Monga wopanga ma valve apamwamba kwambiri, ZFA nthawi zambiri imalandira mafunso okhudza kusiyana kwa mitundu yosiyanasiyana ya ma valve. Funso lodziwika bwino ndilakuti: Kodi pali kusiyana kotani pakati pa avalavu ya butterflyndi avalavu ya butterfly? Ngakhale amagawana mayina ofanana ndipo onse amagwiritsa ntchito mapangidwe amtundu wa diski, ntchito zawo, magwiridwe antchito, ndi magwiridwe antchito ndizosiyana kwambiri.
Bukuli likuwunika kusiyana kwakukuluku, kutengera luso la ZFA. Tidzafotokoza zoyambira —monga matanthauzo, kapangidwe kake, ndi mfundo zoyendetsera ntchito. Kaya ndinu mainjiniya, katswiri wogula zinthu, kapena katswiri wamakampani, nkhaniyi ikuthandizani kupanga chisankho mwanzeru.
1. Kodi Vavu ya Gulugufe ndi Chiyani?
Vavu yagulugufe ndi valavu yozungulira ya quarter-turn yomwe imagwiritsidwa ntchito makamaka pakuwongolera mayendedwe kapena kudzipatula pamapaipi. Imakhala ndi chimbale chomwe chimazungulira chapakati kuti chitsegule kapena kutseka njira yolowera.
1.1 Momwe Gulugufe Amagwirira Ntchito
Valavu imagwira ntchito pozungulira ma disk 90 madigiri: kutseguka kwathunthu, kulola kuyenda kosasunthika, kapena kutsekedwa, kutsekereza njira yodutsa. Kuzungulira pang'ono kumapangitsa kugwedezeka, kumapangitsa kuti ikhale yoyenera kuyendetsa kayendedwe kake.
1.2 Kugwiritsa Ntchito Wamba
- Malo Ochizira Madzi
- HVAC Systems
- Chemical Processing
- Makampani a Chakudya ndi Chakumwa
2. Kodi Vavu Yoyang'ana Gulugufe ndi Chiyani?
Valovu yoyang'ana gulugufe, yomwe imadziwikanso kuti double-disc check valve, ndi valavu yosabwerera kapena njira imodzi yomwe imalepheretsa kubwereranso m'mapaipi. Mosiyana ndi mavavu agulugufe, imagwira ntchito yokha popanda kutulutsa kwakunja.
2.1 Mfundo Yogwirira Ntchito
Kupita patsogolo kumakankhira chimbale chotseguka, kugonjetsa kukangana kwa masika. Kuthamanga kukayima kapena kutembenuka, kasupe amatseka mwamsanga diski, kupanga chisindikizo cholimba kuti chiteteze kubwerera. Kuchita izi kodziwikiratu sikufuna kulowererapo kwa munthu.
2.2 Kugwiritsa Ntchito Wamba
- Mizere Yotulutsa Pampu
- Compressor Systems
- Mapulatifomu a Marine ndi Offshore
- Kuwongolera kwamadzi onyansa
3. Kusiyana Kwakukulu Pakati pa Mavavu a Gulugufe ndi Mavavu a Gulugufe
Ngakhale onsewa amagwiritsa ntchito makina a disc, ntchito zawo zazikulu ndizosiyana. Nayi kufananitsa mbali ndi mbali:
| Mbali | Valve ya Butterfly | Gulugufe Onani Vavu |
| Ntchito Yoyambira | Kuwongolera kuyenda komanso kudzipatula | Kupewa kubwerera mmbuyo |
| Ntchito | Kuzungulira kwapamanja kapena koyendetsedwa | Zadzidzidzi (zodzaza masika) |
| Chimbale Design | Single disc pa shaft | Zipinda ziwiri zokhala ndi mahinji ndi akasupe |
| Njira Yoyenda | Bidirectional (ndi kusindikiza koyenera) | Unidirectional kokha |
| Kuyika | Chophika, chophika kapena chophika | Chophika, chophika kapena chophika |
Gome ili likuwonetsa zifukwa zosankhira chimodzi pa chimzake: mavavu agulugufe owongolera, fufuzani mavavu kuti atetezedwe.
6. Nyundo ya Madzi ndi Kuthamanga Kwambiri
Nyundo yamadzi imachitika pamene kutuluka kwa madzi kumayimitsidwa mwadzidzidzi, monga pamene valavu imatsekedwa mofulumira kapena mpope watsekedwa mwadzidzidzi. Izi zimapangitsa mphamvu ya kinetic kusandulika kukhala mphamvu yothamanga yomwe imafalikira m'mphepete mwa chitoliro. Kugwedeza uku kungayambitse kuphulika kwa chitoliro, kumasuka kwa flange, kapena kuwonongeka kwa valve. Ma valve a butterfly ndi ma valve a gulugufe amasiyana mu luso lawo logwira nyundo yamadzi chifukwa cha mapangidwe awo ndi njira zogwirira ntchito.
6.1 Mavavu a Gulugufe ndi Nyundo Yamadzi
Liwiro limene valavu ya gulugufe imatseka imadalira njira yake yogwiritsira ntchito (pamanja, pneumatic, kapena magetsi). Kutseka kofulumira kungayambitse nyundo yamadzi, makamaka mu machitidwe omwe ali ndi maulendo othamanga kwambiri kapena kuthamanga kwambiri. Izi zimafuna chidwi chapadera pamakina opopera.
Mavavu agulugufe sanapangidwe kuti ateteze kubwerera mmbuyo. Ngati pali chiopsezo chobwerera m'mbuyo mu dongosolo, nyundo yamadzi imatha kuwonjezereka ndi kubwereranso.
6.2 Mavavu Agulugufe Ndi Nyundo Yamadzi
Ma valve owunika agulugufe (ma valve oyang'ana pawiri-disc) amatseka okha pogwiritsa ntchito ma disc odzaza ndi masika kuti apewe kubwerera. Amapangidwa kuti ayankhe mofulumira kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Komabe, kutsekedwa kofulumira kumeneku kungayambitse nyundo yamadzi.
7. Mafunso Ofunsidwa Kawirikawiri
Kodi ndingasiyanitse bwanji valavu ya butterfly ndi cheki?
Mavavu agulugufe ali ndi makina oyendetsa, pomwe ma valavu owunika alibe.
Kodi valavu ya gulugufe ingagwiritsidwe ntchito ngati valavu?
Ayi, chifukwa ilibe njira yotseka yokha. Chotsaliracho chilinso chowona.
Kodi mavavuwa amafunikira chisamaliro chotani?
Mavavu a butterflyamafuna kuyang'anitsitsa mipando nthawi zonse;fufuzani ma valvezimafunika kuyendera kasupe miyezi 6-12 iliyonse.
