I-valve yebhola njengohlobo olusetyenziswa ngokuqhelekileyo kwi-valve kwintsimi yoshishino, ukukhethwa kwayo kwezinto eziphathekayo kuchaphazela ngokuthe ngqo ukusebenza kwayo kunye nobubanzi besicelo. Eli nqaku liza kukunika intshayelelo eneenkcukacha kwizinto ezahlukeneyo zeevalvu zebhola ukukunceda uqonde ngcono kwaye ukhethe iimveliso zevalve yebhola.
1. Isishwankathelo seevalvu zebhola
I-valve yebhola yibhola njengeendawo zokuvula kunye nokuvala i-valve, enesakhiwo esilula, ukusebenza okulula, ukusebenza kakuhle kokutywinwa kunye nezinye iimpawu, ezisetyenziswa ngokubanzi kwi-petroleum, imichiza, igesi yendalo, unyango lwamanzi kunye nezinye iindawo zoshishino. Izinto eziphambili zevalve yebhola ziquka le miba ilandelayo:
Izinto zebhola ze-1: ibhola liyinxalenye ephambili ye-valve yebhola, ukukhethwa kwayo kwezinto eziphathekayo kuchaphazela ngokuthe ngqo ukusebenza kokutywinwa kunye nobomi benkonzo ye-valve yebhola.
2. Isixhobo somzimba we-valve: Umzimba we-valve uyinxalenye ephambili ye-valve yebhola, kwaye ukhetho lwezinto eziphathekayo lumisela amandla kunye nokuxhatshazwa koxinzelelo lwe-valve yebhola.
3. Izinto zokutywina: Izinto zokutywina ziyisitshixo sokuqinisekisa ukusebenza kokutywinwa kwe-valve yebhola, kwaye kufuneka ibe nokumelana okuthile, ukuxhathisa ukubola kunye nokuguga.
Okwesibini, izixhobo zevalve yebhola yaseTshayina zintshayelelo ezineenkcukacha
1. Izinto eziphathekayo
(1) Intsimbi yeCarbon: ibhola ye-carbon steel inamandla afanelekileyo kunye nokumelana nokugqoka, ifanelekile kwiinkqubo zokulawula umbhobho kwindawo yoshishino jikelele.
(2) Insimbi engenasici: ibhola yensimbi engenasici inokumelana ne-corrosion, ilungele imidiya ephazamisayo kunye neemfuno zokucoceka okuphezulu.
(3) i-carbide ene-cemented: ibhola ye-carbide ene-cemented enobunzima obuphezulu, ukuxhathisa ukugqoka okuphezulu, ukulungele ubushushu obuphezulu, uxinzelelo oluphezulu, iimeko zokugqoka eziphezulu.
(4) I-Ceramic: ibhola ye-ceramic inokumelana nokunxiba kakuhle, ukuxhathisa kwe-corrosion kunye nobunzima obuphezulu, ilungele ukunxiba okuphezulu, imidiya eyingozi kunye neemeko zobushushu obuphezulu.
2. Izinto zomzimba
(1) I-Carbon steel: umzimba we-carbon steel valve unamandla amahle kunye nokuxhatshazwa koxinzelelo, ofanelekileyo kwiinkqubo zokulawula umbhobho kwindawo yoshishino jikelele.
(2) Insimbi engagqwali: Umzimba wensimbi engenasici unokumelana ne-corrosion, ifanelekile kwimithombo yeendaba ezonakalisayo kunye neemfuno zokucoceka okuphezulu.
(3) Intsimbi yokuphosa: umzimba wevalve yentsimbi unamandla aphezulu kunye nokumelana noxinzelelo, ulungele ubushushu obuphezulu, uxinzelelo oluphezulu lwamasimi amashishini.
3. Izinto zokutywina
(1) Irabha ye-Fluorine: irabha ene-fluorine inokumelana nokugqwala okuhle, ukuxhathisa ukunxiba kunye neempawu zokuguga, ezifanelekileyo kwimithombo yeendaba ezonakalisayo kunye neemeko zobushushu obuphezulu.
(2) I-Polytetrafluoroethylene: i-polytetrafluoroethylene ine-corrosion resistance resistance, i-anti-corrosion resistance, i-anti-aging properties, ifanelekile kwiindidi zeendaba ezinobungozi kunye neemeko eziphezulu zokushisa.
(3) I-graphite: i-graphite inokumelana nokugqwesa okugqwesileyo, ukuxhathisa ukunxiba kunye neempawu zokuguga, ezifanelekileyo kubushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko zeendaba ezitshabalalisayo.
Iii. Ukuqukumbela
Ukukhethwa kwezinto eziphathekayo kwe-valve yebhola kunempembelelo ebalulekileyo ekusebenzeni kwayo kunye nobubanzi bokusetyenziswa. Ukuqonda izinto ezahlukeneyo zeevalve zebhola kunceda ukukhetha ngcono iimveliso ezifanelekileyo, ukuze ufezekise umphumo wokusetyenziswa. Ndiyathemba ukuba eli nqaku lingakunika ireferensi eluncedo xa ukhetha ivalve yebhola.
