The beneficial effects of adopting the further technical scheme are as follows: when the diesel engine continuously works, the water filtered by the diesel engine reaches the first preset water discharge level of the first filter bowl, and when the buoyancy of the one-way valve reaches the preset buoyancy of the one-way valve opening, the one-way valve is opened, the water stored by the first filter bowl is discharged to the second filter bowl, when the water level of the first filter bowl is reduced, the buoyancy of the one-way valve is reduced when the diesel engine is full of the first filter bowl, the one-way valve is closed, and the fuel in the filter is prevented from leaking to the second filter bowl. The buoyancy check valve ensures that water from the second filter bowl is no longer flowing back into the first filter bowl.
The alarm device can be a buzzer, an alarm lamp, an alarm display screen and the like.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
