Description

Embedded water test leak test tube plug

The present invention relates to a plug-in plug for a buried water test leak detector.

In current buildings, water pipe lines are often arranged in the building structure, such as embedded in walls, ceilings or beams. However, these water pipes usually have multiple bending points, so they must be connected by most L-type joints, ordinary joints or T-type joints. In order to ensure that the water pipe lines are connected properly, after the completion of the pipe connection operation, leak detection must be performed and checked. After the core is indeed leak-free, it is embedded in the building structure. In addition, in order to connect these pipelines embedded in the structure in the future, joints will be embedded in the pipeline to meet the needs.

As shown in Figs. 1 and 2, in a conventional water-testing and leak-testing component of an embedded pipeline, a first joint (30) having a threaded hole (31) at one end is used, and the first joint (30) is another The end (32) is connected to the end outlet of the pipeline (P). Because the first joint (30) with threaded holes (31) in the system, such as an elbow, is not high enough to lay reinforcement (S), it is necessary to lock one The second joint (40) of the external thread (41) and the internally threaded hole (42) is elevated, and then a block (50) is locked to the end of the internally threaded hole (42) of the second joint (40). In order to close the outlet at the end of the pipeline (P), a leak test can be performed at this time. After the test is completed and the pipeline (P) is confirmed to be leak-free, the blocked (50) end can be fixed to the grout of the formwork (M). After the concrete is hardened and demolished, the block (50) can be exposed to the surface of the building, as shown in Figure 3, for future use in connecting other pipelines.

When other pipelines need to be connected to the pipeline (P) embedded in the building, as shown by the imaginary line in FIG. 3, the blocking (50) can be turned back, and then as shown in FIG. 4, the second joint is borrowed. The female screw hole (42) of (40) is locked with a third joint (60), and then the third joint (60) is used to connect the pipe fittings (P ') outside the building structure.

The above-mentioned conventional application is applied to the leak test component of the embedded pipeline. The required components must contain three components, namely the first and second joints (30, 40) and the block (50). The first and second joints (30, 40) and the block (50) are wound around the belt and tightened. For a single construction project, there may be dozens or even hundreds of construction points, so the above-mentioned conventional method Will increase the cost, and is very time-consuming and labor-intensive in construction, and there is a need for improvement.

In addition, the above-mentioned practice is applied to the embedded pipeline water test and leak detection assembly. Since the first and second joints (30, 40) are connected by threads, although a leak-proof band will be wound during locking, but After long-term frequent vibrations (such as earthquakes) or aging of the anti-leakage band, it is easy to loosen the thread joint and cause water leakage. Because it is buried in the building, once the water leakage occurs, it is very difficult to repair it, which is obvious. Disadvantages, and there is a need for improvement.

In view of this, the new creator of this case has researched it and finally revealed a plug-in plug for a water test leak test tube.
