Qhov zoo ntawm Npauj Npaim Valves:
1. Qhov qhib thiab kaw ntawm npauj npaim valve yog qhov yooj yim thiab ceev, txuag zog, thiab cov dej tsis kam yog me me, yog li nws tuaj yeem ua haujlwm ntau zaus.
2. Lub npauj npaim valve yog qhov yooj yim hauv cov qauv, me me, luv luv hauv cov qauv ntev, me me thiab lub teeb hauv qhov hnyav, thiab haum rau qhov loj-inch li qub.
3. Lub npauj npaim valve tuaj yeem thauj cov av nkos, thiab cov kua uas ntim ntawm lub qhov ncauj ntawm cov yeeb nkab yog qhov tsawg tshaj plaws.
4. Lub npauj npaim valve tuaj yeem ua tiav zoo sealing nyob rau hauv qis qis.
5. Kev tswj hwm kev ua haujlwm ntawm npauj npaim valve yog qhov zoo.
6. Thaum qhib tag nrho, qhov ua tau zoo ntawm qhov chaw ntawm lub rooj zaum valve yog qhov loj dua, thiab cov dej tsis kam yog me dua.
7. Qhov qhib thiab kaw torque yog qhov me me, vim hais tias daim hlau npauj npaim ntawm ob sab ntawm lub rotating ncej yog qhov sib npaug ntawm qhov nruab nrab, thiab cov kev taw qhia ntawm lub torque yog qhov sib txawv, yog li qhov qhib thiab kaw kuj tseem ua haujlwm- txuag.
8. Lub sealing nto khoom ntawm lub npauj npaim valve feem ntau yog ua los ntawm roj hmab lossis yas, yog li qhov kev sib khi tsis zoo yog qhov zoo.
9. Lub npauj npaim valve yog ib qho yooj yim rau nruab.
10. Kev ua haujlwm yog hloov tau thiab txuag kev ua haujlwm, thiab kev siv phau ntawv, hluav taws xob, pneumatic thiab hydraulic tuaj yeem xaiv.
