Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings.
It is Combined hydraulic valve framework and different working condition principle schematic referring to Fig. 1, Fig. 2 and Fig. 3, wherein solid line represents
For high-pressure oil passage, dotted line is low pressure oil return circuit, and when solenoid valve valve 1 or 8 is individually powered, power and energy valve is as required
Complete oil circuit handoff functionality.
Fig. 4 describes the spool location technology using radial load control axial displacement, and spool 9 is connected firmly with locating piece 11, fixed
The compression fit of two grooves and steel ball is two operating positions of spool on the block of position.
The present invention a kind of specific embodiment be：Assembled hydraulic control valve is by enabling solenoid valve 1, shutdown solenoid valve 8, shape
State switching valve 3 and control oil circuit A2, output circuit A4, output circuit B6, control oil circuit B7 compositions, actuator is controlled according to instruction
5 open, close or hold, as shown in Figure 1.Enabling solenoid valve 1 and shutdown solenoid valve 8 are small-power normally closed type two-bit triplet electromagnetism
The high pressure of driving condition switching valve is connected in valve when connecting control instruction.State switching valve is two-position four-way pilot operated directional control valve, according to
Spool position variation switches over hydraulic pressure oil inlet, the oil return of drive ram 5.
To ensure that state conversion valve core is stable and reliable in work two operating positions, product holds function and is not shaken by the external world
Dynamic, pressure oscillation and the influence of electric fault are provided with spool positioning device in spool one end.Spool locating piece 11 and spool 9
