Uhlobo lwe-valve yokusiza

Ngokusho kwesakhiwo esihlukile, i-valve yokusiza ingahlukaniswa ngezigaba ezimbili: uhlobo olusebenzayo oluqondile kanye nohlobo oluholayo. I-valve yokusiza esebenza ngokuqondile iyi-valve yokukhulula lapho umfutho we-hydraulic womugqa omkhulu kawoyela osebenza ku-spool ulingana ngokuqondile namandla alawula intwasahlobo. Ngokusho kwezinhlobo ezahlukene zesakhiwo sembobo ye-valve kanye nendawo yokulinganisa ingcindezi, izakhiwo ezintathu eziyisisekelo ziyakhiwa. Kungakhathaliseki ukuthi hlobo luni lwesakhiwo, i-valve yokusiza esebenza ngokuqondile yakhiwe izingxenye ezintathu: ingcindezi elawula intwasahlobo nesibambo esilawula ingcindezi, imbobo yokuchichima nendawo yokulinganisa ingcindezi. Ukuqhathanisa phakathi kwe-valve yokusiza esebenza ngokuqondile kanye ne-valve yokusiza ehamba phambili: i-valve yokusiza esebenza ngokuqondile: isakhiwo esilula, ukuzwela okuphezulu, kodwa ukucindezela kuthinteka kakhulu ngokushintsha kokugeleza kokuchichima, ukuphambuka kokulawulwa kwengcindezi kukhulu, akufanelekile ukusebenza ngaphansi kwengcindezi ephezulu futhi enkulu. ukugeleza, okuvame ukusetshenziswa njenge-valve yokuphepha noma ngezikhathi lapho ukunemba kokulawula ingcindezi kungephezulu.

I-valve yokusiza umshayeli: Isiphethu se-valve esiyinhloko sisetshenziswa kakhulu ukunqoba ukungqubuzana kwe-valve core, futhi ukuqina kwentwasahlobo kuncane. Lapho ukuguqulwa kwezinga lokuchichima kubangela ushintsho oluyinhloko lokucindezela kwe-valve entwasahlobo, ukuguqulwa kwamandla entwasahlobo kuncane, ngakho-ke ukuguqulwa kwe-valve yokungena kwe-valve kuncane. Ukunemba okuphezulu kokulawulwa kwamandla kagesi, okusetshenziselwa kabanzi ekucindezelweni okuphezulu, uhlelo olukhulu lokugeleza. I-spool ye-valve yokusiza ibhekene nesenzo sokungqubuzana phakathi nenqubo yokuhamba, futhi isiqondiso sokungqubuzana emahoreni okuvula nawokuvala kwe-valve kuphambene nje, ukuze izici ze-valve yokusiza zihluke lapho ivuliwe. nalapho ivaliwe.
