Kuyika kwa mavavu a mpira opangidwa bwino

(1) Kukweza.Valve iyenera kukwezedwa m'njira yoyenera.Kuti muteteze tsinde la valavu, musamange unyolo wokweza pamanja, gearbox kapena actuator.Osachotsa zisoti zoteteza kumapeto onse a manja a valve musanayambe kuwotcherera.

(2) Kuwotcherera.Kugwirizana ndi payipi yaikulu ndi welded.Ubwino wa kuwotcherera msoko uyenera kukumana ndi muyezo wa "Radiography of Welded Joints of Disk Flexion Fusion Welding" (GB3323-2005) Gulu II.Nthawi zambiri, kuwotcherera kumodzi sikungatsimikizire ziyeneretso zonse.Choncho, poyitanitsa valavu, wopanga ayenera kufunsa wopanga kuti awonjezere 1.0m kumapeto kwa valve.Sleeve chubu, msoko wowotcherera ukakhala wosayenerera, pali kutalika kokwanira kuti mudule msoko wosayenerera ndikuwotcherera.Pamene valavu ya mpira ndi payipi zimawotchedwa, valavu iyenera kukhala pamalo otseguka 100% kuti valavu ya mpira isawonongeke ndi kuwotcherera slag, ndipo nthawi yomweyo onetsetsani valavu Kutentha kwa chisindikizo chamkati sikunawonongeke. kupitirira madigiri 140 Celsius, ndipo njira zoziziritsira zoyenera zitha kuchitidwa ngati kuli kofunikira.

(3) Kumanga bwino kwa valve.Imatengera kapangidwe kapadera kamangidwe ndipo imakhala ndi mawonekedwe osasamalira.Musanaike m'manda, gwiritsani ntchito zokutira zapadera za Pu kunja kwa valavu.Tsinde la valve limakulitsidwa moyenerera molingana ndi kuya kwa pansi, kotero kuti ogwira ntchito amatha kumaliza ntchito zosiyanasiyana pansi.Pambuyo poikidwa m'manda mwachindunji, ndikwanira kumanga dzanja laling'ono la valve bwino.Kwa njira zachizoloŵezi, sizingathe kukwiriridwa mwachindunji, ndipo zitsime zazikulu za valve ziyenera kumangidwa, zomwe zimapangitsa kuti pakhale malo owopsa otsekedwa, omwe sangagwire ntchito yotetezeka.Panthawi imodzimodziyo, thupi la valve palokha ndi ziwalo zogwirizanitsa bolt pakati pa thupi la valve ndi payipi zidzawonongeka, zomwe zidzakhudza moyo wautumiki wa valve.

Ndi chiyani chomwe chiyenera kutsatiridwa pakukonza valavu ya mpira wowotcherera mokwanira?

Mfundo ndi yakuti mu chikhalidwe chotsekedwa, palinso madzi opanikizika mkati mwa thupi la valve.

Mfundo yachiwiri ndi yakuti musanayambe kukonza, choyamba mutulutseni kuthamanga kwa payipi ndiyeno musunge valavu pamalo otseguka, kenaka mudule mphamvu kapena gasi gwero, ndiyeno mutulutse actuator ku bulaketi, ndipo pokhapokha zonse zomwe zili pamwambazi zikhoza kukonzedwa. .

Mfundo yachitatu ndikupeza kuti kupanikizika kwa mapaipi akumtunda ndi kumtunda kwa valavu ya mpira kumatsitsimutsidwa, ndiyeno disassembly ndi kuwonongeka kungatheke.

Mfundo zinayizi ndizoyenera kusamala panthawi ya disassembly ndi ressembly, kuteteza kuwonongeka kwa kusindikiza pamwamba pa zigawozo, kugwiritsa ntchito zida zapadera kuchotsa O-ring, ndi kumangitsa ma bolts pa flange symmetrically ndi pang'onopang'ono komanso mofanana. pa msonkhano.

Mfundo zisanu: Poyeretsa, choyeretsa chogwiritsidwa ntchito chiyenera kukhala chogwirizana ndi zigawo za rabara, zigawo za pulasitiki, zitsulo zazitsulo ndi ntchito yogwiritsira ntchito mu valve ya mpira.Pamene sing'anga yogwirira ntchito ndi gasi, mafuta angagwiritsidwe ntchito kuyeretsa zitsulo, ndipo Kwa ziwalo zopanda zitsulo, muyenera kugwiritsa ntchito madzi oyera kapena mowa kuti muyeretse.Zigawo zomwe zavunda zimatsukidwa ndi kuviika m'madzi, ndipo zitsulo zomwe sizinawonongeke zimatsukidwa ndi nsalu yoyera komanso yabwino kwambiri ya silika yoviikidwa muzitsulo zoyeretsera, ndipo mafuta onse omwe amamatira pakhoma ayenera kukhala. kuchotsedwa., dothi ndi fumbi.Komanso, sichingasonkhanitsidwe mwamsanga mutatha kuyeretsa, ndipo chikhoza kuchitidwa pambuyo poti woyeretsayo wasungunuka.
