进排气阀的温度分布是其设计计算的重要准则。按发动机达到的温度程度,须准确地选择阀的材料与尺寸。 Teves-Thompo公司(Barsingnausen)提出了两种测定阀温度分布的方法。A方法是,通过一个特别的测温阀,按其硬度的下降,测出其温度变化。B方法是,在给定的边界条件下,测定长时间试验运转后阀的温度变化。 Intake and exhaust valve temperature distribution is an important criterion for its design and calculation. Press the engine to achieve the degree of temperature, the valve must be accurately select the material and size. Teves-Thompo Company (Barsingnausen) proposed two methods to determine the valve temperature distribution. A method is through a special temperature valve, according to the decline in its hardness, measured temperature changes. Method B is to determine the change in temperature of the valve after a long period of test run at a given boundary condition.
