Flap valves tide against flooding
Why say Flap valve flooding-resistant?
First we need to understand the flooding is due to two main factors: the rain and flood tide rises.
When heavy rain phenomenon occurs, a large volume of water need to be bailed out of canals Lake River as fast as possible to avoid flooding, stagnant. To accomplish this, the system must function properly designed capacity, implementation. However in fact every chance to escape system always works not all design capacity, one of the main reasons is due to the congestion by offsets the penetration of the object or the tide water infiltration inside conversely offsets.
Thus, should the role of the Court against the stop valves flooded very necessary and important. Stop valves the Court acts to protect the drain exit from tidal water infiltration to the contrary in the drain and garbage, object entered in the storm drain causing congestion, help for storm drain information always escape full design capacity, help increase resistance to flooding. The valve prevents the Court not directly related to the sewer but have protective role, maintaining active capacity of drainage systems.
Use the Flap valve how to correct?
When installing the valve prevents the Court we should insert the valve with vertical axis at an angle of 15° to create the flap valves are always closed in a State when there is no water to escape from inside the storm drain. The installation of the valve lid according to the centerline of the stand is very easy to create a gap in the gate valve, the water and the cute little creatures infiltrate in offsets affect the ability of the sewer drain.
