(DR6DP...5X)进口直动式减压阀 功能说明 Function description

DRGDP型阀是三通结构直动式阀.即在减压侧具有溢流功能.确保二次压力稳定。它用于回路减压.由压力设定元件（4）设定压力retz品牌 DRGDP type valve is a three-way direct acting valve, which has overflow function at the pressure reducing side to ensure the stability of the secondary pressure. It is used for circuit decompression. The pressure is set by the pressure setting element (4)

在静态位置.该阀常开.油液可自由地从油口P流向油口A。油口A的压力经控制油路（6）还作用于压缩弹簧（3）对面的阀芯（2）的端面。当油口A的压力达到弹簧（3）设定值时，阀芯（2）移至控制位置，油口压力保持恒定。控制阀的油液经控制孔（6）取自油口A。如果油口A的压力由于外力作用继续升高，阀芯（2）继续向压缩弹簧（3）方向移动。这就导致油路经控制阀芯（2）的台肩（8）打开，多余的油液流回油箱.以防止压力进一步提高。弹簧腔经油口T（P）由外部排油回油箱 In the static position, the valve is normally open The oil flows freely from port P to port A. The pressure of port A also acts on the end face of the valve element (2) opposite the compression spring (3) through the control oil circuit (6). When the pressure at port A reaches the set value of the spring (3), the spool (2) moves to the control position and the port pressure remains constant. The oil of the control valve is taken from port A through the control hole (6). If the pressure of port A continues to increase due to external force, the valve element (2) continues to move towards the compression spring (3). This causes the oil circuit to open through the shoulder (8) of the control valve element (2), and the excess oil flows back to the oil tank to prevent the pressure from further increasing. The spring chamber returns to the oil tank from the external oil drain through the oil port T (P).

一个可选的单向阀（5）的存在  允许从油口A至油口P反向流动 The presence of an optional check valve (5) allows reverse flow from port A to port P

一个压力表接口（1）.对二次压力进行监测 A pressure gauge interface (1). Monitoring the secondary pressure
