Xa sithetha ngevalve yebhabhathane, kufuneka sikhankanyeivelufa yebhabhathanekwayeiflange butterfly valvekuqala, kodwa yintoni umahluko phakathi kwe-wafer kunye ne-flange butterfly valve? Ndiza kudwelisa amanqaku amaninzi ngezantsi:
1. Ingcaciso:
Yintoni iWafer Butterfly Valves?
Ivalve yeButterfly Wafer: Le valve yenzelwe ukuba ilingane phakathi kweeflange ezimbini. Babizwa ngokuba “yi-wafer” Kuba inkangeleko yabo ebhityileyo ibonakala ngathi yi-wafer. Kufuneka sifake i-wafer kunye ne-stud bolts ende, iqhube ngobude bevalve ukuyikhusela phakathi kweeflange.
Yintoni i-Flange Butterfly Valves?
Ivalve yeFlange Butterfly: Le valve ineeflange zayo kumacala amabini omzimba wevalvu, ezibotshelelwe kwiiflange ezihambelanayo kumbhobho.
2. ImiGangatho yoQhagamshelwano:
a) Ivalve yeButterfly yeWafer: Le valve yesiqhelo yeyomgangatho woqhagamshelo oluninzi, ngoko ke umthengi ukhetha ukuthenga uhlobo lwewafer xa ungazi ukuba yintoni uqhagamshelwano lweflange yombhobho.
b) Ivalve yebhabhathane yeFlange: Ivalve yebhabhathane eneflethi ikholisa ukudityaniswa okusemgangathweni omnye. Unokuyiqhagamshela kuphela ngeeflange eziqhelekileyo ezihambelanayo.
3. Isicelo:
a) Ivalufa yeBhavavane yeWafer: Edla ngokusetyenziswa kwizicelo zesithuba esimxinwa kunye neenkqubo apho ukulula kofakelo kuyinto ephambili. Ifanelekile kwizicelo zoxinzelelo oluphantsi ukuya oluphakathi.
b) Ivalve yebhabhathane eneFlanged: Ukuba unendawo eyaneleyo yokufaka ivalve, ivalve yebhabhathane yohlobo lweflange yeyona ndlela ilungileyo, kuba inokusebenza ngoxinzelelo oluphakathi ukuya phezulu kunye nomphezulu wokutywina.
4. Iindleko:
a) Ivalufa yeBhavane eWafer: Ngokuqhelekileyo, amaxabiso aphantsi kuneevalvu zeflange ngenxa yoyilo lwazo olulula kunye neenxalenye ezimbalwa.
b) Ivalve yebhabhathane yeFlange: Isixhobo esongezelelweyo kunye nobunzima kuyilo lubenza babize kakhulu.
Ukukhetha phakathi kwezi ntlobo zimbini zeevalvu zebhabhathane kuxhomekeke kwiimfuno ezithile zesicelo, kubandakanya imiqobo yendawo, iimfuno zoxinzelelo, ukuphindaphindwa kokugcinwa, kunye nokuqwalaselwa kohlahlo lwabiwo-mali.
Umzi-mveliso we-valve we-Zfa ngumzi-mveliso wevalufa we-butterfly onamava okuvelisa iminyaka engaphezu kwe-15, ubonelela ngevalve yebhabhathane, ivalve yebhabhathane, i-lug butterfly valve, amalungu evalvu efana nomzimba wevalvu, idiski yevalvu, isihlalo sevalve kunye nebhabhathane levalve yesandla njl njl.
