Cryogenic Globe Valve Hoʻonui ʻia ka Bonnet no -196 ℃

1. Hoʻolālā ʻia ka pāpale valve e hoʻolōʻihi i ka hoʻolālā bonnet, hiki ke hoʻokaʻawale i ka mana o ka media haʻahaʻa haʻahaʻa ma ka paʻi ʻana, e pale i ka hana o ka sila uhi, a me ka wehe ʻana a me ka hoʻopaʻa ʻana i ka valve me ka maʻalahi;
2. Hoʻohana ka mea hoʻopihapiha i ka graphite maʻalahi a i ʻole 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 ʻo Gasket i ka ʻili ʻili kila polytetrafluoroethylene a i ʻole ka graphite maʻalahi wili;
4. i ka wā e pani ʻia ai ka valve, i mea e pale aku ai i ka piʻi ʻana o ka haʻahaʻa haʻahaʻa i loko o ke keʻena valve ma muli o ka wela, ka hopena o ka piʻi ʻana o ke kaomi maʻamau, hāʻawi ʻia ke ʻano hoʻoluhi kaomi ma ka ʻaoʻao kiʻekiʻe o ka puka a i ʻole ke kino valve;
5. ka sila ili o ka kiwikā surfacing cobalt-ma muli cemented carbide, tungsten carbide ma haʻahaʻa wela deformation mea uuku, aahu ke kū'ē, hiki ke malama maikai sealing hana.
No ka mea, ʻo ka hoʻopuka ʻana o ka wai haʻahaʻa haʻahaʻa haʻahaʻa e like me ka ethylene, wai oxygen, wai hydrogen, liquefied natural gas, liquefied petroleum a me nā huahana ʻē aʻe ʻaʻole hiki ke puhi a pahū wale nō, akā ke gasification hoʻi i ka wā e hoʻomehana ai, a hoʻonui ka leo i nā haneli mau manawa. hoʻoheheʻe ʻia. He mea koʻikoʻi ka mea o ka valve haʻahaʻa haʻahaʻa, a ʻaʻole kūpono ʻia ka mea, e hoʻoheheʻe ai i waho a i ʻole leakage o loko o ka pūpū a me ka ʻili o ka sila; ʻAʻole hiki i nā ʻāpana mechanical piha, ikaika a me ke kila o nā ʻāpana ke hoʻokō i nā koi o ka hoʻohana ʻana a i ʻole ka haki; ʻO ka hopena i ka liquefied natural gas medium leakage ma muli o ka pahū. No laila, i ke kaʻina hana o ka hoʻomohala ʻana, ka hoʻolālā ʻana a me ka hoʻomohala ʻana i nā valve haʻahaʻa haʻahaʻa, ʻo ka mālama ʻana i nā mea ke kumu nui.
