Description
Technical field
A kind of Novel clamping apparatus for revealing flange closure of this utility model.
Background technology
In the fields such as oil, oil refining, combustion gas, chemical industry, power plant, naval vessel, when relating to the situation of various pipes and container tank corrosion failure evaporating, emitting, dripping or leaking of liquid or gas, typically require and take certain technological means that above-mentioned leak site is blocked, effectively to control high temperature, high pressure, the leakage of the medium such as poisonous.The technological means of above-mentioned leak site closure typically requires applicable following medium: deep-etching class medium, all kinds of chemicals etc. such as the gases such as oil, water, combustion gas and steam, sulfur, acid, alkali, ammonia, benzene.Especially in oil refining field, the quality of above-mentioned blocking technology means directly affects whether safety in production can be normally carried out, and is directly connected in production process substantial pollution and the production loss caused due to burst chance failure.
Pressure sealing is after leak site installs the fixture of correspondence additional, carries out blocking being allowed to form the technology being again sealed off effect by specific purpose tool and fluid sealant.The step processing this kind of situation at present in Industry system is: first finely measure leak site, and according to condition calculating deviation and swell increment to process special mould clamp, after installing fixture, fixture need to fit with end face, if there being gap, in auxiliary fixture, adding aluminum skin or copper sheet is adjusted, the leak case again occurred because of factors such as pressure due to leak site after making injecting glue is minimized, or in fluid sealant, add the tamper such as particulate matter and broken copper wire again, expect that it flow to and rest on big leakage position, gap and forms obstruction, prevent the leakage of glue, thus reach to promote the purpose of injecting glue sealing effectiveness.
Existing leakage stopping technology is to install an annular fixture additional at the flange of leak site, injects fluid sealant to fixture is internal the most again.When the space within fluid sealant fills fixture, fluid sealant flow to leak source position and pressure more than the pressure of pipeline interior media, leak source is blocked, therefore fixture must fit together perfectly with paired flange and the fluid sealant within injection just can be made not reveal, and leak source just can be blocked.But in reality, the installation of flange does not often reach the strict demand that plugging chucking tools coordinates, and the dislocation of flange and deflection situation add difficulty during leak stopping.The leakage of internal sizes when easily causing injecting glue, fixture bore seal glue laminated power do not reach pressure necessary to leak stopping, even if blocking at that time, glue laminated is on the low side causes situation about leaking again because of internal.Solution traditionally is intended to secondary injecting glue, but the fluid sealant being in inside in the case of a high temperature is the most hardened, secondary injecting glue cannot be carried out, final leak stopping is failed, reveal to pollute and lose and still continuing, the most incidentally add the difficulty that cleaning is done over again, while wasting time, also miss optimal emergency repair time.
Above-mentioned processing method wastes time and energy, and reliability is the highest, and reliability and promptness away from pressure sealing require to differ greatly, and the leakage plugging technology therefore developing a kind of replacement seems particularly critical with the above-mentioned puzzlement of basic solution.Change conventional fixture closely not need on binding face, add the mode that the mats such as copper sheet aluminum skin adjust, the auxiliary such as reinforcing body granule or tinsel fixture blocks in fluid sealant because coordinating; solve above-mentioned can not positive sealing and the problem of complex operation, have highly important meaning for national economy.
