YF08 high-pressure porous manual chosinthika valve valve

Pressure sensor NPT ndiye chidule cha ulusi wapaipi wadziko (American).

Ulusi wa 60-degree taper, womwe ndi wa American pressure sensor standard, umagwiritsidwa ntchito ku North America. Muyezo wadziko lonse umapezeka mu GB/T12716-1991.

PTndi chidule cha Pipe Thread, chomwe ndi 55-degree yosindikizidwa chitoliro cha chitoliro. 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 taper imatchulidwa kuti 1: 16. Miyezo ya dziko imapezeka mu GB/T7306-2000.

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

Mndi ulusi wa metric, mwachitsanzo, M20 * imasonyeza m'mimba mwake 20mm ndi phula la 0. Ngati kasitomala alibe zofunikira zapadera, mphamvu yamagetsi yopangidwa ndi Yuyang Company nthawi zambiri imakhala M20 * 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.

ZGAmadziwika kuti chulu cha chitoliro, ndiye kuti, ulusi umapangidwa kuchokera pamwamba pa conical, ndipo zolumikizira zolumikizirana ndi chitoliro chamadzi zimafanana ndi izi. Ulusi wa metric wolembedwa ngati Rc muyeso wakale wadziko umawonetsedwa ndi phula, ndipo ulusi wopangidwa ku United States ndi Britain umawonetsedwa ndi kuchuluka kwa ulusi pa inchi. Uku ndiye kusiyana kwakukulu pakati pa ulusi wa sensor sensor. Ulusi wa metric ndi 60-degree equilateral, ulusi waku Britain ndi 55-degree isosceles, ndipo ulusi waku America ndi 60-degree. Ma metric threads amagwiritsa ntchito mayunitsi a metric, ndipo ulusi waku America ndi waku Britain amagwiritsa ntchito mayunitsi a Chingerezi.
