Technical field
The utility model relates to a kind of water injector.
Background technology
When washing the large tracts of land subject, as often unable to do what one wishes by single nozzle, people wish to have one to have the long-pending nozzle that reaches impulsive force of big wash surface.
Technical scheme
The utility model purpose is to provide a kind of long-pending many shower nozzles of speed-regulating type rotary jet that reaches impulsive force of big wash surface that has for people.
The utility model comprises that one is supported on interior axle in the outer shaft by bearing and back-up ring, interior axle is communicated with a base that is provided with the delivery port of two symmetric arrangement at least, the delivery port radial arrangement connects nozzle by elbow on each delivery port, and elbow is rotatably connected on the delivery port; In base, connect the crescent gear pump of forming by lower plate, internal gear, external gear, eccentric bushing by pin, the outer end of crescent gear pump by back-up ring and bearing fixing between base inner wall and outer shaft.
Because nozzle is connected on the delivery port of radial arrangement turnably, when the face that forms at interior axis when nozzle centerline and delivery port center line forms a certain angle, and each nozzle is when same direction, the water that ejects arrives and is washed away object, because its reaction force, make base drive crescent gear pump, interior axle, each nozzle formation rotation, consequently: in the radius region of nozzle and the formation of interior between centers, form uniform large tracts of land water column, and, can finish the adjustment of its rotational velocity by adjusting above-mentioned angle.
For anti-sealing enters crescent gear pump, the utility model outer shaft is supported in the outer shaft by mechanical seal away from the base link, and the outer end is provided with spring, and the outer end of outer end is provided with connecting thread.
For discharging in time enters the water of mechanical seal inboard, the utility model is provided with spilled water hole on outer shaft, and spilled water hole is positioned at outside the base end, mechanical seal.
Simultaneously; the utility model is also offered the through hole that is communicated with base on the base plate of crescent gear pump; in this through hole, establish the steel ball of diameter greater than the aperture; steel ball is supported in the base by spring, the overflow valve that purpose is made up of spring and steel ball, when the rotation power that nozzle produces excessive; and the area of passage of restriction hour; when causing the pressure of pumping cavity excessive, overflow valve is opened, thereby realizes the protection of release to pump.
And also be provided with the bellmouth that is communicated with base on the base plate, cooperate taper valve core in the bellmouth, the adjusting screw(rod) that is connected with spool is by being threaded on the base, and by the O-ring seals sealing, the control valve by spool and adjusting screw(rod) are formed passes through adjusting screw(rod), can change the area of passage of restriction, realization is to the control of flow, thereby the rotating speed of control gear pump is just realized the control to the nozzle rotating speed.
