Description

Technical Field

[0001] This utility model relates to the field of airtight steel plate processing technology, specifically to a steel cover-type air cushion-type pressure regulating chamber steel plate combination clamp. Background Technology

[0002] Air-tight steel plates are structural materials used in steel-shrouded air-cushion pressure regulating chambers, typically made of special high-strength alloy steel. They possess high strength and corrosion resistance, can withstand high-pressure and high-temperature environments, and effectively prevent air leakage, thus ensuring the safe operation of the pressure regulating chamber. In the welding process of steel-shrouded air-cushion pressure regulating chambers, air-tight steel plates are usually connected using welding techniques. Positioning and clamping are crucial steps in the welding process. If the positioning and clamping are not secure, the steel plate may deform during welding, leading to uneven heating and cooling of the weldment and affecting weld quality. It can also result in inaccurate welding positions, preventing the weldment from achieving the desired shape and size. This requires more time and effort to fix the steel plate, potentially impacting welding efficiency. Therefore, a steel plate combination clamp for steel-shrouded air-cushion pressure regulating chambers is developed to ensure precise correspondence between the clamp position and the welding position.
