Problems solved by technology

Typical flow conditioners include tube bundle type, perforated plate type and vane type. Among them, the structure of the vane type flow conditioner is simple, but the existing Etoile vane type flow conditioner is not obvious enough to rectify the flow field near the inner wall of the pipe, and needs to be further improved

Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0013] like figure 1 and figure 2 Shown is the structure of the vane-type flow conditioner based on Etoile, the inner wall of the regulator pipe is provided with a regular octagonal star-shaped vane group 1, and the distance between the blades in the regular octagonal star-shaped vane group and the center of the flow regulator pipe 0.325D pipe ~0.4D pipe ; where D pipe is the pipe diameter.

[0014] The distance between the blades in the above-mentioned regular octagonal star-shaped blade group and the center of the pipeline of the flow regulator is When , the effect of the flow regulator is optimal.

[0015] The endpoints of the regular octagonal star-shaped blade group are all located on the cross-distributed blades, wherein the cross-dis...

Abstract

The invention discloses a blade type flow adjuster based on Etoile. A regularly-octagonal-star-shaped blade group is arranged in an inner wall area of a pipeline of the adjuster, and the distance between each blade in the regularly-octagonal-star-shaped blade group and the center of the pipeline of the flow adjuster is 0.325-0.4 Dpipe, wherein Dpipe is a pipe diameter. The provided blade type flow adjuster accelerates optimization of the inside flow field of the pipeline, the accuracy and the stability of measurement results of a flowmeter are improved, and development of the flow adjuster is promoted.

Description

technical field [0001] The invention relates to an optimized vane type flow regulator based on Etoile. Background technique [0002] Flowmeter is an important sensing device for energy measurement and industrial process control. The accuracy and stability of its measurement results are directly related to the improvement of the quality of life of the people and the safety and reliability of industrial production scheduling. It is of great significance to energy saving, emission reduction and process control. However, there are generally valves, variable cross-section pipes, elbows and other turbulent devices in the actual pipeline system, which cause different degrees of distortion in the flow field in the pipeline and affect the accuracy and stability of the flowmeter measurement results. Common measures to eliminate the influence of turbulence devices on the flow field in the pipe include the method of extending the straight pipe and the method of flow regulator. Among th...
