In addition, the number of the plurality of seat rings 32 shown in fig. 4 corresponds to the number of the plurality of flow passages 3, that is, the number of the plurality of seat rings 32 is three, each seat ring 32 includes two

opposite end portions

321, 322, one of the two end portions 321, 322 (the end portion 322) is provided with a valve seat 33, and the other of the two end portions 321, 322 (the end portion 321) is provided with a plurality of screw holes 320, for example, three, four, five screw holes 320 are provided at equal angles.

In the above structure, as shown in fig. 4, the plurality of seat rings 32 are respectively disposed in the plurality of passages 22 of the branch valve body 2, and the seats 33 of the plurality of seat rings 32 are respectively adjacent to the branch valve body 2, the plurality of flow passages 3 are respectively connected and assembled to the plurality of passages 22 of the branch valve body 2 by the connecting portions 31, and are respectively adjacent to the end portions 321 of the plurality of seat rings 32 having the plurality of screw holes 320, in the present embodiment, the plurality of flow passages 3 are respectively connected and assembled to the plurality of passages 22 by the connecting portions 31 by the plurality of bolts 34, and a leakage preventing member 23 is provided at the connecting portion to prevent fluid leakage.
