Abstract

The utility model relates to a theft-proof stop valve, which is characterized in that the shaft of the stop valve is used as a shaft line which is orderly provided with a pad, an anti-crashing pad, a stop valve cover, a filling barrel, a pressing cover, a filler and a pressing sleeve of the filler. A cross lock is arranged on the shaft of the stop valve along the vertical direction, a lock bolt is baffled below the large outer circle of the filling barrel, and all the components are covered in a protecting cover. An outer shell playing the protective and decorative functions is arranged on the protecting cover, the shell of the cross lock is pined on a guiding sleeve of a lock core through a guiding pin, and therefore, the lock bolt on the cross lock only can be moved along a spiral groove. The outer shell of the cross lock is pined with the protecting cover through a positioning lock. Under the condition without a key, since the protecting cover can not be taken off, a thief can not steal the bicycle.

Description

Theft-proof valve

The utility model relates to a kind of arbitrarily Theft-proof valve of unlatching that prevents.It is used for plumbing and heating system, arbitrarily opens pipe valve to have avoided the people, usurps water or heating installation, causes energy waste, is unfavorable for property management again.

Knownly be used for antitheft pipe valve and have following several: 1, on the pipe valve that uses, handwheel is taken off; 2, Gland is compressed, it is motionless that handwheel is twisted; 3, with a capsule, pipe valve is buckled in the inside, the outside locks; 4, use chain lock on pipeline on the pipe valve handwheel, handwheel can not be rotated; 5, be stained with the strip of paper used for sealing or the lead sealing of screwing on.Above method with simple tools such as wrench, screwdriver, pliers, saws, just can be removed strick precaution in very short time.Be difficult for being found after most of pipe valve of while is stolen, recover former state easily, cause energy waste, be unfavorable for property management.

The purpose of this utility model provides a kind ofly anti-usurps pipe valve, and its compact structure is firm reliable, easy to use, helps property management, searches appropriator easily.

Structure below in conjunction with Fig. 1,2 pairs of model utilitys is commented as follows: accompanying drawing is depicted as pipe valve and is in anti-theft state.The utility model is to invent on the basis of common pipe valve.Its structure also comprises pipe valve body (1), pad (2), pipe valve lid (4), filling tube (6), gland (7), pipe valve axle (8), voussoir (19) is characterized in being axis with pipe valve axle (8), closed assembly has pad (2) successively, crash pad (3), pipe valve lid (4), filling tube (6), gland (7) is pressed in filler (10) in the filling tube (6) by filler gland (9).Cross lock assembly (13) becomes 90 ° to be installed on the protecting casing (5) with the axis of pipe valve axle (8), and the lock (18) that is positioned, and itself and protecting casing (5) are locked together.Be processed with spiral guide slot (14) on the dead bolt (15), lead in pin (12), with lock core guide sleeve (17), lock together with cross lock housing (11), dead bolt (15) is blocked in when antitheft condition shape under the big cylindrical on the filling tube (6).Above-mentioned parts all are housed in the insurance (5).

Antitheft principle of the present utility model is as follows: (referring to Fig. 1,2) will turn pipe valve axle (8) if having the people to look on the bright side of things to open pipe valve usurps the energy, make on the voussoir (19) and move.But the design covers pipe valve axle (8) with protecting casing (5).Be contained in the cross lock assembly (13) on the protecting casing (5), on dead bolt (15) be blocked in below the big cylindrical of filling tube (6), make protecting casing (5) can not on pipette down.Crash pad (3) is pressed on the pipe valve body (1), and is supporting protecting casing (5) by pipe valve lid (4), and protecting casing (5) can not be moved down.If attempt is turned on protecting casing (5) with instruments such as pipe wrench and is taken off, because of there is a throw of eccentric δ in the axle center of pipe valve lid (4) with the axle center of protecting casing (5); the torsion when twisting protecting casing (5) can make pipe valve lid (4); unclamp or come loose from pipe valve body (1); cause the fluid in the pipe valve body (1) to flow out, appropriator can stop its behavior at this moment at once.Be pressed in pipe valve gland (4), following crash pad (3) can prevent from directly to impact protecting casing (5) with external force.Antitheft principle of the present utility model that Here it is.

Be in advantage of the present utility model compared with the prior art:

1) adopted cross lock assembly (13) on the protecting casing (5), increased the insurance anti-theft capability, and volume has been little easy to use.

2) protecting casing (5) has an eccentric distance with the axis of crash pad (3), and is inserted in the crash pad (3).The shock resistance and the anti-ability of holding of protecting casing (5) have been improved like this.

3) when not being opened, directly rotate protecting casing (5) at cross lock assembly (13), because of outside the protecting casing (5) Decorative shell (16) is housed, and surface finishment is higher, can reduce the torsion that acts on the protecting casing (5).Only also have Decorative shell (16) is turned, and the protection effect that protecting casing is not turned produces.

4) if the released Δ angle of protecting casing (5), that will leak gas, leak, this is warning to appropriator, makes its termination usurp behavior.

Description of drawings:

Fig. 1: be orthogonal view of the present utility model.

Fig. 2: be the utility model figure one: the N-N sectional drawing.

Mode of execution of the present utility model is as follows:

The utility model is mounted in water supply or the heating system.The assembling method of pipe valve; The threaded end of pipe valve axle (8) is passed pipe valve lid (4), put crash pad (3),, be screwed in pipe valve axle (8) then with voussoir (19).On pipe valve body (1), put a pad (2), with the screw thread on the pipe valve lid (4) above-mentioned each part and pipe valve body (1) are linked together at last.Then, filling tube (6) is screwed on the pipe valve lid (4).Make voussoir (19), flexible motion in two wedge surface grooves at pipe valve body (1) under the rotation of pipe valve axle (8), good seal.Pad (2) can prevent that liquid etc. from leaking along the screw thread on the pipe valve body (1).For preventing that liquid etc. from flowing out along pipe valve axle (8), also be provided with filler (10), be filled in the filling tube (6) and be enclosed within on the pipe valve axle (8).Put filler gland (9) then, by gland (7), the axial force of generation also produces warp-wise power with filler (10) by the inclined-plane of filler gland (9) end face, fastens on the cylndrical surface of pipe valve axle (8), thereby reach good leakproof effect, all the other available sealer leakproofs in each screw thread place.

Cross lock assembly (13) is contained on the protecting casing (5), can keep off reliably under the big cylindrical on the filling tube (6) definite stretching out of dead bolt (15), dead bolt (15) withdrawal can be along taking off protecting casing (5) surely, with location lock (18), protecting casing (5) and cross lock housing (11) are locked together then.Make cross lock assembly (13), can not at will rotate and move.

Position shown in the accompanying

drawing

1,2 is that the utility model is in antitheft location status.If normal the use, when removing anti-theft state, its simple operations is as follows: with key last breach is aligned pit-mark on the cross lock assembly (13), insert the back and change 90 ° clockwise, then protecting casing (5) is gone up and extracted down, turn pipe valve axle (8), can operate pipe valve with spanner.If make pipe valve be in anti-theft state with protecting casing (5), align to press down by the throw of eccentric direction of crash pad (3) and guarantee that the bottom surface reliably contacts with crash pad (3), rotate counterclockwise key and transfer to key operated finishing for 90 °.
