Water level buoyancy automatic drainage fuel filter

Abstract

The invention relates to the field of drainage of fuel filters, in particular to a water level buoyancy automatic drainage fuel filter. The water level buoyancy automatic drainage fuel filter comprises a first cavity, a second cavity, a third cavity and a movable round rod. The second cavity is a cylinder provided with a crescent notch from top to bottom, the crescent notch on the inner side is tightly attached to the side face of the first cavity, and the bottom of the crescent notch and the bottom of the first cavity are on the same horizontal plane. The problems that an engine or peripheral parts are damaged and the environment is destroyed due to manual emission and untimely emission are solved.

Description

technical field [0001] The invention relates to the field of fuel oil filter drainage, in particular to a water level buoyancy automatic drainage fuel filter. Background technique [0002] Because the moisture in the fuel will be deposited under the fuel, the traditional fuel drain filter includes a filter housing, an opening is arranged on the filter housing, a connecting plate is installed at the opening, and an oil outlet is arranged in the middle of the connecting plate. The connecting plate is regularly provided with an oil inlet port around the oil outlet, and the top of the filter housing is provided with a crimp that clamps the connecting plate, and a sealing ring is provided on the crimp to seal the opening on the connecting plate. A filter element is arranged in the housing, the upper part of the filter element is offset against the connecting plate, and a supporting spring is pressed between the lower part and the filter housing for positioning, and the bottom of ...

Problems solved by technology

[0003] This kind of filter needs to be drained manually. If it is not drained in time for a long time, water entering the engine will cause great harm to the engine.

[0004] The separated water may still contain dissolved oil components, so the separated water cannot be discharged directly, otherwise it will affect the environment. The best way is to let the accumulated water discharge by itself and use the heat of the car's own engine and the wind speed during driving to control the accumulation. However, under special conditions, such as poor fuel quality and a lot of water, there is still the possibility of too much water, so that too much water can not be volatilized in time, overflowing from the vent hole may affect the engine or Peripheral parts are damaged
