Abstract

The invention discloses a sliding block reversing jet flow tee joint and pulse micro-irrigation system, and belongs to the technical field of agricultural irrigation, the sliding block reversing jet flow tee joint and pulse micro-irrigation system comprises a water pump, a fertilizing device, a filtering device, a main pipe, branch pipes, capillary pipes, jet flow pulse tee joints, capillary pipe joints, drippers, valves, branch pipe joints and main pipe joints; pressure water flow enters the jet space through the jet pipe to form jet, and the wall attachment effect is generated. A sliding block air pressure reversing device is arranged, the atmospheric pressure acting direction is periodically changed, and the jet flow direction is periodically and alternately changed. The jet flows are switched and flow in the jet flow pulse tee joint according to a certain frequency, pulse water flow is generated and enters a pipeline of the micro-irrigation system, strong turbulent fluctuation and impact water flow are formed in the irrigation emitter, and the anti-blocking capacity and the irrigation uniformity of the micro-irrigation system are enhanced. The jet pulse tee joint is more stable in jet reversing, pulse parameters can be designed according to needs, and the jet pulse tee joint is simple and reliable in structure, high in durability, convenient to machine and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, relates to a micro-irrigation system and its connecting tee, and in particular relates to a slider reversing jet tee and a pulse micro-irrigation system. Background technique [0002] Pulse micro-irrigation has the characteristics of strong anti-clogging performance and high irrigation uniformity, and has been widely concerned and applied by countries all over the world. The pulse generator is the core device that turns the pressure water flow in the micro-irrigation system into a pulse water flow. The existing pulse generator generally generates a pulse water flow through an electronic pulse device, a pulse solenoid valve, or elastic materials such as rubber, plastic film, and spring, and the cost is high. , The installation, use and maintenance are relatively complicated and easy to be damaged by fatigue. In the pulsed micro-irrigation system with frequency convers...
