[0034] In this embodiment, the seat plate 11 is fixed to the outer wall of the cabin 1 by welding.

[0035] In this embodiment, the valve body of the isolation valve 2 is in cylindrical structure, one side of which forms a threaded connection section, and the threaded connection section is in sealed connection with the flange 21.

[0036] In this embodiment, the flange 21 and the seat plate 11 are connected by a plurality of bolts.

[0037] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 1 and 2 , a drain port is formed in the lower end of the valve body, and the drain port is connected with a drain test plug 21.
