Embodiment Construction

[0014] The present invention provides a gasket used for mechanical sealing of a glass-lined reactor. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] Because the PTFE material has the following advantages: high temperature resistance - the working temperature can reach 200°C; corrosion resistance - it is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents; Climate - has the best aging life among plastics; high lubrication - has the lowest coefficient of friction among solid materials. Therefore, the gasket made of polytetrafluoroethylene can still maintain good sealing performance under the environment of strong corrosion, high temper...

Abstract

The invention discloses a sealing gasket, which is used for mechanical sealing of a glass-lined reactor. The sealing gasket is a polytetrafluoroethylene ring gasket, and a tooth-shaped The connection gap, the gaskets are fastened to each other at the connection gaps; the gaskets set the inner and outer diameters of their rings according to the size of the mechanical seal of the glass-lined reactor. Using the polytetrafluoroethylene gasket for mechanical sealing of glass-lined reactors can reduce equipment repair and maintenance workload while increasing output, and also reduce air pollution due to good sealing performance.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a sealing gasket used for the mechanical seal of a glass-lined reactor. Background technique [0002] The materials produced by the glass-lined reactor are highly corrosive and high-temperature media, such as figure 1 As shown, the traditional tetrafluoroasbestos gasket is easy to become soft and deformed in the environment of strong corrosion, high temperature and high pressure, and thus loses its sealing effect, so that the exhaust gas generated in the reactor pollutes the air in the workshop, especially when it is affected by the mechanical seal oil pan. After the engine oil overflows and penetrates into the gasket, the damage of tetrafluoroasbestos is accelerated. This type of gasket has a short service life and needs to be disassembled from the agitator to replace the gasket, which is labor-intensive and seriously affects production. [0003] Therefore, the prior art stil...
