(MG,MK)节流阀 单向节流阀

MG/MK系列节流阀/单向节流阀 技术参数 Technical paramete

通径(NG)6至30, 压力至31.5MPa ,流量至400L/min  Diameter (NG) 6 to 30, pressure to 31.5MPa, flow to 400L/min

MG型节流阀 特性 characteristic

该阀双向节流。压力油经侧孔（3）进入由阀体（2）和调节套（1）构成的节流口（4）。旋转调节套（1）可以无级调节节流口（4）的过流截面retz品牌 The valve has two-way throttling. The pressure oil enters the orifice (4) composed of the valve body (2) and the adjusting sleeve (1) through the side hole (3). Rotating the adjusting sleeve (1) can adjust the overflow section of the throttle port (4) steplessly

MK型单向节流阀 特性 characteristic

在阀的节流方向.压力油和弹簧（6）将阀芯（5）压在阀座上. 封闭连通. 压力油通过侧孔（3）进入由阀体（2）和调节套（1）构成的节流口（4）。在相反方向.压力作用于阀芯（5）的锥面上.打开阀口  使压力油无节流地通过单向阀。与此同时，部分压力油液通过环型槽达到所希望的自我清洁效应 In the throttling direction of the valve, the pressure oil and spring (6) press the valve element (5) onto the valve seat Closed connection The pressure oil enters the orifice (4) composed of the valve body (2) and the adjusting sleeve (1) through the side hole (3). In the opposite direction, the pressure acts on the cone of the valve element (5) Open the valve port to allow the pressure oil to pass through the check valve without throttling. At the same time, part of the pressure oil achieves the desired self-cleaning effect through the annular groove.
