Kodi avalavu ya butterfly?
Vavu ya butterfly imatchedwa valavu ya butterfly chifukwa mawonekedwe ake amafanana ndi gulugufe.The actuator amatembenuza mbale ya valve 0-90 madigiri kuti atsegule ndi kutseka valavu, kapena kusintha mwachidule kuthamanga kwa kayendedwe kake.
Kodi avalavu ya mpira?
Ma valve a mpira amagwiritsidwanso ntchito m'mapaipi kuwongolera ma valve omwe amawongolera kutuluka kwamadzi.Nthawi zambiri amagwiritsa ntchito bwalo lomwe lili ndi bowo kuti azitha kuyendetsa madzimadzi, omwe amatha kudutsa kapena kutsekeka pamene gawolo likuzungulira.
Monga zigawo zowongolera zamadzimadzi, mavavu agulugufe ndi mavavu a mpira amatha kugwiritsidwa ntchito kulumikiza ndikudula sing'anga mupaipi.Kodi pali kusiyana kotani, ubwino ndi kuipa kwake?M'munsimu tikuusanthula kuchokera ku kamangidwe, kuchuluka kwa ntchito, ndi zofunikira zosindikizira.
1. Kapangidwe ndi mfundo
- Kutsegula ndi kutseka kwa valve ya butterfly, mbale ya valve, monga dzina limatanthawuzira, ndi chidutswa chopangidwa ndi mbale chokhala ndi makulidwe enaake, pamene gawo lotsegula ndi lotseka la valve ya mpira ndi sphere.
- Ma valve a butterfly ndi osavuta komanso amakhala ndi mawonekedwe ophatikizika, motero amakhala opepuka;pamene ma valve a mpira ali ndi thupi lalitali ndipo amafuna malo okulirapo potsegula ndi kutseka.Amakonda kukhala akuluakulu komanso olemera.
- Vavu yagulugufe ikatseguka, mbale ya vavu imazungulira motsatana ndi njira yolowera, zomwe zimapangitsa kuyenda mopanda malire.Pamene valavu gulugufe chatsekedwa, valavu mbale ndi perpendicular kwa malangizo a sing'anga otaya, motero kwathunthu kutsekereza otaya.
- Pamene valavu ya mpira yodzaza ndi yotseguka, mabowowo amagwirizana ndi chitoliro, zomwe zimalola madzi kudutsa.Ndipo ikatsekedwa, mpirawo umazungulira madigiri 90, kutsekereza kwathunthu kutuluka.Valavu yodzaza ndi mpira imachepetsa kutsika kwamphamvu.
2. Kuchuluka kwa ntchito
- Mavavu agulugufe angagwiritsidwe ntchito panjira ziwiri zokha;mavavu a mpira amathanso kugwiritsidwa ntchito ngati ma diverters atatu kuphatikiza njira ziwiri.
- Mavavu agulugufe ndi oyenera kuyatsa/kuzimitsa kwa mapaipi otsika kwambiri;mavavu a mpira angagwiritsidwe ntchito poyendetsa bwino kuthamanga kwapamwamba pa kutentha ndi kupanikizika.
- Ma valve a butterfly amagwiritsidwa ntchito kwambiri pochiza zimbudzi, kukonza chakudya, machitidwe a HVAC, makina owongolera mpweya ndi madera ena;mavavu mpira zimagwiritsa ntchito mafuta, gasi, mafakitale mankhwala, zitsulo, mphamvu yamagetsi ndi minda ina mafakitale.
3. Kusindikiza
- Mavavu agulugufe osindikizira mofewa amadalira mipando ya valve zotanuka monga mphira kapena PTFE kuti apange chisindikizo pofinya mozungulira valavu.Pali mwayi wina woti chisindikizochi chidzawonongeka pakapita nthawi, zomwe zingayambitse kutayikira.
- Ma valve a mpira nthawi zambiri amakhala ndi zisindikizo zachitsulo kapena zitsulo kapena zofewa zomwe zimapereka chisindikizo chodalirika ngakhale mutagwiritsa ntchito nthawi yayitali.
Mwachidule, ma valve a butterfly ndi ma valves a mpira aliyense ali ndi ubwino wake ndi zovuta zake, ndipo valavu iti yomwe ingasankhe imadalira zochitika ndi zofunikira zomwe zimagwiritsidwa ntchito.
ZFA Valve Company ndi fakitale yomwe imagwira ntchito yopanga ma valve agulugufe osiyanasiyana.Ngati muli ndi mafunso, chonde omasuka kulankhula nafe.
