DEVICE FOR CONTROLLING VACUUM PRESSURE FOR VULCANIZER

摘要

PURPOSE: A device for controlling vacuum pressure for a vulcanizer is provided to lengthen the life of a bladder and to reduce reject rate by keeping the vacuum pressure in the vulcanizer optimal. CONSTITUTION: A pressure detecting line(1) is installed at one side of an inlet line(8). A pressure detecting converter(5) is installed at the pressure detecting line. An air piston valve(2) is connected to a solenoid valve(3). The air piston valve and a filter(4) are installed at the pressure detecting line. A control unit(6) is electrically connected to the pressure detecting converter.
