Abstract

The invention belongs to the field of drip irrigation irrigators, and in particular relates to a star-shaped labyrinth flow channel drip irrigation irrigator. In order to reduce the flow state index to improve hydraulic performance, the invention comprises a body, and the body is provided with a water inlet and a water outlet, the water inlet and the The water outlets are connected by an energy dissipation channel. The energy dissipation channel includes several energy dissipation channel units connected in series. Each unit includes a trapezoid structure unit and a star structure unit. The shape of the trapezoid structure unit is an isosceles trapezoid. , an isosceles trapezoid is provided with an inlet on one inclined surface and an outlet on the other inclined surface; a star-shaped structural unit is arranged in the center of the trapezoidal structural unit, and the star-shaped structural unit is a center-symmetric structure, which consists of four arc-shaped curved surfaces. The four arc-shaped curved surfaces are all concave toward the center of the star-shaped structural unit, and the connecting lines of the four vertices of the star-shaped structural unit are distributed horizontally and vertically.

Description

technical field [0001] The present invention relates to an irrigator, in particular to a star-shaped labyrinth flow channel drip irrigation irrigator. Background technique [0002] Drip irrigation is an advanced and effective water-saving irrigation technology in modern agriculture. It is widely used in the irrigation of cash crops such as melons, fruits, vegetables, and cotton. The drip irrigation irrigator is the core component of the entire drip irrigation system. Its main function is to realize energy dissipation and steady flow through several flow channel structural units inside the irrigator, so that the water flow under different pressures can enter the irrigator with a uniform and stable small size. Irrigation in the form of flow. Hydraulic performance is one of the important indicators to evaluate the pros and cons of drip irrigation emitters. Generally, the quantitative evaluation is carried out by the flow state index, which reflects the sensitivity of the flow ...
