Half-ball type gas energy-saving disk

The utility model relates to a half-ball type gas energy-saving disk, which is suitable for the use of a civil gas stove. The structure of the disk comprises a ventilating hole [1], a half-ball type wind preventing and fire gathering disk [3] with an outer edge and connected with a water support disk [2] in a concave type into integration, reflecting lines [4] of three parallel convex edges arranged on the circumferential inner wall of the half-ball type wind preventing and fire gathering disk [3] and a pan support rack [5] of the three convex edges longitudinally and uniformly arranged along the half-ball type inner wall and connected with the half-ball type wind preventing and fire gathering disk [3] into integration. The disk is arranged on a stove to prevent thermal loss. Gas can be saved by 55% to 60% and time can be saved by 40% to 50%. The gas is sufficiently burnt and the discharge capacity of harmful gas is reduced by 50%.
