Description
Technical Field
The utility model relates to a last part of automobile exhaust gas circulation system, concretely relates to automatically controlled circulating valve of exhaust gas.
Background
The exhaust gas recirculation valve for automobile utilizes vacuum negative pressure working principle, and is mainly applied to the tail gas discharge system of automobile engine, under the high-temperature running state of automobile engine cylinder body, it is easy to produce inert gas, such as nitrogen oxide NOX, so that the discharge can not reach the standard, and is not environment-friendly.
Because these waste gases all exist for high temperature, if can make the engine temperature too high when through exhaust gas circulation valve not cool down, increase the production of exhaust gas carbon oxide, consequently must cool down through the cooling box for waste gas, all can dispose the exhaust gas circulation valve on the cooling box, the inlet of waste gas circulation valve gets into and cools down through the cooling box, and the gas outlet of follow exhaust gas circulation valve is discharged again.
And the flow control on the existing exhaust gas circulating valve is unstable, so that the ECU can not well control the entering amount of the exhaust gas when the EGR system is opened, and the exhaust gas can not be effectively treated.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide an electrically controlled circulation valve for exhaust gas, which has stable flow control and reliable structure.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an automatically controlled circulating valve of exhaust gas, includes socket, motor, valve body, valve rod and valve block, the valve block installation the tip of valve rod, valve body below be equipped with the valve port, the valve block setting be in the valve port position, be equipped with the circuit board in the socket, this circuit board with motor electrically conductive connection, the rotating member has in the motor, the valve body in be equipped with the telescopic link, the shaft hole spiro union of this telescopic link and rotating member the valve body in still be equipped with the return mechanism that the valve rod is connected makes through this return mechanism the tip of telescopic link with the valve rod tip contacts.
The return mechanism is including setting up return chamber in the valve body the return intracavity be equipped with fender flange and return spring, the fender flange fix the tip of valve rod, return spring one end butt is in keep off on the flange, the other end with return intracavity wall contacts.
The rotating piece is made of plastic.
The valve body in be equipped with the positioning disk, the positioning disk middle part be equipped with the guiding hole, the telescopic link alternate in the guiding hole.
The valve body in be equipped with the guide pin bushing that the valve rod corresponds, the valve rod passes from the guide pin bushing hole, be equipped with annular oil storage tank on the inner wall of guide pin bushing.
The utility model discloses a this kind of structure, the rotating member through the motor rotates and drives the telescopic link flexible to drive the valve block on the valve rod and open the valve port, because the rotating member passes through the threaded connection transmission with the telescopic link, make the stroke control of valve rod more accurate stable, the valve rod blocks up the valve port through return mechanism self return simultaneously, makes the structure more reliable, has just so realized the stable and reliable technological effect of structure of flow control.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
FIG. 1 is a block diagram of an embodiment of the present invention;
fig. 2 is an enlarged view of a in fig. 1.
Detailed Description
The present invention will be specifically described below by way of examples.
As shown in fig. 1, the embodiment discloses an exhaust gas electric control circulating valve, which comprises a socket 1, a motor 2, a valve body 3, a valve rod 4 and a valve plate 5, wherein the valve plate 5 is provided with an end portion of the valve rod 4, a valve port 6 is arranged below the valve body 3, the valve plate 5 is arranged at the position of the valve port 6, a circuit board 7 is arranged in the socket 1, the circuit board 7 is electrically connected with the motor 2, a rotating member 21 is arranged in the motor 2, an expansion link 30 is arranged in the valve body 3, the expansion link 30 is in threaded connection with a shaft hole of the rotating member 21, a return mechanism 8 connected with the valve rod 4 is further arranged in the valve body 3, and the end portion.
The return mechanism 8 comprises a return cavity 81 arranged in the valve body 3, a blocking disc 82 and a return spring 83 are arranged in the return cavity 81, the blocking disc 82 is fixed at the end part of the valve rod 4, one end of the return spring 83 abuts against the blocking disc 82, and the other end of the return spring is in contact with the inner wall of the return cavity 81. The valve plate 5 on the valve rod 4 can automatically block the valve port 6 under the action of the return mechanism 8, so that the motor 2 saves more electricity and has more reliable and stable structure.
The motor 2 comprises a winding 23 and a rotary magnetic pole 22, an inner hole matched with the rotary piece 21 is formed in the rotary magnetic pole 22, the rotary piece 21 is fixed in the inner hole, and meanwhile, the rotary piece 21 is made of a plastic material, so that the processing is more convenient, the electric leakage is avoided, and the transmission is more safe and reliable.
Be equipped with positioning disk 9 in the valve body 3, positioning disk 9 middle part is equipped with guiding hole 91, and telescopic link 30 alternates in guiding hole 91. By adopting the structure, the telescopic rod 30 can be more stably stretched, and the transmission reliability is ensured.
Specifically, as shown in fig. 2, a guide sleeve 10 corresponding to the valve rod 4 is arranged in the valve body 3, the valve rod 4 passes through an inner hole of the guide sleeve 10, and an annular oil storage tank 101 is arranged on the inner wall of the guide sleeve 10. The lubricating oil in the oil storage tank 101 can make the up-and-down movement of the valve rod 4 smoother, and the structural reliability is further improved.
Adopt above-mentioned technical scheme, rotating member 21 through motor 2 rotates and drives telescopic link 30 flexible to valve block 5 on the drive valve rod 4 opens valve port 6, because rotating member 21 passes through the threaded connection transmission with telescopic link 30, makes the stroke control of valve rod 4 more accurate stable, and valve rod 4 blocks up valve port 6 through return mechanism 8 self return simultaneously, makes the structure more reliable, has just so realized the stable and reliable technological effect of structure of flow control.
