The valve of prior art is in real work, due to the effect of air pressure, can be collided between valve body and bonnet, therefore can the company of sending
The impact sound of continuous bang bang, and collision if things go on like this can directly affect the usage cycles of valve, and cost input is larger.
Therefore, in order to solve above-mentioned problem, spy provides a kind of new technical scheme.
The content of the invention
It is an object of the invention to provide it is a kind of set up sound attenuation assembly, engine valve rational in infrastructure and convenient and practical.
It is of the invention to be for the technical scheme that above-mentioned technological deficiency is used：
A kind of engine valve, including valve body and bonnet, the end wall of the valve body are shaved one section and the position are provided with case,
The inwall of the case is provided with a rotating shaft, and the side of the bonnet is provided with jack, and bonnet is interspersed in rotating shaft by jack
On, the opening or closure of bonnet are realized by the rotation of rotating shaft, the case is provided with sound attenuation assembly in the top position of rotating shaft
Bonnet is abutted, the width of the sound attenuation assembly protrudes from shroud body and the top position extended at the top of case, the noise elimination
Component includes connecting seat and eliminated the noise to wrap, and bag of eliminating the noise is paid by pin lock forms integral structure on connecting seat.
Further, the two ends of the connecting seat are symmetrically arranged with one group of chuck, and the noise elimination, which is wrapped, to be provided with and chuck
The neck being adapted.
Further, the bag of eliminating the noise includes stainless steel layer, thermal insulation layer and plastic layer nested successively from inside to outside, and not
Rust steel layer, thermal insulation layer and plastic layer are the convex closure structure for being similar to pot cover.
Further, the edge placement of the plastic layer is provided with flange.
The beneficial effects of the invention are as follows：The present invention sets up sound attenuation assembly between valve body and bonnet, eliminate the noise bag and connecting seat
Assembling forms integral structure, and simple to operate quick, easy disassembly can effectively reduce the collision of valve body and bonnet and its bring
Impact sound, and plastic layer setting can be substantially reduced eliminate the noise bag weight, the cost of material is low, noise reduction environmental protection.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of sound attenuation assembly of the present invention.
Wherein, 1, valve body, 2, bonnet, 3, case, 4, rotating shaft, 5, jack, 6, sound attenuation assembly, 7, connecting seat, 8, bag of eliminating the noise,
9th, chuck, 10, neck, 11, pin, 12, stainless steel layer, 13, thermal insulation layer, 14, plastic layer, 15, flange.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, does not constitute the restriction to protection scope of the present invention.
A kind of engine valve as depicted in figs. 1 and 2, including valve body 1 and bonnet 2, the end wall of valve body 1 be shaved one section and
Case 3 is provided with the position, the inwall of case 3 is provided with a rotating shaft 4, and the side of bonnet 2 is provided with jack 5, and bonnet 2 is logical
Cross jack 5 to be interspersed in rotating shaft 4, the opening or closure of bonnet 2 are realized by the rotation of rotating shaft 4, case 3 is in the top of rotating shaft 4
Position is provided with sound attenuation assembly 6 and abuts bonnet 2, and the width of sound attenuation assembly 6 protrudes from the body of case 3 and extends to the top of case 3
Top position, sound attenuation assembly 6 include connecting seat 7 and eliminate the noise bag 8, eliminate the noise bag 8 by pin 11 lock pay on connecting seat 7 formed
Integral structure.
In the present embodiment, the two ends of connecting seat 7 are symmetrically arranged with one group of chuck 9, are provided with and chuck 9 on bag 8 of eliminating the noise
The neck 10 being adapted, bag 8 of eliminating the noise is paid on the chuck 9 of connecting seat 7 and with the lock of pin 11 by the inlay card of neck 10 so that eliminated the noise
Bag 8 and the assembling of connecting seat 7 form integral structure, are easy to the dismounting of sound attenuation assembly 6.
In the present embodiment, bag 8 of eliminating the noise includes stainless steel layer 12, thermal insulation layer 13 and plastic layer nested successively from inside to outside
14, and stainless steel layer 12, thermal insulation layer 13 and plastic layer 14 are the convex closure structure for being similar to pot cover, the setting of plastic layer 14 can show
The weight of mitigation noise elimination bag 8 is write, fee of material is reduced, and substantially 8 radiated noise is wrapped in reduction noise elimination, improves corrosion resistance.
