Vavu yowongolera filimu ya pneumatic pazifukwa zomwe muyenera kugwiritsa ntchito choyimira valavu

Valavu yoyang'anira filimu ya pneumatic pazifukwa zomwe ziyenera kugwiritsira ntchito valve positioner Pneumatic film regulating valve inspection: Yang'anani kutuluka kwa bokosi losindikizira ndi ziwalo zina Kutentha kwa madzi pa kutentha kwa chipinda ndi nthawi 1.1 kukakamiza mwadzina kwa valve yoyendetsera kapena nthawi 1.5 Kuthamanga kwakukulu kogwiritsira ntchito, molingana ndi malangizo a kutsegula spool kumapeto kwa valve yolamulira, mapeto ena amatsekedwa. Gwirani kuthamanga kwa mphindi 10 pamene tsinde likuyenda 1-3 pa mphindi. Sipayenera kukhala kutayikira mu kugwirizana kusindikiza kunyamula bokosi ndi zigawo zina. 2 Yang'anani kutayikira potseka ① Kuyang'anira kutayikira kwa njira ya jakisoni wamadzi Pamipando iwiri yowongolera valavu ingagwiritsidwe ntchito munjira yosavuta ya jakisoni wamadzi kuti muwone komwe kutayikira. Lowetsani mphamvu ya siginecha muchipinda cha mpweya wa filimu kuti mutseke valavu yowongolera (kulowetsani 1.2kg/cm2 kukakamiza kwa siginecha mu valavu yotsekera gasi, ndipo mphamvu yamagetsi yotseguka ya gasi ndi ziro). Kulowera kwa valavu yoyang'anira kumalowetsedwa m'madzi otentha otentha, ngati palibe kupanikizika pamapeto ena sayenera kukhala chodabwitsa. ② Yang'anani kutayikira kwa kuthamanga kwa madzi Njirayi ingagwiritsidwe ntchito podula mwangozi kapena kutseka mwamphamvu pampando umodzi wowongolera valavu, valavu yowongolera ma angle ndi valavu ya diaphragm. Lowetsani kukakamiza kwa siginecha kuchipinda cha membrane kuti mutseke chowongolera. Madzi otentha kutentha amadutsa kumapeto kwa valve yoyendetsa nthawi zonse pa 10kg / cm2 kuti atsegule spool. Kuchulukira kwachulukidwe komwe kuyezedwa kumapeto kwina ndi choyimira ndi kapu yoyezera sikuyenera kupitilira mtengo wololeka. Valavu yoyang'anira filimu ya pneumatic pansi pazimene ziyenera kugwiritsira ntchito valve positioner 1. Pamene chizindikiro chotulutsa chowongolera magetsi chimagwiritsidwa ntchito pogwiritsira ntchito makina oyendetsa pneumatic mu nthawi ya malamulo a pawiri, amayenera kukhala ndi ntchito yoyika. Pamene chizindikiro chotuluka cha chowongolera magetsi chikugwiritsidwa ntchito poyendetsa pneumatic actuator, chimafunika kuti chikhale ndi malo nthawi yomweyo, chimatha kugwiritsa ntchito choyimira chamagetsi chamagetsi 2, malo awiri ochitapo kanthu muzochitika zosinthika popanda masika kapena pistoni. actuator ndi magawo awiri, pakafunika kusintha kofananira, palibe kasupe kapena piston actuator yomwe ili ndi magawo awiri, ikafunika kusinthidwa molingana, iyenera kugwiritsa ntchito choyimira valavu. Choyimira cha valve chiyenera kugwiritsidwa ntchito. 3, chifukwa cha kusiyana kwakukulu pakati pa malekezero awiri a valve 10kgf/cm sing'anga pa spool mphamvu yosalinganika ndi yaikulu, pamene △P> 10kgf/cm2, sing'anga pa spool mphamvu yosagwirizana ndi yaikulu, mwa kukonza mpweya. gwero la kukakamiza kwa poyimitsa kuti ifike ku mphamvu ya actuator, kugonjetsa sing'anga pa mphamvu ya spool yosagwirizana. Kuthamanga kwa gwero la mpweya kumafika ku mphamvu yotulutsa mphamvu ya actuator kuti igonjetse mphamvu yosayenerera ya sing'anga pa spool. 4, kwa media media pankhani iyi kuti mupewe kulowa kwa sing'anga, kulongedza kumakhala kolimba kwambiri, kukangana kumakhala kokulirapo, pakadali pano pofuna kupewa kulowa kwa sing'anga, kulongedza kumakhala kolimba kwambiri, kukangana ndi kokulirapo, panthawi imodzimodziyo, mphamvu yosagwirizana ya sing'anga pa spool imakhalanso yokulirapo, kufunikira kwa chipangizo choyikirapo kuti chigonjetse. Mphamvu yosagwirizana ya misa pa spool imakhalanso yaikulu, yomwe imafuna locator kuti agonjetse.
