-196 ℃ belofo ea serurubele sa Cryogenic Bi-directional

Ka sehlahisoa sa NSEN fetisa tlhahlobo ea bopaki ho latela maemo a BS 6364:1984 ke TUV.NSEN e ntse e tsoela pele ho tlisa sehlopha sa "bi-directional sealing" cryogenic butterfly valve.

Li-valve tsa Cryogenic li sebelisoa haholo indastering ea LNG. Ha batho ba ela hloko haholoanyane litaba tsa tikoloho, LNG, mofuta ona oa matla a hloekileng o ratoa.

Kaha mocheso oa LNG tlas'a khatello e tloaelehileng ke -162 ℃, 'me o na le litšobotsi tsa ho chesa le ho phatloha, valve ea mocheso oa cryogenic ha e finyelle feela litlhoko tsa mocheso o tlaase oa mocheso, empa hape o hloka ho nahana ka moralo oa tšireletso ea mollo.Ke hantle ka lebaka la litlhoko tsena hore polokeho le ts'epo ea li-valve tsa cryogenic li tla ba tse phahameng ho feta li-valve tse tloaelehileng.

Habohlokoa le ho feta, 'mele oa li-valve, poleiti ea serurubele, karolo e atolositsoeng le likarolo tse ka hare li tlameha ho sebetsoa ka mokhoa oa cryogenic pele o qeta ho felisa tšusumetso ea phetoho ea mohato.Ho seng joalo, phetoho ea karolo ea martensite e tla etsahala ka mocheso o tlase, e leng se bakang deformation ea valve, e leng se etsang hore valve e lutle.

Mofuta oa khokahano bakeng sa thomello ena ke flange le wafer, 'me thepa ea' mele oa valve le disc ke CF8M.Thepa e tiisang e ntse e le moralo oa selikalikoe o tiileng oa tšepe o tiileng, o nang le tiiso e tlase ea kutu.

Haeba u na le tšepo ea ho ithuta ho eketsehileng kapa ho fumana tharollo bakeng sa morero oa hau, amohela ho ikopanya le rona.
