Description

The sprinkling irrigation shower nozzle that adjustable automatic windup-degree water jet is flexible automatically

The sprinkling irrigation shower nozzle that a kind of adjustable automatic windup-degree water jet is flexible automatically relates to the sprinkler irrigation technique field.

Though existing rocker-arm sprinkling irrigation shower nozzle also can rotate gradually and carry out 360 ° of sprinkling irrigations, can not realize deciding on request angle and decide direction and back and forth rotate sprinkling irrigation, be installed on the needs of spraying in the corner, plot so can not satisfy the shower nozzle of will spraying.The terrain clearance that existing in addition sprinkling irrigation shower nozzle is installed its water jet of back generally all is invariable, and when not spraying, its existence can influence the attractive in appearance of some specific environment, brings some inconvenience also can for farmland and gardens operation.

The purpose of this utility model is to provide a kind of adjustable automatic windup-degree novel sprinkling irrigation shower nozzle that only water spray eloquence is stretched out automatically when sprinkling irrigation.

The purpose of this utility model is achieved in that the expansion link of being made up of nozzle boss (1), adapter sleeve (5), sleeve pipe (7), split ring (24) etc. is housed in the inner chamber of being made up of loam cake (2), sealing shroud (3), pressure ring (19), housing (11), is with compression spring A (8) in the expansion link outside; The current impulsion rotary system of being made up of terminal pad (33), dwang (25), water wheels (28), steel ball (12), block (13), fluidic plate (15), detent cam (31), driving lever (30), pin (14), lining (29) is housed in sleeve pipe (7) lower end; Restriction orifice (16) and filter screen (32) dwang and adapter sleeve are housed in the terminal pad lower end to be integral with jump ring (21) clamping; Splicing is integral adapter sleeve with nozzle boss again; Dwang is equipped with compression spring C (27), gland (10), anti-wear gasket (9), pad C (26) with quill to contacting end face; The endoporus that compression spring B (23), pad B (22), pad A (6), water conservancy diversion cover (4) are loaded on nozzle (20) is housed between sleeve pipe and adapter sleeve; Nozzle is contained in the inclined hole of nozzle boss; Screw base (18) is pressed the apical pore that is inserted in nozzle boss (1), and its lower end plays a part axial locking nozzle.Screw (17) is loaded in the screwed hole of screw base.Turning screw adjusts its protruded length and just can realize changing the water flow jet state.Housing bottom screw thread and sprinkling irrigation water supply line are connected, after pressure flow enters inner chamber, compression spring A shortens water jet promptly along with expansion link raises meanwhile with regard to pressurized, pressure flow passes through filter screen, part current are by two metering holes aiming at two jet orifices on the terminal pad on the restriction orifice and two jet orifices on the terminal pad, and by in the two corresponding jet orifices on the fluidic plate to water wheels, make water wheels produce rotation.Under the effect of water wheels rotary centrifugal force, make outer the moving of two steel balls climbing in the water wheels groove, block two boss of dwang inner chamber, thereby drive dwang, adapter sleeve, nozzle boss rotate together.Turn to the vertical plane collision driving lever of the cam that makes the bottom when dwang, and driving lever is worked angle of fluidic plate rotation, when making on the fluidic plate in addition two jet orifices aim on the terminal pads two jet orifices, the current that spray from the jet orifice of fluidic plate make the current reverse rotation again, cause dwang, adapter sleeve, nozzle boss be and then reverse rotation also.When the dwang reverse rotation is collided driving lever to the vertical plane of using the elastic pawl fastening in the detent cam of dwang bottom straight-tooth groove, and driving lever is worked angle of fluidic plate backward rotation, current spray original two jet orifices on fluidic plate again, make water wheels recover to be rotated in the forward.Circulation repeatedly so again and again, nozzle boss delivery port back and forth rotation in the setting scope when just having realized sprinkling irrigation.Come and go rotation angle value as changing the nozzle boss delivery port, only need to change the catch positions of detent cam,, just can realize changing the nozzle boss delivery port and come and go rotation angle value to change the angle of both cam vertical planes at dwang bottom straight-tooth groove.Adjust the nozzle boss delivery port as need and come and go the rotary speed value, as long as by changing the plug-in position of filter screen on terminal pad.The current limliting aperture that so conveniently is positioned to aim on the restriction orifice of filter screen two jet orifices of terminal pad changes, and also changes thereby make from the current size of fluidic plate jet orifice ejection thereupon, and the nozzle boss delivery port comes and goes rotary speed and also changes simultaneously.Except from the current of fluidic plate jet orifice ejection, remaining current then is after converging by peripheral space inflow dwang lower end inner chamber with from the current that the fluidic plate jet orifice sprays, finally to spray two hole for water sprayings up and down from nozzle.When sprinkling irrigation stopped, along with the reduction of inner chamber hydraulic pressure, expansion link automatically retracted in the inner chamber under the returning place force effect of compression spring A.

In sum, the utlity model has and to adjust automatic windup-degree of nozzle boss delivery port and speed, can stretch out automatically during the water jet sprinkling irrigation, can withdraw automatically when stopping to spray, and the shower nozzle that can be fit to spray is installed on the corner, plot and sprays, can satisfy the requirement of some specific environment, can make things convenient for farmland and gardens operation, characteristics such as handsome in appearance.
