperation unlatching can produce various adverse consequences.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of automatically controlled magnetic key operated lock stop valve preventing misoperation from screwing out valve rod.
For achieving the above object, the utility model provides following technological scheme: a kind of automatically controlled magnetic key operated lock stop valve, comprise valve body, valve rod, described valve body is provided with electromagnetic lock, described electromagnetic lock external plug, described electromagnetic lock is provided with lockhole, described valve body is provided with tilting chute, and the lower one end of described chute, towards valve rod, is provided with position-limited lever in described chute, described electromagnetic lock controls position-limited lever slippage, and described valve rod is provided with the annular groove with position-limited lever clamping.
The utility model is set to further: described electromagnetic lock and valve body removably connect.
The utility model is set to further: described valve body is also provided with Removable hook, and described valve stem tip is provided with the hangers hooked together with Removable hook.
Compared with prior art, the utility model has the advantage of: realize interfixing of valve body and valve rod by adopting electromagnetic lock, during concrete use, first plug is plugged socket energising, then rotating key makes Inside coil be energized, and then whole position-limited lever is pulled back by the magnetic force of hot-wire coil, complete whole process of unblanking; Overall structure easily locks, and position-limited lever is simple to operate, and does not have key just can not open this structure, and Security is higher.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model automatically controlled magnetic key operated lock stop valve embodiment;
Fig. 2 is the partial view A of Fig. 1;
Fig. 3 is the partial view B of Fig. 1.
Reference character: 1, valve body; 2, valve rod; 3, electromagnetic lock; 4, plug; 5, lockhole; 6, chute; 7, position-limited lever; 8, annular groove; 9, Removable hook; 10, hangers.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model automatically controlled magnetic key operated lock stop valve embodiment is described further.
A kind of automatically controlled magnetic key operated lock stop valve, comprise valve body 1, valve rod 2, valve body 1 is provided with electromagnetic lock 3, electromagnetic lock 3 external plug 4, and electromagnetic lock 3 is provided with lockhole 5, lockhole 5 needs corresponding key ability rotating opening, valve body 1 is provided with tilting chute 6, and the lower one end of chute 6, towards valve rod 2, is provided with position-limited lever 7 in chute 6, electromagnetic lock 3 controls position-limited lever 7 slippage, and valve rod 2 is provided with the annular groove 8 with position-limited lever 7 clamping; Under normal circumstances, Action of Gravity Field makes position-limited lever 7 slide to annular groove 8, also just makes valve body 1 mutually retrain with the activity of valve rod 2, namely achieves locking structure; Where necessary, insert socket energising by plug 4, and then insert key, rotate key, Inside coil energising magnetic force is strengthened greatly, drives position-limited lever 7 to move by magnetic force and depart from annular groove 8, namely make locking structure unlock, valve rod 2 can take out in valve body 1.
Preferably, electromagnetic lock 3 and valve body 1 removably connect; Specifically can adopt that screws bolts is this is connected and fixed mode, be convenient to maintenance, easy accessibility on the one hand, can the part of in time repair and replacement internal damage, that can take out on the other hand position-limited lever 7 coats lubricant oil to after its cleaning of outer surface, prevents position-limited lever 7 from stuckly can not to use in chute 6, locks.
Fig. 3 gives the specific embodiment of the Removable hook 9 on valve body 1, valve rod 2 top is provided with the hangers 10 hooked together with Removable hook 9, add this safe locking structure, after valve rod 2 turns to correct position, Removable hook 9 is hung on hangers 10, remind layman not open, ensure its Security, avoid the accident of meeting accident, where necessary, take off hook rotation valve rod 2 and just can carry out specific operation.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
