Hauv kev muaj tiag, hluav taws xob tswj valve tau siv dav hauv kev lag luam thiab tsuas. Lub pob hluav taws xob tswj lub pob valve feem ntau yog tsim los ntawm angular stroke hluav taws xob actuator thiab npauj npaim valve los ntawm kev sib txuas, tom qab kev teeb tsa thiab kev debugging. Hluav taws xob tswj lub pob valve raws li kev ua haujlwm hom kev faib tawm: hloov hom thiab kev tswj hom. Cov hauv qab no yog cov lus piav qhia ntxiv ntawm hluav taws xob tswj pob valve.
Muaj ob lub ntsiab lus tseem ceeb hauv kev teeb tsa hluav taws xob tswj lub pob valve
1) Kev teeb tsa txoj haujlwm, qhov siab thiab kev taw qhia ntawm qhov nkag thiab qhov hluav taws xob yuav tsum ua kom tau raws li cov qauv tsim. Cov kev taw qhia ntawm nruab nrab ntws yuav tsum ua raws li cov kev taw qhia ntawm xub cim rau ntawm lub valve lub cev, thiab kev sib txuas yuav tsum ruaj thiab nruj.
2) Ua ntej kev teeb tsa hluav taws xob tswj lub pob valve, yuav tsum tau ua qhov kev tshuaj xyuas zoo li qub, thiab lub npe lub npe phaj yuav tsum ua raws li lub teb chaws tus qauv tam sim no "phau ntawv valve cim" GB 12220. Rau lub valve nrog kev ua haujlwm siab tshaj 1.0 MPa thiab txiav tawm kev ua haujlwm ntawm cov yeeb nkab tseem ceeb, kev ntsuas lub zog thiab nruj yuav tsum tau ua ua ntej kev teeb tsa, thiab lub valve tsuas yog siv tau tom qab nws tsim nyog. Thaum lub sij hawm kuaj lub zog, qhov kev ntsuam xyuas siab yuav tsum yog 1.5 npaug ntawm lub nominal siab, lub sij hawm yuav tsum tsis txhob tsawg tshaj li 5min, thiab lub plhaub valve thiab packing yuav tsum tsim nyog yog tias tsis muaj to.
Raws li cov qauv, lub pob hluav taws xob tswj lub pob valve tuaj yeem muab faib ua phaj offset, ntsug phaj, inclined phaj thiab qib qib. Raws li daim ntawv sealing, nws tuaj yeem muab faib ua ob hom: hom kaw ntom ntom thiab nyuaj kaw hom. Hom foob mos yog feem ntau kaw nrog lub nplhaib roj hmab, thaum lub zog foob hom feem ntau yog kaw nrog lub nplhaib hlau.
Raws li hom kev sib txuas, lub tshuab hluav taws xob tswj lub pob valve tuaj yeem muab faib ua flange kev twb kev txuas thiab khub clamp txuas; Raws li hom kev sib kis, nws tuaj yeem muab faib ua phau ntawv, iav kis tau tus mob, pneumatic, hydraulic thiab hluav taws xob.
Installation thiab txij nkawm ntawm hluav taws xob tswj pob valve
1. Thaum lub sij hawm installation, lub disc yuav tsum nres ntawm qhov chaw kaw.
2. Txoj haujlwm qhib yuav tsum tau txiav txim siab raws li lub kaum sab xis ntawm lub pob.
3. Rau pob valve nrog bypass valve, lub bypass valve yuav tsum tau qhib ua ntej qhib.
4. Lub tshuab hluav taws xob tswj lub pob valve yuav tsum tau muab tso rau raws li cov lus qhia ntawm lub chaw tsim khoom, thiab lub pob valve hnyav yuav tsum muab lub hauv paus ruaj khov.
