Problems solved by technology

[0002] The existing water turbine inlet valve control system in China still adopts the structure of the air-supplementing oil pressure device. For decades, the cast stop valve has been used as the control element in the control system, and all of them are connected by steel pipelines. Therefore, the control The layout of the components is relatively scattered, resulting in a large volume of the control device, inconvenient operation,

Abstract

The invention relates to a high-voltage energy-storage hydraulic work device, comprising a hydraulic source supply pipe formed by connecting a scavenge delivery and an accumulator output pipe in parallel, characterized in that: 1,2-position four-way reversal valve A of one path of the hydraulic source supply pipe controls a first operating cylinder D to realize the drive control of a butterfly valve start-stop and 2,3-position four-way reversal valve B of another path controls a second operating cylinder B to realize the pull-out and insert of the butterfly valve lock ingot, the third path controls a third operating cylinder F to realize the drive of a by-pass valve start-stop by a 3,2-position four-way reversal valve. The work device provides stable pressure oil source for the inlet valve hydraulic actuator of hydraulic turbine generator unit, with features of high reliability, compactness and convenient operation; and the system can normally work when the oil pump can not in normal working.

Description

technical field [0001] The invention relates to a high-pressure energy storage hydraulic working device. technical background [0002] The existing water turbine inlet valve control system still adopts the structure of the supplementary air hydraulic device in China. For decades, the cast globe valve has been used as the control element in the control system, and all of them are connected by steel pipelines. The arrangement of components is relatively scattered, resulting in a bulky control device, inconvenient operation, and unfavorable realization of automatic control. In addition, the cast globe valve itself is relatively rough and has poor sealing performance, and the connected pipeline is long and has many pipe joints, so it is prone to leakage, which reduces the reliability of the control device, and even causes misoperation and refusal to operate, which endangers the turbine equipment. safety, leading to the occurrence of power plant accidents.
