Abstract
The utility model belongs to aviation airborne equipment field, and in particular to a kind of heat-resisting bellows modular construction, and guide shell is set on bellows, and filled with coagulation glue.
Description
Technical field
The utility model belongs to aviation airborne equipment field, and in particular to a kind of heat-resisting bellows modular construction.
Background technology
For required corrugated expanding metal joint in each pipe-line system of aircraft, usually require that with high temperature resistant and certain benefit
Repay ability, the corrugated stainless steel tubing that such current compensation device is used in more than 400 DEG C of environment temperature the strength of materials range of decrease compared with
Greatly, the performance and used life of compensation device is had a strong impact on.Traditional corrugated expanding metal joint is applied on high temperature conduit, mainly
It is faced with high-temperature gas directly to contact with bellows, bellows temperature is raised rapidly and close to gas temperature, is caused ripple
Manage pressure-resistant performance and used life reduction so that traditional corrugated expanding metal joint service life can not increase with the aircraft same longevity
The maintenance of aircraft and maintenance cost.In addition, traditional corrugated expanding metal joint is at present when high temperature resistant is designed mainly by material
High temperature alloy is replaced by by stainless steel, production cost is easily caused and is substantially increased, economy is poor.
The content of the invention
Goal of the invention：In order to overcome the problem of prior art stainless steel metal expansion bellow high-temperature behavior is weak, this reality
A kind of heat-resisting bellows modular construction is provided with new, the ability that bellows adapts to hot environment can be effectively improved, reduction
Influence of the high temperature to material, improves the life-span, reduces production cost.
Technical scheme：A kind of heat-resisting bellows modular construction, including female fitting 1, the slip cap that is assemblied in female fitting 1
2, bellows 3 is welded on slip cap 2, convex joint 6 and bellows-welding, in slip cap 2 built with guide shell 5, in guide shell 5
Coagulation glue 4 is filled between bellows 3.
The coagulation glue 4 is high-temperature resistant rubber compound, specifically HM301 room temperature vulcanizations high temperature-resistant organic silicon sealant.
Beneficial effect：The utility model improves the ability that bellows adapts to hot environment, and economical good, technique is easy
Realization, resistant to elevated temperatures feature, it is possible to reduce the hidden danger of pipeline leakage, improve the reliability and maintainability of conduit system, therefore
Practicality is preferable, it is easy to popularization and application, with larger practical value.Can be widely applied for large aircraft, engine, space flight,
High temperature, the high-pressure conduit in the fields such as petrochemical industry, marketing have a extensive future.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Wherein, 1- female fittings, 2- slip caps, 3- bellowss, 4- elastomeric compounds, 5- guide shells, 6- convex joints.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, Fig. 1 is referred to.
As shown in figure 1, a kind of heat-resisting bellows modular construction, including female fitting 1, the slip that is assemblied in female fitting 1
Set 2, bellows 3 is welded on slip cap 2, convex joint 6 and bellows-welding, in slip cap 2 built with guide shell 5, in water conservancy diversion
Coagulation glue 4 is filled between cylinder 5 and bellows 3.
The coagulation glue 4 is high-temperature resistant rubber compound, specifically HM301 room temperature vulcanizations high temperature-resistant organic silicon sealant.It is described
Bellows interior fills elastomeric compound 4, can be effectively isolated heat transfer, and protection bellows is not subject to too high heat.In addition, water conservancy diversion
Cylinder 5 can reduce flow resistance, and avoid high temperature from directly being contacted with elastomeric compound 4.
The utility model improves the ability that bellows adapts to hot environment, and economical good, technique is easily realized, resistance to height
Warm the characteristics of, it is possible to reduce the hidden danger of pipeline leakage, improve the reliability and maintainability of conduit system, thus practicality compared with
It is good, it is easy to popularization and application, with larger practical value.It can be widely applied for large aircraft, engine, space flight, petrochemical industry
High temperature, high-pressure conduit Deng field, marketing have a extensive future.
