Description
Technical field
The present invention relates to high pressure sealing technical field, and in particular to a kind of interior clamshell high-pressure installation.
Background technology
Application conditions of the high-pressure bottle in the fields such as oil, chemical industry, nuclear industry, coal chemical industry are increasingly harsh, high temperature, high pressure
Deng working environment and the loading such as impact, earthquake, storm it is complicated and changeable, cause requirement to pressure vessel increasingly
It is high.The important high-pressure bottle of the industrial technology department such as high-pressure bottle, especially chemical industry, oil refining and nuclear power station application, is needed mostly
To be uncapped in end to meet production technology, safety inspection and the needs for assembling and disassembling internals, therefore high pressure sealing technology is pressure
The important component of container technique；
The high pressure sealing technology of existing structure mainly includes two kinds：Forced sealing and self-energized seal, by fastener
Packing washer reaches pretension and referred to as forced sealing can be also sealed when ensureing work, sealing structure form it is common for plain cushion it is close
Envelope and Cachaly seal, into power component it is mainly kingbolt form in flat gasket, with container pressure rise and the increasing of internal diameter
Greatly, the diameter and number of kingbolt, sealing device both bulk, assembly and disassembly inconvenience and disassembly and assembly time length, Caza will necessarily be increased
Sealing replaces kingbolt to act on the packing ring of triangular-section with screw shell, due to eliminate the kingbolt structure of major diameter compared with
Compact, dismounting is also more convenient, but saw-tooth thread processing difficulties, with high costs, and required precision is high, both forced sealings
High is required to pad thrust, is not suitable for all very big occasion of temperature and pressure, because pad thrust change sensitivity is easily drawn
Play leakage；Self-energized seal is that the pressure medium inside elastic dilatation and container using sealing gasket compresses potted component realization
The mode of sealing, it is that pressure is higher the characteristics of self-tightening sealing, potted component is bigger in the thrust of contact surface, and sealing property is just
It is better, sealing is mainly had no effect under the fluctuation of pressure and temperature including seal with double-cone, wood closure, both sealing means
Reliability, but still the features such as structure bulky, part more and processing trouble be present, other are as o-ring seals, C-shaped ring sealing
Also all easily killed there is screw thread Deng sealing means, the problems such as workpiece precision is high, equipment failure rate is high, structure bulky.
Therefore need a kind of part for effectively reducing required configuration in equipment badly, reduce to workpiece precision requirement, screw thread
Be not easy to be killed, compactness not by temperature and pressure influence of fluctuations high pressure sealing technology.
The content of the invention
