As such, when the pump assembly 130 is coupled in a form seated on the support 150, the submersible pump 131 is operated to discharge the stored fluid of the reservoir 200 to the discharge pipe 110 through the pump assembly 130. Done.

As shown in (a) and (b) of FIG. 8, when the submersible pump 131 is operated, the fluid stored in the reservoir 200 moves to the supporter 150 through the extension pipe 133, and the supporter The ball 163 provided in the valve unit 160 is accommodated in the upper portion, more specifically, the receiving groove 161 by hydraulic pressure in a state in which the ball 163 provided in the valve unit 160 blocks the flow path 153 to open the flow path 153.

Thus, the fluid stored in the reservoir 200 is discharged to the outside through the discharge pipe 110 by opening the flow path 153.

On the other hand, when the operation of the submersible pump 131 stops the ball 163 accommodated in the receiving groove 161 is lowered by its own weight to close the flow path 153 is not discharged to the outside of the discharge pipe 110 and discharge pipe ( The fluid remaining in 110 may be prevented from flowing back to the reservoir 200.

In addition, since the valve unit 160 opens the flow path 153 in proportion to the pressure of the discharged fluid, a separate flow control valve is controlled by adjusting the amount of the discharged fluid in the form of controlling the discharge amount of the submersible pump 131. No need to install

Therefore, the submersible pump desorption system 100 provided with the valve according to the embodiment of the present invention does not need to separately install a hydraulic control valve in the discharge pipe 110 because the flow path 153 is automatically opened and closed by the pressure of the fluid. As a result, since the control space 230 may be omitted in the water storage tank 200, the installation cost of the submersible pump 131 may be greatly reduced.

In addition, when the operation of the submersible pump 131 is stopped by the valve unit 160 provided in the support 150, the flow path 153 is automatically shut off, so that the fluid remaining in the discharge pipe 110 flows backward. The generation of a water hammer can be prevented.

In addition, the discharge pipe 110 and the pump combination 130 in the form of seating the pump assembly 130 to the seating portion 170 provided on the support 150 in the upper portion of the reservoir 200 is discharge pipe 110 ), The installation of the submersible pump 131 is easy.

In addition, since the pump assembly 130 and the discharge pipe 110 are coupled at the upper surface of the water reservoir 200, it is possible to easily check the leakage of the fluid of the coupling portion.

In addition, the submersible pump 131 is coupled in an inclined state with respect to the vertical extension tube 133 to prevent the extension tube 133 from being bent by the centrifugal force of the submersible pump 131.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it is recognized that the present invention is easily changed and equivalent by those skilled in the art to which the present invention pertains. Includes all changes and modifications to the scope of the matter.
