Abstract
The utility model discloses a trickle irrigation head with a chamber structure. The trickle irrigation head with the chamber structure comprises a tubular structure body, the interior of the position, corresponding to a water outlet, of the body is provided with a pressure compensation chamber, the position, far away from the water outlet, inside the pressure compensation chamber is provided with a water inlet, a pressure buffering port is formed between the water inlet and the water outlet and is provided with an elastic membrane, the elastic membrane is located inside the pressure compensation chamber, and a plurality of small chambers corresponding to the elastic membrane are formed in the body. The two sides of the pressure buffering port are provided with flanges respectively. According to the chamber structure trickle irrigation head with the design, when the pressure is large, the elastic membrane deforms greatly, and the flow in the water outlet is small; when the pressure is small, the elastic membrane deforms slightly, and the flow in the water outlet can be stable.
Description
Technical field
The utility model relates to a kind of chamber 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 chamber structure drip head.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of chamber 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 be provided with flexible sheet on described pressure buffer mouth, and described flexible sheet is arranged in described pressure-compensating chamber, and corresponding described flexible sheet is provided with several capacitors on body.
The both sides of described pressure buffer mouth are respectively equipped with flange.
The chamber 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 chamber structure drip head described in the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of chamber 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 corresponding described flexible sheet is provided with several capacitors 7 on body.
Described capacitor is in order to improve the bearing capacity of drip head.
The both sides of described pressure buffer mouth are respectively equipped with flange.
The chamber 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 chamber 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 corresponding described flexible sheet is provided with several capacitors on body.
2. chamber 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.
