Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of embodiment that the utility model is provided：A kind of electromagnetic type pressure bonnet, including inside
For the lid 1 and hollow shell 2 of hollow-core construction 3, the lid 1 is provided with interior in the region positioned at the bottom of hollow-core construction 3
Helicitic texture 4, the lid 1 is provided with spacing preiection structure 5, the spacing preiection structure 5 at the middle part positioned at hollow-core construction 3
Basal surface adhere to a seal washer 6, the center of the upper surface of the lid 1 is fixed with the hollow-core construction 2, the hollow knot
The iron core 11 that coil 10 is wound with outside one is inlayed in the inside of structure 2, and the hollow shell 2 is in the underface positioned at the iron core 11
Hollow zone of action 7 is provided with, the spacing ring that permanent magnet 8 is socketed with an inner ring is installed in the inside of the hollow zone of action 7
Multiple through-hole structures are provided between 9, and the upper and lower surface of the spacing ring 9, the hollow shell 2 and the iron core 11
It is provided centrally with connecting the hollow zone of action 7 and extraneous steam vent 12.
The spacing preiection structure 5 is cirque structure, so that while it can play spacing, do not interfere with again
The proper flow of air；The control signal of the coil 10 connects the control output end of a current regulator by wire, real
Now to effective control of coil 10；The structure radius of the hollow zone of action 7 and the structure radius phase of the outer shroud of the spacing ring 9
Together, prevent gas from leaking；The permanent magnet 8 is made up of Nd-Fe-B permanent magnet material, and this kind of permanent magnet magnetism and mechanical property are more
It is good.
Specifically used mode：In utility model works, the device is screwed in the connector of apparatus by female thread structure 4
Place, then injects the electric current of orientation by current regulator to the inside of coil 10 so that the two ends of iron core 11 produce magnetic, root
According to identical charges repel each other the principle that there is a natural attraction between the sexes, both are made to produce repelling each other effect, now, just can be by adjusting current regulator change
The size of electric current, and then change the maximum amount of the device institute control pressure, when apparatus internal pressure is more than the numerical value, permanent magnetism
