Abstract
The utility model discloses a two-stage burglarproof valve and relates to a burglarproof valve used on the oil field. Currently, the crude oil thieving problem in the oil field and well is serious, but the current normal burglarproof valve has the disadvantages of weak burglarproof performance and big investment. The utility model comprises a valve handle (1), a valve body (2) arranged at the outside of the valve handle (1), a bearing (3) arranged at the end of the valve body (2) and a copper sleeve (4) connected with the bearing (3); wherein, the copper sleeve (4) is screwed on the valve handle (1); a burglarproof device (5) having an H-longitudinal section is covered on the outer surface of the copper sleeve (4); a concave pulley (6) and a locking nut (7) are arranged in the hole (5-1) of the burglarproof device (5) in turn; the concave pulley (6) is connected with the copper sleeve (4) through a key (9); and the locking nut (7) is screwed on the copper sleeve (4). The valve provided by the utility model is modified from a normal valve and has the advantages of reducing the cost, easy modifying, easy production and operation, easy popularization in production, easy structure, low investment and easy application.
Description
Technical field: the utility model relates to a kind of valve for guarding against theft that uses on the oil field.
Background technique: at present, the stolen problem of oilfield crude oil is serious, and existing common valve for guarding against theft can not play the effect that prevents that crude oil is stolen, because the employed special tool of existing valve for guarding against theft is imitated easily, so still can be easy to valve open, a little less than its anti-theft capability, and investment is big; The way that take in the oil field that has is at well head theft-proof box to be installed, and the shortcoming that the theft-proof box existence is installed is 1, invests greatly, is not easy to popularize; 2, be not easy to production operation; 3, very easy destroyed.
The model utility content: the purpose of this utility model is to provide a kind of good anti-theft effect, repacking to be easy to the two-stage valve for guarding against theft, it comprises valve rod 1, is arranged on the valve body 2 of valve rod 1 outer end, in the end of valve body 2 bearing 3 is set, bearing 3 is connected with copper sheathing 4, described copper sheathing 4 and valve rod 1 are by being threaded, outer surface at copper sheathing 4 is with the alarm 5 that the longitudinal section is a H shape, in the 5-1 of the hole of alarm 5, be provided with concave type wheel 6 and locking nut 7 successively, concave type wheel 6 is connected with copper sheathing 4 by key 9, and locking nut 7 and copper sheathing 4 are by being threaded.The utility model has the two-stage anti-theft feature, with concave type wheel replacement handwheel in the past, the hole of alarm is bearing and copper sheathing, concave type wheel and locking nut all cover on inside, must could operate with special tool, play the antitheft effect of first layer, the spill wheel is connected with the copper sheathing key, has only by the groove fit on special tool and the concave type wheel and just can open valve, steal the people and can't open with general tool, realize second layer anti-theft feature, valve of the present utility model is to change a social system on the basis of common valve, only need to change handwheel and locking nut on the basis of common valve, and it is just passable that H shape alarm is installed, therefore, reduce cost of investment, be convenient to repacking, be convenient to production operation, popularize aborning easily, it is simple in structure, invests for a short time, is beneficial to and applies.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the structural representation of locking nut 7, and Fig. 4 is the left view of Fig. 3.Fig. 5 is the structural representation of embodiment two.
Embodiment one: with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, present embodiment comprises valve rod 1, be arranged on the valve body 2 of valve rod 1 outer end, in the end of valve body 2 bearing 3 is set, bearing 3 is connected with copper sheathing 4, described copper sheathing 4 and valve rod 1 are by being threaded, the outer surface of copper sheathing 4 is with the alarm 5 that the longitudinal section is a H shape, in the 5-1 of the hole of alarm 5, be provided with concave type wheel 6 and locking nut 7 successively, the outer surface of concave type wheel 6 is provided with at least three groove 6-1, the outer surface of locking nut 7 is provided with at least three groove 7-1, concave type wheel 6 is connected with copper sheathing 4 by key 9, locking nut 7 and copper sheathing 4 are by being threaded, and bearing 3 is arranged in another hole 5-2 of H shape alarm 5.
Operate valve of the present utility model, have only by pin on the special tool and the groove on the concave type wheel on the utility model 6 and match, could realize the switch of valve.The utility model replaces existing valve handle with concave type wheel, concave type wheel is provided with groove 6-1, circular arc is made at the edge of groove 6-1, different according to the change of the groove location on the concave type wheel and concave type wheel diameter, can make the different two-stage valve for guarding against theft of specification, thereby realize " opening different locks with different keys ", also can make " key is driven several locks " as required, it has overcome the shortcoming of common valve for guarding against theft " a special tool prodigiosin is opened all valves ", if the common valve special tool is stolen or the quilt imitated, so all common valve for guarding against theft will lose anti-theft feature, in addition, H shape alarm covers on its inside to concave type wheel, concave type wheel is designed to matrix, and the groove location difference of each concave type wheel, therefore can't prevent system, even certain special tool is stolen, as long as change with its supporting concave type wheel just passable, in addition, locking nut is also made matrix, principle is identical with concave type wheel, has only the special tool that cooperates this valve simultaneously to operate, otherwise can't pull down.
Embodiment two: with reference to Fig. 5, what present embodiment and embodiment one were different is that the alarm 5 usefulness U-shaped alarms 8 of H shape replace.
