A method for calculating the wall thickness of an industrial steel valve body

Abstract

The invention discloses a design and calculation method for the wall thickness of a steel valve body of an industrial valve, which belongs to the field of industrial valve design. The present invention overcomes the deficiencies in the prior art, and provides a new design and calculation method to calculate the wall thickness of the valve body, which includes the following steps: first calculate the wall thickness of the base valve body and the branch roads outside the bifurcation area, and then calculate the The wall thickness of the fork area; according to the shape characteristics and forming methods of the basic valve body and branch, different calculation methods are used to obtain the initial wall thickness; the wall thickness of the bifurcation area is calculated and checked by force balance, based on The pressure load area and the compensated effective metal cross-sectional area size determine the wall thickness in the bifurcation region. The invention comprehensively considers the shape and forming method of the valve body, thereby making the design of the valve more reasonable, reducing the wall thickness of the valve body, reducing the weight of the valve body, improving the existing design method of the valve body, and promoting the lightweight development of the valve , which has scientific guiding significance for guiding valve design calculations.

Description

technical field [0001] This application relates to the field of industrial valve design, in particular to a design calculation method for the wall thickness of a steel valve body. Background technique [0002] With the rapid development of my country's economy and the improvement of industrial automation, my country's equipment manufacturing industry is in urgent need of transformation and upgrading. The national "13th Five-Year Plan" clearly points out that it is necessary to implement industrial strong foundation projects. Valves are used as core components to support intelligent manufacturing. The basic components of the project, the quality of the valve is directly related to whether the industrial automation device can operate safely and reliably. [0003] The design and calculation of the valve body wall thickness is the basis of valve design. The current valve body design theory is based on the design theory of internal pressure vessels, ignoring the shape and forming ...

Problems solved by technology

[0003] The design and calculation of the valve body wall thickness is the basis of valve design. The current valve body design theory is based on the design theory of internal pressure vessels, ignoring the shape and forming method of the valve body, which cannot accurately fit the actual working conditions of the valve and reflect the common characteristics of the valve body. The stress in the working state leads to many unreasonable calculations of the valve body wall thickness, which limits the further development of the valve industry
