Kwiinkqubo zemibhobho yemizi-mveliso, ukukhethwa kweevalvu kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwenkqubo, ukuchaneka kolawulo, kunye nokuthembeka kwexesha elide. Ngelixa iivalvu zebhola kunye neevalvu zesango zihlala zikhethwa ukuze zisebenze ngokulula,iivalvu zeglobhuzidlala indima ebalulekileyo xa kufuneka ulawulo oluchanekileyo lokuhamba kwamanzi kunye nokuthomalalisa okuzinzileyo. Ukuqonda ukuba kufuneka ukhethe nini ivalvu yeglobe kunceda iinjineli, abaqhubi, kunye nabaphathi beeprojekthi ukuba bayile iinkqubo ezikhuselekileyo nezisebenzayo.
Xa Kufuneka Ulawulo Oluchanekileyo Lokuhamba Kwendlela
Ivalvu yeglobe yeyona ikhethwayo xa ukuchaneka kolawulo lokuhamba kwamanzi kubalulekile.Ngokungafaniyo neevalvu ezivuliweyo, uyilo lwe-linear motion lwevalvu yeglobe luvumela idiski ukuba ihambe kancinci kancinci iye okanye isuke kwisihlalo. Olu lwakhiwo lwenza ukuba ilungelelanise isantya sokuhamba kwamanzi ngendlela ethe tye neqikelelweyo kunokutshintsha ngequbuliso.
Kwizicelo apho ukuhamba kwamanzi kufuneka kulungiswe kakuhle—njengemigca yokulawula inkqubo, iinkqubo ze-bypass, okanye iisekethe zokulinganisela—ivalufu yeglobe inika ulawulo olungcono kakhulu kunevalufu yesango okanye yebhola.
Xa i-Throttling iyimeko eqhelekileyo yokusebenza
Iivalvu zeglobe zenzelwe ngokukodwa inkonzo yokuqhobosha.Kwiinkqubo ezininzi zoshishino, iivalvu azihlali zivuliwe okanye zivalwe ngokupheleleyo. Endaweni yoko, zisebenza kwiindawo ezivulekileyo ixesha elide. Iivalvu zesango kunye neevalvu zebhola azilungelekanga kwiimeko ezinjalo kuba ukuvulwa okungaphelelanga kunokubangela ukukhukuliseka kwesihlalo okanye ukuhamba kwamanzi okungazinzi.
Ivalvu yeglobe, ngokwahlukileyo, iphatha ukugoba kakuhle ngelixa inciphisa ukungcangcazela kunye nokuguguleka. Oku kuyenza ifaneleke kwezi zinto zilandelayo:Ulawulo lokuhamba komphunga,Ulawulo lwamanzi okupholisa,Uhlengahlengiso lweendaba zenkqubo,Imigca yezixhobo kunye neesampuli
Xa Kubandakanyeka Uxinzelelo Oluphezulu okanye Ubushushu Obuphezulu
Iivalvu zeglobe zisebenza kakuhle kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu.Ijiyometri yazo yangaphakathi ivumela uxinzelelo ukuba lusasazwe ngokulinganayo kwidiski nakwisihlalo. Xa zidityaniswe nezinto eziqinileyo ezifana nentsimbi yekhabhoni, intsimbi engatyiwayo, kunye nentsimbi ye-alloy, iivalvu zeglobe zihlala zisetyenziswa kwezi:Izityalo zombane,Iinkqubo zamanzi okusela iibhoyila,Imibhobho yokusasaza ngomphunga.Iiyunithi zokucubungula ioyile negesi.
Xa iimeko zenkqubo zinzima, iivalvu zeglobe zibonelela ngokusebenza okuzinzileyo kunye nobomi benkonzo obude.
Xa Ulawulo Lwendlela Yokuhamba Kwendlela Lubalulekile
Esinye isizathu sokukhetha ivalvu yeglobe yindlela echaziweyo yokuhamba kwayo.Iivalvu ezininzi zeglobe zenziwe ngendlela ethile yokungena kunye neyokuphuma. Le ndlela yokuhamba elawulwayo iphucula uzinzo lokugoba kwaye inciphisa ukuxinana kwiindawo ezivulekileyo ezingaphelelanga.
Kwiinkqubo apho ukuziphatha kokuhamba kwamanzi kufuneka kuqikeleleke—njengee-control loops okanye izitishi zokunciphisa uxinzelelo—le nto iba yinzuzo ebalulekileyo.
Xa Kulindeleke Utyando Oluqhubekayo
Iivalvu zeglobe zifanelekile kwiinkqubo ezifuna ukuvulwa nokuvalwa rhoqo.Ukuhamba okuthe tye kwesiqu kunciphisa umngcipheko wokutshayiswa ngequbuliso kumbhobho. Oku kuhamba okulawulwayo kunceda ukukhusela izixhobo ezisezantsi komlambo kwaye kuphucula ukhuseleko lokusebenza.
Kwiinkqubo ze-HVAC, kwizixhobo zoshishino, nakwiindawo zokusetyenziswa elwandle apho iivalvu zilungiswa rhoqo, iivalvu zeglobe zibonelela ngokusebenza okuthembekileyo nokuphindaphindwayo.
Xa Ulawulo Lokuvuza Lubaluleke Ngakumbi Kunokulahlekelwa Nguxinzelelo
Liyinyaniso elokuba iivalvu zeglobe zenza ukwehla koxinzelelo oluphezulu kuneevalvu zebhola okanye zesango. Nangona kunjalo, xa ukuvalwa okuqinileyo kunye nokuzinza kokulawula ukuhamba kwamanzi kubaluleke kakhulu kunokunciphisa ukulahleka koxinzelelo, ivalvu yeglobe yeyona ndlela ilungileyo.
Izicelo ezibandakanya:Umphunga,Igesi,Ulwelo oluyingozi okanye olunexabiso eliphezulu
kudla ngokubaluleka ukusebenza kokutywina kunye nokuchaneka kokulawula ngaphezu kokusebenzisa amandla kakuhle.
