[0028] Further, the mounting plate 303 is provided with a mounting hole 3031. The mounting hole 3031 is fixed to the valve block 1 by bolts, so that the mounting plate 303 can be easily disassembled and maintained.

[0029] Further, the oil inlet pipe 201 is fixed to the valve block 1, and the oil inlet pipe 201 is locked between the first ball valve 2 by a nut, so that the first ball valve 2 is fixed by the oil inlet pipe 201.
