Description

Technical Field

[0001] The utility model belongs to the technical field of valve islands, and particularly relates to a multi-needle valve island module. Background Art

[0002] The valve island is a control component composed of multiple electrically controlled valves, which are separate components with their own housings. The valves can be attached to separate fastening structures, i.e. separate components, close to each other in a straight line direction. The valves and the commonly used fastening structures form a valve island. The valves can be attached to and removed from the fastening structures. Therefore, the valve island can flexibly use various modules, such as multi-pin control modules and bus control modules, etc. Therefore, according to different working requirements, the valve island needs to replace different control modules to achieve the required working effect.

The disassembly process is relatively troublesome, and therefore needs to be improved urgently. Utility Model Content
