Centerline butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve a me triple eccentric butterfly valve, ua hoʻololi kēia mau ʻano o nā ʻano ʻano o nā ʻano ʻano o nā ʻano ʻano o nā ʻano ʻano o nā ʻano ʻano o nā ʻano o nā ʻano ʻano o nā ʻano o nā ʻano o nā ʻano ʻano o nā ʻano ʻano o nā ʻūhā lele e hoʻololi i ka hoʻopaʻa ʻana a me ka wehe ʻana i ke kūlana ma o ka hoʻonohonoho ʻana i ke kūlana o ka pahu pahu pahu.
Ma lalo o nā kūlana hoʻokahi, ʻoi aku ka liʻiliʻi o ke kihi rotation no ka haʻalele ʻana o ka pā valve mai ka sila i ka wā e wehe ʻia ai ka valve ma mua o ka mea ʻē aʻe, a ua hoʻokau ʻia ka valve i ka torque ʻoi aku ka nui ma mua o kēlā me kēia wehe.
ʻEkolu kiwi lele eccentric:
No ka pale wela kiʻekiʻe, pono e hoʻohana i kahi sila paʻakikī, akā nui ka nui o ka leakage;no ka leakage ʻole, pono e hoʻohana ʻia kahi sila palupalu, akā ʻaʻole kū i ka wela kiʻekiʻe.I mea e lanakila ai i ka kuee o ka lua eccentric butterfly valve, ka butterfly valve i eccentric no ke kolu o ka manawa.ʻO ka puʻuwai ʻekolu i kapa ʻia ʻo ke ʻano o ka hui hoʻopaʻa ʻana ʻaʻole ia he cone maikaʻi, akā he cone slanted.ʻO ka hiʻohiʻona kūʻokoʻa o ka valve triple eccentric butterfly valve ʻo ia ka valve kahi i hoʻokomo ʻia ai ka papa pelelele he ʻano ʻāpana ʻekolu ʻāpana.He concentric nā ʻāpana ʻelua o ka ʻāpana ʻāpana ʻekolu, a ʻo ka laina waena o ka ʻāpana waena e hoʻopau ʻia mai nā kihi ʻelua o ke axis e kahi mamao waena.Hoʻokomo ʻia ka pā ma ka ʻāpana waena waena.ʻO ia ʻano hana eccentric e lilo ai ka disc i ʻelua eccentric i ka wā e hāmama loa ai ka disc, a lilo i hoʻokahi eccentric ke hoʻohuli ʻia ka disc i ke kūlana pani.Ma muli o ka hana o ka eccentric shaft, i ka wā e kokoke ana i ka pani ʻana, neʻe ia i kahi mamao i loko o ka ʻili cone sealing o ka noho valve, a hoʻohālikelike ka pā papale i ka ili hoʻopaʻa o ka noho valve e hoʻokō ai i ka sila hilinaʻi.
ʻO ka lua pele eccentric valve:
Hoʻokumu ʻia i ka valve eccentric butterfly valve, ʻo ia ka valve offset pālua i hoʻohana nui ʻia.ʻO kāna hiʻohiʻona hoʻolālā, ʻo ia ka neʻe ʻana o ke kikowaena o ke kumu valve mai ke kikowaena o ka disc a me ke kikowaena o ke kino valve.ʻO ka hopena o ka lua eccentricity e hiki ai i ka disc ke hoʻokaʻawale koke mai ka noho valve ma hope o ka wehe ʻana o ka valve, kahi e hoʻopau nui ai i ka extrusion excessive pono ʻole a me ka ʻoki ʻana ma waena o ka disc a me ka noho valve, hoʻemi i ka pale ʻana, hoʻemi i ka lole, a hoʻomaikaʻi i ka valve noho noho hana ola.
ʻO ka valve lele eccentric hoʻokahi:
I mea e hoʻoponopono ai i ka pilikia extrusion ma waena o ka disc a me ka noho valve o ka valve butterfly concentric, ua hana ʻia ka valve eccentric butterfly hoʻokahi.Axial kikowaena, dispersion, hoemi i ka excessive extrusion o ka luna a me ka lalo welau o ka pā a me ka valve noho.
Kiwi lele lele waena
ʻO ka hiʻohiʻona hoʻolālā o ka valve butterfly laina waena, ʻo ia ke kikowaena o ke kumu, ke kikowaena o ka disc a me ke kikowaena o ke kino valve i ke kūlana like.No ka mea, ʻo ka papa pelelele a me ka noho valve i nā manawa a pau i kahi kūlana o ka extrusion a me ka ʻoki ʻana, ʻoi aku ka mamao o ke kūʻē ʻana a wikiwiki ka lole.Hoʻolālā maʻalahi a maʻalahi.I mea e lanakila ai i ka extrusion a me ka scratching e hōʻoia i ka hana hoʻopaʻa ʻana, ua hana maoli ʻia ka noho valve me nā mea elastic e like me ka rubber a i ʻole PTFE.
