Beschreibung
Zusammenfassung:	The invention discloses a pneumatic diaphragm valve driving air cylinder with a guide structure, comprising a cylinder body. The cylinder body is sealed through a cylinder cover; a piston is arranged in the cylinder body; a valve rod is fixedly arranged in the center of the piston; the end of the valve rod is slidably connected to the cylinder cover; a first sealing ring is arranged on the contact face of the piston and the cylinder body; and first guide rings are arranged on the two sides of the first sealing ring. The sealing rings and the guide rings are arranged on the contact face of the piston and the cylinder body, so that the sealing performance of the piston and the cylinder body is guaranteed, the piston movement reliability is guaranteed, and the inner wall of the cylinder body is prevented from being jammed and abraded during piston movement; the sealing rings and the guide rings are arranged on the contact face of the cylinder body and the valve rod and the contact face of the cylinder cover and
