Description

Technical Field

[0001] The utility model relates to the technical field of pipeline regulating valve groups, and specifically to a multi-point linkage pipeline regulating valve group. Background Technique

[0002] In modern industrial automatic control systems, pipeline regulating valves, as key devices for controlling parameters such as the flow rate, pressure, and temperature of fluid media, their performance directly affects the operating efficiency and stability of the entire industrial system. With the continuous development of industrial technology, especially in fields such as water treatment, heating, chemical engineering, and petroleum, higher requirements are put forward for the regulation accuracy, response speed, and reliability of pipeline regulating valves.

[0003] At present, common pipeline regulating valves on the market mostly adopt single-valve control or simple multi-valve independent control methods. Single-valve control is difficult to achieve fine flow regulation, especially in situations where large-range regulation and high accuracy are required, and it cannot meet production needs. In addition, in a multi-valve independent control system, each valve needs to independently receive signals and make responses, resulting in a longer regulation response time for the entire system, making it difficult to adapt to rapidly changing production environments. Moreover, multiple independent valves require separate control devices to be installed, increasing the complexity and maintenance difficulty of the system, while also increasing costs.

[0004] At present, in order to achieve the effects of rapid response and cost savings, and at the same time to achieve the effect of convenient control, a corresponding multi-point linkage regulating valve group is usually installed in the pipeline. This type of multi-point linkage regulating valve group realizes the coordinated operation of multiple regulating valves in the pipeline through integrated sensor technology, communication technology, data processing technology, and intelligent control algorithms, in order to achieve precise control of pipeline fluid parameters and improve the overall performance and stability of the system.

[0005] However, when the multi-point linkage regulating valve group is in use, since the adjustment of the valve body mainly relies on the motor drive component for driving, at this time, the motor parts on most regulating valves are directly exposed. At the same time, the valve stem parts of this type of regulating valve are also directly exposed. The exposure of the valve stem part is prone to rust, further affecting the smooth rotation of the valve stem part in the future. The exposure of the motor is also prone to water ingress and damage, affecting its service life, bringing inconvenience to users. In view of this, we have proposed a multi-point linkage pipeline regulating valve group. Content of the Utility Model
