Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of fluid pressure type automatic adjusting balance valve group, and as shown in Figure 1, 2, it includes valve block 1, pressure reducing valve
2, the top of the first hydraulic control one-way valve 31 and the second hydraulic control one-way valve 32, valve block 1 is equipped with the first hydraulic control one-way valve 31 and the second liquid
Control check valve 32；The bottom end of valve block 1 is equipped with pressure reducing valve 2；The explosion relief Y of pressure reducing valve 2 is located at the top of valve block 1；The side of valve block 1
The first oil inlet BL of the first hydraulic control one-way valve 31, the second oil inlet BR of the second hydraulic control one-way valve 32 and oil cylinder are offered respectively
Low pressure repairing mouth P.As shown in figure 3, the pressure that the first hydraulic control one-way valve 31 and the second hydraulic control one-way valve 32 pass through low pressure repairing mouth P
Power oil is opened, and to be connected to the first oil inlet BL and the second oil inlet BR, realizes that the fluid inside oil cylinder flows freely；Pressure reducing valve 2
The fluid of oil cylinder internal losses is supplemented；The explosion relief Y of pressure reducing valve 2 is used for discharging the fluid of 2 spring cavity of pressure reducing valve.
Vehicle bridge is withstood with oil cylinder and be connected with control room in vehicle bridge, when road surface is uneven in driving process, conduction
To oil cylinder, then by the stroke of the valve group control cylinder horizontality is in adjust control room.The valve group is by pressure reducing valve 2, first
Hydraulic control one-way valve 31 and the second hydraulic control one-way valve 32 composition, wherein the first oil inlet BL of the first hydraulic control one-way valve 31 and the second liquid
Second oil inlet BR of control check valve 32 is connected, and makes mutually can quickly compensate between oil cylinder, to reach adjust automatically behaviour
Control the balance of room；Pressure reducing valve 2 is mainly used for the repairing of oil cylinder, and low-pressure can reduce impact, control room can be made to feel in this way
It is more comfortable.
As shown in figure 4, the first hydraulic control one-way valve 31 and the second hydraulic control one-way valve 32 include ball valve core 301, poppet valve core
302, main valve plug 303, valve seat 304 and guide piston 305, ball valve core 301, poppet valve core 302 and main valve plug 303 and 304 phase of valve seat
Cooperation；The center push rod 306 and main valve plug 303 of poppet valve core 302 are matched with guide piston 305.
The operation principle of first hydraulic control one-way valve 31 and the second hydraulic control one-way valve 32 is：Ball valve core 301 and poppet valve core 302 exist
It is kept in contact and seals with valve seat 304 under the action of spring force.When 1 mouthful of pressure is greater than or equal to 2 mouthfuls of pressure, valve will be protected
Hold sealing；When pressure and spring force the sum of of 2 mouthfuls of the pressure more than 1 mouthful, valve mouthful will be opened from 2 mouthfuls to 1.In order to enable fluid
Reverse flow, it is necessary to there is pressure oil to act on 3 mouthfuls.When reaching required pilot pressure for 3 mouthfuls, guide piston 305 acts on
The center push rod 306 of poppet valve core 302 pushes ball valve core 301 to lift off a seat 304, the high-voltage oil liquid of 1 mouthful of release, since guide lives
The area of plug 305 is more much bigger than ball valve core 301, so only needing lower pilot pressure that can open, to reduce energy consumption.By
It is decreased in 1 mouthful of load pressure, therefore lower pilot pressure is only needed just guide piston 305 can be made easily to push main valve
Core 303 lifts off a seat 304, and fluid is allowed to flow to 2 mouthfuls from 1 mouthful.There are two pilot ratios for the valve, are big first when ball valve core 301 acts
Ratio is led, the response of valve release of pressure can be made sensitive, energy saving；Pilot ratio is small when spool 303 acts, and keeps valve events stable, reliable.
In the present embodiment, pressure reducing valve 2 be the first oil inlet BL and the second oil inlet BR supplements needed for pressure oil, can be with
It is effectively matched with vehicle, keeps automatic adjusting balance performance more stable.
Limiting the scope of the invention, those skilled in the art should understand that, in technical scheme of the present invention
On the basis of, the various modifications or variations that can be made by those skilled in the art with little creative work still the present invention's
Within protection domain.
