Valve ea Bellow Seal Globe ke eng: Tataiso ea ho Qetela

Ho Utloisisa Li-valve tsa Globe tsa Bellow Seal

Avalve ea globe ea tiiso e benyangke valve e khethehileng e thibang e etselitsoeng ho felisa ho dutla ha kutu lits'ebetsong tsa bohlokoa. Ho fapana le li-valve tsa setso tse pakiloeng tsa lefats'e, e sebelisa kopano ea tšepe e kopantsoeng 'meleng oa kutu le oa valve, e leng se etsang hore ho be le tiiso e sa keneng. Moralo ona oa bohlokoa bakeng sa ho sebetsana le mecha ea litaba e chefo, e senyang, kapa e hloekileng haholo moo mesi e tsoang e sa amoheleheng.

Likarolo tsa Bohlokoa tsa Li-valve tsa Bellow Seal Globe

• Moralo:Meqomo e nang le li-multi-ply (mealo e 8-12) bakeng sa ho tšoarella ha potoloho ea 10,000+
• Mosebetsi:E hatella/e atolosa nakong ea ts'ebetso ea valve ha e ntse e boloka botšepehi ba tiiso

2. 'Mele oa Valve

• Tekanyetso ea Khatello:Sehlopha sa 150 ho isa ho Sehlopha sa 2500 (ANSI/ASME B16.34)
• Qetella Likhokahano:Flanged (RF/RTJ), socket weld, kapa buttweld
• Boemo ba Mocheso:-196°C ho isa ho 550°C (mocheso o matla ho isa mochesong o phahameng)

3. Sefate le Disiki

• Kopano e kopaneng ea stem-disc e entsoeng bakeng sa ho hokahanya
• Ho thatafatsa bokaholimo (Stellite 6 coating) bakeng sa ho hanyetsa ho khohlela

4. Tiiso ea Bobeli (Bekha)

• Mehele ea ho paka ea graphite e ka tlase ho moriti e le e sireletsehileng

Valve ea Globe ea Bellow Seal e Sebetsa Joang?

Mohato oa 1: Ho Bula Valve

Ha lebili la letsoho le potoloha ka lehlakoreng le leng:

• Sefate sea phahama, se phahamisa diski setulong
• Li-bellow li hatella ka lehlakoreng le leng, li boloka botšepehi ba tiiso

Mohato oa 2: Ho Koala Valve

Ho potoloha ho ea ka oache:

• Matla a kutu a diski khahlanong le setulo, a emisa phallo
• Mekotla e atoloha ho fihlela boleleleng ba pele

Mohato oa 3: Thibelo ea ho Dutla ha Metsi

Ketso ea ho tiisa habeli:

• Tiiso ea mantlha: Tsela ea ho lutla ha kutu ea thipa ea Bellows
• Tiiso ea bobeli: Pakete ea Graphite (e latela API 622)

Melemo ho feta Li-valve tsa Globe tse Tloaelehileng

Likopo tsa Liindasteri

1. Ts'ebetso ea Lik'hemik'hale

• Dimela tsa chlor-alkali (sebaka sa ho thibela khase ea chlorine)
• Tlhahiso ea API ea Meriana

2. Oli le Khase

• Diyuniti tsa alkylation tsa HF
• Phetisetso ea cryogenic ea LNG (-162°C)

3. Tlhahiso ea Motlakase

• Ho itšehla thajana ha metsi a boiler
• Mekhoa ea ho palama turbine ea mouoane

Mekhoa ea Khetho

1. Mofuta oa Bellows

• Li-Bellow tse entsoeng ka maiketsetso:Khatello e phahameng (ASME Class 1500+)
• Li-Bellow tse Welded:Media e senyang (qetello e entsoeng ka motlakase)

2. Litšobotsi tsa Phallo

• Peresente e lekanang khahlanong le phallo e otlolohileng bakeng sa lits'ebetso tsa taolo

3. Lisetifikeiti

• NACE MR0175 bakeng sa tšebeletso e bolila
• PED 2014/68/EU bakeng sa mebaraka ea Europe

Bahlahisi ba Li-valve ba holimo ba China Bellow

Bahlahisi ba China ba kang NSW Valve Manufacturer ba fana ka:

• Meralo e lumellanang le API 602/BS 1873
• Phokotso ea litšenyehelo ea 30% ha e bapisoa le lihlahisoa tsa Europe
• Teko ea bellows e ikhethileng (ho lemoha ho lutla ha helium)

Mekhoa e Metle ea Tlhokomelo

• Tlhahlobo ea selemo le selemo ea mapetso a mokhathala
• Setlolo sa kutu se nang le mafura a mocheso o phahameng
• Qoba ho torque e feteletseng (max 50 Nm bakeng sa li-valve tsa DN50)
