Embodiment

[0020] Embodiment: A water inlet main valve for a hydropower station, its structural schematic diagram is as follows figure 1 As shown, it includes a controller 1, a vacuum valve 2, a vacuum breaking valve 3 and a water diversion pipe 4. The main body of the water diversion pipe is arched, and the height of the water inlet 5 of the water diversion pipe is higher than that of the water outlet 6 of the water diversion pipe. A vacuum valve and a vacuum breaker valve are arranged on the bow-shaped top, and the vacuum valve and the vacuum breaker valve are connected to the controller at the same time. The gradient from the water inlet of the water diversion pipe to the arched top is smaller than the gradient from the water outlet of the water diversion pipe to the arched top. The section width of the water inlet is larger than that of the water outlet, and the section width of the water outlet is consistent with the section width of the subsequent water diversion pipe.

Abstract

The invention discloses a water inlet main valve for a hydropower station and an operation method thereof. The water inlet main valve comprises a controller, a vacuum valve, a vacuum breaking valve and a water diversion pipe. The water inlet main valve is characterized in that a body of the water diversion pipe is in an arch back shape, the height of a water inlet of the water diversion pipe is larger than the height of a water outlet of the water diversion pipe, the top of the arch back shape is provided with the vacuum valve and the vacuum breaking valve, and the vacuum valve and the vacuum breaking valve are connected with the controller at the same time. By means of the water inlet main valve for the hydropower station and the operation method thereof, an upstream water source can be opened or cut off effectively, water leakage cannot be generated after the water source is cut off for a long time, potential safety hazards are avoided, and meanwhile, the water inlet main valve is convenient to maintain and replace.

Description

technical field [0001] The invention relates to the technical field of hydropower stations, in particular to a water inlet main valve for a hydropower station and an operating method thereof. Background technique [0002] At present, conventional gate valves, butterfly valves, and ball valves are used as the main valves of the water inlets of hydropower stations. There is a common problem: with the prolongation of operation time, the amount of water leakage will become larger and larger, which is difficult to repair. There is a lot of trouble and safety hazard. Chinese Patent Publication No. CN103603837A, published on February 26, 2014, the invention patent titled "hydraulic power station water inlet fast gate hydraulic control system" discloses a hydropower station water inlet fast gate hydraulic control system, including the first water inlet fast gate control panel, the second water inlet quick gate control panel and the water inlet quick gate control shared screen; the ...
