Ndi mavuto ati omwe amabwera ndi ma valve a butterfly pakugwiritsa ntchito?
Vavu ya butterfly chifukwa cha kukula kwake kakang'ono ndi kapangidwe kosavuta, yakhala imodzi mwa mavavu omwe amagwiritsidwa ntchito kwambiri m'makampani, ndipo amagwiritsidwa ntchito kwambiri pamagetsi opangira madzi, ulimi wothirira, kumanga madzi ndi ngalande, zomangamanga zamatauni ndi machitidwe ena a mapaipi, omwe amagwiritsidwa ntchito popanga magetsi. kudula kapena kuyimira pakati pamayendedwe ozungulira media kuti mugwiritse ntchito.Ndiye valavu gulugufe ntchito mavuto amene akufunika chisamaliro ndi njira zothetsera zimene, lero tidzakhala mwachindunji kumvetsa.
Kuyika ma valve a butterfly ndikofunikira:
1.Musanakhazikitse, chonde tsimikizirani kuti ntchito ya malonda ndi mivi yothamanga ikugwirizana ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. kutsukidwa pamaso palibe kuloledwa kutseka gulugufe mbale, kuti kuwononga kusindikiza mphete.
2.Disc mbale unsembe kuthandiza flange tikulimbikitsidwa kugwiritsa ntchito flange gulugufe valavu wapadera.
3.Kuyika pakati pa payipi kapena malo a malekezero awiri a payipi, malo abwino kwambiri opangira vertical installation, sangathe kuikidwa mozondoka.
4. Kugwiritsa ntchito kufunikira koyendetsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
5. Tsegulani ndi kutseka zambiri valavu gulugufe, pafupifupi miyezi iwiri, ayenera kutsegula nyongolotsi zida bokosi chivundikirocho, fufuzani ngati batala ndi wabwinobwino, ayenera kusunga kuchuluka kwa batala.
6.Fufuzani ngati zigawo zogwirizanitsa zikuphwanyidwa, ndiko kuti, kutsimikizira kusindikizidwa kwa kunyamula, komanso kuonetsetsa kuti kuzungulira kwa tsinde la valve kumasinthasintha.
7.Metal seal butterfly valves si oyenera kuyika kumapeto kwa payipi, monga momwe ziyenera kuyikidwira kumapeto kwa payipi, muyenera kutenga flange yotsekera, kuti mupewe kusindikiza kwa mphete yosindikizira, udindo.
8.Kuyika tsinde la valve ndi kugwiritsa ntchito yankho kuti ayang'ane nthawi zonse momwe ma valve akuyendera, anapeza zolakwika panthawi yake.
Zomwe zimayambitsa kulephera: kusindikiza kutayikira pamwamba
1.Valve mbale, kusindikiza pamwamba chikwatu zinyalala
2.Valve mbale, kusindikiza pamwamba kutseka malo kumagwirizana ndi zolakwika
3.Outlet mbali kasinthidwe kukwera flange mabawuti mphamvu osafanana kapena mabawuti lotayirira
4.Kuwongolera koyeserera sikuli molingana ndi zofunikira zamayendedwe apakati.
Njira zochotsera
1.Chotsani zonyansa, yeretsani mkati mwa valve
2.Sinthani zida za nyongolotsi kapena magetsi, zomangira za pneumatic actuator kuti mukwaniritse malo oyenera a kutsekedwa kwa valve.
3.Kuyang'ana ndege ya flange yopangidwa ndi bolt compression fastening, iyenera kuphwanyidwa mofanana
4.Malinga ndi njira yosindikizira muvi kuti ipanikizike
Vavu ziwiri malekezero kutayikira kulephera zimayambitsa
1.Both mbali za kusindikiza gasket kulephera
2.Pipe flange tightness si yunifolomu kapena wosakanizidwa
3.Kusindikiza mphete kapena mphete yosindikizira mu kulephera kwa gasket
Njira yothetsera
1.Bwezerani gasket yosindikiza
2.Pressure flange bolts (yunifolomu mphamvu)
3.chotsani mphete ya valve, sinthani mphete yosindikizira ndi kulephera kwa gasket.
Vavu yagulugufe imatha kugawidwa pakati pa gulugufe valavu ndi eccentric butterfly valavu malinga ndi mawonekedwe ake.Malinga ndi mawonekedwe osindikizira akhoza kugawidwa mu mtundu wofewa wosindikizira ndi mtundu wa chisindikizo cholimba.Mtundu wofewa wosindikiza nthawi zambiri umagwiritsa ntchito mpando wa valavu ya rabara kapena kusindikiza mphete za mphira, mtundu wosindikiza wolimba nthawi zambiri umagwiritsa ntchito kusindikiza mphete zachitsulo.Malingana ndi mtundu wa kugwirizana, zikhoza kugawidwa mu kugwirizana kwa flange ndi kugwirizana kwa wafer;malinga ndi njira yotumizira, imatha kugawidwa m'mabuku, magetsi, pneumatic ndi hydraulic.Titha kusankha ma actuators osiyanasiyana malinga ndi momwe amagwirira ntchito.
