Lub sealing nto ntawm lub valve yog feem ntau corroded, eroded thiab hnav los ntawm nruab nrab, yog li nws yog ib feem ntawm lub valve uas yooj yim puas. Piv txwv li, qhov zoo ntawm qhov tsis siv neeg li qub xws li hluav taws xob pob li qub thiab hluav taws xob npauj npaim li qub cuam tshuam ncaj qha rau lub neej kev pab cuam ntawm lub valve vim yog qhib thiab kaw thiab qhib thiab kaw ceev ceev.
Lub hauv paus yuav tsum tau ntawm lub valve sealing nto yog tias lub valve tuaj yeem ua kom muaj kev ruaj ntseg thiab txhim khu kev qha sealing raws li kev ua haujlwm tau teev tseg, yog li:
Zoo sealing kev ua tau zoo
Ntawd yog, lub sealing nto yuav tsum muaj peev xwm tiv thaiv qhov to ntawm qhov nruab nrab zoo;
Muaj zog
Nyob rau hauv qhov kev txiav txim ntawm qhov nruab nrab siab sib txawv, lub sealing nto yuav tsum muaj peev xwm tiv taus lub sealing siab piv tus nqi tsim los ntawm nws:
Corrosion kuj
Nyob rau hauv lub sij hawm ntev ntawm corrosive media thiab kev ntxhov siab, lub sealing nto yuav tsum muaj ib tug muaj zog corrosion kuj uas yog sib xws nrog cov qauv tsim:
Muaj peev xwm tiv taus abrasion
Lub valve sealing khub yog lub foob dynamic, thiab muaj kev sib txhuam ntawm cov ntsaws ruaj ruaj thaum qhib thiab kaw cov txheej txheem:
Erosion kuj
Lub sealing nto yuav tsum muaj peev xwm tiv taus qhov yaig ntawm kev kub ceev xov xwm thiab kev cuam tshuam ntawm cov khoom siv:
