Valve yachipata ndi valavu ya butterflyzonse zimagwira ntchito yosintha ndi kuwongolera kayendedwe ka kayendedwe ka mapaipi.Zoonadi, pali njira zopangira ma valve a butterfly ndi ma valve a zipata.
Mumaukonde operekera madzi, pofuna kuchepetsa kuya kwa dothi la payipi, nthawi zambiri mipope yokulirapo imakhala ndivalavu butterfly, zomwe zimakhala ndi zotsatira zochepa pa kuya kwa nthaka yophimba, ndipo yesetsani kusankha ma valve a zipata, koma mtengo wa ma valve a chipata chofanana ndi wapamwamba kuposa wa agulugufe.Ponena za mzere wolekanitsa wa caliber, uyenera kuganiziridwa pazochitika ndi zochitika.Malinga ndi momwe mavavu amagwirira ntchito m'zaka khumi zapitazi, kulephera kwa ma valve agulugufe ndikwambiri kuposa mavavu a pachipata, chifukwa chake ndikofunikira kukulitsa kuchuluka kwa kugwiritsa ntchito mavavu a pachipata ngati mikhalidwe ikuloleza.
Za ma valve pachipata M'zaka zaposachedwa, opanga ma valve ambiri apakhomo apangamavavu a zipata zofewa.Poyerekeza ndi mavavu achipata amtundu wa wedge kapena ofanana, ma valve a pachipata ichi ali ndi izi:
* Thupi la valve ndi bonnet la valve yotsekedwa ndi chipata chofewa amaponyedwa ndi njira yolondola yoponyera, yomwe imapangidwa nthawi imodzi, makamaka popanda makina opangira makina, ndipo sagwiritsa ntchito mphete yamkuwa yosindikiza, yomwe imasunga zitsulo zopanda chitsulo.
* Palibe dzenje pansi pa valve yotsekedwa yotsekedwa, ndipo palibe slag yomwe imasonkhanitsidwa, ndipo kulephera kwa chitseko cha valve kutsegula ndi kutseka kumakhala kochepa.
* Chisindikizo chofewa chokhala ndi mphira chokhala ndi mphira chimakhala ndi kukula kofanana ndi kusinthasintha kwamphamvu.
Chifukwa chake, avalavu yotseka pachipata chofewaidzakhala mawonekedwe omwe makampani opanga madzi akulolera kutengera.Pakali pano, m'mimba mwake wa mavavu ofewa osindikizidwa pachipata opangidwa ku China ndi mpaka 1500mm, koma awiri opanga ambiri ndi pakati 80-300mm.Gawo lofunika kwambiri la valve yotsekemera yotsekemera ndi mbale ya mphira yokhala ndi mphira, ndipo zofunikira zaumisiri wa mbale ya valve yokhala ndi mphira ndizokwera kwambiri, zomwe si onse opanga akunja omwe angathe kuzikwaniritsa, ndipo nthawi zambiri amagulidwa ndikusonkhanitsidwa kuchokera kwa opanga odalirika. khalidwe.
Chotchinga chamkuwa cha valavu yotsekera pachipata chofewa chimayikidwa pamwamba pa mbale ya valve yokhala ndi mphira, yomwe ili yofanana ndi kapangidwe ka valavu yachipata.Chifukwa cha kugwedezeka kwa nati, mphira wa mbale ya valve imasenda mosavuta.Muzitsulo zofewa zosindikizira zipata za kampani yakunja, chipika cha mtedza wamkuwa chimayikidwa mu chipata chokhala ndi mphira kuti chikhale chonse, chomwe chimagonjetsa zofooka zomwe zili pamwambazi, koma kukhazikika kwa kuphatikiza kwa bonnet ndi thupi la valve ndilokwera kwambiri. .
Komabe, potsegula ndi kutsekavalavu yotseka pachipata chofewa, sayenera kutsekedwa kwambiri, malinga ngati mphamvu yoyimitsa madzi ikupezeka, mwinamwake sikophweka kutsegula kapena mphira wa rabara umachotsedwa.Wopanga ma valve amagwiritsa ntchito wrench ya torque kuwongolera kuchuluka kwa kutseka pakuyesa kukakamiza kwa valve.Monga woyendetsa valve wa kampani yamadzi, njira iyi yotsegulira ndi yotseka iyeneranso kutsanziridwa.
