Muzochitika zachilendo, ma valve a mafakitale sayesa kuyesa mphamvu pamene akugwiritsidwa ntchito, koma mutatha kukonza thupi la valve ndi chivundikiro cha valve kapena kuwonongeka kwa dzimbiri kwa thupi la valve ndi chivundikiro cha valve chiyenera kuyesa mphamvu. Kwa mavavu otetezera, kukakamiza kokhazikitsa ndi kubwereza kubwereza ndi mayeso ena amayenera kutsatira zomwe zafotokozedwa ndi malamulo oyenera. Valavu iyenera kuyesedwa kuti ikhale yamphamvu komanso yolimba musanayike. Mavavu apakati ndi apamwamba ayenera kuyang'aniridwa. Kuyesa kwa ma valve omwe amagwiritsidwa ntchito kwambiri ndi madzi, mafuta, mpweya, nthunzi, nayitrogeni, ndi zina zotero. Mitundu yonse ya mavavu a mafakitale kuphatikizapo njira zoyesera za pneumatic valves ndi monga:

1.Valve ya mpiranjira yoyesera kuthamanga

Mayeso amphamvu a valavu ya mpira wa pneumatic ayenera kuchitidwa mu gawo lotseguka la mpira.

(1)Mpira woyandamakuyesa kwa valve: valve ndi yotseguka, mapeto amodzi amalowetsedwa muzitsulo zoyesera, ndipo mapeto ena atsekedwa; Tembenuzani mpirawo kangapo, tsegulani mapeto otsekedwa pamene valavu yatsekedwa, ndipo yang'anani ntchito yosindikizira ya kunyamula ndi gasket, ndipo pasakhale kutayikira. Kenako yambitsani njira yoyesera kuchokera kumapeto ena ndikubwereza mayeso omwe ali pamwambapa.

(2)Bal yokhazikikal kuyesa kwa valve: musanayambe kuyesedwa, mpira umatembenuzidwa kangapo popanda katundu, ndipo valavu yokhazikika ya mpira imakhala yotsekedwa, ndipo sing'anga yoyesera imatengedwa kuchokera kumapeto mpaka ku mtengo wotchulidwa; Mpweya wopimitsira umagwiritsidwa ntchito poyang'ana momwe kusindikizira kolowera kumapeto. Kulondola kwa 0.5 ~ 1, ndipo miyeso yoyezera ndi nthawi 1.5 ya kuthamanga kwa mayeso. Mu nthawi yodziwika, palibe chodabwitsa cha depressurization chomwe chili choyenera; Kenako yambitsani njira yoyesera kuchokera kumapeto ena ndikubwereza mayeso omwe ali pamwambapa. Ndiye, valavu ndi theka lotseguka, mapeto onse atsekedwa, mkati mwa mkati mwadzaza ndi zofalitsa, ndipo kulongedza ndi gasket kumafufuzidwa pansi pa kukakamizidwa kwa mayeso popanda kutayikira.

(3)Valve yanjira zitatu sayenera kuyesedwa kulimba m'malo osiyanasiyana.

2.Onani valavunjira yoyesera kuthamanga

Yang'anani mawonekedwe a mayeso a vavu: kukweza mtundu wa valavu cheke chimbale axis ali yopingasa ndi ofukula malo; Mzere wa swing check valve channel ndi axis ya disc ndi pafupifupi kufanana ndi mzere wopingasa.

Panthawi yoyesera mphamvu, sing'anga yoyesera imayambitsidwa ku mtengo wotchulidwa kuchokera kumapeto kwa cholowera, mapeto ena amatsekedwa, ndipo thupi la valve ndi chivundikiro cha valve ndizoyenerera popanda kutaya.

Mayeso osindikizira awonetsa njira yoyesera kuchokera kumapeto, kuyang'ana malo osindikizira pamapeto olowera, ndipo kulongedza ndi gasket kumakhala koyenerera ngati palibe kutayikira.
