Nechigadzirwa cheNSEN pfuura bvunzo yeuchapupu maererano neyakajairwa BS 6364: 1984 neTUV.NSEN inoenderera mberi nekuunza batch yebi-directional sealing cryogenic butterfly valve.

Cryogenic valve inoshandiswa zvakanyanya muindasitiri yeLNG. Nevanhu vanobhadhara zvakanyanya uye zvakanyanya kutarisisa nyaya dzezvakatipoteredza, LNG, rudzi urwu rwesimba rakachena rinofarirwa.

Sezvo tembiricha yeLNG iri pasi pekumanikidzwa kwakajairwa iri -162 ℃, uye iine hunhu hwekupisa uye kuputika, iyo cryogenic tembiricha vharafu haizadzise chete zvinodikanwa zve tembiricha yakaderera yekushandisa tembiricha, asi inodawo kufunga nezve dhizaini yekudzivirira moto.Izvo chaizvo nekuda kwezvinodikanwa izvi kuti kuchengetedzwa uye kuvimbika kwemavharuvhu e cryogenic kuchave kwakakwirira kupfuura mavharuvhu akajairwa.

Zvinotonyanya kukosha, muviri wevharuvhu, butterfly plate, chikamu chekuwedzera uye zvikamu zvemukati zvinofanirwa kugadziridzwa cryogenically isati yapedza kubvisa pesvedzero yekuchinja kwechikamu.Zvikasadaro, martensite phase shanduko ichaitika pane yakaderera tembiricha, zvichikonzera deformation yevhavha, zvichikonzera kuti Ivhavha iri kubuda.

Mhando yekubatanidza yekutakura iyi ndeye flange uye wafer, uye zvinhu zvemuviri wevharuvhu uye disc ndeye CF8M.Iyo yekuisa chisimbiso ichiri yese simbi yakasimba yekuisa chisimbiso mhete dhizaini, ine yakaderera emission kurongedza stem chisimbiso.

Kana uchitarisira kudzidza zvakawanda kana kuwana mhinduro yeprojekiti yako, unogamuchirwa kuti ubate nesu.
