ʻO ka Cryogenic Globe Valve Extended Bonnet no -196 ℃

1. Ua hoʻolālā ʻia ka pāpale kiwikā e hoʻolōʻihi i ka hoʻolālā pāpale, hiki ke hoʻokaʻawale i ka mana o nā pāpaho haʻahaʻa haʻahaʻa ma ka hoʻopili ʻana, pale i ka hana o ke sila uhi, a hana pū i ka pani ʻana a me ka wehe ʻana o ka kiwikā;
2. hoʻohana ka mea hoʻopihapiha i ka graphite palupalu a i ʻole ka polytetrafluoroethylene i hui pū ʻia, me ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi;
3. Hoʻohana ka valve haʻahaʻa haʻahaʻa i ke ʻano o ka wehe ʻana i kahi lua decompression ma ke kumu valve. Hoʻohana ka Gasket i ka ʻili kila kila kila polytetrafluoroethylene a i ʻole ke ʻano wili graphite maʻalahi;
4. ke pani ʻia ka valve, i mea e pale ai i ka piʻi ʻana o ka mahana o ka mea haʻahaʻa i loko o ke keʻena valve ma muli o ka mahana, e hopena ana i ka piʻi ʻana o ke kaomi maʻamau, ua hoʻolako ʻia kahi ʻano hoʻomaha kaomi ma ka ʻaoʻao kiʻekiʻe o ka puka pā a i ʻole ke kino valve;
5. ʻO ka ʻili sila o ka ʻili valve me ka cobalt-based cemented carbide, ʻo ka tungsten carbide i ka haʻahaʻa haʻahaʻa e liʻiliʻi ka deformation, ʻaʻahu ke kū'ē, hiki ke mālama i ka hana sila maikaʻi.
No ka mea, ʻo ka hopena o nā mea hoʻoheheʻe wai haʻahaʻa e like me ka ethylene, ka oxygen wai, ka hydrogen wai, ke kinoea kūlohelohe liquefied, ka petroleum liquefied a me nā huahana ʻē aʻe, ʻaʻole wale ia he mea lapalapa a pahū, akā, he gasification hoʻi i ka wā e hoʻomehana ai, a hoʻonui ʻia ka nui i nā haneli he nui i ka wā e gasification ai. He mea nui loa ka mea o ka valve haʻahaʻa, a ʻaʻole kūpono ka mea, kahi e hoʻoulu ai i ka leaka waho a i ʻole ka leaka kūloko o ka pūpū a me ka ʻili sila; ʻAʻole hiki i nā waiwai mechanical piha, ka ikaika a me ke kila o nā ʻāpana ke hoʻokō i nā koi o ka hoʻohana a i ʻole ka haki ʻana; ʻO ka hopena i ka leaka waena o ke kinoea kūlohelohe liquefied i hoʻokumu ʻia e ka pahū. No laila, i ke kaʻina hana o ka hoʻomohala ʻana, ka hoʻolālā ʻana a me ka hoʻomohala ʻana i nā valves haʻahaʻa, ʻo ka mālama ʻana i nā mea ke kumu nui.
