Description

Technical Field

[0001] The utility model belongs to the field of flow stabilizing devices, and in particular relates to a plug injection type flow stabilizing device. Background Art

[0002] As an important component in fluid control systems, the core function of flow stabilizers is to ensure that fluids are transported in the system at a stable and controllable flow rate. In many industrial applications, such as chemical processing, pharmaceutical manufacturing, food and beverage production, and energy development, precise flow control is essential to ensure product quality, improve production efficiency, and ensure process safety.

[0003] Traditional flow stabilization devices usually include pumps, valves, flow meters, pressure regulators, and related pipe connections. These devices interact mechanically or electronically to achieve the purpose of controlling fluid flow. For example, a metering pump can provide a constant flow output, and by adjusting the valve opening, the rate at which the fluid passes through the valve can be changed, thereby adjusting the flow rate.

[0004] However, the flow stabilization device of the prior art has a significant disadvantage, that is, the accuracy of flow control is relatively low. This disadvantage is mainly caused by the following factors: First, the reaction time delay: when the flow needs to be adjusted, the regulating valve needs to have a certain reaction time, resulting in a deviation between the actual flow and the set value. Second, pressure fluctuations: under dynamic conditions, such as during startup and shutdown, rapid changes in pressure may lead to inaccurate flow control.

[0005] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content
