Lub installation ntawm kev ruaj ntseg valve yuav tsum ua raws li cov cai hauv qab no:
(l) Boilers nrog cov ntsuas evaporation muaj peev xwm ntau dua {{0}}}.5t / h yuav tsum tau nruab nrog tsawg kawg ob lub valve: Boilers nrog ntsuas evaporation muaj peev xwm tsawg dua lossis sib npaug li 0.5t / h yuav tsum tau nruab nrog tsawg kawg yog ib qho kev nyab xeeb valve. Kev nyab xeeb li qub yuav tsum tau muab tso rau ntawm qhov hluav taws xob ntawm lub tshuab hluav taws xob sib cais thiab lub qhov hluav taws xob ntawm chav superheater.
(2) Kev nyab xeeb valve yuav tsum tau muab ntsia rau hauv qhov chaw siab ntawm lub lauj kaub tub lag luam thiab lub taub hau. Nyob nruab nrab ntawm qhov kev nyab xeeb valve thiab lub lauj kaub los yog lub taub hau, yuav tsum tsis muaj qhov hluav taws xob cov yeeb nkab thiab lub valve rau kev noj chav.
(3) Lub pas nrig hom kev nyab xeeb yuav tsum muaj cov cuab yeej los tiv thaiv lub rauj txav los ntawm nws tus kheej thiab cov qauv qhia kom txwv lub zog ntawm kev hla dhau, thiab lub caij nplooj ntoos hlav-hom kev nyab xeeb valve yuav tsum muaj cov cuab yeej los nqa tus kov thiab tiv thaiv cov kho cov ntsia hlau los ntawm kev sib tw ntawm qhov xav tau.
(4) Rau boilers nrog ntsuas chav siab tsawg dua los yog sib npaug rau 3.82MPa, lub caj pas txoj kab uas hla ntawm qhov kev ruaj ntseg valve yuav tsum tsis txhob tsawg tshaj li 25 hli: rau boilers nrog ntsuas chav siab tshaj 3.82MPa, lub caj pas txoj kab uas hla ntawm lub valve kev ruaj ntseg yuav tsum. tsis tsawg tshaj 20mm.
(5) Qhov chaw hla ntu ntawm cov yeeb nkab txuas ntawm qhov kev nyab xeeb valve thiab lub boiler yuav tsum tsis txhob tsawg tshaj li qhov inlet cross-sectional cheeb tsam ntawm kev ruaj ntseg valve. Yog tias ob peb qhov kev nyab xeeb li qub tau teeb tsa ua ke ntawm cov yeeb nkab luv ncaj qha txuas nrog lub boiler, qhov chaw hla ntawm cov yeeb nkab luv yuav tsum tsis pub tsawg dua 1.25 npaug ntawm qhov chaw tso pa ntawm txhua qhov kev nyab xeeb li qub.
(6) Lub valve kev nyab xeeb feem ntau yuav tsum tau nruab nrog lub tshuab tso pa tawm, thiab cov yeeb nkab tso tawm yuav tsum tau txuas ncaj qha mus rau qhov chaw nyab xeeb thiab muaj qhov seem seem txaus los xyuas kom meej qhov ntws ntawm cov pa tawm. Hauv qab ntawm cov yeeb nkab ntawm qhov kev nyab xeeb valve yuav tsum tau nruab nrog lub cuab yeej txuas nrog rau qhov chaw nyab xeeb, thiab cov li qub tsis raug tso cai rau nruab rau ntawm cov yeeb nkab thiab cov ntxiab.
