The flow channel body includes an energy dissipation body. The first drainage channel is formed in the energy dissipation body, the first drainage channel is connected to both ends of the energy dissipation body. The first drainage channel is connected at both ends of the first drainage channel to the inner wall of the elastic body forming a radial drainage channel.

Abstract: A test platform for an automatic flushing valve is described. It includes a fluid source, weighing parts, a bracket, a diverter and several driplines. The driplines are parallel to each other and are evenly arranged in an array in a circumferential direction of the diverter. Emitters are installed on each of the driplines; one end of each driplines is fixed to the diverter, which is connected to the fluid source to feed fluid into the driplines. The diverter is pivotally connected to the bracket, so that the diverter and the driplines can pivot relative to the bracket; the other end of each driplines is used to install automatic flushing valves. Weighing parts are installed below the automatic flushing valves to measure the solution flowing out of the automatic flushing valves, and other weighing parts are installed below the driplines to measure solution flowing out of the emitters.
