[0002] The four fluorine packing is woven by pure polytetrafluoroethylene fiber through a weaving device and is not treated by PTFE emulsion and lubricating grease. Since it is woven by solid and has flexibility and adjustability, it can be well matched with the shaft and the stuffing box and has excellent corrosion resistance, good self-lubricating property and anti-sticking property. It can be used in operating fields such as chemical industry, food, medicine, papermaking, chemical fiber and fine chemical industry which do not allow pollution.

Since the material of the O-ring product is limited to EPDM or silicone, the corrosion resistance and high temperature resistance are slightly poor. The rubber ring will fail under high temperature, and the compression of the rubber ring will also occur under high water pressure. Therefore, a high water pressure and high temperature resistant sealing structure is needed to solve the above problems. SUMMARY

[0007] Preferably, a plurality of leakage prevention pads are arranged, and the sizes of the leakage prevention pads are not limited.

[0008] Preferably, the leakage prevention pad is made of four fluorine packing, and the connecting screw pipe can apply pressure downward through the metal compression ring to deform the leakage prevention pad inward and outward, so as to increase the sealing surface to resist high water pressure and water leakage.

[0009] The high water pressure resistant and high temperature resistant sealing structure provided by the utility model adopts industrial sealing medium four pack, the increase of the sealing surface can effectively resist the water leakage problem of high water pressure, and the change of temperature will not affect the material failure, and the sealing water is realized by increasing the metal part upward to apply pressure to the pack to cause deformation, and the practicability is high.
