Abstract
The utility model discloses a labor-saving type changeover valve which comprises a valve body and a valve element. The valve body is provided with a water inlet, a first water outlet, a second water outlet, a first water passing hole communicated with the first water outlet, and a second water passing hole communicated with the second water outlet. The valve element is connected to the valve body in a sliding mode, and the labor-saving type changeover valve further comprises an upper sealing piece, a middle sealing piece and a lower sealing piece. The upper sealing piece, the middle sealing piece and the lower sealing piece are vertically and sequentially arranged on the periphery of the valve element in a spaced mode. The upper sealing piece and the lower sealing piece both are in slide fit with the valve body in a sealing mode. The middle sealing piece slides between a first sealing position and a second sealing position, wherein the first sealing position seals the first water passing hole so as to enable the water inlet to be communicated with the second water outlet, and the second sealing position seals the second water passing hole so as to enable the water inlet to be communicated with the first water outlet. The horizontal size of the middle sealing piece is larger than that of the upper sealing piece or the lower sealing piece. Changeover force needed in the pulling or down-pressing process of the labor-saving type changeover valve is greatly reduced, and more labor is saved.
