Emerson qhia txog SIL 3-certified valve assemblies

Emerson tau qhia txog thawj lub rooj sib dhos valve uas ua tau raws li cov qauv tsim ntawm Safety Integrity Level (SIL) 3 raws li International Electrotechnical Commission's IEC 61508 tus qauv. Cov Fisher noKev Cais Tawm DigitalCov kev daws teeb meem kawg ua haujlwm rau cov kev xav tau ntawm cov neeg siv khoom rau cov qhov kaw hauv cov ntawv thov kev nyab xeeb tseem ceeb (SIS).

Yog tsis muaj qhov kev daws teeb meem no, cov neeg siv yuav tsum teev tag nrho cov khoom siv ntawm lub valve, nrhiav txhua yam, thiab sib sau ua ke ua ib qho khoom siv. Txawm tias cov kauj ruam no ua tiav kom raug, hom kev sib dhos ua ke no tseem yuav tsis muab tag nrho cov txiaj ntsig ntawm Digital Isolation assembly.

Kev tsim lub valve kaw kev nyab xeeb yog ib txoj haujlwm nyuaj. Cov xwm txheej ib txwm muaj thiab cov txheej txheem tsis zoo yuav tsum tau soj ntsuam thiab nkag siab zoo thaum xaiv cov khoom siv valve thiab actuator. Tsis tas li ntawd, kev sib xyaw ua ke ntawm solenoids, brackets, couplings thiab lwm yam khoom siv tseem ceeb yuav tsum tau teev tseg thiab ua tib zoo phim rau lub valve xaiv. Txhua yam ntawm cov khoom no yuav tsum ua haujlwm ib leeg thiab ua ke kom ua haujlwm tau zoo.

Emerson daws cov teeb meem no thiab lwm yam teeb meem los ntawm kev muab lub rooj sib dhos kaw Digital Isolation, tsim los rau txhua txoj haujlwm tshwj xeeb. Cov khoom sib txawv tau xaiv tshwj xeeb kom ua tau raws li cov kev cai ntawm daim ntawv thov. Tag nrho cov khoom sib dhos tau muag ua ib qho khoom kuaj thiab tau ntawv pov thawj tag nrho, nrog rau ib tus lej serial thiab cov ntaub ntawv cuam tshuam uas piav qhia txog cov ntsiab lus ntawm txhua qhov ntawm kev sib dhos.

Vim tias qhov kev sib dhos no tau tsim los ua ib qho kev daws teeb meem tiav hauv Emerson cov chaw, nws muaj qhov ua tau zoo dua ntawm qhov ua tsis tiav raws li qhov xav tau (PFD). Qee zaum, qhov ua tsis tiav ntawm kev sib dhos yuav tsawg dua 50% piv rau kev sib xyaw ua ke ntawm cov khoom siv valve tib yam uas yuav ib leeg thiab sib dhos los ntawm tus neeg siv kawg.
