Umbhobho kunye neValve yezeMizi-mveliso: Isishwankathelo esipheleleyo seValve zeBhola kunye neSango
Kwimiba yeenkqubo zemibhobho yemizi-mveliso, iivalvu zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo. Phakathi kweentlobo ngeentlobo zeevalvu, iivalvu zebhola kunye neevalvu zesango zezona zimbini zezona zisetyenziswa kakhulu. Uhlobo ngalunye luneengenelo zalo ezikhethekileyo kunye nokusetyenziswa kwalo, nto leyo eyenza zibe yinxalenye ebalulekileyo kumashishini ahlukeneyo.
Iivalvu zeBholazaziwa ngokusebenza kwazo ngokukhawuleza kunye nokukwazi kwazo ukuvala kakuhle. Zisebenzisa idiski engqukuva, okanye ibhola, ukulawula ukuhamba kolwelo. Xa ibhola ijikeleziswa, ivumela okanye ivale ukuhamba, nto leyo eyenza ukuba ilungele ukusetyenziswa okufuna ukuvalwa ngokukhawuleza. Iivalvu zebhola ziyafumaneka ngezinto ezahlukeneyo, kunyeiivalvu zebhola zentsimbi yekhabhonikwaye iivalvu zebhola zentsimbi engagqwaliyo zezona zikhethwa kakhulu. Iivalvu zebhola zentsimbi yekhabhoni zihlala zisetyenziswa kwiindawo ezinoxinzelelo oluphezulu ngenxa yokuqina kwazo nokuqina kwazo, ngelixa iivalvu zebhola zentsimbi engagqwaliyo zikhethwa kwiindawo ezirhabaxa ngenxa yokumelana kwazo nomhlwa kunye ne-oxidation.
Kwelinye icala,Iivalvu zeSangoZenzelwe ukusetyenziswa apho uxinzelelo oluncinci lufunekayo. Zisebenza ngokuphakamisa isango liphume kwindlela yolwelo, okuvumela ukuhamba komgca othe tye. Olu yilo lwenza iivalvu zesango zifaneleke ngokukodwa kulawulo lokuvula/ukuvala endaweni yokubhoboza. Njengeevalvu zebhola, iivalvu zesango zikwafumaneka kwiindidi zentsimbi yekhabhoni kunye nentsimbi engagqwaliyo. Iivalvu zesango lentsimbi yekhabhoni zihlala zisetyenziswa kusetyenziso lwamanzi, ioyile, kunye negesi, ngelixa iivalvu zesango lentsimbi engagqwaliyo zithandwa kakhulu kushishino lokucubungula iikhemikhali kunye nokutya ngenxa yeempawu zazo zococeko.
Ukuqukumbela, ukhetho phakathi kweevalvu zebhola kunye neevalvu zesango, kunye nokukhethwa kwezinto ezifana nentsimbi yekhabhoni kunye nentsimbi engatyiwayo, kuxhomekeke kwiimfuno ezithile zesicelo semizi-mveliso. Ukuqonda iimpawu kunye neenzuzo zohlobo ngalunye lwevalvu kubalulekile ekwenzeni ngcono ukusebenza kunye nokuthembeka kweenkqubo zemibhobho yemizi-mveliso. Nokuba ujongene neendawo ezinoxinzelelo oluphezulu okanye izinto ezirhabaxa, ukukhetha ivalvu efanelekileyo kubalulekile ekuqinisekiseni ukusebenza okusebenzayo nokukhuselekileyo.
