Abstract
The utility model discloses a spin-on diesel filter, include the shell and fix at shell open-top's upper cover plate, the upper cover plate is equipped with oil outlet and inlet port, and the oil outlet is located central authorities, and the inlet port is equipped with a plurality ofly around the oil outlet, the internally mounted filter element group spare of shell, the bottom installation drain valve of shell, its characterized in that: the periphery of the bottom of the filter element assembly is provided with a spring piece, the spring piece supports the edge of the bottom of the filter element assembly, the spring piece is obliquely arranged to enable the filter element assembly to be centrally positioned, and the spring piece is fixed on the wall of the shell. The utility model discloses leave out the setting of spring, reduce cost to guarantee that the filter element group spare makes job stabilization at the inside central point of filter location.
Description
Technical Field
The utility model relates to an improved rotary diesel filter.
Background
The diesel filter has the functions of filtering harmful impurities and moisture in a diesel system, protecting the normal work of the diesel engine, reducing abrasion, avoiding blockage and prolonging the service life of the diesel engine. The spin-on diesel filter illustrates that the diesel filter is mounted in a rotating manner. At present, a filter element assembly arranged in a shell of a spin-on diesel filter realizes the positioning of the filter element assembly through a cylindrical spring which is arranged at the bottom of the filter element and is abutted against the filter element assembly, and the required specification and size of the cylindrical spring are larger, so the manufacturing cost of the filter is increased to a greater extent; in addition, because cylindrical spring only carries out the flat support to the bottom of filter element group spare and supports, does not increase at the filter element group spare and sets up under the condition of location, the filter element group spare can be relatively poor at the inside central point of filter, and the during operation appears unstablely easily.
Disclosure of Invention
The utility model aims at providing a set up of omitting the spring, reduce cost to guarantee that filter element group spare is fixed a position at the inside center of filter, make job stabilization's spin-on formula diesel filter.
The utility model adopts the following technical proposal to complete:
Spin-on diesel filter, include the shell and fix at shell open-top's upper cover plate, the upper cover plate is equipped with oil outlet and inlet port, and the oil outlet is located central authorities, and the inlet port is equipped with a plurality ofly around the oil outlet, the internally mounted filter element group spare of shell, the bottom installation drain valve of shell, its characterized in that: the periphery of the bottom of the filter element assembly is provided with a spring piece, the spring piece supports the edge of the bottom of the filter element assembly, the spring piece is obliquely arranged to enable the filter element assembly to be centrally positioned, and the spring piece is fixed on the wall of the shell.
The spring piece is riveted or spot-welded on the wall of the shell.
The position that the upper cover plate set up the oil outlet is equipped with down the turn-ups, and the periphery of turn-ups is equipped with and encircles the anastomotic rubber circle of shape with turn-ups down, and the rubber circle has bushing portion and last turn-ups portion, and the hole of bushing portion is embraced the excircle of turn-ups down, the top surface laminating upper cover plate of going up turn-ups portion, filter element group spare includes refill, refill upper cover and refill lower cover, and the refill upper cover has to the pipe portion of going up the bulge, and the top end face elasticity of pipe portion supports the bottom surface that leans on turn-ups portion, and the hole of pipe portion is embraced the excircle of bushing portion.
According to the spin-on diesel filter in the technical scheme, the spring piece fixed on the wall of the shell is used for replacing a cylindrical spring in the prior art to elastically support the filter element assembly, and the filter element assembly can be well positioned after being installed due to the inclined arrangement of the spring piece, so that the spin-on diesel filter has the advantages that the spring is omitted, and the cost is reduced; secondly, the filter element component is ensured to be positioned at the center inside the filter, so that the work is stable. In addition, the setting of the sleeve part of rubber circle, the pipe portion of going up turn-ups portion and filter element group spare refill upper cover can guarantee filter internal seal at first, prevents oil feed, the mutual seepage between producing oil, and secondly makes the filter element group spare obtain central positioning inside the filter from the top direction of filter element group spare, makes job stabilization.
Drawings
The utility model discloses there is following figure:
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a spin-on diesel filter, include shell 7 and fix at 7 open-top's of shell upper cover plate 6, upper cover plate 6 is equipped with oil outlet 4 and inlet port 5, oil outlet 4 is located central authorities, inlet port 5 is equipped with a plurality ofly around oil outlet 4, the internally mounted filter element group spare 8 of shell 7, the bottom installation valve 11 that drains of shell 7, the bottom periphery of filter element group spare 8 is equipped with four spring leafs 10, spring leaf 10 is made by spring plate, spring leaf 10 holds the bottom edge of filter element group spare 8, spring leaf 10 slope sets up makes filter element group spare 8 obtain the center location, spring leaf 10 is in through rivet 9 riveting fixed (or spot welding fixed) on the conch wall of shell 7. The position that upper cover plate 6 set up oil outlet 4 is equipped with down the turn-ups 3, and the periphery of turn-ups 3 down is equipped with and encircles 3 anastomotic rubber circle 2 of shape of turn-ups, and rubber circle 2 has bushing portion and last turn-ups portion, and the hole of bushing portion is embraced down the excircle of turn-ups 3, the top surface laminating upper cover plate 6 of going up turn-ups portion, filter element group spare 8 includes refill, refill upper cover and refill lower cover, and the refill upper cover has to the pipe portion 1 of rising, and the top end face elasticity of pipe portion 1 supports the bottom surface of leaning on turn-ups portion, and the hole of pipe portion 1 is embraced the excircle of bushing portion.
