DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] In the drawings, the same reference numerals all refer to the same components.

[0021] like Figure 1As shown, a remote intelligent controlled hydraulic reversing valve comprises a valve body 1 and a hydraulic controller 2, characterized in that it also comprises a wired controller 14 and a wireless controller 13, the hydraulic controller 2 is connected to a command receiver 3, the command receiver 3 can be connected to the wired controller 14 and the wireless controller 13 for signal respectively, the antenna 4 of the command receiver 3 is a 5G antenna, installed on the side of the command receiver 3, the command receiver 3 is externally connected to the wired controller 14, the command receiver 3 is bridged with the wired controller 14 through a signal line 5, the signal line 5 is a pure copper twisted pair shielded line, the antenna (4) is connected to the wireless controller 13 through a wireless signal, the shell of the wireless controller 13 is made of glass fiber nylon, and anti-collision angles 6 are arranged around the shell.

[0022] The hydraulic controller 22 is driven by a motor, and is connected to the command receiver 3 on the side through a signal line. The command receiver 3 is provided with an interface and an antenna. The interface is connected to the signal line 5 to receive the command of the wired controller 14, and the antenna receives the wireless signal of the wireless controller 13. According to the wireless signal received by the command receiver 3, the hydraulic controller 2 is controlled to push out the hydraulic oil and push the valve core 15 to move, and a return device 7 is set on the other side of the valve core 15. The return device 7 includes a spring 71 and a central telescopic column 72. The central telescopic column 72 is set between the valve body and the valve core 15, and the spring 71 is sleeved on the central telescopic column 72. When the hydraulic controller 22 retracts the hydraulic oil, the return device 7 forces the valve core 15 to return to the initial position.

[0023] Furthermore, the antenna 4 of the command receiver 3 is a 5G antenna, which is installed on the side of the command receiver 3.

[0024] Furthermore, the number of the antennas 4 is 1 to 4.
