Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic components, and particularly relates to a base structure applicable to valve island type pneumatic components and having expandable functions. Background Art

[0002] The valve island is an important part of industrial production, and it is a key equipment set responsible for regulating and controlling fluid flow in the control system. In the prior art, valve island type pneumatic components (such as valve island type solenoid valves, valve island type vacuum devices, etc.) all adopt a manifold as the base, and use the manifold to install and fix each valve unit or vacuum unit in the valve island type pneumatic components. For example, a valve island with a same-side layout of multifunctional valve position coils disclosed in a Chinese patent application (publication number: CN114110227A) includes a control unit, a manifold, and multiple single valves. The control unit and the multiple single valves are all installed on the manifold, the multiple single valves are arranged side by side on the manifold, each single valve includes a pilot valve and a main valve body, the pilot valve is used to control the main valve body, each pilot valve includes a valve seat and a valve position coil assembly arranged up and down, and each valve position coil assembly is located on the same side of the manifold. However, the defect of the manifold in this structure is that once it is produced and processed, its size, installation hole positions, etc. are fixed and cannot be changed, so that it cannot be expanded, and the number of single valves that can be installed on the manifold is also limited as a result, which is not flexible enough. When the user needs to additionally increase the number of single valves, the original manifold can no longer meet the requirements, and it may be necessary to redesign the manifold, which is time-consuming and laborious. Therefore, it is necessary to improve it. Summary of the Utility Model
