Problems solved by technology
[0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Pipe fittings and equipment have their own flanges, which are also flange connections. Flange connections are an important connection method for pipeline construction. Flange connections are easy to use and can withstand large pressures. In industrial pipelines, the use of flange connections It is very extensive, but flange installation must be installed with flange pads, but in long-term use, there are often pipeline leakage problems caused by factors such as flange pad aging and damage, resulting in waste and even safety hazards

Embodiment Construction
[0008] The present invention will be described in further detail below according to the drawings and embodiments.
[0009] As shown in the figure, the sealing flange disc includes the flange upper piece 1 and the flange lower piece 2. A groove 5 is set between hole one 4 and the upper pipe 3, the flange lower piece 2 is connected to the lower pipe 6, and the flange lower piece 2 is provided with a screw hole two 7, which is combined with the screw hole one 4 for fixing the upper Protrusion 8 is arranged between pipe 3 and lower pipe 6, screw hole 2 7 and lower pipe 6, and the cross-sectional shape of described groove 5 is the same as that of protrusion 8, which is convenient for installation and placement of sealing gaskets.
[0010] As shown in the figure, the cross-section of the bump 8 is stepped, the groove 5 and the bump 8 are annular, and a sealing gasket is arranged between the groove 5 and the bump 8. The sealing gasket used is small and not easy to Aging is damaged, ...

The invention relates to a flange piece with a leak tightness, and used for solving the problem that the flange piece is inadequate in the leak tightness due to the damaged flange gasket. The flange piece is characterized in that a groove is formed between each of screw holes 1 formed in an upper flange piece and an upper pipe; a convex block matched with each of the grooves is arranged between each of screw holes 2 formed in a lower flange piece and a lower pipe; and a sealing gasket is arranged between the grooves and the convex blocks. The flange piece with the leak tightness has the benefits as follows: the used sealing gasket is smaller and not easy to age and damage, so that the sealing effect is better, the positioning of the grooves and the convex blocks is easier, the use is convenient, and the effect is good.
