Embodiment Construction

[0014] Now in conjunction with the accompanying drawings the specific embodiment of the present invention is further described as follows:

[0015] From figure 1 and figure 2 It can be seen that the present invention is a water volume control valve, mainly comprising: 1, 2, 3 discharge ports, 4 discharge ports, 5 irrigation water pipes, 6 discharge wells, 7, 8 water levels. Water levels 7 and 8 in the figure share the same characteristics of agricultural water conservancy projects such as rural reservoirs and fish ponds, so no further description is given. 1, 2, and 3 discharge outlets are plastic pipe fittings, which are poured into the step-like concrete platform from top to bottom in the 6 discharge well, connected with the 5 irrigation water pipe, and the 4 discharge outlets at the bottom of the 6 discharge well and the bottom of the water conservancy projects such as reservoir fish ponds In the same way, the 5 discharge well is a concrete structure, which is built belo...

Abstract

The invention relates to a water flow control valve which is a mating device used for irrigation drainage of agricultural small hydraulic power projects such as a village reservoir fish pond. Drainage openings with different heights are formed in a drainage well, one of the drainage openings is selectively opened, and the drainage water quantity of the reservoir fish pond is controlled through the height of the position where the opened drainage opening is formed. The problems that when irrigation drainage is carried out during original agricultural production, the drainage water quantity is watched and controlled completely depending on manual work, time, labor and spirit are wasted, and waste of water power resources is prone to being caused are solved.

Description

[0001] The water volume control valve involved in the present invention is a supporting device used for discharging irrigation water in agricultural small water conservancy projects such as rural reservoirs and fish ponds. The height of the discharge outlet is used to control the water discharge of the fish pond in the reservoir. Background technique [0002] At present, some water areas such as reservoirs and fish ponds in rural areas of our country are irrigated and released, and the water discharge valve is opened according to the amount of water required for farmland irrigation, and personnel are used to wait and observe. This operation is time-consuming and labor-intensive, and it is easy to cause waste and discharge a large amount of water. Through the combination of theoretical and technical research and practical experience, research and development have been developed according to the needs of agricultural production. By constructing drainage wells beside the dams of ...
