Automatic control emergency compensation device for important pipeline

By installing a controller, solenoid valve, and air source accelerator on the standby regulating valve, atmospheric pressure is used to accelerate the connection of the air source, solving the synchronization control problem when the standby regulating valve replaces the main regulating valve. This achieves rapid switching and cost reduction, ensuring the safety and stability of the production workshop.

AI Technical Summary

Technical Problem

In the existing technology, due to the influence of the pipeline length for connecting the backup regulating valve to the gas source and the requirement to meet the working pressure, it takes a certain amount of time for the backup regulating valve to replace the main regulating valve, making it difficult to achieve synchronous and precise control. Furthermore, the use of high-pressure gas sources increases costs.

Method used

An automatic control emergency compensation device for critical pipelines was designed. By installing a controller, solenoid valve, and gas source accelerator on the backup regulating valve, atmospheric pressure is used to accelerate the connection of the gas source and quickly reach the working pressure of the backup regulating valve, reducing the dependence on high-pressure gas sources.

Benefits of technology

It enables rapid switching of backup control valves and rapid attainment of working pressure, ensuring the safe and stable operation of the production workshop and reducing production accidents and labor costs.

Abstract

The utility model discloses an important pipeline automatic control emergency compensation device, and belongs to the technical field of energy supply pipelines. The device comprises a main pipeline and an auxiliary pipeline, wherein two ends of the auxiliary pipeline are respectively connected in parallel with an inlet and an outlet of a main pipeline regulating valve; the auxiliary pipeline is provided with a standby adjusting valve, the standby adjusting valve is provided with a controller in signal connection with the main path adjusting valve, the controller is provided with an instrument panel, and the electromagnetic valve control switch is in signal connection with the controller and used for controlling opening of the electromagnetic valve so as to communicate an outlet of the air source device with an inlet of the air source accelerator. The air source accelerator is provided with an atmosphere acceleration port, and the atmosphere acceleration port is provided with a plugging piece which is communicated with or isolated from external atmospheric pressure. When emergency switching is achieved, the blocking piece opens the atmosphere accelerating opening after the electromagnetic valve is opened for inflation, so that connection of an air source is accelerated through atmospheric pressure, the working pressure of the standby adjusting valve is rapidly achieved, an air source with higher pressure does not need to be used, and cost is reduced.
