Abstract
The utility model discloses a pressure compensating drip irrigating hose, comprising a hose body. The pressure compensating drip irrigating hose is characterized in that a grooving flow channel which penetrates the hose body is arranged in the hose body. A plurality of water inlets and water outlets are arranged on the hose body alternately in turn. The water outlet is a tongue lid-shaped structure which can be matched with the water outlet tightly. The utility model has the advantages that the irrigation is uniform; the inner blocking is prevented; the reverse suction is prevented; the pressure compensating drip irrigating hose is easy to wind and convenient for transportation and collection; the water saving efficiency is high and the operation cost is low; the pressure compensating drip irrigating hose has simple manufacturing process, which is suitable for industrialized batch production; the utility model can be imbedded under the ground to work for long, which realizes the underground drip irrigation with high water saving rate, makes the drip irrigating hose free from aging from the ultraviolet, and extends service life.
Description
Affiliated field:
The utility model belongs to a kind of irrigation installation, particularly a kind of pressure-compensated irrigate band.
Background technology:
Domestic existing drip irrigation pipe and irrigate band majority all have complicated labyrinth path and small open delivery port, and this has just brought insoluble global drip irrigation product blockage problem.The obstruction that impurity in the irrigation water, microorganism and chemical mine material etc. produce in this labyrinth path is uncontrollable, can't clean, the final service life that influences irrigation installation, particularly when once irrigating end, stem reduces pressure suddenly, can go into drip irrigation pipe (band) by suck-back at the silt at the effect lower outlet place of negative pressure.Therefore these drip irrigation equipments can not be used for subsurface irrigation.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of pressure-compensated irrigate band of avoiding internal blocking and muddy water suck-back problem is provided.
The technical solution of the utility model is: a kind of pressure-compensated irrigate band, comprise belt body, it is characterized in that: in belt body, have run through belt body collude the flute profile runner; On belt body, be crisscross arranged successively several water inlets and delivery port, and the delivery port place be can with the close-fitting tongue lid shape of delivery port structure.
The above-mentioned flute profile runner that colludes can be arc.
The above-mentioned flute profile runner that colludes can be for trapezoidal.
The utility model has the advantages that: 1. pour water evenly.2. prevent inner the obstruction.3. prevent suck-back.4. be easy to twine, be convenient to transportation, collection.5. water saving efficiency height, operating cost is low.The utility model is lower than at present general irrigate band operating pressure, and generally at 10 meters more than the head, the irrigate band of this programme can get final product operate as normal at 2-3 rice head to the operating pressure of common irrigate band.6. the irrigate band processing technology of this programme is simple, is suitable for industrialized mass production.7. the utility model can be embedded under the face of land work stably in a long term, has realized the underground drip irrigation that water-saving rate is high, and makes aging that the irrigate band avoids that ultraviolet ray brings, and increases the service life.

Embodiment:
A kind of pressure-compensated irrigate band, this irrigate band are the double-decker of both sides sealing in the zone that runner river intake-outlet is set, and runner moulding in advance before the welded steel double tube wall.As shown in Figure 1, the concentrated flow road that colludes of irrigate band is located at skin; As shown in Figure 5, the concentrated flow road that colludes of irrigate band is located at internal layer.Two kinds of forms all have the arc that runs through belt body and collude flute profile runner 2 in belt body 1, this runner deforms under the variation of inner pipe water pressure, this deformation effect the cross-sectional flow area of runner, the water yield in the time of can regulating different pressures automatically is to reach the effect of even irrigation.Several water inlet 3 and delivery port 4 are crisscross arranged on belt body, thereby make each delivery port on the irrigate band all have two water inlets to supply water, and the smooth unobstructed difficult obstruction of runner, in case stop up, can use supporting steel wire to handle easily, this is that general drip irrigation pipe (band) can't be accomplished.And the delivery port place be can with the close-fitting tongue lid shape of delivery port structure 5, this tongue lid shape water flowing out structure close automatically immediately when in pipe, forming negative pressure with, prevented that outside silt from entering delivery port, this is the most effective function that prevents outside obstruction of underground drip irrigation product.
Claims (3)
1, a kind of pressure-compensated irrigate band comprises belt body, it is characterized in that: in belt body, have run through belt body collude the flute profile runner; On belt body, be crisscross arranged successively several water inlets and delivery port, and the delivery port place be can with the close-fitting tongue lid shape of delivery port structure.
2, pressure-compensated according to claim 1 irrigate band, it is characterized in that: the above-mentioned flute profile runner that colludes can be arc.
3, pressure-compensated according to claim 1 irrigate band, it is characterized in that: the above-mentioned flute profile runner that colludes can be for trapezoidal.
