Ob chav eccentric nyuaj foob npauj npaim valveyog maj mam txhim kho los ntawm qhov zoo tib yam npauj npaim valve kom hloov mus rau cov kev ua haujlwm sib txawv (xws li kev ua haujlwm kub thiab kev ua haujlwm siab).Nws muaj qhov zoo ntawm cov qauv yooj yim, txhim khu kev qha sealing, lub teeb qhib, lub neej ua haujlwm ntev thiab kev saib xyuas yooj yim.Tam sim no, nrog rau kev loj hlob ntawm kev hloov pauv loj ntawm cov khoom siv hluav taws xob hluav taws xob hauv Suav teb, ob chav eccentric nyuaj foob npauj npaim valve tau siv dav hauv cov khoom siv dej thiab cov kav dej, lub tsev tiv thaiv hluav taws, metallurgy thiab lwm cov kav dej.
Txoj Cai Ua Haujlwm:
Hauv txoj kev xav, qhov zoo tib yam npauj npaim valve yog kaw raws li kab sib cuag.Thaum rau ntau theemob chav eccentric hlau nyuaj foob npauj npaim valve, txoj hauj lwm ntawm lub sealing khub tsim ib lub nplhaib dav siv los ntawm cov thawj linear vim qhov thib ob eccentricity (txoj hauj lwm ntawm lub valve qia txav).Ntev npaum li qhov kev sib cuag ntawm lub sealing khub yog nyob rau hauv lub nplhaib txoj siv, lub sealing yuav pom tau hais tias tsis muaj ib pab pawg neeg clamping thaum lub valve disc qhib.
Thaum lub sij hawm qhib lub valve disc, lub sealing cov ntsiab lus ntawm lub zoo tib yam npauj npaim valve disc txav raws lub tangent trajectory ntawm lub conical valve lub rooj tsav tsheb.Thiab muaj ib tug txheeb ze txhais lus ntawm lub sealing khub.Yog li qhov kev sib txhuam torque loj.Txawm li cas los xij, kev txhais lus ntawm kev sib khi khub ntawm lubob chav eccentric hlau nyuaj foob npauj npaim valveme me heev.Thiab txhua lub ntsiab lus ntawm qhov chaw sib txuas yog sib cais sai sai raws li tangent trajectory kev taw qhia ntawm conical valve lub rooj zaum tsheb npav.Yog li ntawd, kev sib txhuam torque yog me me, uas zoo txo qhov hnav ntawm cov khub sealing.
Nyob rau hauv lub metallurgy system, ob chav eccentric nyuaj foob npauj npaim valve yog tsuas yog siv nyob rau hauv lub preheating system thiab qhuav plua plav tshem tawm system ntawm ironmaking moj tej tawg rauv nrog loj nominal txoj kab uas hla, tsis tshua muaj ua hauj lwm siab, tsis tshua muaj qhib & kaw qhov sib txawv siab thiab kub (200 ° C. 350 ° C).
Raws li covob chav eccentric nyuaj foob npauj npaim valvemuaj kev sib khi zoo heev, siv dav dav, ua haujlwm siab, hnav tsis kam, corrosion kuj thiab lub neej ua haujlwm ntev.Yog li ntawd, nws lub luag hauj lwm yog raws li combustion cua kaw-off valve, combustion gas kaw-off valve, roj inlet & qhov hluav taws xob kaw-off valve ntawm tshav kub exchanger system, flue gas inlet & qhov hluav taws xob kaw valve ntawm tshav kub exchanger system thiab roj kaw. -off valve ntawm qhuav plua plav tshem tawm system.
