Ball valve ke karolo ea bohlokoa tsamaisong efe kapa efe ea liphaephe, e fanang ka mokhoa o bonolo le o sebetsang oa ho laola phallo ea metsi le likhase.Har'a mefuta e sa tšoaneng ea li-valve tsa bolo e fumanehang, li-valve tse peli tsa bolo ke khetho e ratoang ka lebaka la ho feto-fetoha ha tsona le ho tšepahala.Sehloohong sena, re tla hlahloba tšebeliso ea li-valve tsa bolo, nako ea ho sebelisa li-valve tse nang le likarolo tse peli, le melemo ea ho khetha khetho ea boleng bo phahameng ho tsoa ho mofani oa li-valve ea nang le botumo bo botle.
Morero oa valve ea bolo ke ofe?
Sepheo se seholo sa li-valve tsa bolo ke ho laola ho phalla ha maro a liphaephe.E na le disk e chitja (kapa bolo) e nang le lesoba bohareng, e ka fetoloang ho lumella kapa ho thibela ho phalla ha mecha ea litaba.Ha thebelofo ea boloe sebakeng se bulehileng, sekoti se tsamaisana le phala, se lumellang mecha ea phatlalatso hore e fete.Ha e le sebakeng se koetsoeng, sekoti se pota-potile phala, se thibela ho phalla.
Li-valve tsa bolo li atisa ho sebelisoa liindastering tse sa tšoaneng, ho akarelletsa le oli le khase, lik'hemik'hale tsa petrochemicals, metsi le metsi a litšila, ho hlahisa matla le tse ling.Li ratoa ka lebaka la bokhoni ba tsona ba ho koala kapele le ka botšepehi, hammoho le bokhoni ba tsona ba ho mamella likhatello tse phahameng le mocheso.
Ke lokela ho sebelisa belofo ea likoto tse peli neng?
A valve ea likotoana tse pelike mofuta o khethehileng oa valve ea bolo e nang le likarolo tse peli tse arohaneng, 'mele le cap cap.Moqapi ona o bonolo ho o boloka le ho lokisoa kaha valve e ka qhaqhoa ntle le ho e ntša phala.E loketse lits'ebetso tse hlokang ho lokisoa kapa ho hlahlojoa khafetsa, le litsamaiso tse ka hlokang ho fetoloa kapa ho ntlafatsoa nakong e tlang.
Valve e tsitsitseng ea likotoana tse peli e hlahisoang ke CEPAI e sebelisoa haholo ho khaola kapa ho hokela bohareng ba phala.E ka sebelisoa ka metsi, mouoane, oli, khase e metsi, khase ea tlhaho, khase ea mashala, asiti ea nitric, urea le mecha e meng ea litaba.Sena se etsa hore e be khetho e fapaneng bakeng sa lits'ebetso tse fapaneng tsa indasteri tse ka hlokang taolo ea mefuta e fapaneng ea mecha ea litaba.Ho phaella moo, moralo oa trunnion o tiisa botsitso le tšehetso e kholoanyane bakeng sa bolo, ho lumella likhatello tse phahameng le boholo bo boholo.
Ho khetha mofani oa li-valve tse nepahetseng ho bohlokoa ho netefatsa boleng le ts'ebetso ea valve.Barekisi ba tsebahalang joalo ka CEPAI ba fana ka mefuta e mengata ea likhetho ho lumellana le litlhoko tse fapaneng mme lihlahisoa tsa bona li etsoa ho latela maemo a machabeng ho netefatsa ts'epo le ho tšoarella.
Qetellong, li-valve tsa bolo li phetha karolo ea bohlokoa ho laola ho phalla ha metsi liphaepheng, 'me li-valve tsa bolo ea likarolo tse peli ke khetho e fapaneng le e sebetsang bakeng sa lits'ebetso tse ngata.Ke khetho e tsebahalang ho pholletsa le liindasteri ka lebaka la boiketlo ba eona ba tlhokomelo le tokiso le bokhoni ba ho sebetsana le mefuta e mengata ea matla a mahareng le a phahameng.Ha u khetha li-valve tse peli tsa bolo, ke habohlokoa ho nahana ka litlhoko tse khethehileng tsa tsamaiso le ho khetha mofani oa thepa ea ka tšeptjoang ho netefatsa boleng le ts'ebetso ea valve.
