Ulamuliro Wokhazikika wa Fluid Mumikhalidwe Yovuta Ndi Valve Yatsopano Yamipingo iwiri
1. Kapangidwe ndi mawonekedwe a welded awiri chidutswa valavu mpira
Valavu yowotcherera yokhala ndi zidutswa ziwiri imakhala ndi matupi awiri a valve olumikizidwa ndi kuwotcherera. Mpira uli pakati pa matupi awiri a valve. Madziwo amatsegulidwa ndikutsekedwa ndikuzungulira mpirawo. Dongosololi lili ndi zinthu zotsatirazi:
Mphamvu yayikulu: Njira yolumikizira yolumikizira imapangitsa kuti thupi la valve likhale ndi mphamvu zambiri komanso kusindikiza, ndipo limatha kupirira kupsinjika kwakukulu ndi kusinthasintha kwa kutentha.
Kusindikiza kwabwino kwambiri: Zokwanira zolondola komanso zosindikizira zimagwiritsidwa ntchito pakati pa mpira ndi mpando wa valve kuti zitsimikizire kuti palibe kutayikira komwe kutsekedwa.
Kukana kwa corrosion: Thupi la valve nthawi zambiri limapangidwa ndi zinthu zosagwira dzimbiri monga zitsulo zosapanga dzimbiri ndipo zimatha kutengera zinthu zosiyanasiyana zowononga.
Kuchita kosavuta: Mpira ukhoza kutsegulidwa ndi kutsekedwa pozungulira madigiri 90, ndikuyankha mwachangu komanso kuwongolera kutali.
2. Kugwiritsa ntchito valavu ya welded-piece-ball valve muzovuta zogwirira ntchito
Ma valve opangidwa ndi zidutswa ziwiri amagwiritsidwa ntchito kwambiri pazifukwa zovuta zotsatirazi chifukwa chakuchita bwino kwambiri:
Kutentha kwapamwamba komanso malo othamanga kwambiri: Vavu yopangidwa ndi zidutswa ziwiri imatha kupirira kutentha kwambiri komanso malo othamanga kwambiri, monga mapaipi amafuta, mankhwala ndi mafakitale ena. M'madera awa, ma valve amafunika kupirira kutentha kwambiri komanso kusinthasintha kwamphamvu, ndipo njira yolumikizira yolumikizira imatha kutsimikizira mphamvu ndi kusindikiza kwa ma valve.
TV zowononga: Vavu ya mipira iwiri yowotcherera imapangidwa ndi zinthu zolimbana ndi dzimbiri ndipo imatha kutengera zinthu zosiyanasiyana zowononga, monga sulfuric acid, hydrochloric acid, ndi zina zambiri. nthawi, choncho ayenera kukhala bwino dzimbiri kukana.
Nthawi zambiri opareshoni: Valovu yowotcherera yokhala ndi magawo awiri ndi yosavuta kugwiritsa ntchito ndipo imayankha mwachangu, ndipo ndiyoyenera kugwirira ntchito pafupipafupi. Mwachitsanzo, machitidwe owongolera madzimadzi m'mafakitale monga mphamvu yamagetsi ndi zitsulo zimafunikira kusintha pafupipafupi kwamadzimadzi komanso kuthamanga. Ma valve opangidwa ndi zidutswa ziwiri amatha kuyankha mwachangu ndikuwongolera bwino.
3. Kusamalira ndi kasamalidwe ka welded mavavu awiri mpira
Pofuna kuonetsetsa kuti ntchito yokhazikika ya nthawi yayitali ya welded two-piece valve valve pansi pa zovuta zogwirira ntchito, kukonza nthawi zonse ndi kuyang'anira kumafunika. Nazi malingaliro ena:
Yang'anani nthawi zonse ntchito yosindikiza ya valve ndikuthana nayo mwamsanga ngati pali kutayikira.
Tsukani ndi kuthira mafuta mavavu pafupipafupi kuti muchepetse kugundana ndi kutha.
Yang'anani pafupipafupi kugwirizana kwa ma valve ndi zomangira kuti muwonetsetse kuti ndizolimba komanso zodalirika.
Mavavu amayesedwa pafupipafupi ndikuwunikidwa kuti atsimikizire kuti ndi olondola komanso odalirika.
4. Mwachidule
Ndi mphamvu zake zazikulu, kusindikiza kwabwino kwambiri, kukana dzimbiri komanso kugwira ntchito kosavuta, valavu yowotcherera yokhala ndi zidutswa ziwiri imapereka chitsimikizo cholimba cha kuwongolera kwamadzi pansi pazovuta zogwirira ntchito. Kupyolera mu kukonza ndi kuyang'anira nthawi zonse, valavu ikhoza kutsimikiziridwa kuti ikhale yogwira ntchito bwino komanso yodalirika pakugwiritsa ntchito nthawi yayitali. Ndi chitukuko chosalekeza chaukadaulo wamafakitale, ma welded ma valve awiri a mpira adzagwiritsidwa ntchito m'magawo ambiri ndikuchita gawo lalikulu.
