Description

A kind of adjustable oversleeve through walls of pipeline
Technical field
The utility model belongs to field of engineering technology, more particularly, to a kind of adjustable oversleeve through walls of pipeline.
Background technology
In existing technology, pipeline with oversleeve through walls mainly for solving from pipeline to the seepy question of pipeline well room, Sealing function is played, mainly by steel bushing, catch, bolt, the structure compositions such as rubber ring, the structure of oversleeve through walls is simple, mainly by Catch and the rubber ring of steel bushing crush seal intracavitary achieve the effect that sealing.This mode is although simple in structure, but seals Poor reliability, during the installation process, due to installation error, catch and steel bushing can not possibly be absolutely coaxial, such rubber ring by It is possible to distort when extruding or excessive deformation, causes sealing effect poor;In addition, during conduit running, due to pipeline The equal stretching motions that expand with heat and contract with cold, influence the compaction degree of sealing ring, lead to seal failure;Simultaneously because excessive extrusion is also easy to make Rubber ring and seal chamber sleeve adhesion are obtained, certain difficulty is all brought to maintenance and the replacement of sealing material.
Invention content
In view of this, the utility model is directed to a kind of adjustable oversleeve through walls of higher pipeline of sealed reliable degree, Poor to solve existing oversleeve sealing effect, sealed reliable degree is relatively low, and sealing material service life is short, needs to frequently replace sealing The problem of material, pipeline oversleeve and sealing ring easy adhesion.
In order to achieve the above objectives, the technical solution of the utility model is realized in:
A kind of adjustable oversleeve through walls of pipeline, including gland, seal cavity, bolt assembly and rubber coil assembly, wherein Gland is connected with seal cavity by bolt assembly, and rubber coil assembly is placed in the seal chamber formed between gland and seal cavity In, rubber coil assembly includes rubber ring and rubber ring sleeve, and rubber ring is placed in inside rubber ring sleeve, and gland includes gland ring and gland One end of sleeve, gland sleeve is fixedly connected on the inside of gland ring, and seal cavity includes connection ring, seal chamber sleeve, sealing One end of chamber ring and conduit sleeve, seal chamber sleeve is fixedly connected on the inside of connection ring, and the other end of seal chamber sleeve is fixed It is connected between seal chamber ring inner side and outer side close to the position of inside, one end of conduit sleeve is fixedly connected on seal chamber ring Inside, gland sleeve is identical with the internal diameter of conduit sleeve, and the internal diameter of seal chamber sleeve is more than the internal diameter and pipeline set of gland sleeve The internal diameter of cylinder, the outer diameter of seal chamber ring are more than the outer diameter of seal chamber sleeve.
Further, the adjustable oversleeve through walls of the pipeline, rubber ring sleeve include a metal baffle ring and metal sleeve, Metal sleeve is fixedly connected on the outside of metal baffle ring.
Further, the pipeline is pacified with adjustable oversleeve through walls in the seal chamber formed between gland and seal cavity Equipped with ring spring, ring spring is squeezed between gland sleeve and rubber ring sleeve.
Further, the adjustable oversleeve through walls of the pipeline, bolt assembly include stud and nut, stud It is connected on gland ring and connection ring, nut is threadedly attached in the adjacent one end of stud, and nut abuts against gland The outer surface of ring.
Compared with the existing technology, this pipeline is had the advantage that with adjustable oversleeve through walls:
(1) the adjustable oversleeve through walls of pipeline described in the utility model, seal cavity is interior to place the indefinite rubber of quantity Coil assembly, such user can place the quantity of rubber coil assembly according to pipeline specifications difference unrestricted choice so that the design scheme The scope of application it is more extensive;In prior art, the structure of oversleeve through walls is simple, mainly by catch and steel bushing crush seal intracavitary Rubber ring achieve the effect that sealing, in the installation process of oversleeve, due to installation error, catch can not possibly be absolutely with steel bushing Coaxially, such rubber ring is possible to distort when being squeezed or excessive deformation, causes sealing effect poor, present design In, due to containing rubber ring sleeve in rubber coil assembly, and rubber ring is placed in the inside of rubber ring sleeve, and rubber ring sleeve plays one It is metal material to separate and protect the effect of each rubber ring, rubber ring sleeve, there is load effect, prevents rubber during extruding Circle distortion and excessive deformation, can reinforce sealing effect;In the prior art, sealing material after a period of use, due to rubber ring Aging is deformed, be easy and seals steel bushing adhesion, certain difficulty is all brought to maintenance and the replacement of sealing material, in the design side In case, since the rubber ring as sealing material is placed in inside rubber ring sleeve, rubber ring sleeve can separate rubber ring and seal cavity Inner wall prevents rubber ring from sticking on seal cavity inner wall, and cleaning is replaced and maintenance is all more convenient.
(2) pipeline described in the utility model adjustable oversleeve through walls is equipped with ring spring inside seal cavity, can rise To the effect for increasing pretightning force.During conduit running, due to the equal stretching motions that expand with heat and contract with cold of pipeline, sealing ring is influenced Compaction degree leads to seal failure, in this case, due to being added to ring spring in seal intracavitary, when conduit running causes bolt loose Dynamic, when influencing the compaction degree of sealing material, spring can be compensated automatically to sealing material in a certain range as elastomeric element Pressing force enhances the sealed reliable degree of pipeline oversleeve, extends the service life of sealing material, reduces the frequency replaced and overhauled.
(3) the adjustable oversleeve through walls of pipeline described in the utility model, can be by adjusting the elastic adjustment gland of nut Pressing force and spring elastic force, realize the adjustable purpose of oversleeve through walls.
