一、燃料气橇简介在西气东输二线(西段)各压气站场中,燃料气橇的调压部分均采用RMG512调压阀。其压力控制系统由一台安全切断阀和两台调压阀(监控调压阀、工作调压阀)串联在一起组成,即监控调压方式。安全切断阀、监控调压阀、工作调压阀为相互独立的设备。正常情况下,安全切断阀和监控调压阀处于全开位置,由工作调压阀对下游压力进行控制。当工作调压阀出现故障(处于全开位置)无法控制下游压力时,监控调压阀
First, the fuel gas skid Brief introduction In the second West-East Gas Pipeline (West Section) of the gas stations, fuel gas sled regulator are used RMG512 regulator. The pressure control system consists of a safety shut-off valve and two pressure regulating valve (monitoring pressure regulating valve, working pressure regulating valve) in series together, that is, monitoring the pressure regulator. Safety shut-off valve, monitoring pressure regulator, pressure regulator for the work of independent equipment. Under normal circumstances, the safety cut-off valve and monitoring pressure regulator in a fully open position, the work of the pressure regulating valve on the downstream pressure control. When the work pressure regulator fails (in the fully open position) can not control the downstream pressure, the monitoring pressure regulator
