Li-valve tsa cryogenic li sebelisoa haholo masimong a manyolo, LNG le indasteri ea petrochemical. Ntle le naetrojene ea mokelikeli le likhase tse ling tsa inert tsa mokelikeli, boholo ba mecha ea litaba e laoloang ha e chese feela ebile ea phatloha, empa hape le gasification e etsahala ha e futhumala kapa e benya. , Ho fella ka ho atolosoa ka potlako ha molumo, ho bonolo ho baka ho lutla le ho phatloha. Indastering, li-valve tse sebelisoang mocheso o bohareng o ka tlase ho -40 ℃ hangata li bitsoa li-valve tsa cryogenic, 'me li-valve tse sebelisoang mocheso o bohareng o ka tlase ho -101 ℃ li bitsoa li-valve tsa mocheso o tlase haholo.
Khetho ea lisebelisoa bakeng sa li-valve tsa cryogenic:
Thepa ea mochini ea tšepe ka mocheso o tlase o fapane le oa mocheso oa kamore. Ho phaella ho matla, matla a ts'usumetso ea mocheso o tlaase ke index ea bohlokoa haholo bakeng sa tšepe e tlaase ea mocheso. Boemo bo tlase ba mocheso bo matla ba thepa bo amana le mocheso oa phetoho ea brittle ea thepa. Ha mocheso oa brittle transition o le tlase oa thepa, ho tla ba betere ho ba le tšusumetso e tlase ea mocheso oa thepa. Lisebelisoa tsa tšepe tse nang le li-cubic lattice tse bohareng ba 'mele tse kang tšepe ea carbon li na le brittleness e batang ea mocheso o tlase, athe lisebelisoa tsa tšepe tse nang le li-cubic lattice tse bohareng ba sefahleho tse kang austenitic stainless steel ha e le hantle ha li na tšusumetso ho matla a tšusumetso ea mocheso o tlase.
'Mele oa li-valve tsa mocheso o tlase, bonnet le likarolo tse ling tse hananang le khatello hangata li entsoe ka thepa e nang le matla a tlase a mocheso le boima. Ka nako e ts'oanang, lintlha tse kang weldability, machinability, botsitso le moruo le tsona li tlameha ho nkoa.
Ha ho etsoa moralo, maemo a mararo a mocheso o tlase oa -46 ℃, -101 ℃ le -196 ℃ a sebelisoa hangata. Mocheso o tlase oa carbon steel hangata o sebelisetsoa -46 ℃ mocheso o tlase, 'me 300 series austenitic stainless steel hangata e sebelisetsoa -101 ℃ le -196 ℃ ea mocheso o tlase. Tšepe ena e sa hloekang e na le matla a itekanetseng, ho tiea ho hotle le ho sebetsa hantle.
