Zigawo Zolondola za Valve Zothandizira Mizere Yopangira Zitsulo

Mu mafakitale a zitsulo, kulephera kwa mavavu sikuti nthawi zonse kumakhala chifukwa cha thupi lalikulu la valavu. Nthawi zambiri, ndi ziwalo zamkati—mpando, tsinde, gland—zomwe zimatuluka pansi pa kutentha kwambiri, dzimbiri, kapena kupanikizika. Izi sizinthu wamba. Mu malo osinthira kapena mzere wopangira zinthu mosalekeza, valavu iliyonse imagwira ntchito pansi pa kupsinjika kwapadera kwa njira. Ichi ndichifukwa chake mainjiniya ambiri a zida zachitsulo akusinthira ku zigawo za valavu zopangidwa mwamakonda zomwe zimamangidwa kuti zigwirizane ndi magawo awo enieni a njira.

Ku Sichuan Yining Machinery, timapanga zowonjezera za ma valve zomwe zimagwiritsidwa ntchito popanga zitsulo, kusungunula zinthu zopanda chitsulo, komanso makina otenthetsera otentha. Zinthu zathu zomwe timagwiritsa ntchito nthawi zambiri zimaphatikizapo mipira ya ma valve, tsinde, mipando, ma glands opakira, ndi mabulaketi oyika. Zonsezi zimapangidwa kutengera zojambula zomwe makasitomala amapereka kapena zitsanzo zomwe zilipo, pogwiritsa ntchito zipangizo zoteteza kutentha monga 316L, chitsulo chosapanga dzimbiri cha duplex, kapena A105 chogwiritsidwa ntchito pamwamba.

Zolephera Zofala ndi Momwe Zigawo Zapadera Zimazitetezera
Pochiza ng'anjo yophulika popanda mpweya, mipando yokhazikika ya ma valavu nthawi zambiri imapindika kapena kutayikira pambuyo potentha mobwerezabwereza. Timapereka mipando yopangidwa ndi makina yokhala ndi zolekerera zolimba komanso zosankha zolimba zomwe zimasunga mawonekedwe ake pansi pa kutentha kwa 600°C. Mu mapaipi osinthira okosijeni, mitengo yokhazikika ya ma valavu imatha kutopa. Mitengo yathu yopangidwa kapena yosinthidwa molondola imapangidwa kuti isavutike ndi kutentha komanso kukula komwe kumabwera chifukwa cha kutentha.

Mipira ya ma valvu yomwe imagwiritsidwa ntchito m'madzi otayidwa nthawi zambiri imawonongeka mwachangu chifukwa cha kusweka kwa matope. Pofuna kuthana ndi izi, timapereka mipira yolimba yosapanga dzimbiri kapena yokutidwa ndi zokutira za chrome carbide. Pa mizere yokha, mabulaketi oyika a actuator ayenera kukhalabe ofanana pansi pa kugwedezeka. Mapangidwe athu a bulaketi amadulidwa ndi laser ndikulimbikitsidwa ndi TIG welding, yomangidwa motsatira ISO 5211 kapena zofunikira pa mawonekedwe apadera.

Zipangizo ndi Kukonza
- Chitsulo cha kaboni (A105) chogwiritsidwa ntchito pazinthu zonse
- 316L ndi CF8M yolimbana ndi dzimbiri mu mpweya wa asidi kapena mankhwala
- Chitsulo cha Duplex champhamvu kwambiri yamakina
- Zophimba zomwe mungasankhe: nickel plating yopanda magetsi, nitriding, kapena ceramic overlay

Malo athu ogwirira ntchito amaphatikiza kuponyera, makina a CNC, ndi kukonza pamwamba pa denga limodzi. Izi zimatsimikizira kuti zinthu zikutsatira bwino, kusintha mwachangu, komanso kuwongolera khalidwe nthawi zonse.

Chifukwa Chake Zida za Valve Ndi Zofunika mu Metallurgy
Pakupanga zitsulo, ngakhale vuto laling'ono la ma valavu lingasokoneze kuponyedwa kosalekeza kapena kuchedwetsa ma converter. Kutayika sikungowononga ndalama zokha koma ndi nthawi yogwira ntchito komanso kutayika kwa ntchito. Mwa kusintha zigawo zamkati za ma valavu kukhala zigawo zopangidwa mwamakonda, mafakitale amatha kuwonjezera ma valavu ena, kuchepetsa kutsekedwa kosakonzekera, ndikuwonjezera kudalirika kwa ntchito.

Sitigulitsa ma valve athunthu. Timathandiza opanga ma valve, ophatikiza, ndi magulu okonza kupanga ma valve olimba kuyambira mkati mpaka kunja.

Mapulogalamu:
- Zida za valve ya payipi ya okosijeni yosinthira mpweya
- Ma valve amadzi otulutsa zinyalala mkati
- Ma valve odzipatula othandizira mpweya wa flue
- Mabulaketi ndi tsinde la makina oziziritsira madzi
- Zipando za valve ya pickling line ya acid

Mapeto
Valavu iliyonse mu mphero yachitsulo ili ndi ntchito yoti ichitike. Ntchito yathu ndikuwonetsetsa kuti zigawo zamkati zikuchita bwino—kwa nthawi yayitali, ndi zosintha zochepa, komanso pansi pa zovuta. Zigawo za mavavu opangidwa mwapadera si zapamwamba pakupanga zitsulo. Ndiwo muyezo watsopano.
