Abstract

Tensile and compression tests on pure PTFE, 10% carbon fiber PTFE and 20% carbon fiber PTFE were carried out on the universal material testing machine at three temperatures of 20°C, 60°C and 90°C, accepted the tensile elongation and tensile strength of this material at different temperatures. Finite element analysis is performed on pan plug seals made of three materials at different temperatures and 105 MPa. The simulation results show that when the maximum Mises stress of the outer lip of the three materials increases to a certain amount, an inflection point will appear, and the maximum Mises stress increase before the inflection point is large after the inflection point, the Mises stress increment gradually decreases. The higher the carbon fiber content, the greater the maximum Mises stress value of the lip; as the temperature increases, the seals of the three materials are less prone to tensile failure; the material with less carbon fiber content, the less stretched. When the valve stem moves up and down, the stress value of the inner lip changes more than the stress value of the outer lip; the upward stroke is conducive to the realization of the seal; the part near the end of the inner lip is more affected by the movement of the valve stem. This article provides a certain basis for the selection of pan plug seals.
