The invention belongs to the technical field of pressure adjusting fine control and particularly relates to a high-pressure fine movement regulating valve based on an air spring. An air spring cavityand an air spring cavity welding base are connected through argon arc welding. The upper portion of the air spring cavity is provided with a locking cover. The lower end face of the air spring is connected with an air spring connection base through a first internal hexagonal bolt, and the whole is put into the air spring cavity. A reset spring is arranged between the air spring connection base andthe air spring cavity welding base. The upper end of a valve fixing base is connected with the air spring cavity welding base through a second internal hexagonal bolt. A regulating valve body is arranged at the lower end of a valve fixing base. The regulating valve body is connected with the air spring connection base through a valve coupler and a limitation connecting shaft. The high-pressure fine movement regulating valve based on the air spring can be widely applied to the technical field of hydraulic pressure. Especially in aerospace and other industries with special requirements, different process requirements can be met, multiple hydraulic regulating manners are achieved, the structure is concise and compact, the cost is low, and maintaining is easy.
