1. Tanthauzo Lachikulu ndi Kapangidwe
Vavu yagulugufe yofewa yotsekera (yomwe imadziwikanso kuti "center-line butterfly valve") ndi valavu yozungulira yomwe imapangidwira kuyatsa kapena kuzimitsa kapena kuwongolera kayendedwe ka mapaipi. Zina zake zazikulu ndi izi:
Mapangidwe a Concentric: Tsinde la valve, disc, ndi mpando zimalumikizidwa pakatikati pa axis, kupanga mawonekedwe osavuta komanso ophatikizika.
Njira Yosindikizira Yofewa: Chisindikizo chosinthika cha elastomeric (mwachitsanzo, mphira, EPDM, NBR) chimaphatikizidwa mu thupi la valve kapena mpando, kupereka chisindikizo cholimba kuti chiteteze kutayikira.
Flanged Ends: Valavu ili ndi maulumikizidwe opindika, kulola kuyika kosavuta pamapaipi ogwirizana ndi miyezo monga ANSI, DIN, kapena JIS.
2.Zigawo Zofunikira
3. Mfundo Yogwira Ntchito
Malo Otsegula: Diski imazungulira 90° kuti agwirizane ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
Malo Otsekedwa: Chimbale chimazungulira kumbuyo kuti chikanikize chisindikizo chofewa, ndikupanga kutseka kolimba. Mapangidwe a concentric amadalira kusinthika kwa zotanuka kwa chisindikizo kuti akwaniritse kusindikiza, ndikupangitsa kuti ikhale yothandiza kwambiri pamagwiritsidwe ntchito otsika.
4. Mbali zazikulu ndi Ubwino wake
Kusindikiza Molimba: Zisindikizo zofewa zimapereka kukana kutayikira kwabwino, nthawi zambiri zimakumana ndi zolimba zolimba (mwachitsanzo, ANSI B16.104 Class VI, ISO 15848-1).
Low Torque Operation: Mapangidwe okhazikika komanso chisindikizo chosinthika amachepetsa kugundana, kulola kugwiritsa ntchito pamanja mosavuta kapena kugwiritsa ntchito ma actuators opepuka.
Ocheperako komanso Opepuka: Poyerekeza ndi mavavu a geti kapena globe, mavavu agulugufe omwe ali pakati ndi ang'onoang'ono komanso osavuta kuyika m'malo ochepa.
Zotsika mtengo: Mapangidwe osavuta komanso kugwiritsa ntchito zinthu zochepa kumapangitsa kuti zikhale zotsika mtengo pazofunikira zowongolera kuyenda.
Kugwirizana kwa Media: Yoyenera madzi, mpweya, mafuta, zamadzimadzi zosawononga, ndi media granular (zokhala ndi zokutira zosamva abrasion).
5. Mafotokozedwe Aukadaulo
Pressure Rating: Nthawi zambiri kutsika kwapakatikati (mwachitsanzo, PN6-PN16 / Gawo 125-Gawo 150).
Kutentha:
Ma elastomer wamba (mwachitsanzo, NR, EPDM): -10°C ku 90°C (14°F ku 194°F).
Zisindikizo zotentha kwambiri (mwachitsanzo, Viton®, PTFE): -20°C mpaka 150°C (-4°F ku 302°F).
Kutsata Miyezo:
Kupanga: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Kuyesa: API 598, (mayeso otuluka).
6. Mapulogalamu
Mavavu agulugufe okhazikika otsekera Chithunzi cha D341X-16Qamagwiritsidwa ntchito kwambiri mu:
Kapezekedwe ka Madzi ndi Ngalande: Njira zamadzi zamatauni, malo oyeretsera zimbudzi, ndi njira zothirira.
Ma HVAC Systems: Kuwongolera mpweya, madzi, kapena nthunzi potenthetsa, mpweya wabwino, ndi zowongolera mpweya.
Makampani a Chakudya ndi Chakumwa: Ntchito zaukhondo zokhala ndi zisindikizo zogwirizana ndi FDA (mwachitsanzo, EPDM yokhala ndi zokutira zamakalasi a chakudya).
Njira Zazikulu Zamakampani: Kugwira madzimadzi osawononga m'mafakitale, mapepala, ndi m'mafakitale amankhwala (kwa media media okha).
Kumanga kwa Marine ndi Zombo: Kuwongolera / kuzizimitsa m'madzi a m'nyanja kapena machitidwe a ballast (okhala ndi zida zolimbana ndi dzimbiri).
7. Zoperewera ndi Kuganizira
Kuchepetsa Kupanikizika ndi Kutentha: Sikoyenera kuthamanga kwambiri (mwachitsanzo,> PN16) kapena kugwiritsa ntchito kutentha kwambiri (mwachitsanzo, nthunzi pamwamba pa 150°C).
Kuopsa kwa dzimbiri: Zitsulo (monga matupi achitsulo) zimatha kuwononga m'malo ovuta; sinthani kukhala zitsulo zosapanga dzimbiri kapena zokutira pazovuta kwambiri.
Abrasive Media: Zisindikizo zofewa zimatha kuvala mwachangu ndi madzi odzaza ndi tinthu; ganizirani mavavu agulugufe osindikizira olimba kwambiri kapena zokutira zowonjezera zoteteza.
Kusankha kwa Actuator: Pama valve akulu akulu kapena kugwira ntchito pafupipafupi, gwiritsani ntchito ma pneumatic/hydraulic actuators kuti mupewe kutopa pamanja.
8. Kuyika ndi Kukonza
Kuyika:
Onetsetsani kuti ma flange alumikizidwa ndipo mabawuti amangiriridwa mofanana kuti asatayike.
Pewani kukhazikitsa valavu pansi pa kupsinjika kwambiri kwa mapaipi.
Kusamalira:
Yang'anani nthawi zonse chisindikizo kuti chivale kapena kusweka, makamaka pamapulogalamu apamwamba.
Mafuta tsinde ndi actuator nthawi ndi nthawi kuonetsetsa ntchito bwino.
Bwezerani chisindikizo ngati kutayikira kumachitika; mapangidwe ena amalola kuti chisindikizo chisinthidwe popanda kuchotsa valve paipi.
9. Maupangiri Osankha Ogulitsa ndi Zogulitsa
Chitsimikizo Chazinthu: Onetsetsani kuti zisindikizo zimakwaniritsa miyezo yamakampani (mwachitsanzo, FDA yazakudya, ATEX yamalo ophulika).
Zosintha Mwamakonda: Otsatsa ena amapereka zopangira zotsutsana ndi ma static, mawonekedwe otetezedwa ndi moto, kapena zokutira zapadera (mwachitsanzo, epoxy, PTFE) pazogwiritsa ntchito niche.
Mapeto
Mavavu agulugufe okhazikika otsekerandi njira yotsika mtengo, yodalirika yowongolera kuthamanga kwapakati pakatikati pamayendedwe osafunikira. Kuphweka kwawo, kusindikiza kolimba, komanso kukonza bwino kumawapangitsa kukhala chisankho chodziwika bwino m'madzi, HVAC, ndi machitidwe a mafakitale. Pamalo ofunikira kwambiri, kukwezera ku mapangidwe a eccentric kapena zida zamtengo wapatali kumalimbikitsidwa. Nthawi zonse fufuzani zamtundu wa media, momwe mungagwiritsire ntchito, ndi zofunikira kuti musankhe valavu yoyenera pazosowa zanu.
