Technical Field

[0001] The utility model belongs to the technical field of sealing gaskets, in particular to a high-performance sealing gasket for a high-pressure fluid pipeline. Background Art

[0002] High-pressure fluid pipelines are pipeline systems used to transport high-pressure fluids. These pipeline systems are usually used in industrial fields such as petroleum, natural gas, chemicals, and electricity, as well as in infrastructure construction such as urban water supply and drainage. In high-pressure fluid pipelines, sealing gaskets play a vital role. They are installed at pipeline connections, such as flange connections, threaded connections, etc., to prevent fluid leakage and ensure the safe operation of the pipeline system.

[0003] In high-pressure fluid pipelines, due to pressure fluctuations or shocks of the fluid, sealing gaskets may be subjected to instantaneous pressure peaks. These peak pressures are often much higher than the normal working pressure. This high-pressure shock may cause the gasket to deform, thereby reducing its sealing performance. Utility Model Content

[0008] Preferably, the outer side of the guide block is symmetrically rotatably connected to two movable rods, and one end of the two movable rods away from the guide block is rotatably connected to the two side blocks respectively.

[0009] Preferably, the anti-slip mechanism comprises two anti-slip rings symmetrically located outside the metal ring, the two sealing pads are located between the two anti-slip rings, and anti-slip protrusions are fixedly installed at equal distances on the sides of the two anti-slip rings away from each other.

[0010] Preferably, two connecting rods are fixedly installed at equal distances on one side of the anti-slip ring close to the second sealing pad, and one end of each connecting rod far away from the anti-slip ring passes through the second sealing pad and is fixedly installed with a slider, and each connecting rod is movably connected to the second sealing pad, and the slider is movably sleeved on the outer side of the reinforcing rod, and two springs are fixedly connected between the slider and the sleeve plate, and the two springs are sleeved on the outer side of the reinforcing rod.
