hluav taws xob triple -eccentric npauj npaim valveQauv:
Txoj Cai Eccentricity
Thawj Eccentricity: Lub valve ncej yog offset los ntawm nruab nrab ntawm lub phaj npauj npaim, txo kev sib txhuam ntawm tus npauj npaim phaj thiab lub rooj zaum valve thaum qhib thiab kaw.
Thib ob Eccentricity: Lub valve ncej yog offset los ntawm qhov chaw ntawm lub valve lub cev sealing nto, ua tiav sai disengagement thaum qhib thiab kaw.
Thib peb Eccentricity: Lub valve lub rooj sealing nto yog tilted ntawm ib lub kaum ntse ntse (conical eccentricity), kom ntseeg tau ib txoj kab sib khi ntawm tus npauj npaim phaj thiab lub rooj zaum valve, tsim cov hlau - mus rau -hlau hard seal qauv.
Peb-Dimensional Eccentricity Effects: Los ntawm lub valve qia axis offset, valve lub cev channel axis offset, thiab eccentricity lub kaum sab xis tsim, xoom-kev sib txhuam ntawm lub sealing nto tiav, tshem tawm cov khoom siv thiab khawb thaum qhib thiab kaw.
