Spatially perpendicular, oil duct 507 is extends in the 4th light bar segment 504 since in the second light bar segment 502 of valve rod, oil duct
507 set multiple and multiple oil ducts 507 to be uniformly distributed circumferentially on the periphery of valve rod.Small valve core in original state
10 and big valve core 9 be in contact realization sealing so that locked cavity is not connected with the hollow cavity 604 of swivel nut 6, into locked cavity
High-voltage oil liquid is flowed at small valve core 10 by oil duct 507, and then high-voltage oil liquid promotes small valve core 10 axially towards close to spiral shell
The direction of set 6 is moved, and small valve core 10 is separated with big valve core 9, depressurization.
As shown in Fig. 1, Fig. 3, Fig. 5 and Fig. 6, swivel nut 6 is both ends open, the cylinder of inner hollow, and swivel nut 6 is included along axis
To the guide section 601 set gradually and spacing section 602, guide section 601 and spacing section 602 are cirque structure and guide section
601 and spacing section 602 to be fixedly and coaxially connected, the inner cavity of guide section 601 is accommodates the hollow of valve core spring 11 and small valve core 10
Inner cavity 604, internal thread hole 603 are arranged at spacing section 602 of inside center, and internal thread hole 603 is connected with hollow cavity 604,
Valve rod is inserted into internal thread hole 603 after passing through hollow cavity 604.The overall diameter of guide section 601 is less than spacing section 602
Overall diameter, the interior diameter of guide section 601 is more than the diameter of the 4th light bar segment 504, and big valve core 9 is sheathed on guide section 601, leads
Guiding role is played to 601 pairs of big valve cores 9 of section, guide section 601 is inserted into the hollow cavity of big valve core 9, and big valve core 9 is sheathed on valve
In 3rd light bar segment 503 of bar and the guide section 601 of swivel nut 6, valve rod and swivel nut 6 are engaged jointly to moveable big valve core 9
Play guiding role so that the operation of big valve core 9 is more stable, and big valve core 9 can be born larger when hydraulic control one-way valve is opened
Oil shocking, work are more reliable.And swivel nut 6 is inserted into the inside of big valve core 9, and other components are not arranged outside big valve core 9, when
When being flowed in into the high-voltage oil liquid in locked cavity towards 9 place cavity of big valve core, high-voltage oil liquid flows through the appearance of big valve core 9
Face, can reduce liquid resistance, so as to set smaller 3 inner cavity of valve body to can be achieved with bigger flow.Valve core spring 11
It is inserted into the hollow cavity 604 of swivel nut 6, valve core spring 11 is simultaneously clipped between spacing section 602 and small valve core 10, and valve core spring 11 is
Cylindrically coiled spring and valve core spring 11 are compression spring, and one end of valve core spring 11 contradicts small valve core 10, valve core spring 11 it is another
End contradicts spacing section 602, and valve core spring 11, which is used to apply small valve core 10, makes small valve core 10 axially towards the side away from swivel nut 6
To being moved, the reset of small valve core 10 and big valve core 9 is realized, and then realize the closing of hydraulic control one-way valve.11 He of valve core spring
Valve rod spring 12 is engaged, and after highly pressurised liquid stops entering in locked cavity, valve rod can be rapid under the action of two-stage spring
Reset, so as to reduce the pressure loss and pressure oscillation.One is formed between spacing section 602 and guide section 601 to removable
Big valve core 9 play the limited step of position-limiting action, under the guiding role of valve rod and guide section 601, when big valve core 9 is subject to liquid
When pressure acts on, big valve core 9 is moved relative to valve rod and big valve core 9 is directed away from the direction of valve pocket 7 and is moved, high pressure
Fluid enters locked cavity, is contacted if big valve core 9 is moved to spacing section 602, and big valve core 9 stops moving relative to valve rod.Valve
A step is formed between second light bar segment 502 of bar and the 3rd light bar segment 503, the diameter of the second light bar segment 502 is more than big valve
The diameter of the centre bore of core 9, when valve rod is moved axially towards the direction away from connector 4, the second light bar segment 502 is used for
Big valve core 9 is promoted to be moved axially towards the direction away from valve seat 19 so that big valve core 9, small valve core 10 are synchronous with valve rod
