Abstract
The utility model relates to a piston dual-purpose lock control valve which comprises a valve, a plunger, a threaded rod and a hand wheel; the utility model is characterized in that the center of the upper end of the valve is equipped with a nut and the threaded rod is penetrated through the nut and connected with the plunger; the side wall of the nut is equipped with a groove which is equipped with a positioning through hole on the inside; a spring and a bidirectional locating pin are arranged in the groove and the threaded rod is equipped with a locating long groove axially; the wall of the upper end of the valve which is as high as the nut is equipped with a lock cavity and the front end of the lock cavity is equipped with a central hole; the central hole is matched with one end of the bidirectional locating pin. The utility model has the advantage that the tightness is good and the utility model realizes the location and locking of the valve threaded rod to realize the location and locking of the valve flux.
Description
Technical field
The utility model relates to the dual-purpose lock control valve of a kind of plunger.
Background technique
At present, pipeline valve is of a great variety on the market, but the most defective that sealing is poor, working life is short, lock control function in management process, mostly not possessing, let alone control locking flow of all existing.Yet, need special messenger's control and management valve in many occasions, be easy to misoperation in this case by the layman, cause unnecessary loss for relevant enterprise, department.
Summary of the invention
The purpose of this utility model provides superior, the long service life of a kind of sealability, can carry out the dual-purpose lock control valve of plunger of conventional control and last lock control.
The purpose of this utility model is realized by following mode:
The utility model comprises valve body, plunger, threaded stem, handwheel, it is characterized in that: the central position, upper end at valve body is provided with nut, threaded stem cooperates to pass with plunger from nut and is connected, on the sidewall of nut, have an inboard groove of positioning through hole is arranged, be provided with spring and a two-way locating stud in the groove, be axially arranged with threaded stem location elongated slot at threaded stem upper edge threaded stem, on the wall of valve body upper end and nut sustained height, be provided with a lock chamber, front end has center hole in the lock chamber, and center hole cooperates with an end of two-way locating stud.
The utility model has the advantages that: good seal performance, realized the normal locking to the valve threaded stem, thereby realized the normal locking to valve flow.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the longitudinal sectional view of Fig. 1;
Fig. 3 is the transverse sectional view of the position, lock chamber of Fig. 1;
Fig. 4 is a kind of structural representation of lockset.
Embodiment
With reference to accompanying drawing 1～3, the utility model comprises valve body 3, plunger 4, threaded stem 6, handwheel 1.Central position, upper end at valve body 3 is provided with nut 2, threaded stem 6 cooperates to pass with plunger 4 from nut 2 and is connected by screw shackle 5, on the sidewall of nut 2, have an inboard groove 12 of positioning through hole is arranged, be provided with spring 10 and a two-way locating stud 9 in the groove 12, be axially arranged with threaded stem location elongated slot 7 at threaded stem 6 upper edge threaded stems, on the wall of valve body upper end and nut 2 sustained heights, be provided with a lock chamber 11,11 front ends have center hole in the lock chamber, and center hole cooperates with an end of two-way locating stud 9.The lockset that cooperates with the utility model has two kinds of forms, a kind of is that lockset is fixedly mounted in the lock chamber 11, the dead bolt of lockset cooperates with lock chamber center hole at the front end of lockset, promotes two-way locating stud 9 with stretching of key control dead bolt and moves, and realizes the normal locking to the valve threaded stem; Another kind is lockset to be put into lock chamber 11 when needs Locking valve threaded stem 6, the structure of its lockset as shown in Figure 4, lockset is made up of lock body 15, lock core 17, dead bolt 20, key 18, pin 13 before the front end of lock body 15 is provided with lock, lock-tongue hole 14 is opened in the side of lock body 15, and dead bolt 20 is contained in the lock-tongue hole 14, is provided with dead bolt driving groove 19 on dead bolt 20, on lock core, be provided with dead bolt driving cog 16, on the sidewall in lock chamber 11, be provided with dead bolt locating slot 8.When need be to the normal locking of valve threaded stem, lockset is put into lock chamber 11, key 18, the dead bolt driving cog 16 of lock core 17 cooperates with dead bolt driving groove 19, dead bolt 20 is positioned in the dead bolt locating slot 8, at this moment, the two-way locating stud 9 of pin 13 promotions moves before the lock, the positioning through hole that the other end locating stud of two-way locating stud 9 passes groove 12 combines with threaded stem location elongated slot 7, valve threaded stem 6 and nut 2 are fixed as one, rotate handwheel 1 threaded stem 6 this moment and rotate simultaneously, owing to the position of nut 2 is fixed, so plunger 4 can not be raised with nut 2.When needs are opened, with key 18 rotational lock cores 17, dead bolt 20 is withdrawed from dead bolt locating slot 8, lockset can take out in lock chamber 11, the locating stud of two-way locating stud 9 one end under the effect of spring 10 enters in the center hole of lock chamber 11 front ends, and the locating stud of the other end returns in the groove 12, and nut 2 and valve body 3 are fixed together, 6 of threaded stems can rotate in nut 2, thereby valve can freely be controlled.
