I-valve yebhola njengohlobo oluvame ukusetshenziswa lwe-valve emkhakheni wezimboni, ukukhethwa kwayo kwezinto ezibonakalayo kuthinta ngokuqondile ukusebenza kwayo kanye nobubanzi bokusebenza. Lesi sihloko sizokunikeza isingeniso esiningiliziwe sezinto ezihlukahlukene zama-valve ebhola ukukusiza ukuthi uqonde kangcono futhi ukhethe imikhiqizo ye-valve yebhola.
1. Uhlolojikelele lwama-valve ebhola
I-valve yebhola iyibhola njengezingxenye zokuvula nokuvala ze-valve, enesakhiwo esilula, ukusebenza okulula, ukusebenza kahle kokuvala uphawu nezinye izici, ezisetshenziswa kabanzi ku-petroleum, amakhemikhali, igesi yemvelo, ukwelashwa kwamanzi nezinye izimboni zezimboni. Izinto eziyinhloko ze-valve yebhola zihlanganisa izici ezilandelayo:
Izinto ezi-1 zebhola: Ibhola liyingxenye eyinhloko ye-valve yebhola, ukukhethwa kwayo kwezinto ezibonakalayo kuthinta ngokuqondile ukusebenza kokuvala kanye nempilo yesevisi ye-valve yebhola.
2. Impahla yomzimba ye-valve: Umzimba we-valve uyingxenye eyinhloko ye-valve yebhola, futhi ukukhethwa kwezinto ezibonakalayo kunquma amandla nokumelana nokucindezela kwe-valve yebhola.
3. Izinto zokuvala: Impahla yokuvala iwukhiye wokuqinisekisa ukusebenza kokuvala kwe-valve yebhola, futhi idinga ukumelana nokuguga okuthile, ukumelana nokugqwala kanye nokumelana nokuguga.
Okwesibili, China ball valve materials isingeniso enemininingwane
1. Izinto ezibonakalayo
(1) Insimbi ye-Carbon: Ibhola le-carbon steel linamandla amahle nokumelana nokugqoka, lilungele izinhlelo zokulawula amapayipi emkhakheni wezimboni jikelele.
(2) Insimbi engagqwali: Ibhola lensimbi engagqwali linokumelana nokugqwala okuhle, lilungele imidiya egqwalayo kanye nezidingo zokuhlanzeka okuphezulu.
(3) i-carbide enosimende: ibhola le-carbide elihlanganisiwe elinokuqina okuphezulu, ukumelana nokugqoka okuphezulu, elifanele izinga lokushisa eliphezulu, ukucindezela okukhulu, izimo zokugqoka eziphezulu.
(4) I-Ceramic: ibhola le-ceramic linokumelana okuhle kokugqokwa, ukumelana nokugqwala kanye nobulukhuni obuphezulu, ifanele ukugqoka okuphezulu, imidiya egqwalayo kanye nezimo zokushisa eziphezulu.
2. Impahla yomzimba
(1) Insimbi ye-Carbon: umzimba we-carbon steel valve unamandla amahle nokumelana nokucindezela, ofanele amasistimu okulawula amapayipi emkhakheni wezimboni jikelele.
(2) Insimbi engagqwali: Umzimba wensimbi engagqwali unokumelana nokugqwala okuhle, ulungele imidiya egqwalayo kanye nezidingo zokuhlanzeka okuphezulu.

3. Izinto zokuvala
(1) Irabha ye-Fluorine: Irabha ye-fluorine inokumelana nokugqwala okuhle, ukumelana nokugqoka kanye nezindawo zokulwa nokuguga, ifanele imidiya egqwalayo nezimo zokushisa eziphezulu.
(2) I-Polytetrafluoroethylene: i-polytetrafluoroethylene inokumelana nokugqwala okuhle kakhulu, ukumelana nokugqoka kanye nezindawo zokulwa nokuguga, ezifanele izinhlobonhlobo zemithombo yezindaba ezonakalisayo kanye nezimo zokushisa eziphezulu.
(3) I-graphite: i-graphite inokumelana nokugqwala okuhle kakhulu, ukumelana nokugqoka kanye nezindawo zokulwa nokuguga, ezifanele ukushisa okuphezulu, ukucindezela okuphezulu nezimo zemidiya ezigqwalayo.
Iii. Isiphetho
Ukukhethwa kwezinto ezibonakalayo kwe-valve yebhola kunomthelela obalulekile ekusebenzeni kwayo kanye nobubanzi bokusebenza. Ukuqonda izinto ezihlukahlukene zama-valve ebhola kusiza ukukhetha kangcono imikhiqizo efanele, ukuze kuzuzwe umphumela omuhle wokusebenzisa. Ngithemba ukuthi lesi sihloko singakunikeza ireferensi ewusizo lapho ukhetha i-valve yebhola.
