Pālua Eccentric Pulelehua Valve
He aha ka Double Eccentric Butterfly Valve?
Pālua Eccentric Pulelehua Valve he huahana hoʻolālā offset pālua hou me ka ʻenehana alakaʻi honua holomua. Loaʻa i kēia valve butterfly kahi ʻano kū hoʻokahi me ka hana sila hilinaʻi loa, nā kūlana hana ākea a me ka torque hana haʻahaʻa.
ʻO nā hiʻohiʻona nui o nā kiwikā pule pālua eccentric ʻo ia ka pālua eccentric, i kapa ʻia hoʻi he hoʻolālā disc offset pālua.
ʻAe ia i ka disc e neʻe aku mai ka noho e hōʻemi ana i ka torque holo a me ka noho ʻaʻahu, he pono nui ia i ka hoʻohālikelike ʻia me nā valves butterfly concentric.
Hoʻokuʻu ʻia ke kaomi ma ka diski ma hope o kekahi mau kekelē o ka wehe ʻana e hōʻemi ana i ka ʻaʻahu ʻana o ke sila diski. Eia kekahi, hoʻemi ka hoʻolālā i ke kaomi ʻana o ke sila ʻana e hōʻoiaʻiʻo ana i nā torque hana haʻahaʻa.
Hiki ke hoʻololi ʻia ke sila o ke koʻokoʻo ma lalo o ke kaomi e hiki ai ke mālama maʻalahi. Hoʻopaʻa nā sila o ka EPDM i ka paʻa 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 ʻo nā wēlau o ke koʻokoʻo i pale ʻia e hoʻopaʻa i ka lōʻihi no ka mea ʻaʻohe ʻili hao ductile i uhi ʻole ʻia i hōʻike ʻia i ka pāpāho.

- ʻO ka hoʻolālā noho PTFE i hoʻopaʻa ʻia me ka dynamic-mount kū hoʻokahi he maʻalahi a hilinaʻi loa
- Hiki i ka hoʻonohonoho sila lehelehe ke uku no nā loli i ka mahana a me ke kaomi, e mālama i ka sila
- ʻO ke ola lawelawe lōʻihi, hiki ke ola keʻena hoʻokolohua a hiki i 670,000 mau manawa
- Hana sila hilinaʻi loa: bi-directional zero leakage
- He mea maʻalahi ke hoʻololi i ka noho ma ka wehe ʻana i ka mea hoʻokomo, kūpono no ka mālama.
- Aia kahi ʻōnaehana pahū palekana ma ka piko o ke kumu
- Nā hiʻohiʻona hoʻoponopono maikaʻi loa

ʻAno kumu-uka
Ke kahe ka pāpāho mai ke kua o ka valve butterfly a i ke alo, ua sila ponoʻī ʻia ka papa butterfly ma muli o ka hoʻokuʻi ʻana o ka pāpāho i luna a me ke kaomi o ka noho.
ʻAno kumu-iho
Ke kahe ka pāpāho mai ke alo o ka valve butterfly a i ke kua, hoʻopuka ka medium i ka pahū ma ke kihi o ke kua o ka noho a hana ka papa butterfly i kahi sila ponoʻī kaomi.

He aha ka mea i hoʻohana ʻia ai ka Double Eccentric Butterfly Valve?
Hana kiʻekiʻekiwikā pulelehua eccentric pāluanā noi
1: Nā kūlana hana alapine kiʻekiʻe wikiwiki: i loko o ka ʻōnaehana hoʻokaʻawale ea, hiki ke hana ʻia no ka manawa lōʻihi i loko o 1 kekona hoʻololi,
Hiki i ke ola ke piʻi i 1 miliona mau manawa
2: Nā kūlana hana wela kiʻekiʻe: He kūpono ka noho o ka mea PPL no nā mahana kiʻekiʻe o 250 degere C.
3: Nā kūlana sila ʻelua ʻaoʻao kiʻekiʻe 6-paepae: i ka ʻōnaehana hoʻopau condensate he ākea nā noi.
4: Nā kūlana hana oxygen: Hiki ke hoʻohana ʻia kēia valve ma hope o ka mālama ʻana i ka degreasing no nā kūlana hana oxygen, ma nā ʻāpana
Ma ke ʻano o ka hoʻomākaukau ʻana, ka hōʻuluʻulu ʻana, ka hoʻāʻo ʻana a me ka hoʻopili ʻana, ua hoʻomaʻemaʻe ʻia ka valve e like me nā kaʻina hana.
5: Nā kūlana vacuum: ka hana kiʻekiʻe maʻamau (ʻelua eccentric) butterfly valve i helu ʻia no ka hoʻokō ʻana i ka vacuum
2x10-2. Loaʻa pū nā kiwikā vacuum kiʻekiʻe kūikawā me ka vacuum o 2x10-5.
