Valavu yapamwamba kwambiri ya DIN-EN Globe fakitale yaku China
Kodi valavu ya dziko lapansi ndi chiyani?
Valavu ya padziko lonseYapangidwa ndikupangidwa motsatira muyezo wakale wa Germany, DIN ndi masiku ano muyezo wa ku Europe EN13709.imagwiritsidwa ntchito kwambiri m'maiko a European Union.
Ndi valavu yotseka yoyenda molunjika yomwe imagwiritsidwa ntchito kuyambitsa, kuyimitsa kapena kuwongolera kuyenda kwa madzi pogwiritsa ntchito chiwalo chotseka chomwe chimatchedwa diski. Kutseguka kwa mpando kumasintha molingana ndi kuyenda kwa diski komwe kuli koyenera pa ntchito zokhudzana ndi kuwongolera kuyenda kwa madzi. Ma valavu a DIN-EN Globe ndi oyenera kwambiri ndipo amagwiritsidwa ntchito kwambiri kuwongolera kapena kuletsa kuyenda kwa madzi kapena mpweya kudzera mu chitoliro kuti azitha kupondereza ndikuwongolera kuyenda kwa madzi ndipo nthawi zambiri amagwiritsidwa ntchito m'mapaipi ang'onoang'ono.
aMa valve a globeingagwiritsidwenso ntchito poyendetsa ma valve. Ma valve ambiri okhala ndi malo amodzi amagwiritsa ntchito kapangidwe ka khola kapena kosungira kuti asunge mphete ya mpando, kupereka chitsogozo cha pulagi ya valve, komanso kupereka njira yokhazikitsira makhalidwe enaake a valavu. Itha kusinthidwa mosavuta posintha magawo odulira kuti asinthe mawonekedwe a mayendedwe kapena kupereka mayendedwe ocheperako, kuchepetsa phokoso, kapena kuchepetsa kapena kuchotsa cavitation.
nthawi zambiri pamakhala mapangidwe atatu akuluakulu a thupi kapena mapangidwe aMa valve a globe:
- 1). Chitsanzo Chokhazikika (komanso monga Chitsanzo cha Tee kapena T - Chitsanzo kapena Z - Chitsanzo)
- 2). Chitsanzo cha ngodya
- 3). Kapangidwe ka Oblique (komwe kumadziwikanso kuti Kapangidwe ka Wye kapena Kapangidwe ka Y)
Zinthu zazikulu za valavu ya globe?
Kapangidwe kokhazikika (kapangidwe kowongoka)
Kapangidwe ka ngodya
Kapangidwe kokhazikika kokhala ndi chisindikizo cha bellows
- 1). Mtunda waufupi woyenda wa diski (sitiroko) pakati pa malo otseguka ndi otsekedwa,Ma valve a DIN-EN globendi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi;
- 2) .Good kusindikiza mphamvu
- 3). Pali mitundu yosiyanasiyana ya luso monga momwe imapezeka mu mawonekedwe wamba (mawonekedwe olimba), mawonekedwe a ngodya, ndi mawonekedwe a Wye (mawonekedwe a Y).
- 4). Valavu ya DIN-EN globe ingagwiritsidwe ntchito ngati valavu ya SDNR, valavu yowunikira dziko lonse mwa kusintha kapangidwe kake pang'ono.
- 5). Kukonza ndi kukonzanso mipando mosavuta, pazifukwa zosiyanasiyana.
Kuwongolera kapangidwe ka ma disc
Kulinganiza kapangidwe ka ma disc, DN200 ndi kupitirira apo

Chiwonetsero cha Zamalonda:
Kugwiritsa ntchito ma valve a globe
Valavu ya Globe imagwiritsidwa ntchito kwambiri muntchito zosiyanasiyana, zonse ziwiri, mphamvu yochepa komanso mphamvu yayikulu yamadzimadzi.
- 1). Madzi: Madzi, nthunzi, mpweya, mafuta osaphika ndi zinthu zopangidwa ndi mafuta, mpweya wachilengedwe, mpweya wozizira, njira zamakono, mpweya, mpweya wamadzimadzi ndi wosakwiya
- 2). Machitidwe ozizira a madzi omwe amafuna kudzipatula ndi kulamulira kayendedwe ka madzi.
- 3). Ma ventilator okhala ndi malo okwera komanso ma drain otsika.
- 4). Ma venti ndi mipope ya boiler, Ntchito za nthunzi, ma venti ndi mipope yayikulu ya nthunzi, ndi mipope ya heater.
