The hydraulic one-way valve includes a valve body, an upper end cover arranged at the upper end of the valve body, and a lower end cover arranged at the lower end of the valve body. A piston chamber and a valve chamber are arranged in the valve body. A control piston is arranged in the piston chamber to divide the piston chamber into two parts, an upper part and an lower part. A valve seat is arranged in the valve chamber. Based on the existing ordinary hydraulic one-way valve, an electromagnetic valve is added to the end cover of the control piston end of the hydraulic one-way valve. The electromagnetic valve oil circuit is divided into the bottom end of the piston of the hydraulic one-way valve and both sides of the oil inlet and outlet. The electromagnetic valve is used to arbitrarily control the opening and closing of the hydraulic one-way valve; since the sealing property of the electromagnetic hydraulic one-way valve belongs to a leak-free cone valve seal, it has a good seal and realizes reliable pressure maintenance of a single-acting oil cylinder. According to the above, although the device can be well applied, it is usually not convenient for dual-channel medium transportation, which makes it difficult for the electromagnetic hydraulic lock to achieve the intended transportation effect, which often troubles users.
