Embodiment 1

[0050] S1: According to the design documents of the valve, the valve entity model of the valve to be optimized is constructed by 3D modeling software. The valve to be optimized used in this embodiment is a black water angle valve for coal chemical industry. Such as figure 1 As shown in (a), the black water angle valve is composed of valve seat 1, lower bushing 2, upper bushing 3, valve body 4, valve cover 5 and integral valve core 6. Since the structure of the valve body is symmetrical about the longitudinal section plane of the valve body, a 1 / 2 valve body model symmetrical about the section plane can be established, and the established valve entity model is as follows figure 1 (b) shown.

[0051] S2: According to the obtained valve entity model, extract the internal flow channel model of the valve, the steps are as follows: Create a solid geometry in the 3D modeling software Solidworks as the matrix, so that the matrix contains the currently constructed black water angle v...

Abstract

The invention discloses a valve body wall thickness lightweight design method based on erosive wear, which comprises the following steps of: firstly, performing three-dimensional modeling according to a design file of a valve, establishing a complete valve solid model, and extracting a flow channel of the valve to establish a valve internal flow channel model; carrying out flow field calculation in the valve by utilizing computational fluid mechanics software through grid division and a numerical simulation method; through post-processing of a calculation result, achieving visualization of a flow field of the valve body, and determining a wear area and a non-wear area in the valve; and through quantitative definition of parameters of a non-wear area of the valve body, setting experimental points, and performing structural optimization on the valve body. According to the method, the redundant wall thickness of the valve body can be preferably removed, the mass of the valve body is reduced, 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 lightweight design of the valve body.

Description

technical field [0001] The invention belongs to the field of industrial valve design, and in particular relates to a lightweight design method for valve body wall thickness based on erosion and wear. Background technique [0002] As a key component in industrial piping systems, valves regulate and control parameters such as flow, pressure, and temperature. They are widely used in aerospace, military, nuclear energy, and electric power. They are called the "throat" of industrial systems. my country's mid-to-high-end valve-related technical level is at a critical stage of advancing from low to high. Lightweight, intelligent, and integrated will be the mainstream direction of the development of control valves. The lightweight development of valves will save a lot of materials for our country, effectively reduce the economic cost of valves, and expand the application fields of valves, which is of great significance to promote the development of my country's valve industry. Than...
