气阀是活塞压缩机的重要部件,它的工作直接关系到压缩机运转的经济性和可靠性,而气阀计算繁锁,读图、查表多,速度既慢又非常费事,要想进行多方案选择,费时太多,困难较大。目前国外已广泛采用计算机进行辅助设计工作,如何用计算机,特别是计算机辅助绘图——CAD系统来处理气阀计算乃至绘图,是压缩机行业所关注之事,我们编制了微机辅助环状阀设计应用系统,并取得了一定效果。
Valve is an important part of the piston compressor, its work is directly related to the economy and reliability of the compressor operation, and the calculation of the valve complicated, reading charts, look-up table, the speed is slow and very troublesome, in order to carry out Many options, too much time, more difficult. At present, foreign countries have widely used computer to assist the design work. How to deal with valve calculation and even drawing with computer, especially computer-aided drawing-CAD system is a concern of the compressor industry. We have compiled computer-aided ring valve design Application system, and achieved some results.
