I-hydrogen iili mumaanzi ilijisi bubotu bumwi mukubamba akutola. Kweezyanisya a haayidirojeni, haayidirojeni iili mumaanzi (LH2) ilijisi bupati bupati alimwi iyanda nguzu zisyoonto kuti ibwezegwe. Nokuba boobo, haayidirojeni yeelede kuba -253°C kuti ibe maanzi, eezi zyaamba kuti nchintu chiyumu. Kupya kapati alimwi antenda zyakupya zipa kuti hydrogen iili mumaanzi ibe ntenda. nkaambo kaako, nzila zyakukwabilila ziyumu akusyomeka kupati nzintu zitayandiki pe aawo notubamba mavwili aabelesyegwa mumilimo yeelede.

Velan valve (Velan)
Kubelesya kwa hydrogen (LH2).
Kwalino, maanzi aa hydrogen alabelesyegwa akusolekwa kubelesyegwa muziindi zyaandeene. Mumulengalenga, ilakonzya kubelesegwa mbuli mafuta aakutonkela ma rocket mpawo ilakonzya kupanga mayuwe aakuzungaana mumigodi yamuwo. Kakugwasyilizyigwa "asayaansi mpati," hydrogen yamaanzi yaba chintu chipati muma superconducting systems, zibelesyo zifwambaanya tuniini, antoomwe azibelesyo zyakusanganya nyukiliya. Mbuli kulombozya kwabantu kwakusumpuka kutamani mbokuyaabukomena, hydrogen yamaanzi yakabelesegwa mbuli mafuta mumaloli amaato manji muminyaka misyoonto yainda. Mubukkale bwakubelesya buli atala aawa, bupati bwamavalvu bulibonya antangalala. Kubeleka kabotu akusyomeka kwamavwili nchintu chipati loko mukupa ma hydrogen (kupanga, kweenzya, kubamba akwaabila). Milimu iijatikizya maanzi aa hydrogen ilakatazya. Kajisi myaka iitandila makumi otatwe yaluzibo lwakubeleka aluzibo mumulimo wakupanga mavwili aabeleka obotu kusikila ku -272°C, Velan wakatola lubazu mumapulojekiti aasiyene-siyene aakupanga zintu zipya kwachiindi chilamfu, mpawo nchaantangalala kuti wakazunda buyumuyumu bwakubelesya maanzi aa hydrogen anguzu zyakwe.
Mapenzi muchiindi chakubamba
Kusinikizyigwa, kupya akuvwula kwa haayidirojeni zyoonse nzintu zipati zilangwa-langwa mukulanga-langa ntenda zyakupanga mavalvu. Kuti kube kuchita obotu kwa valve, bupange akusala zibelesyo zilaa mulimo mupati. Mavalvu abelesyegwa mukubelesya maanzi aa hydrogen alajana buyumuyumu bumbi, kubikkilizya azintu zibyaabi zikonzya kuchitika akaambo ka hydrogen kuzibulo. Aawo mpokutontola loko, zibelesyo zyamavalvu tazyeelede buyo kuliyumya kukulwanwa ama molecule aa haayidirojeni (zimwi nzila zyakunyonyooka zili mukubandikwa muziiyo), pesi zyeelede kubeleka kabotu kwachiindi chilamfu mubuumi bwazyo. Kweelana abukkale bwamazubaano bwakusumpuka kwabusongo, makwebo ajisi luzibo lusyoonto lwakubelesya zintu zitali zyabutale mukubelesya haayidirojeni. Notusala chakujala, nkuko kuyandika kubikkila maanu kukaambo aaka. Kujala kabotu akwalo nchintu chipati loko mumulimo wakubamba. Kuli kwiimpana kwakupya kwa 300°C aakati ka hydrogen yamaanzi akupya kwamukati (kupya kwamukati), eezi zipa kuti kube kusiyana kwakupya. Cibeela chimwi achimwi cha valve chiyooinda muzibeela zisiyene zyakuvwula akucheya. Ooku kutamvwana kulakonzya kuleta kuvwuuma kwamaanzi aayandika kapati. Kujala kwachisiko cha valve akwalo nchintu chibikkilwa maanu mukupanga. Kusanduka kuzwa kukutontola kuya kukupya kupa kuti kube kupya. Zibeela zipya zyabusena bwabboneti zilakonzya kupya, zikonzya kunyonganya mulimo wakujala ntambo akunyonganya kubeleka kwavalvu. Mukuyungizya, kupya kusyoonto kapati kwa -253°C chaamba kuti nzila mbotu yakukwabilila ilayandika kuchitila kuti vvalavu ikonzye kubamba hydrogen yamaanzi aawo kupya ooku kumwi kakucheya kusweekelwa akaambo kakubila. Kufumbwa buyo kuti kakuli kupya kunjililwa mu hydrogen, kuyoozwa akuzwa. Kutali nkuko luzutu, kuvwundauka kwa oxygen kulachitika aawo mpochityoka chikwabilizyo. Ikuti muya mubotu waswaangana a haayidirojeni naakuti zimwi zintu zipya, ntenda yamulilo ilatanta. Aboobo, notulanga ntenda yamulilo iikonzya kuchitwa amavalvu, mavalvu ayelede kuchitwa kajisi zintu zitakonzyi kupwasuka, antoomwe azintu zitakonzyi kupya, zibelesyo antambo, zyoonse kazijisi zyilengwa ziyumu. Eezi zipa kuti vvalavu ibeleke obotu kuti kwaba mulilo. Kuyungizya muya akwalo ntenda iikonzya kupa kuti mavalvu atabeleki pe. Kuti haayidirojeni yamaanzi yajalilidwe mumulyango wamubili wavalvu mpawo kupya akuzwa kwa haayidirojeni yamaanzi kwachitika achiindi chomwe, kuyoopa kuti kusinikizyigwa kuyungizigwe. Kuti kakuli kwiimpana kupati kwakusinikizyigwa, kuvwundauka (kuvwundauka)/muzuzumo kulachitika. Eezyi zintu zilakonzya kuleta mamanino aabuumi bwa valve kakutanainda chiindi, mpawo akusweekelwa kupati akaambo kakulezya kwanzila. Nikuba kuti bukkale bwakubeleka buli buti, ikuti twaambo tuli atala aawa twabikkilwa maanu mpawo nzila zyakukazya zyatolwa munzila yakubamba, zilakonzya kupa kuti vvalavu ibeleke kabotu alimwi isyomeka. Mukuyungizya, kuli buyumuyumu bwakupanga bujatikizya makani aabusena, mbuli kuvwundauka kwamaanzi. Hydrogen ililibedelede: tuniini, tutakwe mubala, tutakwe kununkilila, alimwi tulakonzya kupwasuka. Eezyi zitondeezyo zipa kuti kube kuyandikana kwakuti kutabi kuvwundauka.
Ku North Las Vegas West Coast Hydrogen Liquefaction station,
Bainjiniya ba Wieland Valve bali mukupa milimu yabusongo
Nzila zyakumanizya mapenzi
Nikuba kuti mulimo uli buti amusyobo, mavwili aabelesyegwa muma hydrogen woonse ayelede kuzuzikizya zimwi ziyandikana. Eezyi ziyandikana zibikkilizya: zintu zyakubelesya muchibeela chakuyaka zyeelede kusinizya kuti chiyaka chikwabilidwe muchiindi chakupya loko; Zintu zyoonse zyeelede kuba azintu zikwabilila mulilo. nkaambo kaako, zintu zyakujala akupakila mavalvu aa hydrogen ayelede kuzuzikizya ziyandikana zyaambwa atala aawa. Butale butakwe tombe bwa Austenitic nchintu chibotu loko chakupanga mavalvu aa hydrogen. Chili anguzu zyakuuma zibotu, kusweekelwa kupya kusyoonto, mpawo chilakonzya kuliyumya muchiindi chilamfu. Kuli zimwi zintu zikonzya kubelesegwa mubukkale bwa hydrogen, pesi zilakonzya kubelesegwa mubukkale bumwi. Mukuyungizya kukusala zibelesyo, zimwi zintu zyakupanga tazyeelede kulekelezyegwa pe, mbuli kutandabika chisiko cha valve akubelesya muya wakukwabilila chikwabilizyo kuzwa kukupya kapati. Mukuyungizya, kuyungizigwa kwachisiko cha valve kulakonzya kubikwa achikwabilizyo chakukwabilila kuchitila kuti kutabi kuvwuuma. Kubamba mavalvu kweendelanya abukkale bumwi bwakubelesya kulagwasya kupa nzila zibotu zyakumanizya mapenzi aaindene-indene. Vellan ulapa mavalvu aabutterfly munzila zyobile zisiyene: mavalvu aabutterfly aajisi zibeela zyobile alimwi aatatu aatali kabotu. Mizeezo yoonse yobile ilakonzya kweenda mumabazu obile. Kwiinda mukubamba chiimo chadisiki anzila yakuzinguluka, kujala kujatikizyidwe kulakonzya kuchitwa. Kunyina mpako mumubili wavalvu oomo mutakwe chintu chisyaala. Muchiimo cha Velan double eccentric butterfly valve, ibelesya nzila ya disc eccentric rotation design, antoomwe anzila yakujala ya VELFLEX, kuchitila kuti kube kujala kabotu kwa valve. Ooku kubamba kwakazumizyigwa kulakonzya kuliyumya nokuba kuchincha kupati kwakupya muvalvu. I TORQSEAL triple eccentric disc alimwi ilijisi nzila yakuzyunguluka yakapangwa munzila iilibedelede iigwasya kusinizya kuti busena bwakujala disiki bujata buyo chibbula aawo nobusika aawo mpobujala vvalavu mpawo tabukwe pe. Aboobo, nguzu zyakujala zya vvalavu zilakonzya kweenzya disiki kuti zikkale kabotu, mpawo zipa kuti disiki ibe achuuno chizulide muchimo cha valve chijalidwe, kumwi kachita kuti disiki ijatane abwaanda boonse bwakujala chibbula. Kutobelezya kwachuuno cha valve kupa kuti mubili wa valve a disiki zibe amulimu wakulibambila, aboobo kutabilila kujatwa kwa disiki muchiindi chakucinca kwakupya. Ibbokesi lyamavwili lyabutale butakwe tombe lilakonzya kubeleka ziindi zyiingi mpawo lilabeleka kabotu aawo nokwatontola loko. Bupange bwa VELFLEX bupa kuti vvalavu ibelesegwe a intaneti chakufwambaana mpawo kakunyina kukatazya. Twalumba akaambo kachibaka chili kumbali, chibbula a disiki zilakonzya kulanga-langwa naakuti kubambululwa, kakunyina kuyandika kugwisya ntalisyo naakuti zibelesyo zilibedelede.
