Kwintsimi yobunjineli bezoshishino, iivalve zebhola zizinto eziphambili ezidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kunye neegesi. Ezi zivalo ziyaziwa ngokuguquguquka kwazo, ukuthembeka, kunye nokusebenza kakuhle, okwenza ukuba zibe lukhetho oludumileyo kumashishini ahlukeneyo. Ukusuka kwi-oyile kunye negesi ukuya kunyango lwamanzi kunye nokucutshungulwa kweekhemikhali, iivalve zebhola zibalulekile ekuqinisekiseni ukulawulwa okuhamba kakuhle kunye nokuchanekileyo.
Yintoni eyenza iivalvu zebhola zahluke kwezinye iintlobo zevalve luyilo lwazo olulula kodwa olusebenzayo. Ivalve yebhola inediski engqukuva enomngxuma embindini ojikelezayo ukuvumela okanye ukuthintela ukuphuma kwamanzi. Olu luyilo lubonelela ngeenzuzo ezininzi, kubandakanya ukuhla koxinzelelo oluncinci, ukutywinwa okuqinileyo, kunye nokusebenza ngokukhawuleza. Ngoko ke, iivalve zebhola zisetyenziswa ngokubanzi kwizicelo ezifuna ukuvala ngokukhawuleza nangokuchanekileyo.
Enye yeenzuzo eziphambili zeevalve zebhola kukukwazi kwabo ukuphatha uluhlu olubanzi lweengcinezelo kunye namaqondo okushisa. Nokuba ngumphunga woxinzelelo oluphezulu kwiplanti yamandla okanye imichiza eyonakalisayo kwiplanti yokuvelisa, iivalvu zebhola ziyilelwe ukuba zimelane neemeko ezinzima ngaphandle kokubeka esichengeni ukusebenza. Oku kubenza babe ukhetho oluthembekileyo kwiinkqubo ezibalulekileyo apho ukhuseleko kunye nokusebenza kakuhle kubalulekile.
Ukongeza kulwakhiwo lwazo oluqinileyo, iivalve zebhola ziyaziwa ngeemfuno zazo zokugcinwa okuphantsi. Xa kuthelekiswa nezinye iintlobo zeevalve, iivalve zebhola zineenxalenye ezincinci ezihambayo kwaye azikwazi ukugqoka kunye nokukrazula, okukhokelela kubomi obude benkonzo kunye nexesha elincinci lokuphumla. Oku akugcini nje kuphela iindleko zeshishini kodwa kwakhona kuqinisekisa ukusebenza okungaphazamisekiyo, ngaloo ndlela kwandisa imveliso jikelele.
Enye inzuzo yeevalvu zebhola kukuguquguquka kwazo kwizicelo. Nokuba yeyokuvula/yokuvala ulawulo, ukungqusha okanye ukuphambukisa, iivalvu zebhola zinokulungiswa ukuze zihlangabezane neemfuno ezithile. Oku kuguquguquka kubenza bafaneleke kumashishini ahlukeneyo, ukusuka kwizityalo zepetrochemical kunye nezixhobo zokucokisa ukuya kwiindawo zokuxutywa kwamayeza kunye nokutya.
Ukongezelela, ukuqhubela phambili kwezobuchwepheshe kuye kwakhokelela ekuphuhlisweni kweentlobo ezahlukeneyo zeevalve zebhola ukuhlangabezana neemfuno ezithile. Ngokomzekelo, iivalve zebhola ezifakwe kwi-trunnion zenzelwe ukusetyenziswa koxinzelelo oluphezulu, ngelixa iivalve zebhola ezidadayo zifanelekile kuxinzelelo oluphantsi kunye nokusetyenziswa kwenjongo jikelele. Ukongezelela, izinto ezifana nensimbi engenasici, ubhedu kunye ne-PVC zisetyenziselwa ukuqinisekisa ukuhambelana neendaba ezahlukeneyo kunye neemeko zokusingqongileyo.
Uphuhliso lwetekhnoloji yevalve yebhola lukwakhokelele ekudityanisweni kweenkqubo ezizisebenzelayo kunye nolawulo, ziphucula ngakumbi ukusebenza kwazo. Ngokudibanisa ii-activators kunye ne-positioners, iivalve zebhola zingasetyenzwa kwaye zibekwe esweni kude, zivumela ulawulo oluchanekileyo kunye nengxelo yedatha yexesha langempela. Eli nqanaba le-automation aligcini nje ukuphucula ukusebenza kakuhle, kodwa linegalelo ekukhuseleni ngokubanzi kunye nokuthotyelwa kokulawula.
Isishwankathelo, iivalve zebhola ziye zaba yinto efunekayo kwishishini lanamhlanje, ukudibanisa izinto ezininzi, ukusebenza kunye nokuthembeka. Ukukwazi kwabo ukujongana noluhlu olubanzi lweengcinezelo kunye namaqondo okushisa, iimfuno zokugcinwa okuphantsi, kunye nokulungelelaniswa kwezicelo ezahlukeneyo kubenza ukhetho lokuqala lokulawula ukuhamba. Njengoko ishishini liqhubeka nokukhula, indima yeevalvu zebhola ekuqinisekiseni ukusebenza ngokufanelekileyo nangokukhuselekileyo isabalulekile, iqinisa indawo yazo njengento ebalulekileyo yobunjineli boshishino.
