功能说明 Function description

DR10DP型阀是三通结构直动式减压阀、即在减压侧具有溢流功能，确保二次压力稳定。它用于降低局部回路中的压力。由压力调节元件（1）设定压力retz品牌  DR10DP type valve is a three-way structure direct acting pressure reducing valve, that is, it has overflow function on the pressure reducing side to ensure the stability of the secondary pressure. It is used to reduce the pressure in the local circuit. The pressure is set by the pressure regulating element (1）

在静态位置 该阀常开.油液可自由从油口B流向油口A。油口A的压力经控制油路（4）还作用于压力弹簧（3）对面的小阀芯（9）端面上。当油口的压力达至弹簧（3）的设定压力时 小阀芯（9）推动阀芯（2）移至控制位置 并保持油口A压力恒定。控制阀的油液经控制孔（4）取自油口A。如果油口A的压力由于外力而继续上升.阀芯（2）上的台肩（5）打开.油口Y的油路打开.多余的油液流入油箱以防止压力进一步升高。弹簧腔（6）经油口Y由外部向油箱泄油。The valve is normally open in the static position Fluid can flow freely from port B to port A. The pressure of port A also acts on the end face of the small valve element (9) opposite the pressure spring (3) through the control oil circuit (4). When the pressure of the oil port reaches the set pressure of the spring (3), the small valve element (9) pushes the valve element (2) to the control position and keeps the pressure of the oil port A constant. The oil of the control valve is taken from port A through the control hole (4). If the pressure of port A continues to rise due to external force, the shoulder (5) on the valve element (2) is opened and the oil circuit of port Y is opened Excess fluid flows into the tank to prevent further pressure increases. The spring chamber (6) drains oil from the outside to the oil tank through the oil port Y.

一个可选的单向阀（7）的存在使油液从油口A至油口B自由流动 The presence of an optional check valve (7) allows fluid to flow freely from port A to port BThe presence of an optional check valve (7) allows fluid to flow freely from port A to port B

一个压力表接口（8）.对二次压力进行监测 A pressure gauge interface (8). Monitoring the secondary pressure
