Example Embodiment
[0012] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
[0013] As shown in the figure, a hydraulic multi-way reversing valve is composed of left and right drive valves. The drive valve includes a drive valve body 1 and a valve core 2. The drive valve body is provided with an overload protection valve 3 and an overload protection valve. Connected with the oil inlet and outlet 4 of the valve body, the overload protection valve includes the main valve body 5, the auxiliary valve body 6, the valve needle 7 and the one-way valve core 8. The one-way valve core plays the role of replenishing oil, effectively solving the problem of Insufficient oil supply for a single action causes the problem of negative pressure at the oil supply port to prevent air suction. The rear end of the main valve body is screwed with an auxiliary valve body, the cavity of the auxiliary valve body is p...
