Passage flow duct outlet be connected, the auxiliary oil inlet of system is connected with the oil inlet of the 3rd reversal valve, in the Median Function of the 3rd reversal valve its
Oil inlet is connected with oil return opening, two actuator ports of a second reversal valve different actuator port also respectively from the 3rd reversal valve
It is connected, the middle passage flow duct outlet of three oil return openings and the 3rd reversal valve of reversal valve is connected with system oil return mouthful.
The auxiliary oil inlet flow of system of the invention is less than the main oil inlet flow of system；When using, by individually operated three
Reversal valve can respectively realize the rotation of drilling rod, the function that advance and retreat, middling speed are retreated at a slow speed, while operating the second reversal valve and the 3rd to change
To valve, Dual-pump flow-converging is capable of achieving, is capable of achieving fast advance and retreat, have the advantages that function is more, easy to operate, and it is energy-efficient, reduce
Operating cost.
As a further improvement on the present invention, the guiding valve of three reversal valve with respective oil inlet and two actuator ports pair
The axle journal both sides answered are equipped with throttling channel；Smoothness of the guiding valve when different station is changed can be improved, fretting performance is improved；
As a further improvement on the present invention, it is provided with relief valve between an actuator port and oil return opening of the first reversal valve；
Drilling rod can carry out repairing when rotating, occur being emptied at a high speed；
As a further improvement on the present invention, it is provided with safety valve between the main oil inlet of system and system oil return mouthful；
In sum, the present invention has the advantages that function is more, easy to operate, and energy-efficient, reduces operating cost.

Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Figures 1 to 4, the Dual-pump flow-converging rig valve of the embodiment is burst integrated morphology, including by bolt phase
The oil inlet and oil return valve body 1 of connection, the first reversal valve 2, the second reversal valve 3, the 3rd reversal valve 4 and connection valve body 5, oil inlet and oil return valve body 1 set
There is the main oil inlet 6 of system（P）With 7 (T) of system oil return mouthful, safety valve is provided between the main oil inlet 6 of system and system oil return mouthful 7
8, the 3rd reversal valve 4 is provided with the auxiliary oil inlet 9 (P1) of system, and the first reversal valve 2, the second reversal valve 3 and the 3rd reversal valve 4 are three
Position six-way transfer valve, the middle passage flow duct of three reversal valves is sequentially connected in series, and the main oil inlet 6 of system is through-flow with the first reversal valve 2
Road import and oil inlet are connected, and relief valve 10 is provided between the actuator port A1 and oil return opening of the first reversal valve 2；Second changes
It is connected with the middle passage flow duct outlet of the first reversal valve 2 to the oil inlet of valve 3, the oil-feed of the auxiliary reversal valve 4 of oil inlet 9 and the 3rd of system
Mouthful be connected, its oil inlet is connected with oil return opening in the Median Function of the 3rd reversal valve 4, the actuator port A2 of the second reversal valve 3 and
The actuator port A3 of the 3rd reversal valve 4 is connected, the actuator port B2 of the second reversal valve 3 and actuator port B3 of the 3rd reversal valve 4
It is connected, the middle passage flow duct outlet of three oil return openings and the 3rd reversal valve 4 of reversal valve is connected with system oil return mouthful 7；Three commutations
The guiding valve 11 of valve is equipped with throttling channel 12 in axle journal both sides corresponding with respective oil inlet and two actuator ports；
When using, the main oil inlet 6 of system is connected with main pump, and the auxiliary oil inlet 9 of system is connected with auxiliary pump, and the auxiliary oil inlet flow of system is small
In the main oil inlet flow of system, two actuator port A1 of three reversal valves and B1, A2 and B2, A3 and B3 respectively with three working oils
