ʻEkolu Offset Butterfly Valve
✧ Hōʻike
ʻO ka valve butterfly offset triple he ʻano o ka pahu pahu hāhā i hoʻolālā ʻia e hāʻawi i ka mana kahe kūpono a hilinaʻi hoʻi i nā noi ʻoihana like ʻole. ʻAʻole e like me nā valves butterfly maʻamau, i loaʻa i ka concentric a eccentric hoʻolālā, kahi triple offset butterfly valve e hōʻike ana i kahi hoʻolālā kūʻokoʻa me ʻekolu offsets: Shaft Offset: ʻO ke kikowaena o ke kumu i hoʻonohonoho ʻia ma hope o ke kikowaena o ka ili hoʻopaʻa, e kōkua i ka hōʻemi ʻana i ka ʻaʻahu a me ka friction i ka wā o ka hana, ka hopena i ka hoʻomaikaʻi ʻana i ka hana a me ke ola lawelawe lōʻihi. e hiki ai i ka pahupaʻi paʻa paʻa me ka paʻa paʻa paʻa, e ho'ēmi i ka hiki no ka leakage a me ka hoʻomaikaʻi 'ana i ka valve. ke kū'ē i kaʻaʻahu a me ka abrasion, kūpono ia no nā noi koi i nāʻoihana e like me kaʻaila a me ke kinoea, ka petrochemical, ka hana kemika, ka hana mana, a me nā mea hou aku. Pono e noʻonoʻo pono ʻia nā helu wela, nā pilina hope, a me nā kūlana ʻoihana e hōʻoia i ka hana kūpono a me ka hana maikaʻi loa no ka noi kikoʻī.
✧ Nā hiʻohiʻona o Triple Offset Butterfly Valve Wafer Connection
Hana ʻia ka valve butterfly ʻekolu-eccentric me kahi ʻano ʻekolu-eccentric o ka valve butterfly, ʻo ia hoʻi, ua hoʻohui ʻia kahi angular eccentricity ma ke kumu o ka metala maʻamau i hoʻopaʻa ʻia ʻelua-eccentric butterfly valve. ʻO ka hana nui o kēia Angle eccentricity ka hana ʻana i ka valve i ke kaʻina o ka wehe ʻana a i ʻole ka pani ʻana i ka hana, ʻo kēlā me kēia wahi ma waena o ke apo sealing a me ka noho e hoʻokaʻawale koke ʻia a hoʻopili ʻia paha, no laila ʻo ka "frictionless" maoli ma waena o ka hui hoʻopaʻa ʻana, e hoʻolōʻihi i ke ola lawelawe o ka pahu.
ʻEkolu ka wehewehe ʻana i ke kiʻi hoʻolālā eccentric
Eccentric 1: Aia ka pahu valve ma hope o ke kumu noho i hiki ke paʻa loa ka sila a puni ka noho holoʻokoʻa.
Eccentric 2: Hoʻokaʻawale ka laina waena o ka valve shaft mai ka paipu a me ka laina waena valve, i pale ʻia mai ka hoʻopilikia ʻana i ka wehe a me ka pani ʻana o ka valve.
Eccentric 3: Hoʻokaʻawale ka pahu cone noho mai ka laina waena o ka pahu valve, kahi e hoʻopau ai i ka friction i ka wā e pani ai a wehe ʻia a hāʻawi i kahi sila hoʻopaʻa like a puni ka noho holoʻokoʻa.
✧ ʻEkolu mau mea maikaʻi o ka valve butterfly eccentric
1. Aia ka pahu valve ma hope o ka pahu valve plate, e hiki ai i ka sila ke ho'opa'a a ho'opā i ka noho holo'oko'a.
2. ua hoʻokaʻawale ka laina o ka valve shaft mai ka paipu a me ka laina valve, i pale ʻia mai ke keakea ʻana o ka wehe ʻana a me ka pani ʻana.
3. Hoʻokaʻawale ka axis cone noho mai ka laina valve e hoʻopau i ka friction i ka wā o ka pani ʻana a me ka wehe ʻana a no ka hoʻokō ʻana i kahi sila hoʻopaʻa like a puni ka noho holoʻokoʻa.
✧ Pono o Triple Offset Butterfly Valve Wafer Connection
I ka wā o ka wehe ʻana a me ka pani ʻana o ka pahu kila kila, no ka mea, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, ʻaʻole hiki ke ʻaʻahu.
He pōkole ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve, a he mea hilinaʻi loa ia i ka hana ʻoki ʻia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, ua kūpono loa ia no ka hoʻoponopono ʻana i ke kahe kahe. No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻana a i ʻole ka hoʻoponopono a me ka throttling.

✧ Mahope o ke kuai ana
Ma ke ʻano he mea hana a me ka mea kūʻai aku, ke hoʻohiki nei mākou e hāʻawi i nā mea kūʻai aku me ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, me kēia mau mea:
1. Hāʻawi i nā alakaʻi hoʻohana huahana a me nā manaʻo mālama.
2.No nā hemahema i hana ʻia e nā pilikia maikaʻi o ka huahana, hoʻohiki mākou e hāʻawi i ke kākoʻo ʻenehana a me ka hoʻoponopono pilikia i loko o ka manawa pōkole loa.
3.Except no ka pōʻino i hanaʻia e ka hoʻohana maʻamau, hāʻawi mākou i ka hoʻoponopono manuahi a me nā lawelawe pani.
4. Ke hoʻohiki nei mākou e pane wikiwiki i nā pono lawelawe o ka mea kūʻai aku i ka wā o ka hōʻoia huahana.
5. Hāʻawi mākou i ke kākoʻo ʻenehana no ka wā lōʻihi, nā lawelawe kūkākūkā pūnaewele a me nā lawelawe hoʻomaʻamaʻa. ʻO kā mākou pahuhopu ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike lawelawe maikaʻi loa a hoʻolilo i ka ʻike o nā mea kūʻai aku i mea ʻoluʻolu a maʻalahi.
