Description

Novel fuel filter

Technical Field

The utility model belongs to the technical field of the filter, concretely relates to novel fire oil filter.

Background

The filter is a filter that filters impurities or gas through filter paper. Generally referred to as an automobile filter, is an engine accessory. The filter has different filtering functions including oil filter, fuel filter, air conditioner filter, etc. In order to make the lubricating oil flow smoothly and prevent impurities from scratching and galling the surface of a part, the engine oil in the lubricating system must be strictly filtered before being sent to a friction surface. The filter is used for filtering harmful particles and moisture in an engine fuel gas system so as to protect an oil pump nozzle tip, a cylinder sleeve, a piston ring and the like, reduce abrasion and avoid blockage. The iron oxide contained in the fuel oil is filtered. In the long-time working process, a large amount of harmful particles can be remained in the filter, and the filtering and dust removing effects of the filter are seriously influenced.

The blockage of the gasoline filter can lead to insufficient fuel supply of an engine after long-time replacement, so that the power of the engine is reduced and even the engine can not be started, the existing filter is easy to block, the blockage cannot be found easily, and the problems of difficult filter element replacement and the like are solved.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

a novel fuel filter comprises a frame body, a bottom cover, a flow guide bracket and a filter piece; the lower end of the frame body is provided with an opening, the middle part of the upper end of the frame body is concave, and an oil inlet is formed in the concave part; the bottom cover is in threaded connection with the opening; the middle of the bottom cover is concave, and a threaded port is formed in the concave part;

the flow guide support comprises a threaded cylinder and a threaded column; the outer ring of the threaded cylinder is provided with threads, and the top of the threaded cylinder is provided with a limit ring; the top of the limiting ring is connected with the bottom of the threaded column through a supporting arc piece; a filter element is sleeved between the limiting ring and the threaded column; the threaded column is provided with a limit nut;

the flow guide support is connected with the inner port of the threaded port through the threaded cylinder, the threaded cylinder extends out of the bottom cover, the bottom end of the limiting ring is clamped on the inner side of the concave part in the bottom cover, and the threaded cylinder extending out of the bottom cover is provided with the locknut.

As a further technical improvement, the oil inlet is provided with a one-way valve.

As a further technical improvement, the bottom end of the limiting ring is provided with a sealing ring A.

As a further technical improvement, a sealing ring B is arranged in the bottom cover at a position corresponding to the lower end port of the frame body.

The utility model discloses a theory of operation:

when the bottom cover is installed, the flow guide support is installed on the inner side of the bottom cover and is tightly twisted, then the locknut on the outer side of the bottom cover is installed and is tightly twisted, and then the bottom cover is tightly twisted to the opening at the lower end of the frame body; the oil inlet flows in the fuel, discharges in flowing into the screw thread section of thick bamboo of water conservancy diversion support again through filtering, and the fuel of inflow is impurity such as subsidiary dust particle, filters the piece and can filters the fuel, adsorbs tiny dust on filtering the piece, and great particle impurity then can be filtered the piece separation, sinks to the bottommost (whole filter is just putting or is put conversely) of bottom cover bottom or framework indent, can not deposit the bottom of filtering the piece too soon, causes the jam.

Compared with the prior art, the utility model has the advantages and beneficial effect as follows:

1. the utility model discloses a with the middle indent and the bottom middle part indent at framework top, provide a deposition area that great granule impurity can't adsorb on filtering, prevent that great granule impurity is too early to pile up the bottom of filtering, cause the outer jam of filter core, improve the life of filter core.

2. The utility model discloses a transparent plastics material is adopted to the framework, when navigating mate car power descends or can't start, can see through the intensive degree of transparent plastics material framework observation filter core or filter core bottom dust granule, judges whether the filter appears blockking up, does the work of verifying on next step again.

3. The utility model discloses an inboard bottom installs the water conservancy diversion support through threaded connection, and the jam nut is pretended to the outside, again with bottom and framework threaded connection, the water conservancy diversion support is then fixed through stop nut, and the connected mode that each component adopted is simple and practical, and the renew cartridge is swift convenient.

4. This real novel with adopting multiple sealing washer, effectively prevent that the fuel from exposing, and whole device simple structure, scientific and practical.
