Nrog rau kev siv dav dav ntawm cov roj av, cov roj av liquefied thiab lwm lub zog hauv kev lag luam thiab pej xeem kev lag luam, lub luag haujlwm ntawm qhov kub tsis tshua muaj pneumatic thaum muaj xwm ceev shutoff valve hauv kev tiv thaiv kev nyab xeeb yog qhov tseem ceeb dua. Nyob rau hauv ib puag ncig uas tsis tshua muaj kub, cov pa pneumatic thaum muaj xwm ceev kaw-off valve feem ntau tsis tuaj yeem ua haujlwm zoo, yog li tsim thiab tsim khoom.Tsawg kub pneumatic thaum muaj xwm ceev kaw-off valve tau ntsib ntau yam kev nyuaj. Kab lus no yuav tshawb nrhiav cov kev cov nyom no thiab qhia qee qhov kev daws teeb meem kom muaj kev nyab xeeb ua haujlwm nyob rau hauv qhov kub thiab txias.
Ua ntej, xaiv cov khoom siv nyob rau hauv qhov kub thiab txias ib puag ncig
Nyob rau hauv qhov kub thiab txias ib puag ncig, lub cev lub cev ntawm cov khoom yuav hloov, xws li lub zog, toughness, hardness, thiab lwm yam, yuav raug txo. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov ntaub ntawv tsim nyog rau qhov kub thiab txias ib puag ncig. Rau qhov kub-kub pneumatic thaum muaj xwm ceev txiav tawm valve, lub ntsiab yuav tsum tau xav txog kev xaiv cov ntaub ntawv xws li lub cev valve, valve cover, valve qia thiab sealing cov ntaub ntawv.
Lub valve lub cev thiab lub hau npog yuav tsum tau tiv thaiv kev sib koom ua ke ntawm kev kub siab thiab qis kub, yog li nws yog ib qho tsim nyog yuav tsum xaiv cov khoom siv nrog lub zog siab, siab tawv thiab zoo kub tsis kam, xws li cov pa roj carbon tsawg, stainless hlau thiab lwm yam. Lub qia valve yuav tsum muaj lub zog txaus thiab hnav tsis kam, thaum txiav txim siab qhov tseeb ntawm nws txoj kev sib koom tes nrog lub valve lub cev kom ntseeg tau tias kev sib khi ntawm lub valve. Cov ntaub ntawv sib khi yuav tsum muaj qhov kub thiab txias tsis zoo thiab kev ruaj ntseg tshuaj, xws li roj hmab fluorine, silicone roj hmab thiab lwm yam.
2. sealing tshuab nyob rau hauv ib puag ncig uas tsis muaj kub
Nyob rau hauv ib puag ncig uas tsis tshua muaj kub, qhov hardness thiab toughness ntawm cov khoom sealing yuav raug txo, uas ua rau poob ntawm sealing kev ua tau zoo. Yog li ntawd, nyob rau hauv kev tsim ntawm low-temperature pneumatic thaum muaj xwm ceev kaw-off valve, tshwj xeeb sealing tshuab yog xav tau los xyuas kom meej sealing kev ua tau zoo.
Ib txoj kev sib khi zoo sib xws yog siv cov qauv foob ob npaug, uas yog, lub nplhaib hlau foob tau muab tso rau nruab nrab ntawm lub rooj zaum thiab lub qia kom tsim tau ob lub foob. Cov qauv no tuaj yeem tiv thaiv qhov xau ntawm qhov nruab nrab thiab txhim kho kev sib khi ntawm lub valve. Tsis tas li ntawd, txhawm rau tiv thaiv cov pob txha lov ntawm lub valve kav hauv qhov chaw kub tsawg, lub valve kav cov pa tiv thaiv lub tes tsho thiab lwm yam kev siv thev naus laus zis tuaj yeem siv tau.
Thib peb, cov txheej txheem tsim khoom nyob rau hauv ib puag ncig kub tsawg
Ntawm qhov kub thiab txias, cov txheej txheem tsim khoom ib txwm raug cuam tshuam, yog li yuav tsum muaj cov txheej txheem tsim khoom tshwj xeeb. Piv txwv li, hauv kev tsim cov pneumatic kub ceev kaw-off li qub, cov txheej txheem kev kho cryogenic tuaj yeem siv los txhim kho qhov kev ua haujlwm kub ntawm cov khoom. Tsis tas li ntawd, thaum lub sij hawm ua cov khoom, cov cuab yeej tshwj xeeb thiab cov cuab yeej siv tshuab yog xav tau los xyuas kom meej kev ua tiav thiab qhov zoo ntawm qhov chaw.
Kev tsim thiab tsim khoom ntawm qhov kub thiab txias pneumatic thaum muaj xwm ceev shut-off valve ntsib ntau yam teeb meem, tab sis ntev li ntev raws li kev ntsuas tau zoo nyob rau hauv kev xaiv cov khoom, sealing technology, manufacturing txheej txheem, thiab lwm yam, nws muaj peev xwm xyuas kom meej nws kev nyab xeeb kev ua tau zoo nyob rau hauv qis kub ib puag ncig. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, nws ntseeg tau tias yuav muaj cov thev naus laus zis zoo dua, thiab kev ua haujlwm ntawm qhov kub thiab txias pneumatic thaum muaj xwm ceev txiav tawm valve yuav siab dua thiab siab dua.
