Problems solved by technology

[0003] At present, the size of regulating valve trim is usually designed by the area comparison method. The error will be transmitted to the newly designed product, resulting in cumulative error, and the result obtained is sometimes far from the real result, which affects the regulating performance of the regulating valve

Abstract

The invention provides a design method for the internal size of a regulating valve. According to the method, based on an ANSYS platform and through multiple iterations, the difference value between asimulated flow coefficient and a theoretical flow coefficient is corrected, so that the simulated flow coefficient of the regulating valve is close to the theoretical flow coefficient, the design precision of the internal size of the regulating valve is improved, and the adjusting performance of the regulating valve is improved; and through a specific grid division method and solving arrangement,the simulation calculation error is reduced, each iteration time is shortened, and then the product research and development cycle is shortened.

Description

technical field [0001] The invention relates to the field of automatic instruments and meters, in particular to a method for designing the internal dimensions of a regulating valve. Background technique [0002] In industrial applications, especially in chemical process systems, regulating valves play the role of adjusting medium pressure, flow and other parameters. Its adjustment performance is related to the quality and safety of chemical production, and it is an important control element in chemical process systems. The regulating performance of the regulating valve depends on the error between the Cv value of each opening degree of the valve and the theoretical Cv value; and the Cv value of each opening degree can be realized by designing the flow area of ​​the valve trim at each opening degree. [0003] At present, the size of regulating valve trim is usually designed by using the area comparison method. The error will be transmitted to the newly designed product, resu...
