Valavu ya butterfly ya Taike imatha kugawidwa mu valavu ya butterfly ya pneumatic, valavu ya butterfly yamagetsi, valavu ya butterfly, ndi zina zotero. kutseka, ndi kuwongolera njira yamadzimadzi. Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera. Mu cylindrical channel ya gulugufe valavu thupi, chimbale zooneka gulugufe mbale amazungulira mozungulira olamulira, ndi kasinthasintha ngodya pakati 0 ° ndi 90 °. Kuzungulira kukafika 90 °, valavu imatsegulidwa kwathunthu. Valavu ya butterfly, yomwe imadziwikanso kuti flap valve, ndi njira yosavuta yowongolera valavu ndipo itha kugwiritsidwanso ntchito posinthira kuwongolera kwapaipi yotsika. Vavu ya gulugufe (Chingerezi: valavu ya butterfly) imatanthawuza mtundu wa vavu pomwe mbali yotsekera (disiki kapena disc) ndi chimbale chomwe chimazungulira mozungulira valavu kuti chitseguke ndi kutseka. Imagwira makamaka ngati valavu yotsekera komanso yopumira pamapaipi. Mbali ya gulugufe yotsegula ndi kutseka ndi mbale yagulugufe yooneka ngati chimbale yomwe imazungulira mozungulira mkati mwa thupi la valve kuti ikwaniritse cholinga chotsegula, kutseka kapena kusintha. Vavu yagulugufe nthawi zambiri imakhala yosakwana 90 ° kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, ndipo valavu yagulugufe ndi tsinde sizikhala ndi luso lodzitsekera. Kuti muyike mbale ya agulugufe, chotsitsa cha mphutsi chiyenera kuikidwa pa tsinde la agulugufe. Kugwiritsa ntchito makina ochepetsera nyongolotsi sikumangopangitsa kuti mbale yagulugufe ikhale ndi mphamvu yodzitsekera yokha ndikuyimitsa pamalo aliwonse, komanso imathandizira magwiridwe antchito a valve. Makhalidwe a ma valve agulugufe akumafakitale ndi kukana kutentha kwambiri, kuthamanga kwambiri, kutalika kwadzidzidzi, thupi la carbon steel, ndi mphete yachitsulo m'malo mwa mphete ya mphira yosindikizira mbale. Mavavu akuluakulu agulugufe omwe amatentha kwambiri amapangidwa ndi mbale zowotcherera zitsulo ndipo amagwiritsidwa ntchito makamaka popanga ma ducts a gasi wapakatikati ndi mapaipi amafuta.
Mavavu agulugufe atha kugawidwa m'magulu amtundu wa offset, mtundu wa mbale, mtundu wamba, ndi mtundu wa lever malinga ndi mawonekedwe awo. Malingana ndi mawonekedwe osindikizira, akhoza kugawidwa m'magulu awiri: osindikizidwa komanso osindikizidwa mwamphamvu. Mtundu wosindikiza wofewa nthawi zambiri umagwiritsa ntchito kusindikiza mphete za rabara, pomwe mtundu wosindikiza wolimba nthawi zambiri umagwiritsa ntchito kusindikiza mphete zachitsulo. Malinga ndi mtundu wa kugwirizana, izo zikhoza kugawidwa mu flange kugwirizana ndi yopyapyala kugwirizana; Malinga ndi njira yotumizira, imatha kugawidwa m'mitundu ingapo: yamanja, yotumiza zida, pneumatic, hydraulic, ndi magetsi.
1, Ubwino wa Mavavu a Gulugufe
1. Kutsegula ndi kutseka kwachangu komanso kofulumira, kupulumutsa ntchito, kutsika kwamadzimadzi, ndipo kumatha kugwiritsidwa ntchito pafupipafupi.
2. Mapangidwe osavuta, kukula kochepa, ndi kulemera kochepa.
3. Imatha kunyamula matope ndikusunga madzi ochepa pakamwa pa payipi.
4. Pansi pa kupanikizika kochepa, kusindikiza bwino kungapezeke.
5. Kuchita bwino kokonzekera bwino.
2, Kuipa kwa Mavavu a Gulugufe
1. Kuthamanga kwa ntchito ndi kutentha kumakhala kochepa.
2. Kusasindikiza bwino.
3, Kukhazikitsa ndi kukonza mavavu agulugufe
1. Pakuyika, diski ya valve iyenera kuyimitsidwa pamalo otsekedwa.
2. Malo otsegulira ayenera kutsimikiziridwa molingana ndi kuzungulira kwa mbale ya butterfly.
3. Mavavu agulugufe okhala ndi ma bypass valves ayenera kutsegulidwa asanatsegule.
4. Kuyika kuyenera kuchitidwa molingana ndi malangizo a wopanga, ndipo ma valve olemera a butterfly ayenera kukhala ndi maziko olimba.
5. Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera. Mu cylindrical channel ya gulugufe valavu thupi, chimbale zooneka gulugufe mbale amazungulira mozungulira olamulira, ndi kasinthasintha ngodya pakati 0 ° ndi 90 °. Kuzungulira kukafika 90 °, valavu imatsegulidwa kwathunthu.
6. Ngati valavu ya butterfly ikufunika kuti ikhale yothamanga, chinthu chachikulu ndikusankha kukula koyenera ndi mtundu wa valve. Kapangidwe ka mavavu agulugufe ndi oyenera kupanga mavavu akulu akulu akulu. Mavavu agulugufe samangogwiritsidwa ntchito kwambiri mumafuta, gasi, mankhwala, mankhwala amadzi ndi mafakitale ena wamba, komanso amagwiritsidwa ntchito m'madzi ozizira a malo opangira magetsi.
7. Pali mavavu agulugufe awiri omwe amagwiritsidwa ntchito kwambiri: valavu yagulugufe yamtundu wa wafer ndi valavu ya butterfly yamtundu wa flange. Valavu yagulugufe yamtundu wa wafer ndi valavu yomwe imalumikizidwa pakati pa mapaipi awiri opangira mabawuti okhala ndi mitu iwiri. Valavu yagulugufe yamtundu wa flange ndi valavu yokhala ndi flange, ndipo ma flanges kumapeto kwa valavu amalumikizidwa ndi payipi ya payipi pogwiritsa ntchito mabawuti.
8. Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera. Mu cylindrical channel ya gulugufe valavu thupi, chimbale zooneka gulugufe mbale amazungulira mozungulira olamulira, ndi kasinthasintha ngodya pakati 0 ° ndi 90 °. Kuzungulira kukafika 90 °, valavu imatsegulidwa kwathunthu.
