ASME Globe Valve
He aha ka ASME Globe Valve?
ʻO nā kiwi poʻo poʻipoʻi he mau pahu pani pani laina laina i hoʻohana ʻia e hoʻomaka, hoʻōki a hoʻoponopono paha i ke kahe me ka hoʻohana ʻana i kahi lālā pani i kapa ʻia he diski.Aia ka noho o ka valve puni honua i waenakonu a ua like me ka paipu, a ua pani ʻia ka wehe ʻana o ka noho me ka disc a i ʻole plug. Hiki ke pani piha i ke ala kahe a hiki ke hoʻoneʻe ʻia ka pahu pahu honua.Hoʻololi like ka wehe ʻana o ka noho me ka huakaʻi o ka disc i kūpono no nā hana e pili ana i ka hoʻoponopono kahe.ʻOi aku ka maikaʻi a hoʻohana nui ʻia nā valve Globe e hoʻomalu a hoʻōki i ke kahe ʻana o ka wai a i ʻole ke kinoea ma o ka paipu no ka throttling a me ka hoʻokele ʻana i ka kahe wai a hoʻohana mau ʻia i nā paipu liʻiliʻi.
ASME Globe valveʻO ia kekahi o ka hoʻolālā kaulana loa o ka honua valves, no ka US a me API system.the inside diameter, material, the face to face, wall thickness, pressure temperature, ua wehewehe ʻia e ASME B16.34.
Eia kekahi, ma muli o ka hoʻolālā ʻana o ka noho a me ka disc, ka ukana o ka nohoʻO nā kiwi honua ASMEhiki ke hoʻomalu maikaʻi ʻia e kahi ʻōpala wili.ʻO ka hiki ke hoʻopaʻa ʻia o kaASME puni honua valvehe kiekie loa.Hiki ke hoʻohana 'ia no ka on-off duty.Ma muli o ka pōkole huakaʻi hele o ka diski ma waena o ka hamama a me ka paniia kulana,ʻO nā kiwi honua ASMEkūpono inā pono e wehe a pani pinepine ʻia ka valve.No laila, hiki ke hoʻohana ʻia nā kīwaha honua no ka nui o nā hana.
kaASME Globe valvesHiki ke hoʻohana ʻia no nā kumu throttling like.Many hoʻokahi-noho valve kino hoʻohana i ka hale paʻa a i ʻole ke ʻano o ka hale paʻa no ka mālama ʻana i ke apo noho, hāʻawi i ke alakaʻi ʻana i ka pahu valve, a hāʻawi i kahi ala no ka hoʻokumu ʻana i nā hiʻohiʻona kahe o ka valve.hiki ke hoʻololi maʻalahi ʻia e ka hoʻololi ʻana i nā ʻāpana ʻoki e hoʻololi i ke ʻano kahe a hāʻawi i ka mana hoʻemikahe ʻana, ka leo attenuation, a i ʻole ka hōʻemi a i ʻole ka hoʻopau ʻana i ka cavitation.
ʻO ASME Globe Valve Body Patterns, aia ʻekolu mau hiʻohiʻona kino mua a i ʻole nā mea hoʻolālā no nā kīwaha Globe, ʻo ia hoʻi:
- 1). Kūlana Kūlana (ʻike pū ʻia ʻo Tee Pattern a i ʻole T - Pattern a i ʻole Z - Pattern)
- 2).
- 3).Oblique Pattern (ʻike pū ʻia ʻo Wye Pattern a i ʻole Y - Pattern)
Ku'ina Hana oASME Globe Valve
Aia ka valve honua i kahi diski ho'one'e a me kahi noho apo pa'a i loko o ke kino spherical.Aia ka noho o ka valve puni honua i waenakonu a ua like me ka paipu, a ua pani ʻia ka puka o ka noho me ka diski.ke hoʻohuli lima lima ʻia ka huila lima a i ʻole e kekahi mea hoʻokele, e hoʻomalu ʻia ka neʻe ʻana o ka diski (hoʻemi a hoʻokiʻekiʻe ʻia paha) ma o ke kumu valve.Ke kau ka pōpoe kīpē diski ma luna o ke apo noho, ua pau loa ke kahe.
ʻO ka hiʻohiʻona nui o ka valve ASME Globe
- 1) .Na mea hiki ke hoailona maikai
- 2) .Short huakaʻi mamao o ka disc(stroke) ma waena o ka hamama a pani pani,ʻO nā kiwi honua ASMEkūpono inā pono e wehe a pani pinepine ʻia ka valve;
- 3).Hiki ke hoʻohana ʻia ka valve honua ASME ma ke ʻano he pahu hoʻomaha ma ka hoʻololi iki ʻana i ka hoʻolālā.
- 4).Teia ka laulā o nā mana e like me ka loaʻa ʻana ma ke kāʻei, Wye, a me nā ʻano kino kihi.
- 5).ʻO ka mīkini maʻalahi a me ka hoʻoulu hou ʻana o nā noho, no nā kumu like ʻole.
- 6).Maikaʻi i ka hiki ke throttling maikaʻi, ma ka hoʻololi ʻana i ke ʻano o ka noho a me ka disc.
- 7).BLoaʻa ka sila ellows ma ke noi.
