Hom thiab qhov sib txawv ntawm cov xov

Tsis ntev los no, kuv tau tsis meej pem los ntawm cov xov sib txawv hauv cov neeg siv khoom sib txawv.Txhawm rau txheeb xyuas qhov sib txawv, kuv tau nkag mus rau cov ntaub ntawv tseem ceeb thiab sau cov ntsiab lus hauv qab no:

Cov yeeb nkab xov: feem ntau yog siv rau cov yeeb nkab kev sib txuas, cov xov sab hauv thiab sab nraud tuaj yeem nruj, nws muaj cov raj ncaj thiab lub khob raj ob qhov tshwj xeeb.

Cov yeeb nkab xov feem ntau suav nrog cov hauv qab no: NPT, PT, G thiab lwm yam.

1.NPT xov: American standard 60 degree tapered yeeb nkab xov

NPT: lub npe tag nrho yog National Pipe Thread, belongs rau US tus qauv 60 degree tapered yeeb nkab xov, siv nyob rau hauv North America, nkag mus rau GB / T12716-1991.

2.PT (BSPT) xov: European thiab Commonwealth 55 degree kaw lub khob hliav qab xov

PT (BSPT): tag nrho lub npe yog British Standard Yeeb Nkab Xov, yog 55 degrees kaw lub khob hliav qab xov, belongs rau Wyeth xov tsev neeg, siv nyob rau hauv cov teb chaws Europe thiab Commonwealth lub teb chaws, feem ntau siv nyob rau hauv dej thiab roj yeeb nkab kev lag luam, taper 1:16, nkag mus rau GB / T7306-2000.

G xov: 55 degree non-threaded sealing yeeb nkab xov

G yog 55 degree tsis-threaded sealing raj xov, yog Wyeth xov tsev neeg.Cim ua G, txhais tau hais tias cov xov cylindrical.GB / T7307-2001.

Qhov txawv ntawm metric threads thiab nti threads:

Metric threads yog sawv cev los ntawm suab, thaum US-inch threads yog sawv cev los ntawm cov xov tooj ntawm ib nti;

Metric xov yog sib npaug 60 degrees hniav hom, ntiv tes xov yog isosceles 55 degrees hniav hom, American xov rau lub duav 60 degrees hniav hom.

Metric threads nyob rau hauv metric units (xws li hli), American thiab British ua threads nyob rau hauv nti units (piv txwv li nti)

Yog tias muaj lwm yam ntaub ntawv kuv tsis tau hais, lossis yog tias muaj qhov yuam kev, qhia rau kuv paub.
