Abstract

The invention discloses an under-pressure flange bolt punching, glue injecting and leakage stopping method. The method comprises the following steps that high-pressure flange leakage point stopping is finished through the procedures such as holed bolt machining, opposite-clamping annular leakage stopping clamp machining, holed bolt replacing and bolt hole glue injecting. According to the under-pressure flange bolt punching, glue injecting and leakage stopping method, under the situation that production is not affected, glue injecting and leakage stopping are conducted on a punched hole of a flange bolt, a high-pressure injection agent gun is utilized for forcibly injecting a sealing injection agent into a sealed cavity formed by the clamp and part of the outer surface of a leakage part under the action of manual external force, and the leakage defect is rapidly overcome; and under the condition that the injection agent pressure is far larger than the leakage medium pressure, leakage is forcibly stopped, the sealing injection agent can be kept in a certain working sealing specific pressure, a plastomer is converted into an elastomer within short time, a novel hard sealing structure rich in elasticity is formed, and the purpose of sealing is achieved.

Description

A kind of flange bolt perforating injecting glue blocking method with pressure
Technical field:
The present invention relates to gas leakage stopping technology field, particularly relate to a kind of flange bolt perforating injecting glue blocking method with pressure.
Background technology:
In coal chemical industry produces, in pipeline, flowing is inflammable, explosive medium, some gas medium or poisonous Jie Matter, owing to system start-stop car flange temperature produces change, causes flange seal mat to loosen the leakage easily producing gas, this kind of Leak flow velocity with the gas of pressure fast, easily easily produce with windage catch fire, explosion danger accident and pollution environment etc. Unsafe factor, affects the stability of the normal technological process of production and the quality of product, i.e. the waste energy pollutes again surrounding, As processed not in time, cause tremendous economic loss to enterprise and bring baneful influence to society, accordingly, it would be desirable to reasonable in design Blocking method.
Summary of the invention:
In order to make up prior art problem, it is an object of the invention to provide a kind of flange bolt perforating injecting glue blocking method with pressure, It is applicable to Coal Chemical Industry is produced gas, the head conduits of other industry production fuel gas industry conveying such as flammable, poisonous And store the band pressure flange of press device with the gas such as flammable, poisonous, it is possible to conscientiously ensure the pressure of conveying gas material Pipe safety stable operation, can be substantially reduced maintenance and the maintenance cost of pipeline and equipment.
Technical scheme is as follows:
Flange bolt perforating injecting glue blocking method with pressure, it is characterised in that comprise the steps:
1), processing eye bolt: select and flange matches the bearing flange bolt of model of the same race, at bearing flange bolt-center Carrying out perforating tapping so that injecting glue, pore size can coincide with the hollow Studgun head of suppressing of plugging gun after tapping, then Bearing flange bolt is made a call to a cross-drilled hole be mutually communicated with vertical core, form " fourth " font hole;
2), processing is to clamp ring type plugging chucking tools, i.e. grooved ring flat-plate: process an internal diameter and bearing flange bolt external diameter quite in have ring The steel loop of groove, interior groove width is slightly larger than two flange spacing, and both sides make to be connected with and fasten;If flange can add in pipeline one end The integral circular ring type of work;
3), eye bolt is changed: first change the bearing flange bolt in band " fourth " the word hole of processing in flange leakage point lateral symmetry, by Individual replacing also uses a kilogram spanner to be fastened to the corresponding moment of flange, can not change two or more than two bearing flange spiral shells simultaneously Bolt, bearing flange bolt cross-drilled hole should be between two flange gaps, and bearing flange bolt vertical core should be robbed adapter and be connected with leak stopping;
4), clamp ring type plugging chucking tools is installed: being processed into two semicircular wafer type plugging chucking tools, utilize bolt to be fastened on two flanges On annular end face, inside flange break joint fixture to be stuck in groove;
5), bolt hole injecting glue: screw suppress necessarily in the middle of leak source far-end two is lateral both sides bolt hole carry out successively suppressing injecting glue, Until leak source can only be emerged leaked gas body from last bolt pressurizing port, the hollow Studgun head of suppressing of plugging gun is screwed in Later high-pressure bolt is suppressed on hole, should rapidly bolt be twisted after equally suppressing clamp ring type plugging chucking tools injecting glue meanwhile On hole, high pressure flange leak source is blocked.
Described flange bolt perforating injecting glue blocking method with pressure, it is characterised in that comprise the steps:
1), processing eye bolt: select and flange matches the bearing flange bolt of model of the same race, at bearing flange bolt-center Carrying out perforating tapping so that injecting glue, measured the perforating degree of depth and aperture in advance, the degree of depth is generally the 1/2 of bolt length, and aperture is big Little can suppress Studgun head with plugging gun hollow after tapping and coincide, then beat at the 1/2 of bearing flange bolt length One cross-drilled hole is mutually communicated with vertical core, forms one " fourth " font hole;
2), processing is to clamp ring type plugging chucking tools, i.e. grooved ring flat-plate: process an internal diameter and high pressure flange external diameter quite in have annular groove Steel loop, interior groove width is slightly larger than two flange spacing, it is simple to suppressing glue filling method your beautiful writings gap, both sides make to be connected with and fasten;As Really flange can be processed into overall circular ring type in pipeline one end;
3), eye bolt is changed: first change the bearing flange bolt in band " fourth " the word hole of processing in flange leakage point lateral symmetry, by Individual replacing also uses a kilogram spanner to be fastened to the corresponding moment of flange, and a general leak source needs to change 4 ~ 6, and can not be simultaneously Changing two or more than two bearing flange bolts, in case leak source increases uncontrollable, bearing flange bolt cross-drilled hole should be in two methods Between your beautiful writings gap, bearing flange bolt vertical core should be robbed adapter and be connected with leak stopping;
4), to clamp ring type plugging chucking tools install: flange the most in the duct between cannot directly apply mechanically, being processed into two semicircular pair Clip plugging chucking tools, utilizes bolt to be fastened on two flange annular end faces, inside flange break joint fixture to be stuck in groove, prevents from suppressing Flowed out by flange slot during injecting glue;
5), bolt hole injecting glue: screw suppress necessarily in the middle of leak source far-end two is lateral both sides bolt hole carry out successively suppressing injecting glue, Until leak source can only be emerged leaked gas body from last bolt pressurizing port, the hollow Studgun head of suppressing of plugging gun is screwed in Later high-pressure bolt is suppressed on hole, rapidly bolt should be screwed on hole, prevent after equally suppressing with grooved ring flat-plate injecting glue Pressure ejects suppressing glue, has operated rear high pressure flange leak source and has blocked.
The invention have the advantage that
The present invention is not in the case of affecting production, and by flange bolt perforating is carried out injecting glue leak stopping, it is according to sealing note Agent, under the effect of artificial external force, utilizes high pressure injection gun injecting sealant to be expelled to by force fixture and leakage position part appearance In the sealing cavity that face is formed, promptly make up leakage defect, under conditions of injecting pressure is much larger than leaking medium pressure, Leakage is stopped by force, and injecting sealant self is able to maintain that certain operating unit sealing load, and at short notice by plastic body It is changed into elastomer, forms hard, a whippy new sealing structure, reach the purpose sealed.
