NPT (National Yeeb Nkab Xov) yog ib hom kab tapered uas siv dav hauv cov yeeb nkab sib txuas. Nws cov qauv tapered muab kev sib khi zoo heev, ua rau nws tsim nyog rau kev thauj khoom ua kua thiab roj. NPT threads muaj 60-degree hniav lub kaum ntse ntse thiab muaj nyob rau hauv ob sab hauv thiab sab nraud xov ntaub ntawv.
Cov yam ntxwv tseem ceeb ntawm NPT couplings yog raws li hauv qab no:
1. Tapered Thread: NPT couplings siv cov xov tapered, muab kev sib khi zoo heev thiab ua kom lub raj xa dej nruj, tiv thaiv cov xau.
2. Self-Sealing: Cov xov ntawm NPT coupling tsim ib tus kheej- sealing qauv nrog cov yeeb nkab xov, tshem tawm qhov xav tau gaskets lossis sealants, ua kom yooj yim rau cov txheej txheem installation.
3. High Pressure Resistance: NPT couplings yog haum rau siab -siab ib puag ncig thiab muaj peev xwm tiv taus siab heev.
4. Kev Tiv Thaiv Kub Kub: NPT txuas tuaj yeem ua haujlwm nyob rau hauv siab - qhov kub thiab txias thiab tsis yooj yim cuam tshuam los ntawm thermal expansion thiab contraction.
5. Yooj yim Disassembly: NPT couplings tuaj yeem rov ua dua, ua kom yooj yim txij nkawm thiab hloov cov yeeb nkab.
Daim Ntawv Thov Cheeb Tsam ntawm NPT Coupling
NPT couplings yog dav siv nyob rau hauv lub tshuab nqus tsev pipelines, feem ntau yog rau txuas lub tshuab nqus tsev twj, lub tshuab nqus tsev twj, li qub, thiab lwm yam khoom siv nqus tsev vacuum. Lawv ua hauj lwm raws li ob qho tib si connectors thiab ntsaws ruaj ruaj nyob rau hauv lub tshuab nqus tsev vacuum systems, kom ntseeg tau tias ib txwm ua hauj lwm ntawm tag nrho cov system.
Nyob rau hauv lub tshuab nqus tsev raj, NPT couplings feem ntau yog siv nyob rau hauv ua ke nrog nrog rau lwm yam threaded yeeb nkab kev twb kev txuas (xws li BSP couplings, NPTF couplings, thiab lwm yam) kom tau raws li qhov sib txawv kev twb kev txuas. NPT couplings tuaj yeem txuas cov kav dej ntawm cov kab sib txawv, ua rau cov raj xa dej yooj yim dua.
