Embodiment
Further understand and understanding for making structure characteristic of the present utility model and the effect reached had, cooperate detailed explanation, be described as follows in order to preferred embodiment and accompanying drawing:
As Fig. 1, shown in Figure 2, high temperature harmful gas slide bar seal arrangement described in the utility model comprises the slide bar 21 of doing three dimensional motion and the sealed member that matches.Sealed member mainly comprises sealing gland ring member 17, floating-ring seal assembly 16, sealing case assembly 10, silicane rubber plate 8, ceramic insulation cotton 9, larynx hoop (6,7), sealing gasket 20, flange assembly 1 and bracing structure assembly 12.
Sealing gland ring member 17 is made up of the module of two groups or more slide relative and compensation mutually, and by extension spring 18 sealing gland ring endoporus is close on 21 surfaces of slide bar.In the utility model preferred embodiment, sealing gland ring member 17 is made up of the module of two groups or more energy slide relative and changing of the relative positions compensation mutually, that is to say that slide bar 21 is when three dimensional motion all around, having part high temperature toxic gas leaks out, but sealing gland ring member 17 hugs on 21 surfaces of slide bar owing to having by slide relative and mutual changing of the relative positions compensation, stop of the leakage of high temperature harmful gas by the sliding pole axis surface, and can after the endoporus wearing and tearing, have automatic compensation function, thereby reach seal action.
Floating-ring seal assembly 16 acts on (inside and outside flexible moving enough spaces that all has) on the floating ring by a plurality of small coil springs 11 of self, apply axial force for again sealing gland ring member 17 by floating ring, reach between sealing gland ring member 17 planes and and sealing case assembly 10 faying surfaces between the plane sealing function.
Owing to be filled with the ceramic insulation cotton in the sealing case assembly 10, can reach effect of heat insulation.The outer surface of sealing case assembly 10 is fixed silicane rubber plate 8 by larynx hoop 6, thereby also reaches well heat insulation and seal action.Simultaneously, sealing case assembly 10 also by larynx hoop 7 sealing gland ring member 17 installing and locating in the inner chamber of sealing case 10.
Flange assembly 1 also by the planar high temperature pad, has solved the plane sealing problem between apparatus casing and the flange assembly 1 except above-mentioned effect.
Flange assembly 1 is fixed on outer surface to silicane rubber plate 8 by larynx hoop 6, and fixedly ceramic insulation cotton 9 and sealing reach the purpose that is flexible coupling between flange assembly 1 and the sealing case assembly 10 again from the leakage of the interior high temperature harmful gas of ceramic insulation cotton 9 to have played protection.
One end of bracing structure assembly 12 is fixed in sealing case assembly 10, and the other end is connected with flange assembly 1 by screw rod.Screw rod lower end nut 5 is by cotter pin 4 location, and screw rod upper end bolt is connected with pull bar 12 by packing ring 2.Bracing structure assembly 12 is owing to adopted unconventional connecting means, after special technique is handled, the sealing case assembly 10 that can connect plays the function of low-angle universal joint, make pull bar with sealing case assembly 10, and sealing gland ring member 17, the floating-ring seal assembly 16 of sealing case assembly 10 inner chambers do multidirectional motion with slide bar 21.For the ease of the dismounting of flange assembly 1, flange assembly 1 is installed on the seal arrangement body by hexagon socket cap head screw and sealing gasket 20.
Hence one can see that, high temperature harmful gas slide bar seal arrangement described in the utility model, owing to adopted the mode that is flexible coupling of sealing gland ring member with unique design structure, bracing structure assembly, sealing case, make slide bar radially or axial runout the time, all can prevent the high temperature poisonous gas leakage, and inside the sealing case assembly, be provided with the ceramic insulation cotton, have good effect of heat insulation.
In sum, it only is preferred embodiment of the present utility model, be not to be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
