Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1, the present invention provides a schematic structural diagram of a vacuum preloading film sealing device (not including a surface sealing film 6), which includes a telescopic sleeve 3, an upper sealing ring 4, a lower sealing ring 2, a gasket 1 and a surface sealing film 6 (not shown in the figure).
The upper seal ring 4 and the lower seal ring 2 have the same shape and structure and are vertically symmetrical, and the structure of the two seal rings will be described in detail below by taking the lower seal ring 2 as an example. The lower seal ring 2 includes: annular seat and annular boss, annular boss vertical connection in the upper surface of annular seat, the internal diameter of annular seat is unanimous with annular boss internal diameter, and the external diameter of annular seat is greater than the external diameter of annular boss. For the lower sealing ring 2, the annular seat is arranged to increase the contact area of the lower sealing ring 2 and the surface sealing film 6, and the sealing performance is improved. For the upper sealing ring 4, the design structure of the annular seat is more favorable for grabbing and is convenient for later maintenance.
The upper end and the lower end of the telescopic sleeve 3 are respectively and tightly connected with the annular boss of the upper sealing ring 4 and the annular boss of the lower sealing ring 2 and are firmly bonded by sealant, so that the good sealing of the bonding part is ensured. It will be appreciated that in order for the outlet membrane monitoring tube 7 to pass smoothly through the telescoped sleeve 3, the inner diameter of the upper sealing ring 4 and the inner diameter of the lower sealing ring 2 should all be larger than the outer diameter of the outlet membrane monitoring tube 7.
