DIN-EN Globe Valve
Kodi valavu yapadziko lonse ya DIN-EN ndi chiyani?
DIN-EN Globe valveidapangidwa 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 kayendetsedwe 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.
ndiDIN-EN Mavavu a GlobeItha 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.
ma valve a DIN-EN globe amathanso kusinthidwa ngati valavu yoyang'ana padziko lonse lapansi, SDNR (yosabwerera pansi), ndi ntchito zonse za valavu yapadziko lonse lapansi ndi valavu yowunika (valavu yosabwerera).chifukwa chazovuta komanso zovuta zogwirira ntchito, chisindikizo cha bellows chimapezekanso mukapempha.
nthawi zambiri pali mitundu itatu yoyambira ya thupi kapena mapangidwe akeDIN-EN Mavavu a Globe:
- 1).Standard Pattern (komanso Tee Pattern kapena T - Pattern kapena Z - Pattern)
- 2)
- 3).Oblique Pattern (yomwe imadziwikanso kuti Wye Pattern kapena Y - Pattern)
Zina zazikulu za valavu yapadziko lonse ya DIN-EN?
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).
- 4) .Vavu ya globe ya DIN-EN ingagwiritsidwe ntchito ngati valavu ya SDNR, valavu yoyang'ana padziko lonse posintha mapangidwe pang'ono.
- 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 likupezeka pa pempho.
Kuwongolera kapangidwe ka disc
Kusanja chimbale kapangidwe, DN200 ndi pamwamba
