Problems solved by technology

[0002] Accurate control of gas or liquid flow has always been a difficult problem. The current market for gas flow control equipment (commonly known as flow valves) has the disadvantages of low precision, large errors, and short life, which cannot meet the needs of production and life in the era of real science and technology.
[0003] Most of the existing flow valves control the flow by adjusting the distance between the piston and the air nozzle, and the piston is often threaded with the valve body, but the threaded connection itself has an assembly gap, so there is low control accuracy; due to some high-tech industries The gas flow requirements are very high, and the current electronic flow control valves on the market are generally relatively expensive, and the control accuracy is low; custom-made electronic flow control valves that meet the precision requirements are more expensive and cannot meet the actual production needs of high-end industries. Therefore, many technical solutions cannot be implemented in actual production.

Abstract

The invention relates a flow control valve. A first through hole in the adjusting ring is gradually away from a first flow hole through an adjusting rod in a rotating valve body, the side surface of the adjusting ring gradually seals the first flow hole in the process, and the flow of the gas or liquid is controlled; due to the fact that the first through hole directly communicates the first flowhole with a second flow hole, gas or liquid is input from the first flow hole through the first through hole and is output from the second flow hole; or the first through hole is indirectly communicated with the second flow hole through the valve hole, the first through hole is communicated with the second flow hole through a valve hole part between the adjusting ring and the second flow hole, gasor liquid sequentially passes through the first through hole and the valve hole from the first flow hole and is output from the second flow hole; or due to the fact that the first through hole is opposite to the first flow hole, the first through hole is communicated with the second flow hole through the second through hole in the adjusting rod, and gas or liquid enters the first through hole from the first through hole in sequence from the first flow hole, the second through hole is output from the second flow hole. The precision is high, the cost is low, and the applicability is wide.
