美國MAC氣動換向閥,MAC氣動換向閥安裝方式
 The 4-way pilot develops maximum shiftingorce both ways.
2. Memory spring available.
3. Balanced spool, immune to variations ofpressure, also provides high flow.
4. Short stroke with high flow.
5. Bonded spool with minimum friction, shiftingin a glass-like finished bore.
6. Pilot with balanced poppet, high flow, shortand consistent response times.
7. Wiping effect eliminates sticking.
換向閥主要由閥體、密封組件、凸輪、閥桿、手柄和閥蓋等零部件組成(圖1)。
閥門由手柄驅(qū)動，通過手柄帶動閥桿與凸輪旋轉(zhuǎn)，
凸輪具有定位驅(qū)動與鎖定密封組件的開啟與關(guān)閉功能。
閥瓣為碳鋼板焊件，設(shè)有加強筋，即增加閥瓣強度又起導(dǎo)向作用，保證每組閥瓣間的同軸度。

閥瓣上鑲嵌聚氨脂橡膠圈，該材料具有耐油、耐磨損、穩(wěn)定、密封良好和使用壽命長的特點。
在凸輪的作用下，密封圈的球面與閥體密封面相接觸產(chǎn)生擠壓彈性變形，達(dá)到密封效果。
