Ingqiqo yokusetyenziswa kwezixhobo zevalvu kwizixhobo zesinyithi: Ukusuka kwisihlalo sevalvu ukuya kwishafti esezantsi
Kwiinkqubo zolawulo ezinkulu kwishishini lesinyithi, ukusebenza kweevalvu zebhola kunye nokufakelwa kweevalvu zesango kuchaphazela ngokuthe ngqo ukuzinza kokusebenza kwemibhobho ye-oven kunye neenkqubo zamanzi okupholisa. Rhoqo, ingxaki ebaleni ayikokuyilwa kweevalvu iyonke, kodwa kumacandelo ambalwa amancinci nangabonakaliyo - njengokutshona kwesihlalo, ukuphambuka kwesithuba esisezantsi, okanye ukudinwa kwebhokisi yokuzalisa umbane ngenxa yokuguga. Ukuba olu hlobo lwengxaki luyaqokelelana, ukujikeleza kwesphere akusekho endaweni, kwaye ukuphambuka kokuvula nokuvala kuya kuba kukusilela kwenkqubo.
Kwiminyaka yakutshanje, siye safanisa iiprojekthi zevalvu ye-oxygen main pipe kunye ne-coke oven main line ball valve kwiifektri ezininzi zentsimbi, kwaye iingxaki eziqhelekileyo zigxile kwisakhiwo se-valve stem kunye nobomi besihlalo sentwasahlobo. Imizobo yokuqala yomthengi isebenzise isihlalo sevalvu esivaliweyo esidibeneyo, kodwa i-spring thrust iyasilela ngokukhawuleza phantsi kokuvulwa nokuvalwa okuqhelekileyo, kwaye umphezulu wokutywina kunzima ukuwufaka. Silungise isakhiwo, satshintshela kwisihlalo sentwasahlobo esahluliweyo esinomda weendlela ezimbini, kwaye ukumelana nokuguguleka kwe-shaft esezantsi kunye neringi yokuxhasa kuphuculwe kakhulu emva konyango lwe-nitriding.
Kwicandelo elifana nomngxuma osezantsi, iimfuno azinzima, kodwa kufuneka zilungelelaniswe kwaye zingabi nakumelana. Ukuba ibhola kunye nomngxuma azilungelelaniswanga, nokuba ukusebenza kwe-actuator kulungile, isantya sokuvula nokuvala siya kulungiswa yimpazamo. Xa sihambelana, ngokusisiseko sifuna abathengi ukuba banike zombini umbindi webhola kunye nolwakhiwo lomngxuma ongaphezulu ukuze kulawulwe i-coaxiality.
Kolu hlobo lweprojekthi yokuxhasa, 'iindawo ezincinci zesakhiwo' ezifana neebrakethi, iibhonethi, kunye nee-stem nuts zihlala zizinto eziphambili ezimisela ubomi benkonzo yomatshini wonke. Azibandakanyeki ngokuthe ngqo ekutywineni, kodwa zichonga ukuba ukuvulwa nokuvalwa kuhamba kakuhle na. Abahlobo abenza urhwebo lwangaphandle basenokuba badibene nabo: xa umthengi evavanya, akukokujonga inkangeleko, kodwa kukuchitha imizobo yendibano umaleko ngomaleko ukuze kubonwe ukuba ukuchaneka kwezi ndawo zincinci kusemgangathweni na.
Ngoko ke, nokuba ukufakwa kwevalvu, musa ukuyijonga njengento encinci, iingxaki zoyilo kunye nokucubungula zinokubonakala ngexesha lokuhlanganiswa kwindawo. Xa senza olu hlobo lweprojekthi, siya kucebisa ngokufanayo ukuba abathengi bathumele imizobo ukuqinisekisa isicwangciso, kunye nokulungiswa kunye nokuhlanganiswa ngaphambi kokuba kuhlanganiswe, ngakumbi kwizakhiwo ezidibanisa ezinye ezifana nezihlalo zevalvu, izihlalo zentwasahlobo, kunye neziqu zevalvu.
