Mini Backflow Preventer

Description:

Most of the residents don't install the backflow preventer in their water pipe. Only a few people use the normal check valve to prevent back-low. So it will have a big potential ptall. And the old type of backflow preventer is expensive and not easy to drain. So it was very hard to be widely used in the past. But now, we develop the new type to solve it all. Our anti drip mini backlow preventer wil be widely used in the normal user. This is a waterpower control combination device through control the pressure in the pipe to come true the one-way flow. It wil prevent back-flow, avoid the water meter inverted and anti drip. It will guarantee safe drinking water and prevent the pollution.

Characteristics:

1. Straight-through sotted density design, low flow resistance and low noise.
2. Compact structure, short size, easy instal lation, save installing space.
3. Prevent water meter inversion and higher anti-creeper idling functions,
drip tight is helpful to water management.
4. Selected materials have long service life.

Working Principle:

It is made up of two check valves through the threaded
connection.
This is a waterpower control combination device through control the pressure in the pipe to come true the oneway flow. When the water comes, the two discs will be open. When it stops, it will be cloosed by its spring. It will prevent back-flow and avoid the water meter inverted. This valve has another advantage: Guarantee the fair between the user and Water Supply Corporation. When the flow is too small to charging it( such as: ≤0.3Lh),this valve will solve this condition. According to the change of water pressure, the water meter turns.
Installation:
1. Clean up the pipe before the insalation.
2. This valve can be installed in horizontal and vertical.
3. Ensure the medium flow direction and the direction of arrow in the same when install.
