Abstract
The invention discloses a high-precision synchronous control oil cylinder valve block device. The valve block device comprises a valve block body, wherein an electromagnetic reversing valve, a first balance valve and a second balance valve are arranged in the valve block body, and the valve block body is provided with an oil inlet P, an oil outlet A, an oil outlet B and an oil return opening T; the oil inlet P is communicated with a first oil port of the electromagnetic reversing valve, a second oil port of the electromagnetic reversing valve is communicated with the oil outlet A through the first balance valve, a third oil port of the electromagnetic reversing valve is communicated with the oil outlet B through the second balance valve, and a fourth oil port of the electromagnetic reversing valve is communicated with the oil return opening T. The oil cylinder valve block device has the advantages of being simple in structure, the oil conveying direction is convenient to switch, and the air suction phenomenon of an oil path is prevented.
Description
Technical field
The present invention relates to a kind of hydraulic test, relate in particular to a kind of oil cylinder valve block of high-precise synchronization controlDevice.
Background technology
In impeller dynamic test, one of them important test event is that flow deflector is placed into ultra-large typeIn water tank, test. This superhuge water tank, wide 3 meters, long 6 meters, holding the situation of full waterUnder weigh 132 tons. In test process, water tank can require in the flat surface from surface uplift to 3.2mWith fall after rise to ground from flat surface, and by water tank large and heavy this span from surface uplift to flatOn face, be very difficult thing, and require in the process promoting, water tank has not allowed skew, otherwiseWater tank will be blocked by track, cannot continue lifting, even can cause the damage of water tank.
Afterwards, someone expected utilizing screw body to promote the lifting of this super large jumbo. AlthoughUtilize screw body to carry out lifting and have advantages of that precision is high, can avoid super large jumbo in liftingIn process, be not offset, but the power that screw body can provide is limited, can not reaches lifting super largeThe power that jumbo is required, therefore, finally utilizes screw body to carry out this super large jumbo of liftingOr cannot realize.
Afterwards, applicant expected utilizing the mode of hydraulic pressure to carry out this super large jumbo of lifting, for realizingThe lifting of jacking cylinder, oil circuit must switch oil transportation direction, and in addition, jacking cylinder is doing accompany movementTime, also to prevent and treat and occur emptying phenomenon.
Therefore, be necessary to provide a kind of oil cylinder valve block device that can realize above-mentioned functions.
Summary of the invention
It is packaged that technical problem to be solved by this invention is to provide a kind of oil cylinder valve of high-precise synchronization controlPut the deficiency existing to overcome prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
An oil cylinder valve block device for high-precise synchronization control, is characterized in that: comprise valve block and establishSolenoid directional control valve in valve block, the first balanced valve, the second balanced valve;
Described valve block has oil-feed P mouth, fuel-displaced A mouth, fuel-displaced B mouth and oil return T mouth;
Described oil-feed P mouth is communicated with the first hydraulic fluid port of described solenoid directional control valve, of described solenoid directional control valveTwo hydraulic fluid ports are communicated with described fuel-displaced A mouth, the 3rd hydraulic fluid port of described solenoid directional control valve through described the first balanced valveBe communicated with described fuel-displaced B mouth through described the second balanced valve, the 4th hydraulic fluid port of described solenoid directional control valve is communicated with instituteState oil return T mouth.
In described valve block, be also provided with the first stop valve and the second stop valve, also warp of described the first balanced valveDescribed the first stop valve is communicated with described oil return T mouth, and described the second balanced valve is also through described the second stop valveBe communicated with described oil return T mouth. By increasing the first stop valve and the second stop valve, follow at jacking cylinderWith when motion, by opening the first stop valve and the second stop valve can avoid occurring emptying phenomenon.
Described valve block also has the M of detection mouth, surveys N mouth, described in described the first balanced valve is also communicated withSurvey M mouth, described the second balanced valve is also communicated with described detection N mouth; Described detection M mouth and described spySurvey N mouth and be all connected with pressure sensor. So just can survey the hydraulic fluid pressure of output.
Adopt technique scheme, that the present invention has is simple in structure, conveniently switch oil transportation direction and preventThere is the advantage of emptying phenomenon in oil circuit.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is valve block structure schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, the oil cylinder valve block device of high-precise synchronization control of the present invention, comprises valve block(in figure shown in dotted line) and be located at solenoid directional control valve in valve block 161, the first balanced valve 291,Two balanced valves 292, the first stop valve 311, the second stop valve 312;
Valve block has oil-feed P mouth, fuel-displaced A mouth, fuel-displaced B mouth, survey M mouth, survey N mouth andOil return T mouth. Fuel-displaced A mouth and fuel-displaced B mouth are respectively used to be connected the reverse hydraulic fluid port of jacking cylinder 20 and justTo hydraulic fluid port.
Oil-feed P mouth is communicated with the first hydraulic fluid port of solenoid directional control valve 161, the second oil of solenoid directional control valve 161Mouth is communicated with fuel-displaced A mouth through the first balanced valve 291, and the 3rd hydraulic fluid port of solenoid directional control valve 161 is flat through secondWeighing apparatus valve 292 is communicated with fuel-displaced B mouth, and the 4th hydraulic fluid port of solenoid directional control valve 161 is communicated with oil return T mouth.
The first balanced valve 291 is also communicated with oil return T mouth through the first stop valve 311, the second balanced valve 292Also be communicated with oil return T mouth through the second stop valve 312. By increasing the first stop valve 311 and the second cut-offValve 312, in the time that jacking cylinder 20 does accompany movement, by opening the first stop valve 311 and second sectionOnly valve 312 can avoid occurring emptying phenomenon.
The first balanced valve 291 is also communicated with surveys M mouth, and the second balanced valve 292 is also communicated with surveys N mouth;Survey M mouth and survey N mouth all for Bonding pressure sensor 146. So just can be to valve block assemblyThe hydraulic fluid pressure of output is surveyed.
Can find out by foregoing detailed description, that the present invention has is simple in structure, the convenient oil transportation side of switchingTo with prevent that the advantage of emptying phenomenon from appearring in oil circuit.
