AI Technical Summary

Technical Problem

The existing high-pressure nozzle has poor sealing properties and the rotation speed cannot be adjusted, resulting in increased seal loss and shortened service life, affecting the cleaning effect.

Method used

Adopt a combined ultra-high pressure self-sealing structure, including angular contact bearings, torsion springs, reduction flap, deep groove ball bearings and oil seals. Through a tapered double lock seal and a combined double lock seal structure, it combines the passive rotation of the torsion springs and reduction flap , realize effective sealing and adjustment of high-pressure fluids.

Benefits of technology

It improves the sealing performance and operating stability of the nozzle, extends the service life, and improves the cleaning effect of the nozzle by adjusting the rotation speed.

Abstract

An ultrahigh pressure spray head is composed of a spray head seat, an upper end cover, a shell, a base, an ejector pin, a jackscrew and a center shaft, a plurality of linear nozzles are installed on the spray head seat, the front end of the shell is connected with the spray head seat through the upper end cover, an angular contact bearing is arranged between the shell and the spray head seat, the rear end of the spray head seat is connected with the center shaft, the center shaft is connected with the ejector pin, and the jackscrew is connected with the ejector pin through a left rotating ring. The rear end of the shell is respectively connected with the ejector pin and the jackscrew through the base, the torsion spring, the anti-abrasion ring, the speed reduction valve, the deep groove ball bearing and the oil seal are respectively arranged between the shell and the center shaft from front to back, the water seal A is formed between the center shaft and the ejector pin and fixed on the ejector pin through the water seal top nut, and the water seal B is formed between the upper end cover and the spray head seat. The base, the jackscrew, the left rotating ring, the ejector pin and the water seal form combined ultrahigh-pressure double-lock sealing for high-pressure fluid, meanwhile, the torsion spring and the speed reducing valve rotate passively to play a role in speed control, and the combined ultrahigh-pressure double-lock sealing device has the advantages of being high in sealing performance and stable in operation.
