The second air hole for extending to outer end face is offered, steel ball is set in the inner cavity of spring base, and is also set in the inner cavity of spring base
It is equipped with the compression spring for acting on steel ball and being extrapolated, the diameter of steel ball is greater than the aperture of the first air hole, spring base opening
In the inner cavity of valve body, steel ball is acted on by compression spring and forms spherical surface to the first air hole for towards the first air hole interference press fitting
Sealing.
Wherein, sealing ring is folded between steel ball and the inner wall of valve body.
Wherein, sealing ring is corresponded on valve body offer limiting slot.
Wherein, two breather valves are installed on the inner wall of shell, are opened up on shell there are two installation cavity, two breather valves are pacified
Loaded in corresponding installation cavity, and the second air hole of a breather valve reclines shell, the second air hole back of another breather valve
To shell.
Wherein, the valve body interference press fitting of two breather valves is in corresponding installation cavity.
Alternatively, the second air hole reclines, the valve body interference of the breather valve of shell is pressed in an installation cavity, and second is ventilative
The direct interference of its spring base is pressed in another installation cavity by the breather valve of hole back to shell without valve body.
Wherein, opened up on shell there are two in corresponding installation cavity breather valve runner be connected to air cavity, two air cavitys by
The outer surface that corresponding air flue extends to shell forms a natural aspiration mouth and an exhaust outlet.
Alternatively, opened up on shell there are two in corresponding installation cavity breather valve runner be connected to air cavity, two air cavitys by
One air flue connection, and air flue extends to one blow vent of outer surface formation of shell.
To sum up, beneficial effects of the present invention are, compared with prior art, the motor water-proof valve assembly structure function
In on the motor body of all-sealed structure, inner cavity air pressure can be effectively adjusted, has fully ensured that waterproof performance, when internal high pressure expands
When can be vented automatically, when internal-combustion is on fire, moment anoxic is gone out open fire automatically, to realize waterproof, fire prevention, adjust internal pressure
Function, realize electric motors function break through.
