Kukho kwakhona i-valve yokubuyisela umva kwisityalo sokuxuba i-asphalt, ngokubanzi engabangeli iingxaki, ngoko andizange ndiqonde izisombululo zayo ngokweenkcukacha ngaphambili. Kodwa ekusebenziseni okwenyani, siye sadibana nolu hlobo lokusilela. Sifanele sijongane njani nayo?
Ukungaphumeleli kwe-valve yokuguqula izityalo zokuxuba i-asphalt ayinzima, oko kukuthi, ukubuyisela umva akukafiki ngexesha, ukuvuza kwegesi, ukungaphumeleli kwe-valve ye-electromagnetic pilot valve, njl. Izizathu ezihambelanayo kunye nezisombululo zihluke ngokuqinisekileyo. Ukuze ivalve yokubuyisela ingatshintshi isalathiso ngexesha, ngokuqhelekileyo ibangelwa kukuthanjiswa okungahambi kakuhle, umthombo ubambekile okanye wonakaliswe, ukungcola kweoli okanye ukungcola kubambeke kwindawo yokutyibilika, njl. i-lubricator kunye nomgangatho we-oyile yokuthambisa. I-Viscosity, ukuba kuyimfuneko, i-lubricant okanye ezinye iindawo zingatshintshwa.
Emva kokusetyenziswa kwexesha elide, ivalve ebuyela umva ithanda ukunxitywa kwiringi yevalve engundoqo yokutywina, ukonakala kwesikhondo sevalve kunye nesitulo sevalvu, okukhokelela ekuvuzeni kwegesi kwivalve. Ngeli xesha, umsesane wokutywina, isiqu sevalve kunye nesihlalo sevalvu kufuneka itshintshwe, okanye ivalve yokubuyisela umva kufuneka itshintshwe ngokuthe ngqo. Ukuze kuncitshiswe izinga lokungaphumeleli kwe-asphalt mixers, ukugcinwa kufuneka kuqiniswe yonke imihla.
