[0001] The utility model relates to the technical field of building decoration, in particular to a waterproof sealing structure of an inner thread elbow of a water supply pipeline concealedly laid in a wall. Background Art
[0002] Nowadays, water-using appliance areas such as water rooms or toilets are often connected to the connection points where the inner thread elbows of the water supply pipes are concealed in the wall and the control valves are installed. If the anti-leakage measures are not appropriate, water seepage and moisture return are very likely to occur. Therefore, the walls in the area where the water-using appliances are connected are very likely to be damp due to moisture, and the non-block decorative surface layer on the back wall will be moldy and damaged. After sufficient research and analysis, it was found that the main reason for the above phenomenon is that the tightening connection operation between the angle valve and the inner thread elbow of the water supply pipe is not standardized, causing cracks and penetration damage to the copper inserts of the inner thread elbow or not tightening tightly, resulting in water leakage from the inner thread elbow. Since the outlet plane of the inner thread elbow of the water supply pipe concealed in the wall is lower than the block decorative surface layer, the leaking water can easily penetrate into the gap between the inner thread elbow outlet surface and the block decorative surface layer into the filling area around the inner thread elbow body, so the inner thread elbow The gap between the outlet surface and the block decorative surface layer is the main channel for water seepage. Since the mortar filling in the groove filling area around the female elbow body is not dense and the waterproof layer is not covered in place, the seeping water will continue to penetrate inward along the groove filling mortar around the female elbow body to the pipe groove wall area. The generated moisture will continue to slowly diffuse to the back wall. Therefore, the non-block decorative surface layer on the back wall is in a humid environment for a long time, which can easily lead to mildew and damage of the non-block decorative surface layer on the back wall.
[0003] Therefore, how to solve the problem of water leakage at the internal thread elbow, moisture in the wall, and mildew and damage of the non-block decorative surface on the back wall due to improper installation and tightening operation of the angle valve, resulting in cracks and penetration damage in the copper insert of the internal thread elbow or failure to tighten tightly, has become an urgent problem to be solved by people today.
