Abstract
The utility model provides a compensating type turbulent drip irrigation pipe. The basic structure of the utility model comprises the main body of the drip irrigation pipe, and an embedded labyrinth sleeve pipe dripper. Water inlet grating grid holes and labyrinth flow channels are arranged on the sleeve pipe dripper. The labyrinth flow channels are arranged in the shape of stagger fishbone prominences. The end point of the fishbone is provided with circular prominences, and a constant pressure flow path compensating device is embedded at the outlet of labyrinth flow channels. The compensating device designed by the utility model has the function that the flow path is adjusted automatically following pressure variation and has a constant stable dripping characteristic. The utility model is especially suitable for high efficiency agricultural extension application in greenhouses.
Description
The utility model relates to a kind of compensation turbulent drip irrigation pipe, is particularly useful for the booth slight irrigation, belongs to gardening irrigation installation assembly.
In recent years, micro irrigation technology has obtained very fast development at world wide, the irrigation method of irrigation system has drip irrigation, little spray, infiltrating irrigation, pulse filling etc., wherein the planform kind of drip irrigation pipe is a lot, as tubular type water dropper outer surface is processed into back-shaped labyrinth groove, be inlaid in the embedded labyrinth type drip irrigation pipe in the drip irrigation pipe; Water dropper is processed into sawtooth shape flow passage and comb shape water inlet rectangular flat, is connected on SMD drip irrigation pipe on the drip irrigation pipe inwall by thermocompression bonded; By the banded maze flow passage drip irrigation belt of plastic film adhering and pressing etc., the common problem of existence is that to drip fast runner design narrow because of control, easily stops up, and needs to cooperate the filter of higher order number (more than 200 orders) to use, and it is higher to apply cost.Above-mentioned typical drip irrigation pipe all belongs to quantitative streaming and oozes, and the uniformity of dripping is bigger with pressure oscillation, the different variations of ground level, only is fit to contour layout, and isobaric water supply limited the scope of application.
The purpose of this utility model is to provide a kind of compensation turbulent drip irrigation pipe of new structure, in order to improve the motion state of current in drip irrigation pipe, prevents to stop up, and the uniformity that " constant voltage flow path " compensator drips with raising is set in pipe simultaneously.
The technical solution of the utility model is achieved in that this compensation turbulent drip irrigation pipe, basic structure comprises drip irrigation pipe main body and embedded labyrinth type sleeve pipe water dropper, establish water inlet comb hole on the sleeve pipe water dropper, labyrinth flow-path, described labyrinth flow-path is staggered fishbone bump array, the fish-bone end points has circular protruding, is embedded with constant voltage flow path compensator in the exit of labyrinth flow-path.
The labyrinth flow-path of described turbulent drip irrigation pipe not sleeve pipe is made as a row, two rows or three row's series connection.
The constant voltage flow path compensator of described compensation turbulent drip irrigation pipe comprises a flute profile base that the inlet opening is arranged, and is embedded in flexible sheet and constrictor on the base, and the contact-making surface of constrictor and flexible sheet has the water outlet groove.
The utility model is owing to the end points at the fish-bone labyrinth flow-path has designed circular protrusion, make current by the time be turbulent condition, the runner design is widened, the anti-blocking performance of drip irrigation pipe increases substantially, to relax with water quality is that 80 orders filter, and changes the function of adjusting flow path automatically, persevering characteristics of surely dripping because the compensator of the utility model design has with pressure simultaneously, demonstrate very strong competitive advantage, be particularly useful for the booth high-efficiency agriculture and apply.
Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the cutaway view of the utility model structure
Fig. 2 is the expanded view of Fig. 1
Fig. 3 is the A-A figure of Fig. 1
Fig. 4 is the B-B figure of Fig. 1
Fig. 5 is the C-C figure of Fig. 1
Among the figure: 1, circular protruding 10, the constant voltage flow path compensator 11 of drip irrigation pipe main body 2, labyrinth type head pipe water dropper 3, drip irrigation hole 4, labyrinth flow-path 5, water inlet comb hole 6, turbulent flow, compensator base 12, flexible sheet 13, constrictor 14, compensator inlet opening 15, compensator water outlet groove
Operation principle of the present utility model is: water enters the labyrinth flow-path 4 of staggered fishbone bump array from the comb hole 5 that intakes, end at labyrinth flow-path enters compensator inlet opening 14, when hydraulic pressure increases, deformation takes place to constrictor 13 in flexible sheet 12, exhalent canal concentrated flow on the constrictor is directly diminished, keep quantitative water to ooze by drip irrigation hole 3.
