Abstract

The invention discloses a threaded filter, which is characterized in that the threaded filter comprises a filter shell 1, a thread-type filter element 2, a closing ring 3, a liquid inlet 4 and a liquid outlet 5; the thread-type filter element 2 comprises an A liquid channel 6, a B liquid channel 7 and a filtering thread 8; wherein, the thread-type filter element 2 is arranged in the filter shell 1; the closing ring 3 is arranged at one side of the shell; two ends of the filter shell 1 are respectively communicated with the liquid inlet 4 and the liquid outlet 5. The threaded filter has the advantages that the threaded filter changes the traditional mode in which the liquid is filtered, has improved filtering performance, and thus can be applied to the liquid filtering system for fuel, lubricating oil and water supply, etc.

Description

technical field [0001] The invention relates to the mechanical field, and in particular provides a threaded filter. Background technique [0002] In order to remove impurities such as particles and silk in the liquid, a filter device must be installed in the liquid supply system. At present, the filter generally used in the industry is a filter with a metal mesh structure. By adjusting the gap of the metal mesh, it can meet the requirements of different filtration accuracy. From a structural point of view, the filter structure of the metal mesh structure is relatively complicated, especially for the filter element. In order to fix the metal mesh, it is generally necessary to design a special metal bracket. In the process of use, the filtered impurities are not easy to remove, especially the filtered impurities such as silk and wool, which are more difficult to remove when hanging on the metal mesh, and it is easy to cause damage to the metal mesh. If the metal mesh is damag...
