Hoʻolauna mea kiwikā pōpō

He ʻokoʻa nā mea hana o ka valve pōpō e hoʻololi i nā kūlana hana like ʻole a me nā koi media. Eia kekahi mau mea hana valve pōpō maʻamau a me ko lākou mau ʻano:

1. Mea hao hao

Hao hoʻolei hina: kūpono no ka wai, ka mahu, ka ea, ke kinoea, ka ʻaila a me nā mea hana ʻē aʻe me ke kaomi maʻamau PN≤1.0MPa a me ka mahana -10℃ ~ 200℃. ʻO nā lama i hoʻohana pinepine ʻia ʻo HT200, HT250, HT300, HT350.

Hao hoʻolei palupalu: kūpono no ka wai, ka mahu, ka ea a me ka ʻaila me ke kaomi maʻamau PN≤2.5MPa a me ka mahana -30℃ ~ 300℃. ʻO nā lama i hoʻohana pinepine ʻia ʻo KTH300-06, KTH330-08, KTH350-10.

Hao ductile: Kūpono no PN≤4.0MPa, mahana -30℃ ~ 350℃ wai, mahu, ea a me ka ʻaila a me nā mea hana ʻē aʻe. ʻO nā papa i hoʻohana pinepine ʻia ʻo QT400-15, QT450-10, QT500-7. Eia kekahi, kūpono ka hao ductile kiʻekiʻe-silicon kūpaʻa waikawa no nā mea hana ʻino me ke kaomi inoa PN≤0.25MPa a me ka mahana ma lalo o 120℃.

2. Ke kila kila

Hoʻohana nui ʻia ka valve pōpō kila kila i nā pipeline waena a me ke kiʻekiʻe, me ke kūpaʻa wela ikaika, a hoʻohana nui ʻia i ka kemika, petrochemical, hoʻoheheʻe a me nā ʻoihana ʻē aʻe. Loaʻa i ka mea kila kila ke kūpaʻa maikaʻi i ka pala a me ka ikaika wela kiʻekiʻe, kūpono no nā ʻano media corrosive a me ke kaiapuni wela kiʻekiʻe.

3. Mea keleawe

Mea hoʻohuihui keleawe: Kūpono no ka wai PN≤2.5MPa, ka wai kai, ka oxygen, ka ea, ka ʻaila a me nā mea ʻē aʻe, a me ka mahana o -40℃ ~ 250℃ mea mahu. ʻO nā papa i hoʻohana pinepine ʻia ʻo ZGnSn10Zn2 (keleawe tin), H62, Hpb59-1 (keleawe), QAZ19-2, QA19-4 (keleawe alumini) a pēlā aku.

Keleawe wela kiʻekiʻe: kūpono no nā huahana mahu a me ka ʻaila me ke kaomi maʻamau PN≤17.0MPa a me ka mahana ≤570℃. ʻO nā lama i hoʻohana pinepine ʻia ʻo ZGCr5Mo, 1Cr5Mo, ZG20CrMoV a pēlā aku.

4. Mea kila kalapona

He kūpono ke kila kalapona no ka wai, ka mahu, ka ea, ka hydrogen, ka ammonia, ka naikokene a me nā huahana petroleum me ke kaomi maʻamau PN≤32.0MPa a me ka mahana -30℃ ~ 425℃. ʻO nā papa i hoʻohana pinepine ʻia ʻo WC1, WCB, ZG25 a me ke kila kiʻekiʻe 20, 25, 30 a me ke kila kūkulu haʻahaʻa 16Mn.

5. Mea palakiko

Hana ʻia ka kiwikā poepoe plastik i ka plastik no nā mea maka, kahi kūpono no ka interception o ke kaʻina hana lawe me nā mea ʻino. Hoʻohana pinepine ʻia nā plastik hana kiʻekiʻe e like me PPS a me PEEK ma ke ʻano he mau noho kiwikā poepoe e hōʻoia i ka ʻole o ka pala ʻana o ka ʻōnaehana e nā kemika i loaʻa i ka hala ʻana o ka manawa.

6. Mea seramika

ʻO ka kiwikā pōpō seramika kahi ʻano mea kiwikā hou, me ke kūpaʻa maikaʻi loa i ka pala a me ke kūpaʻa ʻana i ka ʻaʻahu. ʻOi aku ka mānoanoa o ka pūpū kiwikā ma mua o nā koi o ke kūlana aupuni, a ʻo nā mea kemika a me nā waiwai mechanical o ka mea nui e hoʻokō i nā koi o ke kūlana aupuni. I kēia manawa, hoʻohana ʻia ia i ka hana mana wela, ke kila, ka ʻaila, ka hana pepa, ka ʻenekinia olaola a me nā ʻoihana ʻē aʻe.

7. Nā mea kūikawā

Ke kila wela haʻahaʻa: kūpono no ke kaomi maʻamau PN≤6.4MPa, mahana ≥-196℃ ethylene, propylene, kinoea kūlohelohe wai, naikokene wai a me nā mea hana ʻē aʻe. ʻO nā lama i hoʻohana pinepine ʻia ʻo ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 a pēlā aku.

Ke kila kila kūpaʻa waikawa: kūpono no ka waikawa nitric, ka waikawa acetic a me nā mea ʻē aʻe me ke kaomi maʻamau PN≤6.4MPa a me ka mahana ≤200℃. ʻO nā lama maʻamau ʻo ZG0Cr18Ni9Ti, ZG0Cr18Ni10 (kū'ē i ka waikawa nitric), ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti (kū'ē i ka waikawa a me ka urea) a pēlā aku.

I ka hōʻuluʻulu manaʻo, pono e hoʻoholo ʻia ke koho ʻana o ka mea o ka valve pōpō e like me nā kūlana hana kikoʻī a me nā koi waena e hōʻoia i ka hana maʻamau a me ke kūpaʻa lōʻihi o ka valve.
