Description
Technical field
The present invention relates to a kind of tandem hydraulic loop, a kind of tandem hydraulic loop requiring mechanical synchronization, belong to
Technical field of hydraulic equipment.
Background technology
Mainly directly connected, the most such as with the second hydraulic motor 2 by the first hydraulic motor 1 in current hydraulic series loop
Shown in Fig. 3；Or a joint in parallel with hydraulic motor 1 while the first hydraulic motor 1 is directly connected with the second hydraulic motor 2
Discharge orifice 3, the most as shown in Figure 4.
The former easily causes, due to the impact of hydraulic motor 1 volumetric efficiency, hydraulic motor 2, the phenomenon being emptied；The latter due to
The existence of choke plug does not results in the damage of hydraulic motor, but the flow being raised through restriction being as pressure increases, liquid
Pressure motor 1 forms trend in parallel with hydraulic motor 2, and output speed declines serious.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of tandem hydraulic loop reliably.
The technical scheme provided according to the present invention, a kind of tandem hydraulic loop, including the first hydraulic motor and the second hydraulic pressure
Motor, the outlet of the first hydraulic motor is connected by pipeline with the entrance of the second hydraulic motor；Also include pressure-compensated valve；Described
Pressure-compensated valve is provided with A mouth, B mouth and T mouth, and the entrance of A mouth and the first motor connects, and the entrance of B mouth and the second motor is even
Connecing, T mouth is connected with fuel tank.
Described pressure-compensated valve includes first segment discharge orifice, second section discharge orifice, the 3rd throttle orifice and main valve plug；Described pressure
The A mouth of recuperation valve, B mouth and T mouth are the A mouth of main valve plug, B mouth and T mouth, and main valve plug one end is for controlling end, and the other end is spring
End；
The A mouth of described main valve plug is connected with the import of first segment discharge orifice, the outlet of first segment discharge orifice respectively with the control of main valve plug
End and second section discharge orifice connect；The B mouth of main valve plug and the import of the 3rd throttle orifice connect；The outlet of the 3rd throttle orifice and main valve plug
Spring terminal connected by pipeline.
Beneficial effects of the present invention: present invention achieves a kind of tandem hydraulic loop, add pressure-compensated valve, it is achieved that
The function of moment of torsion distribution, it is to avoid the emptying phenomenon of the second hydraulic motor, will not reduce the output speed of hydraulic motor simultaneously.

Detailed description of the invention
As shown in Figure 1-2: a kind of tandem hydraulic loop, including the first hydraulic motor 1 and the second hydraulic motor 2, the first liquid
The outlet of pressure motor 1 is connected by pipeline with the entrance of the second hydraulic motor 2；Also include pressure-compensated valve 4；Described pressure compensation
Valve 4 is provided with A mouth, B mouth and T mouth, and the entrance of A mouth and the first motor 1 connects, and the entrance of B mouth and the second motor 2 connects, T mouth
It is connected with fuel tank.
Described pressure-compensated valve 4 includes first segment discharge orifice 5, second section discharge orifice the 6, the 3rd throttle orifice 7 and main valve plug 8；Institute
Stating the A mouth of pressure-compensated valve 4, B mouth and T mouth and be the A mouth of main valve plug 8, B mouth and T mouth, main valve plug 8 one end is control end, another
End is spring terminal；
The A mouth of described main valve plug 8 is connected with the import of first segment discharge orifice 5, the outlet of first segment discharge orifice 5 respectively with main valve plug 8
Control end and second section discharge orifice 6 connects；The B mouth of main valve plug 8 and the import of the 3rd throttle orifice 7 connect；The outlet of the 3rd throttle orifice 7
It is connected by pipeline with the spring terminal of main valve plug 8.
When the present invention works, the hydraulic oil in pressure-compensated valve 4 A mouth is respectively through first segment discharge orifice 5 and second section discharge orifice
6 return to T mouth so that the ratio of pressure and A mouth pressure that main valve plug 8 controls end is a constant, and the hydraulic oil in B mouth passes through the 3rd
Throttle orifice 7 acts on the spring terminal of main valve plug 8, and main valve plug 8 is in poised state.When B mouth pressure reduces, main valve plug 8 moves to right,
Hydraulic oil flows to B mouth from A mouth, and B mouth pressure rises to close A mouth, B mouth during equilbrium position；When B mouth pressure raises, main valve plug 8
Moving to left, B oral fluid force feed flows to T mouth, and B mouth pressure closes B mouth, T mouth when dropping to equilbrium position.
