Tinyatselo tekucaphela tekusebenta kwevalve.

Inchubo yekusebenta kwevalve iphindze ibe yinchubo yekuhlola nekuphatsa levalve. Nobe kunjalo, letintfo letilandzelako kufanele tinakwe nawusebentisa le-valve.

1Ivalve lesetulu yekushisa. Uma lizinga lekushisa likhuphuka ngetulu kwa 200°C, lamabhawudi ayashiswa futsi akhule, lokulula kwenta kutsi sivalo se valve sikhululeke. Ngalesikhatsi, emabhawudi adzinga “kuciniswa ngekushisa”, futsi akukalungi kwenta lokushisa-kuciniswa endzaweni levaliwe ngalokuphelele ye valve, kwentela kugwema kutsi sicu se valve singafi futsi kube matima kusivula ngemuva kwesikhatsi.

2Ngesikhatsi lapho khona lizinga lekushisa lingaphansi kwa 0°C, naka kuvula ipulaki yesihlalo sevalve yemavalvu lamisa umfutfo nemanti kususa emanti lahlanganisiwe kanye nemanti lanqwabelene, kwentela kugwema kubandza kanye nekudzabuka kwevalve. Naka kulondvolotwa kwekushisa kwemavalvu langakhoni kucedza kugcwala kwemanti kanye nemavalvu lasebenta ngesikhatsi lesitsite.

Lendlala yekupakisha akukafaneli icindetelwe kakhulu, futsi kusebenta lokugucugucukako kwesicu sevalve kufanele kuncobe (akukalungi kucabanga kutsi uma indlala yekupakisha icinile, kuncono, kutawusheshisa kugcoka kwesicu sevalve futsi kukhulise i-torque yekusebenta). Ngaphansi kwesimo sekungabi khona kwetindlela tekuvikela, lokupakisha akukwati kushintjwa noma kungetwe ngaphansi kwekucindzeteleka.

4Ngesikhatsi sekusebenta, tintfo letingakavami letitfolakala ngekulalela, kunuka, kubona, kutsinta, njll kufanele tihlaziywe kahle ngetizatfu, futsi leto letingetisombululo tabo kufanele tisuswe ngesikhatsi;

Umsebentisi kumele abe nencwadzi lekhetsekile yekubhala noma incwadzi yekubhala, futsi anake kubhala phansi kusebenta kwemavalvu lehlukahlukene, ikakhulukati lamanye emavalvu labalulekile, emavalvu lashisa kakhulu kanye nekucindzeteleka lokusetulu kanye nemavalvu lakhetsekile, kufaka ekhatsi tintfo tabo tekudlulisela. Kufanele kuphawulwe kwehluleka, ukwelashwa, tincenye esikhundleni, njll, letintfo tibalulekile ku-opharetha ngokwayo, tisebenti tekulungisa kanye nemkhiciti. Sungula ilogi lekhetsekile lenemisebenti lecacile, lezuzisako ekuciniseni kulawula.
