Groove Flanged Butterfly Valve

Vavu ya butterfly ndi mtundu wa valavu yomwe imagwiritsa ntchito magawo otsegulira ndi kutseka amtundu wa disc kuti atembenuke cham'mbuyo pafupifupi 90 ° kuti atsegule, kutseka kapena kusintha kayendedwe ka sing'anga.Valve ya butterfly sikuti imakhala ndi mawonekedwe osavuta, kukula kochepa, kulemera kochepa, kugwiritsa ntchito zinthu zochepa, kukula kwazing'ono, makina ang'onoang'ono oyendetsa galimoto, ntchito yosavuta komanso yofulumira, komanso imakhala ndi ntchito yabwino yoyendetsera kayendetsedwe kake komanso kutseka ndi kusindikiza zizindikiro panthawi yomweyo.Ma valve a butterfly amagwiritsidwa ntchito kwambiri.

Pogwiritsa ntchito mphira wosamva mankhwala pamavavu agulugufe, magwiridwe antchito a agulugufe apita patsogolo.Popeza mphira wopangidwa ndi mphira uli ndi mikhalidwe ya kukana dzimbiri, kukana kukokoloka, kukula kokhazikika, kukhazikika bwino, kupanga kosavuta, komanso kutsika mtengo, mphira wopangidwa ndi zinthu zosiyanasiyana ukhoza kusankhidwa malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito kuti ukwaniritse momwe ma valve agulugufe amagwirira ntchito.

Chifukwa polytetrafluoroethylene (PTFE) ili ndi kukana kwamphamvu kwa dzimbiri, kugwira ntchito mokhazikika, kosavuta kukalamba, kocheperako kocheperako, kosavuta kupanga, kukula kokhazikika, komanso magwiridwe antchito ake onse amatha kupitilizidwa podzaza ndi kuwonjezera zida zoyenera kuti apeze mphamvu ndi mikangano.Zida zosindikizira valavu za butterfly zokhala ndi koyefisi yotsika zimagonjetsa malire a labala opangira.Chifukwa chake, zida zapamwamba zama polymer zomwe zimayimiridwa ndi polytetrafluoroethylene ndi kudzaza kwawo zida zosinthidwa zakhala zikugwiritsidwa ntchito kwambiri mu ma valve agulugufe, kuti magwiridwe antchito a agulugufe apite patsogolo.Zasinthidwanso, ndipo valavu yagulugufe yokhala ndi kutentha kwakukulu ndi kupanikizika, ntchito yodalirika yosindikiza komanso moyo wautali wautumiki wapangidwa.

Pofuna kukwaniritsa zofunikira za mafakitale monga kutentha kwakukulu ndi kutsika, kukokoloka kwamphamvu, ndi moyo wautali, ma valve a butterfly osindikizidwa ndi zitsulo apangidwa kwambiri.Ndi kugwiritsa ntchito kukana kutentha kwambiri, kukana kutentha kwapansi, kukana kwamphamvu kwa dzimbiri, kukana kukokoloka kwamphamvu, ndi zida zamphamvu za aloyi mu mavavu agulugufe, mavavu agulugufe osindikizidwa zitsulo akhala akugwiritsidwa ntchito kwambiri m'mafakitale monga kutentha kwambiri ndi kutsika, kolimba. kukokoloka, ndi moyo wautali.Mavavu agulugufe okhala ndi mainchesi (9 ~ 750 mm), kuthamanga kwambiri (42.0 MPa), komanso kutentha kwakukulu (-196 - 606 ° C) awonekera.

Vavu yagulugufe ikatsegulidwa kwathunthu, imakhala ndi kukana koyenda pang'ono.Pamene kutsegula kuli pakati pa 15 ° ~ 70 °, kungathenso kulamulira kayendedwe kake, kotero m'munda wa malamulo akuluakulu, kugwiritsa ntchito ma valve agulugufe kumakhala kofala kwambiri.

Popeza mayendedwe a gulugufe mbale akupukuta, mavavu agulugufe ambiri angagwiritsidwe ntchito TV ndi inaimitsidwa olimba particles.Kutengera mphamvu ya chisindikizocho, itha kugwiritsidwanso ntchito ngati powdery ndi granular media.

Ma valve a butterfly ndi oyenera kuwongolera kayendedwe kake.Popeza kuthamanga kwa valavu ya gulugufe mu chitoliro kumakhala kwakukulu, pafupifupi katatu kuposa valavu ya chipata, posankha valavu ya butterfly, chikoka cha kutayika kwa payipi pamapaipi chiyenera kuganiziridwa bwino, ndi mphamvu ya Mbalame ya agulugufe kuti ipirire kupsinjika kwa mapaipi apakati ikatsekedwa iyeneranso kuganiziridwa..Kuonjezera apo, kuchepetsa kutentha kwa ntchito ya zinthu zotanuka mpando pa kutentha kwakukulu kuyeneranso kuganiziridwa.

Kutalika kwa dongosolo ndi kutalika kwa valavu ya gulugufe ndizochepa, kutsegula ndi kutseka kufulumira, ndipo kumakhala ndi makhalidwe abwino olamulira madzimadzi.Mfundo yokhazikika ya valavu ya gulugufe ndiyo yabwino kwambiri popanga mavavu akuluakulu.Pamene valavu ya butterfly ikufunika kuti igwiritsidwe ntchito poyendetsa kayendetsedwe kake, chinthu chofunika kwambiri ndikusankha molondola ndondomeko ndi mtundu wa valavu ya butterfly kuti igwire bwino ntchito.

Nthawi zambiri, ma valve agulugufe akulimbikitsidwa kuti azigwedeza, kuwongolera malamulo ndi matope pomwe kutalika kwake kwafupipafupi, kutsegula ndi kutseka kwachangu, komanso kutsika kwapakati (kusiyana kochepa) kumafunika.Ma valve a butterfly amatha kusankhidwa kuti azitha kusintha magawo awiri, njira zochepetsera m'mimba mwake, phokoso lochepa, cavitation ndi vaporization, kutayikira pang'ono kumlengalenga, ndi media abrasive.Kusintha kwa throttle pansi pamikhalidwe yapadera yogwirira ntchito, kapena mikhalidwe yogwirira ntchito yomwe imafuna kusindikiza mwamphamvu, kuvala kwambiri, kutentha kochepa (cryogenic) ndi zina zotero.
