Embodiment
Below against attached drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
As shown in Figure 1, a kind of hydraulic system super-pressure control unit, using 2 solenoid valves, cartridge insertion direction valve 2, unidirectional increasing
What depressor 5 integrated, the solenoid valve uses four-way electromagnetic reversing valve, and four-way electromagnetic reversing valve has A, B, P, T tetra-
Logical hydraulic fluid port, hydraulic pump coming oil, solenoid valves, lead to oil, hydraulic oil is arrived by spool the commutation PB, AT of four-way electromagnetic reversing valve I 1
Up to cartridge insertion direction valve 2, spool is opened at this time, and a part of hydraulic oil is sent to hydraulic system or detection device, some liquid
Pressure oil assigns to unidirectional booster 5, promotes the spool of unidirectional booster 5 to go downwards to bottom, and four-way electromagnetic reversing valve II 4 obtains electric at this time
Afterwards, hydraulic oil leads to oil by spool the commutation PB, AT of four-way electromagnetic reversing valve II 4, and hydraulic oil also reaches the bottom of unidirectional booster 5
Portion, because the spool area of unidirectional booster 5 is different, the spool of unidirectional booster 5 moves up at this time, forms high pressure.
