ʻAno milo

Nui nā ʻano lola o nā mea ʻike puʻupuʻu, ma waena o ka NPT, PT, G a me M ka mea maʻamau, ʻo ia mau mea āpau he paipu.

ʻO ka NPT ka pōkole o National (American) Pipe Thread, nona ka 60-degree taper pipe thread o American pressure sensor standard a hoʻohana ʻia ma ʻAmelika ʻĀkau. Hiki ke loaʻa ke kūlana aupuni ma GB/T12716-1991.

ʻO PT ka pōkole o ka Pipe Thread, he 55-degere i hoʻopaʻa ʻia. No ka ʻohana thread o Wyeth pressure sensor a hoʻohana nui ʻia ma ʻEulopa a me nā ʻāina Commonwealth. Hoʻohana maʻamau ia i ka ʻoihana wai a me ke kinoea, a ua kuhikuhi ʻia ka taper e like me 1:16. Hiki ke loaʻa nā kūlana aupuni ma GB/T7306-2000.

ʻO G he 55-degere non-threaded sealing pipe thread, nona ka ʻohana milo o Wyeth pressure sensor. E kaha iā G no ka milo cylindrical. Hiki ke loaʻa nā kūlana aupuni ma GB/T7307-2001.

ʻO M he pae metric, no ka laʻana, ʻo M20*1.5 ke anawaena o 20mm a me kahi pitch o 1.5. Inā ʻaʻohe koi kūikawā o ka mea kūʻai aku, ʻo ka mīkini kaomi maʻamau ka M20 * 1.5 thread.

Eia kekahi, ʻo nā kaha 1/4, 1/2 a me 1/8 i loko o ke kaula e pili ana i ke anawaena o ka nui o ke kaula ma nā ʻīniha. Kāhea pinepine ka poʻe o ka ʻoihana i nā minuke nui o ka milo, hoʻokahi ʻīniha like me 8 mau minuke, 1/4 iniha like me 2 mau minuke, a pēlā aku. Me he mea lā ʻo G ka inoa nui o ke kaula paipu (Guan), a ʻo ka mahele o 55 a me 60 degere ka hana, ʻike nui ʻia ʻo ka pōʻai paipu. Hana ʻia ka milo mai ka ʻili cylindrical.

ʻIke mau ʻia ʻo ZG ma ke ʻano he paipu cone, ʻo ia hoʻi, ua mīkini ʻia ke kaula mai kahi ʻili conical, a ʻo ka hui puʻu wai maʻamau e like me kēia. Hōʻailona ʻia ka hae aupuni kahiko ʻo Rc.

Hōʻike ʻia nā milo metric e ka pitch, ʻoiai ʻo ʻAmelika a me Pelekania e hōʻike ʻia e ka helu o nā milo i kēlā me kēia ʻīniha, ʻo ia ka ʻokoʻa nui loa o nā loina sensor. ʻO nā milo metric he 60-degere like ʻole, ʻo nā lola Pelekane he 55-degere isosceles, a ʻo nā lola ʻAmelika he 60 degere. Hoʻohana nā lola metric i nā ʻāpana metric, a hoʻohana nā lola ʻAmelika a me Pelekane i nā ʻāpana Pelekane.

Hoʻohana nui ʻia ke kaula paipu no ka hoʻopili ʻana i nā paipu kaomi, a ua pili pono kona mau lola i loko a me waho. ʻElua ʻano o nā lola paipu ʻike puʻe: paipu pololei a me ka paipu liʻiliʻi. ʻO ke anawaena inoa e pili ana i ke anawaena o ka paipu kaomi pili. ʻIke loa, ʻoi aku ka nui o ke anawaena nui o ke kaula ma mua o ke anawaena nominal. ʻO 1/4, 1/2 a me 1/8 nā anawaena inoa o nā loina Pelekane, ma nā ʻīniha.
