I-hydraulic balance valve Excavator hydraulic cylinder spool PBHB-LCN

Ama-valve e-hydraulic ahlukaniswe ikakhulukazi izigaba ezine: nge-valve, i-valve yokuphepha, i-valve yokulawula kanye ne-valve yokuqondisa. Okokuqala, ake siqonde i-valve ngokusebenzisa. I-valve edlulayo (eyaziwa nangokuthi i-valve evamile noma i-valve yokuvala) iyi-valve evame kakhulu ohlelweni lwe-hydraulic, esetshenziselwa ukulawula ukuphuma koketshezi futhi inesibopho sokuvula nokuvala uketshezi ngaphakathi. uhlelo lwe-hydraulic. Isici esiyinhloko se-valve ye- through yisakhiwo esilula, esisebenziseka kalula, esisetshenziswa kabanzi ekukhiqizeni izimboni nezolimo zezinhlelo ze-hydraulic.

Okwesibili, ake sibheke ama-valve okuphepha. I-valve yokuphepha (eyaziwa nangokuthi i-valve yokukhulula noma i-valve yokulayishwa ngokweqile) iyingxenye ebalulekile ohlelweni lwe-hydraulic ukuvikela ukuphepha kwezinto zokusebenza nabasebenzi. Lapho ingcindezi ohlelweni lwe-hydraulic idlula inani elibekiwe, i-valve yokuphepha izovuleka ngokushesha, ukuze uketshezi oluningi lukhishwe nge-port echichimayo, ngaleyo ndlela ivikele uhlelo nemishini emonakalweni. I-valve yokuphepha ibonakala ngokulawulwa kwengcindezi okuzenzakalelayo nokuthembeka okuphezulu, okudlala indima ebalulekile ohlelweni lwe-hydraulic.

Uhlobo lwesithathu lwe-hydraulic valve yi-valve yokulawula. I-valve yokulawula isetshenziselwa ukulawula ingcindezi, ukugeleza kanye nesiqondiso soketshezi ohlelweni lwe-hydraulic, ukuze kuzuzwe ukulawula okunembile kohlelo. Izici eziyinhloko ze-valve yokulawula ziyisakhiwo esiyinkimbinkimbi nemisebenzi ehlukahlukene, esetshenziswa kabanzi ohlelweni lokulawula ukukhiqizwa kwezimboni. Kunezinhlobo eziningi zama-valve okulawula, ama-valve okusiza avamile, ama-valve okulawula isiqondiso, ama-valve okulawula ukugeleza nokunye. I-valve ngayinye yokulawula inezici zayo kanye nezicelo, futhi ingakhethwa ngokuvumelana nezidingo zangempela.
