This safety valve 7 is arranged on corresponding output pipe, and can prevent reducer pressure from climbing and bring danger to decompressor and downstream pipe and equipment use, be can releasing pressure automatically when downstream pressure exceedes setting pressure.
Discharge in control panel is also taken over road 6 and is discharged and take over road 8, purges respectively as safety valve floss hole and left side the outlet connecting pipe road that control valve and right side purge control valve.
The band formed according to such scheme discharge and to connect and uninterruptedly the gas control panel of air feed, when carrying out work, is connected two gas cylinders respectively by suction port A with B on it, sets corresponding pressure relief value by the setting decompressor 2 in left side.
Left gas enters from suction port A, left side decompressor (namely setting decompressor) 2 is entered through left side air inlet switch control valve 11, left side high-pressure manometer 21 on decompressor shows left side air inlet pressure force value, left side low pressure gauge 22 shows left side outlet pressure value, enters the left side leaving air control valve 31 in leaving air control valve group 3 by decompressor after being reduced pressure.
Top right gas enters from suction port B, right side decompressor (namely switching decompressor 4) is entered through right side air inlet switch control valve 51, right side high-pressure manometer 41 on decompressor 4 shows right side air inlet pressure force value, right side low pressure gauge 42 shows right side outlet pressure value, enters the right side leaving air control valve 32 in leaving air control valve group 3 by decompressor after being reduced pressure.
The each valve of leaving air control valve group 3 is all in opening state, when right side decompressor (namely switch decompressor 4) finger to the left time, left side decompressor delivery pressure higher than right side decompressor, by left side air feed; When left side is along with cylinder gas pressure drop, when left side decompressor delivery pressure is lower than right side decompressor delivery pressure, system automatically switches to right side air feed, to ensure the constant air feed in downstream.
Because the outlet (i.e. the outlet of main line leaving air control valve 33) of leaving air control valve group 3 is connected with the import of safety valve 7, after gas enters safety valve, exported C to downstream air feed from safety valve 7.Because two, the left and right joint of safety valve is all as the floss hole for safety valve, left side floss hole is connected with the outlet that left side purges control valve 12 through discharging and taking over road 6, right-side outlet through discharging and taking over road 8, then is connected with the outlet of right side floss hole by a tee union.When toxic and harmful decompression is used, because decompressor Long-Time Service or gas reason cause decompressor to occur, pressure climbs, and when pressure is increased to the setting pressure of safety valve, safety valve is opened automatically, gas is discharged by purging floss hole D or is reclaimed, to guarantee down-stream system safety.
Simultaneously, floss hole due to safety valve is distributed in the left and right sides of safety valve, and the blow valve port of floss hole and the left and right sides is at grade, thus can realize safety relief pipeline, purge discharge pipe effectively gather together make system pipeline connect more succinct, easy for installation.
For when using when air feed can not be interrupted, when decompressor Long-Time Service or gas reason cause one-sided decompressor to break down, need to keep in repair time, leaving air control valve group 3 can be closed and correspond to this side leaving air control valve, remove gas cylinder part, this side decompressor air feed module is pulled down and keeps in repair, and opposite side decompressor air feed module can work on, thus ensure downstream air feed incessantly.After fault decompressor air feed module maintenance completes, can Access Control panel again, can air feed use be carried out after purging.
