¢ Uvavanyo lwamandla evalve yokhuseleko luyafana nolwezinye iivalvu. Xa uvavanya inxalenye engezantsi yomzimba we-valve, uxinzelelo lungeniswa ukusuka kwi-I = ndiyaphela, kwaye indawo yokutywina ivaliwe; Xa uvavanya inxalenye ephezulu yomzimba we-valve kunye nesimbozo se-valve, uxinzelelo luyaziswa ukusuka ekupheleni kwe-El, kwaye ezinye iziphelo zivaliwe. Umzimba wevalvu kunye nekhava zifanelekile ukuba akukho kuvuza ngexesha elichaziweyo.
¢Ú Uvavanyo lokutywina kunye novavanyo loxinzelelo oluthe gqolo, ukusetyenziswa ngokubanzi kwesiphakathi yile: ivalve yokhuseleko lomphunga enomphunga ogcweleyo njengendawo yovavanyo; Ivalve yeammonia okanye ezinye iigesi zisebenzisa umoya njengendlela yokuvavanya; Iivalvu zamanzi kunye nolunye ulwelo olungadlekiyo zisebenzisa amanzi njengendawo yovavanyo. Kwezinye iivalvu zokhuseleko ezibalulekileyo, initrogen idla ngokusetyenziswa njengendawo yovavanyo.
Uvavanyo lokutywinwa luya kuqhutywa ngexabiso eliphantsi loxinzelelo njengoxinzelelo lovavanyo, kwaye inani lamaxesha aliyi kuba ngaphantsi kwesibini, kwaye lifanelekile ukuba akukho kuvuza ngexesha elichaziweyo. Kukho iindlela ezimbini zokujonga ukuvuza: enye kukutywina amakhonkco evalve yokhuseleko, uncamathisele isitywina sephepha elincinci kwi-El flange ngebhotela, ukukhutshwa kwephepha elincinci kukuvuza, kwaye enye ifanelekile; Okwesibini, sebenzisa ibhotolo ukutywina ipleyiti ebhityileyo yeplastiki okanye ezinye iipleyiti kwindawo engezantsi yeflange yokuphuma, gcwalisa amanzi ukutywina idiski yevalve, kwaye ujonge ukuba amanzi awabhobhozi njengoko kufanelekile. Inani loxinzelelo oluqhubekayo kunye nokuvavanya kwakhona uxinzelelo lwe-valve yokhuseleko aluyi kuba ngaphantsi kwamaxesha angama-3, kwaye lufanelekile ukuba luhlangabezana neemfuno. Jonga i-GB / T 12242 1989 iindlela zokuvavanya ukusebenza kweevalvu zokhuseleko kwiimvavanyo ezahlukeneyo zokusebenza kweevalvu zokhuseleko
