Multilayer ebb-and-flow system based on mechanical one-way adjustable valve

Abstract

A multilayer ebb-and-flow system based on a mechanical one-way adjustable valve comprises a multilayer cultivation frame, a liquid storage tank, a controller, a water pump, the mechanical one-way adjustable valve, a liquid feeding and discharging integrated pipeline and an overflow pipe, wherein the water pump arranged in the liquid storage tank, the mechanical one-way adjustable valve, the liquidfeeding and discharging integrated pipeline, the multilayer cultivation frame, the overflow pipe and the liquid storage tank are sequentially connected to form a loop. Liquid feeding and liquid discharging share one pipeline system, the multilayer ebb-and-flow system is simple in structure, liquid feeding and discharging flow can be regulated only by one mechanical one-way adjustable valve without an electronic circuit and a plurality of solenoid valves, the manufacturing cost of the system is greatly reduced, and a system operating mechanism is simplified.

Description

technical field [0001] The invention relates to a technology in the field of plant planting, in particular to a multi-layer tidal irrigation system based on a mechanical one-way adjustable valve. Background technique [0002] At present, tidal irrigation, as a new water and fertilizer supply method for industrialized plant cultivation schemes, has the advantages of thorough irrigation, uniform water and fertilizer, and simple structure. This protocol has long been widely used in monolayer plant culture. However, in the scenario of multi-layer plant cultivation, there is a pressure difference between the liquid supply and discharge of each layer due to the difference in layer height. After the uniform flow of each layer, it is often impossible to change the diameter again when draining the liquid, resulting in slow drainage of the bottom cultivation tank or even backfilling. If the solution of two sets of pipelines for liquid supply and drainage is adopted, multiple sets of ...

Problems solved by technology

[0003] Aiming at the defects of complex structure and high cost of the multi-electromagnetic valve scheme commonly used in the existing multi-layer tidal irrigation scheme, the present invention proposes a multi-layer tidal irrigation system based on mechanical one-way adjustable valves. The liquid shares a pipeline system, which has a simple structure and does not rely on electronic circuits and multiple solenoid valves for regulation. Only one mechanical one-way adjustable valve is needed to complete the regulation of inflow and discharge and liquid flow, which greatly reduces the manufacturing cost of the system and simplifies the System Operation Mechanism
