Preferably, the pressurizing means may be configured as a control valve that opens and closes to control supply and shut-off of fluid.

Specifically, in order to pressurize the fluid to a specific pressure preset by the administrator, the control valve is opened to pressurize the fluid to the specific pressure, and when the pressurization is completed, the control valve may be closed to block the flow of the fluid.

The safety valve 20 is mounted to be detachably attached to a pipe provided in the pressure vessel 10, and may open and close when the pressure inside the pressure vessel 10 increases, thereby adjusting the pressure inside the pressure vessel 10.

In detail, the safety valve 20 is provided to be detachably attached to one side of the valve holder provided in the pipe, so that it is easy to replace the safety valve 20 requiring a performance test.

As described above, the fluid ejected due to the operation of the safety valve 20 is stored in the discharge storage tank 30 to be described later.

That is, the discharge storage tank 30 is a configuration for accumulating and storing the fluid ejected from the safety valve 20, and prevents damage to the inner wall due to the rapid ejection of the fluid, which is high pressure steam, and prevents the outflow of fluid. In order to ensure safety, it is preferable to provide a reinforcing material having a predetermined thickness on the inner wall.
