Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] Embodiments of the present invention and its implementation process are as follows:

[0024] Step 1: Build a model

[0025] First establish the valve model and the initial noise reduction model, and then extract the fluid domain according to the valve model and the initial noise reduction model to obtain the flow channel model.

[0026] 1.1 Build a pipeline model

[0027] SolidWorks software is used for modeling, valves are placed on the pipeline, and the valve model is obtained by three-dimensional modeling of the valves on the pipeline according to the actual pipeline structure. Such as figure 2 As shown in the figure, it can be seen that the valve model is specifically a three-dimensional model of a butterfly valve.

[0028] 1.2 Establish a noise reduction model

[0029] According to the design requirements, the basic structure of noise reduction is prel...

Abstract

The invention discloses a method for designing and constructing a pipeline valve noise reduction model. The valve model and the initial noise reduction model are established, and the flow channel model is extracted from the fluid domain. The flow channel model is meshed and divided into several sets of flow channel models with different number of meshes. The discharge coefficient and drag coefficient of the flow passage in the flow passage mesh model are calculated, and the results of the discharge coefficient and drag coefficient of the two flow passage mesh models are compared, and only oneflow passage mesh model is obtained. The numerical simulation is carried out, and the flow field is analyzed by the numerical simulation of the flow passage mesh model. The total pressure cloud picture and the velocity cloud picture are intercepted respectively. After analysis, the initial noise reduction model is adjusted to obtain the noise reduction model. The method of the invention can greatly reduce the manpower and material resources and generate smaller waste, and has practical significance in engineering.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a method for designing and constructing an internal structure model of a valve, in particular to a method for designing and constructing a pipeline valve noise reduction model. Background technique [0002] Valve noise is a serious problem often encountered in noise control engineering, especially near large pipeline valves, it will generate relatively large noise, which seriously pollutes the surrounding environment. Since the 1960s, the method of reducing valve noise has attracted widespread attention from all over the world. When studying the causes of noise in the valve conveying liquid and gas, it is found that the control valve of the oil refinery is second only to the compressor and the blower in terms of noise, ranking third. And it has become one of the main hazards in many factories. This kind of noise seriously affects the health of workers and residents near the factory...
