Description:

Slight resistance Non-return Backflow Preventer (Flanged Type) TWS-DFQ4TX-10/16Q-D – is a kind of water control combination device developed by our company, mainly used for water supply from urban unit to the general sewage unit strictly limit the pipeline pressure so that the water flow can only be one-way. Its function is to prevent the backflow of the pipeline medium or any condition siphon flow back, in order to avoid backflow pollution.

Characteristics:

1. It is of compact and short structure; slight resistance; water-saving (no abnormal drain phenomenon at the normal water supply pressure fluctuation); safe (in abnormal loss of pressure in the upstream pressure water supply system, the drain valve can be open timely, emptying, and the middle cavity of backflow preventer always takes precedence over the upstream in air partition); on-line detection and maintenance etc. Under normal work in economic flow rate, water damage of product designis 1.8~ 2.5 m.

2. Two levels check valve’ s wide valve cavity flow design is of small flow resistance, rapidly on-off seals of check valve, which can effectively prevent damages to the valve and pipe by sudden high back pressure, with mute function, effectively extending the service life of the valve.

3. Accurate design of drain valve, drain pressure can adjust the pressure fluctuation value of cut off water supply system, to avoid the interference of the system pressure fluctuations. On-off safely and reliably, no abnormal water leakage.

4. Large diaphragm control cavity design makes the reliability of the key parts is better than that of other backlow preventer, safely and reliably on-off for drain valve.

5. The combined structure of large diameter drain opening and diversion channel, complementary intake and drainage in the valve cavity have no drainage problems, completely limit the possibility of back down stream and siphon flow reversals occur.

6. Humanized design can be online test and maintenance.

Applications:

It can be used in harmful pollution and light pollution,for toxic pollution,it is also used if it cann’t prevent backflow by air isolation;
It can be used in source of branch pipe in harmful pollution and continuous pressure flow,and not used in preventing backlow of
toxic pollution.
