Monga momwe dzinalo likusonyezera, ulusi wa chitoliro umatanthauza ulusi womwe umagwiritsidwa ntchito pa chitoliro. Pano, chitolirochi chikutanthauza chitoliro chodziwika bwino. Popeza mtundu uwu wa chitoliro umatchedwa chitoliro chodziwika bwino, ulusi wa chitoliro kwenikweni ndi ulusi wodziwika bwino. Ulusi wa chitoliro, monga njira yolumikizira chitoliro, umagwiritsidwa ntchito kwambiri polumikiza ndi kutseka mapaipi ang'onoang'ono ndi apakatikati omwe amanyamula zakumwa ndi mpweya. Pali mitundu itatu yodziwika bwino ya ulusi wa chitoliro. Ndi: ulusi wa NPT, ulusi wa BSPT, ndi ulusi wa BSPP.
Kusiyana kwakukulu pakati pa mitundu itatu ya ulusi:
| Ulusi wa Chitoliro | Ngodya | Taper/Parellel | Pamwamba & Pansi | Fomu Yotsekera | Muyezo |
| NPT | 60° | Yopindika | Pamwamba pathyathyathya, pansi pathyathyathya | Chodzaza | ASME B1.20.1 |
| BSPT | 55° | Yopindika | Chozungulira pamwamba, chozungulira pansi | Chodzaza | ISO7-1 |
| BSPP | 55° | Parellel | Chozungulira pamwamba, chozungulira pansi | Gasket | ISO228-1 |
Mfundo zotsekera ndi njira zotsekera mitundu itatu ya ulusi wa chitoliro
Kaya ndi ulusi wa chitoliro chotsekedwa cha 55 ° (BSPT) kapena ulusi wa chitoliro chotsekedwa cha 60 ° (NPT), ulusi wotsekeredwa uyenera kudzazidwa ndi sing'anga panthawi yokonza. Kawirikawiri, tepi yotsekeredwa ya PTFE imagwiritsidwa ntchito kukulunga ulusi wakunja, ndipo chiwerengero cha zokutira chimasiyana kuyambira 4 mpaka 10 kutengera makulidwe a tepi yotsekeredwa ya PTFE. Pamene mpata pakati pa pamwamba ndi pansi pa dzino uli wolunjika, umalimba ndi kulimbitsa kwa ulusi wa chitoliro. Ulusi wamkati ndi wakunja umakanikizidwa wina ndi mnzake, choyamba kuchotsa mpata pakati pa mbali zokanikizidwa. Kenako, pamene mphamvu yokanikizira ikuwonjezeka, pamwamba pa dzino pang'onopang'ono kumakhala wakuthwa, pansi pa dzino pang'onopang'ono kumakhala kopanda kanthu, ndipo mpata pakati pa pamwamba pa dzino ndi pansi pa dzino umatha pang'onopang'ono, kukwaniritsa cholinga choletsa kutayikira. Pakakhala kusintha kapena kusokoneza pakati pa pamwamba ndi pansi pa dzino, choyamba amakanikizana wina ndi mnzake, zomwe zimapangitsa kuti pamwamba pa dzino pang'onopang'ono pakhale kopanda kanthu ndipo pansi pa dzino pang'onopang'ono pakhale kolimba, kenako mbali ya dzino imalumikizana ndikuchotsa pang'onopang'ono mpatawo. Motero kukwaniritsa ntchito yotseka ya ulusi wa chitoliro.
Ulusi wa chitoliro chopanda chitoliro cha 55 ° (BSPP) wokha ulibe ntchito yotsekera, ndipo ulusiwo umangogwira ntchito yolumikizira. Chifukwa chake, gasket yotsekera imafunika kuti mutsekere nkhope kumapeto. Pali mitundu iwiri ya kutsekera nkhope kumapeto: imodzi ndi kugwiritsa ntchito gasket yathyathyathya pamwamba pa ulusi wamwamuna, ndipo inayo ndi kugwiritsa ntchito gasket yophatikizana (gasket yotanuka yopindika mkati mwa mphete yachitsulo) pamwamba pa ulusi wamkazi.
Kuti mudziwe zambiri zokhudza kuyitanitsa, chonde onani zomwe mwasankhamakatalogupaWebusaiti yovomerezeka ya HikelokNgati muli ndi mafunso aliwonse okhudza kusankha, chonde funsani akatswiri ogulitsa pa intaneti a Hikelok omwe amagwira ntchito maola 24 pa intaneti.
