Embodiment Construction

[0013] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

[0014] like figure 1 As shown, a double-sealing protection device is characterized in that: the device includes a flange 1, a groove 2, a gasket 5, etc.; wherein, four first-level bolt holes 3 are processed on the flange; Four secondary bolt holes 4 are machined on the groove; the flange is used in cooperation with another same flange, and the grooves are filled with washers; the grooves provided with bolt holes in the device are matched with corresponding expansion bolts use.

[0015] Gasket 5 matches the shape of sealing groove 2. Pad 5 can be a rubber flange gasket, or a metal graphite wound gasket, preferably a metal graphite wound gasket, and is more suitable to have a bolt hole.

[0016] During implementation, two metal grap...

Abstract

The invention relates to a twice sealing protective device. The twice sealing protective device is characterized by comprising a flange, grooves, gaskets and the like, wherein four primary bolt holes are processed in the flange; four secondary bolt holes are processed in the grooves; the flange is matched with another same flange for use; and gaps among the grooves are filled with the gaskets. According to the device, the grooves with the bolt holes are matched with corresponding expansion bolts for use. Compared with an existing device, the twice sealing protective device is remarkably improved in sealing property, is long in service life and is affordable, and reduces environmental pollution and saves resources.

Description

technical field [0001] The invention relates to the technical field of mechanical airtight container sealing, in particular to a double-sealing protection device. Background technique [0002] At present, most of the existing sealing flanges are planar, and the two flanges welded to the pipeline are symmetrically installed together, which is easy to cause gap leakage, which not only causes unnecessary waste, but also pollutes the surrounding environment and shortens the service life. service life. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and the problem to be solved is to provide a double sealing protection device. [0004] In order to solve the problems existing in the background technology, the present invention adopts the following technical solutions: a double sealing protection device, characterized in that: the device includes flanges, grooves, gaskets and the like.
