I-valve yokukhulula I-Excavator i-valve yokulawula i-solenoid valve eyinhloko 723-46-48100

I-valve yokukhulula i-valve yokulawula ukucindezela kwe-hydraulic, edlala indima enkulu yokunciphisa ingcindezi njalo, ukulawulwa kwengcindezi, ukuthulula uhlelo nokuvikelwa kokuphepha emishinini ye-hydraulic. Kuhlelo lwe-quantitative pump throttling regulation system, ipompo yokulinganisa inikeza ukugeleza okuqhubekayo, lapho ingcindezi yesistimu ikhuphuka, isidingo sokugeleza sizoncishiswa, ngalesi sikhathi i-valve yokusiza ivuliwe, ukuze ukugeleza ngokweqile kubuyele ethangini, ukuqinisekisa ukuthi ingcindezi yokungena kwe-valve yokusiza, okungukuthi, ingcindezi yokuphuma kwepompo ihlala njalo. I-valve yokusiza ixhunywe ochungechungeni kumjikelezo wamafutha obuyayo, futhi ukuzinza kwezingxenye ezihambayo zokucindezela emuva kwe-valve yokusiza kuyanda. Umsebenzi wokuthulula wesistimu uwukuxhuma i-valve ye-solenoid ngokugeleza okuchichimayo okuncane ochungechungeni endaweni yesilawuli kude sevalvu yokukhulula. Uma i-electromagnetic inikwa amandla, imbobo yesilawuli kude sevalvu yokukhulula idlula ethangini likaphethiloli. Ngalesi sikhathi, iphampu ye-hydraulic iyehliswa futhi i-valve yokusiza isetshenziswa njenge-valve yokukhipha. Umsebenzi wokuvikela ukuphepha, lapho uhlelo lusebenza ngokujwayelekile, i-valve ivaliwe, kuphela lapho umthwalo udlula umkhawulo obekiwe, ukuchichima kuvulwa, futhi ukuvikelwa kokulayisha ngokweqile kwenziwa, ukuze ukucindezela kwesistimu kungasakhushulwa.

Ukusetshenziswa okuyinhloko kwe-valve yokusiza amaphuzu amabili alandelayo:

(1) Ukulawulwa kwengcindezi kanye nomthethonqubo. Uma isetshenziswe kumthombo we-hydraulic owakhiwe ngepompo yomthamo, isetshenziselwa ukulungisa ukucindezela kokuphuma kwepompo ukuze kugcinwe ukucindezela njalo.

(2) Nciphisa ingcindezi. Uma isetshenziswa njenge-valve yokuphepha, lapho uhlelo lusebenza ngokujwayelekile, i-valve yokusiza isesimweni esivaliwe, futhi iqala ukuchichima kuphela lapho ingcindezi yesistimu inkulu kunokucindezela kwayo okumisiwe, okudlala indima yokuvikela ukulayisha ngokweqile ohlelweni.

Izici ze-valve yokusiza yilezi: i-valve nomthwalo ufuna ukuhambisana, imbobo yokusiza ixhunywe emuva kuthangi likaphethiloli, futhi ukucindezela kokungenisa kuyimpendulo engalungile.

Nakhu ukubuka okusheshayo kwe-valve yokusiza esebenza ngokuqondile:

I-valve yokusiza esebenza ngokuqondile iyi-valve yokukhulula lapho umfutho we-hydraulic womugqa omkhulu kawoyela osebenza ku-spool ulingana ngokuqondile namandla alawula intwasahlobo. Njengoba kuboniswe kuMfanekiso 1, i-valve yokusiza esebenza ngokuqondile yakha izakhiwo ezintathu eziyisisekelo ngenxa yezinhlobo ezihlukene zesakhiwo sembobo ye-valve kanye nendawo yokulinganisa ingcindezi:

Sebenzisa imbobo yokuchichima yohlobo lwe-valve yesilayidi, ukulinganisa kokucindezela kobuso bokuphela;

Imbobo yokuchichima yohlobo lwe-taper valve iyamukelwa, futhi indlela yokulinganisa ingcindezi yobuso bokuphela nayo iyamukelwa.

Indawo yokulinganisa ingcindezi kanye nomphetho we-throttle wembobo yevalvu zombili zisetshenziswa njengama-cones.

Kodwa-ke, kungakhathaliseki ukuthi hlobo luni lwesakhiwo, i-valve yokusiza esebenza ngokuqondile yakhiwe izingxenye ezintathu, ezifana nokulawula ukucindezela kwentwasahlobo nesibambo sokulawula ingcindezi, imbobo ye-valve yokukhulula kanye nendawo yokulinganisa ingcindezi.
