Abstract
Proposed by the present invention is a kind of adjusting bellows installing/dismounting method.Upward adjustment screw and lower adjustment screw are connected with by adjustable nut between lower dental lamina and upper dental lamina；Three groups of installing and dismounting bars are interconnected by chain.By the spacing for measuring lower flange on bellows pipeline to be installed; the effective adjusting bellows protection installing and dismounting bar of ripple to be installed is formed into 120 degree of encirclements; bellows compression is carried out according to the spacing measured, compressed bellows is put into position step to be installed carries out.The present invention is using three groups of installing and dismounting bar group linkages and the adjustment of positive/negative thread nut so that bellows, by adjusting the length of bellows, avoids damaging due to unbalance stress during installation, dismounting, reaches Fast Installation and dismounting.It is simple in structure, convenient and efficient.Suitable for as a kind of adjusting bellows installing/dismounting method application.
Description
Technical field
The present invention relates to the installation and dismounting of the bellows of various specifications, especially suitable for the wave on the vapor system of high temperature
Line pipe.Specifically a kind of adjusting bellows installing/dismounting method.
Background technology
The installation of bellows for a long time is a very intractable job, and the bellows of manufacture carries independent packaging.Installation
Before the dismantle bellows of independent packaging can extend under tension very much, and when installing bellows need to compress a part it is long
The force compresses such as degree could enter flange interstitial site, and what very important person was to prevent bellows from damaging, before installation carries out, will be compressed
Bellows is put into the position in flange gap, penetrates bolt after the screw hole alignment of upper lower flange, could slowly unclamp, this is peace
The a big difficulty of dress；In addition dismounting sets the bellows on each and pipeline, due to no matched extracting tool, is dismantling
Bellows takes out moment generation elastic deformation from flange gap and is easily damaged, reason due to being acted on by elastic force in journey
It is the bellows slow release useless for carrying out elastic force.No matter damage caused by installation or dismounting, economic loss is not small, value
More than thousands of members to tens of thousands of members, or even hundreds of thousands member.
Invention content
In order to enable bellows can adjust the length of bellows in installing and dismounting, the present invention proposes a kind of adjustable
Bellows installing/dismounting method.This method is adjusted by three groups of installing and dismounting bar group linkages and positive/negative thread nut, solves ripple
The technical issues of pipe is installed with dismounting.
Scheme is used by the present invention solves technical problem：
Installing and dismounting rod structure：Upward adjustment screw and lower adjustment are connected with by adjustable nut between lower dental lamina and upper dental lamina
Screw rod；
Three groups of installing and dismounting bars are interconnected by chain.
The adjustable nut both ends carry plus thread and left-hand thread.
The upper adjustment bar carries left-hand thread.
The lower adjustment bar carries plus thread.
A kind of adjusting bellows installing/dismounting method：
1st, the spacing of lower flange on bellows pipeline to be installed is measured, while this spacing adds the thickness of upper and lower two gaskets
Degree.
2nd, the effective adjusting bellows protection installing and dismounting bar of ripple to be installed is formed into 120 degree of encirclements, locking is adjustable
Whole nut.
3rd, bellows compression is carried out according to the spacing measured, is measured simultaneously in compression process and keep the flat of lower flange
Row degree, decrement are more than the spacing measured and the gasket amount of flange.
4th, compressed bellows is put into position to be installed, makes the flange eye of bellows and the flange eye of upper lower flange right
Installation bolt after just.Adjustable nut is slowly unclamped, lays down ripple protection of pipe installing and dismounting bar group.
Good effect, since the present invention is using three groups of installing and dismounting bar group linkages and the adjustment of positive/negative thread nut so that wave
Line pipe by adjusting the length of bellows, is avoided being damaged due to unbalance stress, reaches quick during installation, dismounting
Installation and dismounting.It is simple in structure, convenient and efficient.Suitable for as a kind of adjusting bellows installing/dismounting method application.
Description of the drawings
Fig. 1 is structure composition schematic diagram of the present invention；
Fig. 2 is adjustable nut sectional view of the present invention；

In figure, dental lamina on 1. adjusts bar, 3. adjustable nuts, 4. times adjustment bars, 5. times dental laminas, 6. chains on 2..
Specific embodiment
According to the figure, installing and dismounting rod structure：It is connected between lower dental lamina 5 and upper dental lamina 1 by adjustable nut 3
Adjustment screw 2 and lower adjustment screw 4；
Three groups of installing and dismounting bars are interconnected by chain 6.
The adjustable nut both ends carry plus thread and left-hand thread.
The upper adjustment bar carries left-hand thread.
The lower adjustment bar carries plus thread.
A kind of adjusting bellows installing/dismounting method：
1st, the spacing of lower flange on bellows pipeline to be installed is measured, while this spacing adds the thickness of upper and lower two gaskets
Degree.
2nd, the effective adjusting bellows protection installing and dismounting bar of ripple to be installed is formed into 120 degree of encirclements, locking is adjustable
Whole nut.
3rd, bellows compression is carried out according to the spacing measured, is measured simultaneously in compression process and keep the flat of lower flange
Row degree, decrement are more than the spacing measured and the gasket amount of flange.
4th, compressed bellows is put into position to be installed, makes the flange eye of bellows and the flange eye of upper lower flange right
Installation bolt after just.Adjustable nut is slowly unclamped, lays down ripple protection of pipe installing and dismounting bar group.
