Description

Technical Field

[0001] This invention belongs to the field of pneumatic control, and specifically relates to a pneumatic control system. Background Technology

[0002] In many industrial production processes, the common method for cylinder operation is to connect an air source to a solenoid valve via a hose. After the solenoid valve is activated, the air source is delivered to the cylinder through the hose to drive the cylinder's operation.

[0003] In certain specialized workplaces, such as high-temperature and highly corrosive environments, hoses often experience gas leaks due to aging. This can cause cylinders to fail to operate quickly and promptly, or even stop operating altogether. Inaccurate cylinder operation can easily disrupt the entire production process and even pose safety hazards.

[0004] Replacing hoses promptly is an effective way to solve the above problems, but frequent repairs and replacements cause equipment downtime, affecting operation and incurring significant maintenance costs. Summary of the Invention
