It should be noted that part or all of the shape of each configuration constituting the present invention, such as the body 100, may be modified and implemented according to the application method of the valve structure 10 .

An inlet 101 through which a fluid such as water is introduced and an outlet 102 through which the fluid is discharged are formed in the body 100 . A filter 700 is disposed at the inlet 101 side to filter out foreign substances from the supplied fluid. The filter 700 is accommodated by the connection member 800 detachably fastened to the inlet 101 side of the body 100 and may be connected to a water pipe to which a fluid is supplied.

The fluid introduced into the inlet 101 may flow along the inlet flow path 103 formed inside the body 100 into the hollow blocking hole 105 of a cylindrical shape with one side open. The fluid introduced into the blocking hole 105 may flow through the discharge passage 104 and be discharged to the discharge port 102 . The inflow passage 103 may be connected to a lower portion of the blocking hole 105 , and the discharge passage 104 may be connected to an upper portion of the blocking hole 105 . A separate nozzle tip (not shown) for increasing the hydraulic pressure of the discharged fluid is detachably fastened to the outside of the outlet 102 , so that the fluid discharged through the outlet 102 can be discharged at high pressure.

The blocking hole 105 is formed so as to pass through the flow path and the outside in which the inflow flow path 103 and the discharge flow path 104 are connected. One end of the elastic member 500 may be fixed to the lower inner wall of the blocking hole 105 . The inner end of the blocking member 400 may be seated on the other end of the elastic member 500 to be elastically supported to the outside.

The blocking member 400 may be disposed to pass through the flow path forming member 200 disposed inside the blocking hole 105 and the guide member 300 coupled to the outer opening of the blocking hole 105 , respectively.

The flow path forming member 200 may be coupled in the blocking hole 105 such that the outer surface thereof is in close contact with the inner surface of the blocking hole 105 . The flow path forming member 200 may be formed to separate the upper part and the lower part of the blocking hole 105 . The fluid does not pass between the outer surface of the flow path forming member 200 and the inner surface of the blocking hole 105 , but from the inflow path 103 through the fluid through hole 210 formed in the flow path forming member 200 .
