Description
Technical field
The present invention relates to flange technical field, particularly relate to a kind of radioprotective blind flange.
Background technology
Flange is a kind of fastening means, and Flange joint refers to be connected with each other as one group by flange, pad and bolt three
The releasable connection of combined sealing structure.Flange divides threaded (screwed connection) flange, welded flange and clip flange.Flange is even
Connect because its connection sealing is good, stabilized structure, intensity are high, easy to use, low cost and other advantages, be widely used in building row
Industry, urban water supply, boilers and pressure vessel, petroleum industry, supply, chemical industry, grocery trade, fire-fighting, pharmaceutical industry, power station, water
The industries such as profit, HVAC.Blind flange is the one in flange, is usually and is used for blocking pipe end.When blind flange uses in core work
In industry, when having the pipe plugging of nuclear material to inside, it is desirable to blind flange has radiation-resisting functional, existing blind flange does not possesses
This function.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of radioprotective blind flange, good airproof performance, the most also has relatively
Good radiation-resisting functional, meets the closure requirement of nuclear material pipeline.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of radioprotective blind flange, bag
Include: be fixed on the flange circle of pipe end, solid ring flange body and gasket seal, solid ring flange body and the one of flange circle
