SOUND PIPE AND SOUND PIPE ASSEMBLY
The invention provides a sounding pipe and a sounding pipe assembly. The sounding pipe comprises a pipe main body and a pipe joint which are inserted and matched in the axial direction of the sounding pipe; the pipe joint comprises a first radial plastic deformation section, an elastic deformation section and a second radial plastic deformation section which are sequentially arranged in the axial direction. The elastic deformation section is provided with a protruding ring wall, a first end face ring wall and a second end face ring wall, the protruding ring wall and the pipe body are oppositely arranged in the radial direction, and the protruding ring wall is bent in the direction away from the pipe body. A mounting groove is defined by the protruding ring wall, the first end face ring wall, the second end face ring wall and the pipe body, a sealing ring is arranged in the mounting groove, and the peripheral wall of the sealing ring is attached to the protruding ring wall. Even if the sounding pipes at the two ends of the sounding pipe are bent greatly, the elastic deformation of the thin-wall steel pipe can still provide enough extrusion force compensation, so that the sealing rings can continue to form effective sealing.
本发明提供一种声测管和声测管组件。声测管包括沿着声测管的轴向插接配合的管主体和管接头；管接头包括沿着轴向依次布置的第一径向塑变区段、弹性变形区段和第二径向塑变区段；弹性变形区段设置有凸起环壁、第一端面环壁和第二端面环壁，凸起环壁与管主体沿着径向相对设置，凸起环壁朝向远离管主体的方向弯曲；凸起环壁、第一端面环壁、第二端面环壁与管主体围成安装槽，安装槽内设置有密封环，密封环的外周壁与凸起环壁贴合。该声测管即使两端声测管发生较大弯折量，薄壁钢管的弹性变形依然可以提供足够的挤压力补偿，使密封圈可以继续形成有效密封。
