Isakhiwo esiyisisekelo kanye nesisekelo sokusebenza se-valve yosizo ohlelweni lokudluliselwa kwe-hydraulic, i-hydraulic valve elawula izinga lokucindezela kukawoyela libizwa ngokuthi yi-Valive Control valve, okubizwa ngokuthi yi-valve yengcindezi. LOKHO Ama-valves afana ngayo ukuthi asebenza ngomgomo wokuthi ingcindezi kamanzi esebenza e-spool kwathi amandla entwasahlobo ayalingana. Okokuqala, ukwakheka okuyisisekelo kanye nomgomo wokusebenza we-valve yokusiza

Umsebenzi oyinhloko we-valve yokusiza ukuhlinzeka ngokucindezela okungapheli noma ukuvikelwa kokuphepha kohlelo lwe-hydraulic.

(A) Indima Nezidingo Zokusebenza ze-valve yosizo

1. Iqhaza le-valve yokusiza ohlelweni lwe-hydraulic ukuze lugcine ingcindezi engapheli ukusetshenziswa kwe-valve yokusiza. Imvamisa isetshenziswa ezinhlelweni zokulawula ijubane, futhi ama-valve alawulwa yi-flow asetshenziselwa ukulungisa ukugeleza ohlelweni, futhi agcine ingcindezi yohlelo ngokuyisisekelo njalo. Ama-valves wokusiza wokuvikela ngokweqile ngokuvamile kubizwa ngokuthi ama-valves okuphepha.

2. Uhlelo lwe-hydraulic lwezidingo zokusebenza kwe-valve valve

(1) Ukunemba okuphezulu kwengcindezelo

(2) Ukuzwela okuphezulu

(3) Umsebenzi kufanele ube bushelelezi futhi ngaphandle kokudlidliza nomsindo

(4) Lapho i-valve ivaliwe, uphawu kufanele lube luhle futhi ukuvuza kufanele kube kuncane.

(2) isakhiwo kanye nokwenza umgomo we-valve yokusiza

I-valve yokusiza esetshenziswa ngokujwayelekile ngokuya ngesakhiwo sayo kanye nemodi yesisekelo yesenzo ingancishiswa ukuqondisa uhlobo lwe-Worting kanye nohlobo lwe-Pilot.

1. I-Value Surding Suimung Suimung Surve the Valve eqondile yokusiza uncike emafutheni wengcindezelo ohlelweni ukuze asebenze ngokuqondile e-spool futhi alinganise amandla entwasahlobo ukulawula isenzo sokuvula nokuvalwa kwesenzo se-spool kanye nokuvala. I-valve yokusiza isebenzisa ingcindezi elawulwayo njengesiginali yokushintsha inani lokucindezelwa kwentwasahlobo, ngaleyo ndlela iguqule indawo yokugeleza ethekwini le-valve kanye nesilinganiso sokugeleza okuchichimayo kohlelo lokuthola inhloso yengcindezi engapheli. Lapho kukhuphuka ingcindezi yohlelo, i-spool ikhuphuka, indawo yokugeleza kwe-valve port inyuka, isilinganiso esichichimayo siyanda, futhi ingcindezi yohlelo iyancipha. Umphumela wokuphendula ongemuhle owakhiwa ibhalansi nokuhamba kwe-spool ngaphakathi kwe-valve yokusiza yisenzo esiyisisekelo sesenzo saso sokucindezela njalo, futhi futhi singumgomo oyisisekelo wokusebenza kwama-valves aqhubekayo.
