Advanced methods for assessing sealing ability of valve seals

Abstract


The paper deals with the processes that arise when sealing valve contact surfaces. A mathematical model of elastic contact is proposed that allows solving the problem of deformation of contacting surfaces with allowance for their rigidity by solving a system of linear equations and using the finite element method. To solve the problems of diagnosing and investigating the tightness of contact surfaces, a control and measuring system based on digital speckle interferometry with a continuous laser is proposed.
