Oil emulsion is replaced using water, on the one hand reduces use cost, on the other hand reduces pollution of the oil emulsion to environment, and
The bottom of at, antirust work is carried out in 17 inner surface of cylinder, 18 outer surface of movable post, prolongs the service life.
4 inner wall of movable post mounting hole is additionally provided with magnetic gasket 5, and the magnetic gasket 5 is set in annular groove,
Sealing frame 6, permanent magnet 7 including fitting annular groove inner wall setting, buckplate 8, it is recessed that the buckplate 8 is set to annular
Close to 18 side of movable post in slot, and the first cavity 9 is formed between movable post 18, magnetic liquid, buckplate are filled in the first cavity 9
The second cavity 11 is formed between 8 and sealing frame 6, and magnetic liquid is filled in the second cavity 11；It is recessed that the permanent magnet 7 is bonded annular
What slot madial wall slided up and down is set in the second cavity, and there are gaps between buckplate 8, are provided with 10 one end of antifreeze plate
Permanent magnet 7 is connected, the other end is connect with the groove of buckplate 8, and antifreeze plate 10 is slided up and down with permanent magnet 7.
Magnetic gasket 5 is for the sealing between handle body 1 and movable post 18.Using the sealing principle of magnetic liquid, permanently
The upper end of magnet 7 sends out magnetic liquid of the magnetic induction line by top in the second cavity 11, then passes through the magnetic liquid in the first cavity 9
Body, then by the magnetic liquid of lower section in the second cavity 11, flux loop finally is formed between the lower end of permanent magnet 7,
Magnetic liquid in movable post 18, forms magnetic seal ring in the first cavity 9 connection buckplate 8, magnetic seal ring number depend on
The number of tongue and groove on buckplate 8.When movable post 18 is slided, the deformation of magnetic liquid and magnetic liquid are pulled away, and are easily caused
The critical voltage endurance capability of magnetic liquid declines, and causes to seal micro- leakage, when this phenomenon occurs, changes of magnetic field, permanent magnet 7 and every
Magnetic sheet 10 is slided up and down with changes of magnetic field, although displacement is very subtle, sufficiently achieves balance, stabilizing magnetic field makes the first cavity 9
Magnetic liquid restores its leakproofness again.
5 top setting of magnetic gasket also has the first y-type seal ring 12, and Open Side Down for the Y types of the first y-type seal ring 12,
5 lower section of magnetic gasket is provided with the second y-type seal ring 13, and the opening upwards of second y-type seal ring 13 are described
The lower section of the second y-type seal ring 13 be additionally provided with third y-type seal ring 14, the Y types of the third y-type seal ring 14 be open to
Under.First y-type seal ring 12 and the second y-type seal ring 13 are mainly used for the secondary seal to magnetic gasket 5, due to movable post
18 do is to move back and forth, therefore the magnetic liquid in the first cavity 9 is likely to leak from top, lower section, so the first Y types
The Y types of sealing ring 12 and the second y-type seal ring 13 are open towards magnetic gasket 5.And third y-type seal ring 14 is mainly used
Sealing between enhancing movable post 18 and handle body 1, since bottom cylinder is in lower section, the Y types of setting third y-type seal ring 14 are opened
Mouth is downwards.
Multiple explanatory embodiments spoken of in the present specification refer to the concrete structure packet for combining embodiment description
