Why use a three prevention check valve? At present, all kinds of check valves in use (including multi-function control type check valves), especially the "check valve relying on spring force", have not only failed in the check effect after long-term use, but also have large water loss and increased water and energy consumption due to the existence of springs and extreme reduction of the valve diameter. If the water company replaces other types of products with "loose knot three-prevention valve"on a large scale, it can greatly save energy consumption.
The "three prevention valve" is designed to be installed behind the water meter to ensure accurate measurement of the water meter.
Explanation of Three-Prevention
First prevention:
Anti-rotation→water meter rotates without water flowing.
Second prevention:
Anti-dripping (improving the sensitivity of the water meter)→the problem of non-metering of the water meter due to the phenomenon of "running, emitting dripping and leaking”.
Third prevention:
Anti-backflow (anti-pollution partition)→sewage and hot water device flow Backflow.

Installation and use suggestion:
In order to ensure the accurate measurement of the water meter, the "three prevention valve" is designed to be installed behind the water meter (replace one pipe joint behind the meter).
