[0008] The working principle of the utility model is: the sealing pipe is threadedly connected to the outer wall of the PE pipe body, and then the piston on the connecting rod is driven to move by rotating the pull block, the piston moves to the inside of the PE pipe body, the outlet is blocked and sealed, and then the PE pipe body and the sealing pipe are fixed by a fixing mechanism, thereby improving the sealing performance of the sealing pipe to the PE pipe body.

[0009] A sealing ring 1 is fixed in the sealing tube, a ring groove 1 is provided on the PE tube body, and a sealing ring 2 is fixed in the ring groove 1.

[0010] By adopting the above structure, the sealing performance of the sealing pipe to the PE pipe body is improved by installing the sealing ring 1 and the sealing ring 2.

[0011] The fixing mechanism comprises a fixing rod rotatably connected to the outer wall of the PE pipe body, a notch is provided on the sealing pipe, a clamping block is fixed to the right end of the fixing rod, and the notch is adapted to the clamping block.

[0012] By adopting the above structure, the PE pipe body and the sealing pipe are positioned by installing the notch and the block, so as to avoid the threaded connection from loosening and resulting in poor sealing effect.

[0013] The clamping block is provided with an installation groove, a spring is fixed in the installation groove, a clamping column is slidably connected in the installation groove, a circular groove is provided in the groove, a sliding opening connected to the installation groove is provided on the clamping block, and a sliding bar extending from the sliding opening is fixed on the clamping column.

[0014] With the above structure, by installing the clamping column and the circular groove, the clamping column is driven to retract into the installation groove by sliding the slide bar. When the clamping block on the fixing rod is inserted into the groove, the slide bar is released, and the clamping column is bounced into the circular groove by the elastic force of the spring, thereby realizing a fixed connection between the PE pipe body and the sealing pipe and preventing the threaded connection from loosening.

[0015] A convex ring is fixed on the inner wall of the PE pipe body, a second ring groove is opened on the convex ring, a plurality of springs are fixed in the second ring groove, a sealing ring is fixed on the other end of the second spring, and a sealing ring is fixed on the piston.

[0016] With the above structure, by installing the spring 2, the sealing ring 4 is able to squeeze the sealing ring 3, so that the sealing ring 3 and the sealing ring 4 fit more closely, thereby improving the sealing effect.

[0017] Compared with the prior art, the detachable seal has the following advantages:

[0018] 1. Connect the sealing pipe to the outer wall of the PE pipe body through threads, and then drive the piston on the connecting rod to move by rotating the pull block. The piston moves to the inside of the PE pipe body to block and seal the outlet. Then fix the PE pipe body and the sealing pipe through a fixing mechanism, thereby improving the sealing performance of the sealing pipe to the PE pipe body.

[0019] 2. By installing the clamping column and the circular groove, the clamping column is driven to retract into the installation groove by sliding the slide bar. When the clamping block on the fixing rod is inserted into the groove, the slide bar is released. The elastic force of the spring causes the clamping column to bounce into the circular groove, thereby achieving a fixed connection between the PE pipe body and the sealing pipe and preventing the threaded connection from loosening.
