The invention discloses a quick-opening angle valve with the long service life. The angle valve comprises a pipe body and valve bodies arranged in the pipe body; water inlets and a water outlet are formed in the pipe body, the valve bodies divide the interior of the pipe body into a water inlet cavity and a water outlet cavity, water inlet inner openings and water outlet inner openings are formedin the valve bodies, the water inlet inner openings communicate with the water inlet cavity, and the water outlet inner openings communicate with the water outlet cavity; a valve rod, a handle and a valve element are arranged on each valve body, wherein each valve element comprises a movable block and a fixed block, and a gap is reserved between each movable block and the inner wall of the corresponding valve body; and rolling wheels are rotationally arranged in the valve bodies, rotating shafts of the rolling wheels are parallel to the axes of the valve bodies, the wheel surfaces of the rolling wheels abut against the side walls of the movable blocks, brush rings are arranged on the inner walls of the valve bodies in a sliding mode around the axes of the valve bodies, brushing bristles are arranged at the positions, facing the junctions between the fixed blocks and the movable blocks, of the brush rings, and the brush rings abut against the wheel surfaces of the rolling wheels. According to the quick-opening angle valve with the long service life, good self-cleaning capability is achieved, particulate matter in water can be prevented from wearing the valve elements to a certain degree, so that the service life of the angle valve is prolonged; and moreover, the mechanism movement reliability is high, and disassembling and assembling are convenient.
