Triple function, large air exhausting, small air venting, vacuum breaker, Anti-shock, Combination air release valve
Features:
. Advanced design with simple mechanism, strong fl oat to prevent cracking during sudden water hammer& quick closure.
. Aerokinetic mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
. No arms or levers to prevent vibrating, bending, direct closure of the fl oat.
. Smooth cage outside of the fl oat, keep float moving in specifi ed guide rail.
. Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
. Outside screen will be an option for safety and prevent insects or birds in.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard meets BS EN1074-4, AWWA C512
. Flange drilling and dimension meets BS EN 1092 and BS EN 558 and ANSI flange.
Function:
Combination kinetic air release valve provide 3 functions:
1. Large air release
1-1. During filling the pipeline, float will stay at its original position. (open)
1-2. Let large air out of valve thru big nozzle.
2. Small air release
2-1.When the water level comes up to the top, float will be up to its close position and close the sealing arc- big orifice and small orifice.
2-2.The air (2% of solved air in water ) are continuously coming out from water and gather at the top of the valve.
2-3.The float will be driven down and let small pocket out thru small orifice.
2-4.The sealing arc will still be in close position until empty of water
3. Large air intake during draining of the pipeline.
3-1.Float will drop down when empty of pipeline.
3-2.Large air will come into the pipeline thru valve.
3-3.Preventing from collapse of pipeline and break vacuum.
3-4.Protect the sealing o-ring from clogging in the pipeline.
Service Fields:
For water system, fire fighting, irrigation system.
