Ua makemake nuiʻia nā mea e like me ka dn, Pn, ½, ʻIliʻili, a me nā leka cwp ma kahi kumu kūʻai? ʻO ka pīhoihoi e pili ana i nā hōʻailona ma ke kino valve a me nā leka'ē aʻe eʻikeʻia? E loaʻa iā mākou aʻimi.

ʻO nā māka ma kahi Valve e hōʻike pinepine i nāʻike koʻikoʻi e like me kona nui, ke koiʻana a me nā helu o ka mahana, Nā Kūlana Kūʻai, Haole, Kaena Light, a me nā hōʻoia. ʻO kēia mau kiko'ī he vital ma ke koho kūpono, hoʻopiha, a me ka hana, e hōʻoia ana i ka valve i hoʻohana ponoʻia a pololei hoʻi.

1. ʻO ka hōʻailona nui o ka hōʻailona:“Dn” a “½” Hapa a iʻole nā ​​leka ma Valve

ʻO ka nui o ka nui o kānaʻano helu nui loa, e hōʻike ana i ka hua nomimal o ka paipu i kūpono. ʻO ia ka mea maʻamau ma kekahi o nā alaʻelua:

• Dn (Ana Paula): Ka diameter koho, he hui metric (I nā lālailsiters) hoʻohanaʻia ma ka International (Iso) a me ka European / Kina (Hoʻokahi / gb) kūlā. ʻo kahi laʻana, DN50ʻo ia ka meaʻo Valve no ka paipu me ka 50 mm nominial ka hema.
• NPS (ʻO ka nui o Nominal paila): He unahi imperial (Ma nā Iniha) hoʻohanaʻia ma nā kūlanaʻAmelika (Asme / Ansi). ʻo kahi laʻana, 4″ a iʻole nps 4 e hōʻike ana i ka Valve no kahi paipa 4-inch. I kekahi manawa, ʻO ka helu wale nō, e like me 4, e hoʻoleiʻia ma ke kino.

2. ʻO keʻano o ka hōʻailona loiloi haʻahaʻa: “Pn” a me nā helu ma Valve

Hōʻike ka loiloi ikaika i ka hoʻoikaika nui loa e hiki i keʻano o ka valve ke palekana i kahi mahana i kahi mahana a he koʻikoʻi no ke kohoʻana.

• Iso / en / gb kūlana: Hoʻohana “Keʻano” (Pn), kahi i pae ai ka papa. ʻO ka waiwai PN e hōʻike i ka helu kaomiʻana ma ka mahana o ka lumi. Nā hiʻohiʻona: PN16, PN40.
• Meme/Ansi Kūlā: Hoʻohana a “Papa hana” 'ōnaehana'ōnaehana, kākauʻia e like me ka papa, Cl, Lb, Oole #. Nā hiʻohiʻona i loaʻa i ka papa 150, 300#, Oole 150 Lb. Hōʻike kēia i kahi papa o keʻano, ʻaʻole he waiwai paʻa mau.
• Nā Kūlana Nui:
  • ʻIliʻili (Wai, Pono, Aila): Hōʻike i ka helu kaomiʻana ma PSI no ka wai, pono, a me ka lawelaweʻana i ka lawelaweʻana i nā mahana ambied. Hoʻoloholo: 600 ʻIliʻili.
  • Cwp (Ke kaomiʻana i keʻano): Ke kūlike o ka wog, e hōʻike pū ana i ke kaomi kūpono loa i keʻano o keʻano ambied. Hoʻoloholo: 1000 Cwp.

3. ʻO ka hōʻailona hōʻailona hōʻailona:

ʻO ke code waiwai kahi o nā hōʻailona nui loa, e wehewehe ana i ka waiwai o ka hoʻoikaika nui-mau'āpana e like me ke kino a me ka bonnet.

• Kālā Capren Carbon: ʻO WCB ka papa maʻamau maʻamau.
• Hoʻolei iā stienceless kila: CF8(like me 304 SS), Cf8m(316 SS), Cf3(304L), Cf3m(316L).
• Hona i ke kiloki: Wc6, wc9(chrome-moly steel no ka lawelawe kiʻekiʻe kiʻekiʻe).
• Nā mea waiwai: A105(ʻaihue kīwī), A182 F316(kila kohu ʻole).
• Alakaʻiʻia: “Lf” ʻo ia ka mea e alakaʻi ai i nā lako, me ke keleawe a me ke keleawe.

4. ʻO nā hōʻailona media media:

ʻO ka hana lawelawe kūikawā (E.g., “Sulfuric acid”) ʻaʻole i hōʻailonaʻia. Kūpono no kahi medium i hoʻoholoʻia e ka valveMea waiwai. Akā naʻe,, No kekahi mau lawelawe kūikawā, Hoʻohanaʻia nā hōʻailona kūikawā:

• ʻIliʻili: He kūpono no ka wai kai wai
• S: Steam medium
• G: ʻO ka lāʻau lapaʻau

5. ʻO Valve Brand Markting:

ʻO kēia e pili ana i ka kālepa kālepa o ka mea hana, Kumukora, a iʻole ka inoa inoa inoa, hoʻohanaʻia e hoʻomaopopo i ka mea hana. ʻo kahi laʻana, “BMAG” a iʻole he hōʻailona kūikawā.

6. ʻO ke alanui holo alanui e hōʻailona ana:

No nā kumuwaiwai kūponoʻole e like me nā valbe blabe, E nānā i nā Valves, a me nā alaloa, kahi hōʻailona hōʻailona liʻiliʻi(→) pono e hoʻolei a hoʻopaʻaʻia paha ma ke kino. Hōʻike kēia pua i ke kuhikuhi pololei o ka kahe. Hiki i ka hoʻonohonoho hewa ke alakaʻi i ka hewa a iʻole ka hōʻino.

7. Valve hōʻoia hōʻailona hōʻailona:

Hōʻike kēia mau hōʻailona i ka hoʻopiliʻana o ka valve i nā hoʻoponopono a iʻole nā ​​kūlana a me nā kūlana hana.

• C Ce: Pōkole no “AUPALANOLA,” e hōʻike ana i ka hoʻokōʻana me ka palekana palekana, olakino, a me nā kūlana palekana kūloko, koiʻia no ke komoʻana o ka mākeke maʻEulopa.
• Kii: ʻO kaʻike pūnaeweleʻoʻAmelikaʻAmelika Hui PūʻIaʻoʻAmelika Hui PūʻIa i loaʻa ma nā Valves i hoʻohanaʻia i loko o ka aila a me nāʻoihana.
• CSA: ʻO ka Hui PūʻIa Kanada, He hōʻoia e pono ai e kūʻai aku i nā mea hana ma Kanada.
• UL: ʻO nā papa hana lalo, ʻO ka hōʻoia ka palekana palekana i hāʻawiʻia e nā mea hana ma lalo o nā mea kākau, heʻoihanaʻepekema palekana honua. E hōʻailona ia i kahi huahana, hui, a iʻole i hōʻikeʻia ka'ōnaehana a hoʻokō i nā kūlana palekana palekana.
