HWV 101-125
Lub flange ntiaj teb valve yog ib hom valve nrog ib feem kaw (valve flap) uas txav raws li lub rooj zaum nruab nrab ntawm lub valve. Raws li lub valve nrov plig plawg txav, kev hloov ntawm lub rooj zaum qhov chaw nres nkoj yog proportional rau lub valve nrov plig plawg stroke.
Lub stroke ntawm kaw los yog qhib flange qia ntawm no valve yog piv luv luv thiab nws muaj ib tug txhim khu kev qha txiav-tawm muaj nuj nqi, hloov lub rooj zaum chaw nres nkoj cuam tshuam rau lub flap stroke proportionately uas ua rau lub ntiaj teb valve haum rau cov dej ntws tswj. Yog li ntawd, flange ntiaj teb li qub yog zoo tagnrho rau kev tswj los yog kaw-tawm thiab throttling flow daim ntaub ntawv.
Cov ntau yam tuaj yeem tsim kho kom haum rau koj daim ntawv thov, nrog rau kev tsim kho lub cev, cov khoom siv, thiab cov yam ntxwv ntxiv tau ua kom tau raws li koj cov kev xav tau. Raws li ISO 9001 tau ntawv pov thawj, peb txais yuav txoj hauv kev los xyuas kom meej qhov zoo, koj tuaj yeem paub tseeb ntawm kev ntseeg tau zoo thiab kev sib khi ua tau zoo los ntawm kev tsim lub neej ntawm koj lub cuab tam.
