Siv cov cuab yeej tsim nyog los loosen thiab tshem tawm cov bolts lossis fasteners uas tuav lub valve thiab cov kav dej.
Kev ceeb toom sov so: Ua tib zoo saib xyuas qhov kev npaj thiab kev taw qhia ntawm cov khoom rau kev rov sib dhos.
3. Tshawb xyuas seb puas muaj kev puas tsuaj:
Tom qab tshem lub valve tawm lawm, xyuas seb txhua yam khoom puas muaj cov cim qhia tias puas tsuaj, puas hnav, lossis puas xeb. Xyuas lub disc, stem, lub rooj zaum, cov foob thiab lwm yam khoom cuam tshuam seb puas muaj kab nrib pleb, puas xeb lossis puas hloov pauv.
Cov txheej txheem ntawm kev rhuav tshem lub npauj npaim valve tau qhia hauv video hauv qab no.
4. Kho thiab hloov cov khoom tsis zoo
Yog tias muaj cov khoom tsis huv nyob nruab nrab ntawm lub phaj valve thiab lub rooj zaum valve, ua ntej tshem tawm cov khoom tsis huv thiab saib seb lub rooj zaum valve puas deformed vim qhov no.
Yog tias lub qia valve deformed, nws tuaj yeem raug tshem tawm thiab ncaj.
Yog tias pom muaj ib feem twg puas lawm los yog hnav tsis tau kho, yuav tsum tau hloov nrog ib qho tshiab uas tsim nyog. Xyuas kom tseeb tias qhov hloov pauv ntawd muaj tib yam li qhov qub. Cov feem uas yuav tsum tau hloov suav nrog cov foob, cov qia, thiab O-rings.
5. Rov sib dhos lub valve
Rov muab lub qhov valve rov sib dhos ua ke raws li qhov kev txiav txim rov qab ntawm kev rhuav tshem. Ntxuav thiab roj rau cov khoom raws li qhov xav tau kom ntseeg tau tias kev ua haujlwm du thiab kev sib khi zoo. Nias lub bolts lossis fasteners, ceev faj kom tsis txhob nias dhau kom tsis txhob ua puas rau cov khoom valve lossis cov nto.
6. Kev Ntsuas
Tom qab lub valve tau rov sib dhos ua ke lawm, yuav tsum tau kuaj xyuas seb puas ua haujlwm tau zoo ua ntej muab rov qab siv dua. Ua ntej, sim ua qhov kev sim siab kom pom qhov ua haujlwm ntawm lub valve thiab xyuas seb puas muaj qhov xau lossis qhov tsis zoo. Xyuas kom tseeb tias lub valve qhib thiab kaw.
7. Kev teeb tsa
Cov txheej txheem rov nruab dua kom raug yog qhov tseem ceeb rau kev ua tiav qhov kev ua haujlwm ntawm lub valve zoo tshaj plaws, ua kom lub valve ntev dua, thiab ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
