<p>PROBLEM TO BE SOLVED: To provide a switching valve constituting a complex valve which reduces a manufacturing cost by reducing the number of processing points of a valve main body, is dispensed with piping work even if a plurality of the complex valves are arranged, and can be installed even in a narrow space.SOLUTION: A valve main body 2 of a switching valve 1 comprises: a flow-in port 2e and a send-out port 2d of a first fluid; a flow-in port 2g and a send-out port 2f of a second fluid; a discharge port for accommodating a valve body 3a and discharging the first fluid or the second fluid; and a valve chamber 2a having a passage into which the first fluid or the second fluid flows. A part of the flow-in port and the send-out port of the first fluid and a part of the flow-in port and the send-out port of the second fluid are made to directly communicate with each other so as to overlap on the valve chamber, the fluid from the passage is made to flow to the send-out port of the first fluid or the send-out port of the second fluid by the rotation of the valve body around an axial line, and the fluid flowing in the flow-in port of the first fluid or the flow-in port of the second fluid is made to flow to the discharge port.</p> |
