- Cov npauj npaim qis qis tuaj yeem ua haujlwm hauv thaj tsam qis dua -29 degree (-20 degree F) thiab tuaj yeem tswj qhov kub thiab txias li qis li -196 degree ({4}} degree F) hauv cov ntawv thov cryogenic .
- Cryogenic npauj npaim valve lub cev, qia liner tsim yuav tsum:
1. cryogenic valve plhaub qauv duab. Kev xaiv cov ntaub ntawv yog qhov tseeb lossis tsis yog ntawm seb lub valve tuaj yeem ua haujlwm tau zoo thiab ntseeg tau muaj qhov tseem ceeb heev, cov yam ntxwv ntawm npauj npaim li qub thiab lub ntiaj teb li qub, lub rooj vag li qub, piv rau tsis tsuas yog zam cov duab ntawm qhov tsis sib xws, lub plhaub phab ntsa tuab yog tsis zoo li qub, nyob rau hauv qhov qis-kub txias shrinkage, kub ntxhov siab tshwm sim los ntawm lub deformation, tab sis kuj vim lub npauj npaim valve yog me me, cov duab ntawm lub valve lub cev sab laug thiab txoj cai yog yeej symmetrical, thiab yog li lub tshav kub muaj peev xwm yog me me. ; pre-txias noj kuj yog me me; cov duab ntawm cov cai Thiab pab txhawb lub valve txias ntsuas.
2. qhov kev xaiv ntawm qia bushing: qee qhov qis-kub npauj npaim valve nyob rau hauv kev ua haujlwm, lub valve rotating qhov chaw ntawm cov nplaum, tom phenomenon tshwm sim los ntawm lub sij hawm mus rau lub sij hawm, lub ntsiab yog vim li cas: khub ntawm cov khoom xaiv yog tsis tsim nyog, tawm hauv ib tug txias sib txawv. me me dhau lawm, nrog rau kev ua tiav precision tsis yog vim li cas. Nyob rau hauv txoj kev loj hlob ntawm qis-kub li qub, ib tug series ntawm kev ntsuas los tiv thaiv cov phenomenon saum toj no. Ntawm lub valve qia, lub qis liner tau xaiv nrog me me coefficient ntawm kev sib txhuam thiab nws tus kheej-lubricating kev ua tau zoo ntawm SF-1 hom sib xyaw bearings, uas tuaj yeem siv rau qee qhov kev xav tau tshwj xeeb ntawm cov cua kub qis. Hlau-sealed npauj npaim valve muaj cov yam ntxwv uas qee qhov zoo tib yam li qub tsis muaj, tshwj xeeb tshaj yog cov dej ntws me me, kev ruaj ntseg sealing, qhib thiab kaw sai, kev pab lub neej ntev thiab lwm yam. Peb eccentric hlau-sealed npauj npaim valve yog los ntawm deformation ntawm lub nplhaib elastic kom ua tiav sealing, thiab yog li tsis tas yuav cia siab rau nruab nrab quab yuam, yog li nws tuaj yeem siv rau ob txoj kev sib khi.
