[0021] In the embodiment, the design of the above structure can effectively protect the aluminum pipe connecting welding point on the oil cooling machine compared with the traditional oil cooling machine, effectively prevent the risk of oil leakage caused by pipe explosion, and effectively save the installation space of the equipment due to the compactness of the structure.

[0022] Specifically, the upper end of the valve seat 1 is provided with a second assembly groove 9, and the first aluminum pipe 2 is fixedly welded in the second assembly groove 9.

[0023] In the embodiment, the second assembly groove 9 and the first aluminum pipe 2 are installation and connection modes between the valve seat 1 and the aluminum pipeline of the oil cooling machine.

[0024] Specifically, the first assembly groove 6 is formed in one side of the valve seat 1, and the second aluminum pipe 3 is fixedly welded in the first assembly groove 6.

[0025] In the embodiment, the first assembly groove 6 and the second aluminum pipe 3 are installation and connection modes between the valve seat 1 and the aluminum pipeline of the oil cooling machine.

[0026] Specifically, the second through groove 10 is formed in the inside of the valve seat 1 below the second assembly groove 9, the first through groove 7 is formed in one side of the inside of the valve seat 1 below the first assembly groove 6, and the first through groove 7 and the second through groove 10 are mutually penetrated with the valve core assembly groove 8.

[0027] In the embodiment, the second through groove 10, the first through groove 7 and the penetration connection relationship between the valve core assembly groove 8 make the aluminum pipeline on one side of the equipment and the aluminum pipeline on the other side form a passage.

[0028] Specifically, the oil seal valve head 13 is fixedly arranged at the front end of the valve core 17, and the oil seal valve head 13 and the first through groove 7 are mutually sealed and fitted.

[0029] In the embodiment, the oil seal valve head 13 and the sealed fitting relationship between the first through groove 7 facilitate sealing and separating the first through groove 7 and the valve core assembly groove 8 through the oil seal valve head 13.

[0030] Specifically, the side of the valve core 17 is equidistantly provided with a plurality of sealing grooves 12.

[0031] In the embodiment, the sealing grooves 12 arranged on the side of the valve core 17 can ensure the sealing between the valve core assembly groove 8 and the threaded assembly groove 11 when the valve core 17 slides to release pressure in the valve core assembly groove 8.

[0034] The working principle and use process of the utility model are as follows: when the oil pressure in the second aluminum pipe 3 on the equipment side in the oil cooling machine increases to offset the pressure of the reset spring 14 on the valve core 17, the oil in the second aluminum pipe 3 pushes the oil seal valve head 13 in the valve core assembly groove 8 to retreat and slide, so that the oil flows from the second aluminum pipe 3 with high oil pressure to the first aluminum pipe 2, the oil circuit of the equipment is released, and the structure protection of the aluminum pipe welding point is achieved.

[0035] Meanwhile, after the pressure relief is completed, when the oil pressure on one side of the second aluminum pipe 3 is insufficient to offset the pressure of the reset spring 13 on the valve core 17, the reset spring 14 pushes the valve core 17 to slide to one side of the second aluminum pipe 3, so that the oil seal valve head 13 is sealingly attached to the first through groove 7 again, which can effectively prevent the oil in the first aluminum pipe 2 from flowing back to the second aluminum pipe 3 after pressure relief, and plays a one-way oil backflow prevention role.

[0036] As described above, the overall structure design can effectively protect the aluminum pipe connection welding point on the oil cooling machine compared with the traditional oil cooling machine, effectively prevent the risk of pipe explosion and oil leakage, and effectively save the installation space of the equipment due to the compactness of the structure.
