Ua kapa ʻia ka valve eccentric butterfly ʻelua ma muli o kāna mau hale eccentric ʻelua.No laila he aha ke ʻano o ke ʻano eccentric pālua?
ʻO ka mea i kapa ʻia ʻo double eccentric, ʻo ka eccentric mua e pili ana i ka pahu valve ma waho o ke kikowaena o ka ʻili hoʻopaʻa, ʻo ia hoʻi ke kumu ma hope o ke alo o ka pā valve.Hoʻolilo kēia eccentricity i ka ʻili pili o ka pā valve a me ka noho valve i mea hoʻopaʻa paʻa, ka mea e lanakila nui ai i nā hemahema i loko o nā valve concentric butterfly, pēlā e hoʻopau ai i ka hiki ke hoʻoheheʻe i loko ma ka ʻaoʻao o luna a me lalo ma waena o ka pahu valve a noho kiwi.
ʻO kekahi eccentricity e pili ana i ke kikowaena kino valve a me ka axis stem hema a me ka ʻākau offset, ʻo ia hoʻi, hoʻokaʻawale ke kumu i ka papa pepeke i ʻelua ʻāpana, hoʻokahi ʻoi aʻe a emi mai hoʻokahi.Hiki i kēia eccentricity ke hana i ka papa pele i ka wehe a me ka pani ʻana i ke kaʻina hiki ke wehe koke a kokoke paha i ka noho valve, e hoʻemi i ka friction ma waena o ka pā valve a me ka noho valve i hoʻopaʻa ʻia, e hoʻemi i ka lole a me ka waimaka, e hoʻemi i ka puka a me ka pani ʻana o ka torque, a hoʻonui i ke ola o ka noho valve.
Pehea e hoʻopaʻa ʻia ai nā ʻāpapa ʻāpau Eccentric Butterfly?
ʻO ka pōʻai o waho o ka pā valve a me ka noho i hoʻopaʻa ʻia o ka lua eccentric butterfly valve e mīkini ʻia i loko o ka hemispherical surface, a ʻo ka ʻaoʻao spherical o waho o ka pā valve e kaomi i ka ʻili spherical o loko o ka noho i hoʻopaʻa ʻia e hana i ka deformation elastic e hoʻokō i kahi pani pani. mokuʻāina.ʻO ka sila o ka lua eccentric butterfly valve no ke kūlana sealing structure,ʻo ia hoʻi ka sila o ka pā valve a me ka noho valve i ka laina laina, aʻo ke apo sealing e hana mauʻia i ka lāʻau a iʻole ka PTFE.No laila,ʻaʻole ia e kū'ē i ke kiʻekiʻe kiʻekiʻe, aʻo ka noi i ka'ōnaehana kiʻekiʻe e alakaʻi i ka leakage.
He aha ka ʻāpana nui o Double Eccentric Butterfly Valve?
Mai ke kiʻi ma luna, hiki iā mākou ke ʻike maopopo i nā ʻāpana nui o ka lua Eccentric Butterfly Valve i loaʻa nā mea ʻehiku ma hope:
Kino: ʻO ka hale nui o ka valve, i hana mau ʻia me ka hao hoʻoheheʻe, ka hao ductile, a i ʻole ke kila kila, i hoʻolālā ʻia e hoʻopaʻa i nā ʻāpana o loko o ka valve.
Disc: ʻO ka mea kikowaena o ka valve e hoʻololi i loko o ke kino valve e hoʻomalu i ke kahe o ka wai.Hana ʻia ka diski me ka hao, ke kila a i ʻole ke keleawe, a he ʻano palahalaha a i ʻole ke ʻano e like me ke ʻano o ke kino valve.
Shaft Bearings: Aia nā bearings i loko o ke kino valve a kākoʻo i ke kumu, e ʻae iā ia e hoʻololi mālie a hoʻemi i ka friction.
Sealing Ring: ua hoʻopaʻa ʻia ke apo sealing rubber i ka pā valve e ka pā kaomi a me nā wili kila kila, a ua hoʻoponopono ʻia ka ratio sealing valve ma ka hoʻoponopono ʻana i nā wili.
Sealing Seat: he ʻāpana ia o ka valve e hoʻopaʻa ai i ka disc a pale i ka leaka o ka wai ma o ka valve ke pani ʻia.
ʻO ke kumu hoʻokele: hoʻopili i ka mea hoʻokele i ka pā valve a hoʻouna i ka ikaika e hoʻoneʻe i ka flap valve i ke kūlana i makemake ʻia.
Actuator: hoʻomalu i ke kūlana o ka diski i loko o ke kino valve.A kau ʻia ma luna o ke kino valve.
Puna Kiʻi: Hawle
Hāʻawi ka wikiō aʻe i kahi hiʻohiʻona ʻike a me ka kikoʻī o ka hoʻolālā a me ka hiʻohiʻona o ka valve eccentric butterfly valve.
Nā Pōmaikaʻi a me nā pōʻino ʻole o ka pāpaʻi ʻo Double Eccentric Butterfly Valve
Pono:
1 Hoʻolālā kūpono, hoʻolālā paʻa, maʻalahi e hoʻokomo a wehe, hana maʻalahi, mālama i ka hana, maʻalahi, a me ka mālama maʻalahi.
2 ʻO ka hoʻolālā eccentric e hōʻemi i ka friction o ke apo sealing a hoʻonui i ke ola lawelawe o ka valve.
3 Hoʻopaʻa piha ʻia, ʻaʻohe leaka.Hiki ke hoʻohana ʻia ma ke kūlana vacuum kiʻekiʻe
4 E hoʻololi i ka mea o ka valve plate seal, butterfly plate, shaft, etc., hiki ke hoʻopili ʻia i nā ʻano media like ʻole a me nā mahana like ʻole.
5 Ka hoʻolālā ʻana, ikaika kiʻekiʻe, ʻāpana kahe nui, pale liʻiliʻi
Nā hemahema:
No ka mea ʻo ka hoʻopaʻa ʻana he kūlana hoʻopaʻa hoʻopaʻa ʻana, ʻo ka ʻili hoʻopaʻa ʻana o ka pā butterfly a me ka noho valve e pili ana i ka laina laina, a ua hana ʻia ka hoʻopaʻa ʻana e ka elastic deformation i hoʻokumu ʻia e ka papa butterfly e kaomi ana i ka noho valve, no laila ke koi nei i kahi pani kiʻekiʻe. kūlana a he haʻahaʻa haʻahaʻa no ke kaomi kiʻekiʻe a me ka wela kiʻekiʻe.
ʻO ka papa hoʻohana ʻana o ka pāpaʻi pālua Offset Butterfly:
- ʻO ka mālama wai a me nā ʻōnaehana hoʻolaha
- ʻoihana mining
- Nā hale hana moku a me nā ʻeli
- Mea kanu kemika a me ka petrochemical
- ʻO nā ʻoihana meaʻai a me nā kemika
- ʻO nā hana ʻaila a me ke kinoea
- Pūnaehana kinai ahi
- Pūnaehana HVAC
- ʻO nā wai a me nā kinoea ʻaʻole ikaika (ke kinoea kūlohelohe, CO-gas, nā huahana ʻaila, etc.)
