DI CI SS304 Pālua Papa Nānā 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.

ʻO ka valve nānā pālua-papa, he disc poepoe ʻelua-lobed i hoʻopaʻa ʻia ma ke kino valve me kahi ʻau pine. Aia ʻelua mau pūnāwai torsion ma ke ʻau pine. Hoʻokomo ʻia ka disc ma ka ʻili sila o ke kino valve, a kaomi ʻia ka pūnāwai e ke kaomi waena. ʻO ka papa butterfly, ke hoʻohuli ʻia ke kahe, pani i ka valve e ka ikaika puna a me ke kaomi waena. ʻO kēia ʻano valve nānā butterfly he ʻano wafer nui, liʻiliʻi ka nui, māmā ke kaumaha, hilinaʻi i ka sila ʻana, a hiki ke hoʻokomo ʻia i loko o nā pipeline ākea a me nā pipeline kū.
