Abstract
The utility model belongs to the technical field of oilfield anti-theft equipment and particularly provides an anti-theft device for a production well, which comprises a pipeline valve. The pipeline valve is connected with a pipeline through a hoop. The pipeline valve comprises a valve body. The valve stem of the valve body is provided with a protection case body. The protection case body is provided with a switch case door. The switch case door and the sidewall of the protection case body are enclosed by an anti-theft lock. The anti-theft lock comprises a lock body and a lock pin positioned in the lock body. A return spring is sleeved outside the lock pin. The tail end of the lock pin is provided with a lock button. The lock button is provided with a strong magnet matched with the lock button. The outer surface of the strong magnet is in flush with the lock body. Due to the adoption of the above technical scheme of the utility model, a double-insurance mechanism is additionally arranged. Meanwhile, the device is simple in structure.
Description
Technical field
The utility model belongs to the technical field of oil field anti-theft device, specifically a kind of producing well anti-theft device.
Background technology
In oil recovery field; some lawless persons often steal crude oil or other oil recovery products accordingly; often at well head conduit fittings; by opening valve or destroying pipeline or steal from pipeline junction, cause the passage of national resources, for the problem of theft; also there are some anti-theft measures; as valve passed through to the airtight protections of mode such as welding, device for cleaning pipeline is crossed the airtight protection of the modes such as welding, brings thus in the time needing repairing or normally use and makes troubles.
Summary of the invention
The technical problems to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of be convenient to open and use producing well anti-theft device, employing comprises pipeline valve, described pipeline valve is connected with pipeline by clip, described pipeline valve comprises valve body, the valve rod of described valve body is provided with protection casing, this protection casing is provided with switch chamber door, described switch chamber door and sidewall seal by theftproof lock, described theftproof lock comprises lock body and is positioned at the lock pin of lock body, be set in the back-moving spring outside lock pin, described lock pin tail end is cage knob, this cage knob is provided with the kicker magnet matching, the technical scheme that the external surface of described kicker magnet flushes with lock body, increase double insurance, and simple in structure.
This programme is achieved by the following technical measures: a kind of producing well anti-theft device, it comprises pipeline valve, described pipeline valve is connected with pipeline by clip, described pipeline valve comprises valve body, the valve rod of described valve body is provided with protection casing, this protection casing is provided with switch chamber door, described switch chamber door and sidewall seal by theftproof lock, described theftproof lock comprises lock body and is positioned at the lock pin of lock body, be set in the back-moving spring outside lock pin, described lock pin tail end is cage knob, this cage knob is provided with the kicker magnet matching, the external surface of described kicker magnet flushes with lock body.
Described protection casing is welded on valve body.
Described valve rod is circular, and is combined with kicker magnet.
Described valve rod is pentagon, and is combined with kicker magnet.
Described valve rod is heptagon, and is combined with kicker magnet.
Described protection casing adopts the steel plate of hardness higher than HRC70.
The beneficial effect of this programme is: valve rod is protected with protection casing; and on switch chamber door, theftproof lock being set, this theftproof lock adopts the surface of kicker magnet to flush with lock body, is not easy to observe; more be not easy to destructive unlatching; need special tool just can open smoothly, in addition, the shape of valve rod is set to unconventional shape; even if open casing; do not have special tool cannot open valve yet, increased double insurance, and simple in structure.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
