Hluav taws xob actuator xaiv rau hluav taws xob npauj npaim li qub

Txij li thaum hluav taws xob npauj npaim valve yog tsim los ntawm npauj npaim valve thiab lub tshuab hluav taws xob, yuav ua li cas xaiv cov khoom siv hluav taws xob kom raug tom qab hluav taws xob npauj npaim valve tau txiav txim siab yog qhov tseem ceeb ntsig txog seb nws puas tuaj yeem ua tau raws li qhov xav tau ntawm engineering hauv kev siv tiag tiag. Thaum xaiv cov khoom siv hluav taws xob, tsis yog tsuas yog qhov chaw ua haujlwm tau hais tseg, kev tswj hluav taws xob thiab kev ua haujlwm dav dav yuav tsum raug txiav txim siab, tab sis kuj tseem yuav tsum tau xav txog qhov kev ua tau zoo ntawm cov hluav taws xob npauj npaim valve ntaus ntawv yuav tsum tau txiav txim siab tag nrho.

1. Tso cai tus nqi ntawm valve qia txoj kab uas hla

Thaum xaiv cov khoom siv hluav taws xob rau lub lifting qws valve, yuav tsum tau them nyiaj mloog mus rau txoj kab uas hla ntawm lub valve qia uas tso cai rau hla, thiab txoj kab uas hla ntawm lub valve qia yuav tsum me dua li tus nqi no. Tsis tas li ntawd, rau ntau-tig hluav taws xob, cov kev xav tau rau qhov siab ntawm lub valve qia npog yuav tsum tau muab tso rau pem hauv ntej thaum xaiv lawv (txog rau lub valve qhov siab). Rotary qia li qub yog muaj yam tsis muaj qia npog.

2. Kev sib txuas ntawm lub valve thiab cov khoom siv hluav taws xob
Hom kev sib txuas thiab qhov loj ntawm lub valve thiab lub tshuab hluav taws xob yuav tsum ua raws li lub teb chaws tus qauv: GB / T12222-1989 Kev sib txuas ntawm ntau-tig valve tsav tsheb, GB / T12223-1989 Kev sib txuas ntawm ib nrab-tig valve tsav tsheb.

3. Tso zis torque thiab ceev ntawm hluav taws xob ntaus ntawv
Tus nqi torque tso zis yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, thiab nws tseem yog qhov tseem ceeb uas yuav tsum tau xaiv thaum siv. Yog hais tias qhov tso zis torque ntawm cov khoom siv hluav taws xob xaiv thaum sib sau ua ke hluav taws xob npauj npaim valve loj dhau lossis tsis txaus, nws tsis pom zoo. Vim hais tias feem ntau, cov cuab yeej hluav taws xob tsim hluav taws xob yuav tsum tau sim thiab kho qhov tso zis torque tus nqi ua ntej cov khoom tawm hauv lub Hoobkas, uas yog qhov tseeb. Yog tias xaiv qhov tso zis ntau dhau torque margin, lub valve hluav taws xob yuav ua rau muaj kev phom sij. Thaum tswj thiab tiv thaiv tsis ua hauj lwm tshwm sim, nws yuav yooj yim ua rau valve puas (valve qia dabtsi yog khoov, valve lub cev rupture), thiab yooj yim ua rau pipeline system xwm txheej. Yog li ntawd, nws tsis pom zoo kom xaiv qhov tso zis torque margin uas loj dhau. Yog tias lub valve tsis tuaj yeem qhib hauv kev ua haujlwm tiag tiag, nws yog qhov kev xaiv tsis tsim nyog.
