Nā ʻano a me nā ʻokoʻa o nā milo

I kēia mau lā, ua huikau au i nā koi ʻokoʻa i nā kiʻi o nā mea kūʻai aku.I mea e ʻike ai i nā ʻokoʻa, ua loaʻa iaʻu ka ʻike kūpono a hōʻuluʻulu ʻia e like me lalo:

ʻO ke kaula paipu: hoʻohana nui ʻia no ka hoʻopili paipu, hiki ke paʻa ke kaula o loko a me waho, he paipu pololei a me ka pahu cone ʻelua mau kikoʻī.

ʻO ke kaula paipu maʻamau ka nui o kēia mau mea: NPT, PT, G a pēlā aku.

1.NPT thread: American standard 60 degere tapered paipu kaula

NPT: ʻO ka inoa piha ʻo National Pipe Thread, No ka US standard 60 degere tapered pipe thread, hoʻohana ʻia ma ʻAmelika ʻĀkau, komo i ka GB / T12716-1991.

2.PT (BSPT) kaula: European a Commonwealth 55 degere sila cone kaula

PT(BSPT): ʻO ka inoa piha ʻo British Standard Pipe Thread, he 55 degere i hoʻopaʻa ʻia i ke kaula cone, nona ka ʻohana thread Wyeth, i hoʻohana ʻia ma ʻEulopa a me nā ʻāina Commonwealth, i hoʻohana mau ʻia i ka ʻoihana wai a me ke kinoea, taper 1:16, komo GB / T7306-2000.

Loko G: 55 degere ʻaʻole i hoʻopaʻa ʻia i ka sila paipu

ʻO G he 55 degere non-threaded sealing tube thread, he ʻohana lola Wyeth.Hoʻopaʻa ʻia ʻo G, ʻo ia hoʻi ke kaula cylindrical.GB / T7307-2001.

ʻO ka ʻokoʻa ma waena o nā pae metric a me nā ʻīniha.

Hōʻike ʻia nā milo metric e ka pitch, ʻoiai ua hōʻike ʻia nā milo US-inihi e ka helu o nā milo i kēlā me kēia ʻīniha;

ʻO ka milo metric he ʻano niho like ʻole 60 degere, ʻo ka milo ʻīniha he isosceles 55 degere ʻano niho, ʻano niho ʻAmelika no ka pūhaka 60 degere ʻano niho.

Nā lola metric i nā ʻāpana metric (eg mm), nā lola hana ʻAmelika a me Pelekania i nā ʻāpana ʻīniha (eg ʻīniha)

Inā he ʻike ʻē aʻe aʻu i ʻōlelo ʻole ai, a i ʻole he kuhi hewa, e hoʻomaopopo iaʻu.

He 15 mau makahiki mākou i ʻike i ka mea hana ʻāpana mīkini CNC, kokoke i Shanghai.Inā loaʻa iā ʻoe ke kākoʻo RFQ, E KĀLU iā mākou e kiʻi i ka ʻōlelo manuahi.
