The invention discloses a duplex type
hydraulic control one-way valve, which comprises a valve body and a main valve core and is characterized in that a valve cavity is arranged in the valve body, the main valve core is arranged in the valve cavity, a spring connected with the top of the valve body is arranged inside the main valve core, an axial
small hole is formed in the lower end of the main valve core, a radial hole communicated with the axial
small hole is formed in the outer circle of the main valve core, the axial
small hole is sealed through an unloading valve core push rod, an unloading valve core is arranged at the upper end of the unloading valve core push rod, a control opening is formed in the bottom of the valve body, a
piston is arranged in the valve cavity arranged at the upper end of the control opening, a push rod is connected with the upper end of the
piston, and the push rod can push the unloading valve core push rod to upwards move. The duplex type
hydraulic control one-way valve solves the problems that the one-way valve can only realize the one-way flowing, the stable reverse flowing cannot be realized, the use function is single, in addition, the damage can easily occur, and the service life is short. The provided duplex type
hydraulic control one-way valve has the advantages that the structure is simple, the use is convenient, the two-way flowing can be fast and stably realized, in addition, the damage cannot easily occur, and the service life is long.
