Kukhona futhi i-valve ehlehlayo esitshalweni sokuxuba i-asphalt, ngokuvamile engabangeli izinkinga, ngakho-ke angizange ngiqonde izixazululo zayo ngokuningiliziwe ngaphambili. Kodwa ekusetshenzisweni kwangempela, sihlangabezane nalolu hlobo lokwehluleka. Kufanele sibhekane kanjani nakho?
Ukwehluleka kwe-valve yokuhlehla yezitshalo zokuxuba i-asphalt akuyona inkimbinkimbi, okungukuthi, ukubuyisela emuva akukafiki ngesikhathi, ukuvuza kwegesi, ukwehluleka kwe-valve yomshayeli we-electromagnetic, njll. Izimbangela ezihambisanayo nezixazululo zihlukile. Ukuze i-valve ehlehlayo ingashintshi isiqondiso ngesikhathi, ngokuvamile kubangelwa ukugcotshwa okungalungile, isiphethu sibambekile noma sonakaliswe, ukungcola kwamafutha noma ukungcola kubambeka engxenyeni eshelelayo, njll. Ngalokhu, kuyadingeka ukuhlola isimo i-lubricator kanye nekhwalithi yamafutha okugcoba. I-viscosity, uma kunesidingo, i-lubricant noma ezinye izingxenye zingashintshwa.
Ngemuva kokusetshenziswa isikhathi eside, i-valve ehlehlayo ijwayele ukugqokwa iringi yokuvala i-valve core, ukulimala kwesiqu se-valve nesihlalo se-valve, okuholela ekuvuzeni kwegesi ku-valve. Ngalesi sikhathi, indandatho yokuvala, isiqu se-valve kanye nesihlalo se-valve kufanele kushintshwe, noma i-valve ehlehlayo kufanele ishintshwe ngokuqondile. Ukuze unciphise izinga lokuhluleka kwezixube ze-asphalt, ukugcinwa kufanele kuqiniswe nsuku zonke.
