Abstract
The utility model relates to a grade flow regulator for a micro irrigation hair tube, which comprises a casing, a core body and an elastic film, wherein, a water inflow hole and a water outflow hole are arranged on the core body. The utility model is characterized in that the core body is a concentric shaft, both ends of the coaxial shaft are provided with the water inflow hole and the water outflow hole, two circular rings with different diameters are axially spaced at a water outlet, the concave surfaces of the two circular rings are provided with seal rings, a reverse thread is arranged on an axial spacing and is matched with a pressing thread cover, a water inlet is provided with two circular rings which are bigger than the water outlet, and the concave surface of the circular ring is provided with a sealing ring. The regulator can be directly arranged on the head part of a hair pipe, procedures of design and installation are simplified, investment is saved, the homogeneity of irrigation and fertilization is enhanced, the casing does not fall off and the utility model does not drip and leak.
Description
The utility model relates to a kind of slight irrigation capillary-level flow rate regulator for miniature, is specially adapted to the Flow-rate adjustment of irrigate band (pipe) stem.
" the compensation slight irrigation flow straightener " of ZL97214517.6, it comprises shell, the delivery port of core body one end and the water inlet on the irrigate band join, one rectangle groove face is arranged at the bottom of core body middle part circle, be semicircle under the groove face every the road, along the semicircle arc streamline that a control flow velocity is arranged on the road, semicircle have a concentric holes and communicate into and out of the water hole every the road adjacent.Its shortcoming is: core body is made up of two parts, when hydraulic pressure is excessive, easily water clock occurs in the middle of core body, thereby causes core body to come off.
Task of the present utility model is that a kind of core body of proposition is the integral body of an injection moulding, does not come off not water clock, and slight irrigation capillary-level flow rate regulator for miniature easy for installation.
Task of the present utility model is to realize like this, it comprises shell, the delivery port of core body one end and the water inlet on the irrigate band join, one rectangle groove face is arranged at the bottom of core body middle part circle, be semicircle under the groove face every the road, along the semicircle arc streamline that a control flow velocity is arranged on the road, semicircle have a concentric holes and advance every the road adjacent, apopore communicates, 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 two annulus of two different-diameters vertically, the concave surface of two annulus is provided with sealing ring, in axially spaced-apart place design the reverse thread that screws with the irrigate band is arranged, with reverse thread supporting be the collet threaded lid, the water inlet has two annulus greater than delivery port vertically, and the annulus concave surface is provided with sealing ring.
The utlity model has following effect: this adjuster can directly be installed in the hollow billet stem, need not calculate the simplified design installation procedure, reduce investment outlay, improve the irrigation fertilization uniformity, core body is an integral body of injection moulding, does not come off, the slight irrigation capillary-level flow rate regulator for miniature of water clock not.
Fig. 1 is a structure cut-away view of the present utility model.
Fig. 2 is the structural representation of collet threaded lid.
Fig. 3 is the shell mechanism schematic diagram.
The drawing explanation: 1. water inlet 2. annulus a 3. water stream channels 4. concentric holes 5. rectangle groove faces 6. annulus b 7. reverse threads 8. annulus c 9. delivery ports 10. screw threaded cap 11. anti-skidding ear 12. shells
Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is by film, core body, screw threaded cap 10 and shell 12 forms a whole, core body is sleeved on 12 li on shell, delivery port exposes shell 12, water inlet 1 on the core body is taper, along water inlet 1 water stream channel 3 straight-through concentric holes 4 are arranged, there is a rectangle groove face 5 middle part of core body, arc is arranged every the road in the middle of the rectangle groove face 5, along the semicircle arc streamline that a control flow velocity is arranged on the road, current are irrigated hollow billet every the road from delivery port 9 inflows of core body through semicircle from water inlet 1 ingoing stream passage 3 straight-through concentric holes 4.The characteristic core body is a concentric shafts, the concentric shafts two ends are into, apopore 1,9, the delivery port place is separated with the annulus b6 and the annulus c8 of two different-diameters vertically, the concave surface of two annulus is provided with sealing ring, the reverse thread 7 that screws with the irrigate band is arranged at the axially spaced-apart place, with reverse thread 7 supporting be collet threaded lid 10, around the collet threaded lid 10 is anti-skidding ear 11, the water inlet has two two annulus a2 greater than delivery port vertically, the annulus concave surface is provided with sealing ring, in order to strengthen the bulk strength of core body, the spy is advancing, delivery port 1,9 outer toroid faces the wall and meditates to design reinforcement.When delivery port 9 is connected with the irrigate band, utilize on the core body reverse thread 7 and screw threaded cap 10 thin wall irrigation belt and core body integral body are linked into an integrated entity, so coming off can not appear in core body and irrigate band, simultaneously, delivery port 9 also can utilize two the direct socket joint heavy wall of sealing ring drip irrigation pipe.
