Pressure regulating chamber device for hydropower station

Abstract

The invention provides a pressure regulating chamber device for a hydropower station. By arranging a left supporting rod and a right supporting rod, the stress performance of a pressure regulating chamber is improved; by arranging a left branch pipe and a right branch pipe, effective buffering of the pressure regulating chamber structure and a pressure pipeline is achieved, and the water hammer pressure is reduced; and protruding sections are arranged in the left branch pipe and the right branch pipe, a plurality of vertical plates are arranged in the left branch pipe and the right branch pipe correspondingly, effective buffering of the water hammer pressure is achieved, and the pressure regulating and stabilizing performance of the pressure regulating chamber is further improved. The structure is simple, construction is easy, and the working performance of the pressure regulating chamber can be remarkably improved.

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...

Problems solved by technology

[0002] The surge chamber structure is a commonly used pressure regulating and stabilizing device in hydropower stations. Due to the long pressure pipes of hydropower stations, once the unit shuts down in an emergency or suddenly reduces the opening, it is easy to generate a certain amount of water hammer pressure in the pressure pipes, and the water hammer pressure exceeds the pressure of the hydropower station. When the pipeline is allowed to stress, it will cause damage to the pressure pipeline and cause safety hazards

[0003] When controlling the water hammer pressure of the pressure pipeline of the hydropower station, it is often used to prolong the shutdown start-stop time of the unit, and to increase the strength of the pressure pipeline, etc. The structure of the surge chamber is an important engineering measure to effectively reduce the water hammer pressure. The pipe is connected to the pressure pipe, its energy dissipation effect is average, the water hammer pressure cannot be consumed in time, and the large water hammer pressure will still affect the structural safety
