As shown in fig. 1 and 4, the one-way overflow combination valve includes a combination valve body 41 with one end extending into the shuttle valve hole, and a one-way valve and an overflow valve are coaxially arranged in the combination valve body 41. The check valve comprises a check valve core 42 installed in the combined valve body 41, the end part of the shuttle valve core 31 extends into the combined valve body 41 and is close to the check valve core 42, a check valve seat is installed in the combined valve body 41 outside the check valve core 42, and a check valve return spring 43 is installed between the check valve core 42 and the check valve seat; the combined valve body 41 is provided with an oil passing hole a44 communicating the oil duct AC21 with the oil inlet end of the one-way valve, and the combined valve body 41 is also provided with an oil passing hole b45 communicating the oil path A14 with the oil outlet end of the one-way valve cavity.

The one-way valve seat is also used as a conical valve seat 51 of the overflow valve, a conical valve hole communicated with an inner cavity of the one-way valve core 42 is arranged in the conical valve seat 51, a conical valve core 52 with one end extending into the conical valve hole is arranged in the combined valve body on the outer side of the conical valve seat 51, a plug 53 is arranged at the opening end of the combined valve body 41 in a sealing manner, and an overflow return spring 54 is arranged between the conical valve core 52 and the plug 53; an overflow cavity 55 is arranged between the conical valve seat 51 and the plug 53, and an overflow hole 46 for communicating the overflow cavity 55 with the oil passage TA25 is arranged on the combined valve body 41.
The one-way overflow combination valve and the shuttle valve core 31 have the functions of an overload valve, a one-way valve and a hydraulic lock as a whole, the design that the traditional hydraulic lock has no overload function is broken through, the function that the traditional overload valve can not realize the hydraulic lock is also broken through, and a novel composite function valve with overload and high-response locking functions is realized. Unlike conventional overload valves and hydraulic locks: the single-side overload valve and the single-side hydraulic lock are coaxially designed integral plug-in components and are independently integrated into a whole, the outer side of the single-side overload valve is an overload function, the inner side of the single-side overload valve is a one-way hydraulic lock or a one-way valve, but the two functions are integrated into a brand new structure, the design that the traditional hydraulic lock does not have the overload function is broken through, the function that the traditional overload valve cannot realize the hydraulic lock is broken through, and a novel valve with the composite function of the overload function and the high-response locking function is realized. The hydraulic locking part of the combination valve has an oil supplementing function, and under the condition that the oil way A14 or the oil way B15 is overloaded, the oil way B15 or the oil way A14 can complete oil supplementing through an oil passage TB26 → an oil passage BC22 → an oil passage B15 or an oil passage TA25 → an oil passage AC21 → an oil passage A14 under oil return resistance.
When the oil port P passes through the oil path A14, the oil path communicated with the oil path A14 compresses a right spring of the shuttle valve core 31 through the shuttle valve core 31 and opens a right hydraulic lock to complete the functional action. When the oil port P leads to the oil path B15, the oil path B15 compresses the spring through the shuttle spool 31 and opens the left hydraulic lock to complete the functional action.
When the main valve rod 13 is located at the neutral position, oil passage AP23 and oil passage AC21 are not communicated, oil passage BP24 and oil passage BC22 are not communicated, oil passage AC21 and oil passage TA25 are opened, oil passage BC22 and oil passage TB26 are opened, and because the left hydraulic pressure and the right hydraulic pressure are equal, the shuttle valve spool 31 does not operate, and at this time, the oil passage a14 and the oil passage B15 of the system are in a locked state. If the oil way A14 or the oil way B15 has overload, the oil way A14 or the oil way B15 passes through built-in overflow valves on two sides, and overload hydraulic oil enters an oil tank through an oil passage TA25 or an oil passage TB26 port. Meanwhile, the hydraulic lock corresponding to the oil path B15 or the oil path A14 can reversely open the check valve in the corresponding hydraulic lock under the action of the oil return resistance Pt, and oil supplement is realized through the oil passage TB26 → the oil passage BC22 → the oil path B15 or the oil passage TA25 → the oil passage AC21 → the oil path A14. As shown in fig. 3, namely, the oil path a14 is overloaded, the internal overload relief valve on the side of the oil path a14 is opened, and the overload hydraulic oil enters the oil tank through the oil path TA 25; at the same time, the check valve on the side of oil passage B15 opens, and the oil pressure is replenished through oil passage TB26 → oil passage BC22 → oil passage B15. The arrows in fig. 3 indicate the overflow and oil replenishment paths.
When the main valve stem 13 moves rightward, the oil passage AP23 → the oil passage AC21 is opened, and the oil pressure of the oil inlet P12 passes through the oil passage AP23 → the main valve hole → the oil passage AC21 → the check valve → the oil passage a14 to supply oil to the oil passage a 14; meanwhile, since the oil pressure on the side of the oil passage AC21 is larger than that on the side of the oil passage BC22, the shuttle spool 31 moves rightward, the right check valve opens, and the oil pressure on the oil passage B15 returns to the tank through the oil passage B15 → the check valve → the oil passage BC22 → the main valve hole → the port of the oil passage TB 26.
When the main valve rod 13 moves leftward, the oil passage BP24 → the oil passage BC22 is opened, and the oil pressure of the oil inlet P12 passes through the oil passage BP24 → the main valve hole → the oil passage BC22 → the check valve → the oil passage B15 to supply oil to the oil passage B15; meanwhile, because the oil pressure on the side of the oil passage BC22 is larger than that on the side of the oil passage AC21, the shuttle spool 31 moves to the left, the left check valve opens, and the oil pressure on the oil passage a14 returns to the tank through the oil passage a14 → the check valve → the oil passage AC21 → the main valve hole → the oil passage TA 25.
The innovation point of the technical scheme is as follows:
1. the hydraulic lock has the advantages that the hydraulic lock is structurally designed, the hydraulic lock and the oil supplementing valve are coaxially arranged, the outer end of the hydraulic lock is the overload valve, and the insertion end of the cartridge valve is the hydraulic lock with the oil supplementing function.
2.
