Valavu ya Gulugufe Yofewa Yotsekera Flange Yachiwiri Yokhala ndi Eccentric (Mtundu Wouma wa Shaft)

Tanthauzo la Zamalonda

Zinthu Zofunika Kwambiri Pakapangidwe ka Kapangidwe

1. Kapangidwe Kawiri Kosiyanasiyana
   • Kusazindikira Kwambiri: KusazindikiravalavuMzere wa shaft umachotsedwa pakati pa diski, zomwe zimachepetsa kukangana panthawi yotsegula/kutseka ndikuchepetsa kuwonongeka kwa malo otsekera.
   • Kugwirizana Kwachiwiri: Shaft imasiyana kwambiri ndi mzere wapakati wa payipi, zomwe zimapangitsa kuti "kulumikiza" kukhale kothandiza kwambiri pakutseka diski ikatsekedwa.
   • Ubwino: Imapereka kudalirika kwabwino kwambiri pakutseka ndipo imawonjezera nthawi yogwirira ntchito poyerekeza ndi mapangidwe a single-eccentric kapena concentric.
2. Njira Yotsekera Yofewa
   • Vavu imagwiritsa ntchito mphete yofewa yotsekera (yomwe nthawi zambiri imapangidwa ndi EPDM, NBR, kapena PTFE) yomwe imayikidwa m'thupi la valavu kapena diski, kuonetsetsa kuti mpweya umakhala wotseka komanso kuti imagwirizana ndi zinthu zosiyanasiyana (monga madzi, mafuta, mpweya, ndi madzi osapsa).
   • Ubwino: Kutsika kwa kutayikira kwa madzi (kukwaniritsa miyezo ya API 598 kapena ISO 15848) komanso mphamvu yochepa yofunikira kuti igwire ntchito.
3. Kumanga Shaft Youma
   • Shaft imatsekedwa padera ndi njira yolumikizirana, zomwe zimaletsa kukhudzana mwachindunji ndi madzi. Kapangidwe kameneka kamachotsa njira zomwe zingatulukire kudzera mu shaft ndipo kamachepetsa zoopsa za dzimbiri, makamaka m'malo ovuta.
   • Gawo Lofunika: Zisindikizo zamtundu wa V (monga kulongedza kwa V kapena zisindikizo zamakina) zimaonetsetsa kuti palibe kutuluka kwa madzi m'chitsime.
4. Kulumikiza kwa Flange
   • Yopangidwa ndi ma flange interfaces okhazikika (monga ANSI, DIN, JIS) kuti ikhale yosavuta kuyika m'mapaipi. Kapangidwe ka flange kamapereka kukhazikika kwa kapangidwe kake ndipo kamathandiza kukonza mosavuta.

Mfundo Yogwirira Ntchito

• Kutsegula: Pamene shaft ikuzungulira,ziwiri-eccentricDisiki imasuntha kuchokera pamalo otsekedwa, pang'onopang'ono ikuchoka ku chisindikizo chofewa. Zosintha zachilendo zimachepetsa kupsinjika koyambirira kwa kukhudzana, zomwe zimapangitsa kuti ntchito ikhale yosalala komanso yotsika.
• Kutseka: Disiki imazungulira mmbuyo, ndipo mawonekedwe a double-eccentric geometry amapanga kutseka pang'onopang'ono. Zotsatira za wedding zimawonjezera kupsinjika pakati pa disiki ndi chisindikizo, zomwe zimapangitsa kuti zitseke bwino.
• Chidziwitso: Kapangidwe ka shaft youma kamatsimikizira kuti shaftyo isakhudzidwe ndi kutentha kwa media, kuthamanga, kapena kuwonongeka, zomwe zimapangitsa kuti ikhale yodalirika.

Mafotokozedwe Aukadaulo

• Kukonza Madzi: Madzi akumwa, madzi otayira, ndi zimbudzi (zimafunika kutsekedwa kwambiri kuti zigwirizane ndi miyezo yaukhondo).
• Makampani Opanga Mankhwala: Madzi, ma acid, ndi ma alkali owononga (mzere wouma umateteza ku kuukira kwa mankhwala).
• Machitidwe a HVAC: Mapaipi oziziritsa mpweya ndi otenthetsera (mphamvu yochepa yogwirira ntchito pafupipafupi).
• Mafuta ndi Gasi: Zinthu zosawononga monga mafuta, gasi, ndi zosungunulira (kutseka kodalirika pazochitika zofunika kwambiri).
• Chakudya ndi Zakumwa: Kugwiritsa ntchito ukhondo (zomatira zogwirizana ndi FDA zimaonetsetsa kuti zinthuzo ndi zotetezeka).

• Ubwino Woposa Ma Vavu Achikhalidwe

  • Kutseka Kwapamwamba: Zisindikizo zofewa zimachotsa kutayikira, zoyenera kugwiritsidwa ntchito zomwe zimafuna chitetezo cha chilengedwe kapena kuyera kwambiri.
  • Kugwiritsa Ntchito Mphamvu Moyenera: Kugwiritsa ntchito mphamvu zochepa kumachepetsa mphamvu zomwe zimafunika kuti magetsi ayambe kugwira ntchito, zomwe zimachepetsa ndalama zogwirira ntchito.
  • Kutalika kwa Nthawi: Kapangidwe kake ka mbali ziwiri kamachepetsa kuwonongeka, pomwe shaft youma imateteza ku dzimbiri, zomwe zimapangitsa kuti ntchitoyo ikhale yayitali.
  • Kusunga Malo: Kapangidwe kakang'ono poyerekeza ndi ma valve a chipata kapena a globe, abwino kwambiri poyika malo ochepa.

  Malangizo Okonza & Kukhazikitsa

  • Kukhazikitsa: Onetsetsani kuti ma flange ali molunjika ndipo ma bolt ali olimba mofanana kuti apewe kupsinjika pa thupi la valavu.
  • Kusamalira: Yendani nthawi zonse kuti muwone ngati chitseko chofewa chawonongeka ndipo chibwezeretseni ngati chawonongeka. Pakani mafuta pa shaft ndi actuator nthawi ndi nthawi kuti muwonetsetse kuti zikugwira ntchito bwino.
  • Kusungira: Sungani pamalo ouma, opanda fumbi ndi valavu yotseguka pang'ono kuti muchepetse kupsinjika pa chisindikizo.
  Valavu iyi imaphatikiza uinjiniya wapamwamba ndi kapangidwe kothandiza, kupereka njira yodalirika komanso yotsika mtengo yogwiritsira ntchito zosowa zamakono zowongolera kayendedwe ka madzi m'mafakitale. Kuti musinthe mwamakonda (monga kukweza zinthu kapena zokutira zapadera), chonde funsani wopanga.
