As described above, the proposed bracket structure (eg, the structure shown in FIG. 3) in which the first service valves 31 and 32 and the second service valves 33 and 34 have a step 730 and are arranged in a zigzag pattern ( The second effective distance ℓ2 in (see (a) of FIG. 8) is a plane where the service valves (eg, the first service valves 31 and 32 and the second service valves 33 and 34) do not have a step difference. It may be relatively longer than the first effective distance ℓ1 in a general bracket structure (see (a) of FIG. 7) arranged in a line on the vertical axis of 750. The general bracket structure may be, for example, a structure in which a plurality of service valves are arranged in a straight line along a vertical axis on an upper surface 750 of one plate.

Therefore, the spanner operating range (e.g., effective working radius) in the proposed bracket structure in which service valves are arranged zigzag on two plates having a step 730 is a general bracket in which service valves are arranged in a line on a vertical axis without a step difference. It can be relatively wide compared to the spanner operating range (eg effective working radius) in the structure. The reason is that, in the proposed bracket structure, the second upper surface 490 of the second plate 22 provided to be positioned relatively lower than the first upper surface 410 of the first service valves 31 and 31 is a spanner ( This is because the pipe fastening work can be continued until the rotation of 60) acts as an interference. The fact that the operating range of the spanner is wide may be understood as having a similar meaning to, for example, that the rotation angle of the spanner 60 is large during pipe fastening work.

As an example, the first effective distance ℓ1 is a general bracket structure in which service valves are arranged in a row on a vertical axis (eg, the structure shown in (a) of FIG. 7), the service valve 32 is disposed Position (a1) where the spanner 60 rotates upward during the pipe fastening work for the service valve 32 from the position (a1) where the spanner 60 touches the upper surface of the plate without a step difference (eg, the position where interference occurs 710 and 720 in FIG. 7 )) can be defined as the straight-line distance to The first effective distance ℓ1 is, for example, the fixing nut (eg, center) and the spanner 60, which are fastening members 321 provided in the service valve 32 mounted on the first plate 21, It may be the distance to the position (a1) of the upper surface, which is a high floor provided on the plate that comes into contact during rotation with .

For example, when the spanner 60 is operated vertically for work, the rotatable angle of the spanner 60 may be up and down. This is due to interference 710, 720 due to the service valve adjacent to the fastening member 321 and/or the bottom of the bracket (eg, bracket 20 in FIG. 1).

According to one embodiment, in the case of a structure in which the service valves in the bracket 20 are not arranged in a line on the vertical axis but arranged in a zigzag pattern (eg, the structure shown in FIG. 8(a)), any service valve 32 ) When tightening or loosely adjusting the fixing nut, which is the fastening member 321 provided in the spanner 60, the rotatable angle of the spanner 60 may increase to approximately 125 degrees ((FIG. 8) see b)). For example, when the spanner 60 is operated vertically for work, the rotatable angle of the spanner 60 may be up and down. This is due to interference caused by the service valve adjacent to the fastening member 321 and/or the bottom of the second plate 22 constituting the bracket 20 (eg, the upper surface 490 of the second plate 22).
