Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rubber particle former valve, and particularly relates to a rubber particle former valve. BACKGROUND

[0002] The working principle of the rubber particle former valve is to control the movement of the valve core to adjust the flow, pressure and on-off of the molten rubber, so as to ensure that the rubber enters the subsequent forming link (such as pelletizing and extruding) in a stable state, and finally forms rubber particles with consistent specifications. The principle needs to be combined with the characteristics of high viscosity and high temperature of the rubber, and is developed around "fluid control" and "molding coordination".

[0003] The traditional rubber particle former valve uses a single graphite metal mesh packing to compact and seal, and each shift must be checked and replaced. If leakage occurs during work, the machine must be stopped and cooled for maintenance and replacement of parts. When the pipeline is cooled, the material in the pipeline will be caked, and external heating must be assisted when restarting. The time is long, which causes low production efficiency and waste of operation cost. Due to the influence of the packing seal, the working temperature and pressure of the valve cannot be high, the working temperature is below 200°C, the working pressure is below 1MPa, and the stroke height of the valve rod is not easy to control, especially for high precision.
