Hoʻolauna Huahana
Loaʻa i nā mea hoʻohui NPT ka mea lanakila ma ka liʻiliʻi loa he NPT kaula kāne a wahine paha i hoʻohui ʻia ma ka mea hoʻohui, ʻo NPT ʻo ʻAmelika National pipe tapered thread, ʻike ʻia ʻo ANSI/ASME B1.20.2M paipu kaula.
Aia nā hiʻohiʻona ma lalo o ka pae NPT:
1. He palahalaha ka ʻoki ʻana o nā aʻa a me nā piko o ka milo
2.60° ka huina milo
3. ʻO ka angle ma waena o ka taper a me ke koʻikoʻi waena o ke kaula paipu he 1 ° 47'24 "
4. Ua ana ʻia ka pitch thread i kēlā me kēia ʻīniha.
No ka mea he palahalaha ka ʻoki ʻana o ke kaula NPT o nā aʻa a me nā piko o ke kaula, ʻokoʻa ia me ka NPTF, no laila pono e hoʻohana ʻia kahi lipine sealant PTFE e hōʻoia i kahi sila leak-free, a laila hāʻawi i kahi sila kūpono no nā mea hoʻohui e hoʻohana ana i nā wai hydraulic.
ʻO ka nui o nā kaula NPT no nā mea hoʻohui Winner: 1/8”-27, 1/4”-18, 3/8”-18, 1/2”-14, 3/4”-14, 1”-11.5, 1.1/ 4”-11.5, 1.1/2”-11.5, 2”-11.5.
Pehea e ʻike ai he thread NPT a hoʻoholo i ka nui o ke kaula?
1. Nānā makaʻala i ke kaula a he liʻiliʻi ia, a i ʻole e hoʻohana i ka caliper e ana i ke anawaena o waho o ka milo a i ʻole ke anawaena liʻiliʻi o ke kaula kūloko ma kahi kūlana lōʻihi a ʻike ʻia ʻokoʻa ke anawaena a hālāwai me 1:16 taper, a i ʻole hoʻohana pololei i kahi 1:16 ana cone.
2.E hoʻohana i ka caliper e ana i ke anawaena o ke kūlana laina kumu.E ana i ke anawaena o ka milo me ka caliper ID/OD, ana ke anawaena o ka milo waho ma ke anawaena o waho, a e paa ana i ke anawaena ma kahi kihi iki no ka heluhelu pololei ana, no ka mea, ua anaia ke kaula kuloko ma ke anawaena o loko, a e paa ana i ke anawaena. ke kaula no ka heluhelu wahine pololei loa.
3. E ana i nā lola no ka ʻīniha (TPI) a i ʻole ka pitch.E like me ke anawaena ana a me ka hoohana ana i ke anawaena pili pili, e hoao i na ana milo like'ole a hiki i ka hoomaopopo ana i ke kupono loa, e hookomo i na lola e like me ka hiki, ua oi aku ka nui o ke kaula i hookomoia, oi aku ka pololei o ka heluhelu ana.E hoʻopaʻa i ka mea hoʻopili/kokoko a me ka milo pitch ana a hiki i ke kukui, e ʻimi ana i nā āpau ma waena o ke ana a me ka wili, ʻoi aku ka maʻalahi o kēia ʻike ʻia ma kahi kuʻekuʻe milo waho ma mua o kahi kaula kuʻi.A i ʻole e ana pololei i ka mamao o ʻelua mau kaula piko
no ka mea, ʻoi aku ka nui o ka nui hoʻokahi hiki ke loaʻa i nā ana o ke kaula like.Aia ma lalo ka ʻikepili hoʻohālikelike ma waenaNʻO ke kaula PT vs ke kaula BSPT, ua like ia, no laila pono e makaʻala ʻaʻole e hui a kuhihewa paha.
