Qhov hluav taws xob fais fab feem ntau yog txuas nrog lub tshuab fais fab thiab lub valve, thiab muab ntsia ua ib lub tshuab fais fab. Lub tshuab fais fab siv hluav taws xob los ua hluav taws xob tig fais fab rau tsav lub valve kom paub cov kev hloov thiab tswj kev ua haujlwm ntawm lub valve. Xws li ua tiav qhov kev hloov lossis tswj lub hom phiaj ntawm cov raj xa dej nruab nrab.
Tus tsav ntawm lub tshuab fais fab feem ntau yog lub cav, thiab qhov qhib los yog kaw qhov kev txiav txim yuav tsum tau siv sij hawm kom simulate, thiab hloov kho. Sib piv nrog qhov ntsuas voltage poob siab. Lub plab solenoid yog qhib thiab yoojyim kaw, feem ntau siv me me thiab siab me me, qhov twg yuav tsum muaj qhov hloov zaus; qhov hluav taws xob valve yog ntxig. Qhov qhib ntawm qhov hluav taws xob valve tuaj yeem tswj tau. Lub xeev tau qhib, raug kaw, ib nrab qhib thiab ib nrab kaw, uas tswj tau qhov khiav ntawm qhov nruab nrab hauv qhov kav dej thiab cov solenoid valve tsis tuaj yeem ua raws li txoj cai no.
Peb-kab hluav taws xob valve muaj peb kab ntawm F / R / N, F sawv kev rau pem hauv ntej (los yog qhib nkaus) kev tswj kab, R sawv kev rov qab ua haujlwm (los yog kaw tes) kev tswj kab, thiab N sawv rau kab hauv av. Lub voj voos solenoid yog hom fais fab kis; cov hlau nplaum tsim los ntawm lub tshuab electromagnetic yog siv los rub lub valve core, yog li hloov qhov qhib thiab kaw ntawm lub cev lub cev, lub coil yog de-energized, thiab cov tub ntxhais valve rov qab los ntawm lub siab ntawm lub caij nplooj ntoos hlav.
