The first normally closed valve S01 is connected to the first branch 21 and exposed outside the mounting plate 1, and the solenoid valve D01 is connected to the second branch 22 and exposed outside the mounting plate 1. The second end of the first branch 21 is also connected to the oil pressure device 3.

[0021] In this way, during automatic air replenishment, the solenoid valve D01 is opened, gas enters from the first end of the second branch 22 of the pipeline structure 2, passes through the solenoid valve D01 and then enters the second end of the first branch 21 from the second end of the second branch 22, and then enters the oil pressure device 3 to provide gas for the oil pressure device 3;

[0022] When the solenoid valve D01 fails to achieve automatic air replenishment, the solenoid valve D01 is in a closed state at this time. The first normally closed valve S01 can be manually opened, and the gas enters from the first end of the second branch 22 of the pipeline structure 2.

The gas passes through the solenoid valve D01 and then enters the second end of the first branch 21 from the second end of the second branch 22, and then enters the oil pressure device 3 to provide gas for the oil pressure device 3;

[0028] When the solenoid valve D01 fails to achieve automatic air replenishment, the solenoid valve D01 is in a closed state at this time. The first normally closed valve S01 can be manually opened, and the gas enters from the first end of the second branch 22 of the pipeline structure 2. The gas flows through the first normally closed valve S01 to the second end of the first branch 21, and then enters the oil pressure device 3 to provide gas for the oil pressure device 3, realizing two functions of automatic air replenishment and manual air replenishment.
