Description
Technical field
The present invention relates to a kind of element kit of depth-type filtration material and fuel filter that comprises this element kit of comprising.
Background technology
Diesel fuel filter is vital for the effect of engine, if there is not good diesel fuel filter, the function of engine will be affected and can not realize normal function.Fuel filter is generally by the cleaner seat with spinning and the element kit that is fastened are formed with it.At present the diesel fuel filter filter core by filter paper as filtering material.Yet the cleaner that the domestic diesel engine that reaches state III and the above emission request of state III uses adopts import filter paper usually because of its performance requirement is high, thereby has increased production cost.In addition, because the restriction of material, the dust containing capacity of filter paper also is restricted.Very poor in Chinese market owing to oil product; and because the otherness of the different oil products in region is also very big; caused cleaner short problem in service life; not only reduced the effect of vehicle protection but also increased user's financial burden; for being 60,000 kilometers with the replacing mileage of a cleaner in Europe; and change mileage in China is 1.5 ten thousand kilometers, only is 1/4 of external service life.
Some element kits also are provided with the float level sensor in the filter tank bottom, and discharging valve is installed on the sensor body.The effect of float level sensor is to realize break-make by magnetic signal when water level reach a certain height, and reports to the police, and in time discharges water to remind the driver.Yet at present the float level sensor that uses all adopts float and sensor together integrated, can't realize float is implanted in the filter tank for fuel-displaced young product.
In addition, the cleaner seat forms by die casting aluminium usually, then carries out suitable machined again.Such cleaner seat weight is big, and the high matching requirements height of machining accuracy, thereby increases production cost.In addition, owing to oil-in, oil-out etc. and pedestal integrally casting form, be unfavorable for the expansion of auxiliary function.
The mode that discharges water of cleaner is manually opened discharging valve and is made under the oil water mixture spontaneous current normally in the vertical lower of filter tank at present, can cause certain injury to the parts below it usually.If near part temperature is very high, then can cause serious consequence such as ignite.
Summary of the invention
One of purpose of the present invention just provides the low element kit of a kind of production cost, and this element kit comprises filter tank and be contained in the interior filter core of this filter tank that this filter core comprises the multilayer polyhexamethylene adipamide.Replace filter paper can reduce cost with polyhexamethylene adipamide (claim nylon 66 again, be called for short PA66) as filtering material.By hierarchy, the number of plies of PA66 layer is extremely many, is difficult for blockedly, and particle is adsorbed the back and just is difficult for breaking away from, and changes the filtration of the limited number of plies of filter paper in the past and not stratifiedly easily blocks and very fast inefficacy mutually.
In a preferred embodiment, the particle of described each layer of multilayer polyhexamethylene adipamide absorption different-grain diameter.PA66 layer of the present invention is divided into different levels to particles with different sizes and adsorbs, become step-like distribution of particles trend, ground floor filters big particle, last one deck filters little particle, and this material is even and crack, great cave can hold the particle of 4-8 times of weight of onesize papery filter core, thereby improved the life-span of present cleaner greatly, reduced the replacing of cleaner, reduced cost and the most important thing is to have reduced environmental pollution.
In a preferred embodiment, this element kit also is included in the float level sensor that install the filter tank bottom, and this float level sensor comprises float assembly and the level sensor that separates with this float assembly.In the assembling process, float assembly is installed in the filter tank from the filter tank upper shed, and level sensor is passed float assembly from the dewatering outlet insertion of filter tank bottom.The advantage of this isolating construction is: the dewatering outlet need not to increase, and is less to the influence of filter tank static pressure, easy to assembly, good seal performance.
More preferably, this float assembly comprises the float shell, is positioned at the float of this float shell, is installed in the float cover on this float shell, and described float shell, float and float cover are provided with the centre bore that passes for this level sensor.
On the other hand, the invention provides the low fuel filter of a kind of production cost, this fuel filter comprises above-mentioned element kit and fuel filter seat.
In a preferred embodiment, this fuel filter seat is made of the upper cover plate assembly, and this upper cover plate assembly comprises the upper cover plate that punching press forms and is welded on oil inlet pipe and flowline on the upper cover plate.Described upper cover plate production technology is simple, in light weight, and simple with being connected of other annexes, is suitable for expanding other functions.More preferably, described upper cover plate assembly also comprises the fairing cap that is welded on described upper cover plate bottom, this fairing cap is tightly connected with the upper end cover of element kit and is communicated with the center cavity sealing of element kit, and this flowline is communicated with the oil pocket fluid that goes out that is formed by this fairing cap.By using the fairing cap structure to realize the rational deployment of oil pipe.
In a preferred embodiment, this fuel filter comprises directed drainage arrangement, with the water directional stream-guidance, can not cause the damage of other parts.Preferably, this orientation drainage arrangement comprises: discharge valve seat is welded on the described upper cover plate; Discharging valve is installed on this discharge valve seat; And drainpipe, the one end is installed in the bottom of this discharge valve seat, and the other end leads to the filter tank bottom.
In a preferred embodiment, relief valve seat can be soldered to described upper cover plate, thereby can realize being connected with the simple of overflow valve.When the oil pressure in the cleaner surpassed certain threshold value, overflow valve was opened, and unnecessary fuel oil directly returns fuel tank from oil inlet pipe through overflow valve.
Description of drawings
Embodiment with reference to the following drawings will be more readily apparent from above-mentioned and other advantages of the present invention, in the accompanying drawings:
Fig. 1 is the stereogram of fuel filter of the present invention;
Fig. 2 is the profile of the fuel filter of Fig. 1;
The specific embodiment
Following examples only are exemplary, are not used for limiting protection scope of the present invention.Protection scope of the present invention is limited by appended claim.Obviously, those skilled in the art can carry out multiple modification or replacement to embodiments of the invention, and does not break away from the spirit and scope of the present invention.
