不可调 直动式溢流阀
不可调的直动式溢流阀为常闭压力限制阀,常用来保护液压元件,以防止其受瞬态压力的冲击。当压力在进口(口1)达到阀的设定值,阀开始向油箱(口2)溢流,节流以限制压力上升。此类阀调节平稳、噪声小,基本为零泄漏,抗油 污能力强,防堵塞并且响应速度快。
- 客户必须指定设定值。阀将在工厂被设定好并防调。
- 各范围的测试压力如下: A 范围 - 2000 psi (138 bar), B 范围 - 1000 psi (69 bar), C 范围 - 4000 psi (276 bar), D 范围 - 800 psi (55 bar), E 范围 - 400 psi (28 bar), S 范围 - 150 psi (10 bar), W 范围 - 3000 psi (207 bar)。
- 回座高于90%测试设定压力。实际设定低于测试设定时,回座百分比可能会降低。
- 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。
- 此阀对变动的油液温度和油液污染不敏感。
- 选择溢流阀的弹簧范围时,为确保最大的可重复性,目标溢流设定值要接近最小和最大压力的中间范围。
- 适合使用在负载锁紧应用中。
- 油箱口(口2)处的背压直接以1:1的比例增加到阀的设定值上。
- 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。

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.
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.
