Iindlela zokukhetha iivalve
I-1, i-valve yokutshekisha (i-aetv yendlela enye): ngokuqhelekileyo isetyenziswa kwimidiya ecocekileyo, kungekhona ukuba iqulethe iinqununu eziqinileyo kunye ne-viscosity ye-medium.
I-2, ilandela ivalve ephantsi yoxinzelelo lwe-DN50mm (i-aetv yendlela enye) :, kufuneka isebenzise ivalve yebhabhathane, ivalve yokukhangela kunye nevalve yokukhangela ethe nkqo ye-diaphragm; Kwi-DN enkulu kune-200mm, ngaphantsi kwe-1200mm yevalve yokukhangela uxinzelelo oluphantsi, ivalve engabuyiyo kufuneka ikhethwe kwi-spherical yokunxiba; kwi-DN enkulu kuno-50mm, ngaphantsi kwe-2000mm yevalve yokukhangela uxinzelelo oluphantsi, ivalve yebhabhathane kunye ne-diaphragm kufuneka isebenzise iivalvu zokujonga.
I-3, ivalve ye-diaphragm ilungele ukuvelisa ihamile yamanzi kumbhobho, inwebu inokupheliswa okuphakathi komlambo iveliswa xa isando samanzi, kodwa ngeqondo lobushushu kunye nemida yoxinzelelo, ngokubanzi kubushushu begumbi kumbhobho woxinzelelo oluphantsi.
