Liquid hydrogen nih chiahnak le phorhnak ah tthatnak cheukhat a ngei. Hydrogen he tahchunh ahcun, ti hydrogen (LH2) cu a rit deuh i chiahnak caah a niam deuhmi hneknak a herh. Sihmanhsehlaw, hydrogen cu ti bantuk si awkah -253°C a si a hau, cucu a har ngai tinak a si. A lin tukmi le mei kangh khawhnak ttihnung nih ti hydrogen cu tihnung thilri ah a ser. Hi ruang ah, a fekmi himnak phunglam le zumhawktlak sinak sang cu aa pehtlaimi hmannak caah valve suai tikah a ttha lomi a herhmi an si.

Velan valve (Velan)
Liquid hydrogen (LH2) hmannak.
A tu ahcun, ti bantuk hydrogen cu hman a si i caan sunglawi phunphun ah hman an i zuam. Vanlawng ah, rocket thlahnak meihol ah hman khawh a si i transonic thli laknak ah shock wave zong a chuahter khawh. "Science nganpi" nih a dirpi caah, ti hydrogen cu superconducting system, particle accelerator, le nuclear fusion thilri ah a biapi tukmi thilri ah a cang. Mipi nih a hmunmi thanchonak an duhnak a karh chin lengmang caah, naite kum hna ah hin liquid hydrogen cu mawtaw le tilawng tam deuh nih meihol ah an hman. A cunglei hmannak thil sining ah, valve a biapitnak cu a fiang tuk. Valve hna i a himmi le zumhawktlakmi riantuannak cu ti hydrogen phorhnak ecosystem (chuahnak, phorhnak, chiahnak le phawtzamhnak) ah a biapi tukmi a si. Liquid hydrogen he aa pehtlaimi riantuannak cu a har ngai. -272°C tiang a ttha ngaimi valve sernak ah kum 30 leng hmuhtonnak le thiamnak he, Velan cu caan saupi chung thilthar sernak project phunphun ah aa tel cang, cun a thazaang in liquid hydrogen service thiamnak lei zuamcawhnak hna kha a tei cang ti cu a fiang ko.
Design tuah lio ah harnak a ummi
Valve suaisamnak ttihnung zohfelnak ah zohfelmi thil biapi vialte cu hneknak, lumternak le hydrogen tlawmtam an si. Valve riantuan ning tthatternak caah, suaisamnak le thilri thimnak nih biakhiahnak a tuah. Liquid hydrogen hmannak ah hmanmi valve pawl nih thir cungah hydrogen nih a chuahpimi thil ttha lo hna telh in harnak dang an tong. A niam tukmi lumnak ah, valve thilri hna nih hydrogen molecule pawl tukdohnak lawng si loin (a pehtlaimi rawhnak lam cheukhat cu sianginn ah an i al rih), asinain an nunchung caan saupi chung a ttha tein rian a ttuan a hau. A tu lio thiamnak lei tthanchonak he pehtlai in, hi riantuannak nih hin hydrogen hmannak ah thir a si lomi thilri hman khawhnak kong ah theihhngalhnak tlawmte lawng a ngei. Sealing thilri thim tikah, hi thil hi ruah chih a herh. A ttha mi kharnak zong hi suaisamnak riantuan ning tahfung biapi pakhat a si. Liquid hydrogen le pawngkam lumnak (innchung lumnak) karlak ah 300°C hrawng lumnak aa dannak a um, cu nih cun lumnak aa dannak a chuahter. Valve chung i a ummi thilri pakhat cio nih lumnak karhternak le tlawmternak degree aa dangmi an tuar lai. Hi aa dannak nih hin a biapi tukmi kharnak cunglei hna ah tihnung a chuahter khawh. Valve stem i a kharnak fek zong hi suaisamnak ah a biapi bikmi a si. Khuasik in a linmi ah thlennak nih lumnak a chuahter. Bonnet kuang chung i a linmi hmun pawl cu a lum kho, cu nih cun thinghnah kharnak riantuan ning a hrawh khawh i valve riantuan ning a hnorsuan khawh. Cun, a niam tukmi -253°C nih a chim duhmi cu a lum tukmi nih a chuahtermi sunghnak a zorter lio ah valve nih hi lumnak ah liquid hydrogen a tlaih khawh nakhnga a tha bikmi lumternak thiamnak a herh tinak a si. Liquid hydrogen ah lumnak a thlen chung paoh cu, a lum lai i a luang lai. Cu lawng si loin, oxygen tlawmternak cu insulation a rawhnak hmun ah a cang. Oxygen cu hydrogen asiloah a dang meikanghnak thilri he an i tong tikah, meikanghnak ttihnung a karh. Cucaah, valve nih a ton khawhmi meikanghnak ttihnung kha ruah tikah, valve pawl cu a puak kho lomi thilri pawl ruahnak he suai a hau, cun meikangh a doh khomi actuators, thilri le cable hna zong, an dihlak in a fekmi hnatlaknak he an ser a hau. Mah nih hin meikangh a chuah tikah valve cu ttha tein rian a ttuan khawhnak hnga a bawmh. A karhmi hneknak zong hi valve pawl riantuan khawh lonak a chuahter khomi ttihnung a si. Ti hydrogen cu valve pum chung ah a tla i lumnak thlennak le ti hydrogen hnimhnak cu caankhatte ah a cang ahcun, cu nih cun hneknak a karhter lai. Pressure aa dannak nganpi a um ahcun, cavitation (cavitation)/aw a chuak. Hi thil cangmi hna nih hin valve riantuannak nunnak a caan hlan ah a donghter khawh, cun thil kalning tlamtlin lonak ruangah sunghnak nganpi hmanh a tuar khawh. A bik in riantuannak dirhmun zeirel loin, a cunglei thil hna kha tling tein ruah khawh a si i aa pehtlaimi dohnak hna kha suaisamnak kalning ah tuah khawh a si ahcun, valve a himmi le zumhawktlakmi riantuannak kha a hngalhter khawh. Cun, pawngkam kong he aa pehtlaimi suaisam harnak zong a um, cu hna cu a zammi ti a luannak tibantuk an si. Hydrogen cu aa dang: molecule hmete, rong a ngei lomi, rim a ngei lomi le a puak khomi. Hi sining hna nih hin zero leakage a herh taktakmi kha a khiah.
North Las Vegas West Coast Hydrogen Liquefaction station ah,
Wieland Valve engineer pawl nih thiamnak lei riantuannak an pek hna
Valve a phichuak
A bik in riantuannak le phun zei a si hmanh ah, liquid hydrogen hmannak vialte caah valve pawl nih a tlangpi in herhmi cheukhat an tlinh a hau. Hi a herhmi hna ah aa telmi hna cu: saknak tthen thilri nih saknak tthatnak kha a niam tukmi lumnak ah kilven a si lai ti kha a hngalhter a hau; Thilri vialte nih mei kanghnak himnak thilri an ngeih dih a hau. Cu ruang lila ah cun, ti hydrogen valve pawl kharnak thilri le chiahnak zong nih a cunglei langhtermi a hrampi herhmi hna kha a tlinh ve a hau. Austenitic stainless steel cu ti hydrogen valve caah thilri tha taktak a si. A ttha tukmi tuknak thazaang a ngei, lumnak tlawmte lawng a sungh, cun lumnak thlennak nganpi a tuar khawh. Liquid hydrogen dirhmun caah aa tlakmi thilri dang zong an um, asinain a hleiin tuahsernak dirhmun ah rikhiahmi an si. Thilri thimnak lengah, suaisam ningcang cheukhat kha philh awk a si lo, cu hna cu valve stem sauhter le a niam tukmi lumnak in sealing packing huhphenh awkah thli column hman tibantuk an si. Cun, valve stem a kauhnak cu ti a luan lonak ding caah insulation ring he chiah khawh a si. A hleiin hmannak thil sining ningin valve suaisamnak nih thiamnak lei harnak phunphun caah aa tlakmi a phichuak pek awkah a bawmh. Vellan nih butterfly valve pawl cu design phun hnih in a pek hna: double eccentric le triple eccentric thir seat butterfly valves. Design pahnih nih hin lam pahnih in a luang khomi an ngei. Disc muisam le aa mernak lamthluan suaisamnak thawngin, a fekmi kharnak kha hmuh khawh a si. Valve pum chung ah a tangmi thilri a um lonak hmun ah khur a um lo. Velan double eccentric butterfly valve kongah, a ttha tukmi valve kharnak riantuannak hmuh khawhnak ding caah, a dang tein a ummi VELFLEX kharnak system he fonh in, disc eccentric rotation design kha a hman. Hi patent tuahmi suaisam nih hin valve chung i lumnak thlennak nganpi hmanh a tei khawh. TORQSEAL triple eccentric disc zong nih a hleiin sermi aa mernak lam a ngei i mah nih cun disc kharnak cunglei nih kharmi valve dirhmun a phak tikah tthutnak lawng a tawngh i a hliah lo nakhnga a bawmh. Cucaah, valve kharnak thazaang nih disc kha aa tlakmi ṭhutnak hmuh khawhnak dingah a hruai khawh, cun kharmi valve dirhmun ah a za tawk in wedge effect a chuahter khawh, cu lioah disc cu ṭhutnak kharnak cunglei dihlak he aa tluk tein aa pehtlaih khawh. Valve tthutnak zulhphung nih valve pum le disc kha “mah tein aa remh khawhnak” riantuannak a ngeihter, cucaah lum le kih aa thleng tikah disc tlaih kha a hrial. A fekmi thir thir valve shaft cu riantuannak caan sau a ngei kho i a niam tukmi lumnak ah tluang tein a rian a ttuan. VELFLEX aa dangmi suaisam nih valve cu online in rang tein le fawi tein zohkhenh khawhnak a tuah. A kam inn ruangah, tthutdan le disc cu direct in zohfel khawh asiloah remh khawh a si, actuator asiloah thilri ttha hna kha phoih a hau lo.
