Abstract
The invention discloses a plug-in type electric EGR valve base protection device. The plug-in type electric EGR valve base protection device comprises a plastic sleeve, wherein the outer circumferential side of a valve base is annularly sleeved with the plastic sleeve, and the plastic sleeve and the valve base are coaxially arranged. A clamping buckle assembled at the bottom of the valve base is arranged at the bottom of the inner end face of the plastic sleeve, and the diameter of the clamping buckle is larger than that of the upper middle portion of the inner end face of the plastic sleeve. Frictional anti-slide ribs are evenly distributed on the outer circumferential face of the plastic sleeve. Through the application of the plug-in type electric EGR valve base protection device, the valve base cannot be damaged or deformed in the production assembly process and the packaging and transporting process till being installed on an engine, a guarantee is provided for high precision of match between the valve base and the air inlet side of the engine, and valve failure is effectively prevented.
Description
Technical field
The present invention relates to engine exhaust emission control gear technical field, particularly the valve seat protective gear of the electronic EGR valve of a kind of plug-in type.
Background technique
EGR valve plays the executive component effect that regulates EGR gas flow in engine exhaust-gas recirculating system.At present, on market, can be divided into integrated type and two kinds of structures of plug-in type at the electric EGR valve of use, wherein the electronic EGR valve of that plug-in type is widely used on motor because it is easy for installation, volume is little, cost is low.
As shown in Figure 1; the electronic EGR valve of plug-in type is equipped with by valve seat and motor; while easily making the electronic EGR valve of plug-in type install, often there will be gas leak phenomenon on motor, thereby cause motor often to there will be in the course of the work the run helter-skelter generation of phenomenon of waste gas.The main cause that causes above-mentioned phenomenon is relevant with engine charge side installation quality of fit with the valve seat of electric EGR valve, this has just proposed the requirement of two aspects to working process, the machining precision of first valve seat and engine charge side, it two is quality of fits of valve seat and engine charge side.For the machining precision of valve seat and engine charge side, control than being easier to; But for the quality of fit of valve seat and engine charge side, because the valve seat of the electronic EGR valve of existing plug-in type is all aluminum material, there is the soft feature of matter, collide with a little a little and just there will be damage phenomenon, thus cause motor and electric EGR valve poorly sealed close and occur that the problem of gas blowby gas leakage occurs.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of valve seat protective gear being applied on the electronic EGR valve of plug-in type is provided, poorly sealed close and occur the problem of gas blowby gas leakage in order to solve motor and electric EGR valve.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
The electronic EGR valve base of a kind of plug-in type protective gear, comprises and is located on valve seat outer circumferential sides the plasticity sleeve with the coaxial setting of valve seat; Described plasticity sleeve interior edge face bottom is provided with and the match buckle of dress of valve seat bottom, and the diameter of buckle is greater than the diameter of plasticity sleeve interior edge face middle and upper part; The even anti-skidding muscle of friction that is furnished with on the outer peripheral surface of described plasticity sleeve.
The electronic EGR valve base of a kind of plug-in type protective gear, its improvement is: described plasticity sleeve adopts common injection moulding process to make by nitrile butadiene rubber.
Owing to having adopted above technological scheme, the invention technological progress is as follows.
The present invention makes valve seat produce assembling and packed and transported process until the distortion that is not destroyed before installing to motor, give security for the high quality of fit between valve seat and engine charge side, further prevented the defective valve phenomenon producing because of valve seat and motor matching problem.The present invention adopts common injection moulding process to make by common plastic materials nitrile butadiene rubber, and processing cost is low; In addition, the softness of the simple structure and material of the present invention self makes it have good stretchability, one pushes away gently the human oriented design of the anti-skidding muscle structure that rubs on plasticity sleeve outer peripheral surface when insertion, have gentle hands light one is drawn and can easily be extracted from valve, and assembling unloading is very convenient; The design of plasticity sleeve interior edge face bottom bayonet structure, can ensure can not come off after the present invention is assemblied on valve seat.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the structural representation after the electronic EGR valve assembling of the present invention and plug-in type.
Wherein: 1. valve seat, 2. plasticity sleeve, 3. friction anti-skidding muscle, 4. buckle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
The electronic EGR valve base of a kind of plug-in type protective gear, its structure as shown in Figure 1, mainly comprises the plasticity sleeve 1 being located on valve seat, plasticity sleeve 1 coaxially arranges with valve seat.The bottom of plasticity sleeve interior edge face is provided with buckle 4, and the bottom of buckle and valve seat is equipped mutually, and the diameter of buckle 4 is greater than the diameter of plasticity sleeve interior edge face middle and upper part, can not drop ensureing after the electronic EGR valve base of the present invention and plug-in type has assembled.On the outer peripheral surface of plasticity sleeve of the present invention also even be furnished with friction anti-skidding muscle 3.
In the present embodiment, plasticity sleeve adopts common injection moulding process to make by nitrile butadiene rubber.
The present invention, when with the electronic EGR valve base assembling of plug-in type, because plasticity sleeve self has stretchability, therefore one draws to the electronic EGR valve of plug-in type direction with hand gently, just can be sleeved on easily on the excircle of valve seat.
Claims (2)
1. the electronic EGR valve base of a plug-in type protective gear, is characterized in that: comprise and be located on valve seat (1) outer circumferential sides the plasticity sleeve (2) with the coaxial setting of valve seat; Described plasticity sleeve interior edge face bottom is provided with and the match buckle (4) of dress of valve seat bottom, and the diameter of buckle (4) is greater than the diameter of plasticity sleeve interior edge face middle and upper part; The even anti-skidding muscle of friction (3) that is furnished with on the outer peripheral surface of described plasticity sleeve.
