Kupewa ndi Kuchiza kwa Kuwonongeka kwa Valve ya Gulugufe

Kodi dzimbiri ndi chiyanivalavu butterfly?

Kuwonongeka kwa ma valve agulugufe nthawi zambiri kumamveka ngati kuwonongeka kwa zinthu zachitsulo za valve pansi pa zochitika za mankhwala kapena electrochemical chilengedwe. Popeza kuti chodabwitsa cha "kudzimbirira" chimachitika polumikizana modzidzimutsa pakati pa zitsulo ndi malo ozungulira, momwe mungapatulire zitsulo kuchokera kumadera ozungulira kapena kugwiritsa ntchito zinthu zambiri zopanda zitsulo zopangidwa ndi zitsulo ndizofunika kwambiri popewa dzimbiri. Thupi lavalavu ya butterfly(kuphatikizapo chivundikiro cha valve) chimakhala cholemera kwambiri cha valavu ndipo chimagwirizana pafupipafupi ndi sing'anga, kotero valavu ya butterfly nthawi zambiri imasankhidwa kuchokera ku thupi.

Pali mitundu iwiri yokha ya valavu thupi dzimbiri wavalavu butterfly, zomwe ndi corrosion chemical and electrochemical corrosion. Kuchuluka kwake kwa dzimbiri kumatsimikiziridwa ndi kutentha, kupanikizika, mankhwala a sing'anga, ndi kukana kwa dzimbiri kwa valavu ya thupi. Mlingo wa dzimbiri ukhoza kugawidwa m'magulu asanu ndi limodzi:

1. Kukana kwathunthu kwa dzimbiri: kuchuluka kwa dzimbiri ndi zosakwana 0.001 mm / chaka;

2. Kukana kwambiri kwa dzimbiri: mlingo wa 0.001-0.01 mm / chaka;

3. Kukana kwa dzimbiri: kuchuluka kwa dzimbiri 0.01-0.1 mm / chaka;

4. Kuchuluka kwa dzimbiri: kuchuluka kwa dzimbiri 0.1-1.0 mm / chaka;

5. Kusawonongeka kwa dzimbiri: kuchuluka kwa dzimbiri 1.0-10 mm / chaka;

6. Kukana kopanda dzimbiri: kuchuluka kwa dzimbiri ndi kwakukulu kuposa 10 mm / chaka.

Momwe mungapewere dzimbirivalavu butterfly?

The anti-corrosion of the valve body of the butterfly valve is makamaka chifukwa cha kusankha kolondola kwa zipangizo. Ngakhale kuti chidziwitso cha anti-corrosion ndi cholemera kwambiri, sichapafupi kusankha choyenera, chifukwa vuto la dzimbiri ndi lovuta kwambiri, mwachitsanzo, asidi a sulfuric amawononga kwambiri chitsulo pamene ndende imakhala yochepa, ndipo pamene ndende ili pamwamba, imapangitsa chitsulo kupanga filimu yodutsa, yomwe ingalepheretse kuwonongeka; Hydrogen imangowoneka kuti imakhala yowonongeka kwambiri ndi chitsulo pa kutentha kwakukulu ndi kupanikizika, ndipo ntchito yowonongeka kwa mpweya wa chlorine siikulu ikakhala youma, koma ntchito yowonongeka imakhala yamphamvu kwambiri pamene pali chinyezi china, ndipo zipangizo zambiri sizingagwiritsidwe ntchito. Kuvuta kusankha zipangizo za thupi la valve ndikuti sitingathe kungoganizira za zovuta zowonongeka, komanso kuganizira zinthu monga kupanikizika ndi kutentha kwa kutentha, kaya ndi zachuma, komanso ngati n'zosavuta kugula. Choncho muyenera kukhala tcheru.

1. Chachiwiri ndikutenga miyeso ya mizere, monga lead, aluminiyamu, mapulasitiki a engineering, mphira wachilengedwe ndi labala osiyanasiyana opangidwa. Ngati zinthu zapakati zilola, iyi ndi njira yopulumutsira.

2. Chachitatu, pamene kupanikizika ndi kutentha sikuli kwakukulu, chinthu chachikulu cha valve butterfly chopangidwa ndi fluorine nthawi zambiri chimakhala chothandiza kwambiri popewa dzimbiri.

3. Kuonjezera apo, kunja kwa thupi la valve kumawonongekanso ndi mlengalenga, ndipo chitsulo cha ductile chimatetezedwa ndi nickel plating.

TWS posachedwa idzayambitsa mzere watsopano wa anti-corrosion product, kuphimba njira zonse za valve mongavalavu butterfly, ma valve pachipata, fufuzani ma valvendi ma valves a mpira, ndi zina. Mndandanda wazinthuzi umagwiritsa ntchito ukadaulo wapamwamba wokana dzimbiri komanso njira zapadera zothandizira kuti zisungidwe bwino komanso kukhazikika kwantchito pansi pamikhalidwe yovuta kwambiri yogwirira ntchito. Tadzipereka kupatsa makasitomala zinthu zolimba zama valve zamakampani, kukulitsa moyo wautumiki wa zida, kuchepetsa ndalama zosamalira moyo wawo wonse.kutalikakuzungulira, ndikuthandizira makasitomala kupeza zisankho zamtengo wapatali zogula.
