Description
Technical field
The utility model is related to industry cleaning link field, 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, there is certain gap because the developed countries such as the high-end engineering goods manufacture level of China and Europe, the United States are compared also, to being at present
Only, such domestic used product is all from external import, and it is clear that the applicant once disclosed a kind of minitype high voltage water spinning
Shower nozzle is washed, it reduces cleaning cost, reduces the dependence to external product, at the same time, further reduces rotary speed, improve clear
Efficiency is washed, is increased the service life, but its rotating part employs clearance seal, and difficulty of processing is big, and production cost is high, is unfavorable for production
The widespread adoption of product.Very big noise can be also produced during other high-pressure water jet work system work, operating personnel are good for
Health has very big harm, therefore, it is necessary to carry out noise elimination processing to this system, existing method is to carry out the protection of noise, also
It is to allow operator to wear earplug.This is, using one of method the most universal, to be imitated with simple, with low cost, noise reduction is implemented
Really good the advantages of.
The content of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art good there is provided cleaning performance, sealing
By force, a kind of water under high pressure noise reduction rotary nozzle with noise reduction.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of water under high pressure noise reduction rotary nozzle, including be drilled with the swivel head of eccentric orfice, rotating shaft assembly thereon, shell, enter
Water outlet connector, swivel head is connected by screw thread with rotating shaft assembly front end, and swivel head is hollow structure, and outer layer is titanium alloy material
Material, intermediate layer is rubber deadener；Annular step ladder type step is provided with the inside of described shell, rotating shaft assembly is installed outside
In shell, the rotating shaft assembly is made up of hollow rotary shaft, hollow clearance seal bar, and clearance seal bar is arranged on hollow rotation
In rotating shaft, rotary shaft is fixed in shell by former and later two deep groove ball bearings and a thrust bearing, the two ends peace of rotary shaft
Charge of oil is sealed, and the oil sealing at water inlet end is arranged in water inlet joint shoulder hole, and the oil sealing of the other end is arranged in shell shoulder hole,
Shell and water inlet joint are threadably secured connection.
Left between the staged rotary shaft and clearance seal bar and ordered series of numbers annular is machined with the outside of gap, and seal bar
Groove, it is quiet close between 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 using " O " shape rubber seal with plastic seal back-up ring.
Described swivel head outer layer covers have one layer of rubber sleeve.
The utility model has significant advantage and beneficial effect compared with prior art：Water jet hitting power is improved, clearly
Wash effect more preferably, structure is simpler, dismounting, replacing are more convenient；Excellent noise reduction effect, can make noise reach man-made noise mark
Standard, beneficial to widespread adoption.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the embodiment, structure, feature provided according to the utility model
And its effect, describe in detail as after.
A kind of water under high pressure noise reduction rotary nozzle as shown in Figure 1, including the swivel head 1 of eccentric orfice, rotary shaft 2 are drilled with thereon
Component, shell 3, water inlet joint 8, swivel head are connected by screw thread with rotating shaft assembly front end, and swivel head is hollow structure, outside
Layer is titanium alloy material, and intermediate layer is rubber deadener 15；The described inner side of shell 3 is provided with annular step ladder type step, revolves
Rotating assembly is arranged in shell 3, and the rotating shaft assembly is made up of hollow rotary shaft, hollow clearance seal bar 7, and gap is close
Seal bar to be arranged in hollow rotary shaft, rotary shaft is fixed outside by former and later two deep groove ball bearings 4 and a thrust bearing 6
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 in water inlet joint shoulder hole, the other end
Oil sealing 11 is arranged in the shoulder hole of shell 3, 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 relative to rotation
The transfixion of rotating shaft 2, 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
Adopt static seal part in seal bar 7 and water inlet joint 8 between hole end surface between the front end of rotary shaft 2 and the endoporus of swivel head 1
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.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
