4, lub ntiaj teb valve: yog hais txog qhov kaw qhov chaw (disc) raws kab nruab nrab ntawm lub rooj zaum valve.Raws li daim ntawv txav ntawm lub disc, qhov kev hloov ntawm lub rooj zaum valve qhib yog ncaj qha proportional rau lub disc stroke.Vim li no lub valve qia qhib los yog kaw stroke yog luv luv, thiab muaj kev txhim khu kev qha heev txiav tawm muaj nuj nqi, thiab vim hais tias ntawm kev hloov ntawm lub valve lub rooj qhib thiab cov hlab ntsha ntawm lub disc yog ncaj qha proportional, heev haum rau kev khiav dej num.Yog li ntawd, hom valve no yog rhiab heev rau txiav los yog tswj thiab throttling.
Qhov zoo:
(1) Nyob rau hauv tus txheej txheem ntawm kev qhib thiab kaw, vim muaj kev sib txhuam ntawm lub disc thiab lub valve lub cev sealing nto yog me dua li lub rooj vag valve, yog li qhov hnav tsis kam.
② Qhov qhib qhov siab feem ntau tsuas yog 1/4 ntawm lub rooj zaum valve, ntau me dua li lub rooj vag valve;
(3) feem ntau tsuas muaj ib qho kev sib khi ntawm lub cev valve thiab disc, yog li cov txheej txheem tsim khoom zoo dua, yooj yim los tswj;
④ Raws li cov muab tub lim feem ntau yog sib xyaw ntawm asbestos thiab graphite, nws muaj qib kub tsis kam.General steam valve yog siv los ntawm lub ntiaj teb valve.
Qhov tsis zoo:
(1) Vim tias qhov ntws ntawm qhov nruab nrab los ntawm lub valve tau hloov pauv, yog li cov dej ntws me me ntawm lub ntiaj teb valve yog siab dua li lwm hom li qub;
② Vim lub stroke ntev, qhov qhib ceev yog qeeb dua pob valve.
