ZDL Series Automatic recirculation control valve
Letoto la ZDL Auromatic recirculation valve ke mofuta oa sesebelisoa sa pompo ea prtectiong. E sireletsa pompo ea centrifugal ka mokhoa o itekanetseng ha 'mele oa pompo o etsahala tšenyo ea cavitation kapa e sa tsitsang (haholo-holo ho tsamaisa metsi a chesang ka ts'ebetso e tlaase ea mojaro). Hang ha phallo ea pompo e le tlase ho feta phallo e reriloeng, bypass e ka buleha ka botlalo ho netefatsa pompo ea phallo e hlokahalang. Esita le ho matha ho koetsoe ka botlalo, e leng ho phalla ha metsi ke zero, phallo e fokolang e ka boela ea feta bakeng sa Automatic recirculation. Khatello e fokotsehile ka valve ea ho fokotsa khatello ea multistage bypass. Letoto la ZDL le loketse ho feta ka phapang e mahareng kapa e tlase ea khatello, phapang e phahameng ea khatello ke 6MPa, mme khetho e ikhethileng e khethoa ke feme. Unique L bypass e ka felisa lerata ka ho etsa phallo e phahameng haholo, le precent cavitation.
• Multi-cage type bypass, lerata le tlaase, le loketseng maemo a ho sebetsa a mahareng le a tlaase.
• 'Mele oa li-valve o entsoeng, o ka khetha tšepe ea carbon kapa thepa e sa hloekang, joalo-joalo.
• Fuction e tloaelehileng ea bypass e sa khutleng, phapang e phahameng ea khatello ea ho sebetsa ke 6MPa.
• Ka sebopeho se seholo sa phallo ea venturi port e sa khutliseng, ikamahanya le maemo a thata.
• Kereiti ea khatello ho tloha ho PN16 ho ea ho PN100, bophara ho tloha ho DN2 ho ea ho DN500.
• E ka khetha tšebetso ea opereishene ea bypass, e sebelisoang ka phoso.
Mofuta oa 'mele oa li-valve: 'mele o entsoeng ka litsela tse tharo.
Bophara ba lebitso: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Khatello ea lebitso: CL150#-600# (PN16, 25, 40, 64, 100)
Mofuta oa khokahanyo ea ho qetela: Flange, FF, RF, RTJ, BW, SW joalo-joalo.
Ho ea ka phapang ea phallo e kholo ea inductive, mochini o ka sehloohong oa li-valve tsa ho hlahloba li-valve tsa othomathike o tla fallela sebakeng se itseng. Ka nako e ts'oanang, thipa ea "valve" e ka sehloohong ea "valve" ea "valve" e fetisang motsamao oa "valve" ea "valve" ho feta, ka taolo ea "bypass valve", e fetola sebaka sa "bypass throttling", e le ho laola phallo ea bypass. Ha li-valve tse kholo li khutlela setulong sa valve se koetsoe, tsohle li phalla ka morao ka tsela e fetang. Ha li-valve tse kholo tsa disc li nyolohela sebakeng se ka holimo, bypass e koetsoe ka ho feletseng, phallo eohle ea phallo ea pompo ho ea tsamaisong. Belofo ena e behile mesebetsi e mene 'meleng o le mong.
• Maikutlo a phallo: Li-valve tse kholo tsa li-valve tsa li-valve li ka lemoha ka ho toba phallo e kholo ea tsamaiso ea ts'ebetso, ka tsela eo ho ea ka phallo ho fumana sebaka sa "valve" e kholo le "bypass disc".
• Taolo ea ho potoloha hape: Valofo ea ho potoloha e iketsang e ka hema pompo e tloaelehileng ea ts'ebetso e hlokahalang hore bonyane phallo e kene ka har'a sesebelisoa sa polokelo ka bypass, e le ho lokisa liphatlalatso tsa pompo ea HQ, ho hlokomela ho sebelisoa hape.
• Ho fokotsa khatello ea methati e mengata ea Bypass: Sisteme ea taolo ea bypass e ka fokotsa sekhahla sa ho khutla ho tloha setsing sa pompo se nang le khatello e phahameng ho ea ho sesebediswa sa polokelo se nang le khatello e tlase se nang le lerata le lenyenyane.
• Hlahloba: Li-valve tsa ho khutlisetsa li-automatic li boetse li na le phello ea ho hlahloba li-valve, e thibelang ho phalla ha metsi ho pompa 'mele. Mosebetsi oa ho se khutlele oa Bypass ke oa boikhethelo.
• Special bypass boholo ka customized. Sekhahla se phahameng sa phallo ea bypass se ipapisitse le boleng bo phahameng ba Kv.
