ʻO ka kiwikā pulelehua i loko o ka hoʻonohonoho papa sila palupalu a me ka hoʻolauna hana

Hoʻohana nui ʻia ka valve butterfly i ke kūkulu ʻana i ke kūlanakauhale, ka petrochemical, ka metallurgy, ka mana uila a me nā ʻoihana ʻē aʻe i loko o ka pipeline waena e ʻoki a hoʻoponopono paha i ke kahe o ka mea hana maikaʻi loa. ʻO ke ʻano o ka valve butterfly ʻo ia ka ʻāpana wehe a pani kūpono loa i loko o ka pipeline, ʻo ia ke kuhikuhi hoʻomohala o nā ʻāpana wehe a pani pipeline o kēia lā. Loaʻa iā mākou ka valve butterfly sila palupalu laina waena, kahi i hoʻohana nui ʻia i ka mahana maʻamau, nā kūlana hana haʻahaʻa haʻahaʻa, e like me ka lako wai a me ka hoʻokahe wai, nā papahana mālama wai, ke kūkulu ʻana i ke kūlanakauhale a me nā ʻoihana ʻē aʻe. ʻO ka mea aʻe e hoʻolauna nui nei i ka valve butterfly eccentric hoʻokahi, ka valve butterfly eccentric pālua a me nā huahana valve butterfly eccentric ʻekolu.

ʻO ka mea mua, ʻo ke ʻano eccentric hoʻokahi okiwikā pepeke sila palupalu, ʻo ka mānoanoa o ka ʻāpana sila noho a i ʻole ka papa pepeke o ke kuhikuhi o ka laina like a me ke kikowaena o ka wili ʻana o ke kumu valve eccentric, i ka wā e wehe ai ka valve pepeke, e neʻe mālie ka ʻili sila papa pepeke mai ka ʻili sila noho valve. I ka wili ʻana o ka papa pepeke i 20 ~ 25 °, e hoʻokaʻawale loa ʻia ka ʻili sila papa pepeke mai ka ʻili sila noho valve, i ka wā e wehe ai ka valve pepeke, ua hoʻemi nui ʻia ka ʻaʻahu mechanical a me ka extrusion ma waena o nā ʻili sila ʻelua, i hiki ke hoʻomaikaʻi ʻia ka hana sila valve pepeke. Hilinaʻi nui kēia hoʻolālā i ka deformation elastic i hana ʻia e ka extrusion ma waena o ka papa pepeke a me ka noho valve e hōʻoia i ka sila ʻana o ka valve pepeke.

Ma ke kumu o ka valve pepeke eccentric hoʻokahi, ua hoʻokaʻawale ʻia ke kikowaena wili o ka papa pepeke mai ke kikowaena o ke ala kahe valve, ka mea e hana ai i ka hopena cam o ka valve pepeke i ka wā o ke kaʻina wehe, i hiki ke hoʻokaʻawale ʻia ka ʻili sila o ka papa pepeke mai ka ʻili sila o ka noho valve ma mua o ka ʻano eccentric hoʻokahi. Ke wili ka papa pepeke i 8° ~ 12°, ua hoʻokaʻawale loa ʻia ka ʻili sila o ka papa pepeke mai ka ʻili sila o ka noho valve. ʻO ka hoʻolālā ʻana o kēia ʻano e hōʻemi nui i ka ʻaʻahu mechanical a me ka extrusion deformation ma waena o nā ʻili sila ʻelua, kahi e hoʻomaikaʻi ai i ka hana sila o ka valve pepeke.

A ma ke kumu okiwikā pulelehua eccentric pālua, ʻo ka laina waena o ka ʻili sila noho e hana i kahi eccentricity angular me ka laina waena o ka valve, kahi e hoʻokaʻawale koke ai ka ʻili sila o ka papa butterfly mai ka ʻili sila noho i ka manawa o ka wehe ʻana i ke kaʻina hana o ka wehe ʻana o ka papa butterfly, a hoʻopili wale a kaomi i ka ʻili sila noho i ka manawa o ka pani ʻana. ʻO kēia hui kūikawā o ka eccentricity e hoʻohana piha i ka hopena cam, hoʻopau loa i ka friction mechanical a me ka abrasion ma waena o nā ʻili sila ʻelua o ka vice sila valve butterfly i ka wā e wehe ai a pani ai ka valve, a wehe i ka hiki ke abrasion a me ka leakage. Hoʻololi ʻia ka sila extruded i sila torque, a ua ʻike ʻia ka hoʻoponopono ʻana o ke kaomi sila ma ka hoʻoponopono ʻana i ka torque hoʻokele waho, i hoʻomaikaʻi nui ʻia ka hana sila a me ke ola lawelawe o nā valve butterfly sila ʻekolu eccentric.

Eia kekahi, ʻo Tianjin Tanggu Water Seal Valve Co., Ltd. he ʻenehana holomua i ka noho ʻana o ka laholio e kākoʻo ana i nā ʻoihana, ʻo nā huahana he noho kūpaʻa wafer butterfly valve, lug butterfly valve, pālua flange concentric butterfly valve, kaulike valve, wafer dual plate check valve,Kiwikā Hoʻokuʻu Ea, Y-Strainer a pēlā aku. Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou i ka hāʻawi ʻana i nā huahana papa mua e hoʻokō ana i nā kūlana ʻoihana kiʻekiʻe loa. Me kā mākou ākea o nā valves a me nā mea hoʻopili, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kāhea mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou huahana a pehea e hiki ai iā mākou ke kōkua iā ʻoe.
