Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a sealing device for a high-pressure boiler. Background Art

[0002] High-pressure boiler integrated automation equipment, also known as electric heating steam generator, is mainly composed of water supply system, automatic control system, furnace and heating system and safety protection system. Its basic working principle is: through a set of automatic control devices, ensure that the liquid controller or high, medium and low electrode probes feedback control the opening and closing of the water pump, the length of water supply and the heating time of the furnace during operation; the maximum steam pressure adjusted by the pressure relay is continuously output with the continuous output of steam, and the water level in the furnace continues to drop. When it is at a low water level (mechanical) or a medium water level (electronic), the water pump automatically stops at a high water level. At the same time, the electric heating tube in the furnace continues to heat, and steam is continuously generated. The pointer pressure gauge on the panel or the top of the top immediately displays the steam pressure value, and the entire process can be automatically displayed by the indicator light.

[0003] At present, the existing high-pressure boiler outlet pipe is installed with a threaded pipe and maintained sealed by a ring-shaped sealing gasket. However, since the air flow will vibrate during the pipeline transmission process, the threaded pipe will become loose, which in turn affects the sealing of the high-pressure boiler.
