Uma kuziwa kuma-valve okuphepha, wonke umuntu uyazi ukuthi lena i-valve yokuvikela ebaluleke kakhulu.Ngokuyisisekelo isetshenziswa kuzo zonke izinhlobo zemikhumbi yokucindezela kanye nezinhlelo zamapayipi.Yiqiniso, ayishoda emishinini ye-boiler.Lapho ingcindezi ohlelweni olucindezelweyo ingaphezu kwenani lomkhawulo, i-valve yokuphepha ingakwazi ukuvula ngokuzenzakalelayo futhi ikhiphe okuphakathi ngokweqile emkhathini ukuze kuqinisekiswe ukusebenza okuphephile kwe-boiler futhi igweme izingozi.
Lapho ukucindezela ohlelweni lwe-boiler kwehla ngaphakathi kwendawo edingekayo, i-valve yokuphepha nayo ingavala ngokuzenzakalelayo.Ngakho-ke, uma kunenkinga ngakho, le misebenzi ngeke yenziwe ngempumelelo, futhi ukusebenza okuphephile kwe-boiler akukwazi ukuqinisekiswa ngokuyisisekelo.
Okuvame kakhulu ukuthi uma i-boiler isebenza ngokujwayelekile, indawo yokuvala ye-valve disc kanye nesihlalo se-valve ye-valve yokuphepha ivuza ngaphezu kwezinga elivumelekile.Lokhu ngeke nje kubangele ukulahlekelwa okuphakathi, kodwa futhi kubangele ukulimala kokuvala okunzima.Ngakho-ke, izici kufanele zihlaziywe futhi kubhekwane nazo ngesikhathi.
Kunezici ezintathu eziqondile ezibangela ukuvuza kwe-valve yokuphepha ye-boiler.Ngakolunye uhlangothi, kungase kube nemfucumfucu endaweni yokuvala i-valve.Indawo yokuvala ivaliwe, ibangele igebe ngaphansi komgogodla we-valve nesihlalo se-valve, bese iyavuza.Indlela yokuqeda lolu hlobo lwephutha ukuhlanza ukungcola kanye nemfucumfucu ewele endaweni yokuvala futhi isuse njalo.Udinga futhi ukunaka ukuhlolwa nokuhlanza ngezikhathi ezijwayelekile.
Ngakolunye uhlangothi, kungenzeka ukuthi indawo yokubeka uphawu yendlela yokuphepha ye-boiler yonakalisiwe, okunciphisa kakhulu ukuqina kwendawo yokubeka uphawu, ngaleyo ndlela kubangele umsebenzi wokufaka uphawu wehle.Indlela enengqondo kakhudlwana yokuqeda lesi senzakalo ukusika indawo yokuvala yasekuqaleni, bese uyifaka kabusha ngokuvumelana nezidingo zokudweba ukuze kuthuthukiswe ubulukhuni bobuso bendawo yokuvala.
Esinye isici sibangelwa ukufakwa okungalungile noma ubukhulu bezingxenye ezihlobene bukhulu kakhulu.Ngesikhathi sokufakwa, umgogodla we-valve nesihlalo akuhambisani noma kukhona ukukhanya okudluliswayo endaweni ehlangene, bese kuthi indawo yokuvala ye-valve core nesihlalo sivuleke kakhulu, okungahambisani nokuvala.
Zama ukugwema ukuvela kwezimo ezifanayo.Ngaphambi kokusebenzisa i-boiler, kufanele uhlole ngokucophelela ubukhulu kanye nokufana kwegebe elihambisanayo elizungeze umnyombo we-valve yokuphepha ukuze uqinisekise ukuthi imbobo eyinhloko ye-valve kanye nendawo yokuvala kuqondile;futhi unciphise ngokufanele ububanzi bendawo yokuvala ngokuvumelana nezidingo zomdwebo ukuze kufinyelelwe ukuvala okunengqondo nokuphumelelayo ukuze kuncishiswe ukuvela kokuvuza.
