Description

Technical Field

[0001] The utility model relates to the technical field of flow detection, in particular to a shock-resistant vortex flowmeter. Background Art

[0002] The primary function of a pipeline flow monitor is to detect and measure the flow rate, pressure, temperature, and composition of fluids in pipelines, thereby helping businesses better control and manage pipeline flow. It can monitor flow in real time and promptly identify and resolve pipeline problems, thereby preventing accidents.

[0003] Vortex flowmeters, developed and manufactured based on the Karman vortex principle, measure the volume flow rate of gases, steam, or liquids, as well as the volume flow rate under standard conditions or mass flow. They are characterized by minimal pressure loss, a wide measuring range, and high accuracy. When measuring operating volume flow, they are virtually unaffected by parameters such as fluid density, pressure, temperature, and viscosity. However, fluid flow in a pipeline or external impacts can generate vibrations, and excessive vibration can reduce flow measurement accuracy. Therefore, we propose a vibration-resistant vortex flowmeter. Utility Model Content

The lower end of the lower shock-absorbing seat is connected to the instrument shock-absorbing assembly by bolts. The upper end of the measuring probe is located between the upper ends of the two instrument shock-absorbing assemblies. By fixing and shock-absorbing the pipeline and the measuring probe, the measurement results are more accurate.

The inner arc surfaces of the shock-absorbing pad 1 are respectively fitted with the outer arc surfaces of the adjacent pipes to absorb the vibration generated when the fluid flows.

[0010] Furthermore, the anti-seismic mechanism also includes reinforcing ribs, and reinforcing ribs are provided on both the left and right sides of the lower end of the lower shock-absorbing seat to improve the mechanical strength of the lower shock-absorbing seat.

[0011] Furthermore, the instrument shock-absorbing assembly includes a shock-absorbing tube and a second shock-absorbing pad.

The fixing seat 1 and the adjacent fixing seat 2 are connected by a support bar through bolts to fix the position of the shock-absorbing cylinder.

[0013] Furthermore, the inner diameter of the measuring cylinder is smaller than the inner diameter of the pipeline, thereby increasing the flow rate.
