A check valve (4) can swing around a shaft (11) which is in certain distance from the check valve (4). Additionally, the check valve (4) is connected with a supporting arm (9) bent into 90 DEG arc shape. A connecting block (10) that can rotate around the shaft (11) is arranged on the supporting arm (9). A screw (13) is arranged on the supporting part (12) at the upper end of the arc supporting arm (9) and is perpendicular to the plane of the check valve (4) while supporting balanced weights (14 and 16). Wherein, the balanced weight (14) can move in vertical direction along a bolt (13) and can be fixed at a certain position. When the balanced weight (14) is moving, the total center of gravity of all moving mass is moving in one line. This line passes through the shaft (11) and is perpendicular to the plane of the check valve (4). |
