Kuyika Vavu Mpira:
1. Ziyenera kutsimikiziridwa kuti mapaipi ndi ma valve atsukidwa asanayambe ntchito.
2. Kugwira ntchito kwa valve ya valve kumayendetsa tsinde kuti izungulira molingana ndi kukula kwa chizindikiro cholowera. Vavu ikazungulira 1/4 nthawi (900) kutsogolo, valavu imatseka. Pamene kuzungulira kwa 1/4 (900), valve imatsegulidwa.
3. Pamene mayendedwe a actuator akuwonetsa kuti muvi ukufanana ndi payipi, valavu imatsegula; pamene muvi uli perpendicular kwa payipi, valavu kutseka.
Kusamalira Vavu Mpira:
Moyo wautali wautumiki ndi nthawi yopanda kukonza zidzadalira zinthu zingapo: kusunga kutentha kogwirizana / kupanikizika pansi pa ntchito yabwino, ndi deta yokwanira ya dzimbiri.
Zindikirani: Vavu ya mpira ikatsekedwa, kuthamanga kwamadzi mu thupi la valve kumakhalabe.
Musanakonze, chotsani kuthamanga kwa mzere ndikusunga valavu pamalo otseguka
Pamaso kukonza, kusagwirizana mphamvu kapena gasi gwero
Alekanitse cholumikizira ku bulaketi musanakonze
1. Kutsekera kutseka
Ngati culvert yodzaza ndi yotayirira pang'ono, mtedza wa tsinde uyenera kutsekedwa.
Zindikirani: Osatseka, nthawi zambiri kutseka 1/4 mphete ku mphete imodzi, kutayikira kumayima.
2. Kusintha Mipando ndi Zisindikizo
A. Disassembly
Siyani valavu pamalo otseguka ndipo tsitsani zinthu zoopsa zomwe zingakhalepo mkati ndi kunja kwa valve.
Tsekani valavu ya mpira, chotsani mabawuti ndi mtedza wa flanges mbali zonse, ndikuchotsa valavu kwathunthu papaipi.
Phatikizani chipangizo choyendetsera motsatizana - chowongolera, cholumikizira, chotsuka chotchinga, tsinde, kasupe wa butterfly, Gnan, mbale yosamva kuvala, kunyamula tsinde.
Chotsani thupi chivundikiro cholumikiza mabawuti ndi mtedza, kulekanitsa chivundikirocho ndi thupi, ndi kuchotsa chivundikiro gasket.
Tsimikizirani kuti mpirawo uli pamalo "ochoka", zomwe zimapangitsa kuti zikhale zosavuta kuzichotsa m'thupi ndikuchotsa mpando.
Tsinde limakankhidwira pansi kudzera mu dzenje la valavu mpaka litachotsedwa, ndiyeno mphete ya O-ring ndi kunyamula zimachotsedwa.
Chidziwitso: Chonde gwirani ntchito mosamala kuti mupewe kukanda pamwamba pa tsinde ndi kuyika chisindikizo cha valve.
B. Kukonzanso
Yeretsani ndi kuyang'ana mbali zomwe zawunikiridwa. M'malo mwa mpando ndi chivundikiro gaskets ndi zosindikizira ndi zida zosinthira phukusi akulimbikitsidwa kwambiri.
Sonkhanitsani motsatira dongosolo la disassembly ndi msonkhano.
Maboliti otchinga-lock flange okhala ndi torque yodziwika.
Tsekani mtedza ndi torque yodziwika.
Pambuyo pa kukhazikitsa actuator, valve spool imayendetsedwa kuti izungulire chizindikiro cholowera chofananira pozungulira tsinde kuti valavu itseguke ndi kutseka.
Ngati n'kotheka, yesani kuthamanga kwa chisindikizo ndi ntchito ya valve molingana ndi muyezo mutatha kuyika payipi.
