<p><P>PROBLEM TO BE SOLVED: To provide a three-way cock which supplies liquid chemical smoothly without generating stagnation of the liquid chemical within a second introduction pipe and a valve body. <P>SOLUTION: The three-way cock includes a main channel 9 penetrating through the valve body 3 and a loop groove 10 formed on the side of the valve body 3 and extending in the circumferential direction from one end to the other end of the main flow channel. The loop groove 10 includes a first loop groove 11 extending from the one end of the main channel 9 to the middle of the loop groove 10 and a second loop groove 12 extending from the middle to the other end of the main channel 9. The first loop groove 11 becomes gradually narrower and deeper from the one end side of the main channel 9 toward the middle. The second loop groove 12 has a constant width and depth that are wider and shallower than the end of the first loop channel. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
