Abstract
The utility model discloses a valve anti-theft device, and relates to a device used for guarding against a valve theft. The valve anti-theft device resolves the problems such as a valve loses effectiveness caused by the reasons that the used valves in the production and transportation process in the existing oil and gas field are poor in performances of anti-theft oil, easy to rust and the like. The device comprises a shield and a wrench, wherein the bottom of the shield is provided with a shield opening, and the shield body of the shield is provided with an opening opposite to a valve screw rod. The wrench comprises a handle and a rod, wherein the rod is provided with a mechanism which is matched with the valve screw rod. The valve anti-theft device has the advantages of being superior in anti-theft performance, compact in structure, easy to manufacture, convenient to use, time-saving, and labor-saving and the like. Besides, the device is mainly used for the valves of oil field conveying pipelines.
Description
Technical field
The utility model relates to a kind of anti-theft device, particularly a kind of device for safety valve.
Background technique
In the production of oil gas field, course of conveying, the undesirable is owing to economic benefits orders about, do not stint and defy the law, steal the oil gas energy, accumulate over a long period and caused great economic loss to country, oilfield enterprise, had a strong impact on safety in production and the conveying of petroleum resources.The valve of at present oil gas field use, mostly adopt locking flanged valve anti-theft device, and the valve major part of the christmas tree of oil gas field, technological process is installed in the field, wilderness, very easily suffers sabotaging of undesirable, in case locking part is smashed, cuts off, it has just lost anti-theft function.There is following shortcoming in the valving that now uses: the one, do not possess anti-theft feature, and the lawless person is easily stolen; The 2nd, with the valving of cipher lock often since the cipher lock core rust dead, damage or forget Password and cause valve switch motionless; The 3rd, bore little some valvings do not possess the function of antitheft anti-operation yet; The 4th, existing anti-theft device does not have versatility, is not suitable for various valve model.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiency that existing safety valve aspect exists, and provides a kind of reasonable in design and can improve the valve anti-theft device of above-mentioned shortcoming.
The purpose of this utility model can realize by following technical solution:
This valve anti-theft device comprises guard shield and spanner, and the bottom of described guard shield is provided with the cover mouth, and the cover body of described guard shield is provided with the opening relative with valve screw, and described spanner comprises handle and bar, and described bar is provided with the mechanism that matches with valve screw.The effect that the opening relative with valve screw is set at the cover body of described guard shield is the bar of described spanner and the mechanism that matches with valve screw on this bar can be inserted in the described guard shield dock with the screw mandrel of valve.The effect that the mechanism that matches with valve screw is set on the bar of described spanner is described spanner can be docked with valve screw and can drive screw mandrel to open valve.The effect of the bottom cover mouth of described guard shield is to make the cover body of described guard shield can be placed in the outside of valve by this cover mouth, by the mechanism of welding or be fixedly connected with the cover body of described guard shield and valve is achieved a fixed connection again.
The purpose of this utility model can also be opened realization by following technical solution:
On the cover body of described guard shield with the described spanner profile of the mechanism that matches with valve screw of the profile of the shape of opening and size and the bar of described spanner and size or this bar and big or small corresponding that matches.The corresponding effect of the profile of the profile of the opening shape that matches with described spanner on the cover body of described guard shield and size and the bar of described spanner and the mechanism that matches with valve screw of size or this bar and size be the bar that makes described spanner and this bar make described opening realize minimizing when the mechanism that matches with valve screw can insert described guard shield, improve described guard shield anti-theft capability and improve dust-proof effect being conducive to.Opening on the cover body of described guard shield is provided with dust cover.The effect of this dust cover is that dust cover seals described opening the valve part in the described guard shield is played the effects such as dustproof, rainproof at ordinary times, can open during to valve operation described spanner to be inserted in the described guard shield operate.The cover body bottom of described guard shield is provided with the mechanism that is fixedly connected with valve.The effect that the described mechanism that is fixedly connected with is set is to realize easy dismounting operation, convenient maintenance, repair to described guard shield and valve between the cover body of described guard shield and valve.The mechanism that the cover body bottom of described guard shield is fixedly connected with valve comprises set screw nut and fixing pin, and described set screw nut is fixedly connected with the cover body of described guard shield.The effect of described set screw nut and fixing pin is to realize the cover body of described guard shield and being fixedly connected with of valve by described set screw nut, further cover body and the valve of described guard shield is fixed and locates by described fixing pin.That the described mechanism that is fixedly connected with that comprises described set screw nut and fixing pin has is simple in structure, be convenient to make and the advantages such as installation.Be provided with movable axis between the cover body of described dust cover and described guard shield.Described movable axis effect is to make described dust cover and the cover body of described guard shield realize connecting and can moving relative to this cover body.Described movable axis is set has the convenient advantage of using described dust cover.
The beneficial effects of the utility model: owing on original valve, can by installing described guard shield additional, make described guard shield produce exterior protection and limit the effect of operating space valve, thereby described guard shield play the antitheft and protective action to valve; Owing to can on the bar of described spanner, with valve screw various mutual fitting mechanism be set, thereby can form the proprietary relation of being connected between described spanner and the valve screw, thereby described spanner controls valve and plays restriction effect, thereby effectively improved the theft protection of valve, the function of anti-operation; Because the described dust cover of design can make described guard shield effectively protect valve rod not to be subjected to the impact of dust storm and corrosion, has stopped unsafe factor dirty because of valve, that embroidery causes.So, the utlity model has that theftproof performance is superior, compact structure, be easy to make, easy to use, save time, the advantage such as laborsaving.
