As shown from the above technical solution, this utility model connects the first hydraulically-controlled one-way valve and the second hydraulically-controlled one-way valve by threeway, first hydraulically-controlled one-way valve and the second hydraulically-controlled one-way valve connect two kinds of different hydraulic power supplies by oil pipe, due to the first hydraulically-controlled one-way valve and the effect of the second hydraulically-controlled one-way valve built-in cut-off spool, two kinds of different hydraulic power supplies are the most non-interference.The advantage that hydraulic bidirectional check valve assembly of the present utility model has simple in construction, good reliability, low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
A kind of hydraulic bidirectional check valve assembly for steering wheel as shown in Figure 1, including first hydraulically-controlled one-way valve the 1, second hydraulically-controlled one-way valve 2 and the threeway 3 connecting both, the oil-out of the first hydraulically-controlled one-way valve 1 and the second hydraulically-controlled one-way valve 2 is connected with the first oil-in and second oil-in of threeway 3 respectively, the hydraulic power supply that the oil-in of the first hydraulically-controlled one-way valve 1 and the second hydraulically-controlled one-way valve 2 is different from two kinds respectively is connected, the inside of the first hydraulically-controlled one-way valve 1 and the second hydraulically-controlled one-way valve 2 is provided with cut-off spool, and the oil-out of threeway is connected with steering wheel.
Further, the first hydraulically-controlled one-way valve 1 and the second hydraulically-controlled one-way valve 2 are symmetrical arranged.Namely the first hydraulically-controlled one-way valve 1 and the second hydraulically-controlled one-way valve 2 are separately positioned on the two ends of threeway rectilinear direction.
Further, being threaded connection between the first oil-in and the oil-out of the first hydraulically-controlled one-way valve 1 of threeway 3, the first hydraulically-controlled one-way valve 1 is provided with screw, and threeway 3 is provided with the external screw thread matched with screw.Two ports of namely threeway 3 rectilinear direction are respectively equipped with external screw thread, are used in mating connection with the screw of the first hydraulically-controlled one-way valve 1 and the second hydraulic pressure single valve 2.
Further, the copper sealing ring 4 of sealing it is provided with between first hydraulically-controlled one-way valve 1 and threeway 3, copper sealing ring 4 matches with the external screw thread of threeway 3, and the external screw thread of threeway 3 is provided with the jam nut 5 compressing copper sealing ring 4, and copper sealing ring 4 is arranged between jam nut 5 and the first hydraulically-controlled one-way valve 1.The most first jam nut 5 is screwed into the externally threaded inner terminal of threeway 3, then copper sealing ring 4 is put on external screw thread, again the oil-out of the first hydraulically-controlled one-way valve 1 is screwed on the external screw thread of threeway 3, after screwing in certain depth, reversely turn jam nut 5, make copper sealing ring 4 be close on the end face of the first hydraulically-controlled one-way valve 1, increase pretightning force, play sealing function.The structure of the second hydraulically-controlled one-way valve 2 is identical with the first hydraulically-controlled one-way valve 1 with installation, does not repeats them here.
Operation principle of the present utility model is as follows:
As shown in Figure 2, two different hydraulic power supplies provide hydraulic oil to steering wheel under different conditions, the hydraulic oil of one of which hydraulic power supply enters from the oil-in of the first hydraulically-controlled one-way valve, through threeway, and from the oil-out approach axis machine of threeway vertical end, at this moment entering the hydraulic oil in threeway can not be from the second hydraulically-controlled one-way valve output, because the inside of the second hydraulically-controlled one-way valve is provided with cut-off spool；Otherwise, during the second hydraulically-controlled one-way valve input hydraulic oil, also pass through threeway and from the oil-out approach axis machine of threeway, now, the cut-off spool in the first hydraulically-controlled one-way valve plays cut-off effect.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
