Valve ya mpirakukhazikitsa:
1. Ayenera kutsimikiziridwa kuti payipi ndi ntchito ya valve yatsukidwa.
2. woyambitsa wavalavu ya mpirantchito molingana ndi kukula kwa chizindikiro cholowera kuti muyendetse kuzungulira kwa tsinde: kuzungulira kutsogolo 1/4 (90 °),valavu ya mpirachatsekedwa.Thevalavu ya mpiraimatsegulidwa pamene kutembenuka kobwerera ndi 1/4 kutembenuka (90 °).
3.Pamene muvi wosonyeza njira ya actuator ikufanana ndi payipi, valve imatsegulidwa;Vavu yotsekedwa pamene muvi uli perpendicular to line.
Valve ya mpirakukonza:
Kukhala ndi moyo wautali wautumiki komanso nthawi yopanda kukonza zidzadalira zinthu zingapo: momwe zimagwirira ntchito, kusunga kutentha / kupanikizika kogwirizana, ndi deta yokwanira ya dzimbiri.
Chidziwitso: pamenevalavu ya mpirachatsekedwa, kuthamanga kwamadzimadzi kumakhalabebe m'thupi la valve
Musanayambe kutumikira, chotsani kuthamanga kwa mzere ndikuyika valavu pamalo otseguka
Chotsani magetsi kapena gwero la mpweya musanayambe kukonza
Lumikizani choyatsira ku chithandizo musanakonze
1. Loko
Ngati culvert yonyamulira ikutha pang'ono, iyenera kutseka mtedza wa tsinde.
Zindikirani: Osatseka, nthawi zambiri kutseka 1/4 mphete ku mphete imodzi, kutayikira kumayima.
2. Bwezerani mpando ndi zisindikizo
A. Chotsani
Siyani valavuyo pamalo otseguka kuti itulutse mkati ndi kunja kwa valavu kuti mupeze zida zowopsa.
Tsekanivalavu ya mpira, chotsani mabawuti ndi mtedza ku ma flanges onse ndikuchotsa valavu kwathunthu ku mapaipi.
Chotsani pagalimoto - chowongolera, cholumikizira cholumikizira, chochapira choletsa kutayikira, mtedza wa tsinde, shrapnel ya butterfly, Gernan, kuvala disc, kunyamula tsinde motsatizana.
Chotsani mabawuti olumikizira chivundikiro ndi mtedza, patulani chivundikiro pathupi, ndikuchotsa chivundikirocho.
Onetsetsani kuti mpirawo uli pamalo "ochoka" kuti muchotse mosavuta m'thupi ndikuchotsa mpando.
Kanikizani tsinde pang'onopang'ono kudutsa dzenje lapakati pa thupi mpaka litachotsedwa, kenako chotsani O-ring ndi mphete yonyamula.
Zindikirani: Chenjerani ndi kupewa kukanda pamwamba pa tsinde ndi kunyamula chidindo cha valve.
B. Kusonkhanitsanso
Yesani ndi kuyang'ana mbali zomwe zikuyang'aniridwa.M'malo mwa mipando ndi ma gaskets a bonnet ndi zosindikizira zokhala ndi zida zosinthira ndizovomerezeka kwambiri.
Sonkhanitsani motsatira dongosolo la disassembly.
Cross-lock flange bolts ndi torque yodziwika.
Mangitsani mtedza ndi torque yodziwika.
Pambuyo kukhazikitsa actuator, tembenuzani tsinde la valve kuti muyendetse spool kuti mutembenuze chizindikiro chofananira cholowera kuti mutsegule ndi kutseka valavu.
Ngati n'kotheka, kuyesa kusindikizira ndi valavu yoyesa ntchito malinga ndi muyezo pambuyo poika mapaipi.
