Mavavu agulugufe amatha kugawidwa mu ma valve a butterfly pneumatic, ma valve agulugufe amagetsi, ma valve a butterfly, etc. Vavu ya butterfly ndi valve yomwe imagwiritsa ntchito mbale yagulugufe yozungulira ngati gawo lotsegula ndi lotseka ndikuzungulira ndi tsinde la valve kuti litsegule, kutseka ndi kusintha. njira yamadzimadzi.Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera.Mu cylindrical ndime ya gulugufe thupi valavu, mbale woboola pakati gulugufe mbale amazungulira mozungulira olamulira, ndi kasinthasintha ngodya ndi pakati 0 ° ndi 90 °.Pamene kuzungulira kufika 90 °, valavu imatsegulidwa kwathunthu.Valavu ya butterfly, yomwe imatchedwanso kuti flap valve, ndi mtundu wa valve yowongolera yokhala ndi mawonekedwe osavuta.Itha kugwiritsidwanso ntchito poletsa kuwongolera kwapaipi yapaipi yotsika.Vavu ya butterfly imatanthawuza mtundu wa valavu yomwe mbali yake yotsekera (disiki kapena mbale ya gulugufe) ndi chimbale, chomwe chimazungulira kuzungulira shaft ya valve kuti ikwaniritse kutsegula ndi kutseka.Amagwiritsidwa ntchito kwambiri podula ndi kugwedeza paipi.Mbali ya gulugufe yotsegula ndi kutseka ndi mbale ya butterfly yooneka ngati diski, yomwe imazungulira mozungulira muzitsulo zake mu thupi la valve kuti ikwaniritse cholinga chotsegula ndi kutseka kapena kusintha.Vavu yagulugufe nthawi zambiri imakhala yosakwana 90 ° kuchokera kutseguka mpaka kutsekedwa kwathunthu.Vavu yagulugufe ndi tsinde lagulugufe alibe luso lodzitsekera lokha.Kuti akhazikike mbale ya agulugufe, patsinde la agulugufe akhazikike chochepetsera giya ya nyongolotsi.Kugwiritsa ntchito makina ochepetsera nyongolotsi sikungangopangitsa kuti mbale yagulugufe ikhale ndi luso lodzitsekera, kupangitsa mbale yagulugufe kuyimitsa pamalo aliwonse, komanso kuwongolera magwiridwe antchito a valve.Valavu ya butterfly ya mafakitale imadziwika ndi kukana kutentha kwambiri, kuthamanga kwapamwamba, kuthamanga kwakukulu kwa valve, thupi la valve limapangidwa ndi carbon steel, ndipo mphete yosindikizira ya mbale ya valve imagwiritsa ntchito mphete yachitsulo m'malo mwa mphete ya rabara.Valavu yayikulu yotentha yagulugufe imapangidwa ndi kuwotcherera mbale zachitsulo, ndipo imagwiritsidwa ntchito kwambiri popanga ma ducts ndi mapaipi amafuta amtundu wotentha kwambiri.

Mavavu agulugufe amatha kugawidwa mumtundu wa mbale yosinthira, mtundu wa mbale yowongoka, mtundu wokhazikika wa mbale ndi mtundu wa lever malinga ndi kapangidwe kake.Malinga ndi mawonekedwe osindikizira, amatha kugawidwa m'mitundu iwiri: mtundu wosindikizidwa kwambiri komanso wosindikizidwa molimba.Chisindikizo chofewa nthawi zambiri chimagwiritsa ntchito mphete ya rabara, ndipo chisindikizo cholimba nthawi zambiri chimagwiritsa ntchito mphete yachitsulo.Malingana ndi mtundu wa kugwirizana, zikhoza kugawidwa mu kugwirizana kwa flange ndi kugwirizana kwa wafer;molingana ndi njira yotumizira, imatha kugawidwa m'mabuku, kutumizira zida, pneumatic, hydraulic ndi magetsi.
