He aha ia ʻo Double Eccentric Butterfly Valve?
ʻO ka pāpaʻi kiʻi kiʻi lua he mea hoʻolālā hoʻolālā pālua offset hou me ka ʻenehana alakaʻi honua kiʻekiʻe.He ʻano kū hoʻokahi kēia ʻano kīpē butterfly me ka hana sealing hilinaʻi nui, nā kūlana hana ākea a me ka torque hana haʻahaʻa.
ʻO nā hiʻohiʻona koʻikoʻi o nā kīwaha papalua eccentric ʻo ka pālua eccentric, i kapa ʻia hoʻi ka hoʻolālā disc offset pālua.
hiki iā ia ke neʻe aku i ka diski mai ka noho e hoʻemi ana i ka torque holo a me ka ʻaʻahu o ka noho, ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana i nā valve concentric butterfly.
Hoʻokuʻu ʻia ka haʻalulu ma ka disc ma hope o kekahi mau degere o ka wehe ʻana e hōʻemi ana i ka ʻaʻahu ʻana o ke sila diski.Eia kekahi, ʻo ka hoʻolālā e hōʻemi i ka paʻi ʻana o ka hoʻopaʻa ʻana e hōʻoia ai i nā torque hana haʻahaʻa.
Hiki ke hoʻololi ʻia ka shaft sealing ma lalo o ke kaomi e hiki ai i ka mālama maʻalahi.Hoʻopaʻa paʻa ka paʻa ʻana o ka EPDM mai loko a i waho, a pale aku nā sila NBR i nā haumia a me nā wai mai waho.
ʻO nā bearings PTFE haʻahaʻa haʻahaʻa e hōʻoiaʻiʻo i nā torque hana haʻahaʻa a hoʻopau ka lāʻau pale i ka paʻa paʻa no ka mea ʻaʻohe ʻili hao ductile uncoated i ʻike ʻia i ka media.
ʻO nā hiʻohiʻona nui o nā kiwi lele eccentric pālua
ʻO ka machnism sila oʻO ka pāpaʻi kiʻi kiʻi lua
Nā hiʻohiʻona nui oʻO NORTECH nā kīwī lele lua
- ʻO ka hoʻolālā noho PTFE dynamic-mauna i hoʻopaʻa ʻia he maʻalahi a hilinaʻi loa
- Hiki i ka lehelehe seal structure ke hoʻololi i ka mahana a me ke kaomi, mālama i ka sila
- ʻO ke ola lawelawe lōʻihi, hiki i ke ola keʻena hana ke piʻi i 670,000 mau manawa
- Hana ʻia ʻo Ultra-Reliable seal: bi-directional zero leakage
- He mea maʻalahi ke pani i ka noho ma ka wehe ʻana i ka mea hoʻokomo, maʻalahi no ka mālama ʻana.
- Aia kahi ʻano hoʻoheheʻe palekana ma luna o ke kumu
- ʻO nā hiʻohiʻona hoʻoponopono maikaʻi
- Hoʻolālā pale ahi
ʻO ka machnism sila oʻO ka pāpaʻi kiʻi kiʻi lua
ʻAno kumu-upstream
Ke kahe ka media mai ke kua o ka valve butterfly a i ke alo, ua hoʻopaʻa ʻia ka papa pelelele ma muli o ke kī ʻana i luna o ka media a me ke kaomi o ka noho.
ʻAno kumu-lalo
Ke kahe ka media mai ke alo o ka valve butterfly a i ke kua, e hoʻoulu ka mea waena ma ke kihi o ke kua o ka noho a hoʻokumu ka papa butterfly i kahi hoʻopaʻa paʻa ponoʻī.
Ke ʻano o ka hana ʻana no ka pāpaʻi kiʻi pālua Eccentric Butterfly
Hoʻohana i ka lepa no nā kiwi lele lele DN40-DN200.
ʻO ka mea hoʻohana pahu pahu lima no ka piha piha ʻana o nā kiwi lele.
Pneumatic actuator no ka piha piha o na kiwi lele
Mea hana uila no ka piha piha o na kiwi lele
ʻO ke kumu manuahi me ka ʻole o ka actuator, i hana ʻia no nā mea kūʻai aku me kāu mea hana ponoʻī.
Nā kikoʻī kikoʻī o nā kiwi lele eccentric pālua

Hōʻike Huahana:
He aha ka mea i hoʻohana ʻia no ka Double Eccentric Butterfly Valve?
Kiʻekiʻe-hanalua pele eccentric valvenā noi
1: High-speed kiʻekiʻe-frequency kūlana hana: i loko o ka ea hoʻokaʻawale'ōnaehana, hiki ke hana no ka manawa lōʻihi i loko o 1 kekona hoololi,
Hiki ke ola i 1 miliona mau manawa
2: Nā kūlana hana wela kiʻekiʻe: Ua kūpono ka noho o ka mea PPL no nā wela kiʻekiʻe o 250 degere C.
3: High-press double-sided 6-stage sealing condition: i loko o ka condensate hoʻopau ʻōnaehana he laulā o nā noi.
4: Nā kūlana hana o ka oxygen: Hiki ke hoʻohana ʻia kēia valve ma hope o ka hoʻomaʻamaʻa degreasing no nā kūlana hana oxygen, ma nā ʻāpana
Ma ke ʻano o ka hoʻomākaukau, ka hui ʻana, ka hoʻāʻo ʻana a me ka hoʻopili ʻana, hoʻomaʻemaʻe ʻia ka valve e like me nā kaʻina hana.
5: Nā kūlana ʻawaʻawa: kūlana kiʻekiʻe-hana kiʻekiʻe (double eccentric) butterfly valve helu ʻia e hoʻokō ai i ka momi
2x10-2.Loaʻa pū ʻia nā kīwaha kiʻekiʻe kiʻekiʻe me kahi ʻōpala o 2x10-5.
