An open loop pipe flushing apparatus using two different fluids is provided to maximize the washing effect by causing continuous contraction and expansion of gas with the variation of fluid kinetic energy. An open loop pipe flushing apparatus using two different fluids comprises a compressed gas supply valve(01) which allows or blocks the supply of working fluid, a pneumatic unit(02) removing the moisture and contaminant from the compressed gas, a first control valve(24) operated by the pressure of the supplied compressed gas, a second control valve(25) operated by the pressure of the supplied compressed gas or the washing fluid circulating in a pipe, a gas induction pipe(09) inducing the gas into the pipe, a washing fluid backflow prevention valve(16) located between the gas induction pipe and the second control valve, a connection part(07) including a pipe connection flange connected to the pipe, and a third supply pipe(12) delivering the pressure of the washing fluid to the second control valve. |
