Yintoni iValve yeglowubhu yeSitywina eHard?
I-Hard Seal Globe Valve yivalve yokulawula ukuhamba kwemizi-mveliso esebenzisa i-metal-to-metal isakhiwo sokutywina kunokuthembela ngokukodwa kwizinto ezithambileyo zokutywina. I-Huadu iphuhlisa olu hlobo lwevalve yokufuna indawo zemibhobho apho ubushushu, uxinzelelo, ukuqhawuka, kunye nokusebenza okuphindaphindiweyo kunokubeka uxinzelelo olukhulu kumacandelo okutywinwa okuqhelekileyo.
Ivalve ngokuqhelekileyo isebenzisa umzimba wohlobo lweglowubhu kunye nediski eshukumayo ehamba ukuya okanye kude nesihlalo. Le ntshukumo ivumela i-valve ukuba yenze imisebenzi emibini ebalulekileyo: ukuvala ukuhamba kwemibhobho kunye nokulawula izinga lokuhamba. Xa kuthelekiswa nevalve elula yokuzahlula, ubumbeko lweglowubhu lubonelela ngolawulo olungcono lokushukuma kwamanzi.
Ngeenkonzo ezifunayo, iindawo zokutywina zinokuqina nge-Stellite okanye ezinye izinto ezifanelekileyo zokunxiba. Olu lwakhiwo lunceda ekunciphiseni ukuthotywa okubangelwa kukukhuhlana, ukhukuliseko, kunye nokusebenza okunobushushu obuphezulu.
Ngokweenkcazo zemveliso, i-Huadu ye-Hard Seal Globe Valve inokuqwalaselwa nge-carbon steel okanye ukwakhiwa kwensimbi engenasici, iiklasi zoxinzelelo ezininzi, kunye neendlela ezininzi zokusebenza, okwenza ukuba zilungelelanise iiprojekthi ezahlukeneyo zoshishino.
Isebenza Njani iValve yeGlobe ye-Hard Seal?
Umgaqo wokusebenza uqondile kodwa usebenza kakhulu. Xa i-valve ivuliwe, i-disc isuka kude nesihlalo, idala i-flow passage. Xa i-handwheel, i-actuator, okanye indlela yokusebenza ihambisa isiqu kwelinye icala, idiski isondela kwisihlalo kwaye inciphisa ngokuqhubekayo ukuhamba.
Uqhagamshelwano lwentsimbi ukuya kwintsimbi phakathi kwediski kunye nesihlalo senza ujongano oluphambili lokutywinwa. Xa zenziwe ngobunjineli ngokufanelekileyo kwaye zenziwe, iindawo ezinobuso obunzima zinokunika ukuxhathisa okuqinileyo ngokuchasene nokuguga kunye nokhukuliseko ngexesha elifuna inkonzo.
Ulandelelwano oluqhelekileyo lokusebenza lubandakanya:
- Umsebenzisi ujikelezisa ivili lesandla okanye avule i actuator ekhethiweyo.
- Isiqu sidlulisela amandla okusebenza kwidiski yevalvu.
- I-disc ishukuma ngokumalunga nesihlalo ukulawula i-flow passage.
- Njengoko i-disc ifikelela kwisihlalo, iindawo zokutywina zetsimbi ziseka ukuvala.
- Xa iphinda ivulwa, idiski isuka kude nesihlalo ukuze ibuyisele ukuhamba kombhobho.
Le ntshukumo yomgca elawulekayo sesinye sezizathu zokuba iivalvu zeglowubhu zikhethwa rhoqo xa zifuneka zodwa kunye nokukwazi ukugoba.
