I-valves yebholazizinto ezibalulekileyo kwiinkqubo zanamhlanje zolawulo, ezaziwa ngokuqinileyo, ukuthembeka kunye nokusebenza kakuhle. Uphuhliso lwabo luguqukele kumashishini ahlukeneyo, ukusuka kwii-plumbing kunye neoyile yokuqhubela phambili kweekhemikhali kunye nokuveliswa kwamandla. Kodwa le nto iqala njani? Ukuqonda imbali yeebhova zebhola kunika ukuqonda malunga nendlela yobunjineli obuyenze njani umhlaba wezinto eziguqukayo.
Umxholo wokulawula ukuhamba kwamanzi emva kweminyaka engamawakawaka. Impucuko yakudala, kubandakanya namaRoma namaGrike, iinkqubo zeVoodve zeVolide zokulawula ukulawula amanzi. Ezi zixhobo zokuqala, ngokuqhelekileyo isango okanye i-plugi yeplagi, zazilula kodwa zihlala zithambekele ekuvusweni, zinxibe, kunye nokungasebenzi kakuhle.
Ukukhangela iindlela ezingcono ze-velis ziqhubekile kuwo wonke amaXesha Aphakathi kunye nohlaziyo lwemizi-mveliso. Ngemfuno eyandayo yolawulo olufanelekileyo lokuhamba kunye nokuvuza ngokuvuza kwamashishini anjengamandla eSteam kunye nemveliso yemichiza, iinjineli zafuna ukuphuculwa koyilo lwevali.
Ukuqulunqwa kwevalve yebhola yanamhlanje kunokulandelwa emva kwinkulungwane yama-20. Ngelixa ivelaphi ivela ngandlel 'ithile icacile, imizobo yoyilo yasekuqaleni ivele nge-1870s, kodwa yayingazali ngokubanzi ngenxa yokusikelwa umda kwezinto. Kwakungekade kube yinkulungwane ye-20 ukuba i-valves yebhola ibone inkqubela phambili ebalulekileyo.
Ngeminyaka yee-1940, ubuchule boMveliso kwizixhobo kunye nemveliso evumele iinjineli zokuphucula uyilo lwevali yebhola. Ukuqaliswa kwe-polymers yokwenziwa, ngakumbi i-teflon (PTPO), yenze ukuba idalwe i-ofisi yohlala-tywina, i-airac. Olu hlaselo lukhokelele ekusebenziseni ngokubanzi kweI-valves yebholakwizicelo zemveliso.
Uyilo kunye nokusebenza
Ivalve yebhola iquka i-gobl, indawo ethe tye (ibhola) ejikeleza ngaphakathi kwendlu yokulawula ukuhamba kwamanzi. Xa ivalve ivulekile, umngxunya kwibhola eguqukayo nombhobho, uvumela ulwelo ukuba ludlule. Xa ivaliwe, indawo eqinileyo yebhola ibhloka isicatshulwa, ikhupha ukungena ngokupheleleyo. Le ndlela ilula kodwa isebenzayo ibonelela ngeenzuzo ezininzi kwiSango leMvelo okanye i-Globle Valhls, kubandakanya:
● Ukusebenza ngokukhawuleza nokulula (ihlala inesiphatho sekota)
● Ukuvuza amancinci ngenxa yeepropathi zokutywina
● Ukuqina okuphezulu kunye nokuxhathisa kuxinzelelo kunye nokwahluka kweqondo lobushushu
● Uyilo lwe-Compact kunye neemfuno zolondolozo olusezantsi
Izicelo zanamhlanje kunye nenkqubela phambili
Ukusukela ekuthandeni kwabo phakathi kwenkulungwane yama-20,I-valves yebholaiguqukele ekuhlangabezeni iimfuno zamashishini ahlukeneyo. Ngoku basetyenziswa:
● Imibhobho ye-oyile kunye negesi yokulawula ioyile emdaka kunye nokuhamba kwegesi yendalo
● Izityalo zamanzi izityalo zokulawula iinkqubo ezicocekileyo nenkunkuma
● Amashishini amayeza kunye nokutya apho iimeko zococeko zibalulekile
● I-HVAC kunye neenkqubo zokwenza iziqhulo zeMigaqo yeShumi
Ukuhambela phambili kwezobugcisa kuyaqhubeka ukuphucula uyilo lwe-valve. Namhlanje, i-automated kwaye i-smart kunye ne-smart-smart kunye nezakhono zolawulo ezikude ziba senza umgangatho kwizicwangciso zemizi-mveliso, ukwanda kokusebenza nokhuseleko.
Iivalve yebholayiTestamente kwiNgozi yoBuntu kubuNjineli kunye nolawulo lwamanzi. Ukusuka kwiicebo layo zokuqala ngenkulungwane ye-19 ukuya kwiinguqulelo ezifanelekileyo nethembekileyo esisebenzayo, le nto intsha idlale indima ebalulekileyo kuphuhliso lwamashishini. Njengoko itekhnoloji iqhubeka, ivilbe yeBhola iya kuqhubeka nokuvela, ukuphucula ukusebenza kwazo kunye nokungasebenzi kwimizi-mveliso yehlabathi.
