The invention relates to a flow rate regulator, and in particular relates to a bend pipe flow rate regulator which comprises a bend pipe with a flange. The regulator provided by the invention is characterized in that the bend pipe is formed by sequentially assembling a series of flow rate regulating bend pipes with different diameters and different bend curvatures; and the ratio of the diameter of each flow rate regulating bend pipe to the curvature semi-diameter corresponding to the position of the flow rate regulating bend pipe is equal or approximate. The bend pipe flow rate regulator provided by the invention has the advantages that the structure is unique, centrifuge impact force is eliminated maximally, the flow rate of a fluid flows out of the bend pipe is distributed uniformly, the vibration of a regulating valve set is eliminated, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to a flow velocity regulator, in particular to an elbow flow velocity regulator. Background technique [0002] A flow conditioner is a device that eliminates abnormal flow and shortens the length of necessary straight pipe runs. There are many kinds of flow regulators currently available on the market, but all of them are designed and manufactured for partial rectification of straight pipes. Elbow is one of the blocking parts in the process pipeline. When the fluid flows through the elbow, it will produce "distortion of velocity distribution", "swirling flow" and "unsteady flow". In the pipe of the elbow, due to the turning of the fluid, there is a centrifugal force from the center of curvature to the outer wall of the pipe, which makes the pressure on the outer wall increase and the pressure on the inner wall decrease when the fluid transitions from the straight section of the pipe to the elbow section. Therefore, the flow velo...
