Noho ʻia ʻo Double Eccentric Butterfly Valve
He aha nā kiwi lele lele eccentric pālua?
ʻO ka pāpaʻi kiʻi kiʻi luahe mea hoʻolālā hoʻolālā pālua offset hou me ka ʻenehana alakaʻi honua kiʻekiʻe.He ʻano kū hoʻokahi kēia ʻano kīpē butterfly me ka hana sealing hilinaʻi nui, nā kūlana hana ākea a me ka torque hana haʻahaʻa.
Hana ʻia ke apo hoʻopaʻa lua eccentric butterfly valve me ka elastomer kūpono i ka disc, hiki ke hoʻohana ʻia i ka noi unidirectional sealing, maʻamau i hoʻohana ʻia i ka wai a i ʻole ka wai wai.
He aha ka mea e ʻokoʻa ai mai nā ʻōhua butterfly ʻē aʻe a pau, ʻo ia ka papalua eccentric a i ʻole ʻelua offset disc design.
hiki iā ia ke neʻe aku i ka diski mai ka noho e hoʻemi ana i ka torque holo a me ka ʻaʻahu o ka noho, ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana i nā valve concentric butterfly.
ʻAʻole i hoʻopā ka pahu i ka noho i ka wā e hāmama loa ai.ʻO kēia hoʻolālā e hoʻemi i ka hakakā ʻana o ka noho a no laila e hoʻolōʻihi i kona ola.Ma ka noi maʻamau, ua kaupalena ʻia kēia ʻāpana ʻāpana kaulike bi-directional i ka papa 150.
ʻO nā hiʻohiʻona nui o NORTECH pālua eccentric butterfly valves noho?
Noho kūpaʻaHoʻopaʻa ʻia nā kiwi lele eccentric pālua
Kūlana hoʻolālā: BS EN593
He alo a he alo ka lōʻihi : EN558-1/ISO5752 moʻo 14& ISO5752 moʻo 13

No ke aha e koho ai iā mākou?
Qka hāʻawi ʻana i ka uick, mākaukau no ka hoʻouna ʻana i nā wiki he 1-4, me nā waihona noʻonoʻo o nā ʻūhā lele a me nā ʻāpana.

Main feautres o Hoʻopaʻa ʻia nā kiwi lele eccentric pālua:
ʻOi aku ka lōʻihi o ka lawelawe ʻana ma muli o ka diski hili ʻia
Hoʻokuʻu ʻia ka haʻalulu ma ka disc ma hope o kekahi mau degere o ka wehe ʻana e hōʻemi ana i ka ʻaʻahu ʻana o ke sila diski.Eia kekahi, ʻo ka hoʻolālā e hōʻemi i ka paʻi ʻana o ka hoʻopaʻa ʻana e hōʻoia ai i nā torque hana haʻahaʻa.
Nā hoʻolālā noho māhoe
ʻO ka hoʻolālā noho hoʻohui i ka mīkini a me ka epoxy i uhi ʻia i ka ductile hao i hoʻohui ʻia i loko o ke kino.ʻO ka hoʻolālā noho kila kila he apo noho hoʻololi o ke kila kila i hoʻopaʻa ʻia me ka O-ring e pale aku i ka leakages ma lalo o ke apo noho.
Nā hiʻohiʻona hoʻolālā shaft
Hiki ke hoʻololi ʻia ka shaft sealing ma lalo o ke kaomi e hiki ai i ka mālama maʻalahi.Hoʻopaʻa paʻa ka paʻa ʻana o ka EPDM mai loko a i waho, a pale aku nā sila NBR i nā haumia a me nā wai mai waho.
Hoʻopaʻa ʻia ke sila diski no ka hana kiʻekiʻe
Hoʻokumu ʻia ka sila diski e hoʻopaʻa i ka hoʻoponopono ʻana ma ke kūlana kūpono e hāʻawi ana i kahi hana hilinaʻi loa.ʻO ka maikaʻi o ka lāʻau lapaʻau maikaʻi e hiki ai ke hōʻemi i ka nui o ka pahu e hōʻoia ai i nā torque pani haʻahaʻa.Ua ʻae ʻia ka sila EPDM e ACS a me WRAS.
Paʻa ʻaoʻao ʻelua
ʻO nā kiwikā he bi-directional a uni-directional ma ke koi.
Sila hoʻololi ʻia ma ka disk me ka hoʻopaʻa paʻa ʻole
Loaʻa i ka hoʻolālā hoʻololi ʻelua ʻo Ddouble i ka liʻiliʻi o ka noho noho, haʻahaʻa torque
ʻO ka liʻiliʻi liʻiliʻi e hōʻoia i ke ola hoʻohana lōʻihi loa
apo hoʻopaʻa paʻa hou
Kino pena epoxy&disc
ISO 5211 flange luna no nā hana like ʻole
Zero leakage ma nā ʻaoʻao ʻelua
Ke ʻano o ka hana ʻana no Double Eccentric Butterfly Valve e noho ana
no ka meaHoʻopaʻa ʻia nā kiwi kīpē eccentric pālua, hoʻolako mākou
ʻO ka hana pahu pahu lima, Pneumatic actuator, electric actuator, a me hydraulic acatuators no kāu koho.
ʻO nā kikoʻī kikoʻī o NORTECH pālua eccentric butterfly valves noho?
