Description

Rapid manufacturing device for non-rigid sealing gasket TECHNICAL FIELD

[0001] The present application relates to the field of gasket manufacturing for thermal power plants, and particularly relates to a rapid manufacturing device for non-rigid sealing gaskets. BACKGROUND

[0002] Non-rigid sealing gaskets are mainly used to ensure the sealing of various devices and systems at the connection part, to prevent fluid leakage, and thus to ensure the safe and efficient operation of the power plant. Non-rigid gaskets can fill the small gaps between the flanges or connecting parts of devices such as pipes, valves, pumps, and heat exchangers, and provide good sealing effect.

[0003] In many parts of thermal power plants, non-rigid gaskets such as barley paper gaskets, oil-resistant asbestos gaskets, and sealing gaskets are used. The manufacturing of these non-rigid sealing gaskets is usually done by on-site technicians using a hammer to beat the entire gasket or using a caliper to measure the size and then cutting it with scissors. This operation process is complicated and time-consuming, and the cutting surface is not flat when cutting, which may cause the gasket to leak and pose an unpredictable safety hazard to on-site production safety.
