Iiflange zentsimbi yeCarbonzisetyenziswa ngokubanzi kwizicelo zemihla ngemihla, kunye nesixa esikhulu sokusetyenziswa kunye nokusetyenziswa ngokukhawuleza. Ngoko ke, ukugcinwa rhoqo kwee-carbon steel flanges kufuneka kube nemithetho ethile yokugcina umgangatho we-carbon steel flanges kangangoko kunokwenzeka kunye nokuphucula ukusebenza kakuhle. Mandabelane nawe ngemilinganiselo eyimfuneko yogcino lokusebenza oluzinzileyo lweyenziwe ngentsimbi eshayinayokunye ne-carbon steel flanges.
1. Ngaphambi kokusetyenziswa, coca umbhobho kunye nenxalenye ephuphumayo yomzimba wevalve ngamanzi acocekileyo ukuthintela iifayili zentsimbi ezishiyekileyo kunye nolunye udoti ekungeneni kumgodi ongaphakathi womzimba wevalvu.
2. Xa i-carbon steel flange ivaliwe, enye i-medium ihlala kumzimba wevalve kwaye ithwala uxinzelelo oluthile. Ngaphambi kokugqithisa i-carbon steel flange, vala ivalve yokuvala phambi kwe-carbon steel flange, vula i-carbon steel flange ukuze ihlaziywe, kwaye ukhulule ngokupheleleyo uxinzelelo lwangaphakathi lomzimba wevalve. Kwimeko ye-carbon steel flange yombane okanye i-valve yebhola ye-pneumatic, amandla kunye nokunikezelwa komoya kufuneka kunqanyulwe kuqala.
3. Ngokubanzi,PTFEisetyenziswa njengesixhobo sokutywina sokutywina okuthambileyo kwe-carbon steel flange, kunye nomphezulu wokutywina wevalve yebhola yokutywina yenziwe ngentsimbi engaphezulu. Ukuba kuyimfuneko ukucoca i-valve yebhola yombhobho, kufuneka kuthathelwe ingqalelo ukukhusela ukuvuza ngenxa yomonakalo kwindandatho yokutywina ngexesha lokuchithwa.
4. Xa udibanisa i-carbon steel flange, iibholiti kunye namantongomane kwi-flange kufuneka zilungiswe kuqala, kwaye ke zonke iinqununu kufuneka ziqiniswe kancane kwaye ziqiniswe ngokuqinileyo. Ukuba amandongomane amiswe ngenkani phambi kokuba kulungiswe amanye amandongomane, umphezulu we-gasket uya konakaliswa okanye uqhekeke ngenxa yomthwalo ongalinganiyo phakathi kobuso be-flange, okukhokelela ekuvuzeni okuphakathi kwi-valve flange butt joint.
5. Ukuba i-valve ihlanjululwe, i-solvent esetyenzisiweyo akufanele ingqubuzane kunye neendawo eziza kuhlanjululwa kwaye zingadli. Ukuba i-carbon steel flange ekhethekileyo yegesi, inokucocwa ngepetroli. Ezinye iindawo zinokucocwa ngamanzi abuyiselweyo. Ngexesha lokucoca, uthuli oluseleyo, ioli kunye nezinye iziqhotyoshelo ziya kucocwa ngokucokisekileyo. Ukuba abanako ukucocwa ngamanzi acocekileyo, banokucocwa ngotywala kunye nezinye izinto zokucoca ngaphandle kokulimaza umzimba we-valve kunye namalungu. Emva kokucoca, linda i-ejenti yokucoca ukuba iguqe ngokupheleleyo ngaphambi kokuhlanganisana.
6. Ukuba ukuvuza okuncinci kufunyenwe ekupakishweni ngexesha lokusetyenziswa, i-valve rod nut inokuqiniswa kancinane de kuyeke ukuvuza. Musa ukuqhubeka uqinisa.
Ukongeza, ukuba i-carbon steel flange ibekwe ngaphandle ixesha elide, ukuba akukho manyathelo angangeni manzi kunye nobungqina bokufuma, kuya kukhokelela ekudakaleni kweminye imizimba yevalve kunye namacandelo. Ukuze kuqinisekiswe ukuzinza kwe-carbon steel flange, uvavanyo kufuneka lwenziwe ngaphambi kokusetyenziswa.
