Buku Lotsogolera ku Ma Valves a Cryogenic: Mitundu, Zipangizo, ndi Mapulogalamu

Kodi Valavu ya Cryogenic ndi chiyani?

Valavu yofiirandi valavu yapadera yamafakitale yopangidwa kuti igwire ntchito m'malo otentha kwambiri, nthawi zambiri pansi pa -40°C (-40°F) komanso pansi pa -196°C (-321°F). Mavalavu amenewa ndi ofunikira kwambiri pothana ndi mpweya wosungunuka monga LNG (gasi wachilengedwe wosungunuka), nayitrogeni wamadzimadzi, mpweya, argon, ndi helium, kuonetsetsa kuti madzi akuyenda bwino komanso kupewa kutuluka kwa madzi m'makina a cryogenic.

Mitundu ya Ma Valves a Cryogenic

1. Valavu ya Mpira wa Cryogenic: Ili ndi mpira wozungulira wokhala ndi bowo lowongolera kuyenda kwa madzi. Yabwino kwambiri kuti izimitsidwe mwachangu komanso kuti mphamvu yamagetsi isachepe kwambiri.

2. Valavu ya Gulugufe ya Cryogenic: Imagwiritsa ntchito diski yozunguliridwa ndi tsinde kuti igwire kapena kuipatula. Yaing'ono komanso yopepuka, yoyenera mapaipi akuluakulu.

3. Valavu ya Chipata cha Cryogenic: Imagwiritsa ntchito diski yofanana ndi chipata yowongolera kuyenda kolunjika. Yabwino kwambiri potsegula/kutseka kwathunthu komanso yolimba pang'ono.

4. Valavu ya Cryogenic Globe: Yopangidwa ndi thupi lozungulira komanso pulagi yosunthika kuti iyendetse bwino kayendedwe ka madzi m'makina a cryogenic.

Magulu a Kutentha kwa Ma Valves a Cryogenic

Ma valve a cryogenic amagawidwa m'magulu kutengera kutentha komwe kumagwiritsidwa ntchito:

- Ma Valves Otentha Kwambiri: -40°C mpaka -100°C (monga, CO₂ yamadzimadzi).

- Ma Valves Otentha Kwambiri: -100°C mpaka -196°C (monga LNG, nayitrogeni yamadzimadzi).

- Ma Valves Oopsa Kwambiri: Pansi pa -196°C (monga, helium yamadzimadzi).

The-196°C valavu yozungulirandi imodzi mwa zinthu zovuta kwambiri, zomwe zimafuna zipangizo zamakono komanso kapangidwe kake.

Kusankha Zinthu za Ma Valves a Cryogenic

- Thupi ndi KukongoletsaChitsulo chosapanga dzimbiri (SS316, SS304L) choteteza dzimbiri komanso kulimba.

- Mipando ndi Zisindikizo: PTFE, graphite, kapena elastomers zomwe zimayesedwa kuti zigwirizane ndi kutentha kochepa.

- Bonnet Yowonjezera: Zimaletsa kutentha kusamutsidwa kupita ku tsinde, zomwe ndizofunikira kwambiri pakugwira ntchito bwino kwa valavu ya cryogenic ya -196°C.

Ma Valves a Cryogenic vs. Ma Valves Okhazikika ndi Otentha Kwambiri

- KapangidweMa valve opangidwa ndi cryogenic ali ndi ma stems/bonnet otambasuka kuti alekanitse zisindikizo ndi madzi ozizira.

- ZipangizoMa valve okhazikika amagwiritsa ntchito chitsulo cha kaboni, chosayenerera kuphwanyika kwa cryogenic.

- KutsekaMabaibulo a Cryogenic amagwiritsa ntchito zisindikizo zotsika kutentha kuti zisatuluke.

- KuyesaMa valve a cryogenic amayesedwa kuti atsimikizire momwe zinthu zilili.

Ubwino wa Ma Valves a Cryogenic

- Magwiridwe Osatayikira: Palibe mpweya woipa womwe umatuluka mumlengalenga mukazizira kwambiri.

- Kulimba: Yolimba ku kutentha ndi kuipitsidwa kwa zinthu.

- Chitetezo: Yopangidwa kuti igwire ntchito yothana ndi kusinthasintha kwa kutentha mwachangu.

- Kusamalira Kochepa: Kapangidwe kolimba kamachepetsa nthawi yogwira ntchito.

Kugwiritsa Ntchito Ma Valves a Cryogenic

- Mphamvu: Kusunga, kunyamula, ndi kubwezeretsanso gasi wa LNG.

- Chisamaliro chamoyo: Makina a gasi azachipatala (oxygen yamadzimadzi, nayitrogeni).

- Zamlengalenga: Kusamalira mafuta a roketi.

- Mpweya wa Mafakitale: Kupanga ndi kufalitsa madzi a argon, helium.

Wopanga Ma Vavu a Cryogenic - NSW

NSW, mtsogolerifakitale ya ma valve a cryogenicndiwogulitsa, imapereka ma valve ogwira ntchito bwino kwambiri m'mafakitale ofunikira. Mphamvu zazikulu:

- Ubwino Wotsimikizika: ISO 9001, API 6D, ndi CE zikugwirizana.

- Mayankho Amakonda: Mapangidwe opangidwa kuti agwiritsidwe ntchito pa ma valve a cryogenic a -196°C.

- Kufikira Padziko Lonse: Imadaliridwa ndi mafakitale a LNG, malo opangira mankhwala, ndi makampani akuluakulu oyendetsa ndege.

- Zatsopano: Zipangizo zokhala ndi patent komanso mapangidwe a tsinde kuti zigwiritsidwe ntchito kwa nthawi yayitali.

Onani mitundu yosiyanasiyana ya NSWmavavu a mpira wa cryogenic, mavavu a gulugufendimavavu a chipatayopangidwa kuti ikhale yodalirika m'mikhalidwe yovuta kwambiri.
