Kwiinkqubo zemibhobho yoshishino, ukhetho lwevalvu lubalulekile, ngakumbi iivalve zebhabhathane. Iivalve zebhabhathane zisetyenziswa kakhulu ngenxa yesakhiwo sazo esilula, ukuxhathisa ulwelo oluphantsi, kunye nokusebenza ngokulula. Iintlobo eziqhelekileyo zevalve yebhabhathane ziqukaivelufa yebhabhathane, ivalve yebhabhathane eneflanged, kwayeivalve yebhabhathane ekhutshiweyo. Xa ukhetha uqhagamshelo lwevalve ukuya kumbhobho, kubalulekile ukuqonda iimpawu zevalve yebhabhathane ezahlukeneyo kunye neemeko ezisebenzayo.
Okokuqala, the ivelufa yebhabhathaneluhlobo oluqhelekileyo lwevalve yebhabhathane, edla ngokusetyenziswa phakathi kombhobho. Uyilo lwayo luvumela ukuba lunyanzeliswe ngokuthe ngqo phakathi kwamacandelo amabini emibhobho, ukwenza lula ukudibanisa kunye nokwenza kube lula usetyenziso olunendawo encinci. Izibonelelo zevalve yebhabhathane ye-wafer ibandakanya ubunzima bayo obulula kunye nokulula kofakelo, iyenze ilungele ukulawula uxinzelelo oluphantsi kunye noxinzelelo oluphakathi. Xa ukhetha ivalve yebhabhathane, qinisekisa ukuba imilinganiselo yeflange yombhobho ihambelana nemilinganiselo yevalvu ukuqinisekisa ukutywinwa okukhuselekileyo.
Okwesibini,iivalve zebhabhathane ezinecalaziqhagamshelwe kwimibhobho ngeeflange. Olu xhulumaniso lubonelela ngokutywinwa okuphuculweyo kunye nokuzinza, okwenza kube ngokufanelekileyo kwizicelo zoxinzelelo oluphezulu kunye nobushushu obuphezulu. Ukufakwa kweevalve zebhabhathane eziphothiweyo kunzima, kufuna iibholiti zokudibanisa ivalve kwiflange yombhobho. Xa ukhetha i-valve ye-butterfly ye-flangd, ngaphezu kokuqwalasela izinto ze-valve kunye nobukhulu, kubalulekile ukuqwalasela umgangatho we-flange (njenge-ANSI, i-DIN, njl.) kunye nezinto zokutywinwa ukuqinisekisa ukhuseleko kunye nokuthembeka phantsi kweemeko eziphezulu zoxinzelelo.
Ekugqibeleni,ivalve yebhabhathane ekhutshiweyosisivalo esiqhagamshelwe ngumjelo kwaye sisoloko sisetyenziselwa ukuqhawula kunye nokugcinwa ngokukhawuleza. Iivalve ze-butterfly ezigudileyo zilula kakhulu ukuzifaka kunye nokususa, okwenza ukuba zilungele iinkqubo zokubhobhoza ezifuna ukutshintshwa rhoqo okanye ukucocwa. Xa ukhetha ivalve yebhabhathane egrunjiweyo, qwalasela imathiriyeli yombhobho kunye nedayamitha ukuqinisekisa ukuba umjelo unokubamba ngokukhuselekileyo ivalve kwaye uthintele ukuvuza.
Xa ukhetha indlela yokudibanisa phakathi kwevalve kunye nombhobho, ukongeza ekuqwalaseleni uhlobo lwevalve, kufuneka uqwalasele ezi zinto zilandelayo:
1. Iimpawu ze-Fluid: Ulwelo oluhlukeneyo (njengegesi, ulwelo, i-slurry, njl.) zineemfuno ezahlukeneyo zeevalvu, ngoko kufuneka ukhethe uhlobo olufanelekileyo lwevalve kunye nendlela yokudibanisa.
2. Uxinzelelo lokusebenza kunye nobushushu: Ngaphantsi koxinzelelo oluphezulu kunye neemeko eziphezulu zokushisa, i-valve ye-butterfly ye-flange ingaba yinto engcono kakhulu, ngelixa phantsi kweemeko eziphantsi koxinzelelo, i-wafer butterfly valve okanye i-grooved butterfly valve inokufaneleka ngakumbi.
3. Isithuba sofakelo: Xa isithuba sinqongophele, uyilo lwevalve yebhabhathane yebhabhathane inokonga indawo, ngelixa ivalve yebhabhathane egrunjiweyo ibonelela ngokuguquguquka okukhulu.
4. Iimfuno zogcino: Ukuba isixokelelwano sombhobho sifuna ukugcinwa rhoqo, into ekhawulezayo yokuqhawula ivalve yebhabhathane egrunjiweyo iya kuphucula kakhulu ukusebenza kakuhle.
Isishwankathelo, ukukhetha ivalve yebhabhathane efanelekileyo kunye nendlela yoqhagamshelo yayo ibalulekile ekuqinisekiseni ukusebenza ngokufanelekileyo nangokukhuselekileyo kwesixokelelwano sakho semibhobho. Ukuqonda iimpawu kunye neemeko ezifanelekileyo zeentlobo ezahlukeneyo zevalve yebhabhathane kuya kukunceda wenze ukhetho olunolwazi ngakumbi kwizicelo ezisebenzayo. Nokuba ngabaivelufa yebhabhathane, ivalve yebhabhathane eneflanged, ivalve yebhabhathane ekhutshiweyo, indlela yokudibanisa echanekileyo inokuphucula ukusebenza ngokubanzi kunye nokuthembeka kwenkqubo.
