ZDT Model Automatic recirculation control valve
ZDT yakatevedzana Automstic recirculation valve imhando yepombi yekudzivirira mudziyo. It otomatiki kudzivirira centrifugal pombi kana pombi muviri kuitika cavitation kukuvara kana kusagadzikana (kunyanya kuendesa mvura inopisa panguva yakaderera mutoro kushanda). Kamwe pombi yekuyerera yakadzikira pane kuyerera kwakagara kwagara, bypass inogona kuvhurika zvachose kuti ive nechokwadi chepasi chinodiwa chekuyerera pombi. Kunyangwe ichimhanya yakavharwa zvakazara, kureva main flow i zero, iyo shoma inoyerera inogonawo kubuda kubva pabypass.
ZDT yakatevedzana ine hombe yekubvongodza, uye iyi vharuvhu inokodzera bypass nekuyerera kukuru, yakanyanya kudzvanywa musiyano ndeye 4MPa, chaiyo sarudzo inotarwa nefekitori.
• Chimiro chakareruka, kushanda kwakavimbika uye kwakagadzikana, nezvikamu zvishoma zvekufamba.
• Iva nyore kugadzika, inogona kuiswa yakatwasuka kana yakatwasuka pane pombi inobuda.
• Bypass inoyerera yakakura, yakawanda inoyerera ndeye 60% yekuyerera kukuru, KV valve inogona kugadziriswa.
• Maximum bypass operating pressure differential is 4MPa. Bypass isingadzoke basa inosarudzika.
• Inoshandiswa svikiro inosanganisira: mvura, mafuta, methanol uye imwe mvura yepakati.
• Kushanda tembiricha: -196 ℃ kusvika +130 ℃.
Valve body type: three-way casting valve
Zita dhayamita: NPS1"-16" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400)
Nominal pressure: CL150#-400# (PN16, 25, 40, 64)
End yekubatanidza mhando: Flange FF, RF, RTJ, BW, SW, nezvimwe.
Zvinoenderana nemusiyano we inductive main flow, main valve disc cheki koni yeotomatiki recirculation vharafu inongoenda kune imwe nzvimbo. Panguva imwe chete iyo huru yevhavha disc drive bypass valve stem, fambisa mafambiro evharuvhu disc kuti anyenyeredze, kuburikidza nekudzora bypass valve disc chinzvimbo, shandura bypass throttling nzvimbo, kuitira kudzora bypass kuyerera. Kana vharuvhu huru ichidzokera muchigaro chevharuvhu yakavharwa, ese anoyerera achidzokera nekupfuura. Kana guru vharuvhu disc kukwira kumusoro chinzvimbo, bypass yakanyatsovharwa, kuyerera kwese kwepombi kuyerera kune process system. Iyi vharuvhu inoisa mabasa mana mumuviri mumwe.
• Maonero ekuyerera: Otomatiki recircution valve main valve disc inogona kuona otomatiki kuyerera kukuru kwemaitiro system, nekudaro zvinoenderana nekuyerera kuti uone nzvimbo yevhavha huru disc uye bypass disc.
• Recirculation control: Otomatiki recirculation vharafu inogona inhaled pombi yakajairika kushanda kunodiwa kushoma kuyerera muchichengetera mudziyo kuburikidza bypass, kuitira kugadzirisa pombi HQ charateristics, kuona recycling.
• Chengetedza vharafu: Otomatiki recirculation vharafu zvakare ine cheki chevhavha mhedzisiro, ichidzivirira iyo mvura yekudzokera kumashure kunopomba muviri. Bypass isingadzoke basa inosarudzika.
• Special bypass size inogona customized. Iwo max kuyerera mwero we bypass ari pasi pehukuru hwe Kv.
