Ivalvu yentsimbi engenasici yentsimbi ephosiweyo
Ingcaciso yeMveliso
1.Ivalvu isetyenziselwa ukuvula nokuvala umbhobho, ukulawula indlela yokuhamba, ukulungisa nokulawula iiparameter zendlela yokudlulisa (ubushushu, uxinzelelo kunye nokuhamba) kwezixhobo zombhobho. Ngokwemisebenzi yayo, inokwahlulwa ibe yivalvu yokuvala, ivalvu yokujonga, ivalvu yokulawula njalo njalo.
2.Ivalvu yinxalenye yolawulo lwenkqubo yokuhambisa ulwelo, ene-cut-off, regulation, diversion, prevent countercurrent, regulation pressure, shunt okanye overflow pressure relief. Iivalvu ezisetyenziswa kwiinkqubo zolawulo lolwelo ziqala kwiivalvu zeglobe ezilula ukuya kwiinkqubo zolawulo oluzenzekelayo ezintsonkothileyo ezisetyenziswa kwiindidi ezahlukeneyo kunye neenkcukacha.
Ukusetyenziswa kwemveliso
1.Ivalvu yokuvala: Olu hlobo lwevalvu luvulekile kwaye luvaliwe. Xa ime kwindawo yokungena kunye nendawo yokuphuma yemithombo ebandayo kunye nobushushu, indawo yokungena kunye nendawo yokuphuma yezixhobo, imigca yesebe lepayipi (kuquka i-riser), ingasetyenziswa njengevalvu yokukhupha amanzi kunye nomoya. Iivalvu zokuvala eziqhelekileyo ziquka ivalvu yesango, ivalvu yeglobe, ivalvu yebhola kunye nevalvu yebhabhathane.
2.Ivalvu yokujonga: Olu hlobo lwevalvu lusetyenziselwa ukuthintela ukubuya kolwelo, ukusetyenziswa kwamandla e-kinetic olwelo ukuvula, ukuhamba okungasemva kuvalwe ngokuzenzekelayo. Ukuma kwindawo yokuphuma kwepompo, kwindawo yokuphuma kwetrap nakwezinye iindawo akuvumeli ukuhamba okungasemva kolwelo.
3.Ivalvu yokulawula: ivalvu yokulawula inokutshintsha i-spool stroke ngokwendlela kunye nobukhulu besignali, ukuze kufezekiswe injongo yokulawula ukuhamba kwevalvu. Ivalvu yokulawula iyawaphula ivalvu yokulawula kunye nevalvu yokulawula ezenzekelayo, kwaye ivalvu yokulawula ngesandla okanye ezenzekelayo yahlulwe kwiintlobo ezininzi, ukusebenza kwayo kokulawula nako kwahlukile.
