Abstract
The invention discloses a kind of vacuum pipe length compensation device, including pipe joint, recessed flange and compensator flange, the opposite side end face of described recessed flange and compensator flange is each formed with the annular groove around central through hole, recessed flange opposite side end face connects pipeline, is provided with sealing gasket in the annular groove of recessed flange and compensator flange;Described pipe joint one end is welded with flange, and the other end stretches into the central through hole of compensator flange;One end of sleeve pipe is placed in the annular groove of pipe joint outside and insertion compensator flange, and the other end of sleeve pipe inserts in the annular groove of recessed flange, the sealing gasket in the equal hold-down ring connected in star in two ends of sleeve pipe;Bolt is each passed through the installing hole that recessed flange is corresponding with compensator flange, and fastens with nut.When the invention solves process pipe installation, the duct length that connects caused due to pipeline processing error changes the installation difficulty caused, thus ensureing the sealing requirements of junction.
Description
Technical field
The invention belongs to a kind of duct length compensation device, be specifically related to a kind of vacuum pipe length compensation device.
Background technology
In vacuum pipe is constructed, construct after good for pipe prefabrication in advance, it is possible to be greatly improved speed of application and construction quality.But in pipe prefabrication process, owing to there is mismachining tolerance and constantly accumulating, inevitably at certain pipeline junction, line size deviation occurs, two segment pipe length ratio design size length or short, all cause that two segment pipes can not normally connect.In this case on-the-spot can only change a social system pipeline, construction speed and construction quality are had impact.
Summary of the invention
The present invention proposes to overcome the shortcoming existed in prior art, its objective is to provide a kind of vacuum pipe length compensation device.
The technical scheme is that
A kind of vacuum pipe length compensation device, including pipe joint, recessed flange and compensator flange, the opposite side end face of described recessed flange and compensator flange is each formed with the annular groove around central through hole, recessed flange opposite side end face connects pipeline, is provided with sealing gasket in the annular groove of recessed flange and compensator flange;Described pipe joint one end is welded with flange, and the other end stretches into the central through hole of compensator flange;One end of sleeve pipe is placed in the annular groove of pipe joint outside and insertion compensator flange, and the other end of sleeve pipe inserts in the annular groove of recessed flange, the sealing gasket in the equal hold-down ring connected in star in two ends of sleeve pipe;Bolt is each passed through the installing hole that recessed flange is corresponding with compensator flange, and fastens with nut.
The annular groove shaped that described recessed flange is formed with a side end face of compensator flange is identical with size.
The width of described annular groove and the thickness of sleeve pipe match.
The invention has the beneficial effects as follows:
This invention address that when process pipe is installed, the duct length that connects caused due to pipeline processing error changes the installation difficulty caused, thus ensureing the sealing requirements of junction.Present configuration is simple, it is safe, easy to use to operate.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, vacuum pipe length compensation device of the present invention is described in detail:
As shown in Figure 1, a kind of vacuum pipe length compensation device, including pipe joint 1, recessed flange 2 and compensator flange 3, the opposite side end face of described recessed flange 2 and compensator flange 3 is each formed with the annular groove around central through hole, recessed flange 2 opposite side end face connects pipeline 6, is provided with sealing gasket 4 in the annular groove of recessed flange 2 and compensator flange 3;Described pipe joint 1 one end is welded with flange 10, and the other end stretches into the central through hole of compensator flange 3;The sleeve pipe 5 cylindrical shape in hollow, one end of sleeve pipe 5 is placed in the annular groove of pipe joint 1 outside and insertion compensator flange 3, and the other end of sleeve pipe 5 inserts in the annular groove of recessed flange 2, the sealing gasket 4 in the equal hold-down ring connected in star in two ends of sleeve pipe 5;Bolt 7 is each passed through recessed flange 2 and the corresponding installing hole 9 of compensator flange 3, and fastens with nut 8.
The annular groove shaped that described recessed flange 2 is formed with a side end face of compensator flange 3 is identical with size, and the thickness of the width of annular groove and sleeve pipe 5 matches.
The invention process comprises the following steps:
I. the preparation frock before installation
During () design pipeline, it is determined that place the position of compensation device: the present invention is installed on two segment pipes and connects closing place;
When () calculates line size, the line size placing place of the present invention is suitably reduced, in order to use the present invention to be adjusted;
(), according to pipe diameter, processes suitable vacuum pipe length compensation device;
II. the installation of vacuum pipe length compensation device
The pipe joint 1 being welded with flange 10 is connected by () with a segment pipe, is connected on the end face of another segment pipe 6 by recessed flange 2;
Compensator flange 3 is enclosed within pipe joint 1 by (), loads sealing gasket 4, be inserted into sleeve pipe 5 in annular groove, and sealing gasket 4 is pressed in the annular groove of compensator flange 3 by sleeve pipe 5, reaches vacuum and seals;
() places a sealing gasket 4 in recessed flange 2;
Recessed flange 2 to good, is welded on pipeline 6 by () by two two segment pipes to be connected, then adjusts compensator flange 3 and sleeve pipe 5, makes sleeve pipe 5 other end compress the sealing gasket 4 in the annular groove of recessed flange 2;
Bolt 7 is inserted in the installing hole 9 of recessed flange 2 and compensator flange 3 by (), clamp nut 8, makes one end of sleeve pipe 5 compress the sealing gasket 4 in compensator flange 3, and the other end compresses the sealing gasket 4 in recessed flange 2, installation.
