Kodi muyenera kuyang'ana chiyani mukamagwiritsa ntchito ma valve a mpira?

1. Yapakatikati: Pogwiritsa ntchito valavu ya mpira wosapanga dzimbiri, tcheru chiyenera kulipidwa ngati sing'anga yomwe imagwiritsidwa ntchito ingagwirizane ndi ma valve omwe alipo panopa.Ngati sing'anga yomwe imagwiritsidwa ntchito ndi gasi, nthawi zambiri tikulimbikitsidwa kugwiritsa ntchito chisindikizo chofewa.Ngati ndi madzi, chisindikizo cholimba kapena chosindikizira chofewa chingasankhidwe molingana ndi mtundu wamadzimadzi.Ngati ikuchita dzimbiri, m'malo mwake mugwiritse ntchito zomangira za fluorine kapena zoletsa dzimbiri.

2. Kutentha: Pogwiritsa ntchito valavu ya mpira wosapanga dzimbiri, chisamaliro chiyenera kulipidwa ngati kutentha kwapakati pakugwira ntchito kungagwirizane ndi magawo omwe asankhidwa panopa.Ngati kutentha kuli kwakukulu kuposa madigiri a 180, zipangizo zosindikizira zolimba kapena zipangizo zotentha kwambiri za PPL ziyenera kugwiritsidwa ntchito.Ngati kutentha kuli kwakukulu kuposa madigiri 350, zipangizo zotentha kwambiri ziyenera kuganiziridwa kuti zisinthe.

3. Kupanikizika: Vuto lodziwika bwino la valavu yachitsulo chosapanga dzimbiri lomwe likugwiritsidwa ntchito ndilo kukakamiza.Nthawi zambiri, tikuwonetsa kuti mulingo wopanikizika uyenera kukhala wokwera kwambiri.Mwachitsanzo, ngati kuthamanga kwa ntchito ndi 1.5MPa, timalimbikitsa kuti mulingo wa kuthamanga usakhale 1.6MPa, koma 2.5MPa.Kuthamanga kwakukulu kotereku kungathe kuonetsetsa kuti payipi imagwira ntchito bwino panthawi yogwiritsira ntchito.

4. Valani: Pogwiritsira ntchito, tidzapeza kuti zofunikira zina za mafakitale ndi migodi ndizomwe zimakhala zapamwamba, monga sing'anga ili ndi tinthu tating'onoting'ono tolimba, mchenga, miyala, slurry slag, laimu ndi zofalitsa zina.Nthawi zambiri timalimbikitsa kuti zisindikizo za ceramic zigwiritsidwe ntchito.Ngati zisindikizo za ceramic sizingathe kuthetsa vutoli, ma valve ena ayenera kugwiritsidwa ntchito m'malo mwake.
