Abstract
The utility model discloses a composite metal sleeve for thermocouples, comprising a first pipe body (1), wherein a second pipe body (2) is sheathed in the first pipe body (1), and the first pipe body (1) and the second pipe body (2) are in an interference fit relationship. The composite metal sleeve for thermocouples has higher high-temperature resistance and corrosion resistance integrally and can be used to prolong the service life of thermocouples.
Description
Technical field
The utility model relates to a kind of composite metal sleeve pipe, particularly relates to a kind of composite metal sleeve pipe for thermopair.
Background technology
In the prior art, the employed sleeve pipe of thermopair is generally single layer structure, the environment temperature of sleeve pipe work is 800～1300 ℃, therefore heat-resisting quantity and the corrosion resistivity of sleeve pipe are particularly important for the quality of sleeve pipe, but the performances such as the sleeve pipe of single layer structure is high temperature resistant and anticorrosive are all very poor, had a strong impact on the serviceable life of thermopair.
Therefore those skilled in the art are devoted to develop stronger thermopair composite metal sleeve pipes of a kind of heat-resisting quantity and corrosion resistivity.
The utility model content
Because the defects of prior art, technical problem to be solved in the utility model provides all stronger thermopair composite metal sleeve pipes of a kind of heat-resisting quantity and corrosion resistivity.
For achieving the above object, the utility model provides a kind of thermopair composite metal sleeve pipe, comprises the first body; Be set with the second body in described the first body; Described the first body and the second body interference fit.
Better, the second wall thickness of described the second body is 1:1～1:4 with the ratio of the first wall thickness of described the first body.
Better, the external diameter of described the first body is 1.13～1.80 with the ratio of the internal diameter of described the second body.
Better, the external diameter of described the first body is 12～25mm.
Better, the external diameter of described the first body is 16～20mm.
Better, the internal diameter of described the second body is 7～17mm.
Better, the internal diameter of described the second body is 10～13mm.
Better, the external diameter of described the first body is 18mm, wall thickness is 2.5mm; The internal diameter of described the second body is 11mm, and wall thickness is 1mm.
Better, described the first body adopts different metal materials with the second body.
The beneficial effects of the utility model are: the utility model is owing to can be combined with each other outer layer metal tube and the inner layer metal pipe of two kinds of unlike materials, make its inside and outside two-layer non-removable tight entity that becomes, therefore can utilize the continuous expansion of the metal interface blocking-up crystal boundary of two-layer unlike material body, give full play to inner and outer tubes owing to be in separately the advantage of different medium environment aspect high temperature resistant, wear-resistant, anticorrosive, sealing property, thereby the whole combination property that has improved sleeve pipe, and then the serviceable life of prolongation thermopair.
Description of drawings
Fig. 1 is the utility model---the structural representation of embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of thermopair composite metal sleeve pipe comprises being set with the second body 2, the first bodys 1 and the second body 2 interference fit in the first body 1, the first body 1.The first body 1 adopts different metal materials with the second body 2.
In the present embodiment, the outer diameter D of the first body 1 is 18mm, and wall thickness S1 is 2.5mm; The inner diameter d of the second body 2 is 13mm, and wall thickness S2 is 1mm.
In other embodiments, the ratio of the second wall thickness S2 of the second body 2 and the first wall thickness S1 of the first body 1 also can be other values between 1:1～1:4, to reach essentially identical technique effect.
In other embodiments, the ratio of the inner diameter d of the outer diameter D of the first body 1 and the second body 2 also can be other values between 1.13 ~ 1.80, to reach essentially identical technique effect.
In other embodiments, the outer diameter D of the first body 1 also can be other values between 12～25mm, and the inner diameter d of the second body 2 also can be other values between 7～17mm, to reach essentially identical technique effect.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technician comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
