Pneumatic film regulating valve pasi pemamiriro api anofanira kushandisa iyo valve positioner

Pneumatic film regulating valve pasi pemamiriro api anofanira kushandisa valve positioner Pneumatic film regulating valve inspection method: Tarisa kubuda kwekuvhara kwebhokisi rekutakura bhokisi nemamwe majoini Kupisa kwemvura pakupisa kwekamuri ndeye 1.1 nguva yezita rekumanikidzwa kwevhavha inogadzirisa kana 1.5 nguva iyo yakanyanya kushandiswa kushandiswa, maererano nekutungamira kwekuzarura spool mune imwe mugumo wevhavha inogadzirisa, imwe mugumo yakavharwa. Bata kudzvanywa kwemaminetsi gumi apo hunde inofamba 1-3 nguva paminiti. Panofanira kunge pasina kuvuza mukubatana kwekuvhara bhokisi rekutakura uye zvimwe zvikamu. 2 Tarisa uone kuvuza panguva yekuvharwa ① Kuburikidza kwekuongorora nzira yejekiseni remvura Kune maviri zvigaro zvinodzora vharafu zvinogona kushandiswa zviri nyore jekiseni remvura kutarisa mamiriro ekubuda. Input sign pressure mukamuri yefirimu gasi kuvhara vharuvhu inoronga (inopinza 1.2kg/cm2 chiratidzo chekumanikidza muvharuvhu yekuvhara gasi, uye gasi rakavhurika vharafu chiratidzo chekumanikidza i zero). Iyo inlet yevhavha yekudzora inojowa pane tembiricha yemvura, kana pasina kumanikidzwa kune imwe mugumo haifanirwe kunge iine dhip phenomenon. ② Tarisa kubuda kwemvura kudzvinyirirwa Iyi nzira inogona kushandiswa kuchekwa netsaona kana kuvhara yakasimba chigaro chinodzora vharafu, Angle inodzora vharafu uye diaphragm vharafu. Input signal pressure kune membrane chamber kuvhara regulator. Mvura iri pamhepo yekushisa inopfuudzwa kune imwe mugumo wevhavha inogadzirisa pamhepo inogara iine 10kg / cm2 munzira yekuzarura spool. Huwandu hwekuvuza hwakayerwa kune rumwe rutivi nestopwatch nekapu yekuyeresa haifanire kudarika kukosha kunobvumidzwa. Pneumatic film regulating valve pasi pemamiriro ezvinhu api anofanira kushandisa valve positioner 1. Apo chiratidzo chinobuda chemagetsi emagetsi chinoshandiswa kushandisa pneumatic actuator muchiitiko chekugadzirisa kwekomboni, inofanirwa kuva nekugadzirisa basa. Kana iyo inobuda chiratidzo chemagetsi regulator ichishandiswa kushandisa pneumatic actuator, inodiwa kuve nenzvimbo yekumisikidza panguva imwe chete, inogona kushandisa yemagetsi-gasi chinzvimbo 2, maviri chinzvimbo chiitiko mune yakaenzana chiitiko chekugadzirisa zviitiko hapana chitubu kana piston. actuator inzvimbo mbiri-chiito, kana ichidikanwa kuve neyakaenzanirana gadziriso, hapana chitubu kana piston actuator iri-mbiri-chinzvimbo chiito, kana ichidikanwa kuve nekuenzana gadziriso, inofanirwa kushandisa iyo valve chinzvimbo. A valve positioner inofanira kushandiswa. 3, nokuda kwechiitiko chepamusoro-soro musiyano pakati pemigumo miviri yevharuvhu 10kgf/cm yepakati pane spool unbalance force yakakura, apo △P> 10kgf/cm2, iyo yepakati pane spool unbalance force yakakura, nekuvandudza mhepo. sosi kudzvanywa kwepositioner kusvika kune actuator yekubuda simba, kukurira yepakati pane spool unbalance force. Mhepo ine simba remhepo inosvika pakubuda kwesimba re actuator kukunda simba risingaenzaniswi repakati pane spool. 4, kune yakanyanya kudzvanywa midhiya mune iyi kesi kuitira kudzivirira kupinda kwepakati, kurongedza kwakasimba kwazvo, kukakavara kwakakura, mune iyi kesi kuitira kudzivirira kupinda kwepakati, kurongedza kwakasimba kwazvo, iyo friction yakakura, panguva imwe chete, simba risina kuenzana repakati pane spool rakakura zvakare, chinodiwa chekuisa chigadziro chekukunda. Simba risina kuenzana rehuwandu pane spool yakakurawo, iyo inoda locator kuti ikunde.
