Abstract
The utility model relates to the technical field of anti-theft devices, in particular to an anti-theft device of a valve for an oil well oil extraction well mouth and an oil storage tank oil outlet. The anti-theft device of the valve mainly consists of a valve body, a conical valve core, a round locking disc and a lead screw, wherein the valve body is fixed inside the conical valve core, and a locking sleeve and a gate cover plate are sequentially welded at the upper portion of the valve body. The bottom end of the lead screw is of a square structure and connected with the conical valve core, the top end of the lead screw is of a pentagonal structure, and a larger spring, a lower bush, the round locking disc and an upper bush sleeve the upper portion of the lead screw sequentially. The anti-theft device of the valve has the advantages that a small spring is different from a locking column in size, the anti-theft device is used by being matched with a disc-shaped unlocking device arranged above the gate cover plate, and good anti-theft effect is played on valves of a well mouth and an oil delivery pipe.
Description
Technical field
The utility model relates to anti-theft device technical field, specifically, relates to a kind of valve anti-theft device for oil extraction in oil field well head, oil storage tank oil outlet.
Background technique
At present, valve is the requisite devices such as oil extraction in oil field well head, oil storage tank oil outlet, petroleum pipeline gate valve control point, in order to block or to adjust the flow of fluid in pipeline, a lot of oily spool line installation paths is long, scope is larger, large-scale oil field particularly, the oil field area that cause relates to is larger, keep an eye on anti-theft measure inadequate, the stolen phenomenon of crude oil at the gate valve control point of the oil outlet of production wellhead, oil storage tank, petroleum pipeline happens occasionally, bring to the normal production in oil field and work and have a strong impact on, and may bring huge economic loss.
Model utility content
The purpose of this utility model is the shortcoming existing for existing oil field wellhead theftproof device, and a kind of valve anti-theft device with stronger anti-theft feature is provided.
The technical solution of the utility model is: a kind of valve anti-theft device, is characterized in that: mainly valve body, taper valve core, circular lock collar and leading screw, consist of, described valve body is fixed on the inside of taper valve core, and valve body top is welded with lock tube and gate cover plate successively; Leading screw bottom is square structure and is connected with taper valve core, and top is pentagonal configuration, and leading screw top is overlapped successively big spring, lower lining, circular lock collar and upper lining.
Preferably, be evenly equipped with four square grooves in described circular lock collar, a lock that size is different is all equipped with on each square groove top, and the bottom of each lock is provided with a little spring that size is different.
Preferably, be evenly equipped with four square grooves on described lock tube, lock is built in four square grooves of lock tube, between lock and lock tube, is provided with circular port.
Preferably, described gate cover plate top is also provided with disc tripper, and this device is laid with four pillars that length is different, and pillar can vertically insert circular port inside.
Preferably, described circular lock collar is positioned at the centre of lining and lower lining, and upper lining supports circular lock collar, and lower lining compresses circular lock collar.
The utility model beneficial effect is compared with prior art:
Valve anti-theft device of the present utility model, be installed on the valve place of well head and transport pipe, mainly by valve body, taper valve core, circular lock collar and leading screw, formed, and because of little spring different with lock size, if do not used disc tripper, thief is difficult to Open valve, must be used in conjunction with the disc tripper that gate cover plate top is provided with, and the valve of well head and transport pipe is reached to good antitheft object.
Accompanying drawing explanation

Fig. 2 is the structural representation of the utility model tripper.
In figure, 1-taper valve core, 2-valve body, 3-big spring, 4-little spring, 5-lower lining, 6-circular lock collar, 7-lock, 8-upper lining, 9-lock tube, 10-gate cover plate, 11-tripper, 12-leading screw, 13-spanner
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
Referring to Fig. 1, Fig. 2, a kind of valve anti-theft device, is mainly comprised of valve body 2, taper valve core 1, circular lock collar 6 and leading screw 12, and valve body 2 is fixed on the inside of taper valve core 1, and valve body 2 tops are welded with lock tube 9 and gate cover plate 10 successively; Leading screw 12 bottoms are square structure and are connected with taper valve core 1, and top is pentagonal configuration, and leading screw 12 tops are overlapped successively big spring 3, lower lining 5, circular lock collar 6 and upper lining 8.
In circular lock collar 6, be evenly equipped with four square grooves, a lock 7 that size is different is all equipped with on each square groove top, and the bottom of each lock 7 is provided with a little spring 4 that size is different.
On lock tube 9, be evenly equipped with four square grooves, lock 7 is built in four square grooves of lock tube 9, and 9 of lock 7 and lock tubes are provided with circular port.
Gate cover plate 10 tops are also provided with disc tripper 11, and this device is laid with four pillars that length is different, and it is inner that pillar can vertically insert the circular port of 9 of lock 7 and lock tubes.
Circular lock collar 6 is positioned at the centre of lining 8 and lower lining 5, and upper lining 8 supports circular lock collar 6, and lower lining 5 compresses circular lock collar 6.
During release, aim at tripper 11 and gate cover plate 10, the different pillar of four length of tripper 11 is vertically inserted to the circular port inside of lock 7 and 9 of lock tubes, press down the little spring 4 of the bottom of lock 7 simultaneously, make each lock 7 upper end height consistent, and consistent with the position of circular lock collar 6.Meanwhile, by spanner 13, by rotating threaded shaft 12 and circular lock collar 6, drive taper valve core 1 to rotate, thereby realize the opening and closing of valve.
