2. Khethollo le litšobotsi tsa li-valve tsa ho hlahloba tse tsoang linaheng tse ling
Cheka valve:
1. Ho ea ka sebopeho, e ka aroloa ka mefuta e meraro: phahamisa ho hlahloba valve, swing check valve le serurubele hlahloba valve.
①Lift check valve e ka aroloa ka mefuta e 'meli: e otlolohileng le e otlolohileng.
② Li-valve tsa ho hlahloba li-swing li arotsoe ka mefuta e meraro: sekoti se le seng, sekoti se le seng, se nang le liphahlo tse peli le liphahlo tse ngata.
③ Butterfly check valve ke mofuta o otlolohileng.
Mefuta ea khokahanyo ea li-valve tsa ho hlahloba ka holimo e ka aroloa ka mefuta e meraro: khokahanyo ea khoele, khokahanyo ea flange le welding.
Ka kakaretso, li-valve tsa ho hlahloba tse otlolohileng (bophara bo bonyenyane) li sebelisoa liphaepheng tse tšekaletseng tse nang le bophara ba 50mm. Sesepa se otlolohileng sa ho hlahloba se phahamisa se ka kenngoa liphaepheng tse tšekaletseng le tse theohileng. Belofo e ka tlase hangata e kenngoa feela phaepheng e emeng ea pompo, 'me e bohareng e phalla ho tloha tlase ho ea holimo. Li-valve tsa ho phahamisa li-check li sebelisoa moo ho koaloang ka potlako ho hlokahalang.
The swing check valve e ka etsoa khatello e phahameng haholo ea ho sebetsa, PN e ka fihla 42MPa, 'me DN e ka boela ea etsoa e kholo haholo, e kholo ka ho fetisisa e ka fihla ho feta 2000mm. Ho itšetlehile ka thepa ea khetla le tiiso, e ka sebelisoa leha e le efe ea ho sebetsa le mocheso ofe kapa ofe oa mocheso o sebetsang. Mocheso ke metsi, mouoane, khase, sebaka se senyang, oli, lijo, meriana, joalo-joalo. Mocheso o mahareng o sebetsang o pakeng tsa -196~800℃. Ketsahalo e sebetsang ea valve ea ho hlahloba serurubele ke khatello e tlaase le bophara bo boholo.
3. Khetho ea valve ea ho hlahloba mouoane e lokela ho finyella litlhoko tse latelang
1. Khatello ka kakaretso e lokela ho khona ho mamella PN16 kapa ho feta
2. Thepa ka kakaretso ke tšepe e entsoeng ka tšepe le tšepe e sa hloekang, kapa tšepe ea chrome-molybdenum. Ha e loketse ho sebelisa tšepe e entsoeng ka tšepe kapa koporo. U ka khetha li-valve tsa tlhahlobo ea tšepe e tsoang kantle ho naha le li-valve tsa ho hlahloba litšepe tse sa hloekang tse tsoang kantle ho naha.
3. Ho hanyetsa mocheso ho tlameha ho ba bonyane likhato tse 180. Ka kakaretso, li-valve tsa ho hlahloba tse tiisitsoeng ka bonolo li ke ke tsa sebelisoa. Ho ka khethoa li-valve tsa tlhahlobo tse tsoang kantle ho naha kapa li-valve tsa tlhahlobo tse tsoang kantle ho naha, 'me ho sebelisoa litiiso tse thata tsa tšepe e sa hloekang.
4. Mokhoa oa ho hokahanya ka kakaretso o amohela khokahanyo ea flange
5. Sebopeho sa sebopeho ka kakaretso se amohela mofuta oa swing kapa mofuta oa lifti.
