Abstract

An embedding pressure-compensation flat dripper that can perform the stream pressure compensation consists of a dripper body [figure 1(1)], an elastic membrane [figure 1(2)] and a dripper tablet [figure 1(3)]; the dripper body primarily comprises a stream inlet [figure 2(4)], an eddy-flow channel [figure 2(5)] and a pressure compensation area [figure 2(6)]. The assembling of the dripper and the dripper tablet adopts the pressing-clamping way. When in irrigation, due to the effect of the pressure compensation area, the area of the cross section of the dripper outlet is variable along with the variation of the stream pressure inside the hollow billet, thereby enabling the stream flow of the dripper to be controlled within the operation pressure range to meet the requirement of the stream-flow deviation. The dripper is primarily used for the irrigation on the farmland and the garden where have complicate landforms.

Description

The flat water dropper of internally-inlaid pressure compensation
Affiliated technical field
The utility model relates to the used water dropper of internally-inlaid drip irrigation pipe in the drip irrigation system, especially can make the water dropper flow satisfy the requirement of flow deviation in current rated operating pressure scope.
Background technology
Drip irrigation over past ten years, has obtained faster development in China as emerging water-saving irrigation technique.Water dropper is as the key equipment of drip irrigation system, and its effect is with after the pressure flow energy dissipating in the hollow billet, evenly and stably splashes into soil, makes the best saturation state of crop soil conservation.The employed flat water dropper of internally-inlaid drip irrigation pipe of domestic production at present all is non-pressure compensating emitter, and when water flow pressure changed, the water dropper flow particularly in the massif area, can't guarantee the uniformity and the uniformity of flow along with changing.
Summary of the invention
In order to overcome inhomogeneities and the inconsistency of water dropper flow when pressure changes, the utility model provides a kind of internally-inlaid pressure compensation flat water dropper, and the flow of this water dropper satisfies the flow deviation requirement in current rated operating pressure scope.
The technical scheme that its technical problem that solves the utility model adopts is: the pressure compensation district is set in the cavity of water dropper, in the pressure compensation district, flexible sheet is housed, when the pressure flow in the hollow billet acts on the flexible sheet, diaphragm will produce strain, and the water outlet cross-sectional area is changed.The pressure difference, the distortion difference of diaphragm, the water outlet cross-sectional area is also different, and the water dropper flow remains unchanged when water flow pressure changes substantially like this.
Description of drawings

Fig. 2 is the front view of water dropper body of the present utility model.

Specific implementation method
The flat water dropper of internally-inlaid pressure compensation is made up of water dropper body [Fig. 1 (1)], flexible sheet, [Fig. 1 (2)], water dropper compressing tablet [Fig. 1 (3)].
When irrigating, the pressure flow in the hollow billet enters the water dropper body by the water inlet on the water dropper body [Fig. 2 (6)], is filtered by filter window, and dirt is filtered outside water dropper, makes water dropper be difficult for stopping up; After pressure flow entered water dropper, most of current entered turbulent runner [Fig. 2 (7)], carried out energy dissipating through turbulent runner.Runner adopts the profile of tooth runner, becomes turbulent condition during current; Current after the energy dissipating enter pressure compensation district [Fig. 2 (8)], flow out through apopore [Fig. 2 (11)].The fraction pressure flow enters in the runner of water dropper compressing tablet [Fig. 1 (4)] in addition, and current produce pressure to diaphragm.When water flow pressure during less than design work pressure, diaphragm produces distortion very little (Fig. 1), and the water dropper flow changes with the variation of pressure size; When water flow pressure increases to certain value, promptly enter after the rated operating pressure, current flow out with certain design discharge.Along with the increase of pressure, diaphragm produces distortion and increases (Fig. 2), and flow velocity increases in this moment runner, but the cross-sectional area of delivery port reduces, and flow is remained unchanged substantially; When water flow pressure increases to rated operating pressure when above, the runner cross-sectional area of delivery port reduces to very little (Fig. 3), and flow reduces.Like this in the rated operating pressure scope, the flow of the flat water dropper of internally-inlaid pressure compensation, when water flow pressure changed, water outlet was uniform and stable, satisfied the requirement of flow deviation.
The assembling form of water dropper and water dropper compressing tablet adopts pressure-cliping.During assembling, the water dropper compressing tablet directly is pressed in the water dropper, relies on the boss in the water dropper chamber to be pressed on [Fig. 1 (5)] in the water dropper chamber.This simple in structure, reliable, be easy to the assembling.
Drip irrigation pipe with the flat water dropper of internally-inlaid pressure compensation is produced is applicable to the irrigation of various crops and various MODEL OVER COMPLEX TOPOGRAPHY.
