Qhov tseeb, lub tshuab hluav taws xob tswj tau siv dav hauv kev lag luam thiab kev tsuas. Lub pob hluav taws xob tswj feem ntau yog tsim los ntawm lub kaum sab xis hluav taws xob actuator thiab npauj npaim valve los ntawm kev sib txuas tshuab, tom qab kev teeb tsa thiab kev debugging. Lub pob hluav taws xob tswj raws li hom kev ua haujlwm faib tawm: hom hloov thiab hom kev tswj hwm. Cov hauv qab no yog cov lus piav qhia ntxiv ntawm lub pob hluav taws xob tswj.
Muaj ob lub ntsiab lus tseem ceeb hauv kev teeb tsa lub pob hluav taws xob tswj hwm
1) Qhov chaw teeb tsa, qhov siab thiab kev taw qhia ntawm qhov nkag thiab qhov tawm yuav tsum ua tau raws li qhov yuav tsum tau tsim. Kev taw qhia ntawm qhov nruab nrab ntws yuav tsum sib xws nrog kev taw qhia ntawm tus xub cim rau ntawm lub cev valve, thiab kev sib txuas yuav tsum ruaj khov thiab nruj.
2) Ua ntej kev teeb tsa lub pob hluav taws xob tswj lub pob valve, yuav tsum tau kuaj xyuas qhov tsos, thiab lub npe ntawm lub valve yuav tsum ua raws li tus qauv tam sim no ntawm lub tebchaws "phau ntawv qhia valve" GB 12220. Rau lub valve uas muaj lub zog ua haujlwm ntau dua 1.0 MPa thiab kev txiav tawm ntawm cov yeeb nkab tseem ceeb, yuav tsum ua qhov kev sim lub zog thiab kev nruj ua ntej kev teeb tsa, thiab lub valve tsuas yog siv tau tom qab nws tau tsim nyog. Thaum lub sijhawm sim lub zog, qhov kev sim siab yuav tsum yog 1.5 npaug ntawm qhov siab nominal, lub sijhawm yuav tsum tsis pub tsawg dua 5 feeb, thiab lub plhaub valve thiab cov khoom ntim yuav tsum tsim nyog yog tias tsis muaj qhov xau.
Raws li cov qauv, lub pob valve hluav taws xob tuaj yeem muab faib ua hom offset, hom ntsug, hom inclined thiab hom lever. Raws li daim ntawv sealing, nws tuaj yeem muab faib ua ob hom: hom kaw ruaj khov thiab hom kaw ruaj khov. Hom kaw mos feem ntau yog kaw nrog lub nplhaib roj hmab, thaum hom kaw ruaj khov feem ntau yog kaw nrog lub nplhaib hlau.
Raws li hom kev sib txuas, lub pob tswj hluav taws xob tuaj yeem muab faib ua kev sib txuas flange thiab kev sib txuas khub clamp; raws li hom kev sib kis, nws tuaj yeem muab faib ua phau ntawv, iav kis, pneumatic, hydraulic thiab hluav taws xob.
Kev teeb tsa thiab kev saib xyuas ntawm lub pob hluav taws xob tswj lub pob valve
1. Thaum lub sijhawm teeb tsa, lub disc yuav tsum nres ntawm qhov chaw kaw.
2. Qhov chaw qhib yuav tsum txiav txim siab raws li lub kaum sab xis ntawm lub pob.
3. Rau lub pob valve nrog bypass valve, lub bypass valve yuav tsum tau qhib ua ntej qhib.
4. Lub pob hluav taws xob tswj lub pob valve yuav tsum tau teeb tsa raws li cov lus qhia teeb tsa ntawm tus neeg tsim khoom, thiab lub pob valve hnyav yuav tsum tau muab nrog lub hauv paus ruaj khov.
