Kukhala ndi moyo wautali wautumiki komanso nthawi yopanda kukonza zidzadalira zinthu izi: machitidwe abwino ogwirira ntchito, kusunga kutentha kogwirizana / kupanikizika, ndi deta yokwanira ya dzimbiri.
Pamene valavu ya mpira yatsekedwa, pamakhalabe mphamvu yamadzimadzi mu thupi la valve.
Musanakonzekere: masulani kuthamanga kwa mapaipi, sungani valavu pamalo otseguka, chotsani mphamvu kapena gwero la mpweya, ndikulekanitsa cholumikizira ku bulaketi.
Pamaso pa disassembly ndi kuwonongeka ntchito, kuthamanga kwa mapaipi kumtunda ndi kunsi kwa mtsinje wa valavu mpira ayenera kufufuzidwa.
Pa disassembly ndi ressembly, kusamala kuyenera kuchitidwa kuti zisawonongeke pazitsulo zosindikizira za zigawo, makamaka zosagwirizana ndi zitsulo.Zida zapadera ziyenera kugwiritsidwa ntchito pochotsa mphete za O.
Mabawuti pa flange ayenera kumangika molingana, pang'onopang'ono, komanso mofanana.
Chotsukiracho chiyenera kukhala chogwirizana ndi mphira wa valavu ya mpira, pulasitiki, zitsulo, ndi sing'anga yogwirira ntchito (monga gasi).Pamene sing'anga ntchito ndi gasi, mbali zitsulo akhoza kutsukidwa ndi mafuta (GB484-89).Tsukani mbali zopanda zitsulo ndi madzi oyera kapena mowa.
Zigawo zopanda zitsulo ziyenera kuchotsedwa muzitsulo zoyeretsera nthawi yomweyo, ndipo zisalowerere kwa nthawi yaitali.
Pambuyo poyeretsa, ndikofunikira kusokoneza choyeretsa khoma (kupukuta ndi nsalu ya silika yomwe sinanyowedwe mu woyeretsa) kuti isonkhane, koma sayenera kuyimitsidwa kwa nthawi yayitali, apo ayi, ichita dzimbiri komanso kuipitsidwa ndi fumbi.
Zigawo zatsopano zimayenera kutsukidwa musanaziike.
Pamsonkhanowu, pasakhale zinyalala zachitsulo, ulusi, mafuta (kupatulapo ntchito yeniyeni), fumbi ndi zonyansa zina, zinthu zakunja, ndi kuipitsidwa kwina, kumamatira kapena kukhala pamwamba pa zigawozo kapena kulowa mkati.Tsekani tsinde ndi mtedza ngati pali kutayikira pang'ono pakulongedza.
A), kuchotsa
Zindikirani: Osatseka mwamphamvu, nthawi zambiri 1/4 mpaka 1 kutembenukira kwina, kutayikirako kumayima.
Ikani valavu pamalo otseguka, pukuta, ndi kuchotsa zinthu zoopsa zomwe zingakhalepo mkati ndi kunja kwa thupi la valve.
Tsekani valavu ya mpira, chotsani ma bolts ndi mtedza pa flanges kumbali zonse ziwiri, ndiyeno muchotseretu valavu ku chitoliro.
Phatikizani chipangizo choyendetsa motsatira - actuator, cholumikizira, chotchingira loko, nati ya tsinde, shrapnel ya butterfly, glam, pepala losavala, kunyamula tsinde.
Chotsani chivundikiro cha thupi cholumikiza mabawuti ndi mtedza, patulani chivundikiro cha valve ku thupi la valve, ndikuchotsani chivundikiro cha valve.
Onetsetsani kuti mpirawo uli pamalo otsekedwa, zomwe zimapangitsa kuti zikhale zosavuta kuchotsa m'thupi, ndiye kuchotsa mpando.
Kanikizani tsinde la valve pansi pa dzenje la valavu mpaka litachotsedwa, kenaka tulutsani O-ring ndi kulongedza pansi pa tsinde la valve.
B), kuphatikiza.
Zindikirani: Chonde gwirani ntchito mosamala kuti musakanda pamwamba pa tsinde la valavu ndi gawo losindikiza la bokosi loyika valavu.
Kuyeretsa ndi kuyang'ana mbali zowonongeka, zimalimbikitsidwa kwambiri kuti musinthe zisindikizo monga mipando ya valve, ma gaskets a bonnet, ndi zina zotero ndi zida zosinthira.
Sonkhanitsani motsatira dongosolo la disassembly.
Limbani ma bolts olumikizirana ndi flange ndi torque yomwe mwatchulidwa.
Mangitsani mtedza wa tsinde ndi torque yomwe mwatchulayo.
Mukayika chowongolera, lowetsani chizindikiro chofananira, ndikuyendetsa pachimake cha valve kuti muzungulire pozungulira tsinde la valavu, kuti valavu ifike pamalo osinthira.
Ngati n'kotheka, chonde yesani kuyesa kusindikiza ndikuyesa magwiridwe antchito pa valve molingana ndi miyezo yoyenera musanayikenso payipi.
