The hydraulic oil for exporting smaller flow from delivery outlet 13 supplies next stage executive component, controls the hydraulic oil of 31 left end of mandrel at this time
It is recovered by the oil groove 1 that draws in 31 left side of channel 1 and control mandrel from oil road 1.
The case where in view of system pressure super large, it is additionally provided with draining road 27 in the adjusting cavity 2, the draining road 27 can be with
21 left end cavity of mandrel is adjusted to communicate.
As shown in figure 5, system pressure super large, a large amount of hydraulic oil for entering input port A11 from double-united oil pump pass through uplink oil
Road 4 is directed to the left end cavity of adjusting cavity 2 and draws in oil groove 2 23, moves right to pole since pressure official post adjusts mandrel 21
Value draws the right end cavity that the hydraulic oil in oil groove 2 23 enters control mandrel 31 by oil duct 26, pushes control mandrel 31 to the left
It moves and closes the oil guide groove 2 33 for controlling 31 middle part of mandrel and transition oil groove 1 and transition oil groove 2 16, and input port
B12 and oil return opening 14 are connected to drain pan 34 simultaneously, so directly being returned from the hydraulic oil that input port B12 enters from oil return opening 14
It receives, the hydraulic oil for controlling 31 left end of mandrel at this time draws oil groove 1 from oil road by 31 left side of channel 1 and control mandrel
One 25 are recovered, and the hydraulic oil adjusted in 21 left end cavity of mandrel is recovered from draining road 27, to play more preferably draining
Effect.
When the system pressure that executive component needs changes, need to adjust the pressure of preloading spring 7, thus by as schemed
Structure shown in 2 realizes adjustment, and 2 right end of adjusting cavity is closed by seal assembly 8, and the seal assembly 8 includes and preload
What 7 right end of spring was connected tightens bar 81, for the fixed flange end cap 82 and locking member 83 for tightening bar 81.Wherein tighten bar 81 with
Flange end cap 82 is threadedly coupled, and rotation tightens bar 81 to adjust it at a distance from preloading spring 7, thus fine-tuning preloading spring 7
To the pretightning force for adjusting mandrel 21.This structure can realize the adjusting to pretightning force under conditions of not having to remove controller, greatly
The use of controller is facilitated greatly.
