Abstract
The utility model relates to a noise silencing extinguisher for a motor vehicle. The noise silencing extinguisher for a motor vehicle has a good spark blocking effect, and can effectively lower noise. The noise silencing extinguisher for a motor vehicle has the technical proposal that the noise silencing extinguisher for a motor vehicle is provided with a shell body. The shell body is provided with an air inlet hole and an air outlet hole. A butterfly valve is arranged in the shell body. The butterfly valve is composed of two valve sheets. The two valve sheets and a center roraty shaft are fixed. The noise silencing extinguisher for a motor vehicle is characterized in that the two valve sheets are provided with trapezoid holes in a stagger mode. Block tongues which can cause automobile tail gas to generate spiral motion are arranged on the positions of the trapezoid holes. The block tongues are extended into a valve cavity. Due to the fact that trapezoid guide holes are adopted by the noise silencing extinguisher for a motor vehicle, the blocking tongues are arranged on the positions of the trapezoid holes, spiral air current can be effectively generated, and therefore, the noise silencing extinguisher for a motor vehicle has good effects of spark blocking and noise reduction.
Description
Technical field: the utility model relates to a kind of automobile-use noise reduction shorting-out device.
Background technique: with the immediate prior art of the utility model be that the patent No. is 96248439.3 patents, what the valve block of this patent adopted is meniscate pilot hole, and the rotating shaft external handle.The shortcoming of this kind structure is that the crescent shape pilot hole can not effectively produce spiral air flow, makes to stop that the effect of Mars is not ideal enough, and there have the rotating shaft external handle to take up space again to be bigger, and it is convenient inadequately to use.
The model utility content: it is effective that the technical problems to be solved in the utility model provides a kind of Mars that stops, and the effective automobile-use noise reduction shorting-out device of noise reduction.Technological scheme:, a kind of automobile-use noise reduction shorting-out device, has housing, housing has inlet hole, air outlet hole, be provided with fly valve in the housing, fly valve is made of two valve blocks, and two valve blocks and central rotating shaft are fixed, and it is characterized in that: two valve blocks are staggeredly equipped with trapezoidal hole, the trapezoidal hole place is provided with and can makes vehicle exhaust produce the retaining tongue of spiral motion, and the retaining tongue stretches in the valve pocket.Beneficial effect:, can effectively produce spiral air flow, so stop the effective of Mars and noise reduction because the utility model adopts trapezoidal pilot hole, and is provided with the retaining tongue at the trapezoidal hole place.Have, side joint knob outside rotating shaft makes very convenient to use again.The utility model is better than prior art, is diverse technological scheme.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of valve block.
Embodiment: as shown in Figure 1, housing 1 has inlet hole 2, air outlet hole 3, be provided with fly valve in the housing, fly valve is made of two valve blocks 4, two valve blocks and central rotating shaft 5 are fixing, and as shown in Figure 1 and Figure 2, two valve blocks are staggeredly equipped with trapezoidal hole 6, the trapezoidal hole place is provided with and can makes vehicle exhaust produce the retaining tongue 7 of spiral motion, and the retaining tongue stretches in the valve pocket.During enforcement, hull outside is provided with knob 8, and knob and central rotating shaft are fixed, and retaining tongue and valve block are the 10-15 degree, is 13 degree in the present embodiment.
During work, product is installed in motor exhaust discharges on the mouth of pipe, when needing noise reduction to stop working, rotary knob 8 makes fly valve vertical with airflow direction, thereby this moment, tail gas produced spiral motion and the effectively flame-out noise reduction of collision repeatedly in valve pocket.
