Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a state diagram of the present invention in use;
fig. 3 is a side schematic view of a sealing piston of the present invention.
Detailed Description
As shown in fig. 1, the composite pipe includes a pipe body 1, one end of the pipe body 1 is connected to a pipe input pipe 11, the other end is connected to a pipe output pipe 12, two sealing pistons 3 are arranged in the pipe body 1, the sealing pistons include a movable piston 31 and a fixed piston 32, the two sealing pistons 3 seal the whole pipe body 1, a sealing cavity 4 is formed between the two sealing pistons 3, a water inlet cavity 2 is formed between the outer end of the movable piston 31 and the pipe input pipe, a water outlet cavity 22 is formed between the fixed piston and the pipe output pipe, more than one elastic conveying pipe 6 is arranged between the two sealing pistons 3, and the water inlet cavity 2 and the water outlet cavity 22 are connected and communicated by the more than one elastic conveying pipe 6.
Wherein, be provided with first stopper ring 13 in the pipeline main part near pipeline input pipe 11 one side, be used for restricting movable piston 31 towards pipeline input pipe 11 motion, the both sides of fixed piston 32 all are provided with second stopper ring 8, be used for fixing fixed piston in the pipeline main part, when fracture 14 appears, the gas in the sealed chamber runs out from the fracture this moment, the movable piston of one side at this moment moves towards the fracture fast, when moving to the fracture position, through the sealed fracture of movable piston, as shown in fig. 2, shutoff fracture 14 this moment, prevent the entering of outside dust and steam, shorten the elasticity conveying pipe simultaneously, after the shutoff, each elasticity conveying pipe continues to carry fluid medium, the whole pipeline realizes continuing the transmission.
As shown in fig. 3, a through hole 34 is formed in the sealing piston 3 opposite to each elastic conveying pipeline, two ends of each elastic conveying pipeline 6 are respectively installed in the through holes of the two sealing pistons and are bonded and fixed by waterproof glue, a fluid medium enters the water inlet cavity, then enters each elastic conveying pipeline through the movable piston 31, and finally is discharged through the fixed piston, so that normal conveying is realized.
