Abstract

PURPOSE: To effect a rapid draining of a heat exchanger even when the water head is small, by using a water trap having an air valve at the uppermost portion of a drain pipe and a drain valve at the lowermost portion thereof, which drain pipe, connected to a discharge port of the drain valve, has an inner diameter equal to or smaller than the diameter of the discharge port.
CONSTITUTION: An air valve 4 is provided at the uppermost portion of a pipe 3, and a drain valve 5 at the lowermost portion thereof. Flexible drain hoses 6, 7 are connected to the valves 4, 5, respectively. The inner diameter of the drain hose 7 is equal to or smaller than the diameter of a discharge port 8 of the drain valve 5. When the drain valve 5 is opened, the drain hose 7 is filled with water even when the water head is small. Therefore, the water in the pipe 3 is sucked by a force corresponding to the weight of the water dropping in the hose 7 so that the draining operation can be carried out properly at a high speed.
