模锻锤上的滑阀(错气阀)、节流阀与套间隙的大小,在一定程度上影响锻锤的工作效率。配合间隙大了,漏气损失大,气门关不死,打击效率降低;若间隙小了,转动不灵活,容易卡死。滑阀与节流阀和套的配合间隙的大小不仅取决于阀的外形尺寸,还取决于使用的气体,是蒸汽或是压缩空气。下面就分别谈谈滑阀、节流阀与套在使用中的磨损和用压缩空气与蒸汽时的给定间隙,供使用参考。 1.模锻锤上滑阀、节流阀与套在使用中
Forging hammer on the slide valve (wrong valve), throttle and sleeve gap size, to a certain extent, affect the working efficiency of forging hammer. With a large gap, a large loss of air leaks, the valve does not die off, reducing combat efficiency; if the gap is small, the rotation is not flexible, easily stuck. The size of the gap between the slide valve and the throttle valve and sleeve depends not only on the size of the valve, but also on the gas used, which is steam or compressed air. The following talk about the spool valve, throttle valve and sets of wear and tear in the use of compressed air and steam with a given gap for the use of reference. 1.
