A kind of nitrogen that this utility model provides fills into instrument wind controlling and regulating system, controlling and regulating system and instrument automatically
Wind air feed pipeline A connects, and in this specific embodiment, regulating system includes a nitrogen pipeline C, wind side pipe line B, DCS are remote for instrument
Pass control system (DIstributed Control System) (not shown), pressure regulator 13, check (non-return) valve 6, instrument wind side
Cut valve 7, valve 8, automatic control and adjustment valve group, by-pass valve group are cut in nitrogen side；Instrument wind air feed pipeline A outside device selects close
Branch line is drawn in the position (after for example instrument wind sends main valve 9 outside) of reason orders as instrument wind side pipe line B, a be instrument distinguished and admirable to direction.
In this preferred embodiment, instrument wind side pipe line B is connected with pressure regulator 13, automatically adjusts valve group, instrument wind
Valve 7 is cut in side, valve 8 is cut in nitrogen side, and instrument wind side pipe line B is connected with nitrogen pipeline C, and pressure regulator 13 and a DCS teletransmission control
System connects, and the pressure signal that pressure regulator produces introduces control room DCS system.
Automatically adjust valve group in this preferred embodiment and be arranged at that valve 7 is cut in instrument wind side, nitrogen side is cut between valve 8, automatically adjust
When section valve group can realize instrument wind system pressure anomaly, (instrument wind system pressure anomaly refers to the air-supply of pressure regulator detection
Pressure P is less than preset pressure), nitrogen can in time, quickly fill into instrument wind system, maintains stablizing of instrument wind system pressure,
Ensure the stable operation producing, automatically adjust valve group and further include：Nitrogen side quick-break valve 3, regulating valve 2, the side quick-break of instrument wind
Valve 1, nitrogen side quick-break valve 3, regulating valve 2, instrument wind side quick-break valve 1 flow to direction b along nitrogen and are sequentially connected with, the quick-break of nitrogen side
Draw emptying valve group between valve 3 and regulating valve 2, set up this emptying valve group in this place, its effect is (so-called just to realize normal condition
Often state refers to, and the blast pressure P of pressure regulator reaches preset pressure) under, keep normal pressure between valve group, it is to avoid in each valve
Leakage, nitrogen is mutually altered with instrument wind.Emptying valve group further includes that emptying cuts valve 5, emptying quick-break valve 4, and emptying quick-break valve 4 passes through to put
The empty valve 5 that cuts is connected with instrument wind side pipe line B.
In this preferred embodiment, set up by-pass valve group, this by-pass valve group is connected in parallel with automatically adjusting valve group, for when certainly
During dynamic control valve group fault, fill into nitrogen by adjusting by-pass valve group to instrument wind system, maintain the normal of instrument drive source of the gas
Supply；By-pass valve group further includes a nitrogen side bypass valve 11, an instrument wind side bypass valve 10, nitrogen side bypass valve 11, instrument
