Ukubaluleka
Iivalvu zidlala indima ebalulekileyo kumashishini aqala kwioyile negesi ukuya kwiinkqubo zemibhobho kunye nokufudumeza. Ezi zixhobo zincinci zilawula ukuhamba kolwelo kunye neegesi, ziqinisekisa ukusebenza ngokufanelekileyo kunye nokhuseleko. Nangona kunjalo, iivalvu ngamanye amaxesha zinokuba nzima ukuzifikelela okanye ukuzisebenzisa ngenxa yendawo okanye uyilo lwazo. Kwimeko enjalo, i-aulwandiso lwevalvuibalulekile. Kweli nqaku, siza kuhlola ukubaluleka kokwandiswa kweevalvu, iintlobo zazo ezahlukeneyo, kunye nokusetyenziswa kwazo kumashishini ahlukeneyo.
Ukwandiswa kweevalvu sisixhobo esibalulekileyo esenza kube lula ukusebenzisa nokugcina iivalvu kwiindawo ezinzima ukufikelela kuzo. Ngokusisiseko zandisa isiphatho okanye indlela yokulawula yevalvu, zivumela ukuba isebenze kwaye ilawulwe ikude. Ukwandiswa kweevalvu kudla ngokusetyenziswa apho ivalvu igqunywe phantsi komhlaba, ngasemva kwesiphazamiso, okanye isebenza phantsi kobushushu obuphezulu, uxinzelelo, okanye iimeko eziyingozi.
Uhlobo
Kukho iintlobo ezahlukeneyo zokwandiswa kweevalvu ezithengiswayo namhlanje. Uhlobo oludumileyo lolwandiso lwesiqu sevalvu, olusetyenziswa rhoqo kwiivalvu ezikwimingxuma enzulu okanye ezingcwatywe phantsi komhlaba. EziulwandisoNgokwesiqhelo zenziwe ngezinto ezihlala ixesha elide ezifana nentsimbi engagqwaliyo okanye ithusi ukuze zimelane neemeko ezinzima zokusingqongileyo. Zibonelela ngonxibelelwano oluqinileyo phakathi kwesiqu sevalvu kunye nesiphatho sokusebenza esingaphezulu komhlaba ukuze kube lula ukuyisebenzisa nokulawula.
Olunye uhlobo lolwandiso lwevalvu lulwandiso lwevili lesandla. Olu lwandiso lusetyenziselwa ukwandisa ukufikelela okanye ukuphakama kwevili lesandla, okuvumela ukusebenza kakuhle kweevalvu ezikwiindawo ezixineneyo okanye ezikude kakhulu. Zisetyenziswa kakhulu kumashishini afana nokucoca amanzi, ukuvelisa umbane kunye nokucubungula iikhemikhali, apho ezi valve zinokufakwa kwiindawo ezingafikelelekiyo.
Ukongeza kwizandiso ze-stem kunye ne-handwheel, kukwakho nezandiso ze-lever, ezifanelekileyo kwiivalvu ezifuna ukujikeleza rhoqo okanye ezikwiindawo ezinobungozi. Izandiso ze-lever zibonelela ngengalo ye-lever eyongeziweyo yokwandisa i-lever kunye nokusebenza okubushelelezi. Zingafakwa kwaye zisuswe ngokukhawuleza xa zifuneka, nto leyo eyenza zibe sisisombululo esisebenzisekayo kwiinkampani ezahlukeneyo.
Ukusebenzisa
Ulwandiso lweevalvu lusetyenziswa kakhulu kumashishini ahlukeneyo. Umzekelo, kwicandelo leoyile negesi, ulwandiso lweevalvu lusetyenziswa kwiivalvu ezikwiindawo ezikude elunxwemeni okanye elunxwemeni. Olu lwandiso lwenza ukuba abaqhubi bakwazi ukulawula ukuhamba kolwelo okanye iigesi, ukuqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo kwemibhobho okanye izibonelelo zemveliso. Ngokufanayo, kushishino lwamanzi namanzi amdaka, ulwandiso lweevalvu lunceda iivalvu ezifakwe kwiindawo ezingaphantsi komhlaba, kwiindawo ezingenanto okanye ezingaphantsi kwamanzi, okwenza kube lula ukuzigcina nokuzilungisa.
Ukwandiswa kweevalvu kukwasetyenziswa kakhulu kwishishini le-HVAC (ukufudumeza, ukuphefumla kunye ne-air conditioning). Iivalvu zenkqubo ye-HVAC zihlala zikwiindawo ezincinci okanye ezingaqhelekanga, nto leyo eyenza ukusebenza kwazo kube nzima. Ukwandiswa kweevalvu kwenza kube lula le nkqubo ngokwandisa ukufikelela kwesiphatho sevalvu ukuze kube lula ukulungisa nokulawula. Zikwavumela iingcali ukuba zenze ulondolozo oluqhelekileyo ngaphandle kokuphazamisa yonke inkqubo.
Isiphelo
Ngamafutshane, ulwandiso lweevalvu luluncedo kakhulu kumashishini apho iivalvu kunzima ukuzifikelela okanye ukuzisebenzisa. Zenza kube lula ukugcinwa, ukulungiswa kunye nokusebenza kweevalvu kwiindawo ezinzima ukuzifikelela ngokwandisa ukufikelela kwesiphatho sevalvu okanye indlela yokulawula. Iindidi ezahlukeneyo zolwandiso lwesiqu sevalvu, ulwandiso lwe-handwheel kunye nolwandiso lwe-lever ziyafumaneka ukubonelela ngezisombululo ezifanelekileyo kumashishini ahlukeneyo kunye nezicelo. Nokuba kukwioyile negesi, unyango lwamanzi okanye i-HVAC, ulwandiso lweevalvu luqinisekisa ukusebenza kakuhle kunye nobude bexesha leevalvu ezibalulekileyo.
