Chabwino n'chiti, Vavu yoyang'ana Wafer ndi valavu yoyang'ana flange? Yankho lake ndi ma valve owonetsetsa a flanged, chifukwa ma valve otsekemera amatha kupirira kupanikizika kwakukulu ndipo amagwiritsidwa ntchito kwambiri. Ubwino waukulu wa ma valve owunikira ndi mtengo wawo wotsika komanso kukula kochepa. Koma sitingathe kufanizitsa mitundu iwiriyi ya ma valve, chifukwa mitundu iwiri ya ma valve ndi yosiyana kwambiri, ndipo kusankha valavu yoyenera pansi pa ntchito yoyenera kungathe kugwira ntchito ya valve. Chovala choyang'ana chawafa ndi valavu yoyang'ana flange Yankho lake ndi ma valve otsegula, chifukwa ma valve otsegula amatha kupirira kupanikizika kwakukulu ndipo amagwiritsidwa ntchito kwambiri. Ubwino waukulu wa ma valve owunikira ndi mtengo wawo wotsika komanso kukula kochepa. Koma sitingathe kufanizitsa mitundu iwiriyi ya ma check valves, chifukwa mitundu iwiri ya ma valve ndi yosiyana kwambiri, ndipo kusankha valavu yoyenera pansi pa ntchito yoyenera kungathe kugwira ntchito ya valve.
Valve yoyang'ana wafer kapena valavu yoyang'ana flange
Kusiyana pakati pa valavu yoyang'ana valavu ndi valavu ya flange ndi:
- Kugwiritsa ntchito nyundo yamadzi ndikosiyana:
The valve yoyang'ana pansi ndi yaying'ono kukula kwake, ili ndi sitiroko yachidule ya disc, ndipo imathandizidwa ndi kasupe kutseka valavu.
- Kuyerekeza kukula ndi kulemera kwake:
Chovala choyang'ana chofufumitsa chimakhala ndi mawonekedwe afupikitsa, kukula kwazing'ono ndi kulemera kwake, zomwe zimabweretsa mwayi waukulu pakuyika, kusamalira, kusungirako ndi kukonza mapaipi a valve, ndipo amatha kusunga zipangizo zambiri ndikuchepetsa mtengo; valavu ya flange Mapangidwe a valve ndi aatali, ochulukirapo komanso olemera.
- Kugwiritsa ntchito madzimadzi kumasiyana:
Kukaniza kwa valve yoyang'ana kavalo ndi kakang'ono, ndipo mphamvu yamadzimadzi yokana ξ ndi 2.6 ~ 2.7. Ndi kuwonjezeka kwa valavu ya valve, kuchuluka kwa madzimadzi kumachepa; valavu yoyang'ana flange ndi yaying'ono, ndipo kukana kwamadzimadzi ξ ndi 1.3 ~ 3, koma pansi pa zovuta zochepa, diski ya valve sichitha kutsegulidwa kwathunthu, ndipo kukana kwamadzimadzi kumakhala kwakukulu. Kukaniza kwamadzimadzi kumawonjezeka ndi kuwonjezeka kwa ma valve awiri.
- Njira yoyika ndi yosiyana:
Valavu yoyang'ana wafer imatha kukhazikitsidwa molunjika kapena molunjika, ndipo kulemera kwake ndi kopepuka, kotero sikoyenera kukhazikitsa chithandizo cha valve; kuyika kopingasa kwa valavu ya flange ndi valavu yayikulu m'mimba mwake ndi yolemetsa ndipo ikufunika kukhazikitsa chithandizo.
- Kuthamanga kotsegulira ndi kosiyana:
Kutsegula kwa valve yoyang'ana kachidutswa kakang'ono kwambiri, ndipo diski ikhoza kutsegulidwa kwathunthu pansi pa kusiyana kochepa; kutsegulira kwa valve ya flange check valve ndi yaikulu, ndipo diski ikhoza kutsegulidwa kwathunthu pansi pa kusiyana kwakukulu.
- Kudalirika kwa valve ndi kosiyana:
Chovala chowongolera chofufumitsa ndi dongosolo lonse, losavuta komanso lophatikizana, mphamvu yowonongeka ndi yaying'ono pamene valavu yatsekedwa, kuthamanga kwa nyundo yamadzi kumakhala kochepa, moyo wa valve ndi wautali, ndipo kudalirika kuli kwakukulu; mphamvu yaikulu yamphamvu ndi kuthamanga kwa nyundo ya madzi pamene valavu ya flange yatsekedwa ndi yosavuta Kuwononga valavu.
