General Service Vs High-Performance Butterfly Valves: Kodi Pali Kusiyana Kotani?

General Service Butterfly Valves

Mtundu uwu wa valavu yagulugufe ndizomwe zimayendera ponseponse pazantchito zonse. Mutha kuzigwiritsa ntchito pokhudzana ndi mpweya, nthunzi, madzi ndi madzi ena osagwira ntchito kapena mpweya. Mavavu agulugufe agulugufe amatsegula ndi kutseka ndi chogwirira cha malo 10. Mutha kusinthanso kutsegula ndi kutseka kwawo pogwiritsa ntchito choyatsira mpweya kapena magetsi kuti muzimitsa / kuzimitsa, kusuntha komanso kudzipatula.

Mpando wa valavu umaphimba thupi kuti zitsimikizire kuti zinthu zomwe zikugwiritsidwa ntchito sizikukhudzana ndi thupi. Mapangidwe apampandowa ndi abwino kuti azigwira ntchito mu vacuum applications. Mphepete mwa valavu imadutsa mu diski ndipo imamangiriridwa ku diski kudzera pa spline yolimba, yokhala ndi 3 bushings pamwamba ndi pansi zomwe zimakhala ngati shaft yonyamula.

Ubwino umodzi wa ma valve agulugufe wamba ndikuti mapangidwe ake ndi osavuta, kuwalola kuti apangidwe kuti agwirizane ndi ntchito zosiyanasiyana zamapaipi. Kuphatikiza apo, amasindikizidwa pogwiritsa ntchito mitundu yosiyanasiyana ya elastomer, ndipo mutha kusankha mtundu wa elastomer womwe umagwirizana ndi bajeti yanu. Choyipa cha mavavuwa ndikuti ndi ma torque apamwamba kwambiri ndipo zida zapampando sizingathe kupirira kutentha kwambiri komanso kuthamanga kwapamwamba kuposa 285 PSI. Komanso sangagwiritsidwe ntchito m'mapulogalamu akuluakulu, chifukwa amapezeka kukula kwake mpaka 30 in.

Ma Vavu Agulugufe Ochita Bwino Kwambiri

Mavavu agulugufe ochita bwino kwambiri amatha kuthana ndi chilichonse chomwe ma valve agulugufe amatha kukonza, koma amapangidwa kuti azitha kupirira zamadzimadzi komanso ma valve amtundu uliwonse samatha kupirira. Amapangidwa ndi mipando ya PTFE yomwe imatha kuthana ndi zakumwa zamadzimadzi komanso zowononga, mpweya ndi nthunzi. Pamene mavavu agulugufe wamba amapangidwa ndi ma elastomer omwe amatha kukokoloka, mavavu agulugufe ochita bwino kwambiri amagwiritsa ntchito zinthu zolimba ngati graphite kusindikiza mpando. Chowonjezera china ndikuti amabwera kukula kwake mpaka 60 kuti athe kugwiritsidwa ntchito pazinthu zazikulu.

Ziribe kanthu kuti mukukonza zinthu zotani, mutha kupeza valavu yagulugufe yochita bwino kwambiri yomwe imakwaniritsa zosowa zanu. Ngati pulogalamu yanu ingakhale pachiwopsezo cha kutulutsa mpweya wothawa, mutha kugwiritsa ntchito valavu yagulugufe yochita bwino kwambiri yomwe imakhala ndi zisindikizo za tsinde poletsa kutulutsa mpweya. Ngati mapaipi anu akuzizira kwambiri, mutha kupeza mavavu agulugufe ochita bwino kwambiri okhala ndi zokulitsa khosi zomwe zimalola kutsekereza chitoliro.

Mukhoza kupeza ma valve agulugufe opangidwa ndi chitsulo cha carbon, zitsulo zosapanga dzimbiri, ndi zitsulo zina. Zitsulozo zimawotchedwa kotero kuti valavu imatha kupirira kutentha mpaka -320 madigiri F ndi pamwamba mpaka 1200 ° F, ndi kupirira kupanikizika mpaka 1440 PSI. Mavavu agulugufe ambiri ochita bwino kwambiri amakhala ndi maimidwe m'thupi omwe amalepheretsa kuyenda mopitilira muyeso, komanso chithokomiro chokhazikika kuti chiteteze kutuluka kwakunja.
