Metala i metala Noho Pahu Lepehe
✧ Hōʻike
ʻO ka valve butterfly eccentric e noho metala kahi ʻano o ka valve butterfly hana kiʻekiʻe i hoʻolālā ʻia no nā noi e koi ana i ka pani paʻa, ke kaomi kiʻekiʻe, a me ka hiki ke wela. Hōʻike ia i kahi noho i hana ʻia me ke kila, e like me ke kila kila a i ʻole nā mea hoʻohui ʻē aʻe, e pale aku i nā kūlana hana koi a me nā media abrasive. ʻO ka hoʻolālā triple eccentric e pili ana i ka offset o ka shaft, disc, a me ka noho, e hoʻonui ai i ka hana sealing a hoʻemi i ka lole. pono ka mana kahe pono a me ke kū'ē i nā kūlana paʻakikī. Ua kūpono lākou no ka lawelawe ʻana i kahi ākea ākea, me nā kinoea, nā wai, a me nā slurries. Ke koho ʻana i kahi metala e noho ana i triple eccentric butterfly valve, nā mea nui e noʻonoʻo ai i nā kūlana hana kūikawā, e like me ke kaomi, ka mahana, nā ʻano kahe, a me ke ʻano o ke hoomaluia nei ka media. Hoʻohui ʻia, pono e noʻonoʻo ʻia nā mea e like me ka hoʻohālikelike waiwai, nā pilina hope, nā kūlana ʻoihana, a me nā koi kūlohelohe.
✧ Nā hiʻohiʻona o ka metala a me ka metala e noho ana i ka ʻūpepa Butterfly
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 pili paha, no laila ʻo ka "frictionless" maoli ma waena o ka paʻa hoʻopaʻa ʻana. ke ola lawelawe o ka valve.
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.
ʻO ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve he pōkole, a he hana ʻokiʻoki hilinaʻi loa ia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono. o ke kahe ana. No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻoki a i ʻole ka hoʻoponopono a me ka throttling.
