Second safety valve 3, the first safety valve 10 use thread cartridge pattern, in the equipped hole on main valve body 1, point
A1 mouth loops and B1 mouthfuls of loops not with valve group is in parallel, for carrying out overpressure protection.
Flange 7 totally two, is installed on the bottom surface of main valve body 1 that there is provided interface A1, the B1 being connected with oil pump by screw.
Ball valve 6 totally two, be fixed by screws on the surface of main valve body 1 there is provided the interface C1 being connected with the mechanism that comes about,
D1, wherein valve group A1 mouths lead to C1 oral grooves, and B1 mouthfuls lead to D1 oral grooves.
Solenoid directional control valve 2 is two four-way patterns, and the upper end of main valve body 1, its oil inlet and check valve are installed on by screw
The outlet of component 5 is connected, and oil return opening is connected with the drain tap G1 of valve group, and oil-out passes through the internal gutter of main valve body 1 and
Three inserted valves 4, the first inserted valve 9 are connected with the cover plate of the second inserted valve 8, and solenoid directional control valve 2 is provided with operation handle, can be used for
Control manually.
First inserted valve 9, the 3rd inserted valve 4 are fluid-control one-way valve-type inserted valve, and the second inserted valve 8 is substantially unidirectional valve-type
Inserted valve, its plug-in unit is installed in the equipped hole on main valve body 1, and control cover plate is fixed by screws on the surface of main valve body 1.
3rd inserted valve 4 is arranged in the A1-C1 loops of valve group, and the B1-D1 that the second inserted valve 8, the first inserted valve 9 are arranged in valve group is returned
Lu Zhong, and the second inserted valve 8 is also connected with the A1 side loops of valve group.
Check valve assembly 5 includes a mounting blocks and three plug-type one-way valves, is screwed by mounting blocks in master
On the surface of valve body 1, A1, B1 side loop and solenoid directional control valve 2 of the check valve assembly 5 by plug-type one-way valve respectively with valve group
It is connected.
In addition, the leakage hole G1 in valve group uses the pipe joint of national standard.
The hydraulic principle of steering wheel master control valve group is as shown in figure 5, in figure, A1 mouthfuls, B1 mouthfuls of respectively with main oil pump two
Oil-out is connected, and C1 mouthfuls are connected with 1# cylinders, and D1 mouthfuls are connected with 2# cylinders, and G1 mouthfuls are connected with fuel tank.
When the electromagnet of solenoid directional control valve 2 must not be electric, its valve element is in the function position shown in Fig. 5, the He of the 3rd inserted valve 4
Hydraulic control one-way valve in the cover plate of first inserted valve 9 is in the function position of diagram, the 3rd inserted valve 4 and the first inserted valve 9
The two inserted valves are closed, and the path of oil cylinder to oil pump is cut off, and in-oil cylinder fluid can not be discharged, so as to realize
Lock rudder function.Further, since the control oil circuit of the second inserted valve 8 is linked up through solenoid directional control valve 2 and drain tap G1 so that second inserts
Fill valve 8 and be in open mode, such A1 mouthfuls is just directly linked up with B1 mouthfuls, starting without load for motor can be achieved, so as to slow down

When major loop pressure oil by being divided into three tunnels after check valve assembly 5, solenoid directional control valve 2, all the way close the second inserted valve 8,
So as to separate the direct path between A1 mouthfuls and B1 mouthfuls；Remaining two-way promotes the lid of the 3rd inserted valve 4 and the first inserted valve 9 respectively
Fluid-control one-way valve events in plate, make the 3rd inserted valve 4 and the first inserted valve 9 be in open mode, realize A1 mouthfuls and C1 oral grooves
Logical, B1 mouthfuls lead to D1 oral grooves.It is assumed that with the A1 mouthfuls of main oil pump being connected outlet oil extractions, hydraulic oil passes through after left loop
C1 mouthfuls make rudder rotate counterclockwise into 1# cylinders, and the fluid of 2# cylinders discharge then returns to main oil pump by D1 mouthfuls through B1 mouthfuls
Inlet port.Vice versa.
Second safety valve 3 and the first safety valve 10 are set up in design pressure, are caused when due to reasons such as outer load excessives
When B1-D1 lateral pressures exceed setting value, the second safety valve 3 is automatically turned on, and realizes the overpressure protection of B1-D1 sides；When A1-C1 side pressures
When power exceedes setting value, the first safety valve 10 is opened, and realizes the overpressure protection of A1-C1 sides.
Embodiments of the invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Example, in the knowledge that those of ordinary skill in the art possess, can also make on the premise of present inventive concept is not departed from
Go out various change.
