Anti-vibration air pipe module

Abstract

The invention discloses an anti-vibration air pipe module. An air way pressure pulse peak value is attenuated to the greatest extent; and the generation length of cracks in the welding link is reduced. The anti-vibration air pipe module is characterized by comprising two joints and a pipe module connected between the two joints; the pipe module comprises an outer hose, and multiple capillary pipesarranged in the outer hose; the joints are provided with step holes; the capillary pipes are arranged in the step holes; first welding flanges for welding the outer hoses are arranged on the end surfaces of the joints; second welding flanges for the capillary pipes are arranged on the edges of the step holes; and the capillary pipes are flexibly connected between the two joints.

Description

technical field [0001] This invention relates to connecting tubes, and more particularly to a vibration-resistant air tube assembly. Background technique [0002] The air pipe assembly for transporting SF6 gas is usually composed of stainless steel straight pipes with welded pipe joints at both ends. The overall connection is rigid, and the welding stress is difficult to completely eliminate. It is suitable for working environments without vibration sources. Because the high-voltage switch circuit breaker has a large impact and vibration during the opening and closing operation, the weld between the straight pipe of the air pipe assembly and the joint often causes weld cracking due to vibration; Larger diameters are easily affected by the peak pressure pulsation of the gas path, and the control accuracy is poor, which often leads to false triggering of signals. Therefore, shock absorption and improving instrument control accuracy to ensure the safe operation of the system h...
