Product Description

Teflon gaskets are called PTFE gaskets or Teflon gaskets abroad. They are flat gaskets, V-shaped gaskets, piston rings and ball valve gaskets made of PTFE rods, tubes and plates by mechanical turning or cutting. In fluid machinery (such as pumps, compressors, mixing kettles, centrifuges, etc.), the most stringent working conditions are tetrafluoro gaskets.

Teflon gaskets are called PTFE gaskets or Teflon gaskets abroad. They are flat gaskets, V-shaped gaskets, piston rings and ball valve gaskets made of PTFE rods, tubes and plates by mechanical turning or cutting. It has good properties of corrosion resistance, aging resistance and non-conductivity. The pH value of PTFE is 0-14 (except for molten alkali metals and fluorine at high temperature and high pressure). It has good mechanical strength between - 100 C and 100 C.

Importance Severity In fluid machinery (such as pumps, compressors, mixing kettles, centrifuges, etc.), the most stringent working conditions are tetrafluoro gaskets. (1) Accept the axial force as thrust bearings do; (2) Export the heat generated like a radiator; (3) In the case of high temperature, high pressure and easy corrosion, the static seal is now very difficult, but also in the high-speed rotation, it is more difficult to complete the dynamic seal on the sealing surface of several millimeters. Working environment (1) Without an auxiliary system, only the sealing layout can be improved and raw materials can be improved. (The cost is too high to solve the problem fundamentally) (2) In practice, there are almost no tetrafluoro gaskets without any auxiliary equipment. For example, the series tetrafluoro gaskets and high temperature tetrafluoro gaskets used under high pressure must be equipped with corresponding auxiliary equipment. (3) The rigorous working condition is changed to the acceptable sealing condition. (The function of tetrafluoro gaskets has been greatly improved, the scope of application has been wider and wider, the demand for sealing data has been reduced, and the cost of tetrafluoro gaskets has been reduced) [2] Manipulation The excessive heat of end-to-end conflict has the following damage: (1) Vaporization wear of liquid film aggravates seal failure; (2) The thermal deformation of the end increases leakage and wear. (3) aggravating corrosion; (4) Auxiliary sealing ring aging and degeneration and then failure; (5) Leakage occurs when graphite impregnates are carbonized or melted. Therefore, the end temperature rise is the enemy of tetrafluoro gaskets.

Auxiliary system (1) Reduce temperature rise, adhere to the outstanding smooth end surface. (Make each part of the tetrafluoro gasket outstanding, normal operation) (2) Insist that the pressure of the sealing chamber is higher than that of the full steam in the vaporizable medium so as not to vaporize. (3) Insulation heating in low temperature pumps. (4) With regard to the crystallization of solid particles and the sealing of strong corrosive media, the sealing can be maintained without damage. 5. Under better working conditions, the selection of auxiliary system will improve the sealing stability and service life. (Some sealing operation temperature, pressure, speed is not too high. Operating without supporting systems) 6. Auxiliary system belongs to the component of tetrafluoro gasket
