隔膜阀和油压之间的关系

隔膜阀和油压之间的关系

原文: 隔膜阀的工作温度通常受隔膜和阀体衬里所使用材料的限制,它的工作温度范围大约为-50~175℃。隔膜阀结构简单,只由阀体、膜片和阀头组合件三个主要部件构成。该阀易于快速拆卸和维修,更换隔膜可以在现场及短时间内完成。隔膜阀是连接润滑油和EH油的唯一环节,隔膜阀上部是机械超速和手动遮断油母管,机组挂闸前启动高压备用密封油泵,由高密泵提供油压将隔膜阀关闭。主油泵工作正常后由主油泵出口提供油压,机组运行中隔膜阀始终关闭。机械超速保护保护动作或就地打闸时首先泄掉隔膜阀上部机械超速和手动遮断油母管油压,隔膜阀开启,泄油口打开,进而泄去AST油压(安全油压),主汽门、调速汽门关闭停机。 隔膜阀和油压之间的关系。

译文: Diaphragm valve working temperature is usually limited by the diaphragm and body lining material used, its working temperature range is about – 50 ~ 175 ℃. Diaphragm valve has simple structure, only by the body, diaphragm and valve head assembly of three main parts. The valve is easy to be fast disassembly and maintenance, replacement diaphragm can be done in the field and in a short period of time. Diaphragm valve is the only link connection and EH oil lubricating oil, the upper diaphragm valve is a mechanical overspeed and manual interrupt oil pipe, before hanging brake unit start-up spare seal oil pump high pressure, the density will provide hydraulic diaphragm pump valve is closed. The main oil pump is provided by the main oil pump export oil pressure after work, in the operation of the unit the diaphragm valve is closed. Mechanical overspeed protection protection action or in the gate first drain off the upper diaphragm valve mechanical overspeed and manual interrupt mother tube hydraulic oil, diaphragm valve open, drainage mouth open, and then discharge to AST oil-pressure (safety hydraulic), the main valve, control valve to close down.隔膜阀和油压之间的关系。
