Valavu ya pulagi ya Dbb ya Industrial Dbb Valavu yokweza pulagi yokweza China wopanga fakitale Wopanga
Kodi valavu ya pulagi ya Dbb ndi chiyani?
Chitsulo chosapakidwa mafutaValavu ya pulagi ya DbbAdapangidwa zaka zoposa 80 zapitazo kuti athetse mavuto omwe analipo ndi ma valve omwe alipo kale mu ntchito yokonza ma catalyst. Popeza ma valve anali bwino kwambiri mu ntchito iyi, adalimbikitsidwanso kuti agwiritsidwe ntchito mu ntchito zina za hash mumakampani opanga mankhwala ndi petrochemical. Popeza ma valve anali bwino kwambiri mu ntchito iyi, adalimbikitsidwanso kuti agwiritsidwe ntchito mu ntchito zina za hash mumakampani opanga mankhwala ndi petrochemical. Kuti tifotokoze chifukwa chake valavu yakhala yopambana kwambiri, pansipa tafotokoza kapangidwe ka valavu kuti ipereke mphamvu zambiri mkati mwake.
MFUNDO YOTSEGULA NDI KUTSEKA KWAValavu ya pulagi ya Dbb
Kutseka kwa valavu:
- 1) tembenuzani chogwirira ndi madigiri 90 kuti njira ya pulagi ikhale yolunjika ku njira ya thupi la valavu
- 2) Kenako tembenuzani gudumu lamanja kuti mutsike pulagi, kuti valavu itseke.
Zinthu zazikulu za valavu ya pulagi ya Dbb
Makhalidwe ndi ubwino waValavu Yokweza Pulagi.
- *Chogulitsachi chili ndi kapangidwe koyenera, kusindikiza kodalirika, magwiridwe antchito abwino kwambiri komanso mawonekedwe okongola.
- *Ikhoza kugwiritsidwa ntchito mumikhalidwe yautumiki mpaka650°C .
- *Zotchinga ziwiri zamakina, zosankha ziwiri za Block & Bleed.
- *Mpando wachitsulo, wokhala ndi mpando wautali, mipando yotetezedwa ku madzi otuluka mwachindunji pamalo otseguka komanso otsekedwa.
- *Malo okhala ndi mipando yolimba (ya stellite) amatha kugwiritsidwa ntchito bwino kwambiri.
- *Palibe mafuta odzola! Palibe kuipitsidwa kwa njira yopangira zinthu.
- * Zipangizo za zigawo ndi kukula kwa ma flanges zitha kukonzedwa moyenera malinga ndi momwe makasitomala amagwirira ntchito, kuti zikwaniritse zosowa zosiyanasiyana za uinjiniya.
Mafotokozedwe aukadaulo a valavu ya pulagi ya Dbb
| Kapangidwe ndi wopanga | API599, API6D |
| M'mimba mwake mwa dzina | 1/2'' ~ 16''( 15mm ~ 400mm) |
| Kalasi yokakamiza | Kalasi 150 ~ Kalasi 1500 |

| Chitsanzo cha ntchito | Chiguduli chogwirira, zida za nyongolotsi, zoyendetsedwa ndi mpweya komanso zamagetsi |
Dziwani: kukula kwa flange yolumikizira ma valve otsatizana kungapangidwe malinga ndi zosowa za makasitomala.
Kugwiritsa ntchito valavu ya pulagi ya Dbb
Valavu ya pulagi ya Dbbimagwiritsidwa ntchito kwambiri m'mikhalidwe yovuta yogwirira ntchito,
- *mankhwala / zinthu zopangidwa ndi petrochemical (zogwiritsidwa ntchito podula)
- *madzimadzi opaka ma crystallizer
- *madzimadzi okhala ndi zinthu zolimba
- *madzimadzi a cryogenic
- *asidi / maziko / njira zolimbitsa thupi
- *mpweya wokhala ndi zinthu zolimba
