CN2579525Y - Compensation refraction type micro nozzle - Google Patents

Abstract

The utility model discloses a compensation refraction type miniature nozzle, which comprises a casing body and a core body, wherein two coaxial column-shaped continuous round rings which have different diameters are arranged along the bottom surface of the middle circle of a water inlet of the core body, and the concave surfaces of the round rings are provided with a pressure regulating rubber sheet. The center of the bottoms of the concave surfaces of the round rings is provided with a water outlet hole communicated with a water outlet on the bottom surface of a rectangular groove on the other surface of the core body. The utility model is characterized in that a water inlet in a hollow cavity of the casing body is a concentric round hole, and the core body is inserted into the casing body and is in interference fit with a column-shaped continuous ring body on the front end of the water inlet of the casing body; a water outlet which faces the casing body is provided with a refraction head fixed on the casing body through a fixing rack; tapered dispersed line type refraction surfaces are evenly arrayed on the circumstance of the refraction head. The utility model has the advantages of compact structure, small volume, less material consumption, low processing difficulty, no water leakage, easy cleanness, far spray ranges, strong compensation performance, convenient installation and disassembly and convenient use. The utility model can be used in complicated terrains.

Description

Compensation refraction type mini sprinkler

(1) technical field: the utility model relates to a kind of compensation refraction type mini sprinkler, and the irrigator that is specially adapted to micro spray irrigation uses.

(2) background technology: China Patent No. is 00248687.3 " slight irrigation capillary-level flow rate regulator for miniature ", it comprises housing and core body, it is characterized in that: core body is a concentric shafts, the two ends of concentric shafts are into, apopore, the delivery port place is separated with the annulus of two different-diameters vertically, the concave surface of two annulus is provided with sealing ring, design has the reverse thread that screws with the irrigate band at the axially spaced-apart place, with reverse thread supporting be collet threaded lid, the water inlet has two annulus greater than delivery port vertically, the annulus concave surface is placed with sealing ring, and its weak point is that use China and foreign countries shell-and-core body is hard cooperation, take the sealing of spiral shell button, and function singleness can only be used for the drip irrigation pipe stem, can not use separately as irrigator.

(3) summary of the invention: task of the present utility model is to propose a kind of installation, dismounting, cleaning conveniently, is difficult for wearing out long service life, on-deformable a kind of compensation refraction type mini sprinkler.Task of the present utility model is finished like this, it comprises housing and core body, two continuous annulus of coaxial columnar that different-diameter is arranged along round bottom surface, the middle part of core body water inlet, the concave surface of annulus is placed with the pressure regulation film, the bottom centre of annulus concave surface has an apopore to communicate with the delivery port of the rectangular channel bottom surface of core body another side, it is characterized in that; Water inlet in the cavity of housing is a concentric circle holes, core body reeve housing was to win to be connected by the continuous ring body of column of core body water inlet front end, be fixed on the housing by fixed mount in the face of there is a refraction head at housing delivery port place, evenly distributed around the refraction head have the loose wire formula of taper to penetrate face.The utlity model has compact conformation, volume is little, materials are few, difficulty of processing is low, assemble easy to use, water-tight, easy cleaning, far firing range, compensatory strong, applicability is strong.

(4) description of drawings: Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of core body; Fig. 3 is the structural representation of injector head.Among the figure, 1. housing 2. fixed mounts 3. refraction continuous annulus 8. water inlets of 4. delivery ports, 5. core bodys, 6. pressure regulation films, 7. columns 9. a taper loose wire formula are penetrated face

(5) embodiment: describe embodiment in detail in conjunction with above accompanying drawing, the utility model is made up of core body 5 and housing 1, water inlet 8 front ends on the core body have a continuous annulus 7 of column, the concave surface that annulus is arranged on the core body 5, be placed with pressure regulation film 6 on the concave surface, the bottom centre of annulus concave surface has an apopore to communicate with the delivery port of the rectangular channel bottom surface of core body 5 another sides, intake-outlet in housing 1 inner chamber is a concentric circle holes, the continuous annulus 7 of 1 li column by core body 5 water inlets 8 front ends of core body 5 reeve housings is crossed to win and is connected, be fixed on the housing 1 by fixed mount 2 in the face of there is a refraction 3 at housing 1 delivery port 4 places, evenly distributed around the injector head have taper loose wire formula to penetrate face 9.This shower nozzle is that the injection moulding secondary is finished, water enters core body through water inlet 8, flowed out by delivery port 4, water is ejected in the refraction 3, by around taper loose wire formula penetrate face 9 the even loose wire of water outlet sprayed, the concentration of energy of water, the range of water is bigger, and has compensate function, stability of flow, pressure regulating performance is strong, applicable to the complex-terrain in massif district.
