ʻO ka hana ʻoihana ʻoihana ASME BS1873 hoʻolei ʻia i nā pahu kila honua e hoʻōki i ka valve China mea hoʻolako hale hana
He aha ka BS1873 globe valve?
BS1873 puni honua
ʻO ia kekahi o ka hoʻolālā kaulana loa o nā kīpē honua, no ka ʻōnaehana US a me API. ʻO ke anawaena o loko, nā mea, ke alo a ke alo, ka mānoanoa o ka paia, ka mahana wela, ua wehewehe ʻia e ASME B16.34.
kaBS1873 puni honuaHiki ke hoʻohana 'ia no ka throttling kumu as well.Many hoʻokahi-noho valve kino hoʻohana i ka hale paʻa a me ka retainer-style hana no ka malama ana i ka noho-poi, hāʻawi kiwikā plug alakai, a me ka hoʻolako 'ana i mea no ka hoʻokumu 'ana i kekahi mau hiʻona kahe.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 oBS1873 puni honua
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 hoʻololi lima ʻia ka huila lima me ka lima a i ʻole e ka mea hoʻokele, e hoʻomalu ʻia ka neʻe ʻana o ka disc (hoʻemi a hoʻokiʻekiʻe ʻia) ma o ke kumu valve.Ke noho ka puni honua kiwi ma luna o ke apo noho, ua pau loa ke kahe.
ʻO ka hiʻohiʻona nui o ka BS1873 globe valve
- 1) .Na mea hiki ke hoailona maikai
- 2) Ka mamao hele pōkole o ka disc(stroke) ma waena o nā kūlana hāmama a pani ʻia,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.
