REXROTH OIL CONTROL阀08.45.19-X-Y-Z选型及介绍
Description
When pressure at V2 rises above the spring bias pressure, the check seat is pushed away from the piston and flow is allowed from V2 to C2. When load pressure at C2 rises above the pressure setting, flow is relieved from C2 to V2. With pilot pressure at V1–C1, the pressure setting is reduced in proportion to the stated ratio of the valve, until opening and allowing flow from C2 to V2. The spring chamber is drained to V2. The valve applies a balanced piston and relief is operated at the valve setting independent of back-pressure at V2. However, the piloted opening of the valve remains subject to additive pressure at port V2. For safety and compactness, the C2 port is gasket mounted the actuator.
Note: port identified with M are not protected with calibrated orifice but in direct connection with pressure channels.
描述
当V2处的压力上升到高于弹簧偏置压力时，止回阀座被推离活塞，并允许从V2到C2的流量。 当C2处的负载压力上升到压力设定值以上时，流量从C2释放到V2。 在先导压力为V1-C1的情况下，压力设定值按阀的规定比例成比例减小，直到打开并允许从C2到V2的流量为止。 弹簧腔排空至V2。 阀门使用平衡活塞，并且在阀门设定值下操作安全阀，而与V2的背压无关。 但是，阀的先导打开仍会受到端口V2处附加压力的影响。 为了安全和紧凑，C2端口通过垫圈安装在执行机构上。
注意：标记为M的端口没有经过校准的节流孔保护，而是与压力通道直接连接。
