DN50-DN400 Slight Resistance Non-return Flanged Backflow Preventer Walay CE Certification ya ginawa ed China

Deskripsyon:

Say Slight resistance Non-return Backflow Preventer (Flanged Type) TWS-DFQ4TX-10/16Q-D - et sakey a klase na water control combination device ya ginawa na kompanya mi, ya manunan uusaren parad suplay na danum manlapud urban unit ya anggad general sewage unit ya malet ya limitaan so presyon na tubo pian say agos na danum et nayarin onla labat ed sakey a dalan. Say gagala to et pian naprebentaan so backflow na pipeline medium odino antokaman a kondisyon na siphon flow back, pian napaliisan so backflow pollution.

Saray pakabidbiran:

1. Saya et masimpit tan antikey so istruktura to; daiset ya onsusumpa; makatipid na danum (anggapoy abnormal ya drain phenomenon ed normal ya pananguman na presyon na danum); ligtas (diad abnormal ya pakawalaan na presyon ed upstream pressure water supply system, say drain valve et nayarin nalukasan ed dugan panaon, man-empty, tan say pegley na cavity na backflow preventer et lanang ya mas importante nen say upstream diad air partition); on-line detection tan maintenance tan arum nira. Diad normal ya trabaho ed economic flow rate, say pakaderal na danum ed desinyo na produkto et 1.8~ 2.5 m.

2. Say duaran lebel na check valve's wide valve cavity flow design et walaan na melag ya flow resistance, maples ya on-off seals na check valve, ya epektibon makaamper ed pakaderal na balbula tan tubo lapud biglan atagey ya back pressure, ya walay mute function, ya epektibon mamalaknab na serbisyo na balbula.

3. Say suston desinyo na drain valve, say drain pressure et makapangi-adjust na pressure fluctuation value na cut off water supply system, pian napaliisan so interference na pressure fluctuations na sistema. On-off ya ligtas tan napanmatalkan, anggapoy abnormal ya itatagey na danum.

4. Say baleg ya desinyo na diaphragm control cavity et manggagawa ed saray manunan parte ya mas maong nen say arum ya backlow preventer, ya ligtas tan napanmatalkan ya on-off parad drain valve.

5. Say nankakasakey ya istruktura na baleg a diametro na drain opening tan diversion channel, say komplementaryon intake tan drainage ed valve cavity et anggapoy problema ed drainage, sigpot ya manlimitad posibilidad na back down stream tan siphon flow reversals.

6. Say humanized design et nayarin online test tan maintenance.

Aplikasyon:

Nayarin usaren iya ed makaderal a polusyon tan polusyon ed liwawa, parad makasamal a polusyon, nausar met iya no agto naprebentaan so backflow panamegley na air isolation;
Nayarin usaren iya bilang panlapuan na sanga na tubo ed makaderal a polusyon tan tuloytuloy ya iyaagus na presyon, tan ag-itan usaren ed pangisebel ed backlow na
makasamal ya polusyon.
