The utility model relates to a pressure reducing valve and a pressing fire extinguishing device. A pressure reducing valve is arranged between the power gas container valve and the extinguishing agent container, which can be opened slowly and automatically adjust pressure and reduce pressure. One end of the main spring of the pressure reducing valve is provided with a piston, and the other end of the piston is provided with a buffer cavity. When the piston reaches the setting pressure adjustment ring, the valve core performs normal pressure reduction under the influence of the main spring. The utility model can adjust and reduce the pressure of constant output of energy, can effectively in time and make full use of the dynamic energy of gas, increase the transmission distance of fire extinguishing agent, improve the atomization performance, improve the efficiency of fire, and slowly open the valve, effectively avoid the high power gas rapid release of fire extinguishing agent the container consists of overpressure.
