ZDT mndandanda Automstic recirculation valve ndi mtundu wa chipangizo choteteza pampu. Iwo basi kuteteza centrifugal mpope pamene mpope thupi zimachitika cavitation kuwonongeka kapena kusakhazikika (makamaka kunyamula madzi otentha pa otsika katundu ntchito). Kuthamanga kwa pampu kukakhala kocheperako kuposa momwe adakhazikitsira, bypass imatha kutseguka kuti iwonetsetse kuti pampu yoyenda ikufunika. Ngakhale kuthamanga kutsekedwa kwathunthu, ndiko kuti kutuluka kwakukulu ndi ziro, kuyenda kochepa kungathenso kutuluka kuchokera panjira.

Mndandanda wa ZDT uli ndi zodutsa zazikulu, ndipo valavu iyi ndi yoyenera kudutsa ndi kutuluka kwakukulu, kusiyana kwakukulu kwapakati ndi 4MPa, kusankha kwapadera kumatsimikiziridwa ndi fakitale.

Makhalidwe

• Kapangidwe kosavuta, ntchito yodalirika komanso yokhazikika, yokhala ndi magawo ochepa oyenda.
• Khalani zosavuta unsembe, akhoza kuikidwa vertically kapena horizontally pa mpope kubwereketsa.
• Kuthamanga kwa Bypass ndi kwakukulu, kuthamanga kwakukulu ndi 60% ya kutuluka kwakukulu, valve ya KV ikhoza kusinthidwa.
• Kuthamanga kwapang'onopang'ono kodutsa ndi 4MPa. Ntchito yosabwereranso yobweza ndiyosasankha.
• Sing'anga yogwiritsidwa ntchito kuphatikiza: madzi, mafuta, methanol ndi sing'anga ina yamadzimadzi.
• Kutentha kwa ntchito: -196 ℃ mpaka +130 ℃.

Diameter ndi osiyanasiyana kuthamanga

Mtundu wa thupi la vavu: valavu yoponyera njira zitatu

M'mimba mwake mwadzina: NPS1"-16" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400)

Kupanikizika mwadzina: CL150#-400# (PN16, 25, 40, 64)

Mapeto amtundu wa kulumikizana: Flange FF, RF, RTJ, BW, SW, etc.

Mfundo yogwira ntchito

Malingana ndi kusiyana kwa kutuluka kwakukulu kwa inductive, valavu yayikulu yoyang'ana valavu yodziwikiratu imasunthira kumalo enaake. Panthawi imodzimodziyo, tsinde la valve disk drive bypass valve, sinthani kayendedwe ka valve yaikulu kuti idutse, kupyolera mu ulamuliro wa bypass valve disc, kusintha malo ozungulira, kuti muwongolere kutuluka. Pamene valavu yayikulu imabwerera kumpando wa valve yatsekedwa, zonse zimabwerera mmbuyo kupyolera mu bypass. Pamene chimbale chachikulu cha vavu chikwera pamwamba, chodutsacho chimatsekedwa kwathunthu, kutuluka konse kwa mpope kupita ku dongosolo. Vavu iyi imayika ntchito zinayi m'thupi limodzi.

• Lingaliro lakuyenda: Ma valve main valve disc amatha kuzindikira momwe kayendedwe ka kayendedwe kake kamayendera, potero molingana ndi kayendedwe kake kuti adziwe malo a valavu yayikulu ndi disc disc.
• Kuwongoleranso: Vavu yodziyimira payokha imatha kutulutsa mpope momwe ntchito yanthawi zonse imafunikira kuyenda pang'onopang'ono mu chipangizo chosungiramo kudzera panjira yodutsa, kuti musinthe mawonekedwe a pampu ya HQ, kuti azindikire kubwezeretsanso.
• Yang'anani valavu: Valavu yodziyimira yokha imakhalanso ndi cheke valavu, kuteteza kubweza kwamadzi kuti ipope thupi. Ntchito yosabwereranso yobweza ndiyosasankha.
• Special kulambalala kukula akhoza makonda. Kuthamanga kwakukulu kodutsa kumatengera Kv mtengo.
