Pressurization valve may be malfunctioning. Here is an introduction to the pressurization valve: 1. The pressure reducing valve regulates: reducing the inlet pressure to a required outlet pressure, and relying on the energy of the medium itself to automatically maintain a stable outlet pressure. 2. From a fluid dynamics perspective: the pressure reducing valve is a throttling element with variable local resistance, meaning it changes the throttling area to alter flow velocity and fluid kinetic energy, resulting in different pressure losses to achieve pressure reduction. 3. System regulation: balances the fluctuation of downstream pressure with spring force, maintaining downstream pressure within a certain error range.
