 ,  ,  ,  ,, the ring stress caused by 4 factors in the actual operating conditions, it can be seen that the residual stress and the internal pressure of the force in the total ring to stress, and the temperature stress in the near inner diameter side of the total ring to stress, near the outer diameter side is the opposite.
in which the flexible graphite to the composite pad has a better compression rebound performance, metal skeleton to withstand high pressure, and the formation of a multi wire seal, improve the sealing pressure, so that in extreme conditions also have excellent sealing performance through the analysis of the above, it can be known that the actual effect of the combination pad is mainly: bolt pre tightening force, temperature stress, residual stress and internal pressure. As mentioned above, the stress in the stress corrosion cracking is the normal stress, so the stress of the four in the ring is analyzed. The main
tooth combination pad for metal tooth and skeleton of flexible graphite, coated with a layer of adhesive between the two. The sealing function of the
composite pad is mainly realized by the O shaped ring, and the wave tooth structure is easy to be installed and positioned, and it has the function of sealing and preventing the O ring being pressed.
composite cushion by force, the O shaped ring at first bearing deformation after the formation of the initial seal, in the O shaped ring to seal the role of the composite structure under the pressure of the wave, the surface of the corrugated part of the surface of the graphite layer to consider processing and reduce the cost, O - shaped ring reference standard, use the inside open. The new type of composite cushion wave tooth part can be treated by non - standard parts, and its structure size can be determined according to the requirements and reference standards.
composite cushion is 0.25mm, 0.5mm, 0.8r', B, nm, size of the composite frame can be known, the wall thickness is smaller, the O shaped ring is larger, and the compression is better. Although the maximum stress of the O - shaped ring with the larger wall thickness is smaller, but its compressibility is poor, it is not conducive to sealing. After comprehensive comparison, select 0.5mm as new combination mat O shaped ring wall thickness ruler < br > Jing County, Hebei Yongchang Chemical Mining Machinery Parts Co., Ltd. the main copper pad, combination pad, nylon rods, nylon sheath, Yongchang Chemical warmly look forward to working with you to create the brilliancy together.
