High Quality Industrial SDNR valavu padziko lonse China fakitale supplier Wopanga
Kodi valavu yapadziko lonse ya SDNR ndi chiyani?
SDNR valavu yapadziko lonse lapansiidapangidwa ndikupangidwa molingana ndi muyezo wakale waku Germany, DIN komanso masiku ano muyeso waku Europe EN13709.imagwiritsidwa ntchito kwambiri m'maiko a European Union.
valavu yotseka-pansi yozungulira yomwe imagwiritsidwa ntchito poyambira, kuyimitsa kapena kuyendetsa kayendedwe kake pogwiritsa ntchito membala wotseka wotchedwa disc.Kutsegula kwa mpando kumasintha mofanana ndi kuyenda kwa chimbale chomwe ndi choyenera kwa ntchito zokhudzana ndi kayendetsedwe ka kayendetsedwe kake.ma valve a DIN-EN Globe ndi abwino kwambiri komanso amagwiritsidwa ntchito kwambiri kuwongolera kapena kuyimitsa kutuluka kwamadzi kapena gasi kudzera papaipi kuti ayendetse ndikuwongolera kutuluka kwamadzimadzi ndipo nthawi zambiri amagwiritsidwa ntchito pamapaipi ang'onoang'ono.
ndiSDNR valavu yapadziko lonse lapansiItha kugwiritsidwa ntchito pazifukwa zopukutira komanso.Matupi ambiri okhala ndi ma valve okhala ndi amodzi amagwiritsa ntchito khola kapena zomangamanga kuti asungire mphete yapampando, kupereka chiwongolero cha pulagi ya valavu, ndikupereka njira zokhazikitsira mawonekedwe enaake oyenda valavu.Zingathenso kusinthidwa mosavuta ndi kusintha kwa zigawo zochepetsera kuti zisinthe mawonekedwe othamanga kapena kupereka kuchepa kwa mphamvu, kuchepetsa phokoso, kapena kuchepetsa kapena kuthetsa cavitation.
nthawi zambiri pali mitundu itatu yoyambira ya thupi kapena mapangidwe akeSDNR valavu yapadziko lonse lapansi:
- 1).Standard Pattern (komanso Tee Pattern kapena T - Pattern kapena Z - Pattern)
- 2).Oblique Pattern (yomwe imadziwikanso kuti Wye Pattern kapena Y - Pattern)
Zina zazikulu za valavu yapadziko lonse ya SDNR?
Chitsanzo chokhazikika (chitsanzo chowongoka)
Chitsanzo cha ngodya
Standard chitsanzo ndi bellows chisindikizo
- 1) mtunda waufupi woyenda wa disc (stroke) pakati pa malo otseguka ndi otsekedwa,DIN-EN mavavu a globendi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa kawirikawiri;
- 2).Kukwanitsa kusindikiza bwino
- 3) .Pali mitundu yosiyanasiyana ya kuthekera komwe ikupezeka muzochita zofananira (kuwongolera), pateni ya ngodya, ndi mtundu wa Wye (Y pattern).
- 5) .Easy Machining ndi resurfacing wa mipando, pa zolinga zosiyanasiyana.
- 6) .Moderate mpaka wabwino throttling mphamvu, mwa kusintha kamangidwe ka mpando ndi chimbale.
- 7) Amagwiritsidwa ntchito kwambiri m'maiko onse a European Union, ndi mayiko enanso.
- 8) .Bellows chisindikizo chikupezeka pa pempho.
Kuwongolera kapangidwe ka disc
Kusanja chimbale kapangidwe, DN200 ndi pamwamba
