<p>PURPOSE:To efficiently absorb a leaked liquid. CONSTITUTION:A coned disc spring 19 is received in the spring receiver 18 of a plug 11 and a suction hole 22b is provided to the fitting member 22 of a socket 12. The socket 12 is moved by an air cylinder so as to relatively approach a plug 15 and the fitting part 22 is fitted in an insertion pipe 16 to connect both of the plug and the socket 12. At this time, a movable pipe 23 is pushed by the insertion pipe 16 to recede and a valve body 24 pushes a valve body 17. Therefore, liquid passages 23a, 16a open to communicate with each other. When the air cylinder is set to a neutral state, the socket 12 is slightly separated from the plug 11 by the action of the coned disc spring 19 and the liquid passages 23a, 16a are closed but the fitting member 22 is still fitted in the insertion pipe 11. In this state, a suction device is operated to suck air from the suction hole 22b. The sucked air vigorously flows through the narrow gap between the fitting member 22 and the insertion pipe 16 to remove a leaked liquid.</p> |
