Li-valve tsa Ball tsa Boholo bo Boholo: Tataiso ea ho Hlophisa le Khetho ea Moetsi

Li-valve tsa bolo ke likarolo tsa bohlokoa lits'ebetsong tsa liphaephe tsa indasteri, tse etselitsoeng ho laola phallo ea metsi, likhase, kapa slurry. Sebopeho sa tsona se bonolo empa se tiile—se nang le bolo e potolohang e nang le mokoti—se netefatsa ho koaloa ho tšepahalang le ho theoha ho fokolang ha khatello. Empa ha merero e hlokali-valve tsa bolo tse kholo(hangata e hlalosoa e le di-valve tse bophara ba lisenthimithara tse 12/300 mm kapa ho feta), ho khetha moralo le moetsi ea nepahetseng ho ba bohlokoa. Tataiso ena e hlahloba ho hlophisoa ha di-valve tsa bolo tse bophara bo boholo le mokhoa oa ho khetha mofani ea tšepahalang.

Li-valve tsa Ball tsa Boholo bo Boholo ke Life

Li-valve tsa bolo tse kholo ke li-valve tse boima tse entsoeng bakeng sa lits'ebetso tse phallang haholo liindastering tse kang oli le khase, kalafo ea metsi, tlhahiso ea motlakase le ts'ebetso ea lik'hemik'hale. Bophara ba tsona bo boholo ba li-bore (lisenthimithara tse 12–60+) li li lumella ho sebetsana le likhatello tse feteletseng, mocheso le litlhoko tsa volumetric.

Likarolo tsa Bohlokoa:

• Kaho e Matla:E entsoe ka thepa e kang tšepe e sa ruseng, tšepe ea khabone, kapa motsoako ho mamella maemo a thata.
• Ho Tiisa ho Tsoetseng Pele:Litulo tse tsitsitseng (mohlala, PTFE, tšepe ho tloha ho tšepe) li thibela ho dutla ha metsi libakeng tse nang le khatello e phahameng.
• Dikgetho tsa Tshebetso:Ts'ebetso ea letsoho, ea pneumatic, ea hydraulic, kapa ea motlakase bakeng sa taolo e iketsang.

Tlhophiso ea Li-valve tsa Ball tsa Boholo bo Boholo

Ho utloisisa mefuta ea li-valve ho netefatsa ts'ebetso e ntle bakeng sa lits'ebetso tse ikhethileng:

1.Ka Moralo

• Li-valve tsa bolo tse phaphametseng:Bolo e tshwarwa sebakeng sa yona ka ho hatelloa ho tloha ditulong tsa di-valve. E loketse ditsamaiso tsa kgatello e tlase ho isa ho e mahareng.
• Li-valve tsa Ball tse fanyehiloeng ka Trunnion:Bolo e tlamiloe ka shaft ea trunnion, e fokotsang ho senyeha ha setulo. E loketse liphaephe tse nang le khatello e phahameng le tse kholo.

Hlokomela: Li-valve tsa bolo tse kholo hangata ke li-valve tsa bolo tse kentsoeng ka har'a trunnion.

2.Ka Boitsebiso

• Ts'epe e sa beng le mabali:E hanela mafome bakeng sa dibaka tsa dikhemikhale kapa tsa lewatle.
• Tšepe ea Khabone:E theko e tlase bakeng sa litsamaiso tsa oli le khase tse nang le khatello e phahameng.
• Li-Alloys tsa Cryogenic:E entsoe bakeng sa mocheso o ka tlase ho lefela lits'ebetsong tsa LNG.

3.Ka Khokahano ea Qetellong

• E flanged:E tloaelehile liphaepheng tse kholo bakeng sa ho e kenya habonolo.
• E tjhesellelitsoe:E fana ka tiiso e sa feleng, e sa dutleng bakeng sa litsamaiso tsa bohlokoa.

Mokhoa oa ho Khetha Valve e Kholo ea Boholo ba Ball e Nepahetseng

Ho khetha moetsi ea tšepahalang ho netefatsa hore o phela nako e telele, o sireletsehile, 'me o latela melao. Tsena ke lintho tseo u lokelang ho li etelletsa pele:

1.Phihlelo ea Indasteri le Botumo

Batla bahlahisi ba nang le rekoto e pakiloeng ea ho hlahisa li-valve tse bophara bo boholo bakeng sa lekala la hau. Hlahloba litifikeiti (mohlala, API 6D, ISO 9001) le bopaki ba bareki.

2.Bokgoni ba ho iketsetsa

Hangata merero e meholo e hloka ditharollo tse ikgethileng. Netefatsa hore mofani wa thepa o fana ka:

• Boholo ba libore tse ikhethileng, litekanyetso tsa khatello, le thepa.
• Liaparo tse khethehileng (mohlala, tse thibelang ho bola, tse sireletsehileng mollong).

3.Netefaletso ea boleng

Netefatsa hore moetsi o latela mekhoa e tiileng ea taolo ea boleng, ho kenyeletsoa:

• Teko e sa senyeheng (NDT) bakeng sa botšepehi ba weld.
• Teko ea khatello ho netefatsa ts'ebetso tlas'a maemo a feteletseng.

4.Tšehetso ea Kamora Thekiso

Khetha molekane ea fanang ka tšehetso ea tekheniki, lits'ebeletso tsa tlhokomelo, le likarolo tse ling tse fumanehang habonolo.

5.Theko khahlanong le Boleng

Leha litheko li le bohlokoa, beha boleng ba nako e telele pele. Li-valve tse theko e tlase li ka boloka litšenyehelo tsa pele empa li lebisa ho hloleheng khafetsa le ho se sebetse.

Mehopolo ea ho Qetela

Li-valve tsa bolo tse khololi bohlokoa haholo litsamaisong tsa indasteri tse hlokang bokhoni bo phahameng ba phallo le ho tšoarella. Ka ho utloisisa lihlopha tsa tsona le ho sebelisana le moetsi ea nang le boiphihlelo, u ka netefatsa katleho ea ts'ebetso le polokeho. Kamehla beha pele litifikeiti tsa boleng, likhetho tsa ho iketsetsa, le tšehetso ea kamora ho reka ha u ntse u hlahloba bafepedi.

Bakeng sa temohisiso e batsi mabapi le khetho ea li-valve, hlahloba litataiso tsa rona tsa tekheniki kapa ikopanye le sehlopha sa rona sa boenjiniere bakeng sa likhothaletso tse ikhethileng.
