Claims

[Scope of utility model registration request]

A cylindrical valve housing body having a pair of holes formed in two, three, or four directions for the switching port on its circumferential surface, and in which these pairs of holes are formed in multiple stages vertically; A flow path pipe fitted into each hole so that the inner end opening forms a valve seat of the ball valve, and a ball valve inserted into each stage within the valve housing body so as to be supported by each valve seat. , a connecting drive shaft that connects each ball valve and a main drive that rotationally drives the ball valve located on the end side of the valve housing body in order to connect adjacent ball valves and drive them to rotate together. A multiple type switching valve device characterized by comprising a shaft.
