Problems solved by technology

[0002] Most of the existing paddy field irrigation valves use floats as the power to open and close the valve. The disadvantage is that when the water level is close to the predetermined value, the water flow will be greatly reduced, and the valve closing speed is slow and cannot be completely closed, which cannot meet the needs of larg

Abstract

The invention provides a large flow mechanical self-controlling valve for irrigating paddy fields, belonging to the field of a water level control valve and aiming to solve the technical problems that the valve can be automatically opened and closed by using the water level difference in front and back of a dam under a large flow state. In order to solve the technical problems, the large flow mechanical self-controlling valve for irrigating paddy fields comprises a valve body, a butterfly valve plate, a floater and impellers; the valve is characterized in that the butterfly valve plate, a steering device, the directed floater and a diversion pipe are arranged in the valve body; an interception plate is arranged in the diversion pipe; and the impellers are arranged at the outlet of the diversion pipe. As the butterfly valve plate is adopted in the invention, the pressure difference in front and back of the valve plate is not required to be overcome during opening and closing; and moreover, the impellers with strong output power are used as a power output device of the valve plate, thus, the valve plate can be opened and closed fast under the large flow state.

Description

technical field [0001] The invention relates to a water level control valve, in particular to a large-flow mechanical automatic control valve for paddy field irrigation. Background technique [0002] Most of the existing paddy field irrigation valves use floats as the power to open and close the valve. The disadvantage is that when the water level is close to the predetermined value, the water flow will be greatly reduced, and the valve closing speed is slow and cannot be completely closed, which cannot meet the needs of large flow in the paddy field irrigation process. The technical characteristics and water volume requirements of realizing the instant opening and closing of the valve under the state. Although this problem can be solved if the motor is installed on the valve, it does not meet the actual situation that the current rural power facilities are not perfect. Contents of the invention [0003] Aiming at the problems mentioned in the background technology, the t...
