Abstract
It is related to a kind of high pressure union attachment device of oil field drilling workover rig attachment device, its public union connector is connected in female union's connector, annular seal space in female union's connector is arc-shaped, outside is screw thread, the internal thread of wing nut one end and the external screw thread of female union's connector screw, and the other end of wing nut is contact of incline plane with fan-shaped baffle ring, fan-shaped baffle ring and public union connector.The utility model can realize sealing high-pressure fluid, increase female union's joint sealing cavity wall thickness, improve the bearing capacity and fatigue strength of union, extend service life.
Description
Technical field
The utility model is related to oil field drilling and repairing machine machine equipment attachment devices.
Technical background
Domestic common high pressure union is Weco forms at present, and comparative maturity in structure and in technique is widely used.Its
Female union's joint sealing chamber has annular groove, the shaft shoulder angle of wing nut and fan-shaped baffle ring, fan-shaped baffle ring and public union junction contacts
It it is 90 °, under high-pressure fluid effect, stress is concentrated the most.Meanwhile working environment also in the presence of vibration, particle wash away etc. because
Element more exacerbates the stress concentration of shaft shoulder contact portion, once failure, consequence are extremely serious.
The content of the invention
The purpose of this utility model is to propose a kind of novel high-pressure union attachment device, solves current high pressure union intensity not
The problem of enough.
To achieve the above object, the technical solution of the utility model is：
A kind of high pressure union attachment device, including male union connector 1, fan-shaped baffle ring 2, circlip 3, wing nut 4, mother
Union connector 5, union sealing ring 6, the outside of public union connector 1 is there are one fan-shaped baffle ring 2, flexible baffle ring on fan-shaped baffle ring 2
3, public union connector 1 is in female union's connector 5, and there are one union sealing ring 6, the wings between public union connector 1 and female union's connector 5
Shape nut 4 is connected on female union's connector 5 and fan-shaped baffle ring 2, it is characterized in that：Annular seal space in female union's connector 5 is
Arc-shaped, outside is equipped with screw thread, and union sealing ring 6 is matched arc-shaped with its annular seal space, and the axis fan of public union connector 1 is oblique
Shape, the inner shaft fan of fan-shaped baffle ring 2 be match with public 1 axis of union connector fan it is oblique, the outer shaft shoulder of fan-shaped baffle ring 2 be it is oblique,
One end in wing nut 4 is to match with the oblique of the outer shaft shoulder of fan-shaped baffle ring 2, screw thread and the female union's connector 5 of the other end
External screw thread matching.
Compared with prior art, the beneficial effects of the utility model are：
The utility model effectively reduces female union's joint sealing chamber, the public union connector shaft shoulder, wing nut root, baffle ring
Stress concentration, increase the wall thickness of female union's joint sealing chamber, improve the integrated carrying performance of high pressure union, improve peace
Quan Xing extends service life.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the high pressure union structure diagram of background technology.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Attached drawing 1, a kind of novel high-pressure union attachment device described in the utility model, including public union connector 1, sector
Baffle ring 2, circlip 3, wing nut 4, female union's connector 5, union sealing ring 6；During assembling, first by circlip 3, wing spiral shell
The outer circle that mother 4 puts on male union connector 1 successively respectively, then by fan-shaped baffle ring 2 from the gap of wing nut 4 and public union connector 1
Circlip 3, is finally packed into the groove of fan-shaped baffle ring 2 by middle loading, and union sealing ring 6 is packed into the close of female union's connector 5
Seal intracavitary.Public union connector 1 is connected with female union connector 5, and the internal thread of wing nut 4 is revolved with the external screw thread of female union's connector 5
Close, by hammering the lug of wing nut 4, the inclined-plane of female union's connector 5 and the sphere-contact of public union connector 1 position, it is public by
The end face of nonyl connector 1 compresses union sealing ring 6, realizes the function of sealing high-pressure fluid.
The annular seal space of female union's connector 5 is using no annular groove（Groove）Design, and the internal diameter of sealing surface is reduced, add wall
It is thick；Wing nut 4 is contact of incline plane with fan-shaped baffle ring 2, fan-shaped baffle ring 2 and public union connector 1.This design reduces female unions
The stress concentration of connector 5 and public union connector 1, increases the bearing capacity of entire union, improves fatigue strength, extending makes
Use the service life.
