Ukufakwa kweValve yokuHlola
Ivalve yokukhangela kufuneka ifakwe kwindawo yokuphuma yempompo kunye naphambi kwevalve yokulawula yokuphuma ukuze igcinwe.Ngokuqhelekileyo, i-outlet yokuqala yempompo kukudibaniswa okuthambileyo (i-absorber eyethusayo), ilandelwa yivalve yokukhangela, kunye nevalve yebhloko (njengevalve yebhabhathane, ivalve yesango, ivalve yokumisa, njl. njl.).
1. Faka ivalve yokutshekisha kuqala uze emva koko ufake ivalve yesango okanye ivalve yebhabhathane
Izibonelelo: inokukhusela i-valve yokutshekisha, ngakumbi kwiimpompo ezihambelanayo.Xa impompo enye ingaqali kwaye enye impompo iqala, amandla empembelelo athwalwa yivalve yesango okanye ivalve butterfly.
Izinto ezingeloncedo: ngubani oza kukhusela ivalve yesango okanye ivalve yokukhangela?Kwakukho imeko yokuba ipleyiti yevalve yevalve yebhabhathane yaphukile.
2. Fakela ivalve yesango okanye ivalve yebhabhathane phambi kokukhangela ivalve
Izinto eziluncedo: inokukhusela ivalve yebhabhathane okanye ivalve yesango, kwaye amandla empembelelo athwalwa yivalve yokutshekisha
Ukungalungi: ngubani oya kukhusela ivalve yokutshekisha?Ivalve yokukhangela ivuliwe kwaye ivalwe ngumahluko woxinzelelo.Ukuba uxinzelelo lwentloko luphezulu, luya kuvalwa kwaye uxinzelelo lwempompo luya kuvulwa.Ukuba ukuhamba okusetyenzisiweyo akuzinzile, i-valve yokutshekisha iya kuvulwa kwaye ivalwe ngokuphindaphindiweyo, eya kuchaphazela ubomi benkonzo ye-valve yokukhangela.
