valavu yotsekedwa kwathunthu ndi zitsulo - Woyang'anira mapaipi a mafakitale
Vavu yotchinga bwino kwambiri, valavu yokhala ndi chitsulo chosindikizira, imagwiritsidwa ntchito kwambiri pamapaipi amafuta m'mafakitale monga mafuta, gasi, mankhwala, ndi zitsulo. Poyerekeza ndi njira zachikhalidwe zolumikizira flange, ili ndi zabwino zake monga kuyika kosavuta, kusindikiza bwino, komanso moyo wautali wautumiki. Nkhaniyi ikupatsirani chidziwitso chatsatanetsatane cha mawonekedwe ndi madera ogwiritsira ntchito mavavu a mpira opangidwa bwino.
1. Makhalidwe apangidwe
Valavu ya mpira yotsekedwa bwino imapangidwa ndi zitsulo zosapanga dzimbiri kapena zitsulo zosagwira kutentha, zokhala ndi mapangidwe osakanikirana omwe safuna kuti awonetsere mbali zowonongeka, kupeŵa vuto la ma valve achikhalidwe omwe amatha kuwonongeka chifukwa cha mawonekedwe akunja. Mapangidwe ake apadera a magawo awiri amatha kuteteza bwino kutayikira kwapakati kuchokera kumbali zonse za valve, kuonetsetsa kuti dongosololi likuyenda bwino komanso lokhazikika.
2. Munda wa ntchito
Mavavu a mpira opangidwa bwino ndi oyenera kupanikizika kwambiri, kutentha kwambiri, komanso mapaipi akulu akulu, makamaka potengera zinthu zoyaka komanso zophulika monga mafuta ndi gasi. M'madera a uinjiniya wamankhwala, zitsulo, ndi mphamvu, ma valve opangidwa ndi welded mpira adagwiritsidwanso ntchito kwambiri, kupereka zitsimikiziro zodalirika zopanga mafakitale.
3. Ubwino waukadaulo
1. Kuchita bwino kwambiri kusindikiza: Valavu yotsekedwa mokwanira imagwiritsa ntchito chitsulo chosindikizira, kuonetsetsa kuti kusindikiza kwa valve ndikwabwino kuposa njira zachikhalidwe zolumikizira flange.
2. Kutentha kwakukulu ndi kukana dzimbiri: Vavu ya mpira yowotcherera mokwanira imatha kupirira kutentha mpaka 300 ℃ ndipo imakhala ndi asidi wabwino komanso kukana dzimbiri zamchere.
3. Kuyika kosavuta: Valavu yowotcherera kwathunthu sikutanthauza kuwotcherera kapena kulumikiza bolt, ndipo imatha kukhazikitsidwa ndi kuwotcherera mwachindunji ku payipi, kupulumutsa kwambiri nthawi yoyika ndi mtengo.
4. Moyo wautali wautumiki: Moyo wautumiki wa ma valve otsekedwa mokwanira ndi otalika kwambiri kuposa ma valve achikhalidwe, kufika zaka makumi angapo kapena kuposerapo.
4, Chidule
Ma valve opangidwa bwino kwambiri asanduka chida chofunikira komanso chofunikira pamapaipi amakampani chifukwa cha mawonekedwe awo apadera komanso magwiridwe antchito apamwamba. M'tsogolomu, ndi kupita patsogolo kwaukadaulo komanso kukula kwa kufunikira kwa msika, mavavu a mpira owotcherera kwathunthu adzakhala ndi gawo lofunikira m'magawo ambiri, kupereka njira zotetezeka komanso zogwira ntchito zopangira mafakitale.
