| Abstract: | This paper mainly introduced the problem that 120 valve＇s release propagation is too low at small pressure decrement, and proposes an improvement solution for control mode of 120 valve＇s release function, then conducted verification. Furthermore it analyzes increased volume of accelerated release reservoir, and proposes the method of improving release propagation for Type 120 valve after train pipe braking with small pressure decrement. |
