Abstract
The utility model discloses an adapter is sealed to high life, adapter is sealed to high life constitutes as follows: switching needle (1), glass pearl (2) and stainless steel mounting panel (3), with stainless steel mounting panel (3) sealing -in after glass pearl (2) melting, glass pearl (2) after the melting are less than stainless steel mounting panel (3) apparent height, the thermal expansion coefficient looks recency of glass pearl (2) and stainless steel mounting panel (3) is not less than 90%. Adapter is sealed to high life operating temperature is - 55 DEG C -+ 85 DEG C, in the medium -term and long -term use of jet fuel. Possess characteristics such as better mechanical strength, leakproofness, high temperature resistance and electrical property, become the highly reliable sealed adapter that uses under high pressure, high mechanical stress and the high temperature stress occasion. And is provided with high economic value and social value.
Description
Technical field
The utility model relates to structural design and the applied technical field of adapter, specifically provides a kind of high life sealing adaptor device.
Background technology
Traditional adapter Total Product adopts glass sintering technique, by high temperature, glass, switching pin and housing is fired into one, can reaches excellent sealing effect.But its shortcoming clearly: first, adopt glass sintering technique, replace insulator with the glass cake after sintering, all switching pins are fixed on a large glass cake, glass cake is frangible, very easily occurs broken limit, the phenomenon that loses flesh, even occurs crackle under stronger vibration environment.Secondly, sintering process adopts the process of first burning and plating afterwards substantially, causes switching crown portion coating deficiency or switching crown portion not to plate coating because there being glass chamfering in electroplating process.Make switching crown portion that corrosion occur, cause broken needle phenomenon.
People urgently wish to obtain the excellent high life sealing adaptor device of a kind of technique effect.
Utility model content
Order of the present utility model is to provide a kind of high life sealing adaptor device, possesses the features such as good mechanical strength, sealing, heat-resisting quantity and electrical property, the highly reliable sealing adaptor device used under becoming high pressure, high mechanical stress and high-temperature stress occasion.
Described high life sealing adaptor device is constructed as follows: switching pin 1, bead 2 and stainless steel mounting panel 3; With stainless steel mounting panel 3 sealing-in after bead 2 melting, bead 2 after melting is lower than stainless steel mounting panel 3 apparent height, the similar thermal expansion coefficient degree of described bead 2 and stainless steel mounting panel 3 is not less than 90%, minimizes with the internal stress reaching closure.The polishing of stainless steel mounting panel 3 surface electrical, switching pin 1 arranged outside has Gold plated Layer, and switching pin 1 is connected with stainless steel mounting panel 3 by the bead 2 after melting.
Described switching pin 1, bead 2 and stainless steel mounting panel 3 junction are sealed by casting glue 4.Casting glue is consistent with stainless steel mounting panel 3 apparent height.Greatly improve the phenomenon that broken needle appears in sintered products.
Described stainless steel mounting panel 3 is provided with seal groove.The sealing property of further reinforcement product.
Stainless steel mounting panel 3 substitutes traditional large glass cake, and greatly strengthen the durability of product, described corrosion resistant plate is specially 1Cr18Ni9Ti corrosion resistant plate.
High life sealing adaptor device product entirety adopts glass sintering technique, by high temperature, glass, switching pin and mounting panel is fired into one, can reaches excellent sealing effect.
The process of the root after described high life sealing adaptor device contact sintering is design focal point.Former sintered products coating again after need sintering, causes the glass chamfering that the not enough or contact root of contact root coating occurs.Easily there is corrosion in contact root, causes broken needle.Affect product useful life.The patented product newly designs contact root structure, and after sintering, glass cake is lower than mounting panel surface, with the embedding of J106 glue, ensures encapsulating place not higher than mounting panel surface.Efficient solution resolution pin phenomenon.
Described high life sealing adaptor device working temperature is-55 DEG C ~+85 DEG C, uses for a long time in jet fuel.Possess the features such as good mechanical strength, sealing, heat-resisting quantity and electrical property, the highly reliable sealing adaptor device used under becoming high pressure, high mechanical stress and high-temperature stress occasion.There is comparatively huge economic worth and social value.
