Paglalarawan ng Produkto

Ang cryogenic swing check valve ay ginagamit sa management system ng cryogenic liquid storage at transport equipment upang pigilan ang backflow ng cryogenic media. Ito ay may mga katangian ng flexible switching at maaasahang sealing.
Kapag ang daluyan ay dumadaloy sa tinukoy na direksyon, ang balbula disc ay binuksan sa pamamagitan ng puwersa ng daluyan; kapag ang medium ay umaagos pabalik, dahil sa self-weight ng valve disc at ang reaction force ng medium, ang valve disc at ang valve seat sealing surface ay mahigpit na nakasara, at sa gayon ay nakakamit ang layunin ng pagpigil sa backflow ng medium.
Naaangkop na media: methane, liquefied natural gas, hexene, carbon dioxide, likidong ammonia, likidong oxygen, likidong nitrogen, likidong hydrogen at iba pang cryogenic media.
