DF08-02 cheke valavu yotsekera katiriji mpira wosindikizira

1. Yang'anani ngati pachimake chake chatsekedwa: Mwachitsanzo, kusiyana kwa makwerero pakati pa batani lakunja lapakati la valavu ndi mkati mwa bowo la thupi la valavu ndi laling'ono kwambiri (makamaka pamene valavu yomwe yangogwiritsidwa ntchito kumene siinavalidwe) , ndipo dothi limalowa mumpata wokwera pakati pa dzenje la thupi la valavu ndi pachimake valavu, ndipo valavu ya valve ya njira imodzi imakhala yotseguka kapena yotsekedwa.Ikhoza kutsukidwa ndi kuchotsedwa.

2. Yang'anani ngati valavu yomwe ili m'mphepete mwa bowo la valavu yatsekedwa, ndikutseka pakati pa valavu ya hydraulic ya njira imodzi pamalo otseguka.

3. Yang'anani ngati mzere wolumikizana pakati pa mphutsi ya valve ndi mpando wa valve ukhoza kusindikizidwa: mwachitsanzo, pali dothi lomwe latsekedwa pamzere wolumikizana kapena kusiyana pa mzere wokhudzana ndi mpando wa valve, womwe sungathe kusindikizidwa.Panthawiyi, mukhoza kuyang'ananso m'mphepete mwa mkati mwa mzere wolumikizana pakati pa mpando wa valve ndi pakati pa valve.Ngati zapezeka, ziyeretseni munthawi yake.Pamene mpando wa valve uli ndi mpata, ukhoza kugwedezeka kwa watsopano.

4. Yang'anani kugwirizana pakati pa pakati pa valavu ndi dzenje la thupi la valavu: chilolezo choyenerera pakati pa nthiti ya kunja kwa valavu ndi m'mimba mwake D ya bowo la thupi la valavu ndi lalikulu kwambiri, kotero kuti valavu ikhoza kuyandama mozungulira.Mu Chithunzi 2-14, pali dothi lokhalokha, ndipo nsonga ya valve imachoka pakati pa mpando wa valve (eccentricity e) ', zomwe zimapangitsa kuti kutulutsa kwamkati kuchuluke, ndipo chigawo cha valve cheke chidzatsegulidwa mokulirapo.

5. Yang'anani kasupe kuti muwone ngati akusowa kapena kasupe wathyoka, ndiye kuti akhoza kuwonjezeredwa kapena kusinthidwa.

Zomwe zili pamwambazi ndizokhudza kuthetsa kulephera kwa hydraulic one-way valve.Nthawi zambiri, titha kuwona vuto kuchokera pamfundo izi.Inde, ngati tiyang'ana molingana ndi mfundozi ndipo osapeza kanthu, tikhoza kungoyitana katswiri wokonza kukonza kuti awone.

Monga tonse tikudziwa, vavu ya hydraulic ndi mtundu wazinthu zodzipangira zokha zomwe zimagwiritsidwa ntchito ndi mafuta opanikizika, omwe amatha kuyendetsedwa bwino ndi mafuta opanikizika.Nthawi zambiri, imagwiritsidwa ntchito limodzi ndi ma electromagnetic pressure distribution valve valve, ndipo itha kugwiritsidwa ntchito kuwongolera patali mafuta, madzi ndi mapaipi a hydropower station.Chigawo chapakati cha valavu ndi hydraulic valve block, yomwe imagwira ntchito yofunika kwambiri poyang'anira njira, kuthamanga ndi kutuluka kwa madzi.

Kugwiritsiridwa ntchito sikungangowonjezera kupanga ndi kuyika kwa hydraulic system, komanso kumathandizira kusakanikirana ndi kukhazikika kwa hydraulic system, zomwe zimathandiza kuchepetsa mtengo wopangira ndikuwongolera kulondola ndi kudalirika.
