通过对往复式压缩机网状阀内气体流动特点的分析，把气流通过网状阀时的流动损失分为四个部分：阀座流动损失、气流通过气阀第一次和第二次转弯时流动损失及出。流动损失。通过对气阀的吹风试验，分别得到了各个部分流动损失系数与升程、阎庄通道宽度比Ｈ／ｂ的关系式，进而得到气阀的有效通流面积与Ｈ／ｂ的关系式，与现有的公式相比较，取得了满意的结果。
Through analyzing the characteristics of the gas flow in the reciprocating compressor mesh valve, the flow loss of the gas flow through the mesh valve is divided into four parts: the flow loss of the valve seat, the flow of air through the first and second turn of the valve Loss of flow and out. Loss of circulation. Through the air blowing test on the valve, the relationship between the flow loss coefficient and the lift and the width ratio H / b of Yanzhuang channel were obtained respectively, and then the relationship between the effective flow area of the valve and H / b was obtained, and Compared with the existing formula, the satisfactory result has been obtained.
