调压站启动锅炉天然气调压装置异常动作研究

Study on Abnormal State of Pressure Regulating Device of Start-up boiler in Natural Gas Pressure Regulating Station

本文主要阐述了调压站启动锅炉天然气调压装置快速切断阀异常频繁动作,针对快速切断阀频繁动作进行分析,得出是由于天然气热胀冷缩引起天然气压力波动,并对快速切断阀、二级调压阀进行参数调整,保障快速切断阀不再出现异常频繁动作。

This paper mainly describes the abnormal frequent action of the fast section valve in the pressure regulating device of the start-up boiler in the pressure regulating station.Based on the analysis of the frequent action of the fast section valve,it is concluded that the pressure fl uctuation of natural gas is caused by the expansion and contraction of natural gas,and the parameters of the fast section valve and the secondary pressure regulating valve are adjusted to ensure that the fast section valve does not act abnormally frequently.
