Description

Technical field

[0001] The present invention relates to the field of water conservancy engineering, and more particularly to a pressure regulating chamber device for hydropower stations.Background technique

[0002] The pressure regulating chamber structure is a pressure regulating regulator, which is commonly used in hydropower stations. Since the hydropower station is long, once the unit emergency stop or suddenly reduces the opening degree, it is easy to generate a certain water shock pressure in the pressure pipe, and the hydrotential pressure exceeds the hydropower station pressure. When the pipe is allowed to stress, it will cause damage to the pressure pipeline, causing safety hazards.

[0003] When the pressure of the hydropower pipe pressure pipeline is controlled, there is a multi-use extension unit to turn off the start and stop, and increase the strength of pressure pipeline, the pressure regulating room structure is an important engineering measures that effectively reduce the pr...
