Kakaretso ea Li-Valves tsa Libolo tse phaphametseng tsa GB e Thata le e Bonolo: Ts'ebetso, Ts'ebeliso, le Maemo
Tekanyetso ea naha e bonolo le e tiisitsoeng ka thata ea bolo e phaphametseng ke valve e sebelisetsoang ho laola likanale tsa mokelikeli, tse nang le ts'ebetso e ntle ea ho tiisa le ho hanyetsa mokelikeli o monyenyane. Sehloohong sena, re tla hlahisa litšobotsi, lits'ebetso le lintlha tsa mantlha tsa ts'ebetso ea li-valve tsa bolo tse phaphametseng tse tiisitsoeng ka thata.
1. Likarolo tsa sehlahisoa
Tekanyetso ea naha e phaphametseng ka thata e tiisitsoeng e na le litšobotsi tse latelang:
-Ho hanyetsa metsi a tlaase: Li-valve tsa li-ball li na le ho hanyetsa metsi a tlaase ka ho fetisisa har'a mefuta eohle ea li-valve, esita le bakeng sa li-valve tsa bolo ea bophara bo fokotsehileng, ho hanyetsa metsi a bona ho batla ho le nyenyane.
- Ho bula le ho koala ka potlako le ho loketseng: Hafeela sefate sa valve se potoloha 90 °, valve ea bolo e tla qeta ho bula ka ho feletseng kapa ho koala ka ho feletseng, ho etsa hore ho be bonolo ho finyella ho bula le ho koala ka potlako.
- Ts'ebetso e ntle ea ho tiisa: Setulo sa valve ea bolo se koetsoe, ka ts'ebetso e ntle ea ho tiisa.
2. Tšebeliso ea Sehlahisoa
Tekanyetso ea naha e bonolo le e tiisitsoeng ka thata ea bolo e phaphametseng e loketse peterole, khase ea tlhaho, lik'hemik'hale, meriana, lijo, motlakase, phepelo ea metsi, metallurgy le liindasteri tsa kaho. Flange floating ball valve ke mokhoa o tloaelehileng oa ho hokahanya, o loketseng maemo a fapaneng a ho sebetsa.
3. Litlhaloso tse ka sehloohong tsa ts'ebetso
Khatello ea lebitso (MPa): Letoto la khatello ea lebitso la sekhahla sa naha se bonolo le se thata se tiisitsoeng sa bolo e phaphametseng ke 0.6 ~ 42.0 MPa, 'me maemo a loketseng a khatello a ka khethoa ho ea ka maemo a fapaneng a ho sebetsa.
Mocheso o sebetsang: Mocheso o sebetsang bakeng sa li-valve tsa bolo tse phaphametseng tse bonolo le tse tiisitsoeng ka thata ke -196 ℃~550 ℃, ha maemo a naha a phaphametseng ka sebabole a bonolo le a tiisitsoeng ka thata a loketse khase ea tlhaho, petroleum le mecha ea litaba e nang le H2S. le CO2.
Mecha ea litaba e sebetsang: Li-valve tsa bolo tse phaphametseng tse tiisitsoeng tsa naha li loketse mecha ea litaba e kang metsi, mouoane, petroleum, khase e metsi le khase ea tlhaho.
4. Lisebelisoa tsa karolo e ka sehloohong
Thepa e ka sehloohong ea lisebelisoa tsa naha e bonolo le e tiisitsoeng ka thata ea bolo e tiisitsoeng e kenyelletsa letoto la tšepe ea carbon, letoto la tšepe e sa hloekang, letoto la sebabole le letoto la tšepe le mocheso o tlase. Lisebelisoa tsena li ka finyella litlhoko tsa maemo a fapaneng a ho sebetsa, ho netefatsa ho tšoarella le ho tšepahala ha valve.
5. Litekanyetso tsa ho phethahatsa
Tekanyetso ea naha e phaphametseng ka thata le e tiisitsoeng ka thata e entsoe le ho etsoa ho latela litekanyetso tse kang GB/T12237, GB/T12221, GB/T12224, le GB/T12220. Litekanyetso tsena li totobatsa litlhoko tsa bolelele ba sebopeho, li-flange tse hokahanyang, tlhahlobo le tlhahlobo ea li-valve, ho netefatsa boleng ba sehlahisoa se tšepahalang.
Ka kakaretso, tekano ea naha e bonolo le e thata e tiisitsoeng ea bolo e phaphametseng ke valve e nang le ts'ebetso e ntle haholo, e sebelisoang haholo libakeng tse fapaneng tsa indasteri. Ho utloisisa litšoaneleho tsa eona, tšebeliso, le litlhaloso tsa mantlha tsa ts'ebetso ho ka re thusa ho khetha le ho sebelisa mofuta ona oa valve hantle.
