He aha ka Bellow Seal Globe Valve: Ke alakaʻi hope loa

Ka hoʻomaopopo ʻana i nā ʻūhā poʻomanaʻo Bellow Seal Globe

Abellow seal globe valveʻO ka valve pani kūikawā i hoʻolālā ʻia e hoʻopau i ka leakage kumu i nā noi koʻikoʻi. ʻAʻole like me nā ʻūhā honua i hoʻopaʻa ʻia ma mua, hoʻohana ʻo ia i kahi hui bellow metala i hoʻopili ʻia i ke kumu a me ke kino valve, e hana ana i kahi sila hermetic. Pono kēia hoʻolālā no ka lawelawe ʻana i nā mea ʻawaʻawa, corrosive, a i ʻole ka maʻemaʻe kiʻekiʻe kahi i ʻae ʻole ʻia nā hoʻokuʻu mahuka.

Nā Mea Koʻikoʻi o Bellow Seal Globe Valves

1. Ahahui Bellows

• Material:Ke kila kila (SS316/316L), Inconel 625, a i ʻole Hastelloy C276
• Hoʻolālā:ʻO ka hoʻopaʻa ʻana i nā ʻāpana he nui (8-12 mau ʻāpana) no ka lōʻihi o 10,000+
• Hana:Hoʻopiʻi / hoʻonui i ka wā o ka hana valve me ka mālama pono ʻana i ka sila

2. Kino Valve

• Paʻi Paʻi:Papa 150 a i ka Papa 2500 (ANSI/ASME B16.34)
• Hoʻopau i nā pilina:Flanged (RF/RTJ), weld socket, a i ʻole buttweld
• Kaulana Maha:-196°C a 550°C (cryogenic i ka wela wela)

3. Puni & Disc

• ʻO ka hui pū ʻana i hoʻopaʻa ʻia no ka alignment
• ʻO ka paʻakikī o ka ʻili (Stellite 6 coating) no ka pale ʻana i ka abrasion

4. Sila ʻelua (Backup)

• Hoʻopili ʻia nā apo graphite ma lalo o ka bellow ma ke ʻano he palekana-palekana

Pehea ka hana ʻana o ka ʻūpā poʻomanaʻo Bellow Seal Globe

KaʻAnuʻu Hana 1: Wehe i ka Valve

Ke hoʻohuli ʻia ka huila lima ma ka ʻaoʻao ʻākau:

• Piʻi ke kumu, hāpai i ka diski mai ka noho
• Hoʻopiʻi ʻo Bellows i ke axially, mālama i ka pono o ka sila

KaʻAnuʻu Hana 2: Hoʻopau i ka Valve

Ka hoʻololi ʻana i ka uaki:

• Hoʻokuʻu ke kumu i ka disc i ka noho, hoʻōki i ke kahe
• Hoʻonui ka bellow i ka lōʻihi kumu

KaʻAnuʻu 3: Kāohi Leakage

ʻO ka hana hoʻopaʻa ʻana pālua:

• Sila mua: Hoʻopaʻa ka Bellows i ke ala leakage kumu
• Sila lua: Graphite packing (API 622 compliant)

Nā Pōmaikaʻi ma mua o nā ʻūhā Globe maʻamau

Noi Hana Hana

1. Ka Hana Kemika

• Nā mea kanu Chlor-alkali (hoʻopaʻa kinoea chlorine)
• Hana API lāʻau lapaʻau

2. Aila & Gas

• HF alkylation units
• LNG cryogenic hoʻoili (-162°C)

3. Mana Mana

• ʻO ka hoʻokaʻawale ʻana i ka wai hānai paila
• Pūnaehana hoʻoheheʻe mokuahi

Koho Koho

1. ʻAno Bellows

• Nā Bellows Forged:Pumi kiʻekiʻe (Papa ASME 1500+)
• Weled Bellows:Mea hoʻoheheʻe ʻia (hoʻopau electropolished)

2. Nā ʻano kahe

• Pākēneka like me ke kahe laina no nā noi hoʻomalu

3. Nā palapala hōʻoia

• NACE MR0175 no ka lawelawe ʻawaʻawa
• PED 2014/68/EU no nā mākeke ʻEulopa

ʻO nā mea hana kiʻekiʻe Kina Bellow Valve

Hāʻawi nā mea hana Kina e like me NSW Valve Manufacturer:

• API 602/BS 1873 hoʻolālā kūpono
• ʻO 30% ka mālama kālā vs
• ʻO ka hoʻāʻo ʻana i ka bellows maʻamau (ʻike leak helium)

ʻO nā hana maikaʻi loa o ka mālama ʻana

• Ka nānā ʻana o ka bellows i kēlā me kēia makahiki no nā māwae luhi
• Lubrication kumu me ka momona wela wela
• Hōʻalo i ka hoʻoulu ʻana (max 50 Nm no nā kiwi DN50)
