Vavu yokonza tsiku ndi tsiku imagwira ntchito kwambiri

Valavu yokonza tsiku ndi tsiku ntchito yaikulu yaukadaulo Kukonza tsiku ndi tsiku 1. Chisamaliro chiyenera kuperekedwa ku malo osungira a valve. Iyenera kusungidwa m'chipinda chowuma ndi mpweya wokwanira ndikutsekeka kumapeto kwa mayendedwe. 2, valavu iyenera kuyang'aniridwa nthawi zonse, ndikuchotsa dothi pamenepo, kupaka mafuta odana ndi dzimbiri pamwamba pake. 3. Pambuyo pa kukhazikitsa ndi kugwiritsa ntchito valve, iyenera kukonzedwa nthawi zonse kuti iwonetsetse ntchito yake yachibadwa. 4. Yang'anani ngati valavu yosindikizira yatha ndikuikonza kapena kuisintha molingana ndi momwe zilili. 5, yang'anani kuvala kwa ulusi wa trapezoidal wa tsinde ndi mtedza wa tsinde, ngati kulongedza kwake ndi kwachikale komanso kosavomerezeka, ndikuchitanso zofunikira. 6, ntchito yosindikiza ya valve iyenera kuyesedwa kuti iwonetsetse kuti ikugwira ntchito. 7. Valavu yomwe ikugwira ntchito iyenera kukhala yosasunthika, ma bolts pa flange ndi bracket ali athunthu, ulusi sunawonongeke, ndipo palibe chochititsa chidwi. 8, ngati gudumu lamanja latayika, liyenera kukhala lokonzekera nthawi, ndipo silingasinthidwe ndi wrench yosinthika. 9. Kulongedza gland sikuloledwa kupotozedwa kapena popanda chilolezo chotsitsa. 10, ngati malo ogwiritsira ntchito ma valve ndi oipa kwambiri, osatetezeka ku mvula, matalala, fumbi, mchenga ndi kuipitsidwa kwina, ziyenera kuikidwa pa chivundikiro choteteza tsinde. 11, valavu pa sikelo iyenera kukhala yokwanira, yolondola, yomveka, chisindikizo cha valve, kapu. 12, kutchinjiriza jekete sayenera kugwa, ming'alu. 13, pogwiritsira ntchito valavu, pewani kugogoda pa izo, kapena kuthandizira zinthu zolemetsa, ndi zina zotero. pamwamba sangakhale ndi processing burr, etc.; 2. Ziwalo zonse zadetsedwa; 3, pickling passivation pambuyo degreasing, kuyeretsa wothandizila lilibe phosphorous; 4, pickling oyeretsedwa ndi madzi oyera pambuyo kutsuka, sangakhale ndi zotsalira mankhwala, carbon zitsulo mbali sanatchule sitepe iyi; 5, mmodzi ndi mmodzi mbali ndi sanali nsalu nsalu youma, sangathe kusunga waya mbali ubweya pamwamba, kapena woyera asafe youma; 6. Pukutani zigawozo chimodzi ndi chimodzi ndi nsalu zosalukidwa kapena pepala la sefa yolondola yodetsedwa ndi mowa weniweni mpaka palibe mtundu wakuda. Ntchito yayikulu yaukadaulo ya ma valve osindikiza zigawo za kuthekera koletsa kutayikira kwa media, ndiye chizindikiro chofunikira kwambiri chaukadaulo cha valve. Pali magawo atatu osindikizira a valve: kukhudzana pakati pa magawo otsegula ndi otseka ndi mpando wa valve awiri osindikiza pamwamba; Kunyamula ndi tsinde la valve ndi kutengera bokosi lofananira; Kulumikizana kwa thupi kupita ku bonati. Chimodzi mwazomwe zimatuluka kale zimatchedwa kutayikira kwamkati, komwe nthawi zambiri kumanenedwa kuti ndi kosalala, kumakhudza kuthekera kwa valavu kudula sing'anga. Ntchito yayikulu yaukadaulo ya valavu Choyamba, ntchito yosindikiza mavavu Imatanthawuza magawo osindikiza a valve omwe amatha kuteteza kutulutsa kwa media, ndiye chizindikiro chofunikira kwambiri chaukadaulo cha vavu. Pali magawo atatu osindikizira a valve: kukhudzana pakati pa magawo otsegula ndi otseka ndi mpando wa valve awiri osindikiza pamwamba; Kunyamula ndi tsinde la valve ndi kutengera bokosi lofananira; Kulumikizana kwa thupi kupita ku bonati. Chimodzi mwazomwe zimatuluka kale zimatchedwa kutayikira kwamkati, komwe nthawi zambiri kumanenedwa kuti ndi kosalala, kumakhudza kuthekera kwa valavu kudula sing'anga. Kwa gulu la block valve, kutulutsa kwamkati sikuloledwa. Kutulutsa kuwiri komalizaku kumatchedwa kutuluka kwakunja, ndiko kuti, kutulutsa kwa media kuchokera ku valavu kupita ku valavu kunja. Kutayikira kungayambitse kuwonongeka kwa zinthu, kuwononga chilengedwe, kungayambitsenso ngozi. Kwa media yoyaka, yophulika, yapoizoni kapena yotulutsa ma radio, kutayikira sikuloledwa, kotero valavu iyenera kukhala ndi ntchito yosindikiza yodalirika. Awiri, sing'anga yothamanga Kuthamanga kumatanthawuza sing'anga kupyolera mu valavu idzatulutsa kutayika kwa mphamvu (kusiyana kwapakati pasanayambe ndi pambuyo pa valve), ndiko kuti, valavu imakhala ndi kukana kwina kwapakati, pakati kuti igonjetse kukana. valavu idzadya kuchuluka kwa mphamvu. Kuchokera pakuganizira za kupulumutsa mphamvu, kupanga ndi kupanga ma valve kuti achepetse kukana kwa valve kumalo othamanga momwe mungathere. Katatu, kutsegula ndi kutseka mphamvu ndi kutsegula ndi kutseka mphindi Kutsegula ndi kutseka mphamvu ndi torque ndi mphamvu kapena torque zomwe ziyenera kugwiritsidwa ntchito kutsegula kapena kutseka valve. Tsekani valavu, kufunikira kopanga gawo lotseguka-lotseka ndikutumiza mawonekedwe osindikizira pakati pa kusindikiza kwapamwamba pawiri, komanso kugonjetsa pakati pa tsinde ndi kulongedza, tsinde la valavu ndi pakati pa ulusi wa mtedza, valavu ndodo yotsiriza kubala mikangano ndi mbali zina za mphamvu yolimbana, choncho ayenera kuyesetsa kutseka ndi mphindi yotseka, potsegula ndi kutseka, valavu ikufunika kuti mutsegule ndi kutseka mphamvu ndi kusintha kwa torque yotseguka, Kufunika kwake kwakukulu kuli kumapeto kwa mphindi yotsekedwa kapena kumayambiriro kwa mphindi yotseguka. Mavavu ayenera kupangidwa ndi kupangidwa kuti achepetse mphamvu yotseka ndi torque yotseka. Chachinayi, kutsegula ndi kutseka liwiro Kutsegula ndi kutseka kumasonyezedwa ngati nthawi yofunikira kuti mutsirize ntchito yotsegula kapena yotseka ya valve. Kuthamanga kwa valve kutsegulira ndi kutseka sikuli zofunikira kwambiri, koma zinthu zina zimakhala ndi zofunikira zapadera zotsegula ndi kutseka liwiro, monga zina zofunika kuti mutsegule kapena kutseka mwamsanga, pakakhala ngozi, zina zofunika kuti mutseke pang'onopang'ono, ngati madzi agunda, zomwe ziyenera kuganiziridwa posankha mtundu wa valve. Chachisanu, mayendedwe tilinazo ndi kudalirika Action tilinazo ndi kudalirika amatanthauza valavu kwa sing'anga chizindikiro kusintha, kupanga poyankha lolingana ndi mlingo tilinazo. Kwa valavu yamagetsi, valavu yochepetsera kuthamanga, valavu yoyendetsa ndi ma valve ena omwe amagwiritsidwa ntchito pokonza magawo apakati komanso chitetezo, valve ya msampha ndi ma valve ena omwe ali ndi ntchito zinazake, mphamvu zake zogwira ntchito komanso kudalirika ndizofunikira kwambiri zizindikiro za luso lamakono. Chachisanu ndi chimodzi, moyo wautumiki Moyo wautumiki umatanthawuza kukhazikika kwa valve, ndilofunika kwambiri pa ntchito ya valve, ndipo ili ndi tanthauzo lalikulu la zachuma. Kawirikawiri pofuna kutsimikizira zofunikira zosindikizira za chiwerengero cha nthawi zofotokozera, zikhoza kuwonetsedwanso pogwiritsa ntchito nthawi.
