I-valve yensimbi engagqwali yensimbi ephonswe
Incazelo yomkhiqizo
1.I-valve isetshenziselwa ukuvula nokuvala ipayipi, ukulawula indlela yokugeleza, ukulungisa nokulawula amapharamitha okudlulisa (izinga lokushisa, ingcindezi kanye nokugeleza) kwezesekeli zepayipi. Ngokusho komsebenzi wayo, ingahlukaniswa ibe yi-valve yokuvala, i-valve yokuhlola, i-valve yokulawula njalo njalo.
2.Ivalvu iyingxenye yokulawula yesistimu yokulethwa koketshezi, enemisebenzi yokusika, yokulawula, yokuguqula, yokuvimbela ugesi ophikisanayo, yokulawula ukucindezela, yokunciphisa noma yokunciphisa umfutho wegazi. Amavalvu asetshenziswa ezinhlelweni zokulawula uketshezi asukela kumavalvu alula kakhulu kuya ezinhlelweni zokulawula ezizenzakalelayo eziyinkimbinkimbi kakhulu ezisetshenziswa ezinhlobonhlobo eziningi zezinhlobo kanye nemininingwane.
Ukusetshenziswa komkhiqizo
1.Ivalvu yokuvala: Lolu hlobo lwevalvu luvulekile futhi luvaliwe. Uma lumi endaweni yokungena kanye nendawo yokukhipha amanzi ebandayo kanye nemithombo yokushisa, indawo yokungena kanye nendawo yokukhipha imishini, imigqa yamagatsha epayipi (kufaka phakathi i-riser), ingasetshenziswa futhi njengevalvu yokukhipha amanzi nomoya. Amavalvu okuvala avamile afaka ivalvu yesango, ivalvu yeglobe, ivalvu yebhola kanye nevalvu yebhabhathane.
2.I-valve yokuhlola: Lolu hlobo lwe-valve lusetshenziselwa ukuvimbela ukugeleza emuva kwe-medium, ukusetshenziswa kwamandla e-kinetic oketshezi ukuvula, ukugeleza okuphambene kuvalwe ngokuzenzakalelayo. Ukuma endaweni yokuphuma kwepompo, indawo yokuphuma ebambekayo nakwezinye izindawo akuvumeli ukugeleza okuphambene koketshezi.
3.Ivalvu yokulawula: ivalvu yokulawula ingashintsha i-spool stroke ngokuya ngesiqondiso nosayizi wesignali, ukuze kufezwe injongo yokulawula ukugeleza kwevalvu. Ivalvu yokulawula iphula ivalvu yokulawula kanye nevalvu yokulawula ezenzakalelayo, kanti ivalvu yokulawula esetshenziswa ngesandla noma ezenzakalelayo ihlukaniswe ngezinhlobo eziningi, ukusebenza kwayo kokulawula nakho kuhlukile.
