Abstract
The utility model relates to a device of oil development especially relates to a novel tubing coupling. Novel tubing coupling, including the coupling body, coupling body inner wall sets up tapered thread, coupling body outer wall is opened there is the promotion groove, and tapered thread adopts BU type tensile buttress thread. The utility model discloses an it is strong that knot nature is recognized to BU type tensile buttress thread, screw thread, transfers and can not damage the screw thread, and thread sealing extrusion atress be a direction, has changed the two -way extrusion atress of round thread, can not the thread making, can not the thread gluing, and prolonged life, promote the groove and make tubing coupling directly promote, workman's intensity of labour when having alleviateed the operation of promotion oil pipe.
Description
Technical field
The utility model relates to a kind of device for oil production, particularly relates to a kind of oil pipe and connects hoop.
Background technology
Tubing joint is in oil development, the mechanical part that petroleum oil connects, and is mainly used in the connection of oil pipe. The effects such as connected pipes is played in tubing joint, bears tension, promotes oil pipe, sealing pipe wire button. Tubing joint is in oil development, the mechanical part that petroleum oil connects, and is mainly used in the connection of oil pipe. The effects such as connected pipes is played in tubing joint, bears tension, promotes oil pipe, sealing pipe wire button. At present, tubing joint adopts API standard to connect hoop, and API specification tubing joint exists following problem: round thread silk button is 30 �� of angles, oil pipe bearing load big or connect hoop tired after, slippage accident easily occurs, and damage easy to wear detained by silk; Two elevators must being used when promoting oil pipe operation to replace and promote oil pipe, two workmans manually to lift and put elevator, dislodging elevator labour intensity is big.
Summary of the invention
The purpose of this utility model is to provide a kind of structure simple, it may also be useful to the life-span is long, and the oil pipe that can effectively alleviate labor strength during operation connects hoop.
The technical solution of the utility model is:
Oil pipe connects hoop, comprises and connects hoop body, connect hoop inner body wall tapered thread is set, described in connect hoop body outer wall have upgrading slot, tapered thread adopt BU type tension sawtooth screw thread.
Described screw thread specification is designed to per inch 8 tooth, pitch 3.175mm.
Described screw thread loading end is 3 ��.
It is 0.583mm that described screw thread disappearance position increases the dental impression degree of depth.
The utility model adopts BU type tension sawtooth screw thread, it is strong that silk button recognizes button property, transfer and can not damage silk button, thread seal extruding is a direction by power, changes the two-way extruding of round thread and is subject to power, can not thread making, can not thread gluing, extending work-ing life, upgrading slot makes tubing joint directly promote, and alleviates the labour intensity of workman when promoting oil pipe operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 connects hoop body 2BU type tension sawtooth screw thread 3 upgrading slot.
Embodiment
Oil pipe connects hoop, comprises and connects hoop body 1, connects hoop body 1 outer wall and has upgrading slot 3, tubing joint can directly be promoted, alleviate the labour intensity of workman when promoting oil pipe operation.
Connect hoop body 1 inwall and tapered thread be set, tapered thread adopt 2, BU type tension sawtooth screw thread 2, BU type tension sawtooth screw thread to buckle to recognize button property strong, transferring and can not damage silk button, sealed extruded is a direction by power, changes the two-way extruding of round thread by power, can not thread making, can not thread gluing;Screw thread specification is designed to per inch 8 tooth, pitch 3.175mm, and screw thread loading end is 3 ��, and silk button supporting capacity increases, can not slippage; It is 0.583mm that screw thread disappearance position increases the dental impression degree of depth, and the pull resistance of oil pipe body strengthens.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although being described in detail by the utility model with reference to better embodiment, those of ordinary skill in the field are it is understood that still can modify to embodiment of the present utility model or part technology feature carries out equivalent replacement; And do not depart from the spirit of technical solutions of the utility model, in the middle of its technical scheme scope that all should be encompassed in the utility model request protection.
