Abstract
The utility model discloses a miniature pneumatic valve amortization improvement structure that loses heart, including valve body, connection piece, amortization sponge and amortization cavity, both ends face is rubberized around the connection piece and has seted up a plurality of through-hole of breathing in the horizontal direction, the amortization sponge is placed in the amortization cavity, the connection piece front end face is connected with the valve body side fixed connection who takes the mouth that loses heart, rear end face and amortization cavity fixed connection, a plurality of through-hole of breathing in and the valve body lose the position of mouth, quantity, size and correspond the matching completely, set up a plurality of micropore of giving vent to anger on the amortization cavity; the cavity effect through amortization sponge and amortization cavity is inhaled the sound step by step and is fallen and make an uproar, and the noise cancelling effect is good and can effectively fall and make an uproar, and the result of use is ideal to use and experiences and is good, effectively satisfies customer user demand.
Description
Technical Field
The utility model belongs to the pneumatic valve field, in particular to disappointing amortization of miniature pneumatic valve improves structure.
Background
The pneumatic valve can produce very big noise when disappointing, the noise is experienced and can produce great influence to its result of use and use, experience in order to have better result of use and use, present way is with the simple seal of amortization sponge in the gas outlet of intaking, utilize the sound absorption nature of sponge to filter the absorption air current noise, certain effect can be played in this kind of simple processing, but the noise cancelling effect is very limited, can not effectively fall and make an uproar, the result of use still is not ideal enough, use experience is also not good enough, can not effectively satisfy customer's user demand.
The to-be-solved technical problem of the utility model is to provide a miniature pneumatic valve amortization that can effectively fall makes an uproar, the noise cancelling effect is good, the result of use ideal, use experience good, effectively satisfy customer user demand improves structure.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned prior art noise cancelling effect effective, can not effectively fall make an uproar, result of use ideal inadequately, use experience not good enough, can't effectively satisfy customer user demand scheduling problem, the utility model discloses a following technical scheme:
the utility model provides a disappointing amortization of miniature pneumatic valve improves structure, including valve body, connection piece, amortization sponge and amortization cavity, both ends face all coats with glue and has seted up a plurality of air passing through-hole on the horizontal direction around the connection piece, the amortization sponge is placed in the amortization cavity, terminal surface and the valve body area side fixed connection, rear end face and the amortization cavity fixed connection of disappointing the mouth before the connection piece, the position, quantity, the size of the mouth that the air passing through-hole of a plurality of and valve body correspond the matching completely, the micropore of giving vent to anger of a plurality of has been seted up on the amo.
As an improvement of the utility model, the density of the silencing sponge is 28-32.
As a further improvement, the diameter of the air outlet micropore on the silencing cavity is 3 mm.
The beneficial effects of the utility model reside in that: the cavity effect through amortization sponge and amortization cavity is inhaled the sound step by step and is fallen and make an uproar, and the noise cancelling effect is good and can effectively fall and make an uproar, and the result of use is ideal to use and experiences and is good, effectively satisfies customer user demand.
Drawings
Fig. 1 is an exploded schematic view of an embodiment of the present invention.
Fig. 2 is a schematic view of the overall assembly structure of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an improved structure for air release and noise reduction of a micro air valve comprises a valve body 1, a connecting piece 2, a noise reduction sponge 3 and a noise reduction cavity 4, wherein the front end surface and the rear end surface of the connecting piece 2 are both coated with glue and are provided with a plurality of air through holes 21 in the horizontal direction, the noise reduction sponge 3 is placed in the noise reduction cavity 4, the front end surface of the connecting piece 2 is fixedly connected with the side surface of the valve body 1 with an air release opening, the rear end surface of the connecting piece is fixedly connected with the noise reduction cavity 4, the air through holes 21 are completely matched with the position, the number and the size of the air release opening of the valve body 1 correspondingly, the noise reduction cavity 4 is provided with a plurality of air outlet micropores (not visible in the figure), when the air valve is deflated, air flow is discharged from the air release opening, when entering the noise reduction cavity through the air through holes, firstly passes through the sound absorption and, further absorb and reduce the air current noise, the air current is discharged from the micropore of giving vent to anger of amortization cavity at last, can realize greatly like this and fall the noise, the noise cancelling effect is very ideal, and the noise is effectively restrained, falls and makes an uproar and reaches 10DB, and the air valve loses air the noise and is almost inaudible.
The density of the silencing sponge is 28-32, and the diameter of the air outlet micropores on the silencing cavity is 3mm, so that the silencing and noise reduction effects are better.
The beneficial effects of the utility model reside in that: the cavity effect through amortization sponge and amortization cavity is inhaled the sound step by step and is fallen and make an uproar, and the noise cancelling effect is good and can effectively fall and make an uproar, and the result of use is ideal to use and experiences and is good, effectively satisfies customer user demand.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
