Abstract
The utility model discloses a titanium alloy core body which comprises a pressure ring, a membrane, a titanium alloy shell, a seat core, a pressure chip and silicone oil, wherein the seat core is encapsulated in the titanium alloy shell with epoxy glue, the pressure chip is fixed on the seat core, the membrane and the pressure chip are correspondingly arranged and seal the silicone oil in the titanium alloy shell, and the pressure ring tightly presses the membrane in the titanium alloy shell. The main advantage of the titanium alloy core body is that the titanium alloy material is more resistant to corrosion and is applicable to special environments.
Description
Technical field
The utility model relates to a kind of titanium alloy core body.
Background technology
Adopt the steel matter of 316L during existing P C10 core body, corrosion resistivity does not have titanium alloy strong, can not be used for special environment.
The utility model content
The utility model purpose is to provide a kind of titanium alloy core body at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model titanium alloy core body, comprise pressure ring, diaphragm, titanium alloy housing, seat core, pressure chip and silicone oil, the seat core is encapsulated in the titanium alloy housing with epoxy glue, pressure chip is fixed on the core, the corresponding setting with pressure chip of diaphragm also is sealed in silicone oil in the titanium alloy housing, and pressure ring is pressed in diaphragm in the titanium alloy housing.
Described titanium alloy housing all adopts laser bonding to be connected with pressure ring, diaphragm.
Major advantage of the present utility model is exactly that titanium alloy material corrosion resistivity is stronger, is applicable in the special environment.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
As shown in Figure 1, the titanium alloy core body, comprise pressure ring 1, diaphragm 2, titanium alloy housing 3, seat core 4, pressure chip 5 and silicone oil 6, seat core 4 usefulness epoxy glues are encapsulated in the titanium alloy housing 3, pressure chip 5 is fixed on the core 4, diaphragm 2 is sealed in the titanium alloy housing 3 with pressure chip 5 corresponding settings and with silicone oil 6, and pressure ring 1 is pressed in diaphragm 2 in the titanium alloy housing 3.
Described titanium alloy housing 3 all adopts laser bonding to be connected with pressure ring 1, diaphragm 2.
The titanium alloy core body is that seat core (element 4 among the figure) is encapsulated into (element 3 among the figure) in the titanium alloy housing with epoxy glue, again with pressure ring (element 1 among the figure), diaphragm (element 2 among the figure), housing with laser bonding together.Impressed pressure is delivered on the inner silicone oil (element 6 among the figure) by diaphragm (element 2 among the figure), is delivered on the pressure chip (element 5 among the figure) by silicone oil again, and pressure chip (5) is exported the pressure signal that detection obtains from pin.Sensitive chip does not directly contact measured medium, forms tonometric structure of whole solid state.
The principal feature of this product:
1, unitized construction, seat core and housing separate, and fix with epoxy glue
2, Wai Bu pressure ring, diaphragm, housing all adopt the titanium alloy material, and be stronger than general corrosion resistance of steel, is applicable in the special environment.
PC10 core body during the immediate with it core body of the utility model, the pressure ring of titanium alloy core body, diaphragm, housing all adopts the titanium alloy material to forge, the titanium alloy core body is a core component of making pressure transducer and pressure unit, as a kind of high performance pressure-sensing device, adopt all-welded structure, the height of anti-the static pressure, stable, reliable.
The above only is a preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
