Umhlangano we-Solenoid valve 211-2092 I-valve ye-Solenoid ye-hydraulic valve

Uyini umehluko phakathi kwe-valve ye-proportional valve ne-solenoid evamile?

I-valve ye-Proportional wuhlobo olusha lwedivayisi yokulawula amanzi. Ku-valve yokucindezela evamile, i-valve yokugeleza kanye ne-valve yokuqondisa, i-electromagnetic proportional isetshenziswa esikhundleni sengxenye yokulawula yasekuqaleni, ngokusho kukagesi wokufakwayo.
Isignali yegesi ilawula ngokuqhubekayo nangokulinganayo ingcindezi, ukugeleza, noma isiqondiso somfudlana kawoyela ukude. Ama-valve alinganiselayo ngokuvamile asebenza ngokunxeshezelwa kwengcindezi, futhi ingcindezi yokuphumayo nezinga lokugeleza kungase kungathintwa izinguquko zomthwalo.

I-1, i-valve evamile ayilingani nokulawulwa kwesinyathelo esiqhubekayo, iyi-valve ehlanzekile yohlobo olulodwa lwesenzo, isiqondiso sokuvula i-valve, inani lokuvula noma amandla okusetha kwentwasahlobo aqinisekile.
Awukwazi ukushintshwa ngokuya ngezimo zangempela.

2, i-valve yokulingana ilingana nokulawulwa kwesinyathelo esiqhubekayo, ngokusho kwesimo sangempela sishintsha olwazini oluqoqwe ekuqondisweni kwesinxephezelo esizenzakalelayo esiqondiwe, indlela yokuvula i-valve, inani lokuvula nomai-spring set force ilandelwa, ukuze kuzuzwe uchungechunge lwezinguquko eziqhubekayo ezilawulwayo ekuhambeni. Ukulawula ukugeleza kwe-valve kungahlukaniswa ngezinhlobo ezimbili: eyodwa iwukulawula ukushintsha: noma evulekile ngokugcwele, noma ivalwe ngokugcwele, ukugeleza kungaba, noma kuncane, akukho isimo esimaphakathi, njenge-electromagnetic evamile ngokusebenzisa i-valve, i-electromagnetic reversing valve, i-electro-hydraulic reversing. i-valve. Okunye ukulawulwa okuqhubekayo: imbobo ye-valve ingavulwa ngokwesidingo sanoma yiliphi izinga lokuvula, ngaleyo ndlela ilawule ubukhulu bokugeleza, ama-valve anjalo anokulawula okubhaliwe, njengama-throttle valve, kodwa futhi alawulwa nge-elekthronikhi, njenge-proportional. ama-valve, ama-servo valves.

I-valve ye-solenoid elinganayo

Isebenza kanjani:

Zonke izingxenye zevalvu ye-solenoid ziyikhoyili kagesi ngokwengxenye kagesi, okungukuthi, i-inductor. Lapho i-inductor inikezwa isignali kagesi, inkambu ye-electromagnetic ekhiqizwe i-current izokwenza umgogodla we-valve unyakaze futhi ibone ukuguqulwa kwamapharamitha alawulwayo.
Ukuhlonza ikhwalithi:
Ikhoyili ngayinye ye-electromagnetic inenani eligxilile lokumelana no-R, kodwa le R ayikwazi ukuba "0" noma "∞", uma u-R= "0" ebonisa isifunda esifushane sangaphakathi: lapho u-R= "∞" ebonisa isekethe evuliwe yangaphakathi; nge
Ukumelana kwekhoyili endlini akukwazi ukuba "0". Uma izimo ezingenhla zingahlangatshezwana nazo futhi i-valve ye-solenoid ingasebenzi, kungase kube ukuthi okokufaka kwesignali akulungile noma umgogodla we-valve ubambekile.
