1, Description

The working principle of the ZSPB series of pressure reducing orifices is to decompress the dynamic pressure of the liquid (without static pressure). At present, because of the large number of floors in high-rise buildings, the hydrostatic pressures on the upper and lower floors are different. When the water is discharged, the low-layer water flow pressure is much higher than the high-level water flow pressure. When the fire is extinguished, the low-level fire hose often bursts. This series of pressure-reducing plates have a decompression function for the dynamic pressure of the water flow. When the flowing water passes through the pressure reducing orifice, a pressure drop is generated at the pressure reducing hole due to local resistance loss, thereby satisfying the need for the outlet pressure and flow rate of the fire hydrant.
