ʻO ka Ductile Iron SS304 SS316 Non-return Swing Check Valve

ʻO ka valve nānā, i ʻike ʻia hoʻi he valve ala hoʻokahi, valve nānā, valve kaomi hope, ua wehe ʻia a pani ʻia kēia ʻano valve e ka ikaika i hana ʻia e ke kahe o ka medium ponoʻī i loko o ka pipeline, a no kahi valve aunoa. ʻO ka hana o ka valve nānā, ʻo ia ke pale ʻana i ke kahe hope o ka medium, ka hoʻohuli hope ʻana o ka pamu a me kāna mīkini hoʻokele, a me ka hoʻokuʻu ʻana o ka medium i loko o ka pahu. ʻO ka valve nānā pālua-papa kahi ʻano valve nānā maʻamau. Ma ke koho ʻana i nā mea like ʻole, hiki ke hoʻopili ʻia ka valve nānā wafer i ka wai, ka mahu, ka ʻaila i ka petrochemical, metallurgy, ka mana uila, ka ʻoihana māmā, ka meaʻai a me nā ʻoihana ʻē aʻe. , waikawa nitric, waikawa acetic, medium oxidizing ikaika a me urea a me nā media ʻē aʻe.

Hoʻohana ka valve nānā swing i kahi ʻano swing lima rocker i kūkulu ʻia. Hoʻokomo ʻia nā ʻāpana wehe a pani āpau o ka valve i loko o ke kino valve a ʻaʻole komo i loko o ke kino valve. Koe wale nō ka gasket sila a me ke apo sila i hoʻohana ʻia ma ka flange waena, ʻaʻohe wahi leakage holoʻokoʻa, e hoʻopau ana i ka hiki ke leakage valve. Hoʻohana ka pilina ma waena o ka lima rocker a me ka disc o ka swing check valve i kahi ʻano pilina poepoe, i loaʻa i ka disc kahi kekelē o ke kūʻokoʻa ma ka laulā o 360 degere, a loaʻa iā ia ka uku kūpono no ke kūlana trace. Hoʻohana nui ʻia ia i ka petroleum, kemika, lāʻau lapaʻau, mea hoʻouluulu, a me nā mea ʻē aʻe, uila a me nā pipelines ʻē aʻe. Kūpono no nā media maʻemaʻe, ʻaʻole kūpono no nā media i loaʻa nā ʻāpana paʻa a me ka viscosity kiʻekiʻe.
