Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, it is a kind of that for the electrical insulation pipeline supporting component under vacuum environment, it comprises base 1, the top of base 1 is provided with cover plate 3, and base 1 is provided with ceramic insulation fastener 2 between cover plate 3, and the two ends of cover plate 3 are fixed on base 1 by separation prevention bar 4 and bolt 5.
Wherein, base 1 is that material is stainless steel in the present invention by the metalwork comprising the inside conducting structure that both sides are connected with fixing bolt, but is not limited to this in using.The size of base 1 need match with installing the basic unit's embedded part required for being connected with size, highly then can be adjusted (as 1 in Fig. 1) according to caliber and vacuum interior space size; Application on this assembly, it need weld (intermittent welding) with basic unit's embedded part, to solve the needs of problems of supporting structure intensity, plays the connection function with base material; The inside conducting structure that both sides are connected with fixing bolt, the latus rectum size of its inner passage matches with institute accepted standard bolt, and be connected with vacuum chamber, avoid the appearance of this type of bolt bearing " dead vacuum " microhabitat;
Ceramic insulation fastener 2 is made up of the tubulose fastener of upper and lower two halves, and button mouth adopts hierarchic structure to add creep age distance, serves the electrical insulation effect between metallic conduit and supporting surface, leaves certain fit tolerance, be convenient to installation and maintenance;
Cover plate 3 is platy structures of a stainless steel arc both sides strap bolt through hole, and its radian needs to carry out prefabricated according to supporting caliber, plays pipeline fixation;
Separation prevention bar 4, be that matching standard bolt uses, the head both sides spoting weld fixing bolt are outside, play protection and prevent the bolt falling problem because vibrations or electromagnetic force cause; Its one leaves a little holder handle, is convenient to need operation when removing.
The present invention is for the electrical insulation pipeline supporting component under vacuum environment, on the impact of structure, the requirement also having the aspect such as installation and maintenance and manufacturability when the structure of whole pipeline support assembly mainly considers high vacuum, electrical insulation and electromagnetic change, this assembly ensure that the realization of the support function under this kind of operating mode.It can be used for nuclear power, the industry such as Aero-Space and chemical pipeline.
The invention solves and have again in the environment of insulation requirements in vacuum, the support fixation problem of metallic conduit.By the use of rational structure and material, avoid between structural " dead vacuum ", the venting controlling material and metallic conduit and supporting surface (particularly metallic support face) due to electric discharge phenomena that potential difference easily causes; In installation and maintenance process, go back emphasis to consider in the environment having electromagnetic field to change electromagnetic force to the impact of fixed block, solve the anticreep of bolt and maintainable demand is installed, comprehensive appeal factor, the present invention substantially increases reliability and the application area of conduit support; Solve conventional pipelines supporting element easily to the destruction that vacuum environment causes; The employing of ceramic insulation fastener achieves the electrical insulation between metallic conduit and supporting surface (particularly metallic support face); The use of separation prevention bar matching standard bolt not only improves Security but also achieve the feasibility of installation and maintenance and facilitate.
