Abstract
The utility model relates to a valve anti-theft device, which can prevent that internal parts are dismounted by other people, and the valve is random turned on or turned off. A circular box 3, a square ring sleeve 1 connected by a key body, and a press cap 2 connected by a screw thread are orderly sheathed on a drive nut 12 from up to down. The drive nut arranged outside a valve body can cause a valve core rod to generate displacement after rotating. A circular lock cover 5 is sheathed on the valve core rod 7 arranged on the press cap 2 arranged in the box 3. A dormant lock 9 is inlaid on the edges of the lock cover 5, and the inner wall of the circular box 3 is provided with a ring groove 4 which is extended into by a lock tongue 10. Then, the anti-theft device is formed. The valve can be carried out turning on or turning up by the method that a key is needed to open a lock 9, the lock cover 5 is taken off, a special box wrench sheathed in the square ring sleeve 1 is used for causing the valve to generate displacement. The utility model has anti-theft function.
Description
The utility model relates to and prevents valve upper valve core and the stolen valve alarm of copper cap, comprises after valve body has rotation outward making valve core rod produce the nut of displacement.
As the valve of switch, valuable copper spare is arranged on its valve on the fluid circuit, as spool and nut, these parts are often pulled down by the lawless person and are sold.Especially it is a lot of on oil field well and oil, the water lines valve to be housed, and all exposes in the open air, because administrative staff are limited on the oil field, especially away from the outlying aboveground valve in oil field, part is stolen very serious on the valve, influences field produces.
The purpose of this utility model is to avoid the problem that exists in the above-mentioned present technology, and a kind of valve alarm that prevents that inner body is stolen is provided.
The purpose of this utility model can reach by following technical measures: at square ring set that valve core rod is produced be with in regular turn from lower to upper on the nut of displacement circular box, connect with the key body and the pressure cap that is threaded, in circular box in the circular locking closure that has that is placed on the pressure cap on the valve core rod, inlay built-in lock on the locking closure edge, the annular groove that has dead bolt to stretch on the inwall of circular box constitutes this alarm.
In such scheme, the respective side in built-in lock on the locking closure has upright leg, can make locking closure be in the equilibrium position.Circular the suitable for reading of box has protective cover, in case rainwater and foreign material enter.Can adopt the hexagonal shaped ring set, in rotation process, be done balance.In such scheme, the hexagonal shaped ring set is a switch member on the valve, can make the ring set rotation drive nut by supporting socket wrench rotates, valve core rod produces displacement and the action finishing out and close: but ring set is locked in the box, take off locking closure after opening the lock with the key, the switch motion of valve can be carried out, the design's purpose can be finished by such scheme.
The utility model is compared with above-mentioned present technology can have following advantage: this alarm is installed on the valve, make that switch member is locked in the lock box on the valve, after opening lock box with key, and is furnished with corresponding socket wrench, just can carry out switch motion and can pull down valuable part, in that do not have under the key situation can not switch valve, thereby has preventive effect.
Accompanying drawing is the utility model working principle structural drawing.
To be further described the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing, (valve core rod extension) has square ring set 1 that valve core rod 7 is produced be with in regular turn from lower to upper on the nut 12 of displacements circular box 3, connect with key body 11 and the pressure cap 2 that is threaded outside valve body, and wherein square ring set 1 and pressure cap 2 are put in 3 li in circular box; In the circular locking closure 5 that has that is placed on the pressure cap 2 on the valve core rod 7, form the space chamber that is equipped with square ring set 1 and pressure cap 2 in 3 li in circular box under the locking closure 5 again; On locking closure 5 edges, stud with built-in lock 9, as the built-in lock on drawer, the clothes closet door; At the annular groove 4 that the inwall of circular box 3 has built-in lock 9 upper lock tongues 10 to stretch into, lock back dead bolt 10 with key 8 and snap in annular groove 4, locking closure 5 is locked on the circular box 3, square ring set 1 also is locked in it simultaneously.
On above-mentioned locking closure 5, inwardly upright leg (pillar) 13 is housed, so that locking closure is on the equilibrium position in the respective side of built-in lock 9.Box 3 is suitable for reading to be equipped with the protective cover 6 that can open, in case rainwater and foreign material advance in the box.Square ring set 1 can adopt the hexagonal shaped ring set, it is a switch office in the valve alarm, with special socket wrench rotation ring set 1, the drive transmission nut rotates, make valve core rod 7 produce displacement, but these work need be opened and be carried out after lock 9 takes off locking closure 5, have the function that prevents that the valve internal part is removed.
