Kodi valavu ya mpira yokwezedwa ndi trunnion ndi chiyani?
A Trunnion Yokwera valavu ya mpirandi valavu yamafakitale yogwira ntchito bwino kwambiri komwe mpirawo uli bwinoTrunnion Yokwera mkati mwa thupi la valavu ndipo silisuntha pansi pa kupanikizika kwapakati. Mosiyana ndi ma valavu oyandama a mpira, mphamvu zamadzimadzi pa mpira zimasamutsidwira ku mabearing m'malo mwa mpando wa valavu, zomwe zimachepetsa kusintha kwa mpando ndikuonetsetsa kuti mpando ukukhala wokhazikika. Kapangidwe kameneka kamaperekamphamvu yochepa, moyo wautali wautumiki, ndi magwiridwe antchito abwino kwambiri m'makina amphamvu komanso akuluakulu.
Makhalidwe a Trunnion Mounted Ball Valves
- Kapangidwe ka Mpando wa Ma Vavu Awiri: Imalola kutseka mbali zonse ziwiri popanda zoletsa kuyenda kwa madzi.
- Njira Yokonzera Zinthu Patsogolo ya Masika: Zimaonetsetsa kuti zitsekedwe pamwamba pa madzi kudzera m'mipando ya ma valve achitsulo chosapanga dzimbiri yolumikizidwa ndi PTFE.
- Thandizo la Kunyamula Pamwamba/Pansi: Amakonza mpira pamalo pake, kuchepetsa ntchito ya mpando wa valavu.
- Kapangidwe Kolimba: Thupi lokhuthala la valavu yokhala ndi matsinde apamwamba/apansi omwe akuwoneka komanso ma payipi owonjezera mafuta kuti azikonzedwa.
Momwe Ma Valves a Mpira Okwera Trunnion Amagwirira Ntchito
Mpirawo umazungulira 90° kuti utsegule kapena kutseka valavu. Ukatseka, pamwamba pake pozungulira pamatseka kuyenda kwa madzi; ukatsegula, njira yolunjika imalola kuti madzi adutse. Kapangidwe ka mpira wokwezedwa ndi Trunnion kamatsimikizira kuti:
- Kusindikiza Kokhazikika: Mipando ya ma valavu yodzaza kale imasunga kulumikizana kolimba mosasamala kanthu za kusinthasintha kwa kuthamanga kwa mpweya.
- Kuchepetsa Kuvala: Mabearing amayamwa kuthamanga kwa madzi, zomwe zimaletsa kusuntha kwa mpira.
Kugwiritsa ntchito ma Valves a Mpira Okwera a Trunnion
Ma valve a mpira opangidwa ndi Trunnion amagwira ntchito bwino kwambiri m'malo omwe ali ndi mphamvu zambiri komanso owononga, kuphatikizapo:
- Mapaipi oyeretsera mafuta ndi oyenda mtunda wautali
- Kukonza mankhwala ndi kupanga mphamvu
- Kusamalira madzi, HVAC, ndi machitidwe oteteza chilengedwe
- Kugawa kwa nthunzi ndi mpweya kutentha kwambiri
Trunnion Yokwera Valavu ya Mpira vs. Valavu ya Mpira Yoyandama: Kusiyana Kwakukulu
Valavu ya Mpira wa Trunnion vs Floating: Ndi iti yomwe ili yoyenera kugwiritsa ntchito kwanu?
| Mbali | Vavu Yoyandama ya Mpira | Valavu ya Mpira wa Trunnion Wokwera |
| Kapangidwe | Mpira umayandama; kulumikizana kwa tsinde limodzi lotsika | Trunnion ya Mpira Yokwezedwa kudzera m'mitengo yapamwamba/yotsika; mipando yosunthika |
| Njira Yotsekera | Kupanikizika kwapakati kumakankhira mpira motsutsana ndi mpando wotulukira | Kudzaza koyambirira kwa masika ndi mphamvu ya tsinde zimaonetsetsa kuti zitsekedwe |
| Kusamalira Kupanikizika | Yoyenera kuthamanga pang'ono/kwapakati | Yabwino kwambiri pamakina amphamvu kwambiri (mpaka 42.0Mpa) |
| Kulimba | Mipando imatha kusweka mosavuta ikapanikizika kwambiri | Yokhalitsa komanso yocheperako |
| Mtengo ndi Kukonza | Mtengo wotsika, kukonza kosavuta | Mtengo wokwera woyambira, wokonzedwa bwino kuti ugwirizane ndi zovuta |
NSW: Wogulitsa Valve Wodalirika wa Trunnion Mounted Ball Valve ku China
Wopanga Ma Vavu a NSWndi kampani yotsogola yopanga ma valve a mpira otsimikiziridwa ndi API 6D, kuphatikizapoma valve a mpira okwera pa trunnion, mavavu a mpira oyandamandifakitale ya mkuwa ya API 6D ya mpira wa valveZogulitsa zathu zimagwiritsidwa ntchito kwambiri mu mafuta, gasi wachilengedwe, ndi mapaipi amafakitale.
Mafotokozedwe Ofunika:
- Kukula: ½” mpaka 48″ (DN50–DN1200)
- Kuyeza kwa KupanikizikaKalasi 150LB–2500LB (1.6Mpa–42.0Mpa)
- Zipangizo: Chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo cha duplex, mkuwa wa aluminiyamu
- Miyezo: API, ANSI, GB, DIN
- Kuchuluka kwa Kutentha: -196°C mpaka +550°C
- Kuchitapo kanthu: Yogwiritsidwa ntchito ndi manja, yoyendetsedwa ndi mpweya, yamagetsi, kapena yoyendetsedwa ndi zida
Mapulogalamu: Kuyeretsa mafuta, kukonza mankhwala, kupereka madzi, kupanga magetsi, ndi zina zambiri.
