ʻO ka lua eccentric butterfly valve flange type Large Size me Gearbox China hale hana me ke ʻano kiʻekiʻe
He aha ke ʻano flange lua eccentric butterfly valve
ʻO ke ʻano flange o ka pahu pahu lele eccentric pālua he 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.
ʻO ke ʻano flange o ka pahu pahu lele eccentric pālua, me ke apo sila i hoʻopaʻaʻia e ka uhi uhi, E hana ia i ka valve i ka nonstop fixing surface ma luna o ka pōʻai a hana i ka valve ʻaʻole i hoʻopā i ka noho i ka wā e wehe 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.
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.
