Cov Ntsiab Lus Tseem Ceeb ntawm Cov Kev Cai Teeb tsa Pipeline Valve

I. Kev Npaj Ua Ntej Kev Teeb Tsa

1. Tshawb xyuas tus qauv qhia txog lub valve, qib siab, thiab kev qhia txog kev ntws kom paub tseeb tias nws ua tau raws li qhov yuav tsum tau tsim.

2. Xyuas seb lub qhov ntawm lub cev valve huv si thiab tshem tawm cov khoom tiv thaiv thiab cov khoom txawv teb chaws.

3. Cov qhov txuas sib txuas uas vuam tau yuav tsum tau ua ntej nrog cov grooves, thiab cov qhov txuas flange yuav tsum tau kuaj xyuas qhov kev ncaj ncees ntawm qhov chaw sealing.

II. Kev Tswj Xyuas Kev Teeb Tsa

1. Lub qhov dej hauv ntiaj teb thiabntsug nqa lub valve xyuasyuav tsum tau teeb tsa nruj nreem rau hauv qhov kev taw qhia uas qhia los ntawm tus xub ntawm lub cev valve.

2. Hauv paus ntsiab lus,lub valve uas tsis nce siab, dej hom npauj npaim valve, thiab lub pob li qub tuaj yeem ntsia tau rau ob qho kev taw qhia, tab sis yuav tsum tau them sai sai rau qhov yooj yim ntawm kev ua haujlwm.

3. Cov twj siv hluav taws xob / pneumatic yuav tsum tau tseg qhov chaw rau kev ua haujlwm thiab kev saib xyuas ntawm cov actuator.

III. Cov Lus Qhia Txog Kev Teeb tsa Vuam

1. Lub qhov (valve) vuam yuav tsum tau qhib ib nrab thaum lub sijhawm vuam kom tiv thaiv kev sib tsoo los ntawm kev hloov pauv thermal.

2. Siv argon arc vuam los ua lub hauv paus, thiab tswj qhov kub ntawm cov txheej txheem kom tsis txhob tshaj qhov ntsuas kub ntawm lub valve.

3. Tom qab vuam, lub valve yuav tsum tau kuaj xyuas kom paub tseeb tias nws qhib thiab kaw li qub.

IV. Cov Ntsiab Lus Tseem Ceeb ntawm Kev Sib Txuas Flange

1. Cov nplaim flange sealing tseem sib luag, thiab qhov siab tshaj plaws uas tso cai tsis pub tshaj 0.15% ntawm lub flange sab nraud.

2. Lub gasket yuav tsum tau muab tso rau hauv nruab nrab, cov bolts yuav tsum tau nruj nreem thiab sib npaug, thiab lub torque rated yuav tsum tau mus txog peb zaug.

3. Cov ntsia hlau txuas ntawm cov qhov kub siab yuav tsum tau nruj ob zaug hauv lub xeev kub.

V. Kev Tswj Xyuas Zoo

1. Yuav tsum tau kuaj lub zog thiab kuaj kev sib khi tom qab kev teeb tsa.

2. Thaum ntxuav lub kaw lus, lub qhov tswj hwm, lub ntsuas dej ntws thiab lwm yam khoom siv yuav tsum tau hla mus.

3. Sau cov ntaub ntawv teeb tsa, suav nrog cov ntaub ntawv tseem ceeb xws li tus lej qhov chaw ntawm lub valve, qhov siab sim, lub zog ua haujlwm, thiab lwm yam.

Lus Cim: Lub valve yuav tsum tsis txhob siv ua qhov chaw txhawb nqa rau cov kav dej. Cov valve loj xav tau ib lub thav duab txhawb nqa sib cais. Tom qab kev teeb tsa, lub valve yuav tsum nyob rau hauv qhov chaw kaw tag nrho thiab tiv thaiv kom tsis txhob muaj kev puas tsuaj hla kev ua haujlwm.
