Uma kukhulunywa ngama-valves okuphepha, wonke umuntu uyazi ukuthi le yi-valve ebaluleke kakhulu yokuvikela. Isetshenziswa ngokuyisisekelo kuzo zonke izinhlobo zemithambo yengcindezi nezinhlelo zamapayipi. Vele, akulungile ngemishini ye-boiler. Lapho ingcindezi ohlelweni olucindezelwe inkulu kunenani lomkhawulo, i-valve yezokuphepha ingavula ngokuzenzakalelayo futhi ikhiphe ngokweqile emkhathini ukuze iqinisekise ukusebenza okuphephile kwe-boiler futhi kugwemeze izingozi.
Lapho ingcindezi ohlelweni lwe-boiler yehla ngaphakathi kwendawo edingekayo, i-valve yezokuphepha nayo ingavala ngokuzenzakalelayo. Ngakho-ke, uma kunenkinga ngakho, le misebenzi ngeke yenziwe ngempumelelo, futhi ukusebenza okuphephile kwe-boiler akunakuqinisekiswa ngokuyisisekelo.
Okuvame kakhulu ukuthi lapho i-boiler isebenza ngokujwayelekile, ingaphezulu lokubekwa uphawu le-valve disc ne-valve isihlalo se-valve yokuphepha ivuza ngaphezulu kwezinga elivumelekile. Lokhu ngeke kubangele ukulahleka okuphakathi, kepha futhi kubangela ukulimala kwezinto ezinzima zokubopha uphawu. Ngakho-ke, izici kufanele zihlaziywe futhi zibhekane nesikhathi.
Kunezici ezintathu ezithile ezibangela ukuvuza kwe-booler ukuphepha. Ngakolunye uhlangothi, kungahle kube nokudonswa kwemfucumfucu eValve Searning ebusweni. Indawo yokubopha uphawu ayixubile, ibangela igebe ngaphansi kwesihlalo esiyisisekelo se-valve nesihlalo se-valve, bese kuvuza. Indlela yokuqeda lolu hlobo lwephutha ukuhlanza ukungcola kanye nemfucumfucu ewela endaweni yokubopha uphawu futhi uyisuse njalo. Udinga futhi ukunaka ukuhlolwa nokuhlanza ngezikhathi ezijwayelekile.
Ngakolunye uhlangothi, kungenzeka ukuthi indawo ebekelwe uphawu lendlela yokuphepha ye-boiler ilimele, okunciphisa kakhulu ubunzima bendawo yokubekwa uphawu, okwenza umsebenzi wokubekwa uphawu wehle. Indlela enengqondo kakhulu yokuqeda le nto ukunqamula indawo yokuqala yokubopha, bese uyiphinda kabusha ngokuya ngezidingo zokudweba ukuze uthuthukise ubulukhuni bendawo.
Enye into ebangelwa ukufakwa okungafanele noma usayizi wezingxenye ezihlobene mkhulu kakhulu. Ngesikhathi sokufakwa, isisekelo se-valve kanye nesihlalo asihambelani noma kunokuhanjiswa okukhanyayo endaweni ehlanganyelwe, bese kuba indawo ebeka uphawu lomgogodla we-valve kanye nesihlalo kubanzi kakhulu, okungafanele ukubopha uphawu.
Zama ukugwema ukuvela kwezinto ezifanayo. Ngaphambi kokusebenzisa i-boiler, kufanele uhlole ngokucophelela usayizi nokufana kwegebe elihambisanayo eliseduze komgogodla we-valve wokuphepha ukuze uqinisekise ukuthi umgodi ongumgogodla we-valve kanye nokubekwa uphawu Futhi ngokunciphisa ngokufanelekile ububanzi bendawo yokubekwa uphawu ngokuya ngezidingo zokudweba ukufezekisa ukubekwa uphawu okunengqondo nokusebenzayo ukuze kuncishiswe ukwenzeka kokuvuza.
