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.

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
