Igama elisemthethweni lepleyiti eyimfama nguiflangeikepusi, enye ikwabizwa ngokuba yi-blind flange okanye iplagi yombhobho. Yiiflangengaphandle komngxuma phakathi, osetyenziselwa ukutywina umlomo wombhobho. UMSEBENZI UFANENE nentloko kunye ne-tube cap, ngaphandle kokuba isitywina esiyimfama sisixhobo sokutywina se-deTAChable, kwaye isitywina sentloko asilungele ukuvulwa kwakhona. Kukho iintlobo ezininzi zomphezulu wokutywina, kubandakanya inqwelomoya, umphezulu weconvex, umphezulu weconcave kunye neconvex, umphezulu we-tenon kunye nomphezulu wokudibanisa umsesane. Material: carbon steel, stainless steel, intsimbi yealloyi, ubhedu, ialuminium, iPVC kunye nePPR.
Ipleyiti eyimfama isetyenziselwa ukuhlukaniswa okupheleleyo kwendawo yokuvelisa ukukhusela imveliso ukuba ingachatshazelwa kukuvalwa kwe-valve yokunqunyulwa kunye nokubangela iingozi. Ipleyiti eyimfama kufuneka ibekwe kwiindawo ezifuna ukuba zodwa, ezifana nombhobho wesixhobo, ngaphambi nangemva kwevalve yokunqunyulwa okanye phakathi kweeflange ezimbini. Umzobo 8 ipleyiti eyimfama idla ngokucetyiswa. Ukucofa, ukucoca kunye nezinye iindawo zokusetyenziswa kwexesha elinye nazo zinokusebenzisa ipleyiti yeplagi (ipleyiti eyimfama ejikelezayo).

1. Kwinqanaba lokuqala lokulungiselela ukuqalisa, uvavanyo lwamandla okanye uvavanyo lokuqina lombhobho alunakwenziwa ngexesha elifanayo nezixhobo ezidibeneyo (ezifana ne-turbine, i-compressor, i-gasifier, i-reactor, njl.), kunye ne-blind blind. ipleyiti kufuneka imiselwe kuqhagamshelo phakathi kwesixhobo kunye nombhobho.
2. Kuzo zonke iintlobo zemibhobho yezinto zenkqubo eqhagamshelwe kwindawo yomda ngaphandle kwendawo yomda, xa isixhobo siyeka, ukuba umbhobho usasebenza, seta ipleyiti eyimfama kwivalve yokuvala.
3. Ukuba ifowuni i-multi-series, umbhobho oyintloko ovela ngaphandle kwendawo yomda uhlukaniswe ngamawaka amatshaneli ombhobho kuchungechunge ngalunye, kwaye i-valve ye-cutoff yombhobho ngamnye isetyenzisiwe kunye neplate yokuphelisa.
4. Xa isixhobo sifuna ukugcinwa rhoqo, ukuhlolwa okanye ukutshintshana, izixhobo ezibandakanyekayo kufuneka zibe zodwa ngokupheleleyo, kwaye ipleyiti eyimfama ibekwe kwi-valve yokusika.
5. Xa umbhobho wokutshaja noxinzelelo kunye nombhobho werhasi otshintshiweyo (ofana nombhobho wenitrogen kunye nombhobho womoya ocinezelweyo) ziqhagamshelwe kwisixhobo, ipleyiti eyimfama kufuneka isetwe kwivalve yokuvala.
6. Coca indawo ephantsi yezixhobo kunye nombhobho. Ukuba inkqubo yenkqubo kufuneka ifakwe phakathi kwinkqubo yokuqokelela edibeneyo, setha ipleyiti eyimfama emva kwevalve yokusika.
7. Iipleyiti ezingaboniyo okanye iiplagi zocingo kufuneka zimiselwe emva kweevalvu zemibhobho yokukhupha, imibhobho yokukhupha ulwelo kunye nemibhobho yesampulu yezixhobo kunye nemibhobho. Izinto ezingeyiyo ityhefu, ezingeyongozi kwimpilo kunye nezinto ezingaqhumisiyo azibandakanywanga.
8. Xa ukufakela kwakhiwa ngamanqanaba, ipleyiti eyimfama kufuneka ibekwe kwi-valve yokunqunyulwa kwemibhobho edibeneyo kunye nomnye, ukwenzela ukuba kube lula ukwakhiwa okulandelayo.
9. Xa isixhobo sikwimveliso eqhelekileyo, ezinye iipayipi ezincedisayo ezifuna ukunqunyulwa ngokupheleleyo kufuneka zixhotyiswe ngamacwecwe angaboniyo. ? [1]?
Imibandela efuna ingqalelo
1. Kwisiseko sokuhlangabezana neemfuno zenkqubo, seta iipleyiti ezingaboniyo ezimbalwa kangangoko.
2. Icwecwe elicwangcisiweyo eliyimfama kufuneka libonise ukuvulwa okuqhelekileyo okanye ukuvala okuqhelekileyo.
3. Inxalenye yeplate eyimfama ebekwe kwi-valve yokusika, phezulu okanye ezantsi, kufuneka igqitywe ngokuhambelana nesiphumo sokunqunyulwa, ukhuseleko kunye neemfuno zenkqubo.
