The technical proposal is that a housing1 is used as an anti-theft device, and a fastening bracket5 is welded at the interval of the lower part of the internal wall in the housing1; a circular hole matching with the bolt at the upper cover of the valve is prefabricated at the interval of the lower part of the internal wall in the housing1; a lock block3 is welded at the interval of the upper part of the internal wall in the housing1, and all the lock blocks 3 are held at the same horizontal plane; an opening6 is arranged at the one side of the housing1, and a lock nose4 is welded near the one side of the opening6; a lock hole is arranged on the lock nose4; a top cover7 is arranged on the lock block3, and the top cover7 is a circular steel plate whose diameter is slightly smaller than the inner diameter of the housing1; a handle8 is welded on the top cover7; a lock jaw9 matching with the lock block3 is welded at the lower surface of the top cover7, and the lock jaw9 is L-shaped; the projecting part of the lower side of the lock jaw9 laps and matches with the upper side of the lock block3; a lock suspension nose10 is hinged at the lower side of the top cover7 near the opening6, and the lock suspension nose10 laps and matches with the lock nose4. The safety and anti-theft performances of the valve anti-theft device are improved. The utility model has the advantage of convenient demount and use.

Description

A kind of valve alarm

One, technical field: the utility model relates to a kind of valve anti-theft device, especially a kind of valve alarm.

Two, background technique: at present the supporting valve of oil field oil storage tank, oil pipeline, tracheae line is more and more, damages the valve stolen, to steal the gas phenomenon more and more serious.The anti-theft measure of existing valve mainly is to adopt special-purpose wrench to come Open valve, and the valve of this mode is exposed outside, is broken up bad by direct sled easily; Be that valve is welded in the steel plate case of a sealing in addition, break up badly that influence is normal to be used, bring to the production in oil field to seriously influence though be difficult for sled.

Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, the practical valve alarm of providing convenience.

Its technological scheme is: the steel pipe that adopts caliber to be fit to is made the housing 1 of alarm, be welded with the securing bracket 5 of two above quantity at interval in housing 1 inwall bottom, all securing brackets 5 are at same horizontal plane and be shaped on the circular hole that cooperates with bonnet bolt on the valve in advance, housing 1 are fastened on the valve base that adapts to specification by securing bracket 5; Be welded with the lock dog 3 of two above quantity at interval in the upper inside wall of housing 1, all lock dogs 3 are curved and be maintained at the same horizontal plane; Offer unlatching mouth 6 in a side of housing 1, be connected at a close face down bonding of opening mouth 6 and locking nose 4, lock nose 4 and be provided with lockhole, unlatching mouthful 6 outside welds are connected to pick-proof and bend mouth 2.Be placed with top cover 7 on lock dog 3, top cover 7 is circular steel plates that a diameter is slightly less than housing 1 internal diameter, is welded with handle 8 above; The lower surface of top cover 7 is welded with the lock pawl 9 that cooperates with lock dog 3, and lock pawl 9 is L-shaped, and the projection below it cooperates with overlap joint below the lock dog 3; At hinged lock hanging nose 10 below the top cover 7 of opening mouthful 6 positions, lock hanging nose 10 cooperates with lock nose 4 overlap joints.

Effect of the present utility model is: housing is fixed by the securing bracket and the valve body of bottom; housing upwards is inserted in valve handle in it; top cover is placed on above the lock dog; after rotating to an angle; top cover and lock dog are taken drive fit; the nose of lock hanging simultaneously cooperates with the lock nose; by curved mouthful of pick-proof that lock hanging is locked on the lock nose, in alarm, lock is also in alarm whole valve upper part protection; because curved mouthful of protection of pick-proof arranged; can't directly prize or impact lock or lock hanging nose from the outside, have only with key the lock hanging nose is pulled down in the lock unlatching, will just can reinstate valve after the top cover opposite spin proposition; so its safety; theftproof performance improves greatly, also easy disassembly and use.

Four, description of drawings: accompanying drawing 1 is a longitudinal sectional view of the present utility model; Accompanying drawing 2 is the A-A views among Fig. 1.Among the figure 1, housing 2, curved mouthful 3 of pick-proof, lock dog 4, lock nose 5, securing bracket 6, open mouthfuls 7, top cover 8, open handle 9, lock pawl 10, lock hanging nose.

Five, embodiment:

Select the steel pipe of suitable size to make the housing 1 of alarm according to the valve specification, housing 1 internal upper part is welded with lock dog 3 and lock nose 4, housing 1 bottom is welded with three securing brackets 5 at interval, housing 1 top is offered near the position, right side of lock nose 4 and is opened mouth 6, the outside is welded with opens the lock pick-proof curved mouthful 2, be welded with unlatching handle 8 at top cover 7 upper surfaces, be welded with lock pawl 9 and lock hanging nose 10 at top cover 7 lower surfaces.The valve alarm that processes is placed on the valve that adapts to specification; fixing by screw and securing bracket 5; top cover 7 put into screw; lock hanging nose 10 is hung and to lock nose 4; tapered end is hung into lock nose 4 locked by the pick-proof mouth, in alarm, opening behind the lock with key without the operator on duty can't operated valve valve protection; can not damage valve with the tup metal body, reach antitheft effect.
