Its useful life, oil filter should have that filtering ability is strong, and circulating resistance is little, service life the performance such as length, the machine oil of high-quality
Cleaner has bypass valve, when external temperature is reduced to a certain particular value or when oil filter is beyond normal useful life
Time, bypass valve can be opened under particular pressure effect, allows the machine oil of filtered flow directly into electromotor, and however one,
Impurity in machine oil can enter electromotor, but compared with the loss not having machine oil in electromotor and cause for, it is much smaller, because of
This bypass valve is the key in case of emergency protecting electromotor, but in traditional cleaner, bypass valve is arranged on machine oil
In the aluminum seat of filter, but such structure is the compactest, installs and the most more bothers, therefore, it is necessary to improve oil filtration
Device, the bypass valve arrangement making this oil strainer is compact, easy for installation.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one proposed is with bypass valve
Oil filter.
To achieve these goals, this utility model adopts the technical scheme that
A kind of oil filter with bypass valve, including housing, is provided with the cavity of upper end open in described housing,
The opening part of cavity is provided with cover plate, is provided with one group of fuel feed hole on described cover plate, is additionally provided with an oil outlet on described cover plate,
Pick out oil pipe in described oil outlet inner sleeve, be provided with filter element in the lower end of described cover plate, it is characterised in that: in the lower end of described filter element
Face is provided with a through hole, one bypass valve of corresponding matching in described through hole.
Preferably, described filter element includes central canal, is respectively cooperating with at the two ends of central canal connecting upper end cover and bottom end cover,
The filter paper of the outside socket tubular of central canal.
Preferably, being provided with check-valves between described cover plate and upper end cover, described check-valves is socketed in outside oil inlet pipe.
Preferably, between the lower section and housing of described bypass valve, be provided with spring, the two ends up and down of described spring respectively with
Bypass valve and position, housing top coordinate.
Preferably, at the upper surface nesting sealing ring of described cover plate.
The utility model has the advantage of: this device is by being fixed on bypass valve on filter element lid so that the knot of bypass valve
Structure is the compactest, installs more convenient, simplifies displacement configuration, uses less parts, thus more cost-effective.

Fig. 2 is the isometric view of Fig. 1.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As depicted in figs. 1 and 2, a kind of oil filter with bypass valve that this utility model provides, including housing 1,
Described housing 1 is cylindrical structure, is provided with the sphere of outwardly convex in its lower surface, is provided with upper end open in described housing 1
Cavity 1.1, be provided with one section of screw thread 1.2 on the top of described cavity 1.1, in described cavity 1.1 by screw thread 1.2 connect lid
Plate 2, described cover plate 2 is cake type structure, and on the surface of cover plate 2, uniform four fuel feed holes 3, also set at the center of described cover plate 2
Having an oil outlet 4, be socketed one section of flowline 12 in described oil outlet 4, described flowline 12 is extended to shell by housing 1 is internal
Body 1 is outside, and for ensureing device sealing, described cover plate 2 and flowline 12 use integrated punching fabrication techniques to complete.
Be provided with filter element 5 in the lower end of described cover plate 2, described filter element 5 includes upper end cover 7 and bottom end cover 8, at described upper end cover
The surface of 7 is provided with access opening 7.1, described access opening 7.1 and flowline 12 corresponding matching, at the centre of surface of described bottom end cover 8
Position is provided with valve opening 8.1, and fixing connection central canal 9 between described upper end cover 7 and bottom end cover 8, described central canal 9 is cylinder
Pipe, has one group of through hole 9.1 on cylindrical tube surface, and described through hole 9.1 enters the inside of central canal 9 smoothly for environmental liquids,
The outside of described central canal 9 socket tubular filter paper 10, the two ends up and down of described filter paper 10 respectively with upper end cover 7 and bottom end cover
8 fixing connections, and paste on the surface of central canal 9, so the benefit of design is the intensity that central canal 9 can increase filter paper 10,
Filter paper 10 is made to avoid damaged because oil pressure increases.
