Embodiment
Referring to the accompanying drawing that the utility model embodiment is shown, below the utility model will be described in more detail.Yet the utility model can be with many multi-form realizations, and should not be construed as the embodiment's who is subject in this proposition restriction.On the contrary, it is abundant and complete open in order to reach proposing these embodiments, and makes those skilled in the art understand scope of the present utility model completely.In these accompanying drawings, for clarity sake, may amplify size and the relative size in layer and region.
With reference to figure 3-4, the utility model provides a kind of vacuum flow and vacuum degree automatic control device, and the barometric pressure that is arranged on a vacuum cavity 1 is flowed through in passage, for vacuum flow is controlled.Vacuum flow and vacuum degree automatic control device that the utility model provides, according to the size of the passage of the automatic Gas regulation baric flow of atmospheric size warp, thereby realize the adjusting of vacuum flow, and the utility model is simple in structure, takes up room little, cost-saving.
Concrete, this a kind of vacuum flow and vacuum degree automatic control device comprise a round iron plate 2, on iron plate 2, offer and be equipped with a curve bath 21, make the center position formation one of iron plate 2 there is flexible shell fragment 22, when shell fragment 22 pressurizeds depart from the plane at iron plate 2 places, on the central position of iron plate 2, form one compared with barometric pressure passage; Certainly, the formation of shell fragment 22 also can realize by other means originally, for example, can first on iron plate 2, directly open one compared with big hole, and then a shell fragment 22 is installed on the circular hole position of iron plate 2, can design as the case may be, was not restricted herein.On the central position of shell fragment 22, be also provided with an aperture 23, when shell fragment 22 is during in initial position, aperture 23 is as a less pressure channel, and wherein setting position and the large I of aperture 23 on shell fragment designs according to tool situation, is not restricted herein.The utility model replaces ball control gear of the prior art or one-way valve control gear to control vacuum flow by iron plate 2, and its thickness is less, takes up room less, and saves raw material.
In the present embodiment, this vacuum flow and vacuum degree automatic control device also comprise a section bar 4, and the shape of section bar 4 and size are decided by the flow through shape size of passage of the barometric pressure of vacuum cavity 1.On the central position of section bar 4, be provided with a ladder hole, ladder hole comprises large footpath through hole 5 and path through hole 6, and large footpath through hole 5 is towards vacuum cavity 1, and path through hole 6 is towards the external world.In the present embodiment, the diameter of iron plate 2 is less than or equal to the diameter of large footpath through hole 5, and the diameter of shell fragment 22 is more than or equal to the diameter of path through hole 6; Iron plate 2 is arranged in large footpath through hole 5, and by a fastening spring 3, is arranged on the boundary position place of large footpath through hole 5 and path through hole 6, and fastening spring 3 is pressed on iron plate 2 on the position except curve bath 21 and shell fragment 22; Wherein, iron plate also can be installed in section bar 4 by other means, is not restricted herein.The barometric pressure that the section bar 4 that iron plate 2 is installed is directly installed to vacuum cavity 1 is flowed through in passage; Certainly, this vacuum flow and vacuum degree automatic control device also can not arrange section bar 4, the channels designs of now barometric pressure of vacuum cavity 1 can being flowed through becomes the structural type of ladder hole as described above, the barometric pressure that iron plate 2 is directly installed to vacuum cavity 1 is flowed through in passage, can design as the case may be, not be restricted herein.
