气控, 先导式, 平衡滑阀 溢流阀
![RPID : 气控, 先导式, 平衡滑阀 溢流阀](https://cmsimages.sunhydraulics.com/cartg_rpid.gif)
气控先导平衡滑阀结构溢流阀利用压缩空气作用在隔膜上以代替可调节弹簧来控制压力设定。空气信号供给是通过阀的六角螺母部位的导气口进行。此类阀为常闭压力调节阀。当进口(口1) 压力达到阀设定值,阀开始向油箱(口2)溢流,节流以调节压力。此类阀压力调节精度高,压力波动随流量变化小,并且调节平稳,噪声小,响应速度适中。
- 所有2口溢流阀(除了先导溢流阀)在尺寸和功能上可互换(如:给定的外形结构尺寸阀拥有相同的流道,相同的插孔)。
- 可在口2接受最大压力;适合应用在交叉端口的溢流油路中。
- 最大空气压力不能超过150 psi (10 bar)。
- 利用Sun浮动结构减少由于过量安装扭矩或插孔/插装阀加工误差带来的内部零件粘结的可能性。

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.
Direct acting valves are used to prevent over pressure and pilot operated valves are used to regulate pressure. If you are unsure, use a direct acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.

One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.
