<P>PROBLEM TO BE SOLVED: To solve the following problems of a drain valve including an equalizing pipe for preventing air lock: connection positions are needed in both the body of the drain valve and a counterpart, and the pipe occupies space. <P>SOLUTION: To discharge drain water, drain water discharge pipes 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 130 are used for connection between the bottom of a drain water generating device 10 for generating drain water by condensing compressed air and a drain trap 110 for discharging drain water when a fixed amount of drain water is stored. In addition, all the diameters of the drain water discharge pipes 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 130 are set to be equal to or larger than 13.4 mm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
