Ukwethulwa kwe-valve yebhola ye-cryogenic

Isimiso sokusebenza

I-valve yebhola yokushisa ephansi ngokuvamile isetshenziswa esimweni lapho izinga lokushisa eliphakathi lingaphansi -40 ℃, futhi i-valve flap ivuleka ngokuzenzakalelayo futhi ivalwe kuye ngokugeleza kwe-medium ngokwayo, ukuze kuvinjwe okuphakathi ukuthi kungabuyeli emuva.

Izici

1. Isakhiwo sokuvula imbobo yokusiza ingcindezi ku-valve core yamukelwa;
2. I-gasket yenziwe ngezinto zokugcwalisa i-ceramic ngokuvaleka okuzinzile;
3. Umzimba we-valve ulula futhi uncane ngosayizi.Ukuze kuncishiswe ukulahlekelwa ukushisa komzimba we-valve, ikakhulukazi ukuqinisekisa ukusetshenziswa kwe-valve ngaphansi kokushisa kwe-ultra-low, umzimba we-valve uklanyelwe ngokukhethekile ukuba ube nesisindo esincane futhi usayizi omncane;
4. I-valve ye-eksisi ende ine-valve okugeleza kuyo uketshezi olunezinga lokushisa eliphansi.Yamukela uhlobo lwesiqu se-valve ende, engagwema umphumela wokushisa kwangaphandle futhi igcine indlala ekushiseni okuvamile ukuvimbela ukusebenza kophawu lwekhava ekuncishisweni.Lobu bude ubude obuphelele obutholwa ngokubala nokuhlola.

Izinzuzo zohlelo lokusebenza

1. Ukumelana noketshezi kuncane.I-valve yebhola inokumelana noketshezi okuncane kakhulu phakathi kwawo wonke ama-valve.Ngisho ne-diameter ye-diameter encishisiwe i-valve yebhola inokumelana noketshezi oluncane;
2. Iswishi iyashesha futhi ifanelekile.Uma nje isiqu se-valve sijikeleza ngo-90 °, i-valve yebhola iqeda ukuvuleka okugcwele noma isenzo sokuvala esigcwele, futhi kulula ukubona ukuvuleka nokuvala ngokushesha;
3. Ukusebenza kahle kokubekwa uphawu.Indandatho yokuvala yesihlalo se-valve yebhola ngokuvamile yenziwe ngezinto ezinwebekayo ezifana ne-polytetrafluoroethylene, okulula ukuqinisekisa ukubekwa uphawu, futhi amandla okuvalwa kwe-valve yebhola akhuphuka ngokunyuka kwengcindezi ephakathi;
4. I-stem seal ithembekile.Lapho i-valve yebhola ivulwa futhi ivaliwe, isiqu se-valve sijikeleza kuphela, ngakho-ke uphawu lokupakisha lwe-valve akulula lonakaliswa, futhi amandla okuvala uphawu lwe-reverse ye-valve stem ayanda ngokunyuka kokucindezela okuphakathi. ;
5. Ukuvulwa nokuvalwa kwe-valve yebhola kushintsha kuphela i-90 °, ngakho-ke kulula ukubona ukulawula okuzenzakalelayo nokulawula okukude.I-valve yebhola ingahlonyiswa ngezinto ezisebenza ngomoya, izinto zikagesi, izinto ezisebenza ngogesi, izinto zokuxhumanisa uketshezi lwegesi noma izinto zokuxhumanisa i-electro-hydraulic;
6. Ishaneli ye-valve yebhola iyisicaba futhi ibushelelezi, futhi akulula ukufaka i-medium, futhi ipayipi lingadlula ebholeni.

Isondlo

1. Hlola ukuthi likhona yini iqhwa emzimbeni wevalvu, uma kunjalo, sicela ususe noma yiliphi iqhwa emzimbeni wevalvu, bese usebenzisa ivalvu;
2. Sebenzisa isibhamu se-grease manual noma se-pneumatic ukugcwalisa isisombululo sokuhlanza i-valve, futhi usebenzise i-valve ngemva kwemizuzu engu-10-20 ukukhipha indle ku-nozzle yokukhipha i-valve;
3. Bheka ukupakishwa kwesiqu se-valve, i-flange emaphakathi nezinye izingxenye ukuthi azivuzi yini;
4. Uma kukhona ukuvuza esiqwini se-valve, sicela uhlole ukuthi i-valve inesakhiwo somjovo we-valve stem, uma kunjalo, faka kancane kancane i-valve yokuvala igrisi bese uyeka ukugcwalisa;
5. Ukwelashwa kwangaphakathi kokuvuza kwe-valve yebhola ephansi yokushisa kuhlanziwe, futhi isisombululo esiyinhloko siwumsebenzi.Ukwengeza amafutha okufaka uphawu kuyindlela eyisizayo;
6. Uma i-valve ivaliwe ngokuphelele, ukuhlolwa kokuvuza kwangaphakathi kanye nokwelashwa kwe-valve yebhola ephansi yokushisa kufanele kwenziwe ngangokunokwenzeka;
Ukusebenza kwe-valve ebandayo kufanele kuvule futhi kuvalwe ngokuphelele ngangokunokwenzeka, futhi i-valve engakwazi ukuvulwa nokuvala kufanele ihanjiswe ngangokunokwenzeka.
