Description
Technical field
The present invention relates to a kind of pipe leakage point sealing device.
Background technology
The destruction of pipeline is generally segmented into three classes：The first kind is local small destruction, such as aperture or crackle leakage.This
Class leakage is typically what is caused by local corrosion or weld defect.Equations of The Second Kind is local failure, it is necessary to add protection outside steel pipe
Set replaces destroyed part with short tube.This kind of destruction is most common, and for example ship grasp is hung.3rd class is in considerably long pipeline section
The upper a wide range of destruction of appearance, causes pipeline axial strength to substantially reduce.Such case needs to replace destroyed portion with long pipeline section
Point.
Pipeline is most commonly seen failure mode due to the local leakage that local corrosion or weld defect are caused.It is logical at present
Repaired frequently with the local mode replaced.Local replace needs long-time stopping transportation to carry out local replacing, and cost is higher, and
Need to use welding, it is therefore desirable to which pipeline section is cleaned, displacement nitrogen, prevents blast.By the way of external reinforcing remedy be
Quickly repairing method the most economic.Some the repairing pipe measures of following patent disclosure.
Patent CN201320801593.2, fluid pressure type oil-gas pipeline breakage prosthetic device, using the first mending-leakage semicanal and the
Two mending-leakage semicanals synthesize a cylinder, will leak out and a little cover, and carry out axial seal by the way of welding.
A kind of patent CN201320890630.1, pipe leakage point sealing structure is merged using upper box and lower box and detained
In leakage part, upper lower box, which is constituted, installs drain valve and connecting pipe on a quad seal case, casing.
Patent CN201320890887.7, a kind of annular chuck for repairing pipe, using the clip of two semicircular rings,
Hold the connection of pipeline blending bolt tightly.Elastomeric material is set between clip and pipeline.
A kind of patent CN201420081473.4, pipe pressurized leakage compensating device is docked using the first slips and the second slips
Composition circle is logical and is enclosed on outside pipeline, and liner is set between slips and pipeline.
Patent CN201420096705.3, Hafu-type pipeline connection repair apparatus, the patent is directed to running water pipe, using two
The mode that individual semicircle holds encryption seal tightly is implemented to leak dot encapsulation.
Patent CN201420335934.6, a kind of pipeline pressure-bearing leakage compensating device, mainly to city tap-water, heating, blowdown
Mending-leakage is carried out Deng pipeline with pressure.Arc pressuring plate is pressed on pipeline outer wall by U bolt, and passes through seal with elastometic washer.
Patent CN201420641802.6, one kind is used for the online leakage compensating device with pressure of non-combustible gas pipeline, by upper
Lower mending-leakage semi-circular tube is connected with holding pipeline tightly.Drive by-passing valve on the corresponding mending-leakage semi-circular tube of leak, mending-leakage when
Time can open by-passing valve aerial drainage.
Above leakage repairing device for pipe line substantially all holds pipeline tightly using two semi-cylindrical shells, and in pipeline and cohesion device
Between gasket seal is set.Such mode axial seal is difficult to ensure that, and the difficult sealing between two semi-cylindrical shells
To realize.Therefore, method is blocked described in above patent, it is difficult to tackle pressure piping, especially pipe-line local leakage
It is difficult to realize closure using above method.
In addition, existing pipeline external strengthens repairing method, generally using being connected with after housing holding tube or with weldering
The mode fixed shell connect, and sealed by the way of housing adds encapsulant.Upper-lower casing, which merges, once to be completed
The axial seal between radial seal and housing and pipeline between housing.So regulation pretightning force is more difficult, often difficult
To ensure that two kinds of sealing means are effective simultaneously.
In summary, for the high-risk pipeline of high pressure, to the external reinforcing repairing method technology and equipment of local leakage point still
Immature, the innovation and research and development of correlation technique have larger application value.
