ZDL Series Automatic recirculation control valve
ZDL yakatevedzana Auromatic recirculation valve imhando yepombi prtectiong mudziyo. It otomatiki inodzivirira 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 kuyerera kuyerera i zero, iyo shoma inoyerera inogona zvakare kupfuura nekupfuura yeOtomatiki recirculation. Dzvinyiriro yakaderedzwa kuburikidza nemultistage bypass pressure yekudzikisa valve. ZDL yakatevedzana inokodzera bypass ine yepakati kana yakaderera kudzvinyirira musiyano, yakanyanya kudzvanywa musiyano i6MPa, uye yakasarudzika sarudzo inotemerwa fekitori. Yakasarudzika L bypass inogona kubvisa ruzha neyakagadzirwa yakakwira-spped flow medium, uye precent cavitation.
• Multi-cage type bypass, yakaderera ruzha, yakakodzera yepakati uye yakaderera kumanikidza kushanda mamiriro.
• Forged valve body, inogona kusarudza carbon steel kana Stainless steel material, nezvimwewo.
• Standard bypass isiri kudzoka fuction, yakanyanya kushanda kudzvanywa kusiyanisa ndeye 6MPa.
• Ne venturi port main flow non-return structure, shandura kumamiriro ezvinhu akaoma.
• Pressure giredhi kubva PN16 kusvika PN100, dhayamita kubva DN2 kusvika DN500.
• Inogona kusarudza manual bypass operation function, inoshandiswa mukukanganisa.
Valve body type: Muviri wakagadzirwa nzira nhatu.
Zita dhayamita: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Nominal pressure: CL150#-600# (PN16, 25, 40, 64, 100)
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 inosarudzika.
• Special bypass size inogona customized. Iwo max kuyerera mwero we bypass ari pasi pehukuru hwe Kv.
