<p><P>PROBLEM TO BE SOLVED: To provide a space saving joint with easy change-over operation between a normal usage state and an inspection state. <P>SOLUTION: A joint body 2 is provided with a first connection part 21 connected to a heat source machine having a heat medium supplying function, a second connection part 22 connected to a terminal apparatus supplying a heat medium from the heat source machine, and a third connection part 23 connected to a fluid supplying part for inspection supplying a fluid for inspection to the terminal apparatus. The joint 1 is provided with a change-over means 3 capable of freely carrying out a change-over between the normal usage state communicating the heat medium between the first connection part 21 and the second connection part 22, and the inspection state communicating the fluid for inspection from the third connection part 23 to the third connection part 22 while cutting off the first connection part 21 from the second connection part 22. The change-over means 3 is provided with a change-over operation part 34 freely turning with respect to the joint body 2, and a valve element 35 carrying out the change-over between the normal usage state and the inspection state by being reciprocated with respect to the change-over operation part by turning operation of the change-over operation part 34, and closing/opening the first connection part 21. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
