The radial constrictions 3-2 of the core sleeve 3 are four circumferentially and evenly distributed, and radially outward convex ribs 3-3 are arranged between the radial constrictions 3-2. The overflowing core body 5 is provided with an inner core 5-2 with a cross section in a shape of Chinese character 'mi', the inner core is provided with eight side wings extending radially outwards, wherein four side wings which are symmetrical radially are connected with the inner wall of the overflowing core body 5, and the water inlet channel A5-1 is formed between the four side wings connected with the inner wall of the overflowing core body 5.

The flow stabilizer can be divided into two parts according to a flow passage, wherein the first part consists of a retainer ring seat 1 and a plastic retainer ring 2, and the second part consists of a core sleeve 3, a rubber ring 4 and an overflowing core body 5. When in use, the first part of through flow is throttled into first water flow, the second part of through flow is throttled into second water flow, and the two water flows are collected and output in the mounting pipe.
