ʻOkoʻa ma waena o ka Forged Steel Valve a me ka Cast Steel Valve

I. Ke Kaʻina Hana Hana

Hana ʻia ka Valve Check Steel Forged ma Kina:

Hana ʻia ma o ke kaʻina hana forging, hoʻomehana ʻia ka billet kila a hoʻopili ʻia ke kaomi (e like me ke kuʻi ʻana, extrusion) e hana iā ia, a laila hana ʻia ka hana mechanical.

ʻO ke kaʻina hana forging e hoʻomaʻemaʻe i nā ʻano metala a paʻa ka hale, me ka ʻole o nā kīnā e like me nā pores a me nā inclusions slag.

Kiwikā kila i hoʻolei ʻia:

Hana ʻia ma o ke kaʻina hana hoʻolei, ninini ʻia ke kila i hoʻoheheʻe ʻia i loko o kahi ʻōmole e hoʻomaʻalili a hana ʻia, a laila hana ʻia.

Hiki i ke kaʻina hana hoʻolei ke hana i nā pilikia e like me nā pores, nā lua shrinkage a i ʻole ke ʻano kūlike ʻole, pono e hoʻomaikaʻi ʻia ma o ka hana ʻana ma hope.

II. Nā Waiwai Mea

Kiwikā kila i hana ʻia:

Ikaika kiʻekiʻe: Hoʻopau ka hana ʻana i nā kīnā kūloko, a ʻoi aku ka maikaʻi o ka ikaika mechanical (ke kū'ē ʻana i ka tensile a me ke kū'ē ʻana i ka hopena) ma mua o ka hoʻoheheʻe ʻana.

ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ke kaomi: kūpono no ke kaomi kiʻekiʻe, ke mahana kiʻekiʻe a i ʻole nā ​​​​kūlana hana koʻikoʻi.

Sila ʻoi aku ka maikaʻi: He kiʻekiʻe ka nui o ka metala a ʻaʻole maʻalahi ke liki.

Kiwikā kila i hoʻolei ʻia:

ʻO ka paʻakikī haʻahaʻa: Hiki i ke ʻano hoʻolei ke loaʻa nā kīnā microscopic, e ʻoi aku ka maʻalahi o nā māwae ma lalo o ke kaumaha nui.

Kumukūʻai haʻahaʻa: kūpono no ka hana nui ʻana o nā kiwikā ʻano paʻakikī a nui paha.

III. ʻAno a me ke Kaumaha

Kiwikā kila i hana ʻia:

He maʻalahi ke ʻano o ke kūkulu ʻana, ʻo ka hapa nui he like a paʻa paha i ka hoʻolālā. ʻOi aku ka māmā o ke kaumaha (ma kahi o 20% a 30% ka māmā ma mua o nā kiwikā kila i hoʻolei ʻia me nā kikoʻī like).

Hoʻolei hao Wafer Pepeiao Valve Suppliers Kina:

Hiki ke hana ʻia nā ʻano paʻakikī (e like me nā kahawai kahe ʻano kūikawā, nā kino multi-cavity). ʻOi aku ke kaumaha a ʻoi aku ka mānoanoa o ka paia e hoʻopiha ai i ka nele o ka ikaika.

IV. Nā Kūlana Hana Pili

Kiwikā kila i hana ʻia:

Nā ʻōnaehana kaomi kiʻekiʻe a me nā ʻōnaehana wela kiʻekiʻe: e like me nā kikowaena mana, nā ʻoihana petrochemical, a me nā paipu mahu kaomi kiʻekiʻe.

Kaiapuni haʻahaʻa haʻahaʻa: e like me nā ʻōnaehana kinoea kūlohelohe liquefied (LNG), ʻoi aku ka maikaʻi o ka paʻakikī o ke kila i hoʻopaʻa ʻia.

Nā mea hoʻopilikia: nā wai ʻawahia, lapalapa a pahū (ma muli o ka hilinaʻi kiʻekiʻe).

Kiwikā hōʻoia Swing Iron China:

Nā kūlana hana maʻamau o ke kaomi waena a me ke kaomi haʻahaʻa: e like me ka mālama wai, nā paipu ʻoihana maʻamau, a me ka mahu kaomi haʻahaʻa.

Pāpaho ʻino: Hiki ke hoʻomaikaʻi ʻia ke kūpaʻa ʻana i ka ʻino ma ka hoʻohui ʻana i nā mea hao hao (e like me nā kiwikā kila kila i hoʻolei ʻia).

Nā kiwikā anawaena nui: Ke kaupalena ʻia ke kaʻina hana forging, ʻoi aku ka kūpono o ka hoʻolei ʻana no nā kino kiwikā nui.

V. Kumukūʻai a me ka Wā Hoʻouna

Nā kiwikā kila i hana ʻia:ʻO ke kumukūʻai o nā mea maka kiʻekiʻe, ka hoʻopukapuka nui ʻana i ka hana ʻana i nā make a me nā lako. Ka pōʻaiapuni hana lōʻihi, kūpono no nā ʻāpana liʻiliʻi a i ʻole nā ​​​​koi kūlana kiʻekiʻe. ʻO ke kumukūʻai maʻamau kiʻekiʻe.

Nā kiwikā kila i hoʻolei ʻia:He haʻahaʻa ke kumukūʻai o ka hoʻoheheʻe ʻana, e kūpono ai no ka hana nui ʻana. He pōkole ke kaʻina hana, a ʻoi aku ka hoʻokūkū o ke kumukūʻai.

VI. Nā Kūlana Maʻamau a me nā Māka

Kiwikā Hōʻoia Kina i hoʻopaʻa ʻia:

Nā kikoʻī: ASTM A105 (kila kalapona), A182 (kila kila ʻole), a pēlā aku. ʻO ka māka maʻamau e komo pū me ka huaʻōlelo "Forged".

Kiwikā puka hao hoʻolei:

Nā kikoʻī: ASTM A216 (kila kalapona), A351 (kila kila ʻole), a pēlā aku. ʻO ka māka maʻamau e komo pū me ka huaʻōlelo "Cast".
