Abstract
The utility model discloses a drop irrigation head of a columnar structure. The drop irrigation head comprises a body of a tubular structure, a pressure compensation chamber is arranged inside the position, corresponding to a water outlet, of the body, a water inlet is formed in the position, far away from the water outlet, inside the pressure compensation chamber, a pressure buffering port is formed between the water inlet and the water outlet, and an elastic membrane is arranged on the pressure buffering port and located in the pressure compensation chamber. The two sides of the pressure buffering port are provided with flanges respectively. According to the drop irrigation head of the columnar structure in the design, when pressure is high, deformation of the elastic membrane is large, and flow of the water outlet is reduced; when the pressure is low, the deformation of the elastic membrane is small, and it is guaranteed that the flow of the water outlet is stable.
Description
Technical field
The utility model relates to a kind of column structure drip head, 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, causes irrigation water inequality, has 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 irrigation water equilibrium, the utility model provides a kind of column structure drip head.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of column structure drip head, comprise the body of tubular structure, on body, the inside of the position of corresponding delivery port is provided with pressure-compensating chamber, described pressure compensation chamber interior is provided with water inlet away from the position of described delivery port, between described water inlet and delivery port, be provided with pressure buffer mouth, and being provided with flexible sheet on described pressure buffer mouth, described flexible sheet is arranged in described pressure-compensating chamber, and the both sides of described flexible sheet are respectively equipped with guiding block.
The both sides of described pressure buffer mouth are respectively equipped with flange.
The column structure drip head of above-mentioned design, when pressure is large, flexible sheet distortion is large, and the flow of delivery port is reduced; When pressure is little, flexible sheet distortion is also little, guarantees the stability of flow of delivery port.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structure chart of column structure drip head described in the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of column structure drip head described in the utility model embodiment, comprise the body 1 of tubular structure, on body 1, the inside of the position of corresponding delivery port is provided with pressure-compensating chamber 2, described pressure-compensating chamber 2 inside are provided with water inlet 3 away from the position of described delivery port 4, between described water inlet 3 and delivery port 4, be provided with pressure buffer mouth 5, and be provided with flexible sheet 6 on described pressure buffer mouth 5, described flexible sheet 6 is arranged in described pressure-compensating chamber 2, and the both sides of described flexible sheet are respectively equipped with guiding block 7, described guiding block 7 moves back and forth in order to auxiliary described flexible sheet 6.
The both sides of described pressure buffer mouth are respectively equipped with flange.
The column structure drip head of above-mentioned design, when pressure is large, flexible sheet distortion is large, and the flow of delivery port is reduced; When pressure is little, flexible sheet distortion is also little, guarantees the stability of flow of delivery port.
Claims (2)
1. a column structure drip head, comprise the body of tubular structure, it is characterized in that, on body, the inside of the position of corresponding delivery port is provided with pressure-compensating chamber, described pressure compensation chamber interior is provided with water inlet away from the position of described delivery port, is provided with pressure buffer mouth between described water inlet and delivery port, and is provided with flexible sheet on described pressure buffer mouth, described flexible sheet is arranged in described pressure-compensating chamber, and the both sides of described flexible sheet are respectively equipped with guiding block.
2. column structure drip head as claimed in claim 1, is characterized in that, the both sides of described pressure buffer mouth are respectively equipped with flange.
