Description
Technical field
The present invention relates to a kind of pipeline jig, more particularly to agent injecting type pipeline jig is isolated in a kind of fastening type.
Background technology
Currently, the various positions such as equipment, pipeline, valve in process units, when being leaked caused by certain reason, leakage is situated between
Matter band temperature, jet flow state with pressure and outside.Leakage position：Flange, equipment, the hole on pipeline, weld defect, screw thread connect
Head gland leakage etc..Leaking medium：Water, water vapour, air, oxygen, nitrogen, coal gas, ammonia, liquefied gas, gasoline, diesel oil, coal
Oil, heavy oil, lubricating oil, acid, alkali, esters, alcohols, benzene class, various heat carriers, various hydrocarbons, various chemical gas, liquid
The leakage part of the All Medias such as body can be gone to eliminate with this technology.Technology implementation process can utilize original closed of leakage position
Cavity, or a closed cavity is established on leakage position, it is more than the external thrust of medium system pressure, there will be modeling
Property, curability, the sealant for being resistant to leaking medium and temperature injects and is full of enclosure space, blocks leakage defect and channel, close
Seal agent under certain conditions, it is rapid to cure, one new sealing structure is set up on leakage position, eliminates medium
Leakage.Not parking on-line pressure sealant technology is the sophisticated equipment maintenance technique that middle nineteen seventies grow up, when process units and
When the leakage of the equipment of enterprise, pipeline various positions, can not it be influenced in the case that production carries out not parking, band is warm, with pressure,
Rapidly, it reliably and securely stops a leak.
The leakage of process units fluid media (medium) is repaired by not parking on-line pressure sealant technology, mostly uses agent injecting type Sealing Method, it is real
Apply closure operation.This encapsulating method adaptive temperature is from -180 DEG C~800 DEG C, and pressure is from each under the conditions of -0.1MPa~35MPa
The kind leakage sealed construction of fluid media (medium).But construction procedure is complicated, including fixture mounting and adjusting orientation, injecting operation it is noted that
The coordination of fltting speed and sealant cures time carries out effect observation after completing injecting and after-teeming compresses.One of link
Control it is improper will influence block quality, this not only jeopardizes operating personnel and special equipment safe operation, is also unfavorable for resource section
About and environmental protection.
Currently, when defect of pipeline size is larger or a certain range is thinned, mostly use by blocking isolation, then installs fixture
Contain leakage position, implements injecting sealing.Although leakage equipment wall thinning area can be made to lose to avoid because of injecting extruding
Surely, it and also effectively prevent injecting sealant being injected into medium system.But injecting seal construction method is isolated in this block, behaviour
Make more complex, sealant consumption is more.
Invention content
