Katunduyu amakankhira pansi-mmwamba madzimadzi, valavu imakhala ndi kapangidwe kambiri, ndipo limayikidwa pakati pa ma flanges awiri, ndipo kukula kwakung'ono ndi kunenepa kochepa.
AWambiri wapamwamba kwambiriili ndi ma dikisi awiri owoneka bwino oyikidwa pa shaft yolumikizidwa m'chipindacho. Kapangidwe kameneka kafupikira komwe kuli pakati pa mphamvu yokoka. Ntchito yomanga iyi imachepetsa kulemera kwa disc ndi 50% poyerekeza ndi ma swing-cheke-cheke chofanana. Chifukwa cha katundu wa masika, valavu imagwiranso mwachangu kuti mubwezere.
Kumanga kwapamwamba kwambiri kwa loberd-tobeppeight kumapangitsa mpando kusindikizidwa ndikuchita bwino.
Ntchito yayitali ya mtunda wautali wa gulugufe wawiriChongani valavuImalola kuti disc kuti itseguke ndikutseka popanda kuphwanya mpando, ndipo kasupe wachitanso pawokha kuti mutseke disc (DN150 ndi pamwambapa).
Chithandizo cha Hinged Christfer a GulugufeChongani valavuAmachepetsa mikangano ndikuchepetsa nyundo yamadzi ikachotsedwa mu disc (yokwezeka).
Poyerekeza ndi wambaSwing Check Valves,Wambiri wapamwamba kwambiriNtchito yomanga imakhala yamphamvu kwambiri, yopepuka, yaying'ono, yogwira mtima, komanso yotsika mtengo. Valavu iyi imakumana ndi muyeso wa API 594, kwa magawo ambiri, kukula kwa valavu iyi ndi 1/4 yokha ya valavu yam'mimba, ndipo kulemera kwake ndi 15% ya valavu yodutsa. Ndikosavuta kukhazikitsa pakati pa ma gasketi ndi chitoliro. Chifukwa ndikosavuta kusamalira ndipo zimangofuna mabatani amodzi okha, imapulumutsanso zigawo mukayika, kupulumutsa ndalama zonyamula ndi kukonzanso kwa tsiku ndi tsiku.
Valavu ya Flap Awiri-Flavil Plave ilinso ndi zinthu zomanga zapadera zomwe zimapangitsa kuti valavu ikhale yopanda tanthauzo. Izi zikuphatikiza kutseguka koyera, zodziyimira pawokha, zodziyimira pawokha za ma vallves ambiri, komanso njira zodziyimira pawokha. Zina mwazinthuzi sizipezeka ndi mavavu. Valavu yokhala ndi ma vate yoyera imatha kupangidwanso ndi ma Lugs, zipinda ziwiri ndi thupi lotalikirana.
Choyamba, njira yotsegulira ndi yotseka
Kugwiranso ntchito kawiri kumakhala ndi ma disc otalika (semi-disc) kuyimitsidwa pa pini yolumikizidwa yomwe ili yolumikizidwa pakatikati. Madziwo akayamba kuyenda, chimbacho chimatseguka ndi mphamvu (f) kutsatira pakatikati pa chikhomo. Mphamvu yothandizira masika (FS) imagwiritsidwa ntchito pamalo osakhazikika pakati pa disc, ndikupangitsa kuti chimbudzi chizitseguka kaye. Izi zimapewa mikangano pachipinda chosindikizira chomwe disc imatsegulidwa m'matangu akuluakulu achizolowezi, kuchotsa kuvala ndi kung'amba ndikung'amba.
Kuthamanga kochepa kumachepetsa, zingwe zamasamba zimangotulutsa zokha, ndikupangitsa disc kuti itseke ndikuyenda pafupi ndi mpando wa thupi, kuchepetsa mtunda ndi nthawi yotseka. Madzi akatuluka mmbuyo, pang'onopang'ono amasunthira pafupi ndi mpando wa thupi, ndipo kuyankha kwamphamvu kwa valavu kumatha ntchito kwambiri, kuchepetsa mphamvu yamadzi osayenera.
Mukatseka, zochita za kasupe zimayambitsa pamwamba pa disc kuti mutseke kaye, kupewa kuluma komanso kutsutsana ndi chimbudzi cha chigombe, kuti valavu ikhalebebe kukhulupirika kwa chigombe cha nthawi yayitali.
2. Kapangidwe ka masika
Ntchito yomanga masika (DN150 ndi pamwambapa) imalola kuti chimbudzi chachikulu chizigwiritsidwa ntchito pa disc iliyonse ndipo disc imatseka payokha monga kusintha kwa mafakitale. Kuyesera kwawonetsa kuti izi zadzetsa kuchuluka kwa 25% mu moyo wa valavu komanso kuchepetsa ma 50% m'madzi.
Gawo lililonse la disc iwiri lili ndi akasupe ake omwe amapereka mphamvu yotseka yodziyimira pawokha ndipo amapezeka pang'ono ndi gawo laling'ono la 140 ° (mkuyu. 3) M'malo mwa 350 ° ya kasupe wachilendo wokhala ndi mabatani awiri.

Kapangidwe ka HIJAMEN kumachepetsa mikangano pofika 66%, yomwe imawongolera kwambiri kuti abwerere. Kuwala kwa chithandizo kumayikidwa kuchokera ku shinge yakunja kotero kuti Hinge yapamwamba itha kuthandizidwa ndi manja am'munsi panthawi yamagetsi. Izi zimathandiza kuti ma discs onse ayambe kuchita mwachangu komanso pafupi nthawi yomweyo, kupeza magwiridwe antchito abwino kwambiri.
Chachinayi, njira yolumikizirana ndi paipi
