Abstract

The utility model relates to a fuel filter, which comprises a housing body and a filter layer arranged in the housing body. The fuel filter is characterized in that the housing body is cylindrical with one end equipped with an oil pipe connector and the other end open, the opening is equipped with a detachable end cap, the side wall of the housing body is provided with meshes, the filter layer is a cylinder, and the center of the filter layer has a through hole which is coaxial with the center of the filter layer. The filter layer of the fuel filter can be conveniently separately replaced if contaminated, and the housing body and the other parts can be reused, thereby greatly reducing operating and maintaining cost.

Description

Fuel oil filter

Technical field

The utility model relates to a kind of fuel oil filter.

Background technique

Petrol engine machine, diesel engine etc. are used with the precision optical machinery of fuel oil as power mostly to be needed fuel oil is filtered use later on.Existing fuel oil filter all is the expendable consumed product of sealing, whole filter need be changed in the time of replacing.Waste bigger.

Summary of the invention

At the bottom of the purpose of this utility model provides a kind of cost, easy to use, the fuel oil filter that can change filter layer separately.

For achieving the above object, the utility model adopts following technological scheme:

Fuel oil filter described in the utility model comprises housing and the filter layer that is installed in the housing, and it is characterized in that: housing is cylindric, and the one end has tubing interface, and the other end opening, opening are equipped with detachable end cap, has mesh on the sidewall of housing; Filter layer is a cylindrical body, and the center of filter layer has the through hole coaxial with it.

The bob piece is installed in the housing of end cap inboard, and the bob piece is a cylindrical body, and its center has the round platform of projection, and the diameter of round platform is identical with the through-hole diameter at filter layer center.

After adopting technique scheme, can change separately easily after filter layer is dirty, other parts such as shell are reusable, greatly reduce the equipment operation maintenance cost.

Description of drawings

Fig. 1 is an embodiment's of the utility model a structural representation;

Fig. 2 is the A-A sectional view of Fig. 1.

Embodiment

As shown in drawings, fuel oil filter described in the utility model comprises housing 1 and the filter layer 2 that is installed in the housing 1.Housing 1 is plastics or metal cylindric, the one end has tubing interface 11, the other end opening, at opening detachable end cap 3 is installed, end cap 3 is made for plastics or metal, be connected on the housing 1 by the hook 13 that is arranged on housing 1 outer wall, the hand disassembly end cap 3 so easily, need be by instrument.Have mesh 12 on the sidewall of housing 1, mesh 12 can be an Any shape, also the sidewall design of housing 1 can be reticulated, can make things convenient for like this fuel oil by and prevent that filter layer 2 wherein from dropping out; Filter layer 2 is cylindrical bodys that the material that adopts felt, sponge etc. to have irregular pore is made, and its diameter matches with the internal diameter of housing 1, just in time can be installed in the housing 1, and the center of filter layer 2 has the through hole coaxial with it 21.

Be equipped with in the housing 1 of end cap 3 inboards and weigh down piece 4, weigh down the cylindrical body that piece 4 is made for the bigger materials such as metal of proportion, its center has the round platform of projection, and the diameter of round platform is identical with the through-hole diameter at filter layer 2 centers.Weigh down the effect one convenient weight that can increase whole filter of piece 4, make it in work, can sink to the fuel tank bottom,, fill up the inner space of housing 1, prevent that fuel oil from passing through from the space, improve the effect of filtering on the other hand by press filtration layer 2.

During use, tubing interface 11 promptly can use as filler opening and also can be used as the oil outlet use.When tubing interface 11 as filler opening the time, fuel oil enters housing 1 by tubing interface 11, arrives the central through bore 21 of filter layer 2 again, and filters out the wherein bigger impurity of particle in the sidewall that passes filter layer 2.The fuel oil of cleaning passes the sidewall of filter layer 2, and the mesh 12 from housing 1 sidewall oozes out, and reaches the purpose of filter fuel.

Otherwise when tubing interface 11 as oil outlet the time, the negative pressure that produces in the oil pipe is drawn onto the outside of fuel oil from housing 1 central through bore 21 of housing 1 inside, filter layer 2, filters out the wherein bigger impurity of particle in the sidewall by filter layer 2.Qing Jie fuel oil is delivered in the oil pipe by tubing interface 11 at last, and supply equipment uses.

After filter layer 2 usefulness are dirty, as long as open end cap 3, take out and weigh down piece 4 and filter layer 2, change after the filter layer 2 of same model, new filter layer 2 and bob piece 4 are reloaded in the housing 1, cover end cap 3, can reuse.
