Problems solved by technology

[0002] The flange is a part that connects the pipe to the pipe. It is connected to the pipe end. There are holes in the flange. The bolts make the two flanges tightly connected. It is the most common in engineering. The normally used flange will have water seepage. The leakage of liquid will have a certain impact on the user, and it is inconvenient to install and disassemble the internal gasket, which is easy to be damaged. Therefore, it is necessary to repair the connecting flange. Anti-seepage treatment

Abstract

The invention discloses an anti-seepage treatment process of a connecting flange. The anti-seepage treatment process comprises the following steps of S1, making a drawing; S2, machining and manufacturing the flange; S3, machining the waterline of the flange; S4, cleaning fragments and flushing the fragments on the flange through water flow; S5, selecting a material; S6, stamping a graphite composite base plate; S7, conducting trial cutting on the graphite composite base plate; S8, punching the graphite composite base plate, conducting punching on the graphite composite base plate after trial cutting is errorless to obtain graphite composite gaskets; S9, cleaning the fragments after punching on the graphite composite base plate; S10, conducting installation; and S11, inspecting the effect,using the flange and observing the anti-seepage effect of the flange. The anti-seepage treatment process is more scientific and reasonable, and the process cost can be reduced. The anti-seepage treatment process provided by the invention is simple in step, a labyrinth seal is formed, and liquid seepage can be avoided. Moreover, installation and dismantling are convenient, and the connecting flangeis not prone to damage. Corrosion of a medium and oxygen in outside air to the gaskets can be prevented.

Description

technical field [0001] The invention relates to the field of flanges, in particular to an anti-seepage water treatment process for flanges. Background technique [0002] The flange is a part that connects the pipe to the pipe. It is connected to the pipe end. There are holes in the flange. The bolts make the two flanges tightly connected. It is the most common in engineering. The normally used flange will have water seepage. The leakage of liquid will have a certain impact on the user, and it is inconvenient to install and disassemble the internal gasket, which is easy to be damaged. Therefore, it is necessary to repair the connecting flange. Carry out anti-seepage treatment. Contents of the invention [0003] The object of the present invention is to provide an anti-seepage water treatment process for connecting flanges, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention p...
