     Isimiso sokusebenza se-valve yokugeleza

I-valve yokugeleza iwuhlobo lwemishini elawulayo yokulawula ukugeleza koketshezi, isimiso sayo sokusebenza ukulungisa usayizi wokugeleza ngokushintsha indawo yokugeleza kwepayipi.I-valve yokugeleza isetshenziswa kakhulu ohlelweni lokudlulisa amanzi futhi idlala indima ebaluleke kakhulu.Izingxenye eziyinhloko ze-valve yokugeleza zihlanganisa umzimba we-valve, izakhi ezilawulayo (ezifana ne-spool, i-valve disc, njll.) kanye ne-actuator (efana nozibuthe kagesi, i-hydraulic motor, njll.).Izinhlobo ezahlukene zama-valve okugeleza nazo zihlukile ngesakhiwo, kodwa isimiso sabo sokusebenza siyafana.
Isimiso sokusebenza se-valve yokugeleza singamane sihlukaniswe zibe izinqubo ezimbili: ukuguqulwa kwesimo sesici esilawulayo kanye nokunyakaza kwe-spool/disc.

Okokuqala, lapho uketshezi ludlula emzimbeni we-valve yokugeleza, luhlangana nesici esilawulayo.Lezi zakhi zokulawula zinendawo ethile emzimbeni we-valve, futhi indawo yokugeleza ye-liquid ingashintshwa ngokulungisa indawo yabo.Ngale ndlela, ukugeleza koketshezi kungalawulwa.Izakhi zokulawula ezijwayelekile ziyi-spool ne-disc.

Okwesibili, i-valve yokugeleza nayo ine-spool noma i-disc mechanism, ukunyakaza kwayo kushintsha ukugeleza koketshezi emzimbeni we-valve.Isibonelo, uma i-electromagnetic icushiwe, i-spool izohanjiswa phezulu noma phansi ngamandla kazibuthe.Lesi senzo sishintsha indawo yento elawulayo, yona elawula ukugeleza koketshezi.Ngokufanayo, lapho i-hydraulic motor ishayela i-valve disc ukuze ijikeleze, izophinde iguqule indawo yokugeleza koketshezi, ngaleyo ndlela ilawule izinga lokugeleza.
