Niki NPT?

NPT isobanura National Pipe Taper, ikaba isanzwe yo muri Amerika kubudodo bukoreshwa ku miyoboro no mu miyoboro hagamijwe gufunga. Urudodo rwa NPT rwashizweho kugirango rutange kashe idasohoka iyo ikoreshejwe hamwe na kashe ya kashe, nka kaseti ya Teflon cyangwa dope. Icyuma gifata kumurongo wa NPT kibemerera gukora kashe iyo ihujwe nundi mugozi.

Ibintu byingenzi biranga insanganyamatsiko ya NPT harimo:

1. Inyandiko:Diameter yo hanze (OD) yumurongo igabanukaho gato kuva itangira kugeza iherezo ryurudodo. Iyi taper, mubisanzwe 1/16 santimetero imwe, ifasha mukurema kashe ifatanye nkuko ibice bifatanyirijwe hamwe.

2. Inguni.

3. Ikibanza: Ikibanza (umubare wudodo kuri santimetero) kiratandukanye bitewe nubunini bwa nominal. Kurugero, 1/8-inimero NPT ifite imigozi 27 kuri santimetero, mugihe NPT-2-ifite 11,5 kuri 11.

4. Ikidodo:Kugirango ushireho kashe ikwiye, kashe yomudodo igomba gukoreshwa. Bitabaye ibyo, birashoboka cyane ko yameneka kuko guhuza ibyuma-byuma byonyine ntibikora kashe ihagije.

5. Gukomera amaboko:Urudodo rwa NPT rugomba kubanza gufatanwa intoki, hanyuma ugahabwa izindi mpinduka hamwe nu mugozi kugirango ugere kashe ikwiye. Umubare winyongera wongeyeho bitewe nubunini bukwiranye nibikoresho; muri rusange, birasabwa 1.5 kugeza kuri 3.5 kurenza urutoki.

Urudodo rwa NPT rusanzwe rukoreshwa mumazi, hydraulics, na sisitemu ya pneumatike, mubindi, aho bisabwa guhuza umutekano, bitamenyekana. Hariho kandi verisiyo yumye yitwa NPTF (National Pipe Taper Fuel) yagenewe gutanga kashe ya mashini idakeneye kashe yihariye, nubwo porogaramu zimwe zishobora gusaba kashe kugirango hongerwe umutekano.

Kubindi bibazo byose bijyanye nibikoresho bya NPT cyangwa urutonde rwibicuruzwa byacu, nyamuneka twandikire.
