Abstract

The invention relates to the technical field of valves and discloses an automatic flow control valve. The automatic flow control valve comprises a main pipeline and a plurality of branch pipelines, wherein one end of the main pipeline is connected to a water pump, and the other end of the main pipeline is connected to a drainage area; a first valve and a second valve are arranged on the main pipeline; the first valve is arranged at the end, close to the water pump, of the main pipeline; the second valve is arranged at the end, close to the drainage area, of the main pipeline; one end of each branch pipeline is connected to the main pipeline, and the other end of the branch pipeline is connected to a farmland; a third valve is arranged on each branch pipeline; when irrigation is needed, thesecond valve is closed, the first valve is opened, then the corresponding third valve is opened, and irrigation is achieved; when irrigation is stopped, the corresponding third valve is closed, and then the first valve is closed; and when the corresponding third valve is closed and the first valve and the second valve are opened, the main pipeline is cleaned. According to the automatic flow control valve in the technical scheme, precise irrigation of water and fertilizer can be realized.

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...
