Description

Technical Field

[0001] The utility model relates to the field of air ducts, and particularly to a welding tooling for a circular valve air duct. Background Technique

[0002] The circular valve air duct is a ventilation device, usually used in mines or other places where ventilation is required. The design of this device helps to regulate the air flow and ensure air circulation to maintain a safe working environment. The core part of the circular valve air duct is the valve, which can control the size and direction of the air flow. The valve is usually controlled by a rotating device or a sliding device to adjust the opening size of the air duct. The air duct itself adopts a circular design, which helps to reduce the resistance of the air flow and make the air flow more smooth.

[0003] When installing the circular valve air duct, it is necessary to weld multiple air ducts together. In the prior art, after welding the connection of one section of the air duct, the welder needs to rotate the position of the air duct so that the un-welded connection of the air duct is exposed in front of the welder, and then the welder performs the welding. This makes the welding work not smooth enough, not convenient enough, time-consuming and laborious. Therefore, the technical personnel in this field provide a welding tooling for a circular valve air duct to solve the problems raised in the above background technique. Content of the Utility Model
