Description
Technical field
The present invention relates to a kind of regulating valve, specifically a kind of labyrinth type antiscour regulating valve.
Background technology
Regulating valve also known as control valve, in industrial automation process control field, are exported by receiving regulation unit
Control signal, by power operation go change media flow area, reach to technological parameters such as flow, pressure, liquid levels most
Whole control device.Typically it is made up of executing agency and valve.If by stroke feature, regulating valve can be divided into Direct Travel and angle stroke
；Match somebody with somebody the power that executing agency uses by it, be divided into linear characteristic by its function and characteristic, equal percentage characteristics and parabola are special
Three kinds of property.Regulating valve is applied to the media such as empty gas and water, steam, various Korrosionsmediums, mud, oil product.English name：
Control valve, regulating valve common classification：Pneumatic control valve, electric control valve, hydraulic adjusting valve, direct-operated regulator.
And for the restricting element in regulating valve, traditional structure is telescoping structure or is disk type structure, use
Such structure is when being throttled, and the pressure of medium is big, and corresponding flow velocity is very fast, therefore regulating effect is not when adjusting flow
It is good.
Therefore for above-mentioned phenomenon, a kind of new antiscour regulating valve is refer in patent CN105605305A, including
