Abstract
The invention provides a high pressure water noise-reduction spinning nozzle which comprises a rotary head, a rotary shaft assembly, a shell and a water inlet connector. An eccentric hole is drilled in the rotary head. The rotary head is connected with the front end of the rotary shaft assembly through threads and is of a hollow structure. The outer layer of the rotary head is made from titanium alloy materials, and a middle layer of the rotary head is made from rubber anechoic materials. Annular ladder type steps are arranged on the inner side of the shell. The rotary shaft assembly is installed in the shell. The rotary shaft assembly is composed of a hollow rotary shaft and a hollow gap sealing rod. The gap sealing rod is installed in the hollow rotary shaft. The rotary shaft is fixed in the shell through a front deep groove ball bearing, a rear deep groove ball bearing and a thrust bearing. The two ends of the rotary shaft are provided with oil seals. Compared with the prior art, the high pressure water noise-reduction spinning nozzle has the remarkable advantages and beneficial effects that water jet hitting power is improved, a cleaning effect is better, the structure is more simple, disassembly, assembly and replacement are more convent and faster, a noise reduction effect is good, noise can reach industrial noise standards, and large-range application can be achieved.
Description
Technical field
The present invention relates to industry cleaning link field is and in particular to a kind of water under high pressure noise reduction rotary nozzle.
Background technology
Water under high pressure self-rotating nozzle is a kind of efficient, multiduty water jet cleaning instrument, is that cleaning equipment is standing.So
And, also there is certain gap because China's high-end engineering goods manufacture level is compared with developed countries such as Europe, the United States, up till now for
Only, all from external import, it is clear that the applicant once disclosed a kind of minitype high voltage water spinning to domestic such used product
Wash shower nozzle, it reduces cleaning cost, reduces the dependence to external product, meanwhile, reduce rotary speed further, improve clear
Wash efficiency, increase the service life, but its rotating part employs clearance seal, difficulty of processing is big, production cost is high, be unfavorable for producing
The widespread adoption of product.In addition also can produce very big noise during the work of high-pressure water jet work system, operator are good for
Health has very big harm, therefore, it is necessary to this system is carried out with noise elimination process, existing method is by the protection of noise, also
It is to allow operator wear earplug.This is to apply one of method the most universal, has and implements simple, with low cost, noise reduction effect
The advantages of really good.
Content of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, provides cleaning performance good, and sealing is strong, tool
There is a kind of water under high pressure noise reduction rotary nozzle of noise reduction.
The present invention solves its technical problem and takes technical scheme below to realize：
A kind of water under high pressure noise reduction rotary nozzle, including being drilled with the swivel head of eccentric orfice, rotating shaft assembly, shell, water inlet thereon
Joint, swivel head is connected with rotating shaft assembly front end by screw thread, and swivel head is hollow structure, and outer layer is titanium alloy material, in
Interbed is rubber deadener；It is provided with annular step ladder type step, rotating shaft assembly is arranged on inside the shell inside described shell,
This rotating shaft assembly is made up of the rotary shaft of hollow, the clearance seal bar of hollow, and clearance seal bar is arranged on the rotary shaft of hollow
Interior, rotary shaft is fixed on inside the shell by former and later two deep groove ball bearings and a thrust bearing, and oil is installed at the two ends of rotary shaft
Envelope, the oil sealing at water inlet end is arranged on water inlet joint ladder in the hole, and the oil sealing of the other end is arranged on shell ladder in the hole, shell
It is threadably secured connection with water inlet joint.
Leave gap between described staged rotary shaft and clearance seal bar, and outside seal bar, be machined with ordered series of numbers annular
Groove, quiet close and staged rotary shaft front end and swivel head endoporus between clearance seal bar and water inlet coupler bore
The sealing structure that envelope part is combined with plastic seal back-up ring using " O " shape rubber seal.
Described swivel head outer layer covers have one layer of rubber sleeve.
The present invention compared with prior art has significant advantage and beneficial effect：Water jet hitting power improves, and cleaning performance is more
Good, structure is simpler, and dismounting, replacing are more convenient；Excellent noise reduction effect, can make noise reach industrial noise standard, be beneficial to
Widespread adoption.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment providing according to the present invention, structure, feature and its
Effect, after describing in detail such as.
A kind of water under high pressure noise reduction rotary nozzle as shown in Figure 1, including the swivel head 1, the rotary shaft 2 that are drilled with eccentric orfice thereon
Assembly, shell 3, water inlet joint 8, swivel head is connected with rotating shaft assembly front end by screw thread, and swivel head is hollow structure, outward
Layer is titanium alloy material, and intermediate layer is rubber deadener 15；It is provided with annular step ladder type step, rotation inside described shell 3
Rotating assembly is arranged in shell 3, and this rotating shaft assembly is made up of the rotary shaft of hollow, the clearance seal bar 7 of hollow, and gap is close
Envelope bar is arranged in the rotary shaft of hollow, and rotary shaft passes through former and later two deep groove ball bearings 4 and a thrust bearing 6 is fixing outside
In shell 3, oil sealing 11 is installed at the two ends of rotary shaft, and the oil sealing at water inlet end is arranged on water inlet joint ladder in the hole, the other end
Oil sealing 11 is arranged on shell 3 ladder in the hole, and shell and water inlet joint are threadably secured connection.
Rotary dynamic seal part employs the design principle of " non-contact gap sealing ", and clearance seal bar 7 is with respect to rotation
Rotating shaft 2 transfixion, rotary shaft 2 rotates with swivel head 1, there is gap between clearance seal bar 7 and rotary shaft 2, both
Between there is theoretically no CONTACT WITH FRICTION, therefore spin friction resistance very little or almost nil, service life is longer.In gap
In seal bar 7 and water inlet joint 8, between hole end surface, the static seal part and rotary shaft 2 front end and swivel head 1 endoporus between is adopted
With the mode of " O " shape rubber seal 9,14 and plastic seal back-up ring 10,13 combination sealings, sealing effectiveness is more preferable.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example is it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng all should still belong within the patent covering scope of the present invention.
