插装式调压阀，阀体为通孔结构，阀体底部端面采用收口方式，节流块镶嵌在阀体的阀孔底端，阀芯安装于阀体的阀孔内，弹簧安装于阀芯后面，在弹簧后面装有调压螺钉和锁紧螺母，阀体的外圆柱上装有“O”型密封圈；阀体轴向的中段设有两组进油孔A，阀体孔口端设有一组与润滑油路连通的润滑油输出孔C，在节流块与进油孔A之间设有一组径向的回油孔D，节流块上有1个感应孔B，进油孔A和感应孔B与控制油路相连通，控制油路的油液通过感应孔B对阀芯一端产生推压作用力，并与阀芯另一端的弹簧作用力形成动态平衡，当油路的油压不同时，阀芯处在对应的不同位置，由阀芯对进油孔A与润滑油输出孔C、进油孔A与回油孔D之间的开度进行管理。 Cartridge valve, the valve for the through-hole structure, the bottom end surface of the valve shut ways using throttling blocks embedded in the body of the valve hole at the bottom, mounted on the valve spool valve hole in the valve spring installed behind the core, in the back of the spring fitted with a pressure screw and locknut, equipped with "O"-ring on the outer cylindrical body; the middle of the body is provided with two axially into the hole A, the valve orifice end There is a set of output ports C and lubricating oil path communicating between the block and the oil inlet orifice has a radial A return hole D, there is a throttle sensor holes on the block B into the oil A bore hole B and the induction passage communicates with the control, the control fluid passage through the valve body end of the sensor hole B of the pressing force generated, and the dynamic balance with the spring force of the valve body is formed at the other end, when the passage The oil is not the same in different positions corresponding to the valve body, the valve body into the hole of the output ports A and oil C, and the inlet opening of the oil return hole A hole D between management.
