Ukusetyenziswa ngokukhuselekileyo kwetanki yeDewar

I-Cryogenic Dewarsngokubanzi zineevalvu ezi-4, ezizezi, ivalve yokusetyenziswa kolwelo, ivalve yokusebenzisa igesi, ivalve yokuphuma, kunye nevalve yokunyusa. Kukwakho neegeyiji zoxinzelelo lwesigaba segesi kunye neegeyiji zenqanaba.IiDewarsazixhotyiswanga kuphela ngeevalvu zokhuseleko, kodwa kunye neediski eziqhumayo. Emva kokuba uxinzelelo lwegesi ebhotileni lugqithise ukunyanzeliswa kwe-valve yokhuseleko, ivalve yokhuseleko iya kukhupha ngokukhawuleza kwaye ikhuphe ngokuzenzekelayo uxinzelelo. Ukuba i-valve yokhuseleko iyasilela okanye i-cylinder yegesi ngengozi ibangela ukuba umaleko we-vacuum wonakaliswe, uxinzelelo kwibhotile lukhuphuka ngokukhawuleza ukuya kwinqanaba elithile, kwaye iidiski eziqhekezayo ezibekayo ziya kugqabhuka ngokuzenzekelayo, ngaloo ndlela zinciphisa ngokukhawuleza uxinzelelo kwibhotile kwi-atmospheric pressure.

Itanki ye-cryogenic Dewar igcina ioksijini yolwelo lwezonyango, eyandisa kakhulu umthamo wokugcina ioksijini. Umthamo wokugcina i-oksijini ye-cylinder ye-Dewar enomthamo we-175 L ilingana nomthamo wokugcina i-oksijini ye-28 yegesi ephezulu yoxinzelelo.

iisilinda ezinomthamo we-40 L, okunciphisa kakhulu uxinzelelo lokuthutha kunye nokunciphisa utyalo-mali lwenkunzi. Kukho iindlela ezi-2 zokusebenzisa itanki yeDewar:

(1) Ivalve yokusetyenziswa kwerhasi yeDewar, qhagamshela enye isiphelo sombhobho wentsimbi ephezulu kwivalve yokusetyenziswa kwegesi yeDewar kunye nesinye isiphelo kwi-busbar, vula kuqala ivalve, emva koko uvule ngokucothayo ivalve yokusetyenziswa kwegesi, ungasebenzisa, enkulu Uninzi lwezibhedlele zinokuhlangabezana neemfuno zegesi zisebenzisa ivalve yesigaba segesi kuphela.

(2) Ivalve yokusetyenziswa kolwelo lwetanki yeDewar, qhagamshela umbhobho apho ivalve yolwelo yeDewar ibekwe kwicarburetor enehose yentsimbi yoxinzelelo oluphezulu, ubungakanani bomatshini wokwenza igesi buqwalaselwe ngokwesixa segesi esetyenzisiweyo, kwaye umbhobho wentsimbi ongenamthungo usetyenziselwa ukuthutha irhasi. I-valve yoxinzelelo, i-valve yokukhusela, i-gauge ye-pressure gauge yokulawula ukhuseleko lwenkqubo yokubonelela ngegesi, ukwenzela ukuba kungekhona nje ukusebenzisa igesi ngokufanelekileyo kunye nokuzinza, kodwa nokuqinisekisa ukusetyenziswa okukhuselekileyo. Xa usebenzisa iDewar, nceda uqinisekise uqhagamshelo phambi kokuvula ivalve yokusetyenziswa kolwelo. Ukuba uxinzelelo lwegesi aluhambelani neemfuno zokusetyenziswa, unokuvula i-valve ye-booster. Uxinzelelo luya kuphakama kwaye luhlangabezane neemfuno zokusetyenziswa kwimizuzu embalwa.
