Problems solved by technology

Now there is a technology that puts the water storage container directly into the ground, and controls the amount of water seepage in the container to achieve long-term water supply. The disadvantage of this method is that the water supply cannot be adjusted according to the water content (moisture) of the soil, resulting in It is a big waste; and the water storage container must be taken out after use, resulting in a waste of human resources, otherwise it will pollute the environment
In addition, in gardening and agricultural production, the valves of the water supply system are generally controlled manually or electronically, resulting in a waste of personnel and energy.
At the same time, there is also the disadvantage that the water supply cannot be automatically adjusted according to the water content of the soil.

Embodiment Construction

[0018] The specific embodiment of the intelligent water-saving valve of the present invention is as follows: figure 1 Shown is composed of valve body 1, valve core 2 and control device, valve body 1 is provided with water inlet 3 and water outlet 4; the control device is composed of expansion body 5 and reset device, valve core 2, expansion body 5 Both the reset device and the reset device are located in the valve body 1; the expansion body 5 expands after absorbing water and pushes the valve core 2 to close the valve, and the expansion body 5 shrinks after losing water, and the reset device pushes the valve core 2 to reset and open the valve.

[0019] The reset device is composed of a return spring 6, a plunger 7 and a main spring 8. The return spring 6 is set on the valve core 2, and the two ends act on the valve body 1 and the valve core 2 respectively. The plunger 7 and the main spring 8 The two ends of the main spring 8 act on the plunger 7 and the valve core 2 respective...

Abstract

An intelligent valve of water ¿C saving type is prepared as setting water inlet and water outlet on valve body; forming control unit by expansion body reset component; setting spool, expansion body and reset component in valve body; pushing spool to close valve by expansion body when expansion body is expanded by absorbing water and pushing spool to be reset for opening valve by reset component when expansion body is contracted by losing water; using regulation unit on valve body to regulate volume of expansion body to let valve open or close according to water content in soil.

Description

technical field [0001] The invention relates to a device method for supplying water to plants in the field of forestry and agriculture, in particular to an intelligent control valve according to the water content of irrigated soil. Background technique [0002] With the development of society and the advancement of science and technology, people's ability to conquer and transform nature is gradually improving. In the process of conquering and transforming nature, people have caused great damage to the natural environment. Now people have realized this serious problem, and afforestation is the best method in the process of treating barren mountains and deserts, but how to provide sufficient water sources for plants in the process of planting trees in these areas has not been well solved for a long time. The problem is that this causes tree planting to be done every year, that is, there is no forest. Also there is above-mentioned problem in gardening and agricultural product...
