Abstract

The utility model discloses a rotary shower nozzle comprising a spraying nozzle, a rotary sleeve, a base and a gland, wherein a rotary sleeve permanent magnet is embedded in an outward flange at the lower end part of the rotary sleeve; a base permanent magnet is embedded in an inward flange of the base; and opposite surfaces of the rotary sleeve permanent magnet and the base permanent magnet are identical. The rotary shower nozzle is a magnetic suspension rotary nozzle which is not easy to lock.

Description

A kind of rotary nozzle
Technical field
The utility model relates to a kind of rotary nozzle, especially a kind of magnetic suspension rotary nozzle.
Background technology
At present; petrochemical enterprise is the general rotary nozzle that adopts structure shown in Figure 2 when oil product is in harmonious proportion; the pressure bearing of this rotary nozzle bottom is after operation a period of time; because the precipitation of part material and medium bonding are piled up in the medium; locking especially easily can not run well shower nozzle, because of needing shutdown maintenance after the shower nozzle locking; the equipment failure rate height, efficient is low.Therefore, designing a kind of rotary nozzle that is difficult for locking, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of magnetic suspension rotary nozzle that is difficult for locking.
The technical scheme in the invention for solving the technical problem is:
A kind of rotary nozzle, by nozzle, rotary sleeve, base and gland are formed, the feed tube of nozzle is threaded with rotary sleeve, there is the twice outward flange middle part and bottom at rotary sleeve, in the gland upper end inward flange is arranged, the slightly larger in diameter of the inward flange of gland upper end is in the external diameter of rotary sleeve, the diameter of the outward flange at rotary sleeve middle part is slightly less than the diameter of gland, in the formed annular chamber of outward flange at the inward flange of gland upper end and rotary sleeve middle part, be provided with graphite cannula, rotary sleeve is by graphite cannula and gland rotation liquid sealing, there is inward flange bottom at base, the diameter of the inward flange of base bottom is suitable with the internal diameter of rotary sleeve, the diameter of the outward flange of rotary sleeve bottom is slightly less than the internal diameter of base, be provided with the circular orientation projection in the base upper surface, be provided with the detent that mates with the circular orientation projection of base upper surface in the lower surface of gland, in the outward flange of rotary sleeve bottom, be inlaid with the rotary sleeve permanent magnet, be inlaid with the base permanent magnet in the inward flange of base, the rotary sleeve permanent magnet is identical with the opposite face polarity of base permanent magnet.
Described rotary sleeve permanent magnet and base permanent magnet are permanent magnet blocks ring or circumferential equally distributed permanent magnet blocks.
Compared with prior art, the utility model in the bottom (former pressure bearing place) inlay permanent magnet device, the principle of the homopolar-repulsion by magnet, remain on suspended state when making the shower nozzle operation always, species precipitate in the medium is discharged with medium by the pressure of pipeline self, solve the problem of the easy locking of original shower nozzle, thereby reduced the maintenance of shower nozzle, had long life cycle.Through petrochemical industry respectively at diesel oil, lubricating oil, contain dirt water, carbon black liquid, heavy fuel wet goods medium and use, obtain good result of use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of prior art rotary nozzle.
The specific embodiment
As shown in Figure 1, a kind of rotary nozzle, by nozzle 1, rotary sleeve 2, base 5 and gland 4 are formed, the feed tube of nozzle 1 is threaded with rotary sleeve 2, there is the twice outward flange middle part and bottom at rotary sleeve 2, in gland 4 upper ends inward flange is arranged, the slightly larger in diameter of the inward flange of gland 4 upper ends is in the external diameter of rotary sleeve 2, the diameter of the outward flange at rotary sleeve 2 middle parts is slightly less than the diameter of gland 4, in the formed annular chamber of outward flange at the inward flange of gland 4 upper ends and rotary sleeve 2 middle parts, be provided with graphite cannula 3, rotary sleeve 2 is by graphite cannula 3 and gland 4 rotation liquid sealings, there is inward flange bottom at base 5, the diameter of the inward flange of base 5 bottoms is suitable with the internal diameter of rotary sleeve 2, the diameter of the outward flange of rotary sleeve 2 bottoms is slightly less than the internal diameter of base 5, be provided with circular orientation projection 8 in base 5 upper surfaces, be provided with the detent that mates with the circular orientation projection 8 of base 5 upper surfaces in the lower surface of gland 4, in the outward flange of rotary sleeve 2 bottoms, be inlaid with rotary sleeve permanent magnet 6, be inlaid with base permanent magnet 7 in the inward flange of base 5, rotary sleeve permanent magnet 6 is identical with the opposite face polarity of base permanent magnet 7.Described rotary sleeve permanent magnet 6 and base permanent magnet 7 are permanent magnet blocks ring or circumferential equally distributed permanent magnet blocks.
