Valasi imapitilizabe ndikumaliza ntchito zomwe mwapatsidwa munthawi inayake, ndipo magwiridwe antchito omwe akhazikika pamtengo wotchulidwa amatchedwa olephera. Ntchito ya valavu ikawonongeka, zidzakhala zovuta kwambiri zidzachitika.
1.
Ichi ndiye gawo lalikulu lakuthamanga, kuthamanga, kudzutsa, ndi kutulutsa, ndipo nthawi zambiri zimawoneka m'mafakitale.
Zifukwa zopumira za bokosi lofufuzira ili motere:
Zochita sizigwirizana ndi kutchire, kutentha ndi kukakamiza kwa sing'anga yogwira;
Njira yokwaniritsira ndi yolakwika, makamaka ngati kulongedza konse kumayikidwa pachithunzi, kumatha kutayikira;
- Kulondola kwa makondo kapena kumapeto kwa gawo la valavu sikokwanira, kapena pali ma mungu, kapena pali Nick;
Nyimbo za valavu yalumikizidwa, kapena zodalirika chifukwa chosatetezedwa poyera;
⑤ Chakulu valavu imawerama;
Kulongedza kwa nthawi yayitali ndipo wakalamba;
⑦ The Acress ndiwachiwawa kwambiri.
Njira yothetsera kunyamula kunyamula ndi:
① Kusankha kukonza mafayilo;
②rill molondola;
③ Ngati gawo la valavu silabwino, iyenera kukonzedwa kapena kusinthidwa, ndipo mathero ake ayenera kukhala osachepera № 5, ndipo koposa zonse, ziyenera kufikapo, ndipo pamwambapa, palibe zopunduka;
Tengani njira zotetezera kuteteza dzimbiri, ndipo iwo omwe akhazikika ayenera m'malo;
Kuyika kwa mbale ya valavu ikhale yolimba kapena yosinthidwa;
⑥ Zitsanzi ndi kugwiritsidwa ntchito kwa nthawi yayitali, ziyenera kusinthidwa;
Ntchito ya ⑦ Thegwiritsidwe ntchito iyenera kukhala yokhazikika, yotseguka pang'onopang'ono ndikutseka pang'onopang'ono kuti muchepetse kusintha kwadzidzidzi kapena kupatuka kwapakatikati.
2. Kutulutsa kwa magawo oyandikana nawo
Nthawi zambiri, kutayikira kwa bokosi lofufuzira kumatchedwa kuti kunja kwa kunja, ndipo gawo lotseka limatchedwa kutayikira kwamkati. Kutulutsa kwa magawo otsekera, mkati mwa valavu, sikophweka kupeza.
Kutulutsa kwa magawo otsetsereka kumatha kugawidwa m'magulu awiri: imodzi ndi kutayikira kwa chidindo cha chidindo, ndipo chinacho ndi choponyera muzu wa mphete ya chisindikizo.
Zomwe zimayambitsa kutaya:
Malo okwera sakhala malo abwino;
Mphete yolimba siyikugwirizana kwambiri ndi mpando wa valavu ndi valve disc;
Kulumikizana pakati pa valavu ya valavu ya valavu siyikhala yolimba;
Tsitsi la valavu ya valavu imayang'aniridwa ndipo imapindika, kotero kuti magawo otsetsereka ndi otsetsereka sakhala;
⑤close mwachangu kwambiri, mawonekedwe osindikizira sikugwirizana bwino kapena kwawonongeka kale;
Kusankha zinthu mosayenera, sangathe kupirira zokolola za sing'anga;
⑦Use Valve Valve ndi Phvuve wa pachipata ngati Valve. Malo osindikizira sangathe kulimbana ndi kukokoloka kwa liwiro lalitali;
Pang'onopang'ono media amayamba kuzizira kwambiri valavu ikatsekedwa, kuti nthaka yotseke idzaonekere, ndipo zidzachitika;
Kulumikiza kwamphamvu kumagwiritsidwa ntchito pakati pa malo ena osindikizira ndi chivindikiro cha valavu ndi valve disc, yomwe ndi yosavuta kutulutsa mafuta ozungulira osenda ndi chipongwe;
Valuvuni ⑩
Njira zodzitetezera ndi:
①① muyenera kugwiritsa ntchito mozama, muyenera kuyesa kusamala ndi kutayikira, ndikupeza kutayikira kwa malo osindikizira kapena muzu wa mphete ya chisindikizo, kenako ndikuzigwiritsa ntchito pambuyo pa chithandizo;
Inde ndikofunikira kuti muwone ngati magawo osiyanasiyana a valavu ali bwino. Osagwiritsa ntchito valavu yomwe tsinde la valavu limakhala lopindika kapena lopindika kapena chidutswa cha valavu ndi tsinde la valavu sichilumikizidwe motetezeka;
Valu iyenera kutsekedwa mwamphamvu, osati mwamphamvu. Ngati mukuwona kuti kulumikizana pakati pa chikhomo sikwabwino kapena kumakhala koseketsa, muyenera kutsegulanso kwakanthawi kuti zisavuke, kenako ndikutseka mosamala;
④won kusankha valavu, kungokaniza kokha kwa thupi la valavu yokha, komanso kukana kwa ziwalo zotsekera kuyenera kuziganizira;
⑤ Malinga ndi mawonekedwe a valavuyo komanso kugwiritsa ntchito molondola, zigawo zikuluzikulu zomwe zimafunikira kusintha zomwe zikuyenera kugwiritsa ntchito valavu yovomerezeka;
⑥for mlandu womwe sing'anga umakhazikika ndikutentha kutentha ndi kwakukulu mutatseka valavu, valavu ikutsekedwa mwamphamvu mutazizira;
⑦ Mlandu wa valavu ya valavu, valve disc ndi mphete yopindika imalumikizidwa ndi ulusi, tepi ya PTF ikhoza kugwiritsidwa ntchito ngati kulongedza pakati pa ulusi, kuti palibe kusiyana;
Fyuluta ya RAA iyenera kuwonjezedwa pamaso pa valavu ya valavu yomwe ingagwere.
3. Valani tsinde lokweza kulephera
Zomwe zimapangitsa kuti zikhale zotopetsa ndi izi:
Ulusi wawonongeka chifukwa cha kugwirira ntchito kwambiri;
② Kusowa kwamafuta kapena kulephera kwa mafuta;
Tsitsi la valavu ya valavu imayang'aniridwa ndikupotoza;
Mapeto ake sikokwanira;
Kulekerera koyenera ndiko kosalondola, ndipo kuluma kumakhala kolimba;
⑥ Chatchi valavu imatsekemera.
Mwachitsanzo, kusankha kwa zinthu mosayenera, chifukwa, kachilombo ka valavu ndi valavu tsinde zimapangidwa ndi zinthu zomwezi, zomwe ndizosavuta kuluma;
Matenda a - sing'anga (ponena za valavu yokhala ndi valavu ya tsinde kapena valavu yokhala ndi masamba a tsinde pansi);
⑨ The valavu yotseguka itatetezedwa, ndipo ulusi wa valavu imaphimbidwa ndi fumbi ndi mchenga, kapena kukhazikika kwa mvula, mame, chisanu ndi chipale chofewa.
Njira zopewera:
① Kuchita bwino mosamala, musakakamize potseka, osafika pamalo okwera pomwe ndikutsegulira dzanja limodzi kapena awiri kuti muchepetse mawonekedwe okwanira kuti mukankhire valavu tsinde.
② Checheck momwe thupi limakhalira pafupipafupi ndikusunga mapangidwe abwinobwino;
③osasatseguka ndikutseka valavu yokhala ndi lobwezera wautali. Ogwira ntchito omwe akuzolowera kugwiritsa ntchito khola lalifupi ayenera kuwongolera mphamvu yopepuka kuti apotozetsetsetsetsetsetsetsetsetsetsetsetsetsere.
④ampreod mtundu wa kukonza kapena kukonza kuti mukwaniritse zofunika kuchita;
Zochita ziyenera kugonjetsedwa ndi kutukuka ndikusintha kutentha ndi ntchito zina;
⑥ Chakulu valavu ya tsinde sayenera kupangidwa ndi zinthu zomwezo ngati chovala cha valavu;
⑦ Mukamagwiritsa ntchito pulasitiki ngati valavu tsinde, mphamvu iyenera kufufuzidwa, sikuti ndi vuto laling'ono komanso vuto laling'ono, komanso mphamvu yake yolimba, musagwiritse ntchito;
Chizindikiro cha Varve Conce Chitetezo chiyenera kuwonjezeredwa ku valavu ya mpweya;
⑨fror nthawi zambiri amatsegula valavu, sinthani ma handalheel pafupipafupi kuti muchepetse valavu tsinde.
4. Zina
Kutulutsa kwa gasket:
Cholinga chachikulu ndikuti sichingalimbana ndi kutukuka ndipo sichimazolowera kutentha ndi kukakamizidwa; Ndipo kutentha kumasintha kwa valavu yayitali.
Gwiritsani ntchito mafuta oyenera kugwira ntchito. Onani ngati zinthu za gasket ndizoyenera kwa mavesi atsopano. Ngati sioyenera, iyenera kusinthidwa. Pakutentha kwamphamvu kwambiri, kumangitsa ma bolts kachiwiri pakugwiritsa ntchito.
Thupi losweka:
Nthawi zambiri zimayambitsidwa ndi kuzizira. Nyengo ikayamba kuzizira, valavu imayenera kukhala ndi zotchinga zamafuta ndi njira zogwirira ntchito kutentha. Kupanda kutero, madzi mu valavu ndi mapaipi olumikiza ayenera kusinthidwa pambuyo popanga (ngati pali pulagi pansi pa valavu, pulagi ikhoza kutsegulidwa kukhetsa).
DZIKO LAPANSI:
Chifukwa cha mphamvu kapena kugwira ntchito mwamphamvu kwa wodulira. Itha kupewedwa bola ngati wothandizira komanso anthu omwe akukhudzidwa amamvera.
Gund Loves asweka:
Mphamvu yosagwirizana mukamapondereza kunyamula, kapena zolaula (nthawi zambiri zimaponyera chitsulo). Tsindikani kulongedza, sinthanitsani screw symmetrically, osatero. Mukamapanga, osati kungoyang'ana pamagawo akulu ndi ofunikira, komanso samalani ndi magawo achiwiri monga ma glands, apo ayi zimakhudza kugwiritsa ntchito.
Kulumikizana pakati pa chovala cha valavu ndi mbale ya valavu imalephera:
Valve ya pachipata imatengera mitundu yambiri pakati pa mutu wa valve, ndipo poyambira chipata cha chipata. Makamaka chifukwa chopanga zinthu zopangira. Komabe, wogwiritsa ntchitoyo amathanso kupanga njira yolumikizidwa ya T.
Chipata cha chipata chowirikiza chikho china sichitha kukanikiza chivundikiro champhamvu:
Kusaka kwa chipata chowirikiza chimapangidwa ndi mphero yapamwamba. Kwa ma valve ena pachipata, mphero yapamwamba ndiyosavuta (chitsulo chotsika), ndipo idzavalidwa posachedwa mukagwiritsa ntchito. Wedge yapamwamba ndi chidutswa chaching'ono, ndipo zomwe zagwiritsidwa ntchito sizochuluka. Wogwiritsa ntchito amatha kupanga ndi chitsulo cha kaboni ndikusinthanitsa chitsulo choyambirira.
