Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.
The structure of steering wheel main control valve group of the present invention, as shown in Fig. 4 a, Fig. 4 b, Fig. 4 c, comprising: main valve body 1, solenoid directional control valve 2, second safety valve 3, the 3rd cartridge valve 4, check valve assembly 5, ball valve 6, flange 7, second cartridge valve 8, first cartridge valve 9, first safety valve 10.
Main valve body 1 is for installing each hydraulic valve piece, and its inside has valve member to be equipped with duct and hydraulic oil flow passage.
Second safety valve 3, first safety valve 10 adopts thread cartridge pattern, is arranged in the equipped hole on main valve body 1, in parallel with the A1 mouth loop of valve group and B1 mouth loop respectively, for carrying out overpressure protection.
Flange 7 totally two, is installed on by screw on the bottom surface of main valve body 1, provides the interface be connected with oil pump A1, B1.
Ball valve 6 totally two, is fixed by screws on the surface of main valve body 1, provides the interface be connected with loof mechanism C1, D1, and wherein the A1 mouth of valve group and C1 oral groove lead to, and B1 mouth is logical with D1 oral groove.
Solenoid directional control valve 2 is two four-way patterns, main valve body 1 upper end is installed on by screw, its filler opening is connected with the outlet of check valve assembly 5, return opening is connected with the drain tap G1 of valve group, oil outlet is connected with the cover plate of the second cartridge valve 8 with the 3rd cartridge valve 4, first cartridge valve 9 by the internal gutter of main valve body 1, solenoid directional control valve 2 is provided with operating grip, can be used for Non-follow control.
First cartridge valve 9, the 3rd cartridge valve 4 are fluid-control one-way valve-type cartridge valve, and the second cartridge valve 8 is substantially unidirectional valve-type cartridge valve, and its plug-in unit is installed in the equipped hole on main valve body 1, control cover plate and are fixed by screws on the surface of main valve body 1.3rd cartridge valve 4 is arranged in the A1-C1 loop of valve group, and the second cartridge valve 8, first cartridge valve 9 is arranged in the B1-D1 loop of valve group, and the second cartridge valve 8 is also connected with the A1 side loop of valve group.
Check valve assembly 5 comprises a mounting blocks and three plug-type one-way valves, is screwed at main valve body 1 on the surface by mounting blocks, and check valve assembly 5 is connected with A1, B1 side loop of valve group and solenoid directional control valve 2 respectively by plug-type one-way valve.
In addition, the leakage hole G1 in valve group adopts the pipe joint of GB.
As shown in Figure 5, in figure, A1 mouth, B1 mouth are connected with two oil outlets of main oil pump the hydraulic work principle of steering wheel main control valve group respectively, and C1 mouth is connected with 1# cylinder, and D1 mouth is connected with 2# cylinder, and G1 mouth is connected with fuel tank.
The electromagnet of solenoid directional control valve 2 must not electricity time, its spool is in the function position shown in Fig. 5, Pilot operated check valve in the cover plate of the 3rd cartridge valve 4 and the first cartridge valve 9 is all in illustrated function position, 3rd cartridge valve 4 and these two cartridge valves of the first cartridge valve 9 are in closed condition, oil cylinder is cut off to the path of oil pump, in-oil cylinder fluid cannot be discharged, thus realizes lock rudder function.In addition, because the oil circuit control of the second cartridge valve 8 is linked up with drain tap G1 through solenoid directional control valve 2, make the second cartridge valve 8 be in open mode, such A1 mouth is just directly linked up with B1 mouth, not being with of motor can be realized and carry startup, thus slow down hydraulic shock and the impact to electrical network.
After unit starting, when the electromagnet of solenoid directional control valve 2 obtains electric, spool switches to the work of left function position, and now the pressure oil of major loop is by being divided into three tunnels after check valve assembly 5, solenoid directional control valve 2, one tunnel makes the second cartridge valve 8 close, thus cuts off the direct path between A1 mouth and B1 mouth; All the other two-way promote the fluid-control one-way valve events in the cover plate of the 3rd cartridge valve 4 and the first cartridge valve 9 respectively, make the 3rd cartridge valve 4 and the first cartridge valve 9 be in open mode, and realize A1 mouth and C1 oral groove and lead to, B1 mouth is logical with D1 oral groove.Now suppose that the main oil pump be connected with A1 mouth exports oil extraction, high pressure oil enters 1# cylinder by C1 mouth after left loop makes rudder rotate counterclockwise, and the fluid that 2# cylinder is discharged then gets back to the inlet port of main oil pump through B1 mouth by D1 mouth.Vice versa.
Second safety valve 3 and the first safety valve 10 are all set up in design pressure, when due to outer load is excessive etc. reason makes B1-D1 side pressure exceed setting value time, the second safety valve 3 is opened automatically, realizes the overpressure protection of B1-D1 side; When A1-C1 side pressure exceedes setting value, the first safety valve 10 is opened, and realizes the overpressure protection of A1-C1 side.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
