Technical Field

The invention belongs to the technical field of pipeline circulation control, and particularly relates to a valve linearization acquisition device based on a multi-point pipeline and a control system thereof, in particular to the linearization driving control of the circulation volume/circulation pressure in the pipeline.

Background

A pipeline is a device for transporting a gas, liquid or fluid with solid particles, connected by pipes, pipe couplings, valves, etc. Generally, a fluid is pressurized by a blower, a compressor, a pump, a boiler, etc., and then flows from a high pressure portion to a low pressure portion of a pipe, or is transported by the pressure or gravity of the fluid itself. The use of pipelines is very widespread, mainly in water supply, drainage, heating, gas supply, long-distance oil and gas delivery, agricultural irrigation, hydraulic engineering and various industrial installations.

When the gas or liquid in the pipe is initially opened and circulated, the gas pressure or liquid pressure in the pipe changes according to the flow path, the time length, and the size of the valve opening. When information and states of gas and liquid supply of a pipeline are collected in some laboratories or corresponding scenes, the valve is directly and completely opened and is always kept in a fully opened state, pressure in the pipeline can be rapidly increased, impact force of the gas and the liquid in the pipeline can cause impact damage to a testing device connected and communicated with the pipeline, and particularly great loss can be caused to some valuable equipment. If the impact force of the initial circulation stage of gas and liquid in the pipeline can be effectively controlled, the damage of the large impact force to the equipment communicated on the pipeline can be effectively avoided.
