The invention discloses a pipe-in-pipe with a spring return drawing function. The pipe-in-pipe comprises a bent pipe and a drawing hose positioned in the bent pipe, and further comprises a front joint, a check block, a spring, a rear joint and a hard inner pipe which are sequentially arranged from front to back along the water flow direction, one end of the front joint is fixed and communicated with the drawing hose, the other end of the front joint is connected with a shower head, the rear joint is in sliding connection with the bent pipe and fixed to the drawing hose, the check block is fixed to the inner wall of the bent pipe, a spring surrounds the drawing hose, one end of the spring abuts against the check block, the other end of the spring abuts against the rear joint, and one end of the hard inner pipe is in sliding connection with the rear joint and communicated with a main body water path. The other end of the hard inner pipe extends to the middle of the drawing hose and communicates with the drawing hose. According to the pipe-in-pipe, specific application of the step-by-step transfer fractional step method for cost accounting in power line loss accumulation is realized.
本发明公开了一种具有弹簧回位抽拉功能的管中管，包括弯管以及位于弯管中的抽拉软管，还包括沿水流方向自前而后依次设置的前接头、挡块、弹簧、后接头以及硬内管，前接头一端与抽拉软管固定并联通，前接头另一端连接花洒头，后接头与弯管之间为滑动连接且与抽拉软管固定，挡块固定在弯管内壁上，弹簧环绕在抽拉软管上且一端与挡块相抵，弹簧另一端与后接头相抵，硬内管一端与后接头滑动连接并连通主体水路，硬内管另一端延伸至抽拉软管中部并连通抽拉软管。本发明实现了成本核算的逐步结转分步法在电力线损累积中的具体运用。
