1. Okumaphakathi: Ngesikhathi sokusetshenziswa kwe-valve yebhola yensimbi engagqwali, kufanele kuqashelwe ukuthi i-medium esetshenzisiwe ingahlangabezana yini nemingcele ye-valve yebhola yamanje.Uma i-medium esetshenziswa kuyigesi, ngokuvamile kuyanconywa ukusebenzisa uphawu oluthambile.Uma kuwuketshezi, uphawu oluqinile noma uphawu oluthambile lungakhethwa ngokuya ngohlobo loketshezi.Uma konakala, ulwelwesi lwe-fluorine noma izinto ezilwa nokugqwala kufanele zisetshenziswe esikhundleni salokho.
2. Izinga lokushisa: Ngesikhathi sokusebenzisa i-valve yebhola yensimbi engagqwali, kufanele kuqashelwe ukuthi izinga lokushisa eliphakathi nendawo elisebenzayo lingahlangabezana yini nemingcele ye-valve yebhola ekhethiwe njengamanje.Uma izinga lokushisa lingaphezu kwama-degrees angu-180, izinto zokuvala kanzima noma izinto ezisezingeni eliphezulu ze-PPL kufanele zisetshenziswe.Uma izinga lokushisa lingaphezu kwama-degrees angu-350, izinto zokushisa eziphezulu kufanele zicatshangelwe ukuthi zithathe indawo.
3. Ukucindezela: Inkinga evame kakhulu ye-valve yensimbi engenasici esetshenziswayo ingcindezi.Ngokuvamile, siphakamisa ukuthi izinga lokucindezela kufanele libe izinga eliphezulu.Isibonelo, uma ingcindezi yokusebenza ingu-1.5MPa, siphakamisa ukuthi izinga lokucindezela akufanele libe ngu-1.6MPa, kodwa libe ngu-2.5MPa.Izinga eliphakeme kangaka lokucindezela lingaqinisekisa ukusebenza kokuphepha kwepayipi ngesikhathi sokusetshenziswa.
4. Ukugqoka: Ngesikhathi sokusebenzisa, sizothola ukuthi ezinye izidingo zezimboni kanye nezimayini ezikusayithi ziphakeme kakhulu, njengokuthi i-medium iqukethe izinhlayiya eziqinile, isihlabathi, amatshe amatshe, i-slurry slag, i-lime kanye neminye imidiya.Ngokuvamile sincoma ukuthi kusetshenziswe izimpawu ze-ceramic.Uma izimpawu ze-ceramic zingakwazi ukuxazulula inkinga, amanye ama-valve kufanele asetshenziswe esikhundleni salokho.
