Abstract

The invention provides a kind of production wellhead guard against theft oil stop valve.Mainly solve lawless person's problem easily by wellhead tree tree stolen.Described top, fuel-displaced tubing string, intermediate plate, oil-feed tubing string integration connect, and be provided with ball, oil-feed tubing string be provided with fuel feed hole, fuel-displaced tubing string is provided with oil outlet in oil-feed tubing string.Present configuration is simple, installs hidden, good anti-theft effect, and is not easy to be destroyed.

Description

Production wellhead guard against theft oil stop valve
Technical field
The present invention relates to oil production equipment field, a kind of production wellhead guard against theft oil stop valve preventing stolen.
Background technology
Oil field equipment includes down-hole oil production environment division and aboveground oil production equipment, the core component of underground equipment part Being exactly oil pumper, uphole equipment part is mainly made up of production tree, and its effect is oil gas down-hole oil production equipment collection come up Resource is allocated transmission, and equipment is arranged on field and is easily destroyed pilferage by lawless person, and underground equipment cannot directly contact, institute Aboveground oil production equipment part would generally be selected to steal with the lawless person of stolen, as well-surface part production tree head when it Punching, the most only i.e. need to can realize oil behavior steathily, or produce pipe at production wellhead with the valve that pipe is connected on production tree Line valve output outer end punching connects pipeline and steals, and brings about great losses to country's petroleum resources, destroys oil field simultaneously Equipment, and and it is likely to result in the pollution of environment.
Summary of the invention
For solving problem present in background technology, the invention provides one and be arranged in production wellhead flow line Portion, the production wellhead guard against theft oil stop valve that guard against theft oil function is outstanding.
Technical scheme: a kind of production wellhead guard against theft oil stop valve, including top, fuel-displaced tubing string, intermediate plate, oil-feed tubing string, rolling Pearl, described top, fuel-displaced tubing string, intermediate plate, oil-feed tubing string integration connect, and are provided with ball, oil-feed tubing string in oil-feed tubing string On be provided with fuel feed hole, fuel-displaced tubing string is provided with oil outlet;
Further, described top is circular arc;
Further, described intermediate plate is provided with the steam vent that at least three is uniformly arranged;
Beneficial effect: by using technical scheme, device integral installation, on production wellhead, is difficult to find and do not allow The most destroyed, overall structure is simple, good anti-theft effect.
Accompanying drawing explanation
Fig. 1 is organigram of the present invention.
Fig. 2 is structural section of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
By a kind of production wellhead guard against theft oil stop valve shown in Fig. 1, Fig. 2, including coming directly towards 1, fuel-displaced tubing string 2, intermediate plate 3, enter Tubing string 4, ball 5, described top 1, fuel-displaced tubing string 2, intermediate plate 3, oil-feed tubing string 4 integration connect, and install in oil-feed tubing string 4 There is ball 5, oil-feed tubing string 4 is provided with fuel feed hole, fuel-displaced tubing string 2 is provided with oil outlet;
As one embodiment of the present of invention, described top 1 is circular arc, and circular arc top uses alloy material, and hardness is high, The when that stolen molecule destroying equipment, circular arc top can prevent stolen molecule from being destroyed by electric drill boring.
As one embodiment of the present of invention, described intermediate plate 3 is provided with the steam vent that at least three is uniformly arranged, protects Demonstrate,prove after ball 5 is by oil transportation hole closure on intermediate plate 3, also can be exhausted pressure release work.
Concrete, this device is arranged on production wellhead, is fixed by intermediate plate 3 by the ring flange on flow line, just In normal oil transportation work, pressure balance, ball does not block the oil transportation hole on ring flange, when periphery petroleum pipeline is punched by lawless person During stolen, pressure reduction increases, and ball 5 moves and blocked in oil transportation hole, is cut off, and flowline stops fuel-displaced, and outside having concurrently simultaneously and preventing Enclose the function of pipe leakage.
Although above it has been shown and described that embodiments of the invention, it is to be understood that above-described embodiment is example Property, it is impossible to be interpreted as limitation of the present invention, those of ordinary skill in the art is without departing from the principle of the present invention and objective In the case of above-described embodiment can be changed within the scope of the invention, revise, replace and modification.
