Nā ʻenehana Koho Valve

Nā ʻenehana koho valve

1, ka valve check (aetv One-way valve): pili maʻamau i ka media maʻemaʻe, ʻaʻole no ka loaʻa ʻana o nā ʻāpana paʻa a me ka viscosity o ka waena.

2, ma hope o ka pahu haʻahaʻa haʻahaʻa no DN50mm (aetv One-way valve) :, pono e hoʻohana i ka valve butterfly, e nānā i ka valve a me ka diaphragm vertical lift check valve; No ka DN oi aku ma mua o 200mm, emi iho ma lalo o 1200mm o ka haʻahaʻa puʻe nānā kiwikā, non-hoʻi kiwikā e koho i ka lole spherical; no ka DN ʻoi aku ma mua o 50mm, emi iho ma mua o 2000mm o ke kaomi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, butterfly valve a me ka diaphragm pono e hoʻohana i nā kiwi loiloi.

3, ʻo ka valve diaphragm kūpono no ka maʻalahi o ka hana ʻana i ka hāmare wai i ka pipeline, hiki ke hoʻopau ʻia ka membrane upstream medium i hana ʻia i ka wā e hāmama ai ka wai, akā ma nā palena wela a me ke kaomi, maʻamau i ka lumi wela i ka pipeline haʻahaʻa haʻahaʻa.
