Description
Technical field
The utility model relates to a kind of high-temperature flange pad profile of tooth contact linkage structure.
Background technique
Since entering 21st century, the contradiction of the same energy supply of economic development, environmental protection, countries in the world are one after another using " safely, efficiently, environmental protection, the economy " theme as industrial development.This trend is the safe operation of high-temperature service and the tightness of connected system at petrochemical industry major embodiment.Flange joint is widely used in the joint of petrochemical industry pressure piping and pressure vessel with its easy-disassembling-assembling advantage.When being in high temperature and high pressure condition for a long time, easily there is leakage failure in flange connections.Conventional prominent face flange is convex surface platform at end face of flange, and operating mode lower flange can produce moment of flexure, pad unbalance stress, flange plate deflects, and easily leaks.In addition, under High Temperature High Pressure serviceability, end face of flange, pad and bolt all can be subject to very large stress, cause the creep of each component materials in Flange joint, cause piping flange connected system to relax, finally cause leakage failure.This kind of high-temperature flange pad pentagon contact Connecting format, based on this background, is applied to the leakage that Flanged Joints at Elevated Temperature effectively can prevent flange.
Model utility content
In order to solve the problem, the purpose of this utility model is to provide a kind of high-temperature flange pad profile of tooth to contact linkage structure, and this piping flange linkage structure can be applied to high temperature and high pressure condition, and the tightness that long-term maintenance is good.
The utility model realizes particular by following technological scheme:
A kind of high-temperature flange pad profile of tooth contact linkage structure, comprise the upper flange and lower flange that cooperatively interact, described upper flange and lower flange comprise integrated flange plate respectively, cone neck and pipeline cylinder, sealing gasket is provided with between described upper flange and lower flange, the upper sealing surface of described upper flange and the lower sealing surface of lower flange are respectively equipped with the continuous groove structure at least one section of same radius, described sealing gasket is by pad skeleton and pad skeleton, structure composition under structure and pad on pad on lower surface, described pad under structure and pad, structure is respectively equipped with the continuous protruding structure at least one section of same radius, the mutually corresponding and protruding structure of described groove structure and protruding structure coordinates and inserts in groove structure.
Further, the interval between described protruding structure is equal, and the interlaced setting of structural protruding structure under structure and pad on pad.
Further, described groove structure is pentagon groove, and described protruding structure is pentagon boss.
The beneficial effect that the utility model produces is: the utility model arranges the ripple toothed projections structure of different radii size on Expanded graphite metal wave tooth composite gland bush, multiple backlash defines multi-stage sealed, a kind of seal form of similar labyrinth seal is formed with the groove structure of flange facing, can be heat energy by the kinetic energy of interior media, potential energy as much as possible, reduce the pressure energy of interior media, slow down and even stop a leak.The utility model high-temperature flange pad pentagon tooth contact Connecting format, compared to common flange, increases effective sealing area, reduces the stress level between flange facing and gasket surface, enhance sealing effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the overall sectional structure schematic diagram of the utility model;
Fig. 2 is the structural representation of local A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 and 2, a kind of high-temperature flange pad profile of tooth contact linkage structure, comprise the upper flange 5 and lower flange 7 that cooperatively interact, described upper flange 5 and lower flange 7 comprise integrated flange plate 1 respectively, cone neck 3 and pipeline cylinder 4, sealing gasket 6 is provided with between described upper flange 5 and lower flange 7, the upper sealing surface 7 of described upper flange and the lower sealing surface 8 of lower flange are respectively equipped with the continuous groove structure 9 at least one section of same radius, described sealing gasket 6 is by pad skeleton 601 and pad skeleton 601, on pad on lower surface, under structure 602 and pad, structure 603 forms, described pad under structure 602 and pad, structure 603 is respectively equipped with the continuous protruding structure 10 at least one section of same radius, the mutually corresponding and protruding structure 10 of described groove structure 9 and protruding structure 10 coordinates and inserts in groove structure 9.
Interval between the present embodiment relief structure 10 is equal, and the interlaced setting of protruding structure 10 on pad under structure 602 and pad in structure 603, such Expanded graphite metal wave tooth composite pad has better compression recovery performance.
Groove structure 9 is pentagon groove, and described protruding structure 10 is pentagon boss.The upper sealing surface 7 of the upper flange of sealing gasket is consistent with the pentagon shape odontoid of structure 603 under structure on pad 602 and pad with the lower sealing surface 8 of lower flange, omit cone neck, simplified structure, avoid additionally arranging boss, the cone neck that protruding structure 10 carries can increase the bearing capacity to moment of flexure, improve the moment of flexure ability to bear of Flange joint, part eliminates the deflection and creep that high temperature and high pressure environment lower flange produces because of moment of flexure.Sealing gasket is Expanded graphite wave tooth spacer simultaneously, Flange joint still adopts bolt 2 to connect, it is multi-stage sealed that sealing configuration is that multiple backlash defines, and form a kind of seal form of similar labyrinth seal, can be heat energy by the kinetic energy of interior media, potential energy as much as possible, reduce the pressure energy of interior media, slow down and even stop a leak.
Gasket seal pentagon tooth contact Connecting format of the present utility model, compared to common flange, increases effective sealing area, reduces the stress level between flange facing and gasket surface, enhance sealing effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
