Abstract

A locking loop using electromagnetic one-way valves with the adjustable cut-off direction comprises an oil pump (210), an oil tank (209) and a hydraulic cylinder (202). The hydraulic cylinder (202) comprises a right oil chamber (207) and a left oil chamber (203). The locking loop further comprises the electromagnetic one-way valves with the adjustable cut-off direction. The electromagnetic one-wayvalves with the adjustable cut-off direction comprises a first electromagnetic one-way valve (200) arranged on the oil circuit between the oil pump (210) and the left oil chamber (203) and a second electromagnetic one-way valve (200') arranged on the oil circuit between the oil tank (209) and the right oil chamber (207). No additional control oil circuit is required for the locking loop using electromagnetic one-way valves with the adjustable cut-off direction, and the structure is simpler.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a locking circuit using an electromagnetic one-way valve with an adjustable cut-off direction. Background technique [0002] The function of the locking circuit is to make the hydraulic cylinder stay in the position, and the circuit will not move the position due to external force after the stay. In the prior art, a hydraulic control check valve is often used to form a locking circuit. Figure 4 A very common locking circuit using a pilot operated check valve is shown. When the reversing valve is in the left position, the pressure oil enters the left oil chamber of the hydraulic cylinder through the hydraulic control check valve 1, and at the same time, the pressure oil also enters the control oil port K of the hydraulic control check valve 2, and the hydraulic control check valve 2 is opened. The oil returned from the right oil chamber of the hydraulic cylinder can flow back to the oil tank t...
