Title:
PROTECTIVE TUBE SUPPORT STRUCTURE OF TEMPERATURE REDUCER
Document Type and Number:
Japanese Patent JP2019168149
Kind Code:
A
Abstract:
To suppress displacement to the pipe axis direction of a protective tube, the displacement that is caused by abrasion of an outer circumferential surface of a pin and an inner face of a hole-shaped pin locking part.MEANS FOR SOLVING THE PROBLEM: A pin 9 is provided to a header 1 in a fixing manner, and is protruded to the inside in the tube diameter direction. A hole-shaped pin locking part 10 is provided to a protective tube 3 in a fixed manner, and can be locked to the pin 9. The movement in the pipe axis direction and the movement in the peritubular direction of the protective tube 3 to the header 1 are regulated by that the pin locking part 10 is locked to the pin 9. The outer circumferential surface of the pin 9 has a taper-shaped inclined outer surface 12 that is reduced in diameter or increased in diameter toward the inside in the tube diameter direction. The inner face of the pin locking part 10 is opposed with the inclined outer surface 12 of the pin 9, and has a taper-shaped inclined inner surface 18 that is reduced in diameter or increased in diameter toward the inside in the tube diameter direction.SELECTED DRAWING: Figure 4
