Vavu yokonza tsiku ndi tsiku imagwira ntchito kwambiri

Vavu yokonza tsiku ndi tsiku imagwira ntchito kwambiri

Kusamalira 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 ndikukonza 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, pogwira ntchito ya valve, pewani kugogoda pa izo, kapena kuthandizira zinthu zolemera, ndi zina zotero.
Kuyeretsa masitepe
Zigawo za valve ziyenera kudutsa munjira iyi musanayambe kusonkhanitsa:
1, malinga ndi zofunika processing, mbali zina ayenera kuchita kupukuta mankhwala, 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, mbali imodzi ndi sanali nsalu nsalu youma, sangathe kusunga waya mbali ubweya pamwamba, kapena woyera nayitrogeni 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 otsegulira ndi kutseka ndi mpando wa valve awiri osindikizira 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 kukhala kosalala, kumakhudza kuthekera kwa valavu kudula sing'anga.
Main luso ntchito vavu
Choyamba, ntchito yosindikiza ma valve
Zimatanthawuza magawo osindikizira a valve omwe amatha kuteteza kutayikira kwa media, ndiye chizindikiro chofunikira kwambiri chaukadaulo cha valve. Pali magawo atatu osindikizira a valve: kukhudzana pakati pa magawo otsegulira ndi kutseka ndi mpando wa valve awiri osindikizira 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 kukhala kosalala, kumakhudza kuthekera kwa valavu kudula sing'anga. Kwa gulu la block valve, kutulutsa kwamkati sikuloledwa. Kutulutsa kuwiri komalizaku kumatchedwa kutuluka kwakunja, ndiko kuti, kutuluka 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 yotaya
Sing'anga yothamanga imatanthawuza sing'anga kudzera mu valavu imatulutsa kutayika kwapakati (kusiyana kwapakati pasanachitike komanso pambuyo pa valavu), ndiye kuti, valavu imakhala ndi kukana kwina kwa sing'anga, sing'anga kuti igonjetse kukana kwa valavu kumawononga. kuchuluka kwa mphamvu. Kuchokera pakuganizira za kupulumutsa mphamvu, kupanga ndi kupanga ma valve kuti achepetse kukana kwa valve kumalo othamanga momwe mungathere.
Chachitatu, kutsegula ndi kutseka mphamvu ndi kutsegula ndi kutseka mphindi
Kutsegula ndi kutseka mphamvu ndi torque ndi mphamvu kapena ma torque omwe ayenera kugwiritsidwa ntchito kuti atsegule kapena kutseka valve. Tsekani valavu, kufunikira kopanga gawo lotseguka-lotseka ndikutumiza mawonekedwe osindikizira pakati pa kukakamiza kosindikiza kozungulira, komanso kugonjetsa pakati pa tsinde ndi kulongedza, tsinde la valavu ndi pakati pa ulusi wa mtedza, valavu ndodo yomaliza yonyamula mikangano ndi mbali zina za mphamvu yolimbana, choncho ayenera kuyesetsa kutseka ndi mphindi yotseka, potsegula ndi kutseka, valavu imafunika kuti mutsegule ndi kutseka mphamvu yotsegula ndi kusintha kwa torque yotseguka, Mtengo wake wapamwamba uli pa mapeto a 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 liwiro kumasonyezedwa ngati nthawi yofunikira kuti amalize kutsegula kapena kutseka kwa valve. Kuthamanga kwa valve kutsegulira ndi kutseka sikuli zofunikira kwambiri, koma zinthu zina zimakhala ndi zofunikira zapadera kuti mutsegule ndi kutseka liwiro, monga zina zofunika kuti mutsegule kapena kutseka mwamsanga, pakakhala ngozi, zina zofunika kuti mutseke pang'onopang'ono, pakagwa madzi, zomwe ziyenera kuganiziridwa posankha mtundu wa valve.
Chachisanu, kukhudzidwa kwa kayendedwe ndi kudalirika
Kukhudzika kwa zochita ndi kudalirika kumatanthawuza valavu yosinthira magawo apakati, pangani yankho lolingana ndi kuchuluka kwa chidwi. 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 kulimba kwa valavu, ndilo ndondomeko yofunikira ya valavu, ndipo ili ndi tanthauzo lalikulu lachuma. Kawirikawiri pofuna kutsimikizira zofunikira zosindikizira za chiwerengero cha nthawi zowonetsera, zikhoza kuwonetsedwanso pogwiritsa ntchito nthawi.
