<P>PROBLEM TO BE SOLVED: To provide a draining device capable of attaining cost reduction while appropriately discharging condensate from a gas passage even when pressure of gas passing through the gas passage is low. <P>SOLUTION: This device comprises a gas leakage preventing part Vt in which a drain flowing-down passage 42 flowing down and guiding the condensate into a drain tank 41 is connected in the middle of the gas passage R, a valve part V is provided at the drain flowing-down passage 42, and the valve part V is brought into contact with a gas leakage preventing valve seat 45 by pressure in the gas passage R to prevent leakage of the gas, and a gas leakage preventing float body 46 is provided which floats from the gas leakage preventing valve seat 45 by floating force of the condensed water from the gas passage R and allows flowing-down of the condensed water; and a reverse flow preventing part Vr having a reverse flow preventing float object 48 which is brought into contact with a reverse flow preventing valve seat 47 by floating force of the condensed water from the drain tank 41 for preventing reverse flow of the condensed water. <P>COPYRIGHT: (C)2004,JPO |
