Dab tsi yog tus qauv ntsuas rau cryogenic li qub?
Qhov ntsuas ntawm cryogenic valve feem ntau yog tsom rau cov khoom ua tau zoo, cov ntsiab lus tsis khov, cov ntsiab lus kev xeem, cov ntsiab lus tshwj xeeb yog raws li hauv qab no:
1. Cov khoom xeem ntawv
Cov Huab Cua Nrawm Kuaj:
Kev xeem lub rooj zaum yog nqa tawm hauv qhov chaw kub tsawg (piv txwv li {}}} Cov qib siab), thiab kev thov nyiaj ntau dua lossis sib npaug ntawm cov nominal siab los ua kom tsis muaj xau.
Li qub yuav tsum tau ua ntej txias rau lub hom phiaj nitrogen kom paub tseeb qhov tseeb ntawm kev sib khi ua yuam kev ntawm kev sib luag tsawg dua lossis sib npaug}. 01 hli).
Cov khoom siv tsawg tshaj cuam tshuam:
Charpy V-Motch cuam tshuam rau ntawm lub cev valve, lub rooj zaum thiab lwm yam tseem ceeb ua haujlwm ntau dua lossis sib npaug kom paub tias cov khoom tsis yooj yim ntawm qhov kub tsawg.
Siab DOV TOV:
Plam lub zog kev ntsuas ntsuas ntawm chav tsev kub, siab ntau dua lossis sib npaug rau 1.5 zaug ntawm nominal siab lossis tsis muaj kev lom zem.
Qhov kub thiab txias mus kuaj:
Simulate cov kev ua haujlwm hnyav dhau los ntawm kev ua kua nitrogen sai ua kom txias thiab rewarming kom paub tseeb qhov kev ruaj ntseg ntawm valve ntawm valve.
2. Txheem lub hauv paus thiab cov ntawm daim ntawv thov
Mss sp -134:
MSS SP -134: txhais cov ntsiab lus ntawm cov khoom siv hluav taws xob tsawg (fur degree} {
Mil-std -810 f:
MIL-STD -810 f yog ib puag ncig kev sim ntawm cryogenic li qub nyob rau hauv cov tub rog teb, suav nrog qhov kub thiab txias thiab lwm yam kev sib xyaw.
ASTM D 7437-07:
Tsawg-kub ua tau kuaj xyuas rau cov ntaub ntawv tsis yog metallic (piv txwv li PTFE, yoog raws li cov kab mob tsis kam mus rau qhov tsis txaus ntshai thiab hnav.
3. Kuaj cov txheej txheem thiab cov xwm txheej
Kuaj nruab nrab:
Ua kua nitrogen (-196 degree) lossis kua argon ({}}} degree) yog siv los simule huab cua sov ib puag ncig.
Cov Qauv Txheej Txheem:
Lub pob hluav taws xob yuav tsum yog tsim los ua lub caj dab ntev kom ntseeg tau tias qhov kub ntawm lub thawv stuffing loj dua los yog sib npaug}} degree kom tsis txhob khov.
Hlau + cov hlau tsis muaj hlau yuav tsum tau saws ntawm valve lub rooj thiab pob / rooj vag los txhim kho kev ntseeg tau ntawm kev ntseeg tau kub.
Kev Tshawb Fawb Ua Haujlwm:
Ntsuam xyuas qhov qhib thiab kaw lub zog ntawm lub valve raws li cov haujlwm ua haujlwm tsawg, uas yuav tsum tau ua haujlwm hloov tau thiab tsis muaj zog.
4. Cov cai tshwj xeeb thiab kev txiav txim plaub
Cov Khoom Xaiv:
Lub cev siv hluav taws xob feem ntau yog siv LCB, LC3 thiab lwm cov pa roj ntsha (POB tsawg
Daim Ntawv Qhia Xeem:
Yuav tsum tau sau lub sijhawm ua ntej txias, kev tsis sib xws, to thiab lwm cov ntaub ntawv tseem ceeb, thiab raws li MSS sp -134 kom txiav txim siab ua raws.
Ntsiab lus: US cryogenic valve tus qauv ntsuas yog raws MSS sp {{0} Taug kev cov kev cuam tshuam, uas yog qhov tsim nyog rau LNK, tshuaj lom neeg thiab lwm yam kev ua haujlwm hnyav.
