[0002] The electromagnetic vacuum belt inflation valve is a device used to control the vacuum belt. It can realize the inflation and deflation operation through the electromagnetic control valve to achieve the purpose of controlling the vacuum belt. This device is widely used in various systems that need to control pressure;

[0003] The working principle of the electromagnetic vacuum belt inflation valve can be mainly divided into two parts: inflation and deflation operation; when the electromagnetic valve is opened, compressed air enters the electromagnetic valve from the system, and enters the vacuum belt through the valve control, thereby achieving the purpose of inflation; when the electromagnetic valve is closed, the air inside the vacuum belt enters the electromagnetic valve through the valve, and then is put into the system through electromagnetic control, thereby achieving the purpose of deflation; electromagnetic vacuum belt inflation valve is widely used in systems that need to control pressure, such as vacuum suction cups, suction nozzles, vacuum clamps, etc. It can not only control the pressure of the vacuum belt, but also change its supporting force, so that it can control the workload more accurately.

[0004] The outer surface structure of the valve body of a conventional electromagnetic vacuum belt inflation valve lacks a certain degree of structural protection, which makes it easy for external forces to affect it, resulting in the entire inflation valve having difficulty in maintaining a sufficiently stable operating state. At the same time, the sealing between its structure and the pipeline or connecting structure is also relatively limited.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-stability electromagnetic vacuum belt inflation valve is proposed. Utility Model Content
