Butterfly valve i loko o ka papa hana sila palupalu a me ka hoʻolauna hana

Hoʻohana nui ʻia ka valve Butterfly i ke kūkulu ʻana i ke kūlanakauhale, petrochemical, metallurgy, mana uila a me nā ʻoihana ʻē aʻe i ka pipeline medium e hana ʻoki a hoʻoponopono i ke kahe o ka mea maikaʻi loa. ʻO ka ʻōnaehana ʻo Butterfly valve ponoʻī ʻo ia ka mea kūpono loa i ka wehe ʻana a me ka pani ʻana i nā ʻāpana i ka pipeline, ʻo ia ke kuhikuhi hoʻomohala o ka wehe ʻana a me nā ʻāpana pani o kēia lā. Loaʻa iā mākou ka laina waena maʻamau o ka pahu lele lele, ka mea 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 māla ʻē aʻe. ʻO ka mea aʻe ka mea nui e hoʻolauna i ka valve eccentric butterfly valve, double eccentric butterfly valve a me nā huahana triple eccentric butterfly valve.

ʻO ka mea mua, ʻo ka hoʻolālā eccentric hoʻokahi okiwi lele lele sila, noho sila kea-pauku a papa pelekane mānoanoa o ke kuhikuhi o ka equidistant laina a me ke kikowaena o ka rotation o ka pahupahu kumu pili eccentric, no laila, i ka pepeke kiwikā i loko o ke kaʻina o ka wehe ana, ka papa peʻapeʻa sealing ili lohi mai ka kiwikā. ili hoʻopaʻa noho. Butterfly plate rotation to 20 ~ 25 °, ʻo ka butterfly plate sealing surface i hoʻokaʻawale loa ʻia mai ka noho valve sealing surface, no laila e hoʻemi nui ʻia ka valve butterfly i ka wehe ʻana, ka pili mechanical a me ka extrusion ma waena o nā mea hoʻopaʻa ʻelua. hiki ke hoʻomaikaʻi ʻia ka hana hoʻopaʻa ʻana o ka valve butterfly. Ke hilinaʻi nui nei kēia hoʻolālā i ka deformation elastic i hoʻokumu ʻia e ka extrusion ma waena o ka pā butterfly a me ka noho valve e hōʻoia i ka sila ʻana o ka valve butterfly.

Ma ke kumu o ka valve eccentric butterfly hoʻokahi, ua hoʻoneʻe ʻia ke kikowaena o ka papa butterfly mai ka laina waena o ke ala kahe o ka valve, e hana ai i ka hopena cam i ka wā o ka wehe ʻana, i hiki ke hoʻokaʻawale ʻia ka ʻili o ka papa butterfly. ʻoi aku ka wikiwiki o ka hoʻopaʻa ʻana o ka noho valve ma mua o ka hoʻolālā eccentric hoʻokahi. I ka wā e hoʻololi ai ka papa pelelele i 8 ° ~ 12 °, ua hoʻokaʻawale loa ʻia ka ʻili hoʻopaʻa ʻana o ka pā lele mai ka ʻili hoʻopaʻa o ka noho valve. ʻO ka hoʻolālā ʻana o kēia hoʻolālā e hoʻemi nui i ka ʻaʻahu mechanical pili a me ka deformation extrusion ma waena o nā papa sila ʻelua, kahi e hoʻomaikaʻi ai i ka hana sealing o ka valve butterfly.

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

Ma waho aʻe o kēia, ʻo Tianjin Tanggu Water Seal Valve Co., Ltd. he ʻenehana holomua ʻenehana e noho ana i nā ʻoihana e kākoʻo ana i nā ʻoihana, ʻo nā huahana ke kūpaʻa noho wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, balance valve, wafer dual plate check valve,Kiwi hoʻokuʻu ea, Y-Srainer a pēlā aku. Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i nā huahana papa mua e kū ana i nā kūlana ʻoihana kiʻekiʻe. Me kā mākou ākea ākea o nā valves a me nā pono, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kelepona 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.
