阀片在运动时,不仅有垂直于升程限制器平面的平行运动,而且有倾侧运动,后者对气阀的性能有重要影响[1],但迄今未见到有计算环状阀倾侧运动的文献报导.在本文中,作者提出了一个计算倾侧运动的数学模型,并以一台空压机二级吸气阀为例,作了计算.计算与实测结果相符.通过计算和实测,还发现了在一个阀片上,有可能同时存在阀片颤抖和阀片延迟关闭这两种性质不同的运动,也就是说,当阀片的一部分延迟关闭时,另一部分却发生了颤抖.研究这个现象,将为今后改进气阀性能,提供有益的启示.
When the valve is in motion, there is not only parallel motion perpendicular to the plane of the lift limiter, but also tilting movement, which has an important influence on the performance of the gas valve [1] In this paper, the author proposed a mathematical model for calculating the tilting motion, and took an air compressor two suction valve as an example, made a calculation. Computation and measured results are consistent. Through calculation and measurement, but also It has been found that on one disc, there may be two different types of motions, the trembling of the disc and the delayed closing of the disc at the same time, that is, another part of the disc trembles when a part of the disc is delayed off. , Will provide the beneficial enlightenment for improving the valve performance in the future.
