Abstract

The invention discloses a method for measuring working temperature of a valve, belonging to a method of temperature measurement, in particular to a method for measuring temperature of material samples by combining a sampling device. According to the principle that after tempering is carried out on material after hardening, different tempering temperatures correspond to different hardness, in the invention, after hardening is simultaneously carried out on a small barstock sample and the measured valve, temperings of different temperatures are carried out to measure the hardness, a standard tempering temperature-hardness corresponding curve of the barstock is charted, and temperature conditions of various parts of the valve are obtained by measuring the hardness of various parts of the valve and comparing the measured hardness with the standard tempering temperature-degree of hardness corresponding curve. The invention well solves the problem that the working temperature of the valve can not be measured and provides a new method for the research and development of new valve products.

Description

technical field

[0001] The invention belongs to a method for measuring temperature, in particular a method for measuring the temperature of a material sample combined with a sampling device. Background technique

[0002] The valve is a part of the engine's valve mechanism, which ensures that the engine is opened and closed on time during operation, and fresh combustible mixture is input into the cylinder, and the exhaust gas after combustion is discharged from the cylinder in time. Measuring the exact valve operating temperature can provide data for valve design. Because the valve is in a dynamic state, it is reported to use a thermocouple to measure, but the thermocouple measurement device is very complicated, the measurement cost is expensive, and only one point of temperature can be measured, and the distribution of the valve temperature field cannot be measured. Contents of the invention

[0003] The object of the present invention is to provide a method for indirect ...
