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.…… .
