Abstract
The utility model provides a metallurgical equipment high-temperature sealing ring comprising an inner layer and an outer layer, the inner layer is a packing which can stand high temperature of 350 DEG C, the outer layer is asbestos cloth which is internally knitted with copper wires or stainless steel wires, and the packing is coated in the asbestos cloth which is internally knitted with the copper wires. The sealing ring has the beneficial effect that adopting the structure that the inner part is flexible and the outer part is rigid enables the good elasticity of the packing to be effectively combined with the corrosion resistant performance of the asbestos cloth which is internally knitted with the copper wires, the sealing ring can stand the high temperature of 350 DEG C for a long time, the variation resistibility to coldness and hotness is stable, and the service life is long.
Description
Affiliated technical field
The utility model relates to a kind of seal ring, especially a kind of seal ring that uses under worst hot case.
Background technique
The seal ring that uses on the metallurgical equipment adopts rubber material mostly at present, and is easily aging under worst hot case though sealing is reliable, has a strong impact on the sealability of equipment, and working life is short.
Summary of the invention
For the seal ring that overcomes on the existing metallurgical equipment easily wears out, the deficiency that working life is short, the utility model provides a kind of seal ring that can use for a long time under worst hot case.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of high-temperature seal ring is formed by inside and outside two layers, and internal layer is resistant to elevated temperatures packing, and skin is an asbestos cloth, and packing is wrapped in the asbestos cloth.
Be woven with copper wire in the asbestos cloth, perhaps be woven with Stainless Steel Wire in the asbestos cloth.
The beneficial effects of the utility model are soft outer structures just in adopting, make packing favorable elasticity and in knit the asbestos cloth of copper wire corrosion resistance organically combine, can for a long time anti-350 ℃ high temperature, cold-and-heat resistent variation stable performance, long service life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Among the figure: 1. packing; 2. asbestos cloth.
Embodiment
As shown in Figure 1, the seal ring of the large-scale conversion equipment of a kind of collecting smoke dust from coke oven, form by inside and outside two layers, internal layer is a packing 1, outer asbestos cloth 2, in being wrapped in, knits packing 1 in the asbestos cloth 2 of copper wire or Stainless Steel Wire, packing 1 can anti-350 ℃ of high temperature, and asbestos cloth is woven with copper wire for 2 li, and the corrosivity of high temperature resistant flue gas is good, cold-and-heat resistent changes stable performance, long service life.
