Novel flow control valve

Abstract

The invention discloses a novel flow control valve, and relates to the field of flow control over pipelines. The novel flow control valve comprises a pipeline, a sealing pipe is installed on the outerside of the pipeline, a plurality of flow adjusting plates inserted into the pipeline are arranged in the sealing pipe, and a servo motor and a gear ring are arranged on the inner wall of the sealingpipe; and a gear is fixed to the driving end of the servo motor and engaged with the gear ring, the gear ring is connected with the inner wall of the sealing pipe in a sliding mode through a sealinggasket, an oblique gear ring is fixed to the side, away from the servo motor, of the gear ring, and a plurality of threaded rods are rotatably mounted on the side, close to the oblique gear ring, of the inner wall of the sealing pipe. Bevel gears are installed at the top ends of the threaded rods and engaged with the bevel gear ring, and the bottom ends of the threaded rods and the flow adjustingplates are installed in a threaded mode. According to the flow control valve, the flow of fluid in the pipeline can be rapidly, conveniently and stably adjusted through the arrangement of all the structures, the adjusting range of the flow control valve is 0-100%, and influences on the original flow of the pipeline can be avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline flow control, in particular to a novel flow control valve. Background technique [0002] With the development of industrial technology, the application of pipeline fluid switching is gradually increasing. The valve is an important equipment for pipeline flow control, and the fast response performance has become an important design index of the valve, especially in aviation, nuclear power and other fields. , it is necessary to realize rapid circulation or blocking control of the fluid in the pipeline. [0003] After retrieval, Chinese Patent No. CN 206310049 discloses a flow control valve device. There is a sealing gasket on the annular valve baffle; the main shaft of the valve fixed in the fluid channel has a flexible skin of the valve at one end, and several skin skeletons are installed circumferentially on the inner side of the flexible skin of the valve; the shaft of the main shaft of the val...

AI Technical Summary

Problems solved by technology

[0004] The flow control valve in the prior art has the following disadvantages: when adjusting the flow of the pipeline, the various structural components inside the pipeline will occupy the internal space of the pipeline, resulting in blocking the fluid and reducing the original fluid throughput of the pipeline. It occupies and wastes the function of the pipeline. At the same time, when the flow is adjusted, the flexible skin of the internal valve moves unstable, and the damage to the structure itself is relatively large. Therefore, we propose a new type of flow control valve
