1. Musanakhazikitse, fufuzani kuti mbali zonse za valve butterfly sizikusowa, chitsanzocho ndi cholondola, palibe zinyalala m'thupi la valve, ndipo palibe kutsekeka mu valve solenoid ndi muffler.

2. IkaniMAVAVU A MPIRAndi silinda mu boma lotsekedwa.

3. Menyani silinda motsutsana ndi valavu (njira yoyikirayi imakhala yofanana kapena yozungulira ku thupi la valve), ndiyeno fufuzani ngati mabowo a screw akugwirizana, sipadzakhala kupatuka kwambiri.Ngati pali kupatuka pang'ono, ingotembenuzani thupi la silinda pang'ono., Kenako kumangitsa zomangira.

4. Pambuyo poika, sungani valavu ya butterfly (kuthamanga kwa mpweya ndi 0.4 ~ 0.6MPa pansi pazikhalidwe), ndipo valavu ya solenoid iyenera kutsegulidwa ndi kutsekedwa pamanja panthawi ya ntchito yowonongeka (ntchito yamanja ikhoza kukhala yothandiza pambuyo pa coil valve solenoid de-energized), ndi kuwona Kutsegula ndi kutseka kwa valavu ya butterfly ya pneumatic.Ngati valavu imapezeka kuti ndi yovuta kwambiri kumayambiriro kwa kutsegula ndi kutseka panthawi yokonza zolakwika, ndiyeno ndizozoloŵera, muyenera kuchepetsa kugunda kwa silinda (zomangira zosintha za stroke pamapeto onse a silinda. ziyenera kusinthidwa mkati nthawi yomweyo, ndipo valavu iyenera kusunthira kumalo otseguka panthawi yosintha.Tiyeneranso kukumbukira kuti silencer yosinthika imatha kusintha liwiro lotsegula ndi kutseka kwa valve, koma siliyenera kusinthidwa pang'ono, mwinamwake valavu silingagwire ntchito.

5. Defa ikhale yowuma isanakhazikitsidwe osati kusungidwa panja

6. Yang'anani payipi musanayike valavu ya butterfly kuti muwonetsetse kuti palibe zinthu zakunja monga kuwotcherera slag mupaipi.

7. Buku lotsegula ndi kutseka kukana kwa thupi la butterfly valve ndi lochepa, ndipo torque ya valavu ya butterfly imagwirizana ndi torque ya actuator yosankhidwa.

8. Mafotokozedwe a flange olumikizira ma valve a butterfly ndi olondola, ndipo chotchingira cha chitoliro chimagwirizana ndi muyezo wa gulugufe.Ndi bwino kugwiritsa ntchito flanges wapadera kwa mavavu gulugufe m'malo lathyathyathya kuwotcherera flanges.

9. Onetsetsani kuti kuwotcherera kwa flange ndikolondola.Vavu yagulugufe ikayikidwa, flange siyenera kuwotcherera kuti musawotche mbali za rabala.

10. Choyikapo chitolirocho chiyenera kukhala pakati ndi pakati ndi valavu ya butterfly.

11. Ikani ma bolt onse a flange ndikumangitsa ndi dzanja.Zidzatsimikiziridwa kuti valavu ya butterfly ndi flange yakhala ikugwirizana, ndiyeno valavu ya butterfly idzatsegulidwa ndi kutsekedwa mosamala kuti zitsimikizire kutseguka ndi kutseka kosavuta.

12. Tsegulani valavu kwathunthu.Gwiritsani ntchito wrench kuti mumangitse mabawuti motsatana.Palibe zochapira zomwe zimafunikira.Osawonjeza ma bolts kuti mupewe kusinthika kwakukulu kwa mphete ya valve komanso kutsegulira ndi kutseka kwambiri.
