DEYE ikumvetsa udindo wofunikira womwe kusankha ma valavu kumachita pakugwira ntchito bwino komanso kudalirika kwa kuchotsa mchere m'madzi a m'nyanja ndi madzi amchere. Ma valavu ndi ofunika kwambiri.

zigawo zomwe zili mu makina zomwe ziyenera kupirira dzimbiri la mchere wambiri, kusiyana kwa kuthamanga kwamphamvu, ndi kugwira ntchito kosalekeza. Kusankha valavu yoyenera

Zimathandiza kuti ntchito yokonza madzi a m'nyanja iyende bwino kwambiri ngakhale pamavuto.

Gulugufe Watatu wa DEYE Ma valve amagwiritsa ntchito luso lapamwamba kumapeto kwa kulumikizana, ndi mphamvu yochepa yogwiritsira ntchito ma valve. Ndi oyenera kwambiri ma actuator apadziko lonse lapansi, zomwe zimathandiza kuti pakhale kuyika kosavuta pamalopo komanso kusunga ndalama kwa actuator. kusankha.

Ma valve okhala ndi shaft yotambasulidwa ndi chisankho chabwino kwambiri cha ma valve omwe amayikidwa pansi pa nthaka. Ndi ofunikira kwambiri pamakina amakono opachikira mapaipi.

 Tsinde lotambasulidwa nthawi zambiri limafunsa zinthu monga momwe zilili pansipa

• Kutalika kwapadera (nthawi zambiri 1–6m, mpaka 10+m) pa kuya kwa manda.
• Kutalika kwa telescopic / kosinthika (±100mm).
• Kuwongoka kwambiri (≤0.1mm/m) ndi mphamvu yoletsa kupindika.
• Manja a DI okhala ndi zokutira zotsutsana ndi dzimbiri (zinc + epoxy, ≥80mm) kapena Manja a PVC.
• Zinthu Zopangira Tsinde: 2Cr13、304/316、410, Chitsulo chokhala ndi Zinc.

Akatswiri ogula zinthu ndi oyang'anira mapulojekiti akamafunafuna kampani yodalirika yopangira ma valve ku China — yomwe imatha kupereka ma valve ovomerezeka, okonzedwa m'magawo osiyanasiyana oyeretsera madzi, mafuta ndi gasi, za m'madzi, ndi mafuta — miyeso yoyenerera imakhala yapamwamba kwambiri. Sangofuna wogulitsa zinthu zokha, komanso mnzake waukadaulo wokhala ndi ziphaso zotsimikizika, chidziwitso chamakampani ambiri, komanso mphamvu zamkati kuti athe kuthana ndi zofunikira zovuta zamakina a mapaipi kuyambira pa zofunikira mpaka kutumiza. Shijiazhuang Deye Piping Industry Co., Ltd. (DOYES VAVLE) ndiye mnzake weniweniyo, yemwe amagwira ntchito pamapulojekiti apadziko lonse lapansi okhala ndi zinthu zambiri, zomangamanga zopangira mafakitale awiri, komanso njira yowongolera khalidwe yomangidwa motsatira miyezo yapadziko lonse lapansi.

Ngati valavu ikufunika kuyikidwa pamalo okwera, kugwira ntchito yotsegula ndi kutseka ndi dzanja sikophweka komanso koopsa. Mavalavu okhala ndi unyolo wa chainwheel adzakhala chisankho chofunikira, amapangidwa makamaka kuti mavalavu oyikidwa pamalo okwera ndipo amawongoleredwa ndi unyolo (unyolo woyendetsedwa ndi dzanja) Kuti mutsegule ndi kutseka valavu, gawo lalikulu logwirira ntchito ndi bokosi la gearbox loyendetsedwa ndi unyolo kapena bokosi la gearbox la bevel. Ntchito yake yayikulu ndikuchepetsa liwiro ndikuwonjezera mphamvu, zomwe zimathandiza ogwiritsa ntchito kutsegula ndi kutseka mosavuta mavavu akuluakulu omwe ali pamalo okwera kuchokera pansi.

Deye Piping Industry Co., Ltd ndi katswiri wopanga komanso wogulitsa ma valve a plunger (valvu yowongolera kuyenda ndi kuthamanga) , tikhoza kupanga kukula kwa valavu ndikupereka lingaliro labwino kwambiri malinga ndi pempho lanu la mphamvu yogwirira ntchito komanso kufunikira kwa kutsika kwa mphamvu. Vavu ya plunger ili ndi mphamvu yabwino yowongolera mphamvu yoyenda ndi kutsika kwa mphamvu. Imatha kuwongolera kuyenda bwino, kugawa kutsika kwa mphamvu, ndikuletsa kutsekeka kwa cavitation ndi phokoso pakakhala kusiyana kwakukulu kwa mphamvu. Imagwiritsidwa ntchito kwambiri mu kayendetsedwe ka boma, kusamalira madzi, ndi mafakitale, ndipo ndi chisankho chabwino kwambiri cha valavu yowongolera madzi molondola kwambiri.

Pansipa pali kutumiza kwatsopano kwa valavu ya singano ya plunger kupita ku Europe, Class 300 DN900 Kupanikizika kogwira ntchito ngati PN50, ndi kupanikizika Drop 40bar, njira yotulutsira yokhala ndi zingwe zopangidwa kuti zithetse kutsekeka kwa cavitation.

Ufa wa Epoxy Wokutidwa mkati ndi kunja.

Valavu ya Gulugufe ya Triple Offset yokhala ndi Epoxy Powder Coated yovomerezeka ndi WRAS, yomwe imalola mainjiniya kusankha ukadaulo wodalirika komanso wotseka madzi wamadzi ofunikira kwambiri—madzi akumwa—ndi chidaliro chonse mu chitetezo chake, kulimba kwake, komanso kutsatira malamulo ake. Ndi chisankho chotsimikizika cha mains otumizira madzi amphamvu, malo olekanitsira ofunikira, ndi madzi a mafakitale komwe kulephera si njira ina.TOBV ndi mtundu wapamwamba wa valavu ya gulugufe yomwe idapangidwa kuti ichotse kukangana ndi kuwonongeka komwe kumachitika ndi mavalavu a gulugufe achikhalidwe. Zinthu zake zazikulu ndi izi:

C5 anti-corrosion ndi salt spray rating ndi muyezo wapadziko lonse wokhudzana ndi chitsulo pamwamba pake komanso anti-corrosion, womwe umagwiritsidwa ntchito kwambiri poyesa kukana dzimbiri kwa zinthu zachitsulo m'malo ovuta. Ma valve okhala ndi C5 anti-corrosion ndi salt spray grade nthawi zambiri amagwiritsidwa ntchito pazinthu zachitsulo ndi zida m'mafakitale monga m'madzi, m'mphepete mwa nyanja, m'mafakitale amafuta, ndi m'mafakitale a mankhwala omwe amafunikira kwambiri anti-corrosion.

Ma valve oyezera nozzle otchedwanso axial flow check ndi ofunikira kwambiri. Chofunika kwambiri pa ntchito yosabwezera madzi, osagundana komanso kutseka mwachangu

makhalidwe.

Ma valve achitsulo chosapanga dzimbiri, ma valve achitsulo chosapanga dzimbiri, ndi ma valve a Hastelloy amagwiritsidwa ntchito m'malo osiyanasiyana okhala ndi dzimbiri kwambiri, komanso malo ogwirira ntchito ovuta. Ma valve achitsulo chosapanga dzimbiri amagwiritsidwa ntchito makamaka m'makampani opanga mafuta, makampani a ukhondo komanso nthawi zina madzi a zimbudzi okonzedwa bwino a TSE, Duplex Chitsulo chosapanga dzimbiri makamaka ndi cha madzi a m'nyanja. Ma valve a Hastelloy amagwiritsidwa ntchito pochiza dzimbiri kwambiri komanso kutentha kwambiri komanso kuthamanga kwambiri.
