When flowing in first passage 13 together with interior gas and fluid, the air pressure in air cavity 12 can reduce.Due to the pressure in air cavity 12
Less than external pressure, thus the small club of silica gel is attracted and is moved away from air inlet 151.When silica gel bead is far from air inlet
When 151, interval forms air inlet gap between silica gel bead and air inlet 151.In this way, external air source can pass through air inlet gap
It enters in air cavity 12.In the process, pressured state can be in by rebounding.When fluid impact silica gel bead in air cavity 12,
The small club of silica gel moves towards close to air inlet 151.Meanwhile it rebounds and can release stress, and the pressure that spring is discharged can push
Silica gel bead is moved towards close to air inlet 151, until silica gel bead is plugged in air inlet 151.By being equipped with such elasticity
Component 20 and closeouts 30 can not only realize self-priming bleed, and the fluid being also prevented from air cavity 12 flow to outside.
Certainly, elastomeric element 20 can also be made of rubber, metal clips.No matter which kind of mode elastomeric element 20 uses,
Closeouts 30 is made to block air inlet 151 as long as elastic stress can be provided.Similarly, closeouts 30 can be by ball, modeling
Pellet, glass marble, steel ball composition.No matter which kind of mode is closeouts 30 use, as long as air inlet 151 can be blocked.
In addition, elastomeric element 20 and closeouts 30 can also be made of check valve.Check valve is used to limit gas, fluid
It is only capable of being flow in air cavity 12 by outside.Meanwhile in order to which fluid is further prevented to flow to outside, can also match in movable chamber 152
Silica gel pad 40 is equipped with, and the aperture of the endoporus of silica gel pad 40 is less than the aperture of silica gel bead.
The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
