Description
Technical field
The utility model relates to underground piping technical field, specially a kind of steel made two-side casing expander.
Background technique
Pipe-line system can generate line expansion or linear shrinkage because expanding with heat and contract with cold, so that the safe operation of pipe-line system is influenced,
In this regard, usually using being compensated as the pipeline compensator of core element to expanding with heat and contract with cold for pipeline using bellows.However, existing
There is pipeline compensator to have the disadvantage that firstly, the bellows material used is usually 300 series stainless steels, in order to meet axis
The bit shift compensation performance big to stroke usually selects thin-wall stainless steel to be process through hydraulic, especially intolerant to underground water and soil
The corrosion of corrosive medium in earth environment usually requires a large amount of FlexbleJoint of setting in pipe-line system, due to bellows at
The presence of type stress, cause FlexbleJoint installation and using when if there is there is tensile stress (stretching displacement) to be placed in corrosion ring
FlexbleJoint is easy for stress corrosion in border, it is assumed that and out-of-alignment words in both ends are easy to cause fatigue damage again when installation, so
Improve the construction cost of pipeline；Secondly, existing pipeline compensator is to avoid medium to the straight of ripple inside pipe wall in use process
It connects to wash away needs and design and has guide shell, have the flowing of guide shell medium with regard to directional, this is for needing medium to have circumferential stream
The flow direction of dynamic desired pipeline such as medium will be limited, and the normal operation of pipeline cannot be effectively ensured, in other words if
Regulation enforcement is not pressed, pipeline operation there is security risk.For this purpose, it is proposed that a kind of steel made two-side casing expander.
Utility model content
The purpose of this utility model is to provide a kind of steel made two-side casing expanders, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of steel made two-side casing expander, including
The bolts and nuts being fixedly connected are acted at ontology, two groups of pressure rings, two groups of sealing rings and both ends, are all provided at left and right sides of the ontology
Be equipped with sealing ring, pressure ring be provided on the outside of the sealing ring, the pressure ring compresses sealing ring, the pressure ring by bolt with
Nut is fastenedly connected with ontology.
Preferably, the ontology includes two groups of stuffing-boxes for installing sealing ring, is welded between stuffing-box described in two groups
Between take over.
Preferably, the pressure ring is formed by taking over flange welding, is squeezed on the right side of the adapter tube and is provided with sealing ring.
Preferably, the stuffing-box is provided with sealing ring mounting groove, and the sealing ring is mounted in sealing ring mounting groove, institute
Stating sealing ring material is a kind of compound nitrile rubber as prepared by butadiene and acrylonitrile compolymer, construction profile be can with fill out
The tenon shape elastomer that material letter fits closely.
Preferably, the flange annular array offers connecting hole, and the stuffing-box offers corresponding with connecting hole logical
Hole.
Preferably, the flange and stuffing-box are by bolt-through connecting hole and through-hole, and are fixed by nut and gasket.
Compared with prior art, the utility model has the beneficial effects that
1. the sealing ring used is multiple using a kind of steel made two-side casing expander prepared by butadiene and acrylonitrile compolymer
Nitrile rubber is closed to form through pressure injection, so that making it not only has the attriting performance for meeting sealing and the frequent axial stretching of resistance to pipeline,
Even more there is axial stretching displacement that compensation pipeline is big and the big axially mounted deviation of compensation pipeline and excellent convenient for what is fast installed
Point, it is clear that it is resistance to underground water and soil that the raising of compensation performance, which will lead to the compensator quantity needed in pipe-line system and reduce more crucial,
The corrosion of corrosion factor in earth, and mended needed for capable of meeting under conditions of using lesser amt steel made two-side casing expander
Because of relative displacement caused by the temperature difference or Geological Reasons in the pipe-line system repaid, and due to sealing ring axial length is longer can be more
Effectively absorb vibration caused by under pipe-line system starting, stopping or normal running (operation) conditions and ambient environment vibrations source；
2. creating point uses two opposing stationary sealing rings, so as to realize medium in two-way flow wherein,
The service efficiency of compensated pipe-line system is improved, and then has saved cost, especially maintenance cost and installation cost；
3. designing middle adapter on the body, it is thus possible to meet and guarantee the axial excessively flexible of pipeline, ensure that it
The presence of big axially mounted deviation when stretching in maximum compensation rate limits and allowing to construct and repair, thus significantly
The skill requirement to site operation personnel is reduced, and has prevented the security risk of site operation and operation, and be easier to as pipeline
Safe operation provides technical guarantee.
