Abstract
The invention discloses a kind of Novel air valve, including valve plug, valve body, valve plug is connected to valve body, and one end setting of the valve body has the gap, and other end oral area is provided with boss, and the inner cavity of valve body also sets up stepped hole, and boss is additionally provided with internal thread between gap；One end of the valve plug is provided with arc end part, and the other end of valve plug is provided with nut, connection external screw thread is also set up between nut and arc end part；Using above-mentioned technical proposal, since one end setting of the valve body has the gap, its other end oral area is provided with boss, one end of valve plug is provided with arc end part, arc end part is installed with stepped hole interference fit so that improves the sealing effect of air valve, and gap can not only allow gas to pass through air valve, also it can be that gap is closed by the pressure of gas, improve the sealing effect of air valve.
Description
Technical field
The present invention relates to air valve, more particularly to a kind of Novel air valve.
Background technology
Air valve is the significant components on compresser cylinder, it is responsible for the sucking and discharge of gas；The quality of air valve will be direct
Influence capacity, power consumption and the maintainability of compressor；
But in the prior art, pass through side wall since traditional air valve is given a shock the easy loosening of rear valve plug, valve body and valve plug
Cooperation prevents gas from leaking, and high-precision side wall coordinates difficulty of processing big, and prevents gas leakage effects poor.
Invention content
The technical problem to be solved in the present invention is to provide a kind of Novel airs that reasonable for structure, easy to process and sealing has been imitated
Valve.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of Novel air valve, including valve plug, valve body, valve plug are connected to valve body, and one end setting of the valve body has the gap,
Other end oral area is provided with boss, and the inner cavity of valve body also sets up stepped hole, and boss is additionally provided with internal thread between gap；The valve
One end of plug is provided with arc end part；The other end of valve plug is provided with nut, and the outer spiral shell of connection is also set up between nut and arc end part
Line.
Preferably, the first sealant is additionally provided in the arc end part, the thickness of the first sealant is 5mm-8mm.
Preferably, the boss is provided with chamfering, and the second sealant is fixed on boss, and the thickness of the second sealant is
3mm-5mm。
Preferably, the arc end part is more than step pore size, and arc end part is installed with stepped hole interference fit.
Preferably, the height in the gap is 0.1mm.
Using above-mentioned technical proposal, since one end setting of the valve body has the gap, other end oral area is provided with boss,
One end of valve plug is provided with arc end part, and arc end part is installed with stepped hole interference fit so that the sealing effect of air valve is improved,
And gap can not only allow gas by air valve, also can be that gap is closed by the pressure of gas, improve the sealing effect of air valve
Fruit.

Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but does not constitute limitation of the invention.In addition, disclosed below
The each embodiment of the present invention in involved technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figs. 1-3, a kind of Novel air valve, including valve plug 1, valve body 2, valve plug 1 are connected to valve body 2, the valve body 2
One end setting has the gap 3, enters air container convenient for gas, after the internal pressure increase of air container, the power of pressure to stitch
Gap 3 is closed so that air valve has better obturation effect；Its other end oral area is provided with boss 4, and boss 4 can be in air valve
Use during prevent the loosening of valve plug 1；The inner cavity of valve body 2 also sets up stepped hole 5, and boss 4 is additionally provided with interior between gap 3
Screw thread；One end of the valve plug 1 is provided with arc end part 6, and arc end part 6 is installed with the interference fit of stepped hole 5, improves air valve
Sealing effect；The other end of valve plug 1 is provided with nut 7, and connection external screw thread is also set up between nut 7 and arc end part 6.
In addition, the first sealant 8 is additionally provided in arc end part 6, the first sealant 8 can be elastic gel, thick
Degree is 5mm-8mm, in this embodiment, using 5mm, in the case of improving air valve sealing effect, the air valve damage avoided,
Improve the service life of air valve.
Further, boss 4 is provided with chamfering, and the second sealant 9 is fixed on boss 4, and the thickness of the second sealant 9 is
3mm-5mm, in this embodiment, using 3mm.
In addition, the height in gap 3 is 0.1mm, gas can be allowed by valve body 2, when the internal pressure of air container increases
After big, gap 3 be closed the power of valve body 2 by gas, improve the sealing effect of air valve.
Embodiments of the present invention are explained in detail above in association with attached drawing, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
