Description

Plate-type flow adjuster

Technical Field

The utility model relates to a fluid rectification technical field, in particular to board-like flowing adjuster.

Background

The flow conditioner, as a rectifying device, is typically installed upstream of the flow meter conduit, affecting the accuracy of the flow meter measurement. The flowmeter is called as the eye of industrial production, is one of the most important meters in industrial measurement, is widely applied to the industries of petroleum and natural gas, petrochemical industry, water treatment, energy and the like, and has great technological development significance and economic significance.

In the sealed pipeline transportation, flow state distortion is one of the causes of flow metering errors. In practical application, many factors such as valves, elbows, height drop of the pipeline and the like in the pipeline can cause flow state distortion. When the flow regulator is not installed, the best rectification effect can be achieved only by a straight pipe section of 44D-145D (D is the inner diameter of the pipeline, namely the outer diameter of the flow regulator); however, after the flow regulator is installed, the optimal rectification effect can be achieved by reducing the length of the required straight pipe section to 10D-17D.

Typical flow regulators include plate, tube bundle, and vane types.

Although the conventional Akashi/Mitsubishi plate-type flow regulator can achieve a certain rectification effect, the conventional Akashi/Mitsubishi plate-type flow regulator has certain problems in practical application and production and manufacture. It has 35 holes, all the holes have the same diameter, and the hole diameter is 0.130D; the arrangement of the holes is not completely symmetrical, and the holes are specifically distributed as follows: the center of the flow regulator is 1 hole, the second layer is 6 holes from inside to outside, the third layer is 12 holes, and the fourth layer is 16 holes. Due to the characteristic of asymmetric distribution of the holes, the marking of the positions of the holes is complex, so that the holes are difficult to machine and difficult to measure, and the requirements on production technology are high, and finally, the production and manufacturing costs are high.

There is therefore still a need for improvements and optimisation in the design of existing plate flow regulators.
