Description

Technical Field

[0001] The utility model relates to the technical field of vacuum equipment, in particular to a valve component module adaptable to a vacuum generator system and a vacuum pump system. Background Art

[0002] The valve component module plays a crucial role in the vacuum generator system and the vacuum pump system. In the prior art, due to the significant differences in the working principles of the vacuum generator system and the vacuum pump system, the valve component modules equipped for them must be specially designed and cannot be interchanged. For example, a valve component module designed specifically for the vacuum generator system can only be applied to the vacuum generator system and cannot be used in the vacuum pump system, and vice versa. A valve component module designed specifically for the vacuum pump system can only be applied to the vacuum pump system and cannot be used in the vacuum generator system. The versatility of the valve component module is poor. The vacuum generator system and the vacuum pump system each need to be equipped with their specific valve component modules. Users have to produce and stock multiple different types of valve component modules during production and maintenance to meet the requirements of different systems, increasing the production and maintenance costs. Therefore, it is necessary to improve. Summary of the Utility Model
