Abstract
The utility model discloses a fuel filter which comprises a case, a first filtering screen, a second filtering screen, a fuel inlet, a fuel outlet and an airtight cover. The first filtering screen and the second filtering screen are fixed at the lower end inside the case. The first filtering screen is arranged inside the second filtering screen. The fuel inlet is arranged at the lower end of the case and extends into the first filtering screen. The airtight cover is arranged at the upper end of the case. The fuel outlet is arranged at the upper end of the airtight cover. Threads are respectively arranged on the airtight cover and the upper end of the interior of the case. The airtight cover and the case are connected and fixed in a threaded mode. A sealing ring is arranged between the airtight cover and the case. By means of the first filtering screen and the second filtering screen which are arranged inside the case, fuel can be filtered two times, small impurities in the fuel can be filtered off, and therefore the fuel with low impurity content can be obtained, fuel quality is improved, and the fuel filter is simple in structure, and convenient to install and dismantle and clean.
Description
Technical field
The utility model relates to a kind of fuel filter.
Background technique
Along with growth in the living standard, the Motor Vehicle such as automobile constantly increase, and Motor Vehicle all be unable to do without fuel oil, fuel oil has passed through precipitation and has filtered before adding diesel oil tank, common people think that this cleans, but in refueling process, factor still can make contaminated by diesel oil because fueling vehicle, oiling circumstance, reservoir port be unclean etc., and in the diesel engine process, due to the dust that suspends in the impurity that deposits in oil-fired system, air, also can make contaminated by diesel oil, so one of the accessory that is absolutely necessary of the diesel-oil filter on car.
