Permanent magnetic pole pneumatic reversing device

Abstract

The invention discloses a pneumatic reversing device for a permanent magnet pole. The pneumatic reversing device comprises a cylinder barrel; one end of the cylinder barrel is provided with a reversing valve; two ends of the cylinder barrel are provided with an upper end cover and a lower end cover; the cylinder barrel is internally provided with a sliding plug, a sliding plug rod, a pull rod and a reciprocating sleeve; the reversing valve is arranged above the upper end cover; a valve body of the reversing valve is internally provided with a first air passage and a second air passage; one end of a valve element of the reversing valve is sleeved by a spacer bush, an inner magnet ring and a valve element nut; one end of the reciprocating sleeve is fixedly provided with an outer magnet ring having the same axis with the inner magnet ring; the sliding plug, the upper end cover and the inner wall of the cylinder barrel form an upper air cavity; the sliding plug, the lower end cover and the inner wall of the cylinder barrel form a lower air cavity; the first air passage communicates with the lower air cavity; and the second air passage communicates with the upper air cavity. The pneumatic reversing device is capable of simplifying a reversing structure, increasing the reversing efficiency and improving the stability, small in reversing mechanism size, low in noise, stable in performance, simple in manufacture, simple and beautiful in appearance, free of mechanical collision or spark discharge phenomenon and very suitable for occasions with anti-explosion requirements.

Description

technical field [0001] The invention relates to the technical field of reversing of automatic reciprocating equipment, in particular to a permanent magnet magnetic pole pneumatic reversing device.
