自控仪表回路编号原则

自控仪表专业回路编号系统(process instrument loop number system)一 控制阀的位号区分开关阀及调节阀。开关阀：HV- loop tag No.调节阀：LCV- loop tag No.，FCV- loop tag No.，QCV- loop tag No.，HCV- loop tag No.The control valve is marked as follow: On/off valve: HV- loop tag No.Control valve: LCV- loop tag No., FCV- loop tag No., QCV- loop tag No., HCV- loop tag No.表1.仪表辨认功能代码 TABLE 1.
