Description

Technical Field

[0001] This utility model relates to the technical field of distributors, specifically a pneumatic distributor valve body. Background Technology

[0002] A pneumatic distributor is a device used to distribute, control, or switch the direction of compressed air flow. It is widely used in industrial automation systems. The working principle of a pneumatic distributor is usually as follows: it switches the position of the valve core, changes the flow path of compressed air, or controls the action of cylinders or other pneumatic actuators by means of electromagnetic or mechanical means, thereby completing the corresponding work.

[0003] In existing technology, Type I and Type II pneumatic distributors are used in hydraulic press pump station systems. They are mainly used to control minimum liquid level valves, hydraulic gate valves, pump circulation valves, and as bypass valves. This is particularly relevant for large hydraulic press pump stations and control systems.

[0004] Because the main pump and hydraulic control system contain numerous control valves, a large number of pneumatic distributors are also required. Since the valve cores and other auxiliary components of these pneumatic distributors are identical, and the valve bodies are not interchangeable, this increases the difficulty of equipment use and maintenance.
