Pilot valve structure and working principle
 
In the hydraulic system, when a pump to several executive components to supply oil, and the executive components required by the working pressure is not the same situation, can be in the working pressure lower than the pump oil supply pressure branch oil circuit in series a reducing valve, oil flow through the reducing valve, the pressure will be reduced to a certain value, and maintain constant. This kind of pressure reducing valve is called constant value pressure reducing valve.
 
There are direct pressure relief valve and pilot type of two. The working principle of the direct acting type pressure-reducing valve and the direct acting type overflow valve are basically the same, but also through the action in the spool of hydrostatic pressure and spring force phase balance, the principle of comparison, to promote the movement of the spool and change the size of the valve mouth to adjust the output. However, the output of the pressure reducing valve is LJ pressure, not the inlet pressure. Under the normal condition that the pressure reducing valve has no decompression effect, the valve mouth is fully open, and the pressure reducing valve is closed down. The smaller the valve is closed, the greater the decompression amount will be.
 
When the output pressure of the reducing valve is high or the flow is large, the pressure regulating spring is used for direct pressure regulation, then the spring stiffness must be large, when the flow changes, the output pressure fluctuation is large, the size of the valve structure will increase. In order to overcome these shortcomings can be used in the pilot valve. FIG. 3-33 shows the structure and working principle of the pilot reducing valve. FIG. 1-14 shows the spool and spring of the main valve. 6, 8 foot pilot valve spool and spring, the diagram shows the main valve core and the valve sleeve sink groove formed between the pressure relief port in full open state. Oil inlet P, through the pressure relief port, then through the spool on the radial, axial (not shown) oil 13 external control port; 14. A main valve reset spring; 15 one valve body hole flows from the outlet, and the outlet pressure is P:. The outlet pressure ACTS on the pilot valve after passing through the damping hole 2. When the pressure (set as P :) on the pilot valve reaches the setting pressure of the pilot valve, the pilot valve opens, and a control flow flows through the damping hole 2, generating pressure difference. This differential pressure ACTS on both ends of the main valve spool and balances with the main valve spring. When the pressure difference is greater than the pre-tightening force of the main valve spring, the main valve spool moves up and closes the small valve port to reduce the pressure P to P:. The larger the flow (pilot flow) on the damping hole is, (P. P :) the larger the main spool is, the greater the unbalanced force it is exposed to, the larger the lifting capacity of the spool is, the smaller the pressure relief port is closed, and the more obvious the pressure relief effect is. Therefore, the size of the relief port can be automatically adjusted by the main spool to maintain the outlet pressure P. Constant.
