Isilawuli somshayeli we-CBBC-LAN Ivalvu enkulu yokulinganisa ukugeleza

     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.

indima ye-valve yokusiza
I-1, umphumela wokuchichima kwengcindezi eqhubekayo: ohlelweni lokulawula i-quantitative pump throttling, iphampu yobuningi inikeza ukugeleza okuqhubekayo. Lapho ingcindezi yesistimu ikhuphuka, isidingo sokugeleza siyehla. lokhu
Lapho kuvulwa i-valve yokuphepha, ukugeleza okweqile kubuyiselwa ethangini ukuze kuqinisekiswe ukuthi ukucindezela kokungena kwe-valve yokuphepha, okungukuthi, ukucindezela kokuphuma kwepompo, kuhlala njalo (imbobo ye-valve ivamise ukuba nokucindezela.
Vula amagagasi ngamandla).
I-2, umphumela wokulawula ingcindezi: i-valve yokusiza ixhunywe ochungechungeni kumjikelezo wokubuyisela uwoyela, i-valve yokukhulula ikhiqiza ukucindezela emuva, futhi ukuzinza kwezingxenye ezihambayo kuyanda.
I-3, umsebenzi wokuthulula isistimu: imbobo yokulawula kude ye-valve yokukhulula ixhunywe ku-solenoid valve ngokugeleza okuncane okuchichimayo. Uma i-electromagnetic inikwa amandla, imbobo yesilawuli kude sevalvu yokuphepha kanye nethangi likaphethiloli kuxhunyiwe
Ixhunyiwe, kulokhu iphampu ye-hydraulic ithulula. I-valve yokuphepha isetshenziswa njenge-valve yokuphepha.
I-4, ukuvikelwa kokuphepha: lapho uhlelo lusebenza ngokujwayelekile, i-valve ivaliwe. Ukuchichima kuphela uma umthwalo weqa umkhawulo oshiwo (ingcindezi yesistimu idlula ingcindezi ebekiwe)
I-valve izovulwa, nokuvikelwa kokulayisha ngokweqile, ukuze ingcindezi yesistimu ingasakhushulwa (imvamisa ingcindezi ebekiwe ye-valve yokuphepha ingu-10% -20 ingcindezi yesistimu ephakeme kunengcindezi ephezulu yokusebenza)
Force).
