Ozone-resistant mildew-proof rubber sealing gasket and construction method thereof

Abstract

The invention discloses an ozone-resistant mildew-proof rubber sealing gasket and a construction method thereof. The ozone-resistant and mildew-proof rubber sealing gasket comprises a body, wherein athrough hole is formed in the center of the body, and connecting holes running through the upper end and the lower end are formed in the circumference of the body. The body comprises an outer claddinglayer and an inner embedding layer, the inner circumference of the outer cladding layer is provided with a mounting cavity, the inner embedding layer is matched with the mounting cavity, and the inner embedding layer is glued in the mounting cavity. The connecting holes run through the outer cladding layer and the inner embedding layer respectively. The method comprises the steps of a, preparation before construction; b, erection of an auxiliary mounting device; c, positioning and mounting of the sealing gasket; d, embedding of the sealing gasket; and e, connection of a pipeline and the sealing gasket. The service life of the sealing gasket is greatly prolonged, the replacement frequency of the sealing gasket is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sealing equipment, and in particular relates to an ozone-resistant and mildew-proof rubber sealing gasket and a construction method thereof. Background technique [0002] Gasket is a kind of sealing spare parts used in machinery, equipment and pipelines as long as there is fluid. It uses internal and external materials to play a sealing role. The gasket is made of metal or non-metal plate material, which is made by cutting, stamping or cutting, and is used for the sealing connection between pipelines and the sealing connection between parts of machinery and equipment. According to the material, it can be divided into metal gasket and non-metal gasket. Metal pads include copper pads, stainless steel pads, iron pads, aluminum pads, etc. Non-metallic ones include asbestos pads, non-asbestos pads, paper pads, rubber pads, etc. [0003] Natural rubber gaskets are often used in existing sewage pipeline syste...

AI Technical Summary

Problems solved by technology

[0003] Natural rubber gaskets are often used in existing sewage pipeline systems. Although natural rubber gaskets have outstanding high and low temperature resistance, they maintain good elasticity in the temperature range of -70°C—+260°C and are easy to seal. , but there are many corrosive substances in the sewage pipeline, the natural rubber gasket has poor corrosion resistance and is prone to mildew, and the outside of the natural rubber gasket is polluted by ozone, which will accelerate the aging of the rubber gasket and easily cause cracks. As a result, its service life is low, it needs to be replaced frequently when used in the sewage pipeline system, and the maintenance cost is high
