Abstract
The utility model discloses an internally-arranged locking ball valve, and relates to a ball valve structure with a locking device. The internally-arranged locking ball valve is mainly composed of a valve body, a valve deck, a valve base, a sphere valve core, a valve rod, the locking device and the like. The locking device is internally arranged inside the valve body. Due to the internally-arranged structure, random opening and closing of the valve are limited, and the locking function is not easily lost by man-made damage. Meanwhile, the locking device is unlocked by magnetic attraction by a starting and closing wrench with an unlocking magnetic block. Compared with a traditional mechanical lock structure, the ball valve structure has the advantages that the service life can not be shortened by causes like abrasion, and the locking function can not be lost. A top cover with different colors is further additionally arranged on the top face of the locking device, and the current stating and closing state of the valve can be distinguished according to the colors of the top cover, so that the current starting and closing state of the valve is effectively prevented from being determined by other detections during pipeline maintenance or limitation for use, and working efficiency is also greatly improved.
Description
Technical field
The utility model relates to a kind of ball-valve structure, refers in particular to built-in locking ball valve.
Background technique
The advantage such as ball valve has that fluid resistance is little, compact structure, sealing are reliable, easy to operate, easy to maintenance, thereby be widely used in the aspects such as oil, chemical industry, generating, aviation and hot-water heating, especially at present the manual ball valve directly connecting with pipeline, because it is simple in structure, easily operation, therefore become in daily life the most common valve kind.At present, the keying of conventional manual ball valve is unrestricted, and anyone is random switch, and this special occasions that need carry out valve opening and closing by full-time staff to some has brought potential safety hazard, is also not easy to the control that some pipeline restriction is used.Therefore, can limit the ball valve with locking functions of random switch is applied in these occasions, but traditional band locking functional ball valve adopts mechanical lock structure mostly, in use easily wear and tear and lost efficacy, and, this locking closure exposes to valve body top mostly, easily suffers artificial destruction, makes it lose locking functions.Meanwhile, with the ball valve of locking functions, generally all by locking closure, replaced handle, this has also lost the function of handle indication valve open/close states.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect of prior art and provides a kind of locking reliably, not to be subject to destruction, can realize the built-in locking ball valve of valve opening and closing state indication.
Technical problem of the present utility model is achieved through the following technical solutions:
A locking ball valve, comprises valve body and is sealedly connected on the valve gap on valve body, is provided with valve seat and rotary seal and is bearing in the ball valve core in valve seat in this valve body, is provided with water port on ball valve core; Described valve body top is provided with locking closure, between this locking closure and ball valve core, be provided with the valve rod of rotary seal, valve rod lower end and ball valve core are in transmission connection, described valve body top is provided with upwardly extending disjunctor cover, described locking closure is built in this disjunctor cover, and this locking closure comprises that being arranged on disjunctor overlaps the lock core of end face and the lock tube that suit is fixed on lock core bottom; Described lock core end face is provided with the unlock hole that opening exposes, and lock core outer surface is provided with radial blind holes, and locking ball and the outside spring of pushing tow locking ball are installed in this radial blind holes; Described lock tube is provided with the through hole equipped with described locking ball, and this locking ball is subject to spring push to be fastened in through hole and is formed with exposed junction; Described disjunctor cover top inner surface is provided with a circle internal projecting ring; The exposed junction contact of described locking ball is on the leave from office terrace of this internal projecting ring.
In the unlock hole of described lock core end face, be provided with top cover or join and be inserted with keying spanner.
Described keying spanner is to consist of driving end and the spanner handle being connected on driving end, and this driving end end is provided with keying groove, and this spanner handle end is provided with the magnetic patch of unblanking.
Described locking ball external diameter is greater than the through-hole aperture on lock tube.
The suit fixed structure of described lock tube and lock core bottom be on the internal surface of lock tube, be provided with a circle circumferential ring around chamfering bulge loop, corresponding on the outer surface of lock core, be provided with a circle circumferential ring around annular groove, described chamfering bulge loop is fitted in annular groove.
Described lock core top outer circumferential face is provided with the outer convex shoulder of a circle, and it is equipped that the terrace of appearing on the stage of the internal projecting ring at this outer convex shoulder and disjunctor cover top is made axially locating.
Described lock core bottom outer circumferential face is made as the conical surface.
Described valve body top is provided with the inner convex platform that extends upward and be arranged in disjunctor cover, and described valve rod is arranged in inner convex platform, is provided with the two pass "O"-ring that forms rotary seal between this valve rod and inner convex platform.
Described valve rod upper/lower terminal is equipped with flat axle.
Compared with prior art, the utility model be mainly by the built-in design of locking closure in valve body, this built-in structure had both limited any switch of valve, was not also subject to artificial destruction and lost locking functions.Meanwhile, this locking closure is to do magnetic absorption release by a keying spanner with the magnetic patch of unblanking, and its relatively traditional mechanical lock structure there will not be because of the problem that wearing and tearing etc. are former thereby reduce the life-span and then cause locking functions to lose efficacy.And locking closure end face also can have additional the top cover of different colours, can distinguish the open/close states when early gate according to the color of top cover, therefore can effectively avoid when pipeline is safeguarded or when restriction uses, also need by detection, to determine the open/close states that valve is current in addition, this has also greatly improved working efficiency.
