Kodi Vavu ya Mpira Ndi Chiyani

Onani Chithunzi Chachikulu
Palinso kufunikira kokulirapo kwa mavavu a mpira pamene dziko likufunafuna njira zina zowonjezera mphamvu.Kupatula ku China, ma valve a mpira amapezekanso ku India.Palibe kutsutsa kufunikira kwa ma valve oterowo pamakina aliwonse opanga mapaipi a mafakitale.Koma, zambiri ziyenera kuphunzitsidwa za mavavu a mpira, ndipo muyenera kuzidziwa musanagwiritse ntchito.Nkhaniyi ikuthandizani kumvetsetsa mavavu a mpira kuti mudziwe ngati ali oyenera kugwiritsa ntchito.

Zomwe Muyenera Kudziwa Zokhudza Ma Valves A Mpira

Mmodzi mwa ma valve omwe amagwiritsidwa ntchito kwambiri m'mafakitale, ma valve a mpira nthawi zambiri amagwiritsidwa ntchito potseka zolimba.Valavu ya mpira idatenga dzina lake kuchokera ku gawo lozungulira lomwe limalola kuti media idutse ikatsegula kapena kutsekereza ikatsekedwa.Awa ndi mamembala a banja la quarter-turn la ma valve a mafakitale.

Valavu ya mpira nthawi zambiri imagwiritsidwa ntchito m'mafakitale ambiri kotero sizosadabwitsa kupeza kuti kufunikira kwake ndikokwera.Masiku ano, mungapeze zapamwamba zopangidwa ku China mavavu a mpira kapena ma valve opangidwa ku India.

Common Ball Valve Features

Mitundu yambiri ya valavu ya mpira imagawana zomwe zanenedwa pansipa:
# Swing Check - izi zimalepheretsa kubweza kwa media
# Vavu imayima - izi zimangotembenuza ma degree 90 okha
# Anti-static - izi zimalepheretsa kukhazikika kwamagetsi komwe kungayambitse zopsereza
# Zotetezedwa pamoto - mpando wachiwiri wachitsulo umamangidwa kuti ukhale ngati mipando yowonjezera pazigawo zotentha kwambiri.

Ubwino ndi Kuipa kwa Vavu ya Mpira

Ma valve a mpira ndi abwino kugwiritsa ntchito pamene dongosolo likufuna kutsegula ndi kutseka mwamsanga.Izi ndizopindulitsanso pamagwiritsidwe ntchito pomwe zimafunikira chisindikizo cholimba popanda kuganizira kupanikizika kwakukulu kwamkati.
Komabe, ma valve a mpira ali ndi mphamvu zochepa zopunthira.M'malo mwake, izi sizovomerezeka pakuwongolera ma media.Mavavu a mpira amakhala ndi mipando yowonekera pang'ono, yomwe imatha kukokoloka mwachangu akagwiritsidwa ntchito.Izi zimakhalanso zovuta kutsegula mofulumira komanso pamanja pamene kupanikizika kuli kwakukulu.

Zida za Common Ball Valve

Ma valve a mpira amabwera muzinthu zosiyanasiyana.Kutengera mtundu wa ntchito, mavavu a mpira nthawi zambiri amapangidwa kapena kuponyedwa pogwiritsa ntchito chitsulo, chitsulo chosapanga dzimbiri, ndi zitsulo zina.Mipando ya valve ya mpira imatha kupangidwa ndi zinthu za elastomeric monga PTFE kapena zitsulo, nthawi zambiri zitsulo zosapanga dzimbiri.

Zigawo za Ball Valve

Ngakhale pali mitundu ingapo ya valavu ya mpira, pali zigawo zisanu zomwe zimapezeka m'mavavu onse a mpira monga zikuwonekera pa chithunzi pansipa:

# Thupi
Thupi limagwira zigawo zonse pamodzi
# Mpando
Mpando umasindikiza valavu panthawi yotseka
#Mpira
Mpira umalola kapena kutsekereza njira ya media.
# Wothandizira
The actuator kapena lever amasuntha mpira kuti womaliza atsegule kapena kutseka.
# Tsinde
Tsinde limagwirizanitsa mulingo ndi mpira.

Zithunzi za Ball Valve

Nthawi zambiri, ma valve a mpira amakhala ndi madoko awiri.Koma pobwera ntchito zatsopano, ma valve a mpira amatha kukhala ndi madoko anayi.Izi nthawi zambiri zimatchedwa ma valve a njira ziwiri, njira zitatu kapena zinayi.Valavu yanjira zitatu imatha kukhala ndi kasinthidwe ka L kapena T-kusintha.

Mpira Valve Ntchito Njira

Disiki ya mpira imatsegulidwa kapena kutsekedwa potembenuza chowongolera kotala kapena madigiri 90.Pamene lever ikufanana ndi kutuluka kwa media, valavu imalola kuti chotsatiracho chidutse.Pamene lever imakhala perpendicular kwa kuyenda kwa media, valavu imalepheretsa kutuluka kwa chomaliza.

Magawo a Ball Valve

Ma valve a mpira amagawidwa m'njira zingapo.Mutha kukumana ndi magulu a valve potengera kuchuluka kwa zigawo kapena mtundu wa ma valve a mpira.

Kutengera Nyumba

Mutha kugawa ma valve a mpira kutengera kuchuluka kwa zigawo zomwe matupi awo ali nazo.Chotsika mtengo kwambiri pakati pa atatuwo, valavu yamtundu umodzi imapangidwa ndi chitsulo chimodzi chopangidwa ndi chitsulo.Izi sizingathetsedwe poyeretsa kapena kukonza.Ma valve amtundu umodzi ndi oyenera kugwiritsa ntchito zochepetsera zochepa.

Kumbali ina, valavu yamagulu awiri a mpira amapangidwa ndi zidutswa ziwiri zogwirizanitsidwa ndi ulusi.Mtundu uwu uyenera kuchotsedwa kwathunthu ku payipi pamene ukutsukidwa kapena kusinthidwa.Potsirizira pake, zigawo za valavu ya mpira wa zidutswa zitatu zimagwirizanitsidwa ndi ma bolts.Kukonzekera kungathe kuchitidwa pa valavu ngakhale ikadali yolumikizidwa ku payipi.

Kutengera Chimbale Design

Mapangidwe a mpira ndi gulu lalikulu la mavavu a mpira.Amatchulidwa moyenerera chifukwa mpirawo umayimitsidwa pamwamba pa tsinde, valavu ya mpira woyandama ndiyo mapangidwe ambiri a gululi.Pamene ikutseka, mpirawo ukupita kumalo otsegulira pansi.Kuthamanga kwamphamvu kumathandiza kusindikiza valve mwamphamvu.

Kumbali ina, mapangidwe a mpira wa trunnion amapangidwa mokhazikika ndi ma trunnions omwe ali pansi pa mpirawo.Njira yabwino kwambiri yogwiritsira ntchito ma valve opangidwa ndi trunnion ndi omwe ali ndi mipata yayikulu ndi mizere yothamanga kwambiri, nthawi zambiri kuposa 30 bar.

Kutengera Pipe Diameter

Mavavu a mpira amathanso kugawidwa potengera kukula kwa kulumikizana molingana ndi kukula kwa mapaipi.Valavu yocheperako imatanthawuza kuti makulidwe a valavu ndi kukula kocheperako kuposa mapaipi.Izi zimabweretsa kuchepa kwapang'onopang'ono.Mavavu amtundu umodzi nthawi zambiri amakhala ndi mtundu wocheperako.

Mitundu yamitundu yonse imakhala ndi mainchesi ofanana ndi a mapaipi.Ubwino wamtunduwu umaphatikizapo kusataya kupsinjika komanso kuyeretsa kosavuta.Mitundu yodzaza ndi yokwera mtengo kwambiri chifukwa cha kukula kwa valve.Pomaliza, Mtundu wooneka ngati V uli ndi dzenje lokhala ngati V lomwe limathandizira kuwongolera kwamadzimadzi nthawi zonse valavu ikatsegulidwa.

Mapulogalamu a Mpira Vavu

Ma valve a mpira nthawi zambiri amapezeka m'mitundu yosiyanasiyana.Nthawi zambiri, mumawapeza mumayendedwe oyenda pazombo, zowononga ndi ntchito zoteteza moto.Izi sizimagwiritsidwa ntchito ngati kuipitsidwa ndi vuto monga zomwe zili m'magawo opangira chakudya.Mavavu a mpira ndi ovuta kuyeretsa.

Mwachidule

Ma valve a mpira akusintha limodzi ndi mafakitale omwe amalumikizidwa nawo.Pokhala ogula, kudziphunzitsa nokha za zomwe valavu ya mpira ndiyofunikira.
