It can realize automatic water-replenishing operation, has a simple and efficient structure, ensures the water-replenishing effect, and is suitable for long-term uninterrupted testing.

[0027] like Figure 1As shown, the automatic water replenishment salt spray test device includes a brine tank 1, a brine supply container 2, a connecting hose 3, a lifting pipe 4 and a one-way check valve 5. The brine supply container 2 is arranged above the brine tank 1, the first end of the connecting hose 3 is connected to the brine supply container 2, the second end of the connecting hose 3 is connected to the inlet end of the lifting pipe 4, the one-way check valve 5 is installed at the outlet end of the lifting pipe 4, the lifting pipe 4 is penetrated on the brine tank 1 and is used for lifting and adjusting the depth of penetration into the brine tank 1, the one-way check valve 5 is used to open the outlet end of the lifting pipe 4 when the liquid level height in the brine tank 1 is lower than the setting height of the one-way check valve 5, and the one-way check valve 5 is also used to close the outlet end of the lifting pipe 4 when the liquid level height in the brine tank 1 reaches the setting height of the one-way check valve 5.

[0028] The automatic water replenishment salt spray test device realizes the opening or disconnection of the automatic water replenishment channel through the one-way check valve 5. When the liquid level height in the brine tank 1 is lower than the setting height of the one-way check valve 5, the brine supply container 2 can be automatically opened to replenish brine for the brine tank 1. When the liquid level height in the brine tank 1 reaches the setting height of the one-way check valve 5, the brine supply container 2 can be automatically disconnected to avoid excessive brine in the brine tank 1, thereby realizing long-term automatic quantitative water replenishment operation, and by adjusting the depth of the lifting hard pipe 4 penetrating into the interior of the brine tank 1, the setting height of the one-way check valve 5 can be accurately adjusted, thereby meeting different liquid level height requirements and being suitable for different test parameter requirements.
