Cov Lus Nug Feem Ntau (FAQ) - Cryogenic Globe Valve (-196 ° C)
Q: Qhov txawv ntawm lub cryogenic globe valve thiab lub globe valve txheem yog dab tsi?
A: Cov li qub cryogenic muaj ntau yam tseem ceeb uas tsis pom muaj nyob rau hauv cov li qub txheem: lub kaus mom ntev nrog lub phaj ntws los tiv thaiv cov foob qia; kev kho mob cryogenic tob ntawm txhua yam khoom; cov ntaub ntawv rooj zaum tshwj xeeb (PCTFE, PEEK) rau qhov kub qis; cov pa phem tsawg; thiab kev sim ua haujlwm cryogenic yuav tsum tau ua ib qho BS 6364.
Q: Qhov kub tsawg kawg nkaus rau koj lub cryogenic globe li qub yog dab tsi?
A: Peb cov qauv cryogenic globe valves raug ntsuas rau -196 ° C kev pabcuam ib BS 6364. Rau cov kua hydrogen (-253 ° C) lossis kua helium (-269 ° C) kev pabcuam, peb muab cov qauv tsim tshwj xeeb.
Q: Kev kho mob cryogenic tob yog dab tsi thiab vim li cas nws thiaj xav tau?
A: Kev kho mob cryogenic tob yog cov txheej txheem ntawm kev txias cov khoom valve rau -196 ° C rau tsawg kawg 8 teev. Qhov no hloov pauv cov austenite khaws cia, txo cov kev ntxhov siab seem, thiab ua kom muaj kev ruaj khov ntawm qhov kub thiab txias.
