Abstract

The invention provides a variable drip irrigation emitter and a test system, and the variable drip irrigation emitter comprises a test seat which is provided with an installation cavity, and is provided with a water inlet channel and a water outlet channel; the irrigation emitter is arranged in the mounting cavity, the irrigation emitter comprises a core body and an elastic piece attached to the peripheral face of the core body, an energy dissipation groove is formed in the peripheral face of the core body, and the elastic piece corresponds to the energy dissipation groove and covers the energy dissipation groove so as to seal and define an energy dissipation flow channel; and the energy dissipation flow channel is respectively communicated with the water inlet channel and the water outlet channel. The drip irrigation variable irrigation emitter can be directly used for hydraulic performance testing in the research and development stage of the irrigation emitter and can also be used for actual production application, the arrangement of the elastic piece enables the irrigation emitter to achieve different water outlet flows, and the elastic piece is arranged corresponding to the energy dissipation groove, so that silt can be effectively dredged and prevented from being gathered.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a drip irrigation variable emitter and a test system. Background technique [0002] The emitter is the core component of the drip irrigation system, which can eliminate the energy of the pressure water flow in the drip irrigation belt, so that the water flow can be evenly and slowly injected into the soil from the outlet. Due to the small size and complex structure of the emitter, there are few methods for testing the hydraulic performance of the emitter in the research and development stage. The following three methods are mainly used: 1. Establish a three-dimensional model and calculate the water flow of the emitter through computational fluid dynamics numerical simulation; 2. 1. Process the emitter model enlarged in equal proportion and test its hydraulic performance; 3. Open the mold and inject the emitter, use the production line to produce the drip irrigation tape e...
