Abstract

The invention discloses a novel rapid discharging valve applied to a large foaming machine. Pressure guide oil enters a first oil cavity and a second oil cavity of a pilot valve body through a pilot pressure guide channel, a pilot valve piston moves upwards under the pushing effect of the pressure guide oil till a channel between an oil passing groove and a first valve element hole is completely sealed and blocked, at the moment, a rapid hydraulic oil discharging channel is in a closed state, when the rapid hydraulic oil discharging channel is opened, the pressure guide oil in the first oil cavity and the second oil cavity is discharged through the pilot pressure guide channel, at the moment, the pilot valve piston moves downwards under the action of a first spring, the channel between theoil passing groove and the first valve element hole is rapidly opened, the hydraulic oil, located above a main piston mechanism, in a vertical oil cavity is rapidly discharged through the rapid hydraulic oil discharging channel, and therefore the ascending speed of the main piston mechanism is effectively increased. The novel rapid discharging valve applied to the large foaming machine has the characteristics of being novel in structure, higher in pressure relief speed and higher in practicability.
