Mavavu agulugufe ndi gulu la mavavu oyenda mozungulira kotala omwe amagwiritsidwa ntchito pamapaipi, pali mitundu yambiri ya ma valve agulugufe.Nthawi zambiri, mitundu yosiyanasiyana ya ma valve agulugufe amagawidwa ndi kulumikizana, zida,mawonekedwe, kupanga mapangidwe, ndi zina zotero.ZFA ndi amodzi mwa opanga ma valve agulugufe otchuka, opanga ma valve agulugufe wa flange, ndi opanga ma valve agulugufe ku China.
Mitundu ya ma valve a butterfly ndi Connection, ndi mitundu inayi.
4.Valve ya butterfly ya U-gawo
5. Weld valavu butterfly
Mitundu ya valavu ya gulugufe ndi zida za thupi la valavu ili pansi pa mitundu isanu.
1. Vavu yagulugufe yachitsulo yachitsulo
2. valavu ya butterfly ya carbon steel
3. Vavu yagulugufe yachitsulo chosapanga dzimbiri
4. Mgonero wosapanga dzimbiri valavu gulugufe
5. Valve ya butterfly ya mkuwa
Mitundu ya ma valve a butterfly popanga matupi a valve ili pansi pa mitundu itatu
1. Vavu ya gulugufe
2. Kuwotcherera agulugufe valavu
3. Kupanga valavu yagulugufe
Kuponya

Mitundu ndi mawonekedwe, ili pansipa mitundu iwiri.
1.Centerline Butterfly Valve
a.Ubwino: Mapangidwe osavuta komanso osavuta kupanga, azachuma;
b.Zoipa: Mbalame ya butterfly ndi mpando wa valve nthawi zonse zimakhala mu chikhalidwe cha extrusion ndi scraping, mtunda wotsutsa ndi waukulu ndipo kuvala kumathamanga.
c.Ntchito: Amagwiritsidwa ntchito kwambiri m'magawo ambiri monga mafuta, mankhwala, zitsulo, ndi mphamvu yamadzi.
2.Eccentric Butterfly Valve
a.Ubwino: Imani kutentha kwambiri ndi kupanikizika, Wonjezerani moyo wa mpando wa valve
b.Zoipa: Zokwera mtengo komanso zovuta kupanga
c.Mapulogalamu: Amagwiritsidwa ntchito kwambiri pamapaipi amadzimadzi amadzi ndi ngalande, zimbudzi, zomangamanga, mafuta, mankhwala, nsalu zopepuka, kupanga mapepala, mphamvu yamadzi, zitsulo, mphamvu, ndi ntchito zina.
Tiyeni tiwunikenso mfundo zoyenera komanso mbiri yakale ya Centerline butterfly valve ndi eccentric butterfly valve mwatsatanetsatane.
The centerline Butterfly Valve imadziwika ndi pakati pa tsinde, pakati pa gulugufe mbale, ndi pakati pa thupi pa malo omwewo, monga valavu yapakati.Valavu yagulugufe yokhazikika, nthawi zambiri imachokera ku kukula kwa DN50 mpaka DN2200, Kusindikiza kwapakati pa gulugufe valavu ndi yofewa, choncho ndi yotsika kutentha komanso yotsika kwambiri.Vavu ya butterfly ya ductile iron ndi imodzi mwamavavu agulugufe omwe amakhazikika
Kupanikizika: DN1200, Max kuthamanga PN6;
Kutentha: Malinga ndi kusindikiza zipangizo, Mwachitsanzo, NBR, Max kutentha: 100 ℃, EPDM, Max kutentha: 150 ℃;FRM, Max kutentha: 200 ℃;SBR, Max kutentha: 100 ℃;CR, Max kutentha: 100 ℃;NR, Max kutentha: 70 ℃;HR, Max kutentha: 100 ℃;UR, Max kutentha:40 ℃.
Kwa eccentric butterfly valves, ndi mitundu itatu
a.Single Eccentric Butterfly Valve
b.Valovu yagulugufe wapawiri
Mbiri ya mtundu wagulugufe wamtundu wa eccentric
The single eccentric butterfly valve ndi mtundu wa gulugufe valavu opangidwa kuthetsa vuto kufinya gulugufe mbale ndi mpando valavu pakati mzere gulugufe valavu.The tsinde olamulira apatuka pakati pa valavu gulugufe kotero kuti m'munsi mapeto a gulugufe valavu sakhalanso olamulira kasinthasintha, amene amabalalitsa ndi kuchepetsa kusintha kufinya chapamwamba ndi m'munsi malekezero a gulugufe mbale ndi mpando valavu.
Vavu yagulugufe wapawiri ndi imodzi mwamitundu yamagulugufe, tsinde la agulugufe limachoka pakatikati pa mbale yagulugufe komanso pakati pa thupi.Zotsatira za eccentricity pawiri zimathandiza kuti gulugufe mbale mwamsanga achotse pampando pambuyo valavu kutsegulidwa, amene amathandiza kuthetsa kufinya kwambiri ndi kukanda pakati pa gulugufe mbale ndi mpando ndi bwino mpando moyo.Kuchepetsa kwakukulu kwa kukwapula kumapangitsa kuti zitheke kugwiritsa ntchito mipando yachitsulo pawiri eccentric agulugufe mavavu, amene angagwiritsidwe ntchito pa ntchito kutentha kwambiri.
The katatu eccentric gulugufe valavu ndi mtundu wa gulugufe valavu, chifukwa tsinde olamulira udindo kupatuka pa nthawi yomweyo, kupanga conical olamulira gulugufe mbale kusindikiza pamwamba kupatuka pa olamulira thupi cylindrical, kusindikiza pamwamba pa gulugufe mbale ndi elliptical, mawonekedwe a kusindikiza pamwamba kotero ndi asymmetric, mbali imodzi imatsatiridwa ndi thupi lapakati, mbali inayo ndi yofanana ndi thupi lapakati.Ma valve agulugufe atatu a eccentric amasintha malo osindikizira, osakhalanso kusindikiza, koma kusindikiza kwa torsion, kudalira malo okhudzana ndi mpando wa valve kuti akwaniritse kusindikiza, kuthetsa vuto la zero kutayikira kwa mpando wa valve wachitsulo.Popeza kukhudzana kwapamwamba ndi kuthamanga kwapakati kumakhala kofanana, kumathetsanso vuto la kuthamanga kwambiri ndi kutentha kwakukulu, ndipo valve ya butterfly imagwiritsidwa ntchito kwambiri.
