Abstract

The invention relates to the technical field of valves, and discloses a valve for automatic flow control, comprising: a main pipeline, one end of which is connected to a water pump, the other end of which is connected to a drainage area, and the main pipeline is provided with a first valve and a second valve. Two valves, the first valve is set at the end of the main pipeline close to the water pump, the second valve is set at the end of the main pipeline close to the drainage area; branch pipelines, the number of branch pipelines is multiple, and one end of the branch pipelines is connected to the main pipeline, The other end of the branch pipe is connected to the farmland; a third valve is provided on the branch pipe; when irrigation is required, the second valve is closed, the first valve is opened, and then the third valve is opened to realize irrigation; The three valves are closed, and then the first valve is closed; when the third valve is closed, the first valve and the second valve are opened to realize cleaning of the main pipeline. The valve for automatically controlling flow provided by the technical solution of the invention can realize precise irrigation of water and fertilizer.

Description

technical field [0001] The patent of the present invention relates to the technical field of valves, in particular, to a valve for automatic flow control. Background technique [0002] In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. And with the rapid development of science and technology, many places have begun to implement automated water and fertilizer irrigation in order to reduce manpower. [0003] In the process of automatic water and fertilizer irrigation, in order to realize automatic irrigation, it is generally necessary to control the power source to open the control valve, and then spray water and fertilizer to realize water and fertilizer irrigati...
