Nā hiʻohiʻona huahana
1, ʻelua hoʻolālā hoʻolālā eccentric, ʻo ke ola lawelawe he 5 mau manawa o ka valve butterfly maʻamau
2, Liʻiliʻi hoʻololi torque.
ʻO nā ʻāpana hiki ke hoʻololi ʻia a paʻakikī
Hoʻololi ʻia ka mea nano e hoʻomaikaʻi i ke kaomi
ke kū'ē a me ka hopena o ka huahana
5, ʻO ke kino valve mānoanoa no ke kū'ē hoʻopiʻi kiʻekiʻe
6, 100% kaomi ho'āʻo ma mua o ka lawe ʻana
7, Hoʻomaʻamaʻa kūikawā ʻia ke kino a me nā ʻāpana sealing no ka maikaʻi maikaʻi.
ʻO Eccentric butterfly valve he valve mana maʻamau, iʻikeʻia e ka hoʻolālā valve flap no ka hoʻolālā eccentric, i ka weheʻana a me ka pani pani hiki ke hana i ka valve sealing maikaʻi me ke kōkua o ka hoʻolālā eccentric. E pili ana i ka valve flap valve no ke axis symmetric.
Ke hoʻohālikelike ʻia me nā kīwaha butterfly maʻamau, ʻike ʻia nā ʻāpana butterfly eccentric e ka hoʻolālā paʻakikī a me ke kumu kūʻai kiʻekiʻe. Eia nō naʻe, i nā noi kūpono, ʻoi aku ka maikaʻi o ka hoʻokele mana a me ka hana hoʻopaʻa ʻana, ʻoi aku ka nui o ke kaomi kiʻekiʻe, ka wela kiʻekiʻe, ka viscosity kiʻekiʻe a me nā mea paʻakikī ʻē aʻe, ʻoi aku ka kaulana o ka hana ʻana o ka valve butterfly eccentric, e hoʻokō pono i ka mana kahe a me ke kaomi. hooponopono.
He aha ka pōmaikaʻi o ka valve butterfly eccentric?
1.small kahe kū'ē:
no ka mea, ua hoʻolālā ʻia ka spool o eccentric butterfly valve e ʻokoʻa ka centrifugally mai ka noho ma kahi mamao, i ka wā e kahe ai ka waena ma o ka valve, ʻoi aku ka pōkole o ke ala kahe ma mua o nā kiwi ʻē aʻe, no laila e hana i kahi kūʻē liʻiliʻi;
2.Reliable sealing:
I ka wā o ka pani ʻana o ka valve butterfly eccentric, e hoʻokumu ʻia kahi kaomi ʻoi aku ka nui ma waena o ka spool a me ka noho, hiki ke ʻike i ka sila ʻoi aku ka maikaʻi; ʻoiai i ka wehe ʻana, hilinaʻi nui ia i ka friction ma waena o ka spool a me ka noho e hōʻoia i ka sila.
3.Liilii puʻe poho:
eccentric butterfly valve me ka eccentric structure hiki ke hoʻololi i ke ala kahe waena i ka liʻiliʻi, no laila e hōʻemi ana i ke kū'ē a me ka poho puʻe.
