Kukhona futhi ama-valve ahlehlayo ezitshalweni zokuxuba i-asphalt, ngokuvamile ezingabangeli izinkinga, ngakho angizange ngiqonde ngokucophelela izixazululo zayo ngaphambili. Kodwa ekusetshenzisweni kwangempela, ngihlangabezane nalolu hlobo lokwehluleka. Kufanele ngibhekane kanjani nakho?

Ukwehluleka kwe-valve ehlehlayo esitshalweni sokuxuba i-asphalt akuyona inkimbinkimbi, okungukuthi, ukuguqulwa okungazelelwe, ukuvuza kwegesi, ukwehluleka kwe-valve yomshayeli we-electromagnetic, njll. Izimbangela ezihambisanayo nezisombululo zihlukile. Ngokwenzeka kokuhlehliswa kungakabi yisikhathi kwe-valve ehlehlayo, ngokuvamile kubangelwa ukugcotshwa okubi, iziphethu ezibambekile noma ezilimele, uwoyela noma ukungcola okubhajwe engxenyeni eshelelayo, njll. Ngalokhu, kuyadingeka ukuhlola isimo sedivayisi yenkungu kawoyela. kanye ne-viscosity yamafutha okugcoba. Uma kunesidingo, amafutha okugcoba noma ezinye izingxenye zingashintshwa.
Ngemuva kokusetshenziswa isikhathi eside, i-valve ehlehlayo ijwayele ukugqokwa yiringi ye-valve core seal, ukulimala kwesiqu se-valve nesihlalo se-valve, okuholela ekuvuzeni kwegesi ku-valve. Ngalesi sikhathi, indandatho yophawu, isiqu se-valve nesihlalo se-valve kufanele kushintshwe, noma i-valve ehlehlayo kufanele ishintshwe ngokuqondile. Ukuze unciphise izinga lokuhluleka kwe-asphalt mixer, ukugcinwa kufanele kuqiniswe ngezikhathi ezijwayelekile.
