The structure comprises a fixed pressure plate, a lock switch assembly and a guide shaft sleeve of an unlock mechanism; wherein the fixed pressure plate is mounted on a bracket of a gate valve, a rotary screw nut for opening the gate valve is provided in the bracket of the gate valve, a through hole is provided on the side surface of the fixed pressure plate, the lock switch assembly is mounted on the side surface of the fixed pressure plate, the central hole of the lock switch assembly is communicated with the through hole on the side surface of the fixed pressure plate, and a guide shaft sleeve of the unlock mechanism is welded on the lock switch assembly to be vertical to the lock switch assembly. Compared with the prior art, the antitheft bar-code magnetic-control lock mounted on gate valve support in oilfield for preventing crude oil from being stolen, the utility model has the advantages of rational design, convenient application and safe and reliable operation, etc.
Description
Technical field
The utility model relates to a kind of magnetic control lockset, specifically a kind of oil field oil recovery crude oil theft-proof gate valve support bar code magnetic control lock that is used for.
Background technology
The gate valve of draining the oil of each individual well oil tank of oil field all is installed in the open, and the present anti-theft measure of taking mainly contains methods such as locking-type on the chain, labyrinth theft-proof type, magnetic tension theft-proof type.Mainly there is following problem in these several antitheft modes: 1), the locking-type anti-theft device is simple in structure, easy to operate, with low cost on the chain, but be easy to be destroyed by the lawless person, belong to symbolic antitheftly, theftproof performance is general; 2), labyrinth type anti-theft device complex structure, complex operation, the difficulty of unblanking when viscosity of crude reduces in the winter time, anti-theft effect is also undesirable; 3), magnetic tension formula anti-theft device complex structure, use cost height, good anti-theft effect, but the mode heaviness of unblanking.The antitheft problem of the solution gate valve that several modes all can not be desirable therefore.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of rational in infrastructure, safe and reliable oil field oil recovery crude oil theft-proof gate valve support bar code magnetic control lock that is used for is provided.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises fixed platen, lock-switch assembly and unlocking mechanism guideway, fixed platen is fixed on the gate valve support, the swivel nut of opening gate valve is arranged in the middle of the gate valve support, the side of fixed platen has through hole, the lock-switch assembly is fixed on the side of fixed platen, and its centre bore communicates with the side perforate of fixed platen, is welded with the unlocking mechanism guideway perpendicular to the lock-switch assembly;
The lock-switch assembly comprises locking rod, lock pin, the lockable mechanism guideway, guard shield, magnetic padlock head and return spring, the arranged outside of lockable mechanism guideway has guard shield, be provided with locking rod in the side perforate of the centre bore of lockable mechanism guideway and fixed platen, cover is by return spring on the locking rod, tail end one side of locking rod is provided with lock pin, one side of the corresponding unlocking mechanism guideway of lockable mechanism guideway has the locating hole of unblanking, be provided with in the unlocking mechanism guideway and the corresponding magnetic padlock head of the locating hole of unblanking, the front end of unlocking mechanism guideway is provided with the key backplate of unblanking.
Unblank to be provided with between locating hole and the locking rod lockable mechanism shell fragment; The magnetic padlock head also joins with the unlocking mechanism shell fragment that is fixed in the guard shield.
When gate valve support theftproof lock needs locking, promote locking rod, overcome return spring tension force and move forward, pin the gate valve swivel nut, gate valve can not be opened, prevent stolen by external force; Key inserts guideway and rotates to an angle when unblanking, and is relative with N, S the two poles of the earth same sex on the magnetic padlock head when on the key N, S the two poles of the earth, when reaching maximum repulsive force, overcome the resistance of lockable mechanism, under return spring tension force, promote locking rod and reset, lockable mechanism is unblanked, and gate valve is opened and is drained the oil; Mainly be the magnetic control technology that has adopted various combination, set unlocking function, be difficult for copying, high security performance is provided.
Of the present utility modelly be used for oil field oil recovery crude oil theft-proof gate valve support bar code magnetic control lock oil stealer when complete locking and can not open gate valve and drain the oil; Can prevent when opening locking that the stranger from closing gate valve.The lock core of unblanking is a column type, and key is a column type also, and lockhole is not afraid of destroyed, and it is convenient and swift to unblank.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
