Zotsatirazi ndi chidule cha kuchuluka kwa ma valve agulugufe omwe ali ndi njira zosiyanasiyana zolumikizirana ndi mitundu yokhazikika, kutengera miyezo yodziwika bwino yamakampani ndi machitidwe ogwiritsira ntchito. Popeza makulidwe ake amatha kusiyanasiyana kutengera wopanga ndi mawonekedwe (monga kuchuluka kwa kuthamanga, mtundu wapakatikati, ndi zina zambiri), nkhaniyi imapereka chidziwitso cha mavavu a zfa.
Zotsatirazi ndizomwe zimatchulidwa m'mimba mwake (DN, mm).
1. M'mimba mwake mavavu agulugufe osankhidwa ndi njira yolumikizira
1. Valve yagulugufe wawafer
- M'mimba mwake: DN15-Chithunzi cha DN600
- Kufotokozera: Mavavu agulugufe wawafer ndi ophatikizika ndipo nthawi zambiri amagwiritsidwa ntchito pamakina apakati komanso otsika. Amakhala ndi mainchesi ambiri ndipo ndi oyenera mapaipi ang'onoang'ono ndi apakatikati. Ngati ipitilira DN600, mutha kusankha valavu imodzi yagulugufe ya flange (DN700-DN1000). Ma diameter akuluakulu (monga pamwamba pa DN1200) ndi osowa chifukwa cha kuyika kwakukulu ndi kusindikiza zofunika.
2. Valve yagulugufe wapawiri
- M'mimba mwake: DN50-DN3000
- Kufotokozera: Vavu yagulugufe yamtundu wa Double flange ndi yoyenera pazochitika zomwe zimafuna kukhazikika kwadongosolo komanso kusindikiza. Ili ndi mainchesi okulirapo ndipo imagwiritsidwa ntchito nthawi zambiri pamapaipi akulu monga kuthira madzi, malo opangira magetsi, ndi zina zambiri.
3. Single flange butterfly valve
- M'mimba mwake: DN700-DN1000
- Kufotokozera: Ma valve a flange amodzi amadya zinthu zochepa kuposa ma flange awiri kapena ma valve, zomwe zimachepetsa ndalama zopangira komanso zimachepetsanso ndalama zoyendera. Imangiriridwa ku flange ya chitoliro ndikumangirira m'malo mwake.
4. Valavu ya butterfly
- M'mimba mwake: DN50-Chithunzi cha DN600
- Kufotokozera: Mavavu agulugufe a Lug (mtundu wa Lug) ndi oyenera kumakina omwe ali kumapeto kwa mapaipi kapena omwe amafunikira kusokoneza pafupipafupi. Kutalika kwake ndi kochepa komanso kwapakati. Chifukwa cha zoperewera zamapangidwe, ntchito zazikulu zokhala ndi mainchesi ndizochepa.
5. Vavu yagulugufe ya mtundu wa U
- Mtundu wamtundu: DN100-DN1800
- Kufotokozera: Mavavu agulugufe amtundu wa U amagwiritsidwa ntchito kwambiri pamapaipi akulu-m'mimba mwake, monga madzi am'matauni, kuyeretsa zimbudzi, ndi zina zambiri, ndipo mawonekedwe ake ndi oyenera kuyenda kwakukulu komanso kutsika kwapakati kusiyana.
| Kufotokozera | Common Size Range (DN) | Mfundo zazikuluzikulu |
|---|---|---|
| Water Butterfly Valve | Chithunzi cha DN15-DN600 | Mapangidwe ang'onoang'ono, otsika mtengo, omwe amagwiritsidwa ntchito kwambiri pamakina otsika mpaka apakatikati; zazikuluzikulu za mautumiki osafunikira. |
| Lug Butterfly Valve | Chithunzi cha DN50-DN600 | Oyenera ntchito zakufa komanso machitidwe omwe amafunikira disassembly kuchokera mbali imodzi. Kuwongolera kwabwinoko pang'ono kuposa mtundu wamadzi. |
| Vavu ya Gulugufe Yemwe-Flanged | Chithunzi cha DN700-DN1000 | Wamba mu machitidwe okwiriridwa kapena otsika kwambiri; kulemera kopepuka komanso kosavuta kukhazikitsa. |
| Valovu ya Gulugufe Wapawiri | DN50-DN3000 (mpaka DN4000 nthawi zina) | Oyenera kupanikizika kwambiri, m'mimba mwake, ndi ntchito zovuta; ntchito yabwino yosindikizira. |
| Mtundu wa Gulugufe wa U-Type | Chithunzi cha DN50-DN1800 | Nthawi zambiri amakhala ndi mphira kapena wokhala ndi mizere yokwanira kuti isachite dzimbiri muzamankhwala. |

2. Mitundu yosiyanasiyana ya ma valve agulugufe osankhidwa malinga ndi mawonekedwe ake
1. Vavu yagulugufe yapakati
- Mtundu wamtundu: DN50-DN1200
- Kufotokozera: Chisindikizo cha butterfly chapakati (chisindikizo chofewa kapena chosindikizira zotanuka) chili ndi dongosolo losavuta, loyenera kutsika pang'onopang'ono komanso kutentha kwabwino, kutentha kwapakati, ndipo amagwiritsidwa ntchito kwambiri m'madzi, gasi ndi machitidwe ena.
2. Valovu yagulugufe yawiri
- Mtundu wamtundu: DN50-DN1800
- Kufotokozera: Valavu ya butterfly eccentric imachepetsa kuvala kwa chisindikizo kudzera mu mapangidwe a eccentric, ndi oyenera machitidwe ochepetsetsa komanso apakatikati, ali ndi mitundu yambiri, ndipo amagwiritsidwa ntchito kwambiri m'mafuta ndi gasi, mankhwala ndi mafakitale ena.
3. Vavu yagulugufe ya katatu
- Mtundu wamtundu: DN100-DN3000
- Kufotokozera: Valve yagulugufe ya katatu (chisindikizo cholimba) ndi yoyenera kutentha kwambiri, kuthamanga kwambiri komanso zovuta zogwirira ntchito. Ili ndi mitundu yayikulu kwambiri ndipo imagwiritsidwa ntchito nthawi zambiri pamapaipi akuluakulu amakampani, monga mphamvu, petrochemical, etc.
| Kufotokozera | Common Size Range | Mfundo zazikuluzikulu |
|---|---|---|
| Vavu ya Gulugufe Wapakati | DN40-DN1200 (mpaka DN2000 nthawi zina) | Ma tsinde ndi ma disc centerlines amalumikizana mofewa okhala oyenera kupanikizika kochepa, ntchito zambiri. |
| Valve ya Gulugufe Wachiwiri | DN100-DN2000 (mpaka DN3000) | Diski imachoka mwachangu pampando wotseguka kuti muchepetse kutha, komwe kumagwiritsidwa ntchito pakapanikizika. |
| Valve ya Gulugufe Watatu | DN100-DN3000 (mpaka DN4000) | Zopangidwira ma hightemp, high-pressure, zero-leakage applications, nthawi zambiri zimakhala zitsulo. |
