一.Kuchita mwamphamvu
Kugwira ntchito kwamphamvu kwa valve kumatanthawuza kuthekera kwa valve kupirira kupanikizika kwapakati.Valavu ndi mankhwala opangidwa ndi makina omwe amanyamula kupanikizika kwa mkati, choncho ayenera kukhala ndi mphamvu zokwanira komanso zolimba kuti zitsimikizire kuti zikugwiritsidwa ntchito kwa nthawi yaitali popanda kusweka kapena kusokoneza.
二.Kusindikiza ntchito
Kusindikiza kwa valavu kumatanthawuza kuthekera kwa gawo lililonse losindikiza la valve kuti asatayike.Ndilo lofunikira kwambiri paukadaulo waukadaulo wa valve.Valavu ili ndi magawo atatu osindikizira: kukhudzana pakati pa magawo otsegulira ndi kutseka ndi malo awiri osindikizira a mpando wa valve;malo ofananira pakati pa kulongedza ndi tsinde la valve ndi bokosi lodzaza;kugwirizana pakati pa thupi la valve ndi bonnet.Kutuluka koyambako kumatchedwa kutayikira kwamkati, komwe kumatchedwa kutsekedwa kosalala, komwe kungakhudze kuthekera kwa valve ya Taike kudula pakati.Kwa ma valve otseka, kutulutsa kwamkati sikuloledwa.Kutulutsa kuwiri komalizaku kumatchedwa kutuluka kwakunja, ndiko kuti, kutulutsa kwapakati kuchokera mkati mwa valavu kupita kunja kwa valavu.Kutayikira kungayambitse kuwonongeka kwa zinthu, kuwononga chilengedwe, komanso kuyambitsa ngozi pakagwa zoopsa kwambiri.Kwa media yoyaka, yophulika, yapoizoni kapena yotulutsa ma radio, kutulutsa kwakunja sikuloledwa, kotero ma valve a Taike ayenera kukhala ndi ntchito yosindikiza yodalirika.
三, yoyenda pakati
Sing'anga ikadutsa mu valve, kuthamanga kwapakati (kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve) kudzachitika, ndiko kuti, valavu imakhala ndi kukana kwina kwa kayendedwe ka sing'anga, ndipo sing'anga imadya kuchuluka kwa madzi. mphamvu zogonjetsa kukana kwa valve.Kuchokera pakuwona kusungirako mphamvu, popanga ndi kupanga ma valve, kukana kwa valve kumalo othamanga kuyenera kuchepetsedwa momwe zingathere.
Mphamvu yokwezera ndi mphindi yokwezera Mphamvu yokwezera ndi mphindi yokwezera zimatanthawuza mphamvu kapena mphindi yomwe iyenera kugwiritsidwa ntchito pa valve kuti itsegule kapena kutseka.Mukatseka valavu, ndikofunikira kupanga chisindikizo china chapadera pakati pa magawo otsegulira ndi kutseka ndi malo awiri osindikizira a mpando, ndipo nthawi yomweyo kugonjetsa kusiyana pakati pa tsinde la valve ndi kulongedza, ulusi pakati pa tsinde la valve ndi nati, ndi chothandizira kumapeto kwa tsinde la valve.Mphamvu yothamanga ya mbali zina zotsutsana, motero, mphamvu yotseka ndi torque yotseka iyenera kugwiritsidwa ntchito.Panthawi yotsegulira ndi kutseka kwa valve, mphamvu yotsegula ndi yotseka yofunikira ndi kutsegula ndi kutseka torque imasinthidwa, ndipo mtengo wapamwamba uli pa nthawi yomaliza yotseka kapena kutsegula Koyamba nthawi yomweyo.Popanga ndi kupanga ma valve, yesetsani kuchepetsa mphamvu yawo yotseka ndi torque yotseka.
四, kutsegula ndi kutseka liwiro
Kuthamanga ndi kutsegula ndi kutseka kumasonyezedwa ndi nthawi yofunikira kuti valve imalize ntchito yotsegula kapena yotseka.Kawirikawiri, palibe zofunikira zokhwima pa kutsegula ndi kutseka kwa valve, koma zina zogwirira ntchito zimakhala ndi zofunikira zapadera pa kutsegula ndi kutseka liwiro.Ngati zina zimafuna kutsegula kapena kutseka mofulumira kuti ziteteze ngozi, zina zimafuna kutseka pang'onopang'ono kuteteza nyundo ya madzi, ndi zina zotero. Izi ziyenera kuganiziridwa posankha mtundu wa valve.
五.Kuchita chidwi ndi kudalirika
Izi zikutanthauza kukhudzika kwa valavu kuti ayankhe kusintha kwa magawo a media.Kwa ma valve omwe ali ndi ntchito zenizeni monga ma throttle valves, ma valve ochepetsera kuthamanga, ndi ma valve oyendetsa, komanso ma valve omwe ali ndi ntchito zenizeni monga ma valve otetezera ndi misampha, kukhudzidwa kwawo kwa ntchito ndi kudalirika ndizofunikira kwambiri zizindikiro za luso lamakono.
六, moyo wautumiki
Zimasonyeza kulimba kwa valve, ndilofunika kwambiri pa ntchito ya valve, ndipo ili ndi tanthauzo lalikulu lachuma.Nthawi zambiri amawonetsedwa potengera kuchuluka kwa kutsegulira ndi kutseka komwe kungathe kutsimikizira zofunikira zosindikizira, komanso kutha kuwonetsedwa molingana ndi nthawi yogwiritsira ntchito.
Pankhani ya mitundu ya ma valve omwe amagwiritsidwa ntchito, makina, zitsulo, petrochemical, mankhwala, zomangamanga m'mizinda ndi mafakitale ena ali ndi mitundu yambiri ya ma valve.Makamaka mumakampani opanga makina, ma valve amitundu yonse amagwiritsidwa ntchito.Kuphatikiza pamakampani opanga makina, ma valve agulugufe amagwiritsidwa ntchito makamaka mu petrochemical ndi zitsulo;ma valve diaphragm amagwiritsidwa ntchito makamaka muzitsulo, mphamvu zamagetsi ndi makampani opanga mankhwala;ma valve cheke amagwiritsidwa ntchito makamaka muzitsulo, makampani opanga mankhwala ndi petrochemical;ma valve oyimitsa amagwiritsidwa ntchito makamaka mumafuta amafuta ndi mankhwala;mavavu mpira zimagwiritsa ntchito mafuta , Chemical makampani ndi zitsulo;valavu yoyang'anira imagwiritsidwa ntchito makamaka m'makampani opanga mankhwala, zitsulo, mphamvu yamagetsi ndi chakudya;valavu yochepetsera kuthamanga imagwiritsidwa ntchito makamaka mu petrochemical, makampani opanga mankhwala ndi zitsulo.
