Irrigation water conveying pipe flow induction regulating valve

Abstract

The invention relates to an irrigation water conveying pipe flow induction regulating valve. The irrigation water conveying pipe flow induction regulating valve comprises a valve deck, a rubber film, a spring, a valve rod, a valve block, an upper valve body, a lower valve body and an induction mechanism; the upper valve body comprises a water storage cavity and a valve body connection part; a valve body connection head is arranged on the water storage cavity; a valve rod cavity is formed in the valve body connection part; a valve block sealing mechanism corresponding to the valve block is arranged in the lower valve body; the valve block is arranged in the lower valve body; the rubber film, the spring, the valve rod and the valve block are installed together; and in the initial state of the spring, the lower valve body is sealed by the valve block, the valve deck and the upper valve body are installed together, the rubber film is fixed, the upper valve body and the lower valve body are installed together, and the induction mechanism is connected with the valve body connection head. The irrigation water conveying pipe flow induction regulating valve can achieve efficient and accurate irrigation effect, achieves the purposes of water saving, energy saving, labor saving, consumption reducing and the like, and can promote fast and sustainable development of modern agriculture easily.

Description

technical field [0001] The invention relates to a flow sensing regulating valve of an irrigation water delivery pipe, which belongs to the field of water-saving irrigation. Background technique [0002] Drip irrigation is the most efficient water use and advanced precision irrigation technology in agricultural water-saving projects. Its system structure is mainly composed of the head, water pipeline, control valve and sprinkler. At present, the work of the drip irrigation system is mainly based on the design and division of the wheel irrigation area of ​​the irrigation plot, and the opening and opening and closing status of the valves on the pipe network are automatically controlled by manual or programmed controllers, so as to control the water delivery of the irrigation pipe network in real time. state, the amount of irrigation water, and effectively complete the mutual switching of each wheel irrigation area in the state of "start irrigation / stop irrigation". Authorized ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a flow sensing regulating valve for irrigation water pipes, which solves the problem that the existing drip irrigation device is only a "planned passive" water delivery irrigation mode, and cannot "actively adjust" the supply flow of the water pipe according to the actual drought situation of the plot to be irrigated. , thereby affecting the water-saving irrigation effect of achieving appropriate water supply, high-efficiency water use, precise irrigation, saving energy consumption, and improving the level of automation, and the existing automatic drip tank device uses water-absorbing rubber as a power source, resulting in a lag in irrigation response. Timely response to moisture, timely irrigation and other issues
