Lub disc lub khob hliav qab yog positioned tangentially, ib nrab ntawm lub disc thiab ib nrab ntawm lub ncej, ua rau nws nyob rau hauv compression es shear, uas tshem tawm qhov ua tsis tau tejyam.
Tus choj rocker-shaped caj pas them nyiaj rau qhov tsis sib xws ntawm cov noob txiv ntoo thiab txo cov ntim ntim.
Integral cam khwb cia disc txoj hauj lwm nres zoo kawg nkaus tso lub disc nyob rau hauv lub rooj zaum rau siab tshaj plaws lub rooj thiab foob lub neej.
Ob chav eccentric configuration, txhim khu kev qha sealing kev ua tau zoo, xyuas kom meej tias lub valve disc yuav tsis hu rau lub sealing lub rooj thaum pib, daws qhov teeb meem ntawm uneven load ntawm lub sealing lub rooj, prolongs lub neej kev pab cuam, thiab muaj qhov zoo ntawm kub tsis kam, hnav tsis kam, corrosion kuj, thiab lwm yam., kom ntseeg tau tias sealing kev ua tau zoo.
Me me, lub teeb yuag, yooj yim installation thiab txij nkawm.
Ob chav eccentric npauj npaim valve tseem hu ua kev ua haujlwm siab npauj npaim valve. Nws yog tsuas yog siv rau kev tso dej ntawm cov nroj tsuag dej, cov nroj tsuag hluav taws xob, cov nroj tsuag hlau thiab hlau, tshuaj lom neeg, cov dej hauv dej, kev tsim kho ib puag ncig, thiab lwm yam. Nws yog tshwj xeeb tshaj yog tsim rau cov kav dej hauv cov kav dej raws li kev hloov kho thiab txiav cov cuab yeej.
Piv nrog rau lub centerline npauj npaim valve, ob chav eccentric npauj npaim valve yog ntau resistant rau kev kub siab, muaj lub neej ntev thiab zoo stability. Piv nrog rau lwm cov li qub, qhov loj ntawm txoj kab uas hla, qhov sib zog ntawm cov khoom siv thiab tus nqi qis dua. Tab sis vim hais tias muaj ib lub phaj npauj npaim nyob nruab nrab, qhov kev khiav hauj lwm yog qhov loj, yog li tus npauj npaim valve me dua DN200 yog qhov tseem ceeb me ntsis.
