Abstract

The homogeneous drip irrigation installation capable of being used for long distance and wide pressure range has in the labyrinthic drip flow channel increased pressure feedback compensating film, which has different expansion in different pressure to alter the effective flow channel area and result in homogeneous drip irrigation under long distance and wide pressure range. One elastic plastic or rubber film is attached via hot pressing or adhesion to the labyrinthic drip flow channel and its elastic expansion is used for pressure feedback compensation leading to homogeneous drip irrigation.

Description

The even drip irrigation appliance that can under the wide pressure of long distance, use
Technical field the present invention relates to a kind of drip irrigation appliance, especially the even drip irrigation appliance that can use under the wide pressure of long distance.
The background technology drip irrigation appliance is mainly used in the agricultural crops irrigation and green plants is irrigated, because the drip irrigation mode is than traditional flood irrigation mode conserve water, so the drip irrigation mode has obtained increasing application.At present, the irrigate band that the direct hot pressing of the useful plastic foil of known drip irrigation appliance forms, also useful labyrinth pipe is inserted the drip irrigation pipe that forms in the plastic tube, its basic principle is that the labyrinth flow-path that utilizes the drip place oozes after with the liquid decompression, when this mode is used under the fluid pressure variation situation greatly in long distance or in the irrigate band, the liquid that the bigger place outflow of close water source or pressure can occur is more, and the less problem of liquid that flows out away from the lower place of water source or pressure, thereby cause the inhomogeneous of drip irrigation.
Summary of the invention is in order to solve long apart from drip irrigation problem of non-uniform under the wide pressure that drip irrigation appliance commonly used occurs, the invention provides a kind of at long drip irrigation appliance apart from the even drip irrigation of energy under the wide pressure, this device increases the pressure feedback compensate film in the drip labyrinth flow-path, utilize the expanded size difference of pressure feedback compensate film under different pressures, change the valid circulation area of labyrinth flow-path, thereby make drip irrigation appliance even drip irrigation of energy under the wide pressure of long distance.
The technical solution used in the present invention is: this device is by the pressure feedback compensate film, labyrinth flow-path, drip, aperture, outlet, the irrigate band, drip irrigation pipe is formed, in the labyrinth flow-path of drip irrigation appliance, by hot pressing or bonding resilient plastics or rubber membrane are invested in the labyrinth flow-path, film formed seal cavity separates with runner, inwall near irrigate band or drip irrigation pipe in the seal cavity has an aperture that communicates with irrigate band or drip irrigation pipe, liquid in irrigate band or the drip irrigation pipe enters in the diaphragm seal by this aperture, utilize the elastic expansion effect of this film to carry out the pressure feedback compensation, when fluid pressure is big, the liquid that drip flows out increases, but because the pressure that enters in the film also becomes big, the volume that film occupies after expanding is just big, the valid circulation area of labyrinth flow-path diminishes, the liquid that drip flows out will reduce, fluid pressure hour, the liquid that drip flows out reduces, but because the pressure that enters in the film also diminishes, the smaller volume that film occupies after expanding, it is big that the valid circulation area of labyrinth flow-path becomes, the liquid that drip flows out will increase, the liquid that so just makes drip irrigation appliance ooze is constant substantially, can keep even drip irrigation substantially.
The invention has the beneficial effects as follows: by increase sealing and resilient film in labyrinth flow-path, when pressure changes, change the valid circulation area of labyrinth flow-path, thereby be implemented in the even drip irrigation under long distance and the wide pressure, apparatus structure is simple and easy to realize.
The present invention is further described below in conjunction with accompanying drawing and preferred embodiment for description of drawings.
Fig. 1 is the schematic diagram of the even irrigate band of the preferred embodiment of the present invention.
Fig. 2 is the schematic diagram of the even drip irrigation pipe of the preferred embodiment of the present invention.
1. elastic membranes among the figure, 2. labyrinth flow-path, 3. drip, 4 apertures, 5. outlet, 6. fluid, 7. irrigate band, 8. drip irrigation pipe.
Embodiment is in Fig. 1, and fluid (6) enters labyrinth flow-path (2) from drip (3), and fluid (6) passes through film (1) again and oozes from outlet (5) then, and simultaneously fluid (6) enters the space that film (1) and irrigate band (7) form through small holes (4).Liquid (6) is when pressure is big, the fluid flow that flows to outlet (5) from labyrinth flow-path (2) increases, the fluid flow that outlet (5) oozes also increases, circulation (6) is when pressure is big, and film (1) also increases with the fluid pressure in space, irrigate band (7), makes film (1) expand, the valid circulation area of labyrinth flow-path (2) reduces, the fluid flow that outlet (5) oozes is reduced, and film (1) plays the effect of a pressure feedback compensation, thereby it is uniform and stable to make the fluid of outlet (5) ooze speed.
In Fig. 2, fluid (6) enters labyrinth flow-path (2) from drip (3), and fluid (6) passes through film (1) again and oozes from outlet (5) then, and simultaneously fluid (6) enters the space that film (1) and drip irrigation pipe (8) form through small holes (4).Liquid (6) is when pressure is big, the fluid flow that flows to outlet (5) from labyrinth flow-path (2) increases, the fluid flow that outlet (5) oozes also increases, circulation (6) is when pressure is big, and film (1) also increases with the fluid pressure in drip irrigation pipe (8) space, makes film (1) expand, the valid circulation area of labyrinth flow-path (2) reduces, the fluid flow that outlet (5) oozes is reduced, and film (1) plays the effect of a pressure feedback compensation, thereby it is uniform and stable to make the fluid of outlet (5) ooze speed.

Claims (2)

1. the even drip irrigation appliance that use under the wide pressure of distance can grown for one kind, by the pressure feedback compensate film, labyrinth flow-path, drip, aperture, outlet, the irrigate band, drip irrigation pipe is formed, it is characterized in that: in the labyrinth flow-path of drip irrigation appliance, by hot pressing or bonding resilient plastics or rubber membrane are invested in the labyrinth flow-path, film formed seal cavity separates with runner, inwall near irrigate band or drip irrigation pipe in the seal cavity has an aperture that communicates with irrigate band or drip irrigation pipe, liquid in irrigate band or the drip irrigation pipe enters in the diaphragm seal by this aperture, utilizes the elastic expansion effect of this film to carry out the pressure feedback compensation.
2. the even drip irrigation appliance that can under the wide pressure of long distance, use according to claim 1, it is characterized in that: in the drip labyrinth flow-path, increase the pressure feedback compensate film, utilize the expanded size difference of pressure feedback compensate film under different pressures, change the valid circulation area of labyrinth flow-path, thereby make drip irrigation appliance even drip irrigation of energy under the wide pressure of long distance.
