Body product, it is part most important, crucial in ERG.As national Abgasgesetz is more and more stricter, bivalve
Core EGR valve is with its good airproof performance, leakage rate is few and service life is grown, and obtains the extensive use of in the market.
The assembling structure of conventional double spool EGR valve is to load valve body assembly after being press-fitted, pressed with center-pole using small valve core,
Then the technique of big valve core is welded again, it is necessary to which three process, assembling is complicated, not only increases labour cost, while reduce again
Operating efficiency, in current keen competition environment, urgent need reduces cost, improves production efficiency and ensures product quality to improve
The competitiveness of enterprise.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of assembling structure of double spool and center-pole, solves dress at present
With aspect technique is complicated, cost is high, ineffective problem, so as to improve the quality of electric EGR valve.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of valve element assembling structure of double spool EGR valve, including the center-pole inside valve body assembly is inserted into, center-pole
Middle and lower part is fixedly installed the small valve core and big valve core being engaged with valve base sealing mouth respectively, the center-pole and small valve core and greatly
It is fixedly connected between valve element by welding manner；The small valve core is identical with big valve core structure, is round table-like valve core structure, circle
The top end face diameter of mesa-shaped valve element is less than the diameter of valve seal mouth, and the bottom face diameter of round table-like valve element is more than valve seal mouth
Diameter；The driving plate of cam structure is provided with the valve seat above center-pole, one end of driving plate passes through rotating shaft and EGR
The motor axis connection of valve, the other end and the center-pole apical grafting of driving plate.
A kind of valve core structure of above-mentioned double spool EGR valve, the list along actuated by cams edges of boards edge is offered in the driving plate
It is provided with and is slidably matched in stopper slot for spacing to driving plate progress by straight pin to opening stopper slot, on the valve seat
Bearing.
A kind of valve core structure of above-mentioned double spool EGR valve, the center-pole are stepped construction, and small valve core is fitted in center
At the ladder of bar；The center-pole is mutually equipped with place's diameter with small valve core and is more than center-pole and big valve core mutually equipped place's diameter.
It is as follows as a result of above technical scheme, the invention technological progress.
Small valve core and big valve core of the present invention use assemble welding technique with center-pole assembling, have both reduced original double spool
EGR valve assembly technology difficulty, simplifies technique, while reduces the production cost of double spool EGR valve again, improves double spool
