High-low pressure double-pump confluence multi-way valve

The utility model discloses a high-low pressure double-pump confluence multi-way valve which comprises a low-pressure side oil inlet body, a low-pressure side reversing valve plate, a confluence gap bridge valve plate, a high-pressure side reversing valve plate and a high-pressure side oil inlet body, and the low-pressure side oil inlet body comprises a valve body, a differential pressure guide rod, a one-way valve, an unloading valve and a safety valve. The valve body is provided with a low-pressure oil inlet channel connected with a low-pressure pump, a confluence oil channel section, a main control oil channel section and an oil return channel, and when the oil pressure of the confluence oil channel section exceeds the protection pressure of the safety valve, a valve element of the safety valve is opened, and meanwhile the differential pressure guide rod moves to the position abutting against the valve element. And when the pressure of the confluence oil duct subsection is reduced to the set specific value
