Description
Technical field
This utility model is related to technical field of pipeline connection, and more particularly to one kind is flexible coupling pipeline.
Background technology
In existing residenter house, pipeline is often adopted and is rigidly connected.During house decoration, often to body of wall
Carry out pounding the operations such as wall, the vibrations of generation can slightly shake loose the bolt that pipeline connects, when coming earthquake, pipeline be likely to by
Bolt shakes loose completely；At this moment the sealing structure of pipeline is destroyed, and tap water or natural gas of inside etc. are leaked, and cause secondary
Disaster.
The existing pipeline that is flexible coupling refers to the Chinese patent of Application No., it discloses a kind of pipeline flexible connection structure,
For connecting the first pipeline and the second pipeline, comprising retainer ring, flexible connecting member, steel ring and pipeline adaptor are supported, wherein, institute
State the middle part for supporting steel ring to be arranged on the flexible connecting member；The pipeline adaptor is connected with the first pipeline；The flexibility is even
The two ends of fitting are connected respectively by retainer ring with second pipeline and pipeline adaptor.
But the utility model is not open to ensure bubble-tight structure between the first pipeline and the second pipeline, if first
Pipeline is not all right with the air-tightness of the second pipeline, when coming earthquake, it is likely that leakage phenomenon occurs, and secondary disaster occurs.
Utility model content
The purpose of this utility model is to provide a kind of first pipeline and the second pipeline seals the pipeline that is closely flexible coupling.
Above-mentioned technical purpose of the present utility model technical scheme is that：
One kind is flexible coupling pipeline, including the elastomer connector of first, second pipeline of first, second pipeline and connection, rubber
Joint includes hollow rubber part and two loose flanges, and loose flange is respectively sleeved at hollow rubber part two ends, hollow rubber part
Two ends are molded with bare terminal end, and two adjacent opposite sides of loose flange are abutted with bare terminal end, and first, second pipeline adjacent surface is cast
Connecting plate, connecting plate and loose flange bolt connection and bolt-through bare terminal end are made.
By adopting such scheme, as bolt is screwed, connecting plate is gradually tensed with loose flange, so as to by bare terminal end
Clamp；Because bare terminal end is made up of rubber, with good elasticity, therefore clamp with loose flange when bare terminal end is connected plate,
Bare terminal end compressive deformation, makes up the gap between connecting plate and loose flange, so as to prevent the fluid leakage of inside；When vibrations are sent out
When raw, due to connecting by elastomer connector, as a kind of flexible connection, vibrations are not only absorbed, prevent bolt to be quaked loose, also compensated for
The respective sedimentation of first, second pipeline, it is ensured that first, second pipeline is completely embedded.
Preferably, bare terminal end is connected with sealing ring away from loose flange side, connecting plate is provided with for the recessed of sealing ring grafting
Groove.
By adopting such scheme, sealing ring is inserted in groove, sealing ring fills up groove, and not only bare terminal end is carried out
It is spacing, and another seal structures are formed, enter an air-tightness ensured between first, second pipeline.
Preferably, under sealing ring naturalness, the depth of groove is less than the height of sealing ring.
By adopting such scheme, because sealing ring is highly less than the depth of groove, when by the fully-inserted groove of sealing ring
Afterwards, sealing ring compressive deformation, the gap between sealing ring and groove floor is fully sealed, it is ensured that between first, second pipeline
Sealing.
Preferably, under sealing ring naturalness, groove leaves the gap made up for sealing ring deformation in sealing ring both sides.
By adopting such scheme, after groove that sealing ring is fully-inserted, sealing ring compressive deformation, by flat close of buckling
Seal ring not only fully seals in the gap with groove floor, also fully seals in the gap with recess sidewall, it is ensured that first, second
Air-tightness between pipeline, prevents from causing sealing ring to be extruded because groove is too small, so as to prevent the sealing ring being extruded from will press from both sides
End jack-up is held, and then ensures that bare terminal end is fitted closely with connecting plate and loose flange.
Preferably, having stopping means between two connecting plates, stopping means include screw rod and are fixed in connecting plate outside
Two limited blocks, screw rod two ends extend through two limited blocks and are threaded with nut, and nut is located at two limited blocks outside
And leave gap with limited block.
By adopting such scheme, stopping means are to protect elastomer connector to avoid the device for being subject to pull danger, by rubber
The displacement of joint is controlled in certain scope so that it is guaranteed that elastomer connector and the stable operation of pipeline, more acute so as to work as earthquake
When strong, when a pipeline comes off from installing rack, stopping means and another pipe-support this root pipeline, during one section of strong support
Between, be resident family strive for preciousness flee from the time.
Preferably, the nut quantity of screw rod one end is two and mutually abuts.
Double nut pair is formed by adopting such scheme, two nuts, it is ensured that nut is fixed on screw rod two ends, prevents because of shake
Move and shake loose on nut.
Preferably, stopping means quantity is three and is circumferentially uniformly arranged.
By adopting such scheme, first, second pipeline is fixed jointly by three stopping means, bulk strength is higher,
It is more uniformly stressed, when earthquake is more violent, the pipeline for coming off is supported jointly by three stopping means, when striving for more
Between.
Preferably, hollow rubber part includes textile reinforcement and the rubber layer positioned at textile reinforcement both sides.
Stretched repeatedly during vibrations are absorbed by adopting such scheme, hollow rubber part, textile reinforcement strengthens
The intensity of rubber, extends the life-span of hollow rubber part, and when relatively violent, pipeline departs from for earthquake, hollow rubber part can be certain
Ensure the connection of first, second pipeline in time.
Preferably, being clamped with the sheet metal being coaxially disposed in bare terminal end.
Strengthen the intensity of bare terminal end, prevent bare terminal end by loose flange and connection sheet by adopting such scheme, sheet metal
Folder is damaged.
Preferably, sheet metal is provided with the through hole for bolt-through.
Sheet metal is fixed by adopting such scheme, bolt-through sheet metal, further limits the position of bare terminal end,
Ensure that bare terminal end is completely embedded with connecting plate and loose flange.
In sum, this utility model has the advantages that：Elastomer connector not only absorbs vibrations, prevents bolt from being shaken
Pine, also compensates for the respective sedimentation of first, second pipeline, it is ensured that first, second pipeline is completely embedded；And bare terminal end is held in company
Between fishplate bar and loose flange, sealing ring is fully inserted in groove, forms double-deck cumulative sealing structure, it is ensured that first, the
Two pipelines and the sealing of elastomer connector；Stopping means are to protect elastomer connector to avoid the device for being subject to pull danger, by rubber
The displacement of joint is controlled in certain scope so that it is guaranteed that elastomer connector and the stable operation of pipeline.
