1. Cacisa injongo yeivalvekwisixhobo okanye isixhobo
Misela iimeko zokusebenza zevalve: ubunjani bendawo esebenzayo, uxinzelelo olusebenzayo, ukushisa okusebenzayo kunye nendlela yokulawula.
2. Khetha ngokuchanekileyo uhlobo lwevalve
Ukhetho oluchanekileyo lohlobo lwevalve luyimfuneko kumyili ukuze abambe ngokupheleleyo yonke inkqubo yokuvelisa kunye neemeko zokusebenza. Xa ukhetha uhlobo lwevalve, umyili kufuneka aqale abambe iimpawu zesakhiwo kunye nokusebenza kwevalve nganye.
3. Ukugqiba ukudibanisa kwevalve
Phakathi kwemidibaniso edityanisiweyo, imidibaniso yeflange, kunye noqhagamshelo oludityanisiweyo lwesiphelo, ezimbini zokuqala zezona zisetyenziswa kakhulu. Iivalvu ezinemisonto ubukhulu becala ziivalvu ezinomlinganiselo ongaphantsi kwama-50mm. Ukuba ububanzi bukhulu kakhulu, ukufakela kunye nokutywinwa kwenxalenye yokudibanisa kuya kuba nzima kakhulu. Iivalve eziphothiweyo zikulungele ukufakela kunye nokuqhaqha, kodwa zinzima kwaye zibiza kakhulu kuneevalve ezinemisonto, ngoko ke zilungele ukudityaniswa kwemibhobho yeedayamitha ezahlukeneyo kunye noxinzelelo. Uxhumo oludibeneyo lufanelekile kwimithwalo enzima kwaye lunokwethenjelwa ngakumbi kunoxhumo lwe-flanged. Nangona kunjalo, kunzima ukudibanisa kunye nokufaka kwakhona i-valve edibeneyo nge-welding, ngoko ke ukusetyenziswa kwayo kunqunyelwe kwiimeko apho ngokuqhelekileyo ikwazi ukuqhuba ngokuthembekileyo ixesha elide, okanye apho iimeko zokusetyenziswa zinzima kwaye ubushushu buphezulu.
4. Ukukhethwa kwezinto zevalvu
Xa ukhetha izinto zegobolondo yevalve, iindawo zangaphakathi kunye nokutywinwa kwendawo, ngaphezu kokuqwalasela iimpawu ezibonakalayo (ubushushu, uxinzelelo) kunye neempawu zeekhemikhali (ukonakala) kwendawo yokusebenza, ukucoceka kwendawo ephakathi (kunye okanye ngaphandle kwamasuntswana aqinileyo) kufuneka nayo ibanjwe. Ukongezelela, kuyimfuneko ukubhekisela kwimimiselo efanelekileyo karhulumente kunye nesebe labasebenzisi. Ukukhethwa okuchanekileyo kunye nokufanelekileyo kwezinto zevalve kunokufumana ubomi benkonzo yezoqoqosho kunye nokusebenza kakuhle kwevalve. Ulandelelwano lwempahla yevalve yomzimba yile: intsimbi yesinyithi-yekhabhoni yentsimbi-engenasici, kunye neseyingi yokutywina ulandelelwano lwezinto ezikhethiweyo yile: irabha-yobhedu-alloy steel-F4.
5. Okunye
Ukongezelela, izinga lokuhamba kunye nenqanaba loxinzelelo lwe-fluid ehamba nge-valve kufuneka kwakhona igqitywe, kwaye i-valve efanelekileyo kufuneka ikhethwe ngokusebenzisa idatha ekhoyo (efana neiikhathalogu imveliso valve, iisampuli zemveliso yevalvu, njl.).
