Mtundu wa ulusi

Pali mitundu yambiri ya ulusi wa sensors pressure, yomwe NPT, PT, G ndi M ndizofala, zonsezo ndi ulusi wa chitoliro.

NPT ndiye chidule cha National (American) Pipe Thread, yomwe ndi ya 60-degree taper pipe ulusi wa American pressure sensor standard ndipo imagwiritsidwa ntchito ku North America.Muyezo wadziko lonse umapezeka mu GB/T12716-1991.

PT ndiye chidule cha Pipe Thread, chomwe ndi ulusi wa 55-degree conical wosindikizidwa.Ndi ya banja la ulusi la Wyeth pressure sensors ndipo imagwiritsidwa ntchito kwambiri ku Europe ndi mayiko a Commonwealth.Amagwiritsidwa ntchito kwambiri m'makampani amadzi ndi gasi, ndipo tepiyo imatchulidwa kuti 1:16.Miyezo ya dziko imapezeka mu GB/T7306-2000.

G ndi ulusi wa 55-degree wopanda ulusi wosindikiza, womwe ndi wa banja la Wyeth pressure sensor.Mark G pa ulusi wozungulira.Miyezo ya dziko imapezeka mu GB/T7307-2001.

M ndi ulusi wa metric, mwachitsanzo, M20 * 1.5 imasonyeza kutalika kwa 20mm ndi phula la 1.5.Ngati kasitomala alibe zofunikira zapadera, sensor yokakamiza nthawi zambiri imakhala M20 * 1.5 ulusi.

Kuonjezera apo, zizindikiro za 1/4, 1/2 ndi 1/8 mu ulusi zimatanthawuza kukula kwa ulusi mu mainchesi.Anthu mumakampani nthawi zambiri amatcha ulusi wa mphindi, inchi imodzi ndi mphindi 8, 1/4 inchi ndi mphindi 2, ndi zina zotero.G ikuwoneka ngati dzina lambiri la ulusi wa chitoliro (Guan), ndipo kugawanika kwa madigiri 55 ndi 60 kumagwira ntchito, komwe kumatchedwa bwalo la chitoliro.Ulusiwo umapangidwa kuchokera pamwamba pa cylindrical.

ZG imadziwika kuti chitoliro cha chitoliro, ndiye kuti, ulusi umapangidwa kuchokera pamwamba, ndipo kuphatikizika kwa chitoliro chamadzi ndi chotere.Muyezo wakale wadziko umalembedwa kuti Rc.

Ulusi wa metric umawonetsedwa ndi phula, pomwe ulusi waku America ndi waku Britain umawonetsedwa ndi kuchuluka kwa ulusi pa inchi, komwe ndiko kusiyana kwakukulu kwa ulusi wa sensor sensor.Ulusi wa Metric ndi ulusi wa 60-degree equilateral, ulusi waku Britain ndi 55-degree isosceles ulusi, ndipo ulusi waku America ndi 60 madigiri.Ma metric threads amagwiritsa ntchito mayunitsi a metric, ndipo ulusi waku America ndi waku Britain amagwiritsa ntchito mayunitsi a Chingerezi.

Ulusi wa chitoliro umagwiritsidwa ntchito makamaka kulumikiza mapaipi opanikizika, ndipo ulusi wake wamkati ndi wakunja umagwirizana kwambiri.Pali mitundu iwiri ya ulusi wa chitoliro cha pressure sensor: chitoliro chowongoka ndi chitoliro cha tapered.M'mimba mwake mwadzina imatanthawuza kukula kwa payipi yolumikizira yolumikizidwa.Mwachiwonekere, m'mimba mwake waukulu wa ulusi ndi waukulu kuposa m'mimba mwake mwadzina.1/4, 1/2 ndi 1/8 ndi ma diameter mwadzina a ulusi wa Chingerezi, mainchesi.
