Cov lus qhia kev txhim kho rau flanged pob li qub Kev cai rau kev teeb tsa thiab siv cov roj liquefied li qub

Cov lus qhia kev txhim kho rau flanged pob li qub Kev cai rau kev teeb tsa thiab kev siv cov roj liquefied li qub 1. Lub perpendicularity ntawm flange nto ntawm cov yeeb nkab thiab cov kab nruab nrab ntawm cov yeeb nkab thiab qhov yuam kev ntawm flange bolt qhov yuav tsum nyob rau hauv qhov ntau ntawm cov kev tso cai. tus nqi. Valve thiab piping center kab yuav tsum zoo ib yam ua ntej installation. 2. Thaum fastening bolts, siv ib tug ciaj ntswj uas phim cov txiv ntseej. Thaum siv cov roj siab thiab cov cuab yeej pneumatic rau fastening, ua tib zoo mloog kom tsis txhob dhau lub zog torque. 3. Thaum txuas ob lub flanges, ua ntej ntawm tag nrho cov, lub flange sealing nto thiab gasket yuav tsum tau nias tusyees, thiaj li yuav xyuas kom meej tias lub flange txuas nrog tib lub bolt kev nyuaj siab. 4. Lub fastening ntawm lub flange yuav tsum tsis txhob sib sib zog nqus quab yuam, thiab yuav tsum tau nruj nruj raws li cov kev taw qhia ntawm symmetry thiab kev sib tshuam. 5. Tom qab flange installation, xyuas kom meej tias tag nrho cov bolts thiab ceev yog fastened tusyees. 6, lub fastening ntawm bolts thiab txiv ntseej, thiaj li yuav tiv thaiv kom txhob loosening los ntawm kev co, siv washers. Txhawm rau kom tsis txhob muaj adhesion ntawm cov xov ntawm qhov kub siab, cov xov xov yuav tsum tau coated nrog tus neeg sawv cev los tiv thaiv adhesion thaum lub sijhawm teeb tsa. 7. Nws yog siv rau qhov kub thiab txias li qub tshaj 300 ℃. Tom qab qhov kub thiab txias, lub flange kev twb kev txuas bolts, valve npog fastening bolts, siab seals thiab packing gland bolts yuav tsum tau nruj dua. 8, tsis tshua muaj kub valve yog ntsia rau hauv lub xeev ntawm atmospheric kub, vim qhov tsim ntawm qhov sib txawv ntawm qhov kub thiab txias, flange, gasket, bolts thiab txiv ntseej shrink, thiab vim hais tias cov khoom ntawm cov khoom no tsis zoo ib yam 9, cov kev nthuav dav coefficient yog. kuj sib txawv, tsim ib qho yooj yim heev rau xau ib puag ncig tej yam kev mob. Los ntawm qhov teeb meem no lub hom phiaj, thaum nruj bolts ntawm atmospheric kub, lub torque uas yuav siv sij hawm mus rau hauv tus account lub contraction yam ntawm txhua yam ntawm qhov kub thiab txias yuav tsum tau saws. 1. Ua ntej kev teeb tsa, cov kab noj hniav sab hauv ntawm LPG valve yuav tsum tau muab ntxuav thiab qhov tsis xws luag hauv kev thauj mus los yuav tsum raug tshem tawm; 2. Lub installation ntawm LPG valve yuav tsum ua kom tus npauj npaim valve tsav ncej kab rov tav thiab lub piston valve vertically upward; 3. Ua ntej siv lub LPG valve, cov khoom siv kis tau tus mob yuav tsum tau hloov kho kom lub zog ntawm cov khoom sib kis tsis zoo, thiab kev txwv tsis pub muaj zog thiab kev tiv thaiv kev tiv thaiv ntau dhau yog txhim khu kev qha; 4. Lubricating roj yuav tsum tau ntxiv tag nrho ua ntej commissioning thiab siv ntawm txhua lubricating ib feem ntawm lub LPG valve kis tau tus mob ntaus ntawv; 5. Ua ntej pib lub tshuab hluav taws xob, phau ntawv qhia ntawm lub tshuab hluav taws xob ntawm cov roj liquefied valve yuav tsum tau ua tib zoo nyeem.
