配气阀是铆钉机的“心脏”,它使压缩空气按预定的规律交替地进入气缸的前腔或后腔,实现锤体的连续往复运动。目前国内外各种规格的气动铆钉机多数采用具有三个台阶(中间台阶直径较大)的筒状配气阀配气。虽然这些阀的尺寸、形状、台阶上有无沟槽,以及沟槽的位置各不相同,但是阀换向的控制方式是相同的。在 The valve is the “heart” of the riveter. It allows the compressed air to alternately enter the front chamber or the rear chamber of the cylinder in accordance with a predetermined rule to achieve a continuous reciprocating movement of the hammer body. At present, most of the pneumatic riveters of various specifications at home and abroad use a cylindrical valve with three steps (larger middle step). Although the size, shape, and the presence or absence of grooves in the steps and the positions of the grooves are different among these valves, the valve commutation control method is the same. in
