Description
Technical field
The utility model belongs to engine fuel supply technology, relates to the improvement to the fuel oil coarse-grain filtering device.
Background technique
Existing fuel oil coarse-grain filtering device, a kind of product of producing of Pingyuan Filters Co., Ltd for example, its structure is as shown in Figure 1.It is made up of pedestal 1, flange 2, filter core 3, housing 4, sediment bowl 5 and fuel outlet valve 6, and pedestal 1 and filter core 3 and filter core 3 and sediment bowl 5 are all by being threaded.Fuel outlet valve 6 is positioned at sediment bowl 5 bottom surface central authorities.There is oil inlet hole to be communicated with on the pedestal 1 with annular housing between housing 4 and the filter core 3.The inner chamber of filter core 3 is communicated with oil outlet on the pedestal 1.The granule foreign of this fuel oil coarse-grain filtering device in can only filter fuel, the moisture in can not separating oil.Its housing is opaque, can't observe the situation of filter interior.
Summary of the invention
The purpose of this utility model is: provide a kind of can impurity screening, can separate the fuel oil coarse-grain filtering device of moisture again, can observe the ponding situation of filter interior simultaneously, be convenient to safeguard.
The technical solution of the utility model is: a kind of fuel oil coarse-grain filtering device, by pedestal 1, housing 7, element kit 8, spring 9, fastening nut 10, retaining ring 11 and fastening screw trip bolt 12 are formed, there is a circular groove lower end surface of pedestal 1, the upper end of housing 7 embeds in this groove, between housing 7 and pedestal 1, seal ring is arranged, oil inlet hole and oil outlet are arranged on the pedestal 1, element kit 8 is positioned at housing 7 centers, the center oil outlet tube of element kit 8 is connected with oil outlet on the pedestal 1 and seals, oil inlet hole on the pedestal 1 and housing 7 inwalls are communicated with annular housing between the element kit 8, a spring 9 is arranged in the lower end surface of housing 7, a retaining ring 11 of being made by wire or bar that bends to approximate V-type is arranged, there is hook two terminations of retaining ring 11 upper ends, hang in the hook hole of pedestal 1 side, lower end at retaining ring 11 connects a fastening screw trip bolt 12, fastening nut 10 is screwed on the fastening screw trip bolt 12, withstand the lower end surface of housing 7, housing 7 and pedestal 1 are firmly connected into integral body, it is characterized in that, it is the polypropylene square hole net manufacturing of 20～35 ц m that filter core in the said element kit 8 adopts precision, scribbles the hydrophobic material polytetrafluoroethylene on the surface of polypropylene square hole net.
The utility model has the advantages that: adopted novel filter core, effectively the moisture in the separating oil.Housing adopts transparent plastics manufacturing, and isolated water accumulating volume in the convenient observation filter is convenient to safeguard.
Description of drawings
Fig. 1 is the structural representation of existing a kind of fuel oil coarse-grain filtering device.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below the utility model is described in further details.Referring to Fig. 2, the utility model is made up of pedestal 1, housing 7, element kit 8, spring 9, fastening nut 10, retaining ring 11 and fastening screw trip bolt 12.There is a circular groove lower end surface of pedestal 1, and the upper end of housing 7 embeds in this groove.Between housing 7 and pedestal 1, seal ring is arranged.Oil inlet hole and oil outlet are arranged on the pedestal 1.Element kit 8 is positioned at housing 7 centers, and the center oil outlet tube of element kit 8 is connected with oil outlet on the pedestal 1 and seals.Oil inlet hole on the pedestal 1 and housing 7 inwalls are communicated with annular housing between the element kit 8.A spring 9 is arranged in the lower end surface of housing 7.A retaining ring 11 of being made by wire or bar that bends to approximate V-type is arranged, and there is hook two terminations of retaining ring 11 upper ends, hang in the hook hole of pedestal 1 side.Lower end at retaining ring 11 connects a fastening screw trip bolt 12, and fastening nut 10 is screwed on the fastening screw trip bolt 12, withstands the lower end surface of housing 7, and housing 7 and pedestal 1 are firmly connected into integral body.Of the present utility model being characterised in that, it is the polypropylene square hole net manufacturing of 20～35 ц m that the filter core in the said element kit 8 adopts precision, scribbles the hydrophobic material polytetrafluoroethylene on the surface of polypropylene square hole net.The structure of element kit 8 adopts technique known, by a skeleton that has an oil outlet tube, be wrapped in the outer filter core of skeleton and up and down end cap form.
Working principle of the present utility model is: fuel oil is entered by the filler opening on the pedestal 1, flows to the outside of housing 7 inner filter core assemblies 8, through the filtration of filter core, flows in the inner chamber of element kit 8.Because the hydrophobicity of filter core, the moisture in the fuel oil can not enter the inner chamber of element kit 8, is separated from fuel oil, stays in the annular cavity.The moisture of separating accumulates in lower housing portion under the influence of deadweight.When safeguarding, unscrew fastening nut 10, moisture can be emitted.Fuel oil after filtration is by the inner chamber of the element kit 8 oil outlet outflow filter by oil outlet tube and pedestal 1.
For the ease of observing the ponding situation of filter interior, said housing 7 adopts transparent plastics manufacturing.
