Abstract
The invention discloses a protective device for an electric exhaust gas recirculation (EGR) valve. The protective device comprises a body matched with a linear sensor shell of the electric EGR valve; the top of the body is provided with a top cover used for protecting the side wall of the linear sensor shell; and the top cover is fixedly connected with a handle perpendicular to the top cover. The protective device is simple in structure and low in cost, and is applied to the electric EGR valve to protect a linear sensor, can ensure that the electric EGR valve is not damaged or deformed in the transportation process, and effectively solves the problem that the valve fails caused by failure of the linear sensor.
Description
Technical field
The present invention relates to a kind of protective gear in a kind of engine exhaust emission recirculating system, particularly a kind of for the device of electronic EGR valve being protected in transportation process.
Background technique
The EGR valve is mainly used in regulating the flow of control EGR gas in engine exhaust-gas recirculating system (egr system), electronic EGR valve is by the aperture size of inside DC MOTOR CONTROL suction port in the morning, thereby adjusting exhaust gas flow, return cylinder after making waste gas and fresh air mixing by a certain percentage and carry out recirculation, with reduction combustor inner cylinder temperature and velocity of combustion, thereby further reduce NO
XDischarge amount.For pneumatic EGR valve, electronic EGR valve has the advantages that speed of response is fast, operation is more stable, and electronic EGR valve can also solve the difficult problem that some vehicle does not have vacuum source, therefore uses comparatively extensive.
At present, on the market at the electronic EGR valve of usefulness, generally need rotatablely moving of motor is converted into the straight line motion of valve switch, in the conversion process of the two motion, there is an actuator to play crucial effects, that is exactly linear transducer, and linear transducer is installed on the valve body of electronic EGR valve usually.Because employed linear transducer all is to adopt the working of plastics Shooting Technique in the market, this technology cost is low, simple in structure, versatility is good, therefore is extensive use of on the industry.But this linear transducer is owing to be plastic product, its fragility is big, in use and will damage a little because of carelessness in the packed and transported process and cause whole EGR defective valve unavailable, adding its inside has contact pin, is subjected to ectocine bending deflection to cause valve to use.
Summary of the invention
The technical problem that the present invention solves provide a kind of simple in structure, be used for the device that can effectively shield to electronic EGR valve in transportation process.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Electronic EGR valve protection device comprises and the linear transducer shell of electronic EGR valve equipped body mutually that the top of body is provided with the top cover for the protection of the linear transducer side wall of outer shell, is fixedly connected with the handle perpendicular to top cover on the described top cover.
The concrete structure of described handle is: described handle is plate armature, and the outer end of handle is provided with the manhole of being convenient to hand.
The improvement of described handle is: the outer end that described handle is provided with manhole is set to arc-shaped structure.
Improvement of the present invention is: be arranged with the stiffening rib of some projectioies on the peripheral wall of described body in parallel, described stiffening rib is both to the chamber body projection, also to the body outer lug.
Further improvement of the present invention is: described body, top cover, handle and stiffening rib adopt the plastics once-through.
Owing to adopted above technological scheme, the invention technological progress is:
The present invention is simple in structure, with low cost, is applied on the electronic EGR valve linear transducer is protected, and can guarantee that electronic EGR valve is not destroyed in transportation process and is out of shape, and efficiently solves the defective valve problem that causes because of the linear transducer fault.The present invention adopts common plastics to make, and in conjunction with its structure, makes the present invention have better elastic, and telescopicing performance is good, promotes gently during insertion to get final product; The setting of handle is convenient to the operating personnel and easily the present invention is extracted.Three that arrange on the body outer peripheral surface of the present invention protrude stiffening rib, can make that the present invention's elasticity in assembly process is suitable, can guarantee effectively to cooperate with linear transducer, can not come off naturally again.

Fig. 2 is the use phase diagram on the present invention the is applied in electronic EGR valve.
Wherein: 1. body, 2. top cover, 3. handle, 4. stiffening rib; A. electronic EGR valve, B. linear transducer, C. the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.
A kind of electronic EGR valve protection device, its structure as shown in Figure 1.Comprise body 1, top cover 2 and handle 3.Body 1 is equipped mutually with the linear transducer B shell of electronic EGR valve A, and top cover 2 is fixedly connected on the top of body, for the protection of the linear transducer side wall of outer shell; Handle 3 arranges perpendicular to top cover 2, and is fixedly connected on the top cover 2.
Be arranged with the stiffening rib 4 of some projectioies on the peripheral wall of body in parallel, stiffening rib is both to the chamber body projection, also to the body outer lug, with guarantee the present invention with the linear transducer assembly process in elasticity.
Handle 3 is used for when electronic EGR valve assembles the present invention being taken off from linear transducer.Handle adopts plate armature in the present embodiment, so that reliable connection the between handle and the top cover avoided making the present invention reusable because local pressure damages top cover.The outer end of handle is provided with the manhole of being convenient to hand, and the outer end that handle is provided with manhole is set to arc-shaped structure, and both the convenient working personnel exerted oneself after finger is passed through hole, can not accidentally injure the operating personnel again.
In the present embodiment, the body of protective gear, top cover, handle and stiffening rib adopt plastic production, and processing technology adopts common injection moulding process once-through, and is durable.
