Problems solved by technology

The disadvantages of this structure are: 1, because it is difficult to seal between the gate plate and the gate groove, the water channel often leaks
2. It is easy to get stuck due to the shape or deformation, and it is difficult to lift and release the gate due to manual operation; 3. This kind of gate is not easy to control the water volume, resulting in a lot of waste of water.
4. It is not easy to manage especially when the social atmosphere is bad, and it is easy to be artificially lifted to steal water or destroy or steal the gate board
5. A large number of water discharge valves for canals are temporarily installed before irrigation, and need to be dismantled after irrigation, resulting in waste of manpower and material resources

Abstract

The invention relates to canal drainage facilities with a valve plate type pneumatic valve. The canal drainage facilities with the valve plate type pneumatic valve are characterized in that a manhole is arranged at a junction between a main canal and a branch canal, the valve plate type pneumatic valve is installed in the manhole, the valve plate type pneumatic valve enables the main canal to be communicated with the branch canal, a cover is arranged at the mouth of the manhole, and the mouth of the manhole and the cover are mutually and tightly locked through a lock; when irrigation is needed, a front chamber of an air cylinder is inflated through an inflating nozzle by using an inflator, and a valve plate is opened to supply water; when irrigation is stopped, a rear chamber of the air cylinder is inflated, the valve plate is closed to stop water supply, the valve plate tightly presses a valve port under the effect of water pressure, and water leakage is prevented. The canal drainage facilities with the valve plate type pneumatic valve has the advantages that the opening and closing operation is easy, no water leaks at all, the water quantity is kept constant, the situation that people secretly drain water is avoided, etc.

Description

technical field [0001] The present invention relates to a canal water discharge facility. Background technique [0002] At present, reservoirs often supply water to irrigation users regularly and quantitatively through canal discharge valves. In the existing drainage facilities, concrete pipes are set at the bottom of the canal wing walls, and concrete gate grooves are set at the nozzles of the concrete pipes, and the gate plates are inserted into the gate grooves. The gate plate is made of wood or concrete. The shortcomings of this structure are: 1. Because it is difficult to seal between the gate plate and the gate, the water channel often leaks. 2. Due to the shape structure or deformation, it is easy to get stuck, and because of manual operation, it is difficult to lift and release the gate; 3. This kind of gate is not easy to control the size of the water, resulting in a lot of waste of water. 4. It is inconvenient to manage especially in the case of bad social atmos...
