活塞式冰箱压缩机凹阀板的优化设计

Design optimization of the valve of piston type refrigerator compressor

针对活塞式冰箱压缩机吸排气阀存在较大阻力并导致制冷效果下降的情况,从压力损失及余隙容积的角度出发,对其凹阀板进行了设计优化,并在样机上进行了试验,试验结果表明该方案是可行的。

In order to lower the pressure loss of valve e xi sting in piston type refrigerator compressor which reduces C.O.P. of the refrige rator,design optimization is made in the valve passage of the suction valve and discharge valve.The experiment shows the amend is viable and profitable.
