Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-3, a structure of a bypass filter comprises a housing 1, wherein the housing 1 is a cylindrical structure with an open upper end, a mounting frame 3 is screwed at the bottom of the housing 1, an oil filling mounting hole is formed in the mounting frame 3 and used for mounting the filter on mechanical equipment, a cover body 2 is mounted on the housing 1, a pressure measuring hole 4 is formed in the middle of the cover body 2, a bolt can be mounted in the pressure measuring hole 4 to prevent oil from flowing out, and a pressure gauge can be mounted to check the pressure condition of the oil in the housing 1 so as to judge whether a filter element 6 is blocked;

an annular sealing element 5 is arranged at the contact position of the shell 1 and the cover body 2, the annular sealing element 5 can be an O-shaped sealing ring to prevent oil leakage, a filter element 6 is arranged inside the shell 1 and used for filtering water and impurities in oil, an oil inlet hole 7 is formed in the middle of the filter element 6, the oil inlet hole 7 is of a tubular structure and is integrally formed with the shell 1, a bypass valve assembly 11 is arranged inside the oil inlet hole 7, the oil flows in from the oil inlet hole 7, when the preset pressure is reached, the bypass valve assembly 11 is communicated, and the oil flows into the shell 1 from the oil inlet hole 7;

an oil through groove 9 is formed in the bottom of the inner side of the shell 1, the structure of the oil through groove 9 is similar to that of an annular pressure plate 12, oil filtered by the filter element 6 flows into the oil outlet hole 8 from the oil through groove 9, the bottom of the oil through groove 9 is communicated with the oil outlet hole 8, the oil flows out of the oil outlet hole 8, the number of the oil outlet holes 8 is two, the oil outlet holes can be connected with two oil outlet pipes, one of the oil outlet pipes can be connected with one of the oil outlet pipes, and the other oil outlet pipe is provided with a pressure gauge for judging the blocking condition of the filter element 6;
