Abstract
Basis is practical newly discloses a kind of double spool electric EGR valve gasket structure, and sealing gasket comprises high-temperature resistant rubber coating and Stainless Sheet Steel, and the plating of Stainless Sheet Steel upper and lower surface is coated with high-temperature resistant rubber coating, and Stainless Sheet Steel forms through punching press and insulation shaping.The utility model changes tratitional technology, has made multiple tracks technique connecting shaping into, substantially increase the stability of structure by one time punching molded.High-temperature plastic coating ability exhaust gas temperature in this structure, up to 800 DEG C, through engine pedestal 720h endurance test no-failure, substantially increases working life and the stability of valve.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly relates to a kind of gasket structure of double spool electric EGR valve.
Background technique
A kind of double spool electric EGR valve structure (as Fig. 1), comprises valve body 1, spool 1, center-pole 3, spool 24, sealing gasket 5, sealed cover 6, screw 7, installs sealing gasket 5, sealed cover 6, screw 7 below valve body 1.This kind of valve is directly connected with engine breathing, and namely engine exhaust does not directly enter EGR valve through supercooler cooling, flows through EGR valve and enters engine aspirating system, exhaust gas temperature up to 700 DEG C ~ 800 DEG C, EGR valve working environment is severe especially.Under this severe working environment, by the stamping forming conventional seals pad (see Fig. 2 and Fig. 3) of Stainless Sheet Steel, be easy to be washed out by high-temp waste gas, cause gas leakage, and then make defective valve.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides the gasket structure of that a kind of brand new designs, resistant to elevated temperatures double spool electric EGR valve, improves working life and the stability of EGR valve.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of double spool electric EGR valve gasket structure, sealing gasket comprises high-temperature resistant rubber coating and Stainless Sheet Steel, and the plating of Stainless Sheet Steel upper and lower surface is coated with high-temperature resistant rubber coating.
Owing to have employed above technological scheme, acquired by the utility model, technological progress is as follows:
The utility model changes tratitional technology, has made multiple tracks technique connecting shaping into, substantially increase the stability of structure by one time punching molded.High-temperature plastic coating ability exhaust gas temperature in this structure, up to 800 DEG C, through engine pedestal 720h endurance test no-failure, substantially increases working life and the stability of valve.

In figure: 1-valve body, 2-spool one, 3-center-pole, 4-spool two, 5-sealing gasket, 6-sealed cover, 7-screw, 8-power and driving mechanism, 9-high-temp glue coating, 10-Stainless Sheet Steel.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Be illustrated in figure 4 the structural representation of the utility model double spool electric EGR valve sealing gasket, sealing gasket 5 comprises high-temp glue coating 9 and Stainless Sheet Steel 10.First, Stainless Sheet Steel 10, through Multi-step forming shaping, is assembled into required form, is then coated with thermostable fluorine rubber coating 9 in the upper and lower surface plating of mating face, makes finished product through series of process is shaping.As Fig. 4, Fig. 5.
Sealing gasket of the present utility model on stainless steel lower surface plating is coated with super heated rubber coating, and resistance to exhaust gas temperature, up to 800 DEG C, substantially increases working life and the stability of EGR valve.
