Abstract
The utility model relates to a mechanical pumping wellhead device, in particular to a theftproof device for oil well. The utility model adopts the technical proposal that the device comprises a connector, a terminal area and a pressure converting shaft; wherein a through hole is arranged at the bottom of the connector and the top of the connector is connected with the terminal area; the pressure converting shaft is a T-type and connected with the flange in interference fit; a sealing ring is arranged between the pressure converting shaft and the terminal area. The utility model has the advantages of small volume, simple structure and low production cost, thus increasing the working efficiency, effectively preventing the oil well theft outdoors and avoiding the source waste.
Description
One, technical field:
The utility model relates to a kind of mechanical oil well wellhead assembly, particularly relates to a kind of oil well anti-theft device.
Two, background technology:
Production tree in the oil field oil water manufacturing process mainly is made up of the oil of sleeve pipe big four, tubing hanger, the little four-way of oil pipe and both wings, sleeve gate, clip bolt, polished rod seal box etc.Owing to when this wellhead assembly of design, only considered high voltage bearing requirement, do not consider antitheft problem, thereby become the lawless person to steal the main position that oil destruction is set about.The way of Xie Jueing is to buckle a Pithead preventing thieves room of making of cement or steel plate to every mouthful of well for this reason, and whole wellhead assembly is buckled in the inside entirely, but the problem that exists is: cost is too high, and influences work of maintenance personnel efficient.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide a kind of can effectively prevent the lawless person steal oil, cheaply, make simple oil well anti-theft device.
Its technical scheme is: comprise joint, terminal pad and pressure transaxle, wherein, the joint lower end is provided with through hole, the upper end is connected with terminal pad, described pressure transaxle is a T-shaped, and adopts interference fit with terminal pad, is provided with sealing ring between pressure transaxle and terminal pad.
The beneficial effects of the utility model are: volume is less, and simple in structure, cost is low, has simultaneously also improved work of maintenance personnel efficient, prevents that effectively open-air oil well is stolen, has avoided the wasting of resources.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is for comprising joint 1, terminal pad 3 and pressure transaxle 4, wherein, joint 1 lower end is provided with through hole 5, be used to the well head pressure that circulates, the upper end is connected with terminal pad 3, and described pressure transaxle 4 is a T-shaped, and adopt interference fit with terminal pad 3, between T-shaped pressure transaxle 4 and terminal pad 3, be provided with sealing ring 2, prevent the Oil, Water, Gas seepage, make anti-helmet sealing firmly.
During use, through hole 5 one ends of joint 1 are welded on well head, the endoporus of terminal pad 3 and pressure transaxle 4 adopt interference fit, and there is sealing ring 2 centre, can avoid oil, seepage, and crude oil, water flow into inner room from joint through hole 5, jack-up pressure transaxle 4.
Claims (1)
1, a kind of oil well anti-theft device, comprise joint, terminal pad and pressure transaxle, wherein, the joint lower end is provided with through hole, the upper end is connected with terminal pad, it is characterized in that: described pressure transaxle is T-shaped, and adopts interference fit with terminal pad, is provided with sealing ring between pressure transaxle and terminal pad.
