Abstract
The utility model discloses an electric EGR valve for preventing waste gas from entering into a sensor, which comprises a valve body, a power output shaft, a bearing, a sensor sliding rod, a central rod, a sliding block arranged on the top end of the central rod, a valve core positioned at the bottom end of the central rod, and a copper sleeve sheathed on the central rod, wherein a spring is arranged above the copper sleeve sheathed on the central rod; a sealing skin film is sheathed above the copper sleeve on the central rod; the lower end surface of a flange of the skin film clings to the valve body, and an inner cavity of the skin film is closely matched with the central rod; a check block is sheathed above the skin film on the central rod and is closely matched with the central rod; the upper end surface of the skin film is closely pressed by the end surface of the check block; the spring is pressed on the upper end surface of the flange of the skin film; and the skin film is made of high-temperature-resistant silicon rubber. The central rod and the valve body of the electric EGR valve are arranged into the skin film made of the high-temperature-resistant silicon rubber, the skin film is fixed on the central rod by the check block at the upper end of the skin film, and the lower end of the skin film is pressed by the spring, so that an effective sealing cavity is formed between the central rod and the valve body, the waste gas is prevented from being leaked between the copper sleeve and the central rod and entering into the sensor, and the reliability of other transmission mechanisms can be effectively improved; furthermore, the electric EGR valve solves the sensor fault caused by the waste gas entering into the sensor.
Description
Technical field
The utility model relates to the valve in a kind of automobile engine tail gas discharging waste gas recirculating system, also is the valve in the egr system, belongs to engine exhaust emission control gear technical field.
Background technique
The EGR valve plays the EGR gas flow and regulates control action in vehicle engine exhaust gas recirculation system.The major function of EGR valve is the size that changes magnetic force by the electric current of the vacuum electromagnetic regulator coil that changes control EGR degree of vacuum, reaches different degree of vacuum, impels EGR valve suction port switch size, thereby regulates exhaust gas flow.
Because sensor is contained in the top of center-pole in the present electronic EGR valve, gapped between center-pole and the copper sheathing, cause valve in use waste gas from the gap of center-pole and copper sheathing, leak, final waste gas enters the inside of sensor by the slide bar of sensor, can cause the sensor clamping stagnation after the long-time use of valve, and lose efficacy.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can prevent that waste gas from entering sensor, makes sensor can not enter waste gas and causes the electronic EGR valve of sensor failure.
The technical solution of the utility model is:
A kind of waste gas that prevents enters the electronic EGR valve of sensor, the copper sheathing that comprises suit on spool that the bottom of slide block that the top of valve body, pto, bearing, sensor slide bar, center-pole, center-pole is provided with, center-pole is provided with, the center-pole, the copper sheathing of suit top is provided with spring on the center-pole, the top of copper sheathing is set with the sealing epithelium on the center-pole, the flange lower end surface of epithelium is adjacent to valve body, the inner chamber of epithelium and center-pole drive fit.
The top suit block of center-pole epithelial membrane, block and center-pole drive fit, the end face of block compresses the upper-end surface of epithelium.
Spring compression is on the flange upper-end surface of epithelium; The material of epithelium is resistant to elevated temperatures silicone rubber.
Beneficial effect: the utility model with the center-pole of electronic EGR valve and valve body pack into one can be high temperature resistant the epithelium of silicone rubber, the epithelium upper end is fixed on epithelium on the center-pole with block, the spring compression epithelium is then used in the lower end, so just an effective seal chamber will have been formed between center-pole and the valve body, prevent that waste gas from leaking between copper sheathing and center-pole, and enter sensor, also can effectively increase the reliability of other driving mechanism; Solve waste gas and entered the fault that sensor causes sensor failure.
Description of drawings
Fig. 1 is the structural drawing before electronic EGR valve of the present utility model improves;
Fig. 2 is the structural drawing after electronic EGR valve of the present utility model improves;
Fig. 3 is the utility model ring structure figure.
Among the figure: 1-sensor slide bar, 2-slide block, 3-bearing, 4-pto, 5-spring, 6-block, 7-epithelium, 8-valve body, 9-copper sheathing, 10-center-pole, 11-spool.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of waste gas that prevents enters the electronic EGR valve of sensor, the copper sheathing 9 that comprises suit on spool 11 that the bottom of slide block 2 that the top of valve body 8, pto 4, bearing 3, sensor slide bar 1, center-pole 10, center-pole 10 is provided with, center-pole 10 is provided with, the center-pole 10, copper sheathing 9 tops of suit are provided with spring 5 on the center-pole 10, the top of copper sheathing 9 is set with sealing epithelium 7 on the center-pole 10, the flange lower end surface of epithelium 7 is adjacent to valve body 8, the inner chamber of epithelium 7 and center-pole 10 drive fits.
The top suit block 6 of center-pole 10 epithelial membrane 7, block 6 and center-pole 10 drive fits, the end face of block 6 compresses the upper-end surface of epithelium 7.
Described spring 5 is pressed on the flange upper-end surface of epithelium 7.The material of epithelium 7 is resistant to elevated temperatures silicone rubber.
When electronic EGR valve is worked, export running torques by the power output by pto 4, and running torque is delivered on the bearing 3 by oscillating arm mechanisms, bearing 3 forces slide block 2 to move up and down in 2 li rollings of slide block, because center-pole 10 links together with slide block 2, and center-pole 10 presses with spool 11 and links together, therefore waste gas flows along with the unlatching of spool 11, waste gas can enter in the sensor of valve by copper sheathing 9 and center-pole 10 after spool is opened, and the utility model has increased the structure of epithelium 7, prevented that waste gas from entering sensor internal, solved sensor causes sensor failure because of waste gas enters problem.
