I-valve yokusiza ingcindezi esebenza nge-Hydraulic eqondile YF06-09

I-valve yokuchichima kanye ne-valve yokuphepha amagama amabili ahlukene lapho i-valve echichimayo idlala indima yokuqiniswa kwengcindezi echichimayo kanye nokuvikela okukhawulela ingcindezi. Uma i-valve echichimayo idlala indima yokuqiniswa kwengcindezi echichimayo, ibizwa ngokuthi i-overflow valve, futhi uma idlala indima yokuvikela ukukhawulela ingcindezi, ibizwa ngokuthi i-valve yokuphepha. Indlela yokuhlukanisa? Kuhlelo lokulawula isivinini sephampu ehlala-displacement, ngenxa yokuthi ukugeleza kukawoyela kwepompo kuhlala njalo, lapho ukugeleza kulawulwa yi-throttle valve (inqubo yokulawula isivinini se-throttle), ukugeleza ngokweqile kuphuma ku-valve yokuchichima futhi kubuyela ithangi lamafutha. Ngalesi sikhathi, i-valve yokuchichima idlala indima yokulawula ingcindezi yesistimu ngakolunye uhlangothi, futhi idlala indima yokuqiniswa kwengcindezi yokuchichima lapho i-throttle valve ilawula ukugeleza, futhi i-valve yokuchichima ivuliwe (evame ukuvuleka) kulolu hlobo. yenqubo yomsebenzi. Kuhlelo lwephampu oluguquguqukayo, ukulungiswa kwesivinini kubonakala ngokushintsha izinga lokugeleza kwepompo. Kule nqubo, akukho ukugeleza okweqile okuvela ku-valve yokuchichima, futhi i-valve yokuchichima ayivuli (ngokuvamile ivaliwe). Kuphela lapho ingcindezi yomthwalo ifinyelela noma idlula ingcindezi ebekiwe ye-valve yokusiza, i-valve yokusiza iyavula futhi igcwale, ukuze ingcindezi yesistimu ingaphinde iphakame, okunciphisa ukucindezela okukhulu kwesistimu futhi ivikele uhlelo lwe-hydraulic. Kulesi simo, i-valve yokusiza ibizwa ngokuthi i-valve yokuphepha. Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi kumjikelezo wokulawula isivinini, uma kuwuhlelo oluqhubekayo lokuphakela uwoyela wepompo, i-valve yokuchichima idlala indima yokuchichima nokuqiniswa kwengcindezi, futhi uma kuwuhlelo oluguquguqukayo lokuphakela uwoyela wepompo, I-valve echichimayo idlala indima yokuvikela ukucindezela ingcindezi futhi isetshenziswa njenge-valve yokuphepha.
