Abstract
The invention discloses an exhaust type fuel filter applied to an automobile, which comprises a shell (6), a filter element assembly (4) and a screw sealing plate (2), wherein a water discharging assembly is arranged at the bottom of the shell, an annular gasket (3) is arranged between the screw sealing plate and an upper end cover of the filter element assembly, and an exhaust channel (13) is arranged inside the annular gasket. A water level sensor is arranged on the bottom of the shell and at the side of the water discharging component. The invention leads the gathered gas in the filter to pass through the oil outlet and to be discharged from the oil inlet through the exhaust channel of the annular gasket. And then reduce the air resistance of filter element group spare's upper end cover department for the fuel liquid level can rise to the design height, improves filter element group spare's utilization ratio, has the preferred filter effect, guarantees fuel oil system's normal operating. And can effectively prevent flameout caused by excessive air in the oil path. And the water level sensor is favorable for timely drainage of the drainage component at the bottom of the shell.
Description
Technical Field
The invention relates to a filtering system, in particular to a fuel filter.
Background
At present, the fuel filter is not provided with an exhaust device, so that gas in the filter is gathered and is difficult to discharge smoothly, and the fuel filtering effect is influenced. And the internal air is gathered at the oil outlet of the screw sealing plate, so that the vehicle is easy to flameout due to excessive air in the oil path.
The invention aims to overcome the defects of the prior art and provide an exhaust type fuel filter capable of effectively exhausting air in an internal oil way.
The purpose of the invention is realized by the following technical scheme: the exhaust type fuel filter comprises a shell, a filter element assembly and a screw sealing plate, wherein a water discharging assembly is arranged at the bottom of the shell, an annular gasket is arranged between the screw sealing plate and an upper end cover of the filter element assembly, and an exhaust channel is arranged inside the annular gasket.
A water level sensor is arranged on the bottom of the shell and at the side of the water discharging component.
After the structure of the invention is adopted, the gas gathered in the filter can pass through the exhaust channel of the annular gasket and is discharged from the oil inlet of the filter when passing through the oil outlet of the filter. And then reduce the air resistance of filter element group spare's upper end cover department for the fuel liquid level can rise to the design height, improves filter element group spare's utilization ratio, makes whole filter have the filter effect of preferred, guarantees fuel oil system's normal operating. And can effectively prevent flameout caused by excessive air in the oil path. And the water level sensor is favorable for timely drainage of the drainage component at the bottom of the shell.
Drawings
The invention is described in further detail below with reference to the figures and embodiments.
FIG. 1 is a schematic structural diagram of an air bleeding fuel filter according to the present invention.
Detailed Description
Referring to fig. 1, the exhaust type fuel filter applied to an automobile of the present invention includes a housing 6, a filter element assembly 4 (including an upper end cover 41, a lower end cover 42, filter paper 44, a central tube 43, etc.), and a spiral sealing plate 2, wherein a water discharging assembly 10 is installed at the bottom of the housing 6, an annular gasket 3 (near the top of the central tube 43 of the filter element assembly 4) is installed between the spiral sealing plate 2 and the upper end cover 41 of the filter element assembly 4, an exhaust channel 13 (two ends of which are respectively communicated with an oil outlet 15 and an oil inlet 14 of the filter, and one or two channels can be used, if the number of channels is large, the oil filtering effect can be affected). Fuel enters through an oil inlet 14 (namely, the lateral position of the spiral sealing plate) of the filter, is filtered by the filter element assembly 4 and then is discharged from an oil outlet 15 (namely, the central position of the spiral sealing plate) of the filter, and gas in the filter passes through the oil outlet and then passes through an exhaust channel 13 of the annular gasket 3 to be discharged from the oil inlet (the oil inlet, the filtering, the oil outlet and the exhaust are shown by arrows in fig. 1).
A water level sensor 8 is arranged on the bottom of the shell 6 and at the side of the water discharging component 10 and used for monitoring the height position of the water (after oil-water separation) at the bottom of the shell, which is beneficial to timely water discharging of the water discharging component. A support spring 5 is installed between the bottom of the housing 6 and the lower end cap 42 of the filter element assembly 4.
Claims (2)
1. Exhaust formula fuel filter, including shell (6), filter element group spare (4), the sealed board of spiral shell (2), be equipped with the subassembly that drains (10), its characterized in that in the bottom of this shell (6): an annular gasket (3) is arranged between the screw sealing plate (2) and an upper end cover (41) of the filter element assembly (4), and an exhaust channel (13) is arranged inside the annular gasket (3).
2. The vented fuel filter of claim 1 wherein: a water level sensor (8) is arranged on the bottom of the shell (6) and at the side of the water discharging component (10).
