Abstract

The utility model discloses the built-in flat water dropper of pressure-compensated labyrinth flow-path, comprise labyrinth flow-path, it is characterized in that: described labyrinth flow-path is located on the inwall of rectangle cover plate, be provided with in one end of rectangle cover plate and export with the flowing water of labyrinth flow-path the apopore be connected; Described rectangle cover plate fixed cap, in the mouth of rectangle uncovered box body water dropper shell, the diapire of rectangle uncovered box body water dropper shell is provided with axial water inlet flow channel, is provided with filter opening in one end of axial water inlet flow channel; The rectangle compensating plate being with limbers is provided with, the flowing water entrance of the corresponding labyrinth flow-path in position of limbers between the diapire and rectangle cover plate of rectangle uncovered box body water dropper shell.The built-in flat water dropper of this pressure-compensated labyrinth flow-path, drip irrigation pipe tube wall due to labyrinth flow-path drip irrigation pipe inwall dorsad, adds compensating plate, so can be avoided to go deep into labyrinth flow-path and affect flow simultaneously, and when variation in water pressure, flow can be kept constant.

Description

The built-in flat water dropper of pressure-compensated labyrinth flow-path
Technical field
The utility model relates to a kind of improvement of flat water dropper, belong to water-saving irrigation instrument technical field in agricultural production, specifically one can avoid drip irrigation pipe tube wall go deep into labyrinth flow-path and affect flow, and when variation in water pressure, the built-in flat water dropper of pressure-compensated labyrinth flow-path that flow can be kept constant.
Background technology
At present, in micro drip-irrigation engineering, SMD drip irrigation pipe is mostly adopted to irrigate.Use water dropper for traditional flat water dropper, this flat water dropper is holistic rectangle plate body, one end of rectangle plate body is provided with inlet opening, the other end is provided with the square groove corresponding with drip irrigation pipe apopore, labyrinth flow-path is provided with at the outer surface of rectangle plate body, the water inlet of labyrinth flow-path is connected with inlet opening, and the delivery port of labyrinth flow-path is communicated with square groove.During use, the rectangular slab external surface with labyrinth flow-path is adjacent to the pressure welding of drip irrigation pipe inwall fix, the drip irrigation pipe tube wall of relative square groove position gets water hole, like this, in drip irrigation pipe pipe, flowing water flows into labyrinth flow-path by inlet opening, then flows out from drip irrigation pipe tube wall apopore through square groove.The deficiency of this flat water dropper is: the labyrinth flow-path due to water dropper is adjacent to drip irrigation pipe inwall, and when with drip irrigation pipe pressure welding, because the wall thickness of drip irrigation pipe is different, the thickness going deep into labyrinth flow-path is just different, and then affects the water flow of flat water dropper; Meanwhile, when the pressure of water changes, also can affect the water flow of flat water dropper.
Summary of the invention
The purpose of this utility model is to provide one that drip irrigation pipe tube wall can be avoided to go deep into labyrinth flow-path and affect flow, and when variation in water pressure, the built-in flat water dropper of pressure-compensated labyrinth flow-path that flow can be kept constant.
In order to reach above object, the technical scheme that the utility model adopts is: the built-in flat water dropper of this pressure-compensated labyrinth flow-path, comprise labyrinth flow-path, it is characterized in that: described labyrinth flow-path is located on the inwall of rectangle cover plate, be provided with in one end of rectangle cover plate and export with the flowing water of labyrinth flow-path the apopore be connected; Described rectangle cover plate fixed cap is in the mouth of rectangle uncovered box body water dropper shell, the diapire of rectangle uncovered box body water dropper shell is provided with axial water inlet flow channel, be provided with filter opening in one end of axial water inlet flow channel, the position of filter opening is corresponding with the apopore of rectangle cover plate; Rectangle compensating plate is provided with between the diapire and rectangle cover plate of rectangle uncovered box body water dropper shell, one end of rectangle compensating plate is provided with limbers, the flowing water entrance of the corresponding labyrinth flow-path in position of limbers, rectangle compensating plate concora crush is in the chamber of rectangle uncovered box body water dropper shell.
The utility model is also implemented by following measure: the length of described rectangle compensating plate is 16.6mm, and width is 7.8mm, and thickness is 0.9mm; The length of described rectangle cover plate is 17.6 mm, and width is 7.8mm, and the diameter of apopore is 1.3mm; The peripheral wall length of described rectangle uncovered box body water dropper shell is 19.6 mm, and width is 9.8mm; The box body cavity length of rectangle uncovered box body water dropper shell is 17.6 mm, and width is 7.8mm, and the degree of depth is 4 mm; Described filter opening diameter is 3.8mm.
The beneficial effects of the utility model are: the built-in flat water dropper of this pressure-compensated labyrinth flow-path, due to labyrinth flow-path drip irrigation pipe inwall dorsad, add compensating plate simultaneously, so drip irrigation pipe tube wall can be avoided to go deep into labyrinth flow-path and affect flow, and when variation in water pressure, flow can be kept constant.

Detailed description of the invention
The utility model is made with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4.The built-in flat water dropper of this pressure-compensated labyrinth flow-path, comprise labyrinth flow-path 1, it is characterized in that: described labyrinth flow-path 1 is located on the inwall of rectangle cover plate 2, be provided with the apopore 3 exporting 1a with the flowing water of labyrinth flow-path 1 and be connected in one end of rectangle cover plate 2; Described rectangle cover plate 2 fixed cap is in the mouth of rectangle uncovered box body water dropper shell 4, the diapire of rectangle uncovered box body water dropper shell 4 is provided with axial water inlet flow channel 8, be provided with filter opening 5 in one end of axial water inlet flow channel 8, the position of filter opening 5 is corresponding with the apopore 3 of rectangle cover plate 2; Rectangle compensating plate 6 is provided with between the diapire and rectangle cover plate 2 of rectangle uncovered box body water dropper shell 4, one end of rectangle compensating plate 6 is provided with limbers 7, the flowing water entrance 1b of the corresponding labyrinth flow-path 1 in position of limbers 7, rectangle compensating plate 6 concora crush is in the chamber of rectangle uncovered box body water dropper shell 4, like this, by labyrinth flow-path 1 being located on the inwall of rectangle cover plate 2, and cover in the mouth of rectangle uncovered box body water dropper shell 4, make labyrinth flow-path 1 drip irrigation pipe inwall dorsad, thus avoid drip irrigation pipe inwall and go deep in labyrinth flow-path 1 and affect flow; Owing to being provided with rectangle compensating plate 6 inside labyrinth flow-path 1, when hydraulic pressure is large, rectangle compensating plate 6 is adjacent to labyrinth flow-path 1, flow is diminished, and when hydraulic pressure hour, rectangle compensating plate 6 leaves labyrinth flow-path 1, flow is made to become large, thus flow automatic regulation, make constant flow within the scope of certain value.
As improvement of the present utility model: the length of described rectangle compensating plate 6 is 16.6mm, and width is 7.8mm, and thickness is 0.9mm; The length of described rectangle cover plate 2 is 17.6 mm, and width is 7.8mm, and the diameter of apopore 3 is 1.3mm; The peripheral wall length of described rectangle uncovered box body water dropper shell 4 is 19.6 mm, and width is 9.8mm; The box body cavity length of rectangle uncovered box body water dropper shell 4 is 17.6 mm, and width is 7.8mm, and the degree of depth is 4 mm; Described filter opening 5 diameter is 3.8mm.
