In the sealing connecting pipe, the outer side wall of the first connecting cylinder is provided with a first external thread, the outer side wall of the second connecting cylinder is provided with a second external thread, the inner side wall of the first end of the inner pipe is provided with a first internal thread, and the inner side wall of the second end of the inner pipe is provided with a second internal thread.
In the sealing connecting pipe, the first flange plate is provided with at least three first fixing holes, and the second flange plate is provided with at least three second fixing holes.
In the sealing connecting pipe, a first sealing washer is sleeved outside the first connecting cylinder on the inner side surface of the first flange, and a second sealing washer is sleeved outside the second connecting cylinder on the inner side surface of the second flange.
In the sealing connecting pipe, the first flange plate is provided with a first annular groove for the first sealing washer to be embedded and connected, and the second flange plate is provided with a second annular groove for the second sealing washer to be embedded and connected.
In the sealing connecting pipe, the inner pipe and the outer pipe are both plastic pipes, and the buffer pipe is a rubber pipe.
The sealing connecting pipe has the following beneficial effects: when the sealing connecting pipe is used, when water flows through the inner pipe, if the inner pipe is impacted and expands outwards, the buffer pipe can play a certain role in buffering, and the inner pipe is prevented from cracking. Furthermore, when the connecting pipe is connected with other connecting pipes, the first flange plate or the second flange plate can be fixedly and hermetically connected with the flange plates of other connecting pipes, so that quick sealing connection is realized.
