Flow adjusting valve

Abstract

The invention discloses a flow adjusting valve. The flow adjusting valve comprises a valve body, wherein a medium entrance channel, a communicating cavity and a medium flow-out channel are arranged onthe valve body; and the medium entrance channel is provided with the inner end which communicates with the communicating cavity and the outer end which communicates with the outside. The flow adjusting valve also comprises a flow adjusting mechanism, wherein the flow adjusting mechanism comprises a rotary body; the rotary body is in rotation fit with the communicating cavity; the rotary body comprises an operating end which extends to the outside of the valve body so as to drive the rotary body to be rotated and a plurality of flow channels which are positioned in the communicating cavity andhave different diameters; each of the flow channels is provided with an inlet end and an outlet end; each of the inlet ends is positioned on the peripheral surface of the rotary body and distributedon the same circumference, corresponding to the inner end position, of the peripheral surface; each of the outlet ends communicates with the medium flow-out channel; and when an operation part is rotated to an on-state position, any one of the inlet ends of the rotary body communicates with the medium entrance channel. The flow adjusting valve disclosed by the invention has the advantage that through cooperation between the operation part and the flow channels with different diameters, the aim of adjusting the volume of the flow is fulfilled.

Description

technical field [0001] The invention relates to the field of valves, in particular to a flow regulating valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. It is a device that makes or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow relief. [0003] The existing flow regulating valve includes a valve body, a valve cavity is arranged ...

AI Technical Summary

Problems solved by technology

[0003] The existing flow regulating valve includes a valve body, a valve cavity is provided in the valve body, a medium inflow channel and a medium outflow channel connected with the valve cavity are provided on the valve body, a valve core is provided in the valve cavity, and a valve core is provided on the valve core. There is a valve stem, and the conduction and cut-off of the valve can be realized by controlling the rise and fall of the valve core during use. However, the flow control valve with this structure is time-consuming and laborious to control the lift of the valve core, which is inconvenient to operate and high in manufacturing and maintenance costs. Easy to use, and although the medium flow can be controlled, the medium flow cannot be precisely adjusted

When it is necessary to precisely adjust the medium flow, the existing valves cannot meet this requirement
