Description

Technical Field

[0001] The utility model relates to the technical field of flow stabilization equipment, in particular to a novel flow stabilizer. Background Art

[0002] With the development of science and technology, liquid boosting equipment is becoming more and more common. However, the pressure fluctuation range of liquid boosted by boosting equipment is relatively large, and the flow rate is not stable. Unstable liquid flow will bring unexpected effects or even damage to the pipeline and the entire system. For example, unstable liquid flow will produce noise and cause pipeline vibration. The large pressure fluctuation range will also lead to inaccuracy of the equipment's built-in pressure detection.

[0003] At present, the device for stabilizing liquid pressure and flow mainly relies on the spring element inside the device to fix a valve core, and the valve core and the through hole in the device form a liquid passage. The size of the through hole is adjusted by the up and down movement of the valve core under the impact of water flow of different pressures, thereby playing a role in stabilizing pressure and flow. From the perspective of fluid mechanics, the liquid pressure and flow stabilizer is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure stabilization, and relying on the adjustment of the control and regulation system, the fluctuation of the outlet pressure is balanced with the spring force, so that the outlet pressure remains constant within a certain error range.

[0004] The current devices for stabilizing liquid pressure and flow have low adjustment accuracy, large outlet pressure fluctuations, large valve core vibrations, large noise during operation, and unstable flow. Utility Model Content
