Kev soj ntsuam thiab kev kho ntawm Internal Leakage thiab External Leakage ntawm Cryogenic li qub

1. Internal to ntawm cryogenic valve:

Kev tsom xam:Lub sab hauv to ntawm lub valve uas tsis tshua muaj kub yog tshwm sim los ntawm kev hnav lossis deformation ntawm lub nplhaib sealing.Thaum lub sij hawm sim ua haujlwm theem ntawm qhov project, tseem muaj me me ntawm impurities xws li xuab zeb thiab vuam slag hauv cov kav dej, uas yuav ua rau hnav lub valve sealing nto thaum lub valve qhib lossis kaw.

Kev kho mob:Tom qab lub valve nyob rau ntawm qhov chaw rau kev sim siab thiab kev teeb tsa, cov kua seem thiab cov impurities nyob rau hauv lub valve lub cev yuav tsum tau purged.Yog li ntawd, kev ntsuas kev saib xyuas ntawm qhov chaw muab los ntawm cov chaw tsim khoom thiab cov teeb meem xav tau kev saib xyuas hauv qhov chaw sim yuav tsum tau ua ke thaum lub sij hawm tsim kho.Qhia rau qhov chaw thiab nruj me ntsis tswj qhov zoo los pab txhawb kev tsim khoom, kev ua haujlwm thiab kev saib xyuas ntawm qhov project yav tom ntej.

2. Cov dej ntws ntawm cryogenic valve:

Kev tsom xam:Cov laj thawj rau cov dej ntws ntawm cov kua dej cryogenic tuaj yeem muab faib ua plaub yam hauv qab no:

1. Qhov zoo ntawm lub valve nws tus kheej tsis zoo txaus, nrog cov hlwv lossis lub plhaub tawg;

2. Thaum lub sijhawm kev teeb tsa, thaum lub valve txuas nrog lub flange siv rau lub raj xa dej, vim muaj cov khoom sib txawv ntawm cov khoom sib txuas thiab cov gaskets, tom qab nkag mus rau hauv nruab nrab hauv cov kav dej, nyob rau hauv qhov kub thiab txias ib puag ncig, cov ntaub ntawv sib txawv sib txawv. , ua rau kom so;

3. Txoj kev teeb tsa tsis raug;

4. Cov dej ntws tawm ntawm lub valve qia thiab ntim khoom.

 Cov txheej txheem txheej txheem yog raws li nram no:

1. Ua ntej tshaj tawm tsab ntawv ceeb toom, cov duab kos thiab cov qauv tsim los ntawm cov chaw tsim khoom yuav tsum tau lees paub thiab ua tiav raws sijhawm, thiab tus neeg saib xyuas lub Hoobkas yuav tsum sib txuas lus raws sijhawm.Cov khoom siv raw yuav tsum tau soj ntsuam nruj me ntsis, thiab RT, UT, PT yuav tsum tau ua raws li cov kev cai.tshuaj xyuas, thiab tsim ib daim ntawv qhia.Muab cov txheej txheem ntau lawm.Hauv cov txheej txheem tsim khoom yav tom ntej, yog tias tsis muaj qhov xwm txheej tshwj xeeb, kev tsim khoom yuav tsum tau ua nruj me ntsis raws li lub sijhawm nrog lav zoo thiab muaj nuj nqis, thiab kev tshuaj xyuas nruj yuav tsum tau ua ua ntej tawm hauv lub hoobkas.

2. Lub valve cim nrog cov kev taw qhia ntws yuav tsum tau them sai sai rau cov kev taw qhia ntws ntawm lub valve lub cev.Tsis tas li ntawd: Rau cov txheej txheem, nws yog ib qho tseem ceeb heev uas yuav tsum tau tswj thawj lub sij hawm ua ntej txias ntawm lub valve kom lub valve tuaj yeem ua kom txias tag nrho.Nws yog ib qho tsim nyog yuav tsum nquag xyuas seb cov phab ntsa sab hauv ntawm lub valve puas muaj cov kab nrib pleb, deformation thiab corrosion ntawm sab nrauv, tshwj xeeb tshaj yog rau qhov kub thiab txias.Lub valve ntawm qhov nruab nrab yog yooj yim rau thermal expansion thiab contraction.Rau lub valve nyob rau hauv hnyav tej yam kev mob xws li cavitation, nws yog tsim nyog los xyuas kom meej nws compressive zog, tsis kub thiab hnav tsis kam.
