Detailed description of the invention
Embodiment 1:
As shown in Figure 1, the water under high pressure self-rotating nozzle that the utility model provides includes water outlet connector 6, water inlet joint 6 is fixedly connected with seal shaft 5 by screw thread, seal shaft 5 penetrates in rotational shell from rotational shell 4 rear end, gap is left between rotational shell 4 and seal shaft 5, and be processed with ordered series of numbers annular groove (see Fig. 4 and Fig. 5) outside seal shaft 5, the hermetically-sealed construction that static seal part between seal shaft 5 and water inlet joint 6 endoporus adopts " O " shape rubber seal 7 and plastic seal back-up ring 8 to combine, the front end of rotational shell 4 by screw thread be connected magnetic assembly 3 and be fixedly connected with, rotational shell 4 is drilled with the spray orifice 10 being eccentric in rotational shell 4 central axis, connect magnetic assembly 3 and be outside equipped with linear brake part 2, the front end of seal shaft 5 is through gland 1, by bolt 15, gland is fixed, and connection magnetic assembly 3 and linear brake part 2 are coated in gland 1, gland 1 arranged outside has bearing 12, in the utility model, seal shaft 5 center is provided with the passage 9 of hollow, water inlet joint 6 after connection connects with the passage 9 at seal shaft 5 center, meanwhile, the through hole by being provided with on seal shaft 5 makes the spray orifice 10 on water inlet joint 6, seal shaft 5 central passage 9 and rotational shell 4 form through aquaporin excessively.In addition, owing to being processed with ordered series of numbers annular groove outside seal shaft 5, making water when entering the spray orifice 10 on rotational shell 4 through seal shaft 5, reducing circulating resistance, and between seal shaft 5 and rotational shell 4, form moisture film, play the effect reducing seal shaft 5 and rotational shell 4 frictional force.Meanwhile, when containing small impurity in water, can discharge smoothly through the annular groove be provided with, also playing the protective effect to seal shaft 5 and rotational shell 4.
Described have employed " permanent magnet turbine limit speed for braking condition " technology in rotating speed control, namely, an annular is installed in the front end of rotational shell 4 and has connected magnetic assembly 3, connect magnetic assembly 3 and be outside equipped with linear brake part 2, when linear brake part 2 transfixion, when connection magnetic assembly 3 rotates with rotational shell 4, electromotive force and eddy current is produced in linear brake part 2, by the interaction of eddy current magnetism and magnetic field of permanent magnet, produce tangential braking moment, thus form speed limit (see Fig. 2 and Fig. 3).
The utility model is a kind of water jet cleaning instrument that high-pressure wash is commonly used, and main advantage is:
The utility model is structurally more perfect, and shell 4 is without the need to bearings and with magnetic force speed limiting function, and whole shower nozzle outward appearance is simpler, compact, and dismounting is more convenient, and maintenance cost is lower, longer service life.
The design principle of " non-contact gap sealing " is have employed in rotary dynamic seal part, clearance seal axle 5 is relative to rotational shell 4 transfixion, rotational shell 4 rotates, gap is there is between clearance seal axle 5 and rotational shell 4, there is not CONTACT WITH FRICTION in theory between the two, therefore spin friction resistance is very little or almost nil, longer service life.Static seal part in clearance seal axle 5 and water inlet joint 6 between hole end surface have employed the mode of " O " shape rubber seal 7 and plastic seal back-up ring 8 combination sealing, and sealing effectiveness is better.
" permanent magnet turbine limit speed for braking condition " technology is have employed in rotating speed control, namely, one annular is installed in rotational shell 4 front end and has connected magnetic assembly 3, connect magnetic assembly 3 and be outside equipped with linear brake part 2, when rotational shell 4 rotates, in the linear brake part of gland 1 rear end 2, produce electromotive force and eddy current, by the interaction of eddy current magnetism and magnetic field of permanent magnet, produce tangential braking moment, thus form speed limit.
The course of work of the present utility model:
See Fig. 6, water under high pressure flows into rotational shell 4 after right-hand member water inlet joint 6 enters clearance seal axle 5, and the spray orifice 10 then above rotational shell 4 sprays.In whole rotary-jet process, the parts such as water inlet joint 6, clearance seal axle 5, linear brake part 2, gland 1, bearing 12 are all geo-stationary, rotational shell 4 rotates, the spray orifice 10 that its revolving force comes from above rotational shell 4 is eccentric in axis, the moment of torsion produced during injection, shower nozzle belongs to spinning, does not need extra power to drive.As the embodiment of the best, spray orifice 10 in the utility model above rotational shell 4 is preferably two right, this spray orifice 10 is by the symmetrical setting of central axis of rotational shell 4, when water is outwards sprayed by symmetrical spray orifice 10, rotational shell 4 will be made to produce horizontal shearing force because of the jet-action of water, the rotation of rotational shell 4 is had an impact.Certainly, it is two right that the setting of this spray orifice 10 is not limited to, and can arrange according to concrete needs.
