Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an oil filter used for bypass valve filtering. Background Art

[0002] When the engine is working, a large amount of lubricating oil is required to enter the engine. The bypass valve allows the lubricating oil to enter the interior of the engine, and then the lubricating oil takes away the heat generated by the engine, reducing the temperature of the engine. At the same time, it takes away the impurities generated by wear and tear of the engine, and can also achieve lubrication of various components to avoid dry friction of the engine.

[0003] When the engine is in urgent need of lubrication at high speed, the existing bypass valve will start, allowing unfiltered oil to flow into the engine through this valve to protect the engine. However, this unfiltered lubricating oil contains impurities produced by engine wear. If these impurities enter the engine again, they will accelerate the wear of the engine. Therefore, it is necessary to develop an oil filter for bypass valve filtering. Utility Model Content

[0004] The utility model aims to provide an oil filter for bypass valve filtering, so as to solve the technical problem that it is inconvenient to filter impurities carried in lubricating oil proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil filter for bypass valve filtering, comprising a shell, a supporting spring sheet is fixedly installed inside the shell, a magnet is arranged on one side of the supporting spring sheet, a filter screen is installed on the magnet, a filter element is arranged inside the shell, and the filter element is located on one side of the filter screen, a check valve sealing ring is arranged inside the shell, and the check valve sealing ring is located on one side of the filter element, a threaded cover plate is arranged on one side of the threaded cover plate, and a dense plate is arranged on the dense plate, and an outer sealing ring is arranged on the dense plate.

[0006] Preferably, the filter mesh is a 80 μm metal filter mesh.

[0007] Preferably, the magnet is ring-shaped.

[0008] Preferably, the supporting spring sheet is used to support the magnet and the filter screen.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model installs a filter screen and a magnet, so that the oil filter with a bypass valve can filter the metal impurities in the engine lubricating oil. The magnet and the filter screen are supported by the bottom supporting spring sheet. When the engine rotates at a high speed and urgently needs lubricating oil, the lubricating oil flows inside the oil filter with a bypass valve. Small metal impurities in the unfiltered lubricating oil will be absorbed by the magnet, and large metal impurities will be filtered out by the filter screen, thereby achieving the purpose of filtering impurities, thereby preventing impurities from entering the interior of the engine through the bypass valve, causing damage to the engine and affecting the service life of the engine.
