<p>The present invention relates to an air flow check valve and a system incorporating a plurality thereof, having a function for rectifying the flow of air produced by compression and expansion of air in a closed air vessel which in turn is caused by the force of waves of the sea, as well as a function for regulating the pressure of rectified air flow, the air flow check valve having an air chamber, a liquid stored in the air chamber, a pipe extending into the air chamber and immersed in the liquid a predetermined depth, an inlet connected to the pipe and an outlet opening into the air chamber, wherein, when the air pressure at inlet becomes higher than the pressure at outlet by an amount corresponding to the depth of immersion of the pipe in the liquid, the air is discharged through the outlet and when the air pressure at the outlet higher than that at the inlet, the air forces the liquid in the air chamber into the pipe until the level of the liquid in the pipe rises at the immersion depth, so that the air flow-back from the outlet to the inlet is checked until the level of liquid in the air chamber falls down to the lower end portion of the inlet pipe, because the cross-sectional area of the pipe is much smaller than that of the air chamber, and therefore being applied for a system for checking air flow and incorporated with an energy converting plant for converting wave energy into electric energy.</p> |
