AI Technical Summary

Problems solved by technology

Since the flange gasket and the flange are independent of each other, when the bolts are not locked to the maximum, the two flanges cannot achieve a good seal; in addition, there will be mechanical vibration during use After a long time, there will be looseness between the flanges. If the bolts are not locked in time, the sealing performance will be reduced.

Embodiment Construction

[0028] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0029] like Figure 1-4 As shown, a sealing flange includes a first flange 1 and a second flange 2 that cooperate with each other, a flange gasket is provided between the first flange 1 and the second flange 2, and the first A flange 1 and a second flange 2 are fastened and connected by at least two bolts 3, and the connecting surfaces of the first flange 1 and the second flange 2 are respectively provided with mutually engaging sealing rings 4.

[0030] As a preferred technical solution of the present invention, the material of the sealing ring 4 is asbestos rubber plate, PTFE plate or polyethylene plate.

[0031] As a preferred technical solution of the p...

Abstract

The invention discloses a sealing flange, which comprises a first flange plate and a second flange plate, wherein the first flange plate and the second flange plate are matched with each other, a flange gasket is arranged between the first flange plate and the second flange plate, the first flange plate and the second flange plate are fastened and connected through at least two screw bolts, and mutually engaged sealing rings are respectively arranged on connecting surfaces of the first flange plate and the second flange plate. Compared with the prior art, the sealing flange has the beneficial effect that when the screw bolts are not locked to the maximum degree, or when the looseness is generated between the flange plates due to mechanical vibration, good sealing performance can still be maintained between the flange plates.

Description

technical field [0001] The invention relates to a sealing flange. Background technique [0002] Flange is also called flange or flange. Flanges are parts that connect pipes and pipes or valves to each other, and are connected to the pipe end. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded flanges, welding flanges and ferrule flanges. [0003] Flange is also called flange flange. Flanges are parts that are connected to each other between pipes and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the...
