Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a bellows inner diameter welding protection device. Background Technique

[0002] Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows wall is relatively thin and has high sensitivity. The measurement range is from dozens of pascals to dozens of megapascals. Its open end is fixed, and the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity. When working, under the action of internal pressure, it elongates along the tube length direction, causing the movable end to generate a displacement in a certain relationship with the pressure. The movable end drives the pointer to directly indicate the magnitude of the pressure; when processing the bellows, it is necessary to weld and assemble the pipe segments. Since the weld seam is small, it is necessary to use an eyepiece to magnify and observe. During observation, welding slag is likely to splash from the bottom onto the personnel, causing harm.
