Valavu ya Gulugufe Wachitatu Wopanda Kuyika

Valavu ya Gulugufe Yopatukana Katatu: Chidule Chathunthu cha Zamalonda

Kodi Valavu ya Gulugufe Yopatukana Katatu ndi Chiyani?

A valavu ya gulugufe yotsika katatu(TOBV) ndi valavu yamafakitale yogwira ntchito bwino kwambiri yopangidwira kuwongolera kayendedwe ka madzi moyenera pakugwiritsa ntchito molimbika. Mawonekedwe ake apadera amachepetsa kuwonongeka, amatsimikizira kutsekedwa kolimba ngati thovu, ndipo amagwira ntchito bwino kutentha kwambiri komanso kupsinjika. Mosiyana ndi valavu wamba.mavavu a gulugufeTOBV imagwiritsa ntchitokapangidwe ka eccentric katatukuti athetse kukangana pakati pa diski ndi mpando panthawi yogwira ntchito, zomwe zimapangitsa kuti ikhale yoyenera pa ntchito zofunika kwambiri.

Kumvetsetsa Kapangidwe ka "Triple Offset"

Mawu oti "triple offset" amatanthauza mitundu itatu yosiyana ya geometric yomwe imapangidwira valavu:

1. Kuchotsera Koyamba: Chogwirira cha valavu chili kumbuyo kwa mzere wapakati wa mpando, zomwe zimathandiza kuti diski izizungulira popanda kukhudza mpando.

2. Kuchotsera Kwachiwiri: Shaft imachotsedwa pakati pa payipi, zomwe zimapangitsa kuti pakhale kuyenda kofanana ndi kamera kuti igwire bwino ntchito.

3. Kuchotsera Kachitatu: Pamwamba pa mpando pali ngodya (conical profile), zomwe zimapangitsa kuti pakhale kutsekeka komwe kumawonjezera kutseka valavu ikatsekedwa.

Kapangidwe kameneka kamachotsa kukangana kotsetsereka, kamachepetsa kuwonongeka, ndipo kamateteza kuti pasakhale kutuluka kwa madzi ngakhale mutagwiritsa ntchito nthawi yayitali.

Mafotokozedwe Ofunika

Makulidwe a Vavu

- Mtundu Woyenera:2" mpaka 48" (DN50 mpaka DN1200).

- Kukula Kwapadera:Ikupezeka pa zosowa zapadera zamafakitale.

Mavoti Opanikizika

- Makalasi a ANSI: 150 mpaka 600.

- Ma PN Ratings: PN16 mpaka PN100.

- Yoyenera makina amphamvu kwambiri mpaka 1,450 psi (100 bar).

Mitundu Yolumikizira

- Zopindika:ANSI, DIN, kapena JIS flanges wamba.

- Wafer/Lug:Kapangidwe kakang'ono ka malo okhazikika.

- Kulukana kwa Matako:Kwa makina okhazikika komanso okhazikika a mapaipi.

Zipangizo

- Thupi/Kukongoletsa:Chitsulo chosapanga dzimbiri (SS316, SS304), chitsulo cha duplex, chitsulo cha carbon, Inconel®, Hastelloy®.

- Mpando:Zomatira zolimba kuchokera ku chitsulo kupita ku chitsulo kapena zinthu zophatikizika zopangidwa ndi laminated (monga graphite + chitsulo chosapanga dzimbiri).

- Disiki:Kawirikawiri amapakidwa ndi stellite kapena ceramic kuti asamavutike ndi kukanda.

Mikhalidwe Yogwirira Ntchito

- Kuchuluka kwa Kutentha:-196°C mpaka 850°C (-320°F mpaka 1,562°F).

- Zailesi:Zimagwirizana ndi nthunzi, ma hydrocarbon, mankhwala owononga, ndi madzi a cryogenic.

- Makampani:Mafuta ndi gasi, kupanga magetsi, kukonza mankhwala, LNG, ndi za m'madzi.

Ubwino wa Ma Valves a Gulugufe Osagwiritsidwa Ntchito Patatu

1. Kutaya Kosakwanira:Kapangidwe ka mipando yachitsulo kakugwirizana ndi ISO 5208 Leakage Class A (yolimba ngati thovu).

2. Moyo Wautali wa Utumiki:Kusakangana kumatsimikizira kuti zinthu sizingawonongeke kwambiri, ngakhale zitachitika maulendo ambirimbiri.

3. Kusamalira Kochepa:Sipafunika mafuta odzola kapena kusintha mpando nthawi zonse.

4. Kusinthasintha:Yosinthika kutentha kwambiri, kupsinjika, ndi zinthu zowononga.

Mapulogalamu

- Malo Oyeretsera Mafuta:Kupatula ndi kulamulira mafuta osakonzedwa, gasi, ndi zinthu zoyengedwa.

- Malo Opangira Mphamvu:Kupatula nthunzi mu ma turbine ndi ma boiler.

- Zomera Zamankhwala:Kuthana ndi ma acid, alkali, ndi madzi amphamvu.

- Machitidwe a Cryogenic:Kusungira ndi kunyamula LNG.

Kutsatira Malamulo ndi Ziphaso

- Miyezo:API 609, ASME B16.34, ISO 5752.

- Kapangidwe Kotetezeka Pamoto:Kutsatira malamuloAPI 607/API 6FAkwa ntchito zosagwira moto.

Valavu ya gulugufe ya triple offset imaphatikiza uinjiniya wolondola ndi zipangizo zolimba kuti ipereke kudalirika kosayerekezeka pazochitika zofunika kwambiri zamafakitale. Kapangidwe kake kapamwamba kamathetsa zofooka za mavavu achikhalidwe, zomwe zimapangitsa kuti ikhale chisankho chokondedwa pamakina amakono ogwira ntchito bwino.
