Fluidic impulse tee joint

Abstract

The invention discloses a fluidic impulse tee joint. The fluidic impulse tee joint comprises an inlet section, a fluidic element and two outlet sections. When the tee joint is applied to a micro-irrigation system, the inlet section is connected with a branch pipe, the fluidic element is located between the inlet section and the outlet sections, the two outlet sections are respectively connected with hair pipes, water flow passes through the inlet section from the branch pipe and enters into the fluidic element, the fluidic element generates impulse water flow, the water flow flows alternately in the two hair pipes intermittently according to a certain frequency, impulse water flow is formed in the hair pipes, the impulse water flow in the hair pipes enters an watering device, intense turbulent fluctuation and impact water flow is formed in the watering device, and the anti-blocking performance and the watering uniformity of the watering device are enhanced. The fluidic impulse tee joint has the advantages of being simple in structure and processing process, low in production cost and convenient to install and use. The fluidic impulse tee joint can be widely applied to irrigation requirements of field crops, vegetables, forest, fruits and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and relates to a capillary connection tee for a micro-irrigation system, in particular to a jet pulse tee. Background technique [0002] Pulse micro-irrigation has the characteristics of strong anti-clogging performance and high uniformity of irrigation, 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 pulse water flow through electronic pulse devices, pulse solenoid valves or elastic materials such as rubber, plastic films, and springs. The cost of electronic pulse devices, pulse solenoid valves and other devices is relatively high, and the installation, use, and maintenance are relatively complicated. They often require electronics-related professionals to oper...

AI Technical Summary

Problems solved by technology

The cost of electronic pulse devices, pulse solenoid valves and other devices is relatively high, and the installation, use, and maintenance are relatively complicated. They often require electronics-related professionals to operate and maintain them. However, most users of micro-irrigation systems are local farmers, who lack corresponding operations, Maintenance skills; micro-irrigation systems generally run for a long time, and elastic materials such as rubber, plastic films, and springs are prone to fatigue and even damage during long-term, high-frequency frequent reciprocating operations; the pulse frequency depends on the stiffness and initial The amount of compression, long-term operation will lead to changes in the stiffness and elastic modulus of the elastic material, the elasticity will decrease, and the sensitivity and reliability will decrease to varying degrees, which will affect the long-term operation and use of the pulse micro-irrigation system; the use of elastic materials will inevitably increase The complex structure of the pulse generator puts forward higher requirements for mechanical sealing, manufacturing precision, reliability and durability
