Hauv kev ua haujlwm txhua yam, pneumatic valve plays lub luag haujlwm tseem ceeb. Nws siv yuav tsum tsis tsuas yog technically muaj zog, tab sis kuj xyuas kom meej qhov zoo. Qhov no yuav tsum muaj kev saib xyuas tsim nyog thiab kev saib xyuas ntawm lub pneumatic valve, thiab kev tu lub valve xav tau Kev kho nws nrog tus cwj pwm kev tshawb fawb tuaj yeem ua rau lub valve tu ua haujlwm ua tiav nws cov txiaj ntsig thiab daim ntawv thov lub hom phiaj.
Kev ceev faj rau kev tu txhua hnub ntawm pneumatic li qub:
1. Lub valve yuav tsum muab cia rau hauv chav qhuav thiab qhov cua, thiab ob qho kawg ntawm txoj kev yuav tsum tau thaiv.
2. Valves uas tau khaws cia rau lub sijhawm ntev yuav tsum tau kuaj xyuas tsis tu ncua, cov av yuav tsum tau muab tshem tawm, thiab cov roj los tiv thaiv xeb yuav tsum tau siv rau qhov chaw ua haujlwm.
3. Tom qab kev teeb tsa, nws yuav tsum tau kuaj xyuas tsis tu ncua. Cov khoom tseem ceeb ntawm kev soj ntsuam yog: (1) Qhov hnav ntawm qhov sealing nto. (2) Kev hnav ntawm cov xov trapezoidal ntawm qia thiab qia txiv ntoo. (3) Txawm hais tias cov khoom ntim tau dhau los thiab siv tsis tau, yog tias puas lawm, nws yuav tsum tau hloov pauv raws sijhawm. (4) Tom qab lub valve raug kho thiab sib sau ua ke, kev ntsuas kev sib khi yuav tsum tau ua.
