Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of motor EGR valve seat.
Background technique
EGR valve is one and installs and be used for the electromechanical integrated product of the amount of exhaust gas recirculation controlling to feed back to gas handling system on the engine.It is usually located at the right side of intake manifold, near throttle body, has a short metal tube leading to gas exhaust manifold to be connected with it.Its effect controls the exhausted air quantity entering intake manifold, makes a certain amount of waste gas flow into intake manifold and carry out recirculation.EGR valve is parts very important, crucial in Exhaust gas recirculation device.Because ERG valve seat need be connected with tracheae, can produce vibrations in the running of motor, so need ensure its steadiness and working life, ERG valve arrangement is in the market complicated, and installation is inconvenient and cost is higher.
Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of motor EGR valve seat, achieving the improvement to EGR valve stand structure, its structure is simple, long service life.
A kind of motor EGR valve seat that the utility model proposes, comprise valve body and connecting body, valve body is connected with connecting body, venting cavity is through to be arranged on valve body and connecting body, be parallel to venting cavity length direction, two sides of connecting body are cambered surface, connecting body increases near valve body side gradually to away from valve body side sectional area, the sidewall that valve body is parallel to venting cavity length direction is provided with fitting seat, above-mentioned fitting seat is provided with two mounting holes and two vents be communicated with venting cavity, mounting hole is arranged on the fitting seat both sides vertical with venting cavity length direction, vent is arranged on the fitting seat both sides parallel with venting cavity length direction, be provided with two between mounting hole and vent and strengthen isolation platform, the side strengthening isolation platform is cambered surface.
Preferably, fitting seat is rhombus or square.
Preferably, the line of centres of two vents and the line of centres of two mounting holes mutually vertical.
Preferably, valve seat is one-body molded of powder metallurgy.
Motor in the utility model EGR valve seat, by arranging two vents be communicated with venting cavity, can strengthen the uniformity of ventilation, by improving the structure of connecting body, adds the fastness of connecting body, and improves its stability; Strengthen the setting of isolation platform, structural strength and the steadiness of fitting seat can be improved on the one hand, can decay to the conduction of power on the other hand, and reduce the vibration amplitude of fitting seat, meanwhile, cambered surface design is carried out in the side strengthening isolation platform, can promote the effect strengthening isolation platform; Therefore, the utility model achieves the improvement to EGR valve stand structure, and its structure is simple, long service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of motor EGR valve seat that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the schematic diagram of a kind of motor EGR valve seat that the utility model proposes.
With reference to Fig. 1, in one embodiment, a kind of motor EGR valve seat that the utility model proposes, comprise valve body 1 and connecting body 2, valve body 1 is connected with connecting body 2, venting cavity 7 is through to be arranged on valve body 1 and connecting body 2, be parallel to venting cavity 7 length direction, two sides of connecting body 2 are cambered surface, connecting body 2 increases near valve body 1 side gradually to away from valve body 1 side sectional area, the sidewall that valve body 1 is parallel to venting cavity 7 length direction is provided with fitting seat 3, above-mentioned fitting seat 3 is provided with two mounting holes 4 and two vents 5 be communicated with venting cavity 7, mounting hole 4 is arranged on fitting seat 3 both sides vertical with venting cavity 7 length direction, vent 5 is arranged on fitting seat 3 both sides parallel with venting cavity 7 length direction, be provided with two between mounting hole 4 and vent 5 to strengthen isolating platform 6, the side strengthening isolation platform 6 is cambered surface, the line of centres of two vents 5 is mutually vertical with the line of centres of two mounting holes 4, wherein, fitting seat 3 is square, valve seat is one-body molded of powder metallurgy.
In the above-described embodiments, by arranging two vents 5 be communicated with venting cavity 7, the uniformity of ventilation can be strengthened, by improving the structure of connecting body 2, adding the fastness of connecting body 2, and improving its stability; Strengthen the setting of isolation platform 6, structural strength and the steadiness of fitting seat 3 can be improved on the one hand, can decay to the conduction of power on the other hand, and reduce the vibration amplitude of fitting seat 3, meanwhile, cambered surface design is carried out in the side strengthening isolation platform 6, can promote the effect strengthening isolation platform 6; Therefore, the utility model achieves the improvement to EGR valve stand structure, and its structure is simple, long service life.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
