Embodiment 1

[0087] S1: if figure 1 Shown is a two-dimensional drawing of the valve body of the pressure reducing valve to be optimized. According to the design documents of the valve, the three-dimensional structural model of the valve is constructed by three-dimensional modeling software, and the three-dimensional structural model of the pressure reducing valve is as follows: figure 2 shown. Depend on figure 2 It can be seen that the structure of the valve body is symmetrical about the longitudinal section plane of the valve body, so a 1 / 2 valve body model symmetrical about the section plane can be established. In the three-dimensional modeling software, establish the solid model of the pressure reducing valve. According to the internal flow channel of the valve entity model, the internal flow channel model of the valve is extracted. Since the three-dimensional structure model of the valve in this embodiment is 1 / 2 of the valve model relative to the longitudinal section, that is, t...

Abstract

The invention discloses a valve body structure optimization method based on eddy current distribution, which comprises the following steps of: firstly, performing three-dimensional modeling according to a design file of a valve, establishing a complete valve entity model, and establishing a valve internal flow channel model by extracting a flow channel of the valve; calculating a flow field in the valve by utilizing computational fluid mechanics software through mesh generation and a numerical simulation method; through post-processing of a calculation result, visualizing of a valve body flow field to determine eddy current distribution in the valve; through quantitative definition of characteristic parameters of a valve body flow channel and optimization of structural parameters, achieving the effects of eliminating vortexes and improving the flow capacity. The eddy current in the valve can be optimized and eliminated, the flow capacity of the valve is improved, tedious and complex theoretical calculation and experimental correction are avoided, the design process of the valve body is greatly simplified, and a new thought is provided for eliminating the eddy current in the valve and improving the flow capacity of the valve.

Description

technical field [0001] The invention belongs to the field of industrial valve design, and in particular relates to a valve body structure optimization method based on eddy current distribution. Background technique [0002] The valve is a control component in the pipeline fluid delivery system, which is used to change the channel cut-off and medium flow direction, and has the functions of cut-off, diversion, reverse flow prevention, regulation and pressure stabilization. Functions such as diversion or overflow pressure relief. The flow coefficient of the valve is an index to measure the flow capacity of the valve. The larger the flow coefficient value, the smaller the pressure loss when the fluid flows through the valve. Most of the valve manufacturers in industrially developed countries in foreign countries include the flow coefficient values ​​of different pressure levels, different types and different nominal diameters in product samples for selection by design departmen...
