Embodiment 1

[0045] This embodiment provides a valve body optimization design method, the valve body is a DN650 gate valve, including the following steps, the process is as follows figure 1 Shown:

[0046] S1: Establish a three-dimensional geometric model of the valve body;

[0047]The design pressure of the valve is 5.1MPa, the preliminary design of the valve body. The thickness of the preliminarily designed valve cavity wall area 1 is 32.8mm, the thickness of the rib area 2 is 45mm, the thickness of the middle flange area 3 is 95mm, there is a φ60 hole on the rib plate, and the material allowable stress of the valve body It is 138MPa. According to the two-dimensional design drawing of the valve body, the three-dimensional geometric model of the valve body is established by using the parameter method in the three-dimensional geometric modeling software. Due to the symmetry of geometry and loads, it is sufficient to establish a 1 / 2 model.

[0048] S2: Use finite element software to est...

Abstract

The invention provides a valve body optimization design method. A three-dimensional geometrical model is established through a parameter method, thereby facilitating optimization design and greatly shortening design modification time. Through an established stress evaluation rule, various types of stresses which generate different failures are considered. A plurality of evaluation conditions are used for evaluating the stress. Whether the structural strength of the valve body satisfies a safety requirement can be comprehensively and integrally evaluated. Furthermore the economical performance of the structure is evaluated through a stress result. According to an economical performance evaluation standard, contributions of different types of stresses to the structural strength are sufficiently considered, and furthermore a difference between design and reality is considered. When the structure of the valve body satisfies safety evaluation and furthermore satisfies economical performance evaluation, not only is high safety of the valve ensured, but also the material can be saved maximally and the bearing potential of the structure is sufficiently exerted, thereby reducing weight of the valve body, saving material, reducing cost, and making the designed structure more reasonable and more economical.

Description

technical field [0001] The invention relates to a valve body optimization design method, which belongs to the field of valve calculation and optimization design. Background technique [0002] The valve body is one of the most important parts of the valve, and its main function is the flow channel and pressure-bearing parts of the working medium. As the shell of the valve and the main consumable parts, its weight accounts for 70% of the entire valve, and its design level has a decisive impact on the manufacturing cost, working performance and service life of the valve. For a long time, conventional design methods have been adopted for valve body design, usually based on the valve design parameters given by customers, and then using a large number of existing empirical data and empirical formulas to estimate and design the valve body wall thickness. Make appropriate corrections to the product according to the test results of the prototype test. Although this conventional des...
