Kodi valavu ya mpira ingadutse ndi mtundu wanji?

Mavavu a mpira ndi oyenera pamitundu yosiyanasiyana, kuphatikiza zochitika wamba komanso zovuta zogwirira ntchito, motere:

General work medium:Ma valve a mpirandizoyenera kugwiritsa ntchito zinthu wamba monga madzi, zosungunulira, ma asidi, ndi gasi. Ili ndi mawonekedwe ophatikizika, kusindikiza kodalirika, ndipo malo osindikizira nthawi zambiri amakhala otsekedwa ndi malo ozungulira, omwe sawonongeka mosavuta ndi sing'anga ndipo ndi osavuta kugwira ntchito ndi kusamalira. Mwachitsanzo, thupi la valve la zitsulo zosapanga dzimbiri lopangidwa ndi zitsulo zosapanga dzimbiri monga 304 ndi 316, ndipo zinthu zosindikizira zimatha kusankhidwa kuchokera ku PTFE kapena zisindikizo zolimba zazitsulo, zomwe zimatha kupirira ma TV osiyanasiyana monga ma asidi, gasi, ndi mafuta.

Mikhalidwe yoyipa yogwirira ntchito:Ma valve a mpirandizoyeneranso kugwirira ntchito ndi zinthu zankhanza monga oxygen, hydrogen peroxide, methane, ndi ethylene. Zofalitsa izi zikhoza kukhala ndi makhalidwe monga corrosiveness, flammability, explosiveness, kapena kutentha kwakukulu ndi kupanikizika, ndipo mapangidwe apadera ndi kusankha kwa zinthu za ma valves a mpira akhoza kukwaniritsa zofunikira izi. Mwachitsanzo, mpweya zitsulo mavavu mpira ndi oyenera atolankhani ndi ntchito kutentha osiyanasiyana -100 ℃ mpaka 600 ℃ ndi kuthamanga mlingo wa 1.0-64MPa, ndipo chimagwiritsidwa ntchito mankhwala, mafuta, mphamvu ndi madera ena.

Makanema apadera: Pazofalitsa zapadera monga ulusi ndi tinthu tating'ono tolimba, ma valve a mpira amakhalanso ndi njira zofananira. Mwachitsanzo, pali mphamvu yamphamvu yometa ubweya pakati pa pakati pa V-woboola pakati pa valavu yolimba yosindikizidwa ya V-woboola pakati ndi mpando wazitsulo wazitsulo wotsekedwa ndi aloyi yolimba, yomwe ili yoyenera kwambiri kwa mtundu uwu wa sing'anga. Mavavu amitundu yambiri amatha kuwongolera kuphatikizika, kugawanika, ndi kusuntha kwamayendedwe a media pamapaipi, kuwapangitsa kukhala oyenera pamikhalidwe yomwe imafunikira kuwongolera kovutirapo kwa media.

Media zowononga: Kwa zinthu zowononga kwambiri monga sulfuric acid, madzi a m'nyanja, ndi zina zotero,ma valve a mpiraamatha kukulitsa kukana kwawo kwa dzimbiri pogwiritsa ntchito zida monga zitsulo zosapanga dzimbiri 316L, Hastelloy, kapena zokutira ndi PTFE, zokutira za ceramic, etc.
