Technical Field

[0001] The utility model relates to the technical field of industrial machine tool bed casting exhaust devices, in particular to a vacuum valve and an industrial machine tool bed casting exhaust device. Background Art

[0002] The exhaust device for casting the industrial mother machine tool body is automatically controlled or remotely controlled by controlling the opening and closing of the valve to connect to the atmosphere and to fill the vacuum container with atmosphere. There is a closed cavity in the vacuum valve with through holes at different positions. Each hole is connected to a different air pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side the magnet coil is energized. Different exhaust holes can be opened or closed by controlling the movement of the valve body, and the air inlet is normally open, so the atmosphere will enter different exhaust pipes.

[0003] However, the current industrial machine bed casting exhaust device carries fine dust during exhaust, which causes blockage of the vacuum valve cavity and affects the normal exhaust opening of the vacuum valve. When exhaust leakage occurs in the vacuum valve exhaust pipe, the industrial machine bed casting exhaust device can only be stopped and the exhaust pipe replaced, resulting in energy consumption costs when the switch of the industrial machine bed casting exhaust device is turned on.
