Nrog NSEN khoom dhau qhov kev xeem tim khawv raws li tus qauv BS 6364: 1984 los ntawm TUV. NSEN txuas ntxiv mus rau kev xa khoom ib pawg ntawm bi-directional sealing cryogenic npauj npaim valve.

Cryogenic valve siv dav hauv LNG kev lag luam. Nrog rau tib neeg them sai sai rau cov teeb meem ib puag ncig, LNG, hom zog huv no tau txais kev nyiam.

Vim tias qhov kub ntawm LNG nyob rau hauv qhov siab ib txwm yog -162 ℃, thiab nws muaj cov yam ntxwv ntawm kev kub hnyiab thiab tawg, lub qhov cua sov cryogenic tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm qhov kub qis, tab sis kuj yuav tsum xav txog kev tsim kev tiv thaiv hluav taws. Nws yog vim li no cov kev cai no uas kev nyab xeeb thiab kev ntseeg siab ntawm cov qhov cua sov cryogenic yuav siab dua li cov qhov cua ib txwm.

Qhov tseem ceeb tshaj, lub cev valve, phaj npauj npaim, qhov txuas ntxiv thiab cov khoom sab hauv yuav tsum tau ua tiav cryogenically ua ntej ua tiav kom tshem tawm qhov cuam tshuam ntawm kev hloov pauv theem. Txwv tsis pub, kev hloov pauv theem martensite yuav tshwm sim ntawm qhov kub qis, ua rau lub valve deformation, ua rau Lub valve xau.

Hom kev sib txuas rau cov khoom xa tuaj no yog flange thiab wafer, thiab cov khoom siv ntawm lub cev valve thiab disc yog CF8M. Cov khoom siv sealing tseem yog cov hlau khov kho sealing nplhaib tsim, nrog rau kev tso pa tawm tsawg.

Yog tias koj xav paub ntxiv lossis tau txais kev daws teeb meem rau koj qhov project, txais tos hu rau peb.
