Background technology
nullIn engine working process，Metal filings、Dust、Carbon distribution oxidized under high temperature and gelatinous precipitate、Water etc. are constantly mixed into lubricating oil，The effect of oil filter filters these mechanical admixtures and colloid exactly，Protect the cleaning of oil to be lubricated，Extend its useful life，It is strong that oil filter should have filtering ability，Circulating resistance is little，Service life the performance such as length，The oil filter of high-quality has bypass valve，When external temperature is reduced to a certain particular value or when oil filter is beyond normal useful life，Bypass valve can be opened under particular pressure effect，The machine oil allowing filtered flows directly into electromotor，However one，Impurity in machine oil can enter electromotor，But for the loss not having machine oil in electromotor and cause，It is much smaller，Therefore bypass valve is the key in case of emergency protecting electromotor，But in traditional cleaner，Bypass valve is arranged in the aluminum seat of oil strainer，But such structure is the compactest，Install and the most more bother，Therefore，It is necessary to improve oil strainer，The bypass valve arrangement making this oil strainer is compact，Easy for installation.
Summary of the invention
The invention aims to solve shortcoming present in prior art, and a kind of oil filter with bypass valve proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of oil filter with bypass valve, including housing, the cavity of upper end open it is provided with in described housing, opening part at 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, oil pipe is picked out in described oil outlet inner sleeve, it is provided with filter element in the lower end of described cover plate, it is characterised in that: it is provided with a through hole in the lower surface of described filter element, 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, at the filter paper of the outside of central canal socket tubular.
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, being provided with spring between the lower section and housing of described bypass valve, the two ends up and down of described spring coordinate with bypass valve and position, housing top respectively.
Preferably, at the upper surface nesting sealing ring of described cover plate.
It is an advantage of the current invention that: this device is by being fixed on bypass valve on filter element lid so that the structure of bypass valve is the compactest, installs more convenient, simplifies displacement configuration, uses less parts, thus more cost-effective.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of oil filter with bypass valve that the present invention provides, including housing 1, described housing 1 is cylindrical structure, the sphere of outwardly convex it is provided with in its lower surface, the cavity 1.1 of upper end open it is provided with in described housing 1, it is provided with one section of screw thread 1.2 on the top of described cavity 1.1, cover plate 2 is connected by screw thread 1.2 in described cavity 1.1, described cover plate 2 is cake type structure, uniform four fuel feed holes 3 on the surface of cover plate 2, it is additionally provided with an oil outlet 4 at the center of described cover plate 2, one section of flowline 12 it is socketed in described oil outlet 4, described flowline 12 is extended to housing 1 outside by housing 1 is internal, for ensureing device sealing, described cover plate 2 and flowline 12 use integrated punching fabrication techniques to complete.
nullIt is 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，It is provided with access opening 7.1 on the surface of described upper end cover 7，Described access opening 7.1 and flowline 12 corresponding matching，It is provided with valve opening 8.1 in the centre of surface position of described bottom end cover 8，Fixing connection central canal 9 between described upper end cover 7 and bottom end cover 8，Described central canal 9 is cylindrical tube，One group of through hole 9.1 is had on cylindrical tube surface，Described through hole 9.1 enters the inside of central canal 9 smoothly for environmental liquids，Filter paper 10 at the outside of described central canal 9 socket tubular，The two ends up and down of described filter paper 10 are fixed be connected with upper end covers 7 and bottom end cover 8 respectively，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.
It is additionally provided with check-valves 11 between described cover plate 2 and upper end cover 7, described check-valves 11 is socketed in outside oil inlet pipe 12, and with access opening 7.1 corresponding matching, the effect of described check-valves 11 is to prevent the machine oil inside cleaner from draining off, ensure whenever cleaner is internal and be full of machine oil, when electromotor is again started up, machine oil almost can arrive engine block moment and is lubricated, and described check-valves 11 uses prior art.
One bypass valve 6 of fixing connection in the lower surface of described bottom end cover 8, described bypass valve 6 and valve opening 8.1 corresponding matching, bypass valve 6 uses prior art, the effect of described bypass valve 6 be when the filter element 5 in cleaner due to impurity too much and blocked time, pressure in cavity 1.1 increases, bypass valve 6 is promoted to open, lubricating oil is lubricated in directly being entered electromotor by central canal 9 without filter element 5, bypass valve 6 designs for emergency lubrcation, for avoiding causing electromotor that more serious dry wear occurs because lacking lubricating oil.
