Abstract
The invention discloses a steady flow nozzle, aiming to provide a steady flow nozzle capable of ensuring spray flow to be essentially constant when pressure of a water source is not steady. The technical scheme for realizing the purpose of the invention is as follows: the steady flow nozzle comprises an upper casing and a lower casing, wherein a slider is arrange in the steady flow nozzle, and the slider consists of a stepped cylinder and a cylinder; and the diameter of the stepped cylinder is less than the diameter of a step hole in the lower casing but more than the diameter of a small hole in the lower part of the lower casing, a spring bushing is arranged on the cylinder between the inner end surface of the small hole in the lower casing and the lower end surface of the stepped cylinder, an open baffle is fixed in a hole in the lower part of the upper casing, and the open baffle is arranged opposite to the slider. Compared with the prior art, the steady flow nozzle provided by the invention has the obvious advantage that the water spray quantity is constant when water pressure is not steady.
Description
Technical field:
The present invention relates to a kind of irrigation technique, particularly a kind of current stabilization nozzle.
Background technology:
Sprinkling irrigation is a kind of water-saving result irrigation technique preferably, shower nozzle is as the critical piece of sprinkling irrigation, the quality of its performance plays an important role to the spray water reliability of quality, water-saving result and work of irrigation system, present impact driven sprinkler is by changing that nozzle is realized the adjusting of flow, range, application rate of sprinkler irrigation and the source pressure instability of reality makes above-mentioned adjusting can not satisfy good effect requirements.
Summary of the invention:
The object of the invention provides a kind of substantially invariable current stabilization nozzle of nozzle flow that makes under the source pressure labile state.The technical scheme that realizes the object of the invention is, a kind of current stabilization nozzle, comprise nozzle upper shell and lower house, it is characterized in that: a slide block is arranged in nozzle, this slide block is made up of stepped cylinder and cylinder, the diameter of described stepped cylinder less than the aperture of lower house stepped hole greater than the diameter of the small diameter bore of lower house bottom, spring housing is located on the cylinder between the lower surface of the inner face of lower house small diameter bore and stepped cylinder, and it is relative with slide block to be fixed with open closure in the hole of nozzle upper shell bottom.The present invention has the constant remarkable advantage of realization injection flow rate under the hydraulic pressure instability condition compared with the prior art.
Description of drawings:
Fig. 1 is the axial section structural representation of current stabilization nozzle of the present invention.
The specific embodiment:
With the following Examples the present invention is described in detail, nozzle has upper shell 1 and lower house 4, the external screw thread on upper shell top is threaded with sprayer body, the external screw thread on screwed hole of its underpart and lower house top matches, one slide block 2 is arranged in lower house, this slide block is made up of stepped cylinder and cylinder, the value of described stepped cylinder through less than the stepped hole diameter on lower casing top greater than the diameter of the small diameter bore of lower house bottom, between the following annular end face of the stepped cylinder of lower house lower surface and slide block, be provided with spring 3.Be fixed with open closure 6 in the lower end of upper casing body opening, the effect of this open closure is, moves on the anti-limited slip block during too small or cutout when water source hydraulic pressure to snap in the sprinkler body chamber and lose steady flow result, realizes this effect, also can on the hole wall of upper shell lower end projection be set, its effect is identical.Regime flow principle of the present invention is, when the hydraulic pressure at water source raises, pressure on the upper end of slide block face increases, the elastic force that overcomes spring moves down, till when the elastic force of spring and hydraulic balance, at this moment, slide block moves down the circulation area of the discharge orifice, bottom that has reduced slide block stepped cylinder and lower house, makes the injection flow rate of hole for water spraying 5 of nozzle constant; When hydraulic pressure diminished, spring force made and moves a distance on the slide block, has increased circulation area, reached injection flow rate and did not reduce because of hydraulic pressure descends.
