Abstract
The utility model discloses a multi-pipe loss-preventing plastic diesel filter which comprises a shell, a cover plate and a filter element. The multi-pipe loss-preventing plastic diesel filter is characterized in that the shell and the cover plate are made of degradable plastic materials, the filter paper of the filter element is made oil-water separation paper, four oil pipes which include an oil inlet pipe, an oil outlet pipe, an oil return and inlet pipe and an oil return and outlet pipe are arranged on the cover plate. The oil inlet pipe is communicated with the shell inner cavity on the periphery of the filter element. The oil outlet pipe is communicated with the inside of the filter element. An oil return control valve is disposed between the oil return inlet pipe and the oil return outlet pipe. A water accumulation cavity and a draining hole are formed at the bottom of the shell inner cavity. A water level sensor is mounted in the water accumulation cavity. The draining hole is plugged by a draining screw which is connected with the cover plate in a threaded manner. When the draining screw is rotated, the draining screw is lifted to open the draining hole for draining. The multi-pipe loss-preventing plastic diesel filter is environmental friendly, impurities and water in fuel can be filtered effectively, and oil return, oil return control and notification draining functions are provided.
Description
Technical field
The utility model relates to a kind of improvement invention of diesel-oil filter.
Background technique
The effect of diesel-oil filter is the objectionable impurities in filtering diesel systems, and the normal work of protection diesel engine, reduces wear, and avoids stopping up, and improves the diesel engine life-span.Current diesel-oil filter, has the following disadvantages, and 1. housing adopts metallic material, and pickling processes, not environmental protection will be electroplated in the surface of metallic material; 2. the effective moisture in filter fuel of filter core; 3. do not possess oil return and oil return and control function; 4. do not possess notice drain function.
Summary of the invention
In view of the deficiency that background technique exists, the utility model provides a kind of environmental protection feature that has, and effective impurity and the moisture in filter fuel possesses the multitube loss prevention plastics diesel-oil filter that drain function was controlled and notified in oil return, oil return.
The utility model takes following technological scheme to complete:
Multitube loss prevention plastics diesel-oil filter, comprises housing, cover plate and filter core, and cover plate covers the open top of housing, and filter core is located in housing, it is characterized in that: housing, cover plate adopt degradation plastic material, and the filter paper material of filter core is oil-water separation paper.Cover plate is provided with four oil pipes, be respectively oil inlet pipe, oil outlet tube, oil return oil inlet pipe and oil return oil outlet tube, oil inlet pipe communicates with the housing inner chamber of filter core periphery, oil outlet tube communicates with filter core inside, between oil return oil inlet pipe and oil return oil outlet tube, be provided with oil return control valve, when oil return control valve is closed, oil return oil inlet pipe communicates with the housing inner chamber of filter core periphery, when oil return control valve is opened, oil return oil inlet pipe directly communicates with oil return oil outlet tube.The bottom of housing inner chamber is provided with ponding chamber and dewatering orifice, and water level sensor is installed in ponding chamber, and dewatering orifice is blocked by the screw rod that discharges water, and discharge water screw rod and cover plate screw thread spin, and when discharging water bolt rotary, the screw rod that discharges water rises and opens dewatering orifice and discharges water.
Adopt after technique scheme, the utility model can be realized following beneficial effect: 1. housing, cover plate adopt degradation plastic material, and degradable after replacement of products, has environmental protection feature; 2. the filter paper material of filter core is oil-water separation paper, effectively impurity and the moisture in filter fuel; 3. possess oil return and oil return and control function, when the fuel oil at flow direction engine place is superfluous, can flow into filter cleaner by oil return oil inlet pipe secondary filters, when the pressure of filter cleaner inside or excess Temperature, oil return control valve is opened, make engine oil return not flow into filter cleaner, and directly through oil return oil outlet tube, flow in fuel tank coolingly, prevent from that filter cleaner internal pressure or temperature from raising to damage filter cleaner; 4. possess notice drain function, after the long-time use of product, the bottom of housing inner chamber produces a large amount of ponding, and when reaching the sensed position of water level sensor, circuit is connected and pointed out the operation that discharges water, and the screw rod that now rotatably discharges water is opened dewatering orifice and discharged water.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural drawing of the present utility model,
Fig. 2 is the plan view of Fig. 1,
Fig. 3 is the A-A view of Fig. 2.
Embodiment
As shown in the figure, multitube loss prevention plastics diesel-oil filter of the present utility model, comprise housing 9, cover plate 7 and filter core 6, cover plate 7 covers the open top of housing 9, filter core 6 is located in housing 9, housing 9, cover plate 7 adopts degradation plastic material, filter paper 13 materials of filter core are oil-water separation paper, cover plate 7 is provided with four oil pipes, be respectively oil inlet pipe 1, oil outlet tube 4, oil return oil inlet pipe 3 and oil return oil outlet tube 2, oil inlet pipe 1 communicates with the housing inner chamber 10 of filter core periphery, oil outlet tube 4 communicates with filter core inside 5, between oil return oil inlet pipe 3 and oil return oil outlet tube 2, be provided with oil return control valve 14, opening or closing by pressure or the temperature of filter cleaner inside of oil return control valve 14 controlled, when oil return control valve 14 is closed, oil return oil inlet pipe 3 communicates with the housing inner chamber 10 of filter core periphery, when oil return control valve 14 is opened, oil return oil inlet pipe 3 directly communicates with oil return oil outlet tube 2, the bottom of housing inner chamber 10 is provided with 15He dewatering orifice, ponding chamber 11, the interior installation water level sensor in ponding chamber 15 (not shown in FIG.), dewatering orifice 11 is blocked by the screw rod 8 that discharges water, the screw rod 8 that discharges water spins with cover plate 7 screw threads, when rotation discharges water screw rod 8, the screw rod 8 that discharges water rises and opens dewatering orifice 11 and discharges water, need in addition to mention a bit: the mounting hole 12 that water level sensor is installed is blind hole before water level sensor is installed, when water level sensor is installed, with product, subsidiary punch is installed after blind hole is punched again again, guarantee the cleaning inside degree of filter cleaner before entrucking not.
The utility model is work like this: while normally working, fuel oil flows into the housing inner chamber 10 of filter core periphery from oil inlet pipe 1 oil-feed, after filtering, filter core 6 enters filter core inside 5, then from oil outlet tube 4, flow out and enter motor, when the fuel oil of flow direction engine is superfluous, unnecessary fuel oil filters by 3 two inflow filter cleaners of oil return oil inlet pipe, during if there is the pressure of filter cleaner inside or excess Temperature, oil return control valve 14 is opened (state described in Fig. 3), make engine oil return not flow into filter cleaner, and directly through oil return oil outlet tube 2, flow in fuel tank cooling, prevent that filter cleaner internal pressure or temperature rising from damaging filter cleaner, and after the long-time use of product, the bottom of housing inner chamber 10 can produce a large amount of ponding, and when reaching the sensed position of water level sensor, circuit is connected and pointed out the operation that discharges water, the screw rod 8 that now rotatably discharges water is opened dewatering orifice 11 and is discharged water, and guarantees the spatter property of fuel oil and extends filter element life.
