To close the fluid guideway.

In addition, a crossbar is provided on the top of the guide beams in a direction orthogonal to the guide beam, and the upper side of the balance gate rotated to the crossbar is locked.

The balance gate may be made of recycled synthetic resin material.

In addition, both ends of the balance pin of the balance gate are rotatably fitted into the inner circumferential hole of the fixing member which is fitted into the pinhole formed on the wall of the edge frame from the outside to the inside.

In addition, it is preferable to form a plurality of fluid guide grooves to guide the downward movement of the fluid on the inclined surface of the balance gate.

In addition, it is possible to fix the fluid guide plate having a downward inclination angle for guiding the fluid to the fluid guide path on the top of the guide beam so that the clockwise rotation of the balance gate is controlled by the lower end of the fluid guide plate.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the grating having a flow path opening and closing balance gate according to the present invention will be described in detail, the related art, etc. in describing the present invention may obscure the gist of the present invention If it is determined that detailed description will be omitted.
