Description
Technical field
The present invention relates to pipe pressurized technical field of sealing technology, more particularly to the isolated sealing clamp of a kind of pressure pipeline and close
Envelope technique.
Background technology
The isolated on-line pressure sealant fixture of pipeline of the prior art, be without sealing reinforcing element, i.e.,：Sealing clamp
It is only that injection/filling sealing agent is sealed in isolation channel, this operating method has the disadvantages that：
1st, apply when being not easy to be found the pipeline of its deformation, applicability can be poor.
If pipeline hair deformation（Tube section is non-round）, and the mounting hole of conventional sealing clamp is typically all rule
Circular hole, then the assembly precision of itself and pipeline will be poor, and after showing as sealing clamp installation, it can exist larger with pipeline enclosure
Assembling gap, assembling gap it is larger, sealant is leaked, injecting glue extruding force is unable to reach design pressure, finally can equally make
Whole on-line pressure sealant procedure failure.
, it is higher to the precise requirements of in-site measurement size, and fixture fit-up gap can not caused by measurement error
Adjustment compensation.
According to《Bearing device on-line pressure sealant technical specification》Proved in regulation and practical application in GBT 26467-2011,
The fit-up gap of sealing clamp most very much not allows more than 0.5mm, therefore, to ensure the assembly precision of sealing clamp, then will
In-site measurement is asked to need to ensure higher accuracy.And at the scene under the influence of severe work condition environment, it is many times to be difficult
Ensure the accuracy of measurement.Such as：In the environment of leaking HTHP, poisonous and harmful medium, survey crew is closely close
Leakage point stops for a long time, has any problem very much, then just determining the technical ability of in-site measurement personnel will have higher requirements
It can ensure that the precision of measurement.
If in addition, pipeline is present when being not easy the deformation being found, or itself being exactly not specification shape, that depends on merely people
Measurement technical ability（Not by other special instruments or complementary tool）, often it is difficult to ensure that measurement accuracy.
Therefore, it is difficult to ensure that in measuring accuracy, sealing clamp can not compensate to fit-up gap again in the case that, lets out
The efficiency and construction quality of leak source on-line pressure sealant can substantially reduce.
, sealing clamp processing technology require high, and fit-up gap can not adjust/compensate when mismachining tolerance occurs in fixture,
It can only do over again.
Such as：Sealing clamp to welding machine-shaping, if deviation occurs for control technique in processing and making process, by
In welding temperature distortion, the gap of the combinatorial surface of sealing clamp can be larger.Gap is larger, sealant is leaked, injecting glue extruding force
Design pressure is unable to reach, finally can equally make whole on-line pressure sealant procedure failure.
Therefore if the combinational gap of sealing clamp is larger, or other fitted positions processing miss it is larger when, clips
Tool can only do over again or re-work.
