Problems solved by technology

[0002] In the prior art, the sealing gaskets are mostly made of flexible materials, such as asbestos, rubber, etc., due to the poor ability of such materials to bear stress, after a period of use, due to the pressure and ambient temperature, the sealing gaskets It is easy to age or relax, and the sealing performance becomes poor or even loses the sealing performance. At the same time, it is easy to bend and deform during installation, which affects the sealing effect
There are also sealing gaskets made of metal materials. Because the metal tube is hollow, the pressure resistance and compression rebound performance are limited, and the scope of application is narrow. On this basis, an improved metal sealing gasket is used. On the hollow metal tube There is an opening, although it plays the role of self-tightening seal, it is prone to bursting and being blocked by the medium when used, and the ideal sealing effect cannot be achieved.

Embodiment Construction

[0018] See attached figure 1 to attach figure 2 , a metal pipe ring sealing gasket, comprising a ring-shaped metal pipe 1 and a flexible sealing filler 2 filled in the inner cavity of the metal pipe 1 . The metal tube 1 is made of carbon steel, stainless steel, copper, aluminum, Monel, Inconel, titanium and other materials, and the flexible sealing filler 2 is made of non-metallic materials, such as graphite, fiber, polytetrafluoroethylene One or more mixtures of vinyl fluoride and resin.

[0019] The cross-section of the metal pipe 1 is circular. The wall thickness of the metal tube 1 is in the range of 0.1 to 3 mm, preferably in the range of 0.3 to 0.5 mm, and the outer diameter of the metal tube 1 is in the range of 2 to 50 mm, preferably in the range of 4 to 25 mm. The flexible sealing filler 2 fills the inner cavity of the metal pipe 1 .

[0020] A method for manufacturing a metal pipe ring sealing gasket, comprising the following steps: ①. Filling the inner cavity o...

Abstract

The present invention relates to a metal tube ring gasket seal. It includes a ring metal tube and a flexible seal filling material which can be filled into the internal cavity of said metal tube. Its manufacture method includes the following steps: (1), filling the flexible seal filling material into the internal cavity of metal tube; (2), bending and making the metal tube whose internal cavity is fitted up with the flexible seal filling material into the form of ring; and (3), butt-welding two end noses of said ring-shaped metal tube so as to obtain the invented ring gasket seal.
