ZDM Series Automatic recirculation control valve
ZDM akatevedzana otomatiki recirculation vharafu imhando yepombi yekudzivirira mudziyo. Iyo otomatiki inodzivirira centrifugal pombi kana pombi yemuviri ikaitika cavitation inokuvadza kana isina kugadzikana (kunyanya kuendesa mvura inopisa pakushanda kwakaderera). Kamwe pombi yekuyerera yakadzikira pane kuyerera kwakagara kwagara, bypass inogona kuvhurika zvachose kuti ive nechokwadi chepasi chinodiwa chekuyerera pombi. Kunyangwe ichimhanya yakavharwa zvakazara, kureva kuyerera kuyerera i zero, iyo shoma inoyerera inogona zvakare kupfuura nekupfuura yeOtomatiki recirculation. Dzvinyiriro yakaderedzwa kuburikidza nemultistage bypass pressure yekudzikisa valve.
ZDM yakatevedzana inokodzera bypass ine yakanyanya kudzvanywa musiyano, yakanyanya kudzvanywa musiyano ndeye 30MPa, uye chaiyo sarudzo inotemerwa fekitori. Multistage decompression type M type bypass inogona kubvisa ruzha rwakaitwa nehupamhi hwekuyerera kwepakati, kudzivirira kukuvadzwa kwecavitation erosion uye braising kune zvikamu zvevharuvhu.
• Kudzivirira cavitation multistage decompression bypass, kuderedza velocity, yakakodzera kune yakakwirira kudzvinyirira mamiriro.
• Forged valve body, kana unogona kusarudza carbon steel kana Stainless steel material, etc.
• Standard bypass isiri-kudzoka basa, yakanyanya kushanda kudzvinyirira musiyano ndeye 30MPa.
• Pressure giredhi kubva PN16 kusvika PN420, dhayamita kubva DN2 kusvika DN500.
• Inogona kusarudza manual bypass operation function, inoshandiswa mukukanganisa.
Valve body type: Three-way forged valve
Zita dhayamita: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Nominal pressure: CL150#-2500# (PN16, 25, 40, 64, 100, 160, 250, 420)
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.
• Bypass multistage pressure kuderedza: bypass control system inogona kuderedza backflow medium kubva pahigh-pressure pump outlet kuenda kubackflow kwakakodzera kusvika kune yakaderera-pressure storage device ine ruzha rushoma kupfeka.
• Tarisa: Otomatiki recirculation vharafu inewo cheki chevhavha mhedzisiro, ichidzivirira iyo mvura yekudzokera kumashure kupomba muviri. Bypass isingadzoke basa iri mwero.
• Special bypass size inogona customized. Iwo max kuyerera mwero we bypass ari pasi pehukuru hwe Kv.
