DN50-DN400 Slight Resistance Non-return Flanged Backflow Preventer Atin yang CE Certification a gewa keng China

Pamaglarawan:

Slight resistance Non-return Backflow Preventer (Flanged Type) TWS-DFQ4TX-10/16Q-D - metung yang uri ning water control combination device a gewa ning kekaming kumpanya, keraklan gagamitan para keng suplay ning danum ibat keng urban unit papunta keng general sewage unit mahigpit yang limitahan ing pressure ning pipeline para ing danum malyari yang metung a dalan. Ing obra na yapin ing pigilan ing pamagbalik ning pipeline medium o nanu mang kundisyun siphon flow back, para aiwasan ing pamagbalik ning polusyun.

Kaasalan:

1. Atin yang compact ampo makuyad a istruktura; ditak a pamaglaban; makatipid keng danum (ala yang abnormal a drain phenomenon keng normal a pamagbayu ning pressure ning suplay ning danum); ligtas (keng abnormal a pangawala ning pressure keng upstream pressure water supply system, ing drain valve malyari yang makabuklat keng oras, mag-empty, ampo ing libutad a cavity ning backflow preventer parati yang mumuna kesa keng upstream keng air partition); on-line detection ampo maintenance etc. keng normal a obra keng economic flow rate, ing pangasira ning danum keng product designis 1.8~ 2.5 m.

2. Adwa lang antas ning check valve's wide valve cavity flow design na ning malating flow resistance, mabilis a on-off seals ning check valve, na epektibung makaiwas keng pangasira ning valve ampo ing pipe kapamilatan ning biglang matas a back pressure, a maki mute function, epektibung makapalawig keng service life ning valve.

3. Ustu ing disenyu ning drain valve, ing drain pressure malyari yang mag-adjust keng pressure fluctuation value ning cut off water supply system, para aiwasan ing interference ning system pressure fluctuations. On-off ligtas at mapanalig, alang abnormal a pamagtagas ning danum.

4. Ing maragul a diaphragm control cavity design gagawan na ing reliability da reng key parts mas masanting ya kesa kareng aliwang backlow preventer, ligtas at reliable on-off para keng drain valve.

5. Ing metung a istruktura ning maragul a diametru ning drain opening ampo ing diversion channel, ing complementary intake ampo ing drainage keng valve cavity ala lang problema keng drainage, lubus dang lilimitan ing posibilidad ning pamagbalik keng stream ampo ing siphon flow reversals.

6. Ing humanized design malyari yang online test ampo maintenance.

Applications:

Malyari yang gamitan keng makasumami a polusyun ampo polusyun keng sala, para keng makalasun a polusyun, magagamit ya naman nung e na agyung pigilan ing pamagbalik ning danum kapamilatan ning pamag-isolate keng angin;
Malyari yang gamitan bilang panibatan ning branch pipe keng makasumami a polusyun ampo patuloy a dagul ning pressure, at ali ya gamitan keng pamag-iwas keng backlow ning
makalasun a polusyun.
