The utility model has the advantages of simple structure, conveniently switch oil transportation direction and carry out the pressurize to the oil circuit.
Description
Technical field
The utility model relates to a kind of hydraulic equipment, particularly relates to a kind of supporting oil cylinder valve block assembly.
Background technique
In impeller dynamic test, one of them important test event is placed in super sized type water tank by guide plate to test.This superhuge water tank, wide 3 meters, long 6 meters, weigh 132 tons when storing full water.In test process, water tank can require to fall after rise to ground in the flat surface from surface uplift to 3.2m and from flat surface, after being lifted to ground, needs to support this water tank.
For this reason, claimant expects adopting hydraulic way to support water tank, and this just needs to use valve block assembly, should switch hydraulic oil outbound course, also to ensure in addition can carry out pressurize to support cylinder after support cylinder supports water tank, avoid water tank to fall vibrations after rise.Also in prior art, also there is no this valve block assembly at present.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of supporting oil cylinder valve block assembly, can switch hydraulic oil outbound course, can also carry out pressurize after support cylinder supports fuel tank to hydraulic jack, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of supporting oil cylinder valve block assembly, is characterized in that: comprise valve block, is arranged on solenoid directional control valve and the first equilibrium valve, the second equilibrium valve and stop valve in valve block;
Described valve block has oil-feed P, fuel-displaced A mouth, fuel-displaced B mouth, pressurize O mouth and oil return T mouth;
Described oil-feed P mouth connects the first hydraulic fluid port of described solenoid directional control valve, second hydraulic fluid port of described solenoid directional control valve connects described fuel-displaced A mouth through described first equilibrium valve, 3rd hydraulic fluid port of described solenoid directional control valve is communicated with the filler opening of described fuel-displaced B mouth and described stop valve through described second equilibrium valve, 4th hydraulic fluid port of described solenoid directional control valve is communicated with described oil return T mouth, and the oil outlet of described stop valve connects described pressurize O mouth.
Adopt technique scheme, in use, fuel-displaced A mouth and fuel-displaced B mouth are respectively used to the reverse hydraulic fluid port and the forward hydraulic fluid port that are connected support cylinder; Pressurize O mouth is for connecting accumulator.Like this, can be switched hydraulic oil outbound course by solenoid valve selector valve, thus drive support cylinder to rise and decline; After support cylinder supports water tank, pressurize can be carried out to hydraulic jack by accumulator, avoid water tank to fall vibrations after rise.
In addition, valve block also has detection M mouth and detection N mouth, described first equilibrium valve is also communicated with described detection M mouth, and described second equilibrium valve is also communicated with described detection N mouth; Described detection M mouth and described detection N mouth are all connected with pressure transducer.So just can the hydraulic fluid pressure exported be detected.
Therefore, the utility model has simple, the convenient advantage switching oil transportation direction and oil circuit is carried out to pressurize of structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is hydraulic schematic of the present utility model.
Embodiment
As shown in Figure 1, supporting oil cylinder valve block assembly of the present utility model, comprises valve block (in figure shown in dotted line), is arranged on solenoid directional control valve 162 and the first equilibrium valve 291, second equilibrium valve 292 and stop valve 251 in valve block;
Valve block has oil-feed P, fuel-displaced A mouth, fuel-displaced B mouth, pressurize O mouth, oil return T mouth, detection M mouth and detection N mouth.
Oil-feed P mouth connects the first hydraulic fluid port of solenoid directional control valve 162, second hydraulic fluid port of solenoid directional control valve 162 connects fuel-displaced A mouth through the first equilibrium valve 291,3rd hydraulic fluid port of solenoid directional control valve 162 is communicated with the filler opening of fuel-displaced B mouth and stop valve 251 through the second equilibrium valve 292,4th hydraulic fluid port of solenoid directional control valve 162 is communicated with oil return T mouth, and the oil outlet of stop valve 251 connects pressurize O mouth.
Adopt technique scheme, in use, fuel-displaced A mouth and fuel-displaced B mouth are respectively used to the reverse hydraulic fluid port and the forward hydraulic fluid port that are connected support cylinder 21; Pressurize O mouth is for connecting accumulator 26.Like this, can be switched hydraulic oil outbound course by solenoid valve selector valve 162, thus drive support cylinder 21 to rise and decline; After support cylinder 21 supports water tank, pressurize can be carried out to hydraulic jack 21 by accumulator 26, avoid water tank to fall vibrations after rise.
First equilibrium valve 291 is also communicated with detection M mouth, and the second equilibrium valve 292 is also communicated with described detection N mouth; Detection M mouth and detection N mouth are all connected with pressure transducer 14.So just can the hydraulic fluid pressure exported be detected.
Can be found out by foregoing detailed description, the utility model has simple, the convenient advantage switching oil transportation direction and oil circuit is carried out to pressurize of structure.
