Whether these controls are energy exchange, pressure reduction or simple container feeding, control elements are required to complete them.

[0003] In the existing regulating valve structure, usually part of the packing assembly structure is arranged inside the valve cover, which results in an increase in the vertical dimension structure of the regulating valve and is not convenient for processing and manufacturing. Secondly, in the existing structure, it is not convenient to install and arrange the actuator part structure, resulting in inconvenient disassembly and assembly. Summary of the Utility Model
