Mavavu agulugufe amatha kugawidwa mu mavavu agulugufe a 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 kuzungulira olamulira, ndi kasinthasintha ngodya ndi pakati 0 ° ndi 90 °.Pamene kuzungulira kufika 90 °, valavu imatsegulidwa kwathunthu.Valavu ya butterfly, yomwe imatchedwanso valavu, ndi mtundu wa valavu yowongolera yokhala ndi mawonekedwe osavuta.Itha kugwiritsidwanso ntchito poyang'anira pawongoleretsa wamapaipi otsika.Vavu ya butterfly imatanthawuza mtundu wa valavu yomwe mbali yake yotsekera (disiki kapena mbale ya butterfly) ndi chimbale, chomwe chimazungulira kuzungulira valavu kuti chitsegulidwe 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 mbale ya agulugufe ikhazikike, patsinde la agulugufe muyike 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 valavu.Valavu ya butterfly ya mafakitale imadziwika ndi kukana kutentha kwambiri, kuthamanga kwapamwamba, kuthamanga kwakukulu, m'mimba mwake yaikulu ya 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 wambale wokhazikika ndi mtundu wa lever malinga ndi kapangidwe kake.Malinga ndi mawonekedwe osindikizira, amatha kugawidwa m'mitundu iwiri: mtundu wosindikizidwa kwambiri komanso wosindikizidwa molimba.Mtundu wa chisindikizo chofewa nthawi zambiri umagwiritsa ntchito mphete ya rabara, ndipo mtundu wa chisindikizo cholimba nthawi zambiri umagwiritsa ntchito mphete yachitsulo.Malinga ndi mtundu wa kugwirizana, izo zikhoza kugawidwa mu flange kugwirizana ndi yopyapyala kugwirizana;molingana ndi njira yotumizira, imatha kugawidwa m'mabuku, kutumizira zida, pneumatic, hydraulic ndi magetsi.
