Description
Technical field
The utility model is related to a kind of attachment devices for the pipeline joint being suitable for two eccentric axis.
Background technology
In engineering practice, when two pipeline joints are installed, eccentric axis problem can inevitably occur for pipeline joint, and pipeline is made to connect
Difficulty is connect, joint quality is influenced.The time and economic cost loss that school shape or processing generate are larger.The long tube of pipe with small pipe diameter is docked at
Still correction connection in the case that deviation is little, but in the case where caliber is larger, docking length of tube is shorter, if docking
Deviation is difficult then correction connection.This device fully solves problem above, even more realizes suitable with Smallest connection contour structures
The pipeline eccentric axis of bigger is answered to misplace, the pipeline deviation of permission is larger.Its overall structure is simple and convenient to operate, eccentric
The scope of application maximum of amount up to the sum of the eccentricity of eccentric nipple and eccentric coupling, significantly reduce installation cost and
Time is suitable for solving the docking pipeline eccentric axis installation question of various calibers.
Invention content
The purpose of this utility model is to disclose a kind of pipeline eccentric coupling device, by fastening pressure ring, eccentric coupling, bias
Nipple, gasket, the first pipeline and the second pipeline composition, first the first pipeline and the second pipeline are respectively welded fixed to bias
In coupling and eccentric nipple, then gasket is put into inside eccentric coupling, eccentric nipple is inserted in eccentric external
In head, by the relative rotation of eccentric coupling and eccentric nipple, the first pipeline and the second pipeline axis relative eccentric are adjusted
Amount, the pipeline pair for making the external axis axis offset that the first pipeline of welding and the second pipeline are connect with them respectively misplace
Standard, and be connected on external pipeline by pipe joint, then utilize fastening pressure ring by eccentric coupling and eccentric nipple
It compresses, and is sealed using gasket, to realize the adaptation and connection of the pipeline of two eccentric axis.
The pipeline eccentric coupling device, the first pipeline is inserted into eccentric coupling, and uses and be welded to connect with it, and first
Pipeline is parallel with eccentric coupling axis and eccentric axis, eccentric coupling outer wall have external screw thread.
The pipeline eccentric coupling device, the second pipeline is inserted into eccentric nipple, and uses and be welded to connect with it, and second
Pipeline is parallel with eccentric nipple axis and eccentric axis, the outer diameter of eccentric nipple are less than the internal diameter of eccentric coupling.
The utility model has the beneficial effects that：
In engineering practice, when two pipeline joints are installed, eccentric axis problem can inevitably occur for pipeline joint, and pipeline is made to connect
Difficulty is connect, joint quality is influenced.This pipeline eccentric coupling device is adjusted by the relative rotation of eccentric coupling and eccentric nipple
It is inclined to adjust the external axis axis for making the pipeline of welding be connect respectively with them after good position for homogeneous tube road axis relative eccentric amount
Move the pipeline alignment of dislocation, and be connected on external pipeline by connector, then using fastening pressure ring by eccentric coupling with
Eccentric nipple compresses, and is sealed using gasket.
This unique coupling of pipeline eccentric coupling device, the design of nipple eccentric position, realize with outside Smallest connection
The pipeline eccentric axis of shape Structure adaptation bigger misplaces, and the pipeline deviation of permission is larger, caliber is larger, docking length of tube compared with
Advantage is especially pronounced in the case of short, and overall structure is simple and convenient to operate, and the scope of application maximum of eccentricity is up to eccentric
The sum of the eccentricity of nipple and eccentric coupling, significantly reduces installation cost and time, is suitable for solving various calibers
Docking pipeline eccentric axis installation question.
