1. Kab kab
Ib qho xwm txheej yog qhov ntau tig nce qia valve tsis tuaj yeem ntsia tau rau sab saum toj ntawm lub tshuab hluav taws xob, yog li kev saib xyuas tshwj xeeb yuav tsum tau them rau txoj kab uas hla ntawm lub qia valve thaum yuav khoom, xyuas kom meej tias nws tuaj yeem dhau los ntawm * * * valve qia txoj kab uas hla. Kuj tseem muaj qhov yuav tsum tau muaj nyob rau hauv txoj kab uas hla ntawm lub hollow tso zis ncej, uas yuav tsum tau loj tshaj li sab nraud txoj kab uas hla ntawm lub qia ntawm lub nce qia valve.
2. Kev ua haujlwm torque
Thaum muas hluav taws xob npauj npaim li qub thiab tab tom nrhiav rau lub chaw tsim khoom npauj npaim valve, thawj qhov kev txiav txim siab yog txoj kab uas hla ntawm lub valve qia, thiab qhov thib ob, kev ua haujlwm torque. Qhov no yog qhov tseem ceeb tshaj plaws nyob rau hauv peb xaiv cov khoom siv hluav taws xob valve. Hluav taws xob npauj npaim li qub feem ntau yog tswj los ntawm qhov loj ntawm stroke, torque, lossis axial thrust thaum ua haujlwm. Qhov ua tau zoo ntawm lub valve lub tshuab hluav taws xob feem ntau yog txiav txim siab los ntawm hom valve thiab seb lub cuab yeej puas ua haujlwm raws li tus qauv. Yog li ntawd, nws yog ib qho tseem ceeb thiab cov cuab yeej tseem ceeb. Yog li yog tias koj pom qhov tsim nyog npauj npaim valve qhov chaw tsim khoom thiab xaiv cov khoom siv hluav taws xob zoo, koj tuaj yeem tiv thaiv qhov tshwm sim ntau dhau.
3. Tso zis torque ntawm cov khoom siv hluav taws xob
Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tso zis torque ntawm lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob npauj npaim valve, kom ntseeg tau tias nws yog 1.2-1.5 ntawm kev khiav hauj lwm torque ntawm valve.
