Embodiment 1

[0023] Refer to attached figure 1 , attached image 3 ~ attached Figure 7 , the present embodiment includes a water inlet 2 and a water outlet 3, and a flow stabilization device is provided at the water inlet 2, and the flow stabilization device consists of a cover plug 1 arranged on the water inlet and a soft washer overlappingly placed in the water inlet 7 is composed of a hard washer 5. The hard washer 5 is arranged on the inner side of the soft washer 7. The hard washer 5 is provided with a tapered hole 6 at the center, and the corresponding position on the soft washer 7 is provided with a tapered hole 6. The protruding tapered plug 8 is provided with three fan-shaped holes 11 around the tapered plug 8, and a protrusion 12 higher than the thickness of the hard washer is provided on the edge of the hard washer. When installing, one end of the tapered hole 6 of the hard washer 5 faces outwards, and the protruding conical plug 8 of the soft washer 7 is placed inward. The ...

Embodiment 2

[0025] Compared with Embodiment 1, the difference of this embodiment is that the hard washer 5 is provided with a tapered hole 6 at the central position, and the corresponding position on the soft washer 7 is provided with a protruding cone matching the tapered hole 6. Shaped plug 8 is provided with four circular holes around the protruding tapered plug 8, and a bump higher than the thickness of the soft washer is provided on the edge of the soft washer.

Embodiment 3

[0027] Refer to attached figure 2 And attached Figure 11 , compared with Embodiment 1, the difference of this embodiment is that the interface between the cover plug 1 and the main pipe 14 is provided with a conical truncated truncated truss 9 , and a pressing nut10.

Abstract

The invention provides a steady flow device for trickle irrigation, and relates to a trickle irrigation device for agriculture, particularly a steady flow device for eliminating differential pressure, and adjusting water flow in water conservation trickle irrigation, which comprises a water inlet and a water outlet. The steady flow device is arranged on the water inlet, and comprises a cap arranged on the water inlet and a soft washer and a hard washer superposed in the water inlet, wherein the a taper hole is formed on the hard washer, a convex conical plug matched with the taper hole is arranged on the corresponding position on the soft washer, holes are formed around the conical plug, and a gap is formed between the taper hole on the hard washer and the convex conical plug on the soft washer. Compared with the prior art, the steady flow device for trickle irrigation remedies the deficiency in adjusting water flow and controlling irrigation pressure, has the advantages of better steady flow effect, simple structure, simple manufacture, and is particularly suitable for large area irrigation for lands with terrain variation.

Description

Technical field: [0001] The invention relates to an agricultural drip irrigation device, in particular to a steady flow device for eliminating pressure difference and regulating water flow in water-saving drip irrigation. Background technique: [0002] At present, the drip irrigation method is widely used in water-saving irrigation in my country, especially the labyrinth drip irrigation pipeline. It is very large, so that the working pressure obtained by each section of the capillary is unbalanced, and the irrigation quality is greatly affected. In the prior art, there are many steady flow devices used to eliminate the pressure difference and adjust the water flow, such as the one disclosed in Chinese patent 200320113505.6 The steady-flow and pressure-regulating tee, including a water inlet and a water outlet, is characterized in that: a pressure-regulating sleeve is installed at the rear end of the water outlet, and the pressure-regulating sleeve is provided with a pressure-r...
