Description

Technical Field

[0001] This utility model relates to the field of water system adapters, specifically a quick-connect adapter for pressure testing of a new house's water system. Background Technology

[0002] Water system pressure testing is typically conducted after all main, branch, and riser pipes have been installed. Before the test, pre-reserved openings must be sealed, the main inlet valve and drain valve closed, and the main valves of each branch line and the vent valve at the highest point of the system opened. Water is slowly introduced into the system through the water source valve to expel air from the pipes, then the valve is closed. A pressure booster pump is then used to slowly increase the pressure to the test pressure for monitoring and inspection. The water system pressure test adapter is a component used to connect the pipes to the pressure testing equipment during the water pressure test. Its function is to ensure that the water system can stably and accurately transmit pressure signals during the test and to ensure the sealing of the connections.

[0003] During water system pressure testing, adapters are mainly used to connect pressure testing equipment (such as pressure gauges, pressure testing pumps, etc.) to the pipeline being tested. However, traditional adapters are connected by bolts, and tools are needed to disassemble and reassemble the adapters, which takes a long time and reduces the efficiency of adapter assembly and disassembly.

[0004] Therefore, a quick-connect adapter for pressure testing of the water system in a new house is proposed to address the above issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a quick connection adapter for pressure testing of a new house water system.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The quick-connect adapter for pressure testing of the new house water system of this utility model includes a first adapter pipe; a second adapter pipe is slidably connected to the side of the first adapter pipe; a first limiting ring is fixedly connected to the side of the first adapter pipe; an L-shaped limiting block is fixedly connected to the side of the first limiting ring; an annular limiting groove is opened on the side of the second adapter pipe; an L-shaped limiting groove is opened on the side of the annular limiting groove; the first limiting ring is slidably connected to the annular limiting groove; the L-shaped limiting block is slidably connected to the L-shaped limiting groove; a connecting piece is fixedly connected to the surface of the first adapter pipe; a limiting groove is opened inside the connecting piece; a connecting pipe is slidably connected to the surface of the second adapter pipe; the connecting... A limiting block is fixedly connected to the side of the tube, and the limiting block is slidably connected to the limiting groove. This step reinforces the connection between the first and second adapter tubes by inserting the first limiting ring into the annular limiting groove. By inserting the L-shaped limiting block into the inner side of the L-shaped limiting groove and rotating it, the first and second adapter tubes can be connected to prevent them from separating. By moving the connecting tube, the limiting block can be driven into the limiting groove to reinforce the second adapter tube and prevent it from rotating on its own, which would cause the connection between the L-shaped limiting block and the L-shaped limiting groove to be unstable. This structure can separate the first and second adapter tubes by pulling the connecting tube and then rotating the first adapter tube, achieving the effect of quickly connecting and separating the first and second adapter tubes.

[0007] Preferably, a telescopic rod is fixedly connected to the surface of the second adapter pipe, and a spring is provided inside the telescopic rod. A movable ring is fixedly connected to one end of the telescopic rod, and the side of the movable ring is fixedly connected to the connecting pipe. This step can increase the stability of the connecting pipe moving on the surface of the second adapter pipe, and the spring inside the telescopic rod can push the movable ring to drive the connecting pipe to reset, increasing the stability of the connecting pipe pushing the limiting block into the limiting groove.

[0008] Preferably, a first sealing ring is fixedly connected to the inner side of the first adapter pipe, and a second sealing ring is fixedly connected to the inner side of the second adapter pipe, with the second sealing ring slidably connected to the first sealing ring; this step, through the connection of the first sealing ring and the second sealing ring, can increase the sealing stability at the connection between the first adapter pipe and the second adapter pipe.

[0009] Preferably, a filter screen is slidably connected to the inner side of the first adapter pipe, and a connecting bolt is threadedly connected to the inner side of the first adapter pipe. The connecting bolt is threadedly connected to the filter screen. In this step, the filter screen can filter the water flow passing through the first adapter pipe, the connecting bolt increases the stability of the filter screen, and the filter screen can be disassembled by separating the connecting bolt from the filter screen.

[0010] Preferably, a rotating block is fixedly connected to the surface of the moving ring, and there are several rotating blocks. A pull rod is fixedly connected to the side of the filter screen. Anti-slip pads are provided on the surfaces of the rotating blocks and the pull rod. This step, by setting several rotating blocks, makes it easier for the operator to pull the moving ring. At the same time, rotating the rotating blocks can drive the moving ring to rotate, making it easier to drive the second connecting pipe to rotate, reducing the time to separate the second connecting pipe from the first connecting pipe. The pull rod makes it easy to remove and replace the filter screen.

[0011] Preferably, a sealing ring is fixedly connected to the surface of the first adapter pipe, and the connecting bolt is threadedly connected to the sealing ring; in this step, the sealing ring can seal the connection between the connecting bolt and the first adapter pipe to prevent water leakage at the connection.

[0012] The advantages of this utility model are:

[0013] 1. The quick-connect adapter for pressure testing of the new house water system described in this utility model can reinforce the connection between the first adapter pipe and the second adapter pipe by inserting the first limiting ring into the annular limiting groove. By inserting the L-shaped limiting block into the inner side of the L-shaped limiting groove and rotating it, the first adapter pipe and the second adapter pipe can be connected to prevent them from separating. By moving the connecting pipe, the limiting block can be driven into the limiting groove to reinforce the second adapter pipe and prevent it from rotating on its own, which would cause the connection between the L-shaped limiting block and the L-shaped limiting groove to be unstable. This structure can separate the first adapter pipe and the second adapter pipe by pulling the connecting pipe and then rotating the first adapter pipe, thus achieving the effect of quickly connecting and separating the first adapter pipe and the second adapter pipe.

The quick-connect adapter for pressure testing of the new house water system described in this utility model can increase the stability of the connecting pipe moving on the surface of the second adapter pipe through the telescopic rod and the moving ring. In addition, the spring inside the telescopic rod can push the moving ring to drive the connecting pipe to reset, increasing the stability of the connecting pipe pushing the limiting block into the limiting groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, the quick-connect adapter for pressure testing of the new house water system includes a first adapter pipe 1; a second adapter pipe 12 is slidably connected to the side of the first adapter pipe 1; a first limiting ring 13 is fixedly connected to the side of the first adapter pipe 1; an L-shaped limiting block 14 is fixedly connected to the side of the first limiting ring 13; an annular limiting groove 15 is formed on the side of the second adapter pipe 12; an L-shaped limiting groove 16 is formed on the side of the annular limiting groove 15; the first limiting ring 13 is slidably connected to the annular limiting groove 15; the L-shaped limiting block 14 is slidably connected to the L-shaped limiting groove 16; a connecting piece 17 is fixedly connected to the surface of the first adapter pipe 1; and a limiting groove 17 is formed inside the connecting piece 17. The first adapter 12 is slidably connected to the surface of the second adapter 12, and a limiting block 110 is fixedly connected to the side of the connecting pipe 19. The limiting block 110 is slidably connected to the limiting groove 18. During operation, when the first adapter 1 and the second adapter 12 are connected, the connecting pipe 19 is located outside the connection point between the first adapter 1 and the second adapter 12. When it is necessary to separate the first adapter 1 and the second adapter 12, the connecting pipe 19 is pulled to one side, and the connecting pipe 19 moves horizontally on the surface of the second adapter 12, causing it to drive the limiting block 110 to separate from the limiting groove 18. Then the first adapter 1 can be rotated, which drives the first limiting ring. Rotation 13 causes the L-shaped limiting block 14 to rotate via the first limiting ring 13. This rotation separates the side of the L-shaped limiting block 14 from the groove on the side of the L-shaped limiting groove 16. Then, the first connecting pipe 1 and the second connecting pipe 12 can be pulled to move. The first connecting pipe 1 causes the first limiting ring 13 to separate from the annular limiting groove 15, and the first limiting ring 13 causes the L-shaped limiting block 14 to separate from the L-shaped limiting groove 16, thus separating the first connecting pipe 1 and the second connecting pipe 12. This step, by inserting the first limiting ring 13 into the annular limiting groove 15, reinforces the connection between the first connecting pipe 1 and the second connecting pipe 12. The L-shaped limiting block 14 can be inserted into the inner side of the L-shaped limiting groove 16 and rotated to connect the first adapter pipe 1 and the second adapter pipe 12, preventing them from separating. By moving the connecting pipe 19, the limiting block 110 can be inserted into the limiting groove 18 to reinforce the second adapter pipe 12 and prevent it from rotating, which would cause the connection between the L-shaped limiting block 14 and the L-shaped limiting groove 16 to be unstable. This structure can separate the first adapter pipe 1 and the second adapter pipe 12 by pulling the connecting pipe 19 and then rotating the first adapter pipe 1, achieving the effect of quickly connecting and separating the first adapter pipe 1 and the second adapter pipe 12.

[0024] like Figures 1 to 3As shown, a telescopic rod 21 is fixedly connected to the surface of the second adapter pipe 12. A spring is installed inside the telescopic rod 21. A movable ring 22 is fixedly connected to one end of the telescopic rod 21. The side of the movable ring 22 is fixedly connected to the connecting pipe 19. During operation, when the connecting pipe 19 is moved, the connecting pipe 19 drives the movable ring 22 to move. The movable ring 22 pushes the telescopic rod 21, and the spring inside the telescopic rod 21 pushes the movable ring 22 to reset. This step increases the stability of the moving of the connecting pipe 19 on the surface of the second adapter pipe 12. In addition, the spring inside the telescopic rod 21 can push the movable ring 22 to reset the connecting pipe 19, increasing the stability of the connecting pipe 19 pushing the limiting block 110 into the limiting groove 18.

[0025] like Figure 2 and Figure 3 As shown, a first sealing ring 31 is fixedly connected to the inner side of the first adapter pipe 1, and a second sealing ring 32 is fixedly connected to the inner side of the second adapter pipe 12. The second sealing ring 32 is slidably connected to the first sealing ring 31. During operation, when the first adapter pipe 1 and the second adapter pipe 12 are connected, the second adapter pipe 12 drives the inner second sealing ring 32 to move and insert into the interior of the first sealing ring 31. This step, through the connection of the first sealing ring 31 and the second sealing ring 32, can increase the sealing stability of the connection between the first adapter pipe 1 and the second adapter pipe 12.

[0026] like Figure 1 and Figure 2 As shown, a filter screen 41 is slidably connected to the inner side of the first adapter pipe 1, and a connecting bolt 42 is threadedly connected to the inside of the first adapter pipe 1. The connecting bolt 42 is threadedly connected to the filter screen 41. During operation, the filter screen 41 can filter the water flow passing through the first adapter pipe 1. By rotating the connecting bolt 42 to separate it from the filter screen 41, the filter screen 41 can be disassembled and installed. In this step, the filter screen 41 can filter the water flow passing through the first adapter pipe 1. The connecting bolt 42 increases the stability of the filter screen 41. By separating the connecting bolt 42 from the filter screen 41, the filter screen 41 can be disassembled and installed.

[0027] like Figures 1 to 5As shown, a rotating block 51 is fixedly connected to the surface of the moving ring 22, and there are several rotating blocks 51. A pull rod 52 is fixedly connected to the side of the filter screen 41. The surfaces of the rotating blocks 51 and the pull rod 52 are provided with anti-slip pads. During operation, the operator can pull the moving ring 22 to one side by rotating the rotating blocks 51. By rotating the rotating blocks 51, the moving ring 22 can be rotated, causing the second transfer tube 12 to rotate. This step, by setting several rotating blocks 51, makes it easier for the operator to pull the moving ring 22 to move. At the same time, by rotating the rotating blocks 51, the moving ring 22 can be rotated, making it easier to rotate the second transfer tube 12, reducing the time required to separate the second transfer tube 12 from the first transfer tube 1. The pull rod 52 makes it easy to remove and replace the filter screen 41.

[0028] like Figures 1 to 3 As shown, a sealing ring 61 is fixedly connected to the surface of the first adapter pipe 1, and the connecting bolt 42 is threadedly connected to the sealing ring 61; in this step, the sealing ring 61 can seal the connection between the connecting bolt 42 and the first adapter pipe 1 to prevent water leakage at the connection.

[0029] Working principle: When it is necessary to separate the first adapter pipe 1 from the second adapter pipe 12, the operator can pull the moving ring 22 to one side using the rotating block 51. Rotating the rotating block 51 will cause the moving ring 22 to rotate, making the second adapter pipe 12 rotate and pulling the connecting pipe 19 to one side. The connecting pipe 19 will translate on the surface of the second adapter pipe 12, causing it to separate the limiting block 110 from the limiting groove 18. Then, the first adapter pipe 1 can be rotated, which will cause the first limiting ring 13 to rotate. The first limiting ring 13 will cause the L-shaped limiting block 14 to rotate. The rotation of the L-shaped limiting block 14 will cause its side to separate from the groove on the side of the L-shaped limiting groove 16. Then, the first adapter pipe 1 and the second adapter pipe 12 can be pulled apart. The second adapter pipe 12 moves, causing the first limiting ring 13 to separate from the annular limiting groove 15 via the first adapter pipe 1. The first limiting ring 13 causes the L-shaped limiting block 14 to separate from the L-shaped limiting groove 16, thus separating the first adapter pipe 1 from the second adapter pipe 12. When the connecting pipe 19 is moved, the connecting pipe 19 causes the moving ring 22 to move, which pushes the telescopic rod 21. The spring inside the telescopic rod 21 pushes the moving ring 22 to reset. When the first adapter pipe 1 is connected to the second adapter pipe 12, the second adapter pipe 12 causes the inner second sealing ring 32 to move and insert into the interior of the first sealing ring 31. The connecting bolt 42 is rotated to separate it from the filter screen 41, allowing the filter screen 41 to be disassembled and assembled.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
