Mavavu amagawidwa ndi kukula kwadzina / kupanikizika / kutentha / zinthu / kulumikizana / kagwiridwe Kuwonongeka kwachitsulo kumadalira kutentha, makina amtundu wa magawo ogundana, kukhazikika kwa ma sulfide omwe ali muzinthu zopaka mafuta ndi kukana kwawo kwa asidi, nthawi yolumikizana ndi sing'anga ndi chothandizira zotsatira za zitsulo pa ndondomeko nitriding, kutembenuka mlingo wa mamolekyu a zinthu zikuwononga zitsulo zitsulo, etc. 1, valavu dzimbiri, nthawi zambiri amamveka ngati valavu zitsulo zakuthupi mu mankhwala kapena electrochemical chilengedwe ndi chiwonongeko. Popeza dzimbiri limapezeka pochita zinthu modzidzimutsa pakati pa zitsulo ndi malo ozungulira, momwe mungasankhire zitsulo kumalo ozungulira kapena kugwiritsa ntchito zinthu zambiri zosapanga zitsulo zakhala zodetsa nkhawa. 2. Ndizodziwika bwino kuti kuwonongeka kwachitsulo kumakhudza kwambiri moyo, kudalirika ndi moyo wautumiki wa ma valve. Zochita zamakina ndi zowononga pazitsulo zimawonjezera kuchuluka kwa kuvala pamalo olumikizana. Vavu pa ntchito, mikangano padziko kuchuluka kwa kuvala. Panthawi yogwira ntchito ya valve, malo ophwanyika amavalidwa ndikuwonongeka chifukwa cha zochitika zamakina nthawi imodzi ndi kuyanjana kwa mankhwala kapena electrochemical pakati pa zitsulo ndi chilengedwe. Kwa valavu, nyengo yake yogwirira ntchito payipi ndi yovuta; Kukhalapo kwa hydrogen sulfide, carbon dioxide ndi ena organic zidulo mu mafuta, gasi zachilengedwe ndi posungira madzi kumawonjezera kuwononga mphamvu ya pamwamba zitsulo, motero mofulumira kutaya mphamvu zake ntchito. 3, chifukwa cha dzimbiri mankhwala zitsulo zimadalira kutentha, makina katundu wa mikangano mbali, lubricating zipangizo munali sulfide ndi asidi kukana bata ndi sing'anga kukhudzana nthawi ndi zitsulo pa nitriding ndondomeko chothandizira kanthu, dzimbiri mamolekyu a zinthu. pa liwiro zitsulo kutembenuka ndi zina zotero. Choncho, njira ya anticorrosion ya valve yachitsulo (kapena muyeso) ndi kugwiritsa ntchito valavu yopangira zinthu zakhala imodzi mwa mitu ya kafukufuku wamakampani a valve. 4, zitsulo valavu anticorrosion, tingamvetse ngati valavu zitsulo TACHIMATA kuteteza chikhalidwe cha wosanjikiza zoteteza ku dzimbiri (monga utoto, utoto, lubricating zipangizo, etc.), kuti valavu kaya kupanga, kuteteza, mayendedwe. kapena pakugwiritsa ntchito kwake konse sikukhala ndi dzimbiri. 5, zitsulo valavu anticorrosion njira zimadalira nthawi chitetezo chofunika, mayendedwe ndi kutetezedwa, makhalidwe mavavu kapangidwe ndi zipangizo, ndithudi, kuganizira zotsatira zachuma kuchotsa anticorrosion. Gulu la mavavu malinga ndi m'mimba mwake mwadzina / kupanikizika / kutentha / zinthu / mawonekedwe olumikizirana / mawonekedwe opangira Gulu la mavavu malinga ndi m'mimba mwake 1, "valavu yaing'ono" m'mimba mwake mwadzina DN≤40mm 2, "valavu yapakati" m'mimba mwake mwadzina DN50-300mm 3, "valavu lalikulu m'mimba mwake" Mwadzina m'mimba mwake DN350-1200mm valavu 4, "chachikulu m'mimba mwake valavu" mwadzina awiri DN≥1400mm valavu mavavu amaikidwa monga mwadzina mavavu kukula 1, "yaing'ono caliber valavu" mwadzina awiri DN≤40mm valavu 2, "yapakati valavu "caliber valve" m'mimba mwake mwadzina DN50-300mm valavu 3, "valavu yayikulu" m'mimba mwake mwadzina DN350-1200mm valavu 4, "valavu yayikulu m'mimba mwake" mwadzina DN≥1400mm valavu Gulu la mavavu odziyimira pawokha 1, "vacuum vavu" kugwira ntchito ndikotsika kuposa muyezo mumlengalenga kuthamanga valavu 2, "otsika valavu" kuthamanga mwadzina PN≤ 1.6mpa valavu 3, "pakatikati kuthamanga valavu" mwadzina kuthamanga PN2.5-6.4mpa vavu 4, "kuthamanga valavu" kuthamanga mwadzina PN10.0-80.0mpa valavu 5, "wapamwamba kuthamanga valavu" mwadzina kuthamanga PN≥100MPA valavu Malinga sing'anga kutentha valavu gulu 1, "kutentha valavu" T > 450 ℃ valavu 2, "yapakati kutentha valavu" 120 ℃≤ T ≤450 ℃ valavu 3, "vavu wamba kutentha" -40 ℃≤ T ≤120℃ valavu 4, "otsika kutentha valavu" -100℃≤ T ≤-40 ℃ vavu 5, "** valavu kutentha" T
