The new differential pressure regulating chamber introduced in this paper is shown in Fig.1. The symbols involved in the paper are described as follows: H_ (i_ (t)) is the head at the time point i, and q_ (i_ (t) F_0 is the area of the impedance orifice; f_4 is the annular area of the outer chamber; H_0 is the head of the steady flow at the confluence; S = φ_3 / φ_2 is the coefficient of cell penetration; φ_2 is the incident wave of the high pressure pipeline ; ψ_2 is the reflected wave in the high-pressure pipeline; φ_3 is the transmitted wave in the pressure tunnel; _1φ is the refracted wave in the riser; φ_4 is the refracted wave in the outer chamber;
