Problems solved by technology

In the prior art, the measurement of product flow has always relied on professional institutions with sophisticated equipment, but the product needs to be measured repeatedly, the cycle is long and the measurement is expensive. Only one measurement costs nearly 1,000 yuan. For nearly 100 kinds of products every year Enterprises have a heavy burden and cannot master the core technology of their measurement

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , 2 As shown, a device for measuring the water flow of drip irrigation products includes a water injection valve 2, an air pressure regulating valve 3, a water pressure regulating valve 4, a PVC hose 5, and a pressure vessel barrel 1.

[0019] The upper end surface of the pressure vessel barrel 1 is respectively provided with threaded holes 1-1 for the water injection valve and 1-2 for the air pressure regulating valve. The lower end surface of the pressure vessel barrel 1 is provided with a pillar 1-3. On the body, handrails 1-4 are provided, on the barrel body at the lower end of the pressure vessel barrel 1, PVC hose threaded holes 1-5 and two shaft arms 1-6 are respectively provided, and two shaft arms 1-6 are provided with The shaft 1-7 is provided with wheels 1-8 at both ends of the shaft 1-7 respectively.

Abstract

The invention relates to a device and a using method for measuring the water flow of drip irrigation products. Connect the tap water pipe to the water injection valve, connect the air pressure adjustment valve to the air pump, and connect the drip irrigation belt to the PVC hose outlet; open the handle of the water injection valve, and close the water injection valve when the water volume is 3 / 4 of the volume of the pressure vessel barrel Handle; start the air pump, open the air pressure regulating valve handle to inject compressed air; open the water pressure regulating valve to pass water, immediately start timing with a stopwatch, then convert the flow rate per hour, and close the water pressure regulating valve, record the water in each measuring cup Whether the liters of water conform to the rated value of drip irrigation products, such as 1L, 2L, 3L, the range of liters generally fluctuates within 0.1L is a qualified product; in this way, the precise measurement of drip irrigation belt products can be realized in a simple and fast way. This technology only needs to invest in equipment once, without other additional costs, and saves nearly 200,000 yuan in product measurement costs a year.

Description

technical field [0001] The invention relates to a device for detecting agricultural irrigation products, in particular to a device for measuring water flow of drip irrigation products and a use method. Background technique [0002] Drip irrigation is one of the most water-saving irrigation technologies for farmland irrigation so far. According to the water requirements of crops, drip irrigation uses low-pressure piping systems and drippers installed on capillary tubes to transfer water and nutrients needed by crops evenly and slowly. Irrigation methods that drip into the soil in the root zone of crops. Drip irrigation does not destroy the soil structure, and the water, fertilizer, air, and heat inside the soil are always kept in a good condition suitable for crop growth, and the evaporation loss is small. It is a scientific and efficient irrigation method. Since the amount of water required by different crops is different, controlling the water flow of drip irrigation is th...
