Description

Technical Field

[0001] The utility model relates to a pre-buried pipeline, in particular to a high-stability pre-buried pipeline. Background Art

[0002] At present, in building installation projects, many pipes need to be installed that need to pass through wall panels or floor slabs, some of which need to be leak-proof, such as pipes in bathrooms and roofs. This requires placing embedded pipes when pouring concrete to avoid leakage due to lax sealing, which may cause subsequent losses. However, despite the use of embedded pipes, leakage is prone to occur. For example, when the amount of water flowing inside the embedded pipe is large, water easily overflows and penetrates into the lower layer from the gap between the embedded pipe and the lower pipe, which leads to a decrease in the stability of the pipe itself and causes leakage accidents. Therefore, how to achieve a high-stability embedded pipe that can prevent leakage and thus improve the stability of the pipe during use has become an urgent problem to be solved.

The pipeline body includes an inner tube for transporting liquid and an outer tube covering the outer wall of the inner tube, so as to prevent the transported liquid inside the pipeline body from leaking to the external environment when any pipeline between the inner tube or the outer tube is broken.

[0006] Furthermore, a partition plate is connected between the outer tube and the inner tube, and the partition plate separates the outer tube and the inner tube into an isolation cavity, and the isolation cavity is used to prevent the transported liquid inside the pipeline body from leaking to the external environment when any pipeline between the inner tube or the outer tube is broken.

[0011] Furthermore, the connecting valve comprises a rotating handle, a valve body and a conducting column;

[0012] The pipeline body is fixed on both sides of the valve body by the fixing ring, the inner tube and the isolation cavity are respectively communicated with the left chamber and the right chamber in the valve body, one end of the conducting column is inserted into the valve body and isolates the left chamber and the right chamber, a plurality of conducting openings are penetrated through the middle of the conducting column, and the rotating handle is arranged at the other end of the conducting column, so that the conducting column is driven to rotate by external force. When the conducting column rotates to a set angle, the left chamber and the right chamber can be communicated through the conducting openings, so as to realize the opening of the connecting valve.

[0013] Furthermore, the connector also includes a testing component, and the pipe body is also provided with a testing opening;

[0014] The test opening is arranged on the outer tube and is connected with the isolation cavity.

[0015] Furthermore, a pressure gauge is connected to the conducting tube, so as to realize real-time observation of the air pressure in the isolation cavity and achieve the effect of air leakage observation.

[0016] Furthermore, a second one-way valve is provided on the test opening to prevent leakage of gas in the isolation cavity.

This solves the problem in the prior art that when the amount of water flowing inside the embedded pipe is large, water easily overflows and penetrates into the lower layer from the gap between the embedded pipe and the lower pipe, resulting in a decrease in the stability of the pipeline itself and the occurrence of leakage accidents, thereby improving the stability of the pipeline when in use.
