PURPOSE: An application method and device of a valve is provided to save water, to cut down the cost of equipment, and to prevent diffusion of a bad smell in a sink. CONSTITUTION: A drainage passage(24) and a water passage(25) are formed to a water supply pipe(26) of the side of a body(1). A flow control bolt(23) is combined to the upper end of the water passage. A pipe(9) is connected at the bottom of a water supply pipe(28). A packing(15 ) is mounted on an annular projection(16) of the lower end of a piston(11), and a hilt(10) of a valve(8) is put on the packing and then a spring(14) is combined, with a fixing ring(12). The piston, having a U-packing(13) fitted into an uneven groove(36) of the upper end of the piston, is installed within the fresh valve body having a plane(39). A circular projection(33) having a drainage hole(38) and a drainage pipe(32) forming an outer brim(34) are combined to an internal thread of the lower end of the body. An O-ring(35) is fitted into the outer brim, and a packing(18) is put on the circular projection. A rotating shaft(31) of push rods(20,22) having O-rings(19) is mounted to holes(2,5) of a drainage pipe, and a handle(21) is fixed to the end of the rotating shaft. A bolt of a drainage tank is fitted into an external thread of a water tank of a sink, and a nut having a hole is coupled. The lower end of a vertical drainage pipe is connected to the upper end of a drainage pipe, and a horizontal drainage pipe of the vertical drainage pipe is fitted into an overflow drainage hole of the water tank.
