When the water pressure in the plastic hose is changed greatly, the elasticity of the compensation film 5 cannot resist the water flow from the water injection port 4-4, and the high-pressure water flow can force the compensation film 5 to deform greatly and sink into the pressure stabilizing cavity, so that the deformed compensation film 5 blocks the passage leading from the water inlet 2-5 to the pressure stabilizing cavity, the water flow flowing from the high-pressure cavity to the water inlet 2-5 is completely led to the turbulent flow passage 3-5, the flow passing area in the pressure stabilizing cavity is reduced, and the water outlet flow rate of the water outlet 2-7 is controlled; on the contrary, when the pressure in the plastic hose becomes lower, the deformation of the compensation film 5 becomes smaller, and the flow area in the pressure stabilizing cavity becomes larger; therefore, the flow stability under different pressures can be kept, and the compensation effect is achieved.
