Problems solved by technology

However, these flow channels are composed of straight line segments and arcs. The complexity of the flow channel boundary obtained by this method is always limited, because the constructed flow channel boundary is obtained based on Euclidean geometry theory, the flow channel Boundaries are always segmentally continuous and differentiable, so the degree of turbulence caused by the flow is also limited

Embodiment Construction

[0025] specific implementation plan

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] figure 1 , figure 2 , image 3 and Figure 4 Indicates several typical forms of labyrinth runners currently in use.

[0028] like Figure 7 Shown are the front views of two examples of the present invention, these two examples are the emitter (abbreviation fractal K emitter) with the Koch curve as the flow channel boundary line or the center line and the Minkowski curve as the flow channel boundary line or center Line emitter (referred to as fractal M emitter). In the figure, 1 is the shell of the emitter, 2 is the inlet of the emitter, 3 is the outlet, and 4 is the flow channel. Figure 8 It is a top view of the present invention.

[0029] The invention is based on the theory of fractal geometry and generates a Koch curve from a simple straight line segment as the boundary or center line of the emitter flow channe...

Abstract

The invention discloses watering apparatus applied to various water droppers and drop irrigation tubes. The aim of the invention is achieved by the use of shell, runner set in the shell, and entrance and exit communicating with two ports of the runner. It is characterized in that the borderline or centre line of the runner is a separate-shape curve or a curve with separate shape. Compared with a routing labyrinth runner, the invention's has more strong energy-reducing effect, the fluid-state index small, and has the ability to reduce pressure sensitivity of the water dropper, and is wider than the routing labyrinth runner, sand-carrying ability strong and has very strong anti-jamming ability.

Description

technical field [0001] The invention relates to an irrigator used on various drippers and drip irrigation pipes, which belongs to the field of irrigation equipment. Background technique [0002] Drip irrigation is a modern high-efficiency irrigation technology. It can integrate irrigation and fertilization, supply water and fertilization to crops in a timely and appropriate amount, and provide a suitable growth environment for crop growth, so as to achieve high yield, high quality and high efficiency. The emitter is a key component of the drip irrigation system, and the hydraulic performance of its flow channel directly determines the working effect of the drip irrigation system. Since the underground irrigation experiment conducted by the Germans using drainage tile pipes in 1880, the form of the emitter has gone through development stages such as the orifice type, the hairline long flow channel type, and the labyrinth long flow channel type. The performance of the emitter ...
