ʻO ka ʻokoʻa o ke ʻano o ka valve butterfly e hoʻokaʻawale i ʻehā ʻano o nā valve butterfly, ʻo ia hoʻi:kiwikā pulelehua concentric, kiwikā pulelehua eccentric hoʻokahi,kiwikā pulelehua eccentric pāluaa me ka valve pepeke eccentric ʻekolu. He aha ke kumumanaʻo o kēia eccentricity? Pehea e hoʻoholo ai i ka wā e hoʻohana ai i ka valve pepeke concentric, i ka wā e hoʻohana ai i ka valve pepeke eccentric hoʻokahi, i ka wā e hoʻohana ai i ka valve pepeke eccentric pālua a me ka valve pepeke eccentric ʻekolu? ʻAʻole maopopo loa ka nui o nā mea hoʻohana. E aʻo pū kākou.
Nā kiwikā pulelehua concentric, nā kiwikā pulelehua eccentric hoʻokahi, pāluanā kiwikā pepeke ʻano ʻēa ʻo nā kiwikā pepeke eccentric ʻekolu e hōʻike maoli ana i kahi kaʻina hana o ka wehe ʻana a me ka pani ʻana me ka hoʻoikaika liʻiliʻi a me ka emi ʻana o ka ʻaʻahu ma ka ʻili sila. Ma ka hoʻonohonoho ʻana i ke kūlana o ke koʻokoʻo wili o ka papa kiwikā pepeke, hiki ke hoʻololi ʻia nā kūlana sila a me ka wehe ʻana o ka kiwikā pepeke. Ma lalo o nā kūlana like, ke piʻi nei ka torque o ka kiwikā i ka wā e wehe ana ma ke kaʻina. Ke wehe ʻia ka kiwikā, ʻoi aku ka liʻiliʻi o ke kihi wili e pono ai no ka papa kiwikā e hoʻokaʻawale mai ka sila ma ke kaʻina.
ʻO ke ʻano hoʻonohonoho o ka valve butterfly concentric, ʻo ia ke kikowaena o ke kumu valve, ke kikowaena o ka papa butterfly a me ke kikowaena o ke kino valve ma ke kūlana like. Ma ke ʻano laulā, inā hiki ke hoʻohana ʻia nā valves butterfly concentric, pono e hoʻohana ʻia e like me ka hiki. No ka mea, ʻaʻole koi ke ʻano concentric i ka hana sila kiʻekiʻe ma ke ʻano o ka hoʻonohonoho ʻana a i ʻole ka hana, he huahana maʻamau ia. I mea e lanakila ai i ka extrusion, scraping, a hōʻoia i ka hana sila, ʻo ka noho valve o ka valve butterfly concentric ua hana ʻia me ka rubber a i ʻole PTFE a me nā mea elastic ʻē aʻe, ʻo ia ka valve butterfly sila palupalu. ʻO kēia ka mea e hoʻohana ai i nā valves butterfly concentric i nā palena mahana. I mea e hoʻoponopono ai i ka pilikia extrusion o ka papa butterfly a me ka noho valve, ua hana ʻia kahi valve butterfly eccentric hoʻokahi. ʻO kona ʻano hoʻonohonoho, ʻo ke kikowaena o ke kumu valve e ʻokoʻa mai ke kikowaena o ka papa butterfly.
ʻO ka valve pepeke eccentric pālua ka mea i hoʻohana nui ʻia. ʻO kona hiʻohiʻona hoʻonohonoho, ʻo ia ke kikowaena o ke koʻokoʻo o ke kumu valve e ʻokoʻa ana mai ke kikowaena o ka papa butterfly a me ke kikowaena o ke kino valve. ʻO ia ke ʻokoʻa mai nā kūlana kikowaena ʻelua, no laila ua kapa ʻia ʻo ia he valve pepeke eccentric pālua. He nui o lākou i sila ʻia me ka laina. Ke pani ʻia ka ʻili sila, aia ka friction ma waena o ka papa disc a me ka noho valve, a maikaʻi loa ka hopena sila. Loaʻa iā ia nā ʻano o kahi liʻiliʻi a me ke kaomi ikaika. Ma hope o ka wehe ʻana o ka valve, hiki i ka papa butterfly ke haki koke mai ka noho valve, kahi e hoʻopau nui ai i ka extrusion nui a me ke kahakaha ʻana ma waena o ka papa a me ka noho, e hōʻemi ana i ka mamao o ka wehe ʻana, e ʻaʻahu ana, a hoʻomaikaʻi i ke ola lawelawe o ka noho valve.
ʻO ke kolu o ka eccentric butterfly valve ma ke kumu o ka pālua eccentric butterfly valve. ʻAʻole he cone maikaʻi ke ʻano o ka hui sila, akā he cone oblique. ʻO ka hapa nui o lākou he ikaika pōkole a me ka sila ʻili. ʻO ke kumu o ka triple eccentric butterfly valve he ʻano ʻekolu ʻāpana. He concentric nā ʻāpana ʻelua o ke kumu o ka ʻekolu ʻāpana valve valve, a ʻo ke kikowaena o ke kikowaena ʻāpana e haʻalele ana mai ke axis o nā wēlau ʻelua ma kahi mamao waena, a ua kau ʻia ka papa butterfly ma waenakonu. ma luna o ke kumu. ʻO kēlā ʻano eccentric e hana i ka papa butterfly i ʻano eccentric pālua i ka wā e wehe piha ai, a hoʻokahi ʻano eccentric i ka wā e huli ai ka papa butterfly i ke kūlana pani. Ma muli o ka hopena o ke kumu eccentric, i ka wā e kokoke ana i ka pani ʻana, neʻe ka papa butterfly i kahi mamao i loko o ka ʻili cone sila o ka noho valve, a kūlike ka papa butterfly me ka ʻili sila o ka noho valve e hoʻokō i ka hana sila hilinaʻi. Hoʻoponopono ia i ka kūʻē ʻana he sila maikaʻi ʻole ka sila paʻakikī, a he hopena sila maikaʻi ka sila palupalu akā ʻaʻole kūpaʻa i ka mahana kiʻekiʻe.
I ka manawa e hoʻohana ai i ka valve butterfly concentric, i ka manawa e koho ai i ka valve butterfly eccentric pālua a i ʻole ka valve butterfly eccentric triple, hilinaʻi nui ia i nā kūlana hana a me ka waihona kālā.
