Siyabona ukuba ivili lesandla sevalve kunye nomqheba wevalve yebhabhathane ziyafana kakhulu. Abanye abantu baya kucinga ngempazamo ukuba bayinto enye, kodwa ngokwenene bahlukile.
Ukusebenza kokutywina komqheba wevalve yebhabhathane kunye nevili lesandla sevalve kwahlukile. Siyabona ukuba yeyiphi ivalve yebhabhathane eqhelekileyo kunye nevalve yesango enoxinzelelo olufanayo kunye nedayamitha yegama lesiphambo sebhabhathane enokuqina okungcono kwaye akulula ukuvuza. Lo ngumahluko.
Ezi zithuba zimbini nazo zahlukile, nto leyo ewumahluko ukuba kutheni iivalvu zesango zingasetyenziswa kwezinye iindawo kwaye zingasetyenziswa kwezinye iindawo. Ngenxa yezinye izithintelo zendawo, inyusa kakhulu ubunzima bofakelo kunye nobubanzi besicelo. Iivalve zesango zinomthamo omncinci kunye nendawo encinci.
Ivalve yebhabhathane inkulu ngomthamo kwaye incinci esithubeni, ngoko ke kufuneka sinikele ingqalelo kule ngongoma kwaye ibalulekile xa sikhetha. Nangona imisebenzi yezi zimbini ifana, iyantlukwano phakathi kwayo kufuneka iqondwe.
Umda wokulingwa kwezi zibini nawo wahlukile, kwaye amasimi abandakanyekayo nawo ahluke kakhulu, umzekelo, kulawulo lwerhasi yesibambo sevalve yebhabhathane ezininzi -ezinjongo kushishino lwe-asidi ye-sulfuric.
