Self-adjustable pipeline rectifying device

Abstract

The invention discloses a self-adjustable pipeline rectifying device. A front rectifying body (2) and a rear rectifying body (7) are mounted in a rectifying device barrel (1) in the medium flowing direction from front to back. Front guide plates (3) evenly arranged in the circumferential direction of the front rectifying body (2) are welded to the inner wall of the rectifying device barrel (1) and the outer wall face of the front rectifying body (2), and the front rectifying body (2) is fixed in the rectifying device barrel (1). A guide ring (4) is mounted behind the front guide plates (3). The rear rectifying body (7) is mounted in the downstream direction of the guide ring (4). Rear guide plates (6) evenly arranged in the circumferential direction of the rear rectifying body (7) are welded to the inner wall of the rectifying device barrel (1) and the outer wall face of the rear rectifying body (7), and the rear rectifying body (7) is fixed in the rectifying device barrel (1). A self-adjusting guide cover (5) is mounted on the rear rectifying body (7). A fixed supporting frame (8) is mounted in the rear rectifying body (7). A sliding supporting frame (10) is mounted in the self-adjusting guide cover (5).

Description

technical field [0001] The invention relates to the technical field of valve pipe fittings. Background technique [0002] In the prior art, turbulence occurs due to the increase of the flow velocity of the transmission medium inside the pipeline. As the turbulence intensifies, the pipeline and equipment will vibrate accordingly, and the downstream pipeline network and equipment will also be affected. Severe turbulence inside the pipeline will not only cause a lot of energy loss, but also adversely affect the safe operation of pipelines and equipment. In addition, the severe turbulent flow will also increase the local resistance of the flow, resulting in a blocked flow effect and affecting the transmission volume of the flowing medium in the pipe. The existing method of pipeline rectification mainly adopts adding flat plates parallel to the flow direction inside the pipeline, or deflectors or spiral plates at a certain angle with the flow direction, but simply adding flat pl...

[0002] In the prior art, turbulence occurs due to the increase of the flow velocity of the transmission medium inside the pipeline. As the turbulence intensifies, the pipeline and equipment will vibrate accordingly, and it will also affect the downstream pipeline network and equipment.

Severe turbulent flow inside the pipeline will not only cause a lot of energy loss, but also adversely affect the safe operation of pipelines and equipment

In addition, the severe turbulent flow will also increase the local resistance of the flow, resulting in a blocked flow effect and affecting the transmission volume of the flowing medium in the pipe.

The existing method of pipeline rectification mainly adopts adding flat plates parallel to the flow direction inside the pipeline, or deflectors or spiral plates at a certain angle with the flow direction, but simply adding flat plates parallel to the flow direction, due to the large gap between the plates, It does not play a good role in adjusting the flow performance; the deflector or spiral plate at a certain angle with the flow direction can adjust the flow state in the pipe to a certain extent, so that the fluid spiral flows forward, but it will cause a large flow resistance , leading to more energy loss, and the resulting helical flow will cause more severe turbulence downstream, which cannot improve the flow stability in the downstream pipeline
