Detailed description of the invention
As depicted in figs. 1 and 2, temperature super-conducting magnet system vacuum explosion-proof device of the present utility model,
It is connected to fixing base plate including the fixing base plate 2 being connected with vacuum chamber 3 with by guiding fixing bolt 8
Pressure release block 6 on 2, described fixing base plate 2 is provided with pressure release block mounting groove, described pressure release block 6
Circumference and the fixing base plate 2 part in described pressure release block mounting groove between be provided with circumferential seal
Circle 5, described pressure release block 6 is towards between one end end face and the end face of fixing base plate 2 of fixing base plate 2
Being provided with end-face seal ring 4, described guiding fixes to connect on bolt 8 adjusting nut 7, described tune
Between leaving between the end face of bolt head one end that joint nut 7 and pressure release block 6 fix bolt 8 towards guiding
Gap.
As it is shown in figure 1, in the present embodiment, on described fixing base plate 2, the side away from vacuum chamber 3 is solid
Determine connection and have exhaustor 1.After exhaustor 1 can be used for explosion, the surge guard of air-flow and pressure release block 6 rush
Hit protection, pipe when being embodied as, can be used.
In the present embodiment, described fixing base plate 2 welds with vacuum chamber 3.When being embodied as, described solid
Determine base plate 2 to be connected by bolt is fixing with vacuum chamber 3, and at fixing base plate 2 and vacuum chamber
Sealing ring is set between 3, prevents from revealing.
As in figure 2 it is shown, in the present embodiment, it is four that described guiding fixes the quantity of bolt 8, accordingly
The quantity of described adjusting nut 7 is four.
When being embodied as, the size in the gap left between described adjusting nut 7 and pressure release block 6 end face
Design-related, principle is to ensure that pressure release when, and pressure release block 6 is washed open by pressure in vacuum chamber 3,
Can seal failure be as the criterion until pressure release block 6 moves to circumferential seal circle 5.
When being embodied as, pressure release block 6 material is generally the metal material that aluminium alloy isodensity is less, also
Can with the bigger such as rustless steel etc. of density, but be to ensure that when explosion, internal pressure can be smooth
Wash pressure release block 6 open, be reliably completed pressure release.
This utility model can be used in the safety device of cryogenic magnet vacuum chamber, it is also possible to for it
Its pressure vessel vacuum chamber is the safety device under negative pressure state.During use, fixing base plate 2 is connected
After on vacuum chamber 3, circumferential seal circle 5 is contained in described pressure release block mounting groove, then puts end face well
Sealing ring 4, then loads pressure release block 6 described pressure release block mounting groove, and manually makes pressure release block 6
It is adjacent to vacuum chamber 3, then loads onto adjusting nut 7 and guide fixing bolt 8, regulating adjusting nut 7
The distance of distance pressure release block 6 end face, exhaustor 1 can fill as required and can not fill；When in vacuum chamber 3
Air pressure is gradually become malleation by negative pressure, and when exceeding certain value, under pressure, pressure release block 6 quilt
Push to outside vacuum chamber 3, until pressure release block 6 end face stops after contacting with adjusting nut 7 so that end
Face seal circle 4, the sealing effectiveness of circumferential seal circle 5 lost efficacy, so that vacuum chamber 3 pressure is rapid
Release, and then reach explosion-proof purpose.
The above, be only preferred embodiment of the present utility model, not makees this utility model any
Limit, every according to this utility model technical spirit, above example is made any simple modification,
Change and equivalent structure change, all still fall within the protection domain of technical solutions of the utility model.
