[0030] The catheter 1 outer side is equipped with the protective structure for protecting it.

[0031] The catheter 1 end outer side is fixedly connected with the welding ring 3 of annular structure distribution, and the both ends of catheter 1 are aligned with the hydraulic pipe 5.

[0032] The hydraulic pipe 5 is provided with a welding ring 3 at one end close to the end of the conduit 1, and the welding ring 3 on the conduit 1 and the welding ring 3 on the hydraulic pipe 5 are welded to each other.

[0034] In the pipeline installation process, first, the conduit 1 and the hydraulic pipe 5 are aligned with each other, and the welding ring 3 on the conduit 1 and the welding ring 3 on the hydraulic pipe 5 are aligned with each other, and the two aligned welding rings 3 are welded, thereby connecting the conduit 1 and the hydraulic pipe 5 to each other through the welding of the two welding rings 3, when the conduit 1 and the hydraulic pipe 5 are connected to each other through the welding of the welding ring 3, at this time, the two reinforcing flanges 4 are in close contact with each other, and the two reinforcing flanges 4 are connected to each other by bolts, at this time, the reinforcing flanges 4 will be located outside the welding ring 3 to protect the welding ring 3, and the reinforcing flanges 4 are arranged to strengthen the welding of the conduit 1 and the hydraulic pipe 5, improve the sealing of the welding, and prevent cracks and leakage caused by external force on the welding;

[0035] In the use of the conduit 1, the hydraulic oil inside will often stop suddenly or flow suddenly, the sudden stop or sudden flow of the hydraulic oil inside the conduit 1 will cause the pressure inside the conduit 1 to increase, the pressurizing valve 10 fills the gas into the inside of the pressure relief tank 2, until the piston 8 in the inside of the pressure relief tank 2 moves downward, until the pressure in the inside of the pressure relief tank 2 is in a stable state, when the pressure inside the conduit 1 suddenly increases, at this time, the hydraulic oil inside the conduit 1 will enter the inside of the pressure relief tank 2 through the bottom of the pressure relief tank 2, and push the piston 8 to slide downward in the inside of the pressure relief tank 2, thereby transferring the hydraulic oil pressure inside the conduit 1 to the inside of the pressure relief tank 2, preventing the water hammer effect caused by the sudden increase in pressure of the hydraulic oil from damaging the conduit 1.
