Description
Technical field
It the utility model is related to pressure sealing equipment technical field, and in particular to a kind of ca(u)lk formula flange blocking clamper.
Background technology
In serialization process industry production field, the leakage problem of fluid media (medium) is still to cause various serious accidents to occur
Principal element.The technical way both at home and abroad for accident of stopping a leak is to use Live leaking-stopping technology at present, to reach
Quickly stop a leak, ensure the purpose of safety in production normal operation.
Live leaking-stopping technology is after specializing in former sealing structure failure, how not reduce pressure, temperature and leakage stream
Under conditions of amount, an emerging engineering technology for the purpose of on-line pressure sealant structure is re-created on leakage defect position rapidly
Subject.On-line pressure sealant technology uses on-line pressure sealant fixture, on-line pressure sealant injecting and hydraulic injection instrument, can be in pressure：Vacuum~
32MPa；Temperature：In the range of -198 DEG C~800 DEG C, all kinds of dielectric leakages that serialization process industry production field occurs are eliminated,
With without stop production, safe and reliable and service life is long the characteristics of.Its general principle is：" injected to specific closed cavity special
With injecting sealant, reach the operating unit sealing load stopped needed for leakage, realize sealing purpose again ".It is to be related to mechanics, hydraulic pressure skill
A multi-disciplinary comprehensive application technology such as art, high polymer material, inorganic material, Metal Material Science, rheology, is flow
Industry security produces and the indispensable emergency repair technology of public safety, belongs to Sealing Technology category, wherein Chinese people's republicanism
State's subject classification and code is：4107010.
" closed cavity " in Live leaking-stopping technology is mainly to be made up of " blocking clamper " and leakage position outer surface, is had
Strict intensity, rigidity and seal clearance requirement.Therefore, blocking clamper is that leakage defect position is arranged in Live leaking-stopping technology
Outside, sealing cavity is formed with leakage defect site portion outer surface, there is provided the hardware that strength and stiffness ensure, be to determine
The key link of Live leaking-stopping technology application success or failure.
The effect of blocking clamper：
One of effect of blocking clamper, it is to contain to be expelled to outside on-line pressure sealant fixture and leakage position part by injection gun
The injecting sealant in sealing cavity that surface is formed, ensure injecting sealant filling, maintain injecting pressure be incremented by, prevent it is close
The injecting sealant that envelope injecting is excessive, makes to be expelled in fixture produces enough seal pressures, stops leakage.Referred to as sealing ensures.
The two of the effect of blocking clamper, powerful injection pressure caused by injection gun and leaking medium pressure are subject to,
Do not allow appearance to deform and displacement, be the rigidity guarantee system of newly-established sealing structure.Abbreviation rigidity ensures.
Other blocking clamper also has a booster action, i.e., connects injection gun by injecting hole and provide injecting passage.
The design criteria of the effect of blocking clamper：
Because blocking clamper has the function that to hold the balance in " Live leaking-stopping technology ", the quality that it is designed will be closed directly
It is success or failure to pressure sealing operation and field operation time, many index such as consumption of injecting sealant.It should follow following
Criterion：
1) well coincide property.The blocking clamper shape designed and produced allows for complete with the outer shape of leakage position
It coincide.
2) enough intensity.Blocking clamper is bearing the supercoated stresses such as injecting pressure, leaking medium pressure and mount stress
Under effect, it is not allow for any breakoff phenomenon and occurs.
3) enough rigidity.Blocking clamper is bearing the supercoated stresses such as injecting pressure, leaking medium pressure and mount stress
Under effect, any type of displacement and deformation are not allow for, ensures the formation and maintenance of seal pressure.
4) suitable sealing cavity.There must be the sealing cavity of a closing between blocking clamper and leakage position, so as to
In injection and contain injecting sealant.The width of sealing cavity should exceed 20~40mm of actual size of leakage defect or so, close
The height of cavity is sealed, that is, forms the thickness of the injecting sealant of sealing structure of rock, typically should be between 6~15mm, special circumstances are also
It can thicken.
5) contact gap is tight.Gap and leaking medium pressure of the blocking clamper with the contact portion of leakage position outer surface
In inverse ratio.When this gap can not effectively prevent injecting sealant excessive, then it is contemplated that in fixture and leakage defect contact site
The sealing structure of ring, flute profile sealing structure or other forms is designed and produced on position, increases the excessive resistance of injecting sealant.
6) injecting hole opens up.In order to which high pressure injection gun is connected on blocking clamper, and by high pressure injection gun sealing
Injecting is expelled in sealing cavity, and tapped injecting hole should be provided with blocking clamper.The quantity in injecting hole and distribution are with energy
Injecting sealant is filled whole sealing cavity is advisable.On-line pressure sealant fixture must be discharged during in view of plugging operations with letting out
The gas in sealing cavity that leakage site portion outer surface is formed, while discharge not yet stops the pressure medium of leakage, typically
More than two injecting holes should be at least provided with fixture.
7) piecemeal is reasonable.Blocking clamper should be partitioned organization, on leakage position after be linked to be rigid entirety again,
Form the sealing cavity of a closing.According to the size of on-line pressure sealant fixture, and the concrete condition of leakage position is combined, band densification
Binder has the number that can be designed to two equal portions, three equal parts or more.
But existing common leak stopping is clipped in when tackling disposal high temperature, the equipment of high pressure or pipe flange leakage, or it is actual
When leakage flange has step, mismatch, because being influenceed by flange temperature and temperature deformation, cause effectively make flange clamp
Reach requirement with the outer peripheral sealing of leakage flange.
Utility model content
The purpose of this utility model is to be directed to technological deficiency present in prior art, and provides one kind not by leakage flange
Temperature is placed restrictions on, and is let out in the absence of temperature deformation influence for disposal high temperature, high pressure flange in " Live leaking-stopping technology " or actually
Step, mismatch and the ca(u)lk formula flange blocking clamper of leakage accident occurred be present in leakage flange.
Technical scheme is used by realize the purpose of this utility model：
