Abstract
The utility model discloses an inlayed-cylinder pressure compensation type drip irrigation pipe which comprises a tubular-structured body with two ends opened. One side face of the body is provided with an upper cover, a buffer space is formed between the upper cover and the body, a circular elastic film is arranged between the upper cover and the body, a water inlet is formed in the body and corresponds to the elastic film, a water outlet is formed in the upper cover, and the water outlet faces to the water inlet. What matters about the inlayed-cylinder pressure compensation type drip irrigation pipe is the elastic film; when pressure increases, holes are squeezed through the elastic film or a water-carrying section is downsized through a passageway, so that the role of flow regulation is achieved, and water yield of a water dropper is unaffected by pressure changes; when pressure is greater than the maximum working pressure of 1 kg, the water dropper no longer functions in compensation, and when the pressure is less than the minimum working pressure of 0.5 kg, the water dropper has a washing function; the principle is that the passageway or the holes have increased water-carrying area, and blockages can be washed away by the increased flow.
Description
Technical field
The utility model relates to a kind of interior edge column type pressure compensated drip pipe, belongs to this technical field of agricultural pipe.
Background technology
In agricultural irrigation process, drip irrigation technique is generally used.But the problem existing in drip irrigation process, the pressure of dropper pipe is larger, and water yield is just larger, so just cause the local irrigation water that local hydraulic pressure is large many, and the little local irrigation water of pressure is few, cause irrigation water uneven, also just brought certain waste.
Utility model content
In order to make the water yield of drip irrigation pipe not be subject to the impact of hydraulic pressure, guarantee that irrigation water is balanced, the utility model provides a kind of interior edge column type pressure compensated drip pipe.
The purpose of this utility model is carried out specific implementation by the following technical programs:
Interior edge column type pressure compensated drip pipe, comprise body in tubular construction, the both ends open of body, a side at body is provided with upper cover, between upper cover and body, forms cushion space, is provided with the flexible sheet of circular arc between described upper cover and body, corresponding described flexible sheet is provided with inlet opening on body, simultaneously cover on described and be provided with apopore, described apopore and described inlet opening, over against answering, make described flexible sheet between inlet opening and apopore.
Further, cover near described apopore and be also provided with backwater hole.
Described upper cover snaps onto on body, and the outer surface of described upper cover and the outer surface of described body maintain an equal level mutually.
The interior edge column type pressure compensated drip pipe of above-mentioned design, crucial at flexible sheet, when pressure increases, flexible sheet extrusion orifice or runner make cross-section of river size decreases, thereby reach the effect of adjust flux, the impact that the water yield of water dropper is not stressed and changes, when pressure is greater than 1 kilogram of maximum working pressure (MWP), water dropper no longer has compensating action, when being less than 0.5 kilogram of minimum working pressure power, there is pre-washing function, its principle is that the discharge area in now runner or aperture increases, and flow increases and tamper can be rinsed out.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 be described in the utility model embodiment in the structure chart of edge column type pressure compensated drip pipe.
Embodiment
As shown in Figure 1, interior edge column type pressure compensated drip pipe described in the utility model embodiment, comprise body 1 in tubular construction, the both ends open of body 1, a side at body 1 is provided with upper cover 2, between upper cover 2 and body 1, form cushion space 7, between described upper cover 2 and body 1, be provided with the flexible sheet 4 of circular arc, corresponding described flexible sheet 4 is provided with inlet opening 3 on body, on described upper cover 2, be provided with apopore 5 simultaneously, described apopore 5 over against answering, makes described flexible sheet 4 with described inlet opening 3 between inlet opening 3 and apopore 5.
Further, near the upper cover 2 described apopore 5, be also provided with backwater hole 6.
Described upper cover 2 snaps onto on body 1, and the outer surface of described upper cover 2 maintains an equal level mutually with the outer surface of described body 1.
The interior edge column type pressure compensated drip pipe of above-mentioned design, crucial at flexible sheet, when pressure increases, flexible sheet extrusion orifice or runner make cross-section of river size decreases, thereby reach the effect of adjust flux, the impact that the water yield of water dropper is not stressed and changes, when pressure is greater than 1 kilogram of maximum working pressure (MWP), water dropper no longer has compensating action, when being less than 0.5 kilogram of minimum working pressure power, there is pre-washing function, its principle is that the discharge area in now runner or aperture increases, and flow increases and tamper can be rinsed out.
Claims (3)
1. interior edge column type pressure compensated drip pipe, comprise body in tubular construction, the both ends open of body, is characterized in that, in a side of body, upper cover is installed, between upper cover and body, form cushion space, between described upper cover and body, be provided with the flexible sheet of circular arc, corresponding described flexible sheet is provided with inlet opening on body, simultaneously covers on described and is provided with apopore, described apopore and described inlet opening, over against answering, make described flexible sheet between inlet opening and apopore.
2. interior edge column type pressure compensated drip pipe as claimed in claim 1, is characterized in that, covers near described apopore and is also provided with backwater hole.
