Description
Technical field
The present invention relates to a kind of sealing configuration, be particularly useful for the sealing in water joint.
Background technique
At present, what the sealing configuration in water joint adopted substantially is traditional seal ring seal, the various types seal ring seal is the contact-type packing seal, on static element, process dovetail groove, seal ring is circularized or is with shape by metric system, be placed in the dovetail groove and contact, play seal action with the axle driving fit.There are a lot of problems in seal ring seal, and frictional resistance moment is big, the life-span of seal ring is very short, sealing reliability is lower, seal ring is easily by aqueous corrosion, causes seal failure.
Summary of the invention
The objective of the invention is to overcome that existing water joint seal ring seal frictional resistance moment is big, the seal ring life-span is short, cause seal failure, the withstand voltage low deficiency of sealing after seal wears or the corrosion, a kind of aqueous joint seal structure is provided.
Technological scheme of the present invention:
A kind of aqueous joint seal structure comprises: be supported on hollow shaft and black box in two bearings that are installed in the shell.The sealing assembly by the little pole shoe in the right side, first magnet, first pole shoe, second magnet, second largest pole shoe, the 3rd magnet, the third-largest pole shoe, the 4th magnet, the fourth-largest pole shoe, the 5th magnet, the fifth-largest pole shoe, the 6th magnet, left little pole shoe is bonding successively forms.
After the endoporus of first magnet, second magnet, the 3rd magnet, the 4th magnet, the 5th magnet, the 6th magnet injects magnetic liquid, black box is installed between left bearing and the right bearing.
With locking nut black box is fixed on the hollow shaft; The above-mentioned hollow shaft that black box is installed is installed in the enclosure, with being threaded on nut and the shell.
The shape of the little pole shoe in the described right side, first pole shoe, second largest pole shoe, the third-largest pole shoe, the fourth-largest pole shoe, the fifth-largest pole shoe, left little pole shoe is a hollow cylindrical, the processing of utmost point tooth is at the inwall of cylindrical body, the outer wall of cylindrical body is processed with seal groove, and seal ring is installed in each seal groove.
The shape of described first magnet, second magnet, the 3rd magnet, the 4th magnet, the 5th magnet, the 6th magnet is a hollow cylindrical.
One end of described hollow shaft is established screw thread, processes a boss near flange end.
Described magnetic liquid is the oil base magnetic liquid.
The beneficial effect that the present invention compared with prior art has:
The present invention replaces with magnetic fluid sealing with the seal ring seal in Yuan Shui joint, make the reliability of water joint sealing increase, sealing can not lost efficacy because of the wearing and tearing of seal ring or corrosion, the ILS of sealing, the frictional resistance moment of sealing reduces, friction power loss reduces, and seals withstand voltage increase, can reach 10atm.
