Abstract/Summary:
Finite element simulation analysis is the true analytical technique to develop in the last few years and has a extensive applied kind of practical technique on the engineering, which can imitate working process under actual work condition, establish three-dimensional model, compare actual the function of the product after analyzing the data to provide the reference for designer. Valve is indispensable control equipment in kinds of fluidal equipment and has the extensive application in the national economy. Along with the market demand developing, the request of product of valve is also more and more high. Airtight performance is an important index that measures the work function of valve. Seals completely the ratio to press of floating ball valve currently only can get average seals completely the ratio to press of sealing face by adopting the formula calculated, so seals completely the ratio to press of ball valve is analyzed by finite element simulation analysis in the paper, so as to fast and comprehensively comprehend seals completely the ratio to press of ball valve.Regularities of distribution of seals completely the ratio to press begin from the axial, radial and circumferential direction, and compute seals completely the ratio to press when nominal pressure PN is l.OMPa to 1.6MPa and 2.0MPa in the paper, which represent distribute characteristics of seals completely the ratio to press of sealing face, the reason distribute of influencing seals completely the ratio to press ,at last conclusion of the seals completely the ratio to press of sealing face is obtained. A software of finite element analysis that adopt AW software based on establishment and simulation of three-dimensional model ,and attains valid, fast analytical purpose . Abstraction and arrangement of finite element data of node adopt viewable program language-VB, so the language of VB is simple, convenience, easy to operation.
