Description

Technical Field

[0001] This utility model relates to the field of pipeline elbow seal detection technology, specifically a pipeline elbow seal detection device. Background Technology

[0002] In piping systems, elbows are pipe fittings used to change the direction of pipes. Elbows are made of materials such as cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. Pipe elbows are a commonly used connecting fitting in pipe installation, connecting two pipes with the same or different nominal diameters to make a certain angle turn in the pipeline.

[0003] A related technology (publication number: CN221620446U) discloses an elbow bending production device. The disclosed technical solution is as follows: through the designed elbow bending production device, the first electric telescopic rod and the second electric telescopic rod synchronously drive the first movable clamping block and the second movable clamping block to move towards the first fixed clamping block and the second fixed clamping block to clamp and fix both ends of the iron pipe. The rotating motor is started to drive the movable plate to rotate, thereby driving the second movable clamping block and the second fixed clamping block to rotate and bend the iron pipe. The fixed length of the iron pipe bend is adjusted by the movement of the limiting plate outside the fixed rod according to the scale line. This effectively solves the problem that the size of one end of the elbow cannot be adjusted according to the required length in the traditional elbow bending production device, resulting in inconsistent length.

[0004] The above-disclosed technical solutions reveal the following problems: After the production of pipe elbows is completed, it is necessary to test the airtightness of the pipe elbows to ensure their quality. To address this, we propose a novel pipe elbow sealing testing device.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of pipe elbow sealing detection in the prior art, this utility model provides a pipe elbow sealing detection device, which combines a pipe elbow sealing detection mechanism with a pipe detection fixing mechanism to ensure the production quality of pipe elbows. Its specific technical solution is as follows:

[0007] A pipe elbow sealing testing device includes a testing tank, an immersion frame slidably disposed on the inner wall of the testing tank, a testing seat disposed on the top of the immersion frame, a locking component disposed on the immersion frame opposite to the testing seat, two ends of an air inlet pipe symmetrically embedded in the two outer walls of the testing tank, and both ends of the air inlet pipe extending into the inner cavity of the testing tank, an air pump disposed on the outer wall of the testing tank, and the output end of the air pump embedded in the outer wall of the air inlet pipe, and a lifting mechanism for picking up and placing the immersion frame disposed on the side wall of the testing tank.

[0008] In the above technical solution, the locking component includes a bracket fixed to the top of the immersion rack, and the bracket covers the outside of the detection seat. An electric telescopic component is embedded in the top of the bracket, and a locking component opposite to the detection seat is fixed to the movable end of the electric telescopic component.

[0009] The inner wall of the locking component is uniformly provided with anti-slip pads.

[0010] A flexible connecting pipe is fixed to the end of the air inlet pipe that extends into the inner cavity of the detection pool.

[0011] The top of the immersion rack has evenly spaced immersion holes.

[0012] The lifting mechanism includes a lead screw rotatably mounted on the side wall of the testing pool, and a lifting seat is externally threaded onto the lead screw. The lifting seat is connected to the immersion rack via a connecting frame.

[0013] The outer wall of the testing pool is provided with a guide rod parallel to the lead screw, and a guide seat is sleeved on the outer wall of the guide rod. The guide seat is connected to the immersion rack through a guide frame.

[0014] The inner wall of the detection pool is symmetrically fixedly equipped with guide columns. A limiting component is fixedly installed at the end of the guide column away from the inner wall of the detection pool. The side walls of the connecting frame and the guide frame are both provided with sliding grooves corresponding to the guide columns. The guide columns pass through the inner cavity of the sliding grooves.

[0015] A filter screen is embedded in the inner cavity of the detection pool.

[0016] The bottom of the detection pool is provided with a funnel-shaped bottom, and a drain port is embedded in the bottom of the funnel-shaped bottom, and a valve is provided on the drain port.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the pipe elbow sealing detection device:

[0018] 1. When inspecting pipe bends, place the center of the pipe bend on the inspection seat, and then fix the pipe bend with the locking component. This ensures the stability of the pipe bend inspection process, avoids positional deviation, and thus ensures the sealing of the pipe bend inspection process and the accuracy of the inspection results.

[0019] Second, the lifting mechanism drives the immersion frame to bring the two pipe elbows into the testing pool. Then, the condition of the pipe elbows in the liquid in the testing pool is observed. When bubbles appear in the testing pool, it proves that there is a sealing problem in the pipe elbows. This makes the operation of the pipe elbow testing process more convenient. Afterwards, the pipe elbows with sealing problems are treated to ensure the quality of the pipe elbows.

[0020] 3. When inspecting pipe elbows, place the center of the outer wall of the pipe elbow into the placement groove on the surface of the inspection seat. Then, use the movable end of the electric telescopic component to drive the arc-shaped locking component to move towards the pipe elbow, thereby fixing the pipe elbow on the inspection seat. Adjust the position of the locking component according to the specifications of the pipe elbow to make it suitable for fixing pipe elbows of different specifications.

[0021] Fourth, the four flexible connecting pipes are fixedly connected to both ends of the two pipe elbows to be tested by extending and deforming. The extension and deformation of the flexible connecting pipes makes it easier to connect the pipe elbows to the air inlet pipe, thereby ensuring the sealing of the connection between the air inlet pipe and the pipe elbow.

[0022] 5. When the fixed pipe elbow is immersed in the test tank, the output shaft of the motor drives the lead screw to rotate, so that the lifting seat connected to the external thread of the lead screw moves one side of the connecting frame through the connecting rod, so that the other side of the connecting frame is attached to the inner wall of the test tank and moves the immersion frame into the test tank, so that the immersion frame moves the surface-fixed pipe elbow into the liquid in the tank, making the operation process more convenient.

[0023] 6. During the process of rotating the lead screw to move the connecting frame and the immersion frame, the immersion frame simultaneously slides against the outer wall of the guide rod through the guide frame and the guide seat. The guide rod, which is parallel to the lead screw, ensures the stability of the immersion frame's movement direction and avoids positional deviation, thereby providing protection for the pipe bend connection.

[0024] 7. The guide columns on the inner walls of the two side detection pools ensure the stability of the moving direction of the connecting frame and the guide frame, thereby ensuring the stability of the moving direction of the immersion frame. Attached Figure Description

Detailed Implementation

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The following is a combination of specific implementation cases and attached Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0032] A pipe elbow sealing testing device includes a testing pool 1. An immersion frame 2 is slidably mounted on the inner wall of the testing pool 1, and a testing seat 3 is mounted on the top of the immersion frame 2. A locking component is mounted on the immersion frame 2 opposite to the testing seat 3. The length of the immersion frame 2 corresponds to the length of the testing pool 1, allowing the immersion frame 2 to slide against the inner wall of the testing pool 1. Two testing seats 3 are symmetrically and fixedly mounted on the top of the immersion frame 2. When testing the pipe elbow, the center position of the pipe elbow is placed on the testing seat 3, and then the pipe elbow is fixed by the locking component. This ensures the stability of the pipe elbow testing process, avoids positional displacement, and thus guarantees the sealing performance of the pipe elbow during testing, ensuring the accuracy of the test results.

[0033] The two ends of the air inlet pipes 4 are symmetrically embedded in the outer walls of both sides of the detection pool 1, and both ends of the air inlet pipes 4 extend into the inner cavity of the detection pool 1. The air inlet pipes 4 are fixedly installed on the surfaces of both sides of the detection pool 1, penetrating the side walls of the detection pool 1 and extending into the inner cavity of the detection pool 1. The outer wall of the air inlet pipes 4 near the port is fixedly embedded in the through hole of the detection pool 1. This ensures that the two air inlet pipes 4 are symmetrically fixedly installed on both sides of the detection pool 1. A fixing seat 15 is fixedly sleeved on the outer wall of the air inlet pipe 4 through a through hole in the center of the inner cavity, and the fixing seat 15 is fixedly installed on the outer wall of the detection pool 1 by a fixing rod. The two fixing seats 15 ensure the stability of the position of the air inlet pipes 4.

[0034] An air pump 6 is installed on the outer wall of the testing pool 1, with its output end embedded in the outer wall of the air inlet pipe 4. The air pump 6 is fixedly mounted on the outer wall of the testing pool 1 via a frame, and its position corresponds to the position of one of the air inlet pipes 4 on one side wall; that is, the air pump 6 is located below one of the air inlet pipes 4. The air pump 6 is electrically connected to an external power source via a wire. The output end of the air pump 6 is fixedly connected to one end of a right-angle tube, the other end of which is fixedly embedded in the outer wall of one of the air inlet pipes 4, allowing the gas output from the air pump 6 to enter the interior of one of the air inlet pipes 4. The two ends of the other air inlet pipe 4 on the other side are also embedded in the side wall of the testing pool 1, enabling the two air inlet pipes 4 on both sides to simultaneously test two pipe bends.

[0035] The side wall of the testing pool 1 is equipped with a lifting mechanism for placing and removing the immersion rack 2. This lifting mechanism causes the immersion rack 2 to move the fixed pipe bends. After the pipe bends are fixed to the immersion rack 2, the two ends of each pipe bend are connected to the two ends of each of the two air inlet pipes 4, thus forming a complete circuit between the two pipe bends to be tested and the two air inlet pipes 4.

[0036] Then, the lifting mechanism drives the immersion rack 2 to move the two pipe elbows into the testing tank 1, making the process of placing and removing the pipe elbows easier. Next, the air pump is connected to a power source, allowing gas to be pumped into one of the air inlet pipes 4. The condition of the pipe elbows in the liquid within the testing tank 1 is then observed. The appearance of bubbles in the testing tank 1 indicates a sealing problem in the pipe elbow. This process simplifies the pipe elbow testing process, allowing for the treatment of pipe elbows with sealing issues, thus ensuring the quality of the pipe elbows.

[0037] The locking assembly includes a bracket 11 fixed to the top of the immersion rack 2, which covers the outside of the detection seat 3. An electric telescopic component 10 is embedded in the top of the bracket 11, and a locking component 12 opposite to the detection seat 3 is fixedly connected to the movable end of the electric telescopic component 10. Two U-shaped brackets 11 are vertically fixed to the top of the immersion rack 2, and the brackets 11 are located above the detection seat 3. A through hole is longitudinally formed in the top of the bracket 11, penetrating the inner cavity, and the electric telescopic component 10 is fixedly embedded inside the through hole, positioned perpendicular to the top of the bracket 11. The electric telescopic component 10 can be a cylinder or an electric push rod. The electric telescopic component 10 is electrically connected to an external power source via a wire.

[0038] The movable end of the electric telescopic component 10 is vertically fixed to the top of the outer wall of the locking component 12. The locking component 12 is an arc-shaped plate. By setting it into an arc shape, the fit with the surface of the pipe elbow is improved, thereby ensuring the stability of the pipe elbow inspection process.

[0039] During pipe elbow inspection, the center of the outer wall of the pipe elbow is placed against the placement groove on the surface of the inspection seat 3. Then, the movable end of the electric telescopic component 10 drives the arc-shaped locking component 12 to move towards the pipe elbow. This causes the arc-shaped inner wall of the locking component 12 to fit snugly against the outer wall of the pipe elbow, thereby fixing the pipe elbow to the inspection seat 3. The position of the locking component 12 can be adjusted according to the specifications of the pipe elbow, thus making it suitable for fixing pipe elbows of different specifications.

[0040] It is worth noting that the inner wall of the locking component 12 is uniformly provided with anti-slip pads 13. The anti-slip pads 13 are made of elastic material, that is, rubber. The rubber anti-slip pads 13 increase the friction between the inner wall of the locking component 12 and the contact surface of the pipe elbow, thereby ensuring the stability of the pipe elbow detection and movement process.

[0041] In addition, flexible connecting pipes 5 are fixedly connected to the end of the air inlet pipe 4 extending into the inner cavity of the detection pool 1. Four flexible connecting pipes 5 are fixedly connected to one end of each of the four ends of the two air inlet pipes 4 via flanges. The other ends of the four flexible connecting pipes 5 are respectively extended and deformed to be fixedly connected to the two ends of the two pipe elbows to be tested. The extension and deformation of the flexible connecting pipes 5 makes the connection process between the pipe elbows and the air inlet pipes 4 more convenient, thereby ensuring the sealing of the connection between the air inlet pipes 4 and the pipe elbows.

[0042] In addition, immersion holes 19 are evenly distributed on the top of the immersion rack 2. Multiple parallel immersion holes 19 are horizontally distributed on the upper surface of the immersion rack 2, thereby reducing the resistance during the process of the immersion rack 2 entering the liquid in the detection pool 1.

[0043] Furthermore, the lifting mechanism includes a lead screw 21 rotatably mounted on the side wall of the testing pool 1. The lead screw 21 is externally threaded to a lifting seat 22, which is connected to the immersion rack 2 via a connecting frame 7. A first frame 20 is longitudinally and fixedly mounted on the outer wall of the testing pool 1. Bearings are embedded in the inner walls of both the upper and lower sides of the first frame 20. The two ends of the lead screw 21 are respectively embedded in the two bearings, allowing the lead screw 21 to rotate within the first frame 20.

[0044] The lifting seat 22 is connected to the lead screw 21 through a threaded through-hole in its inner cavity. A cover 25 is fixedly installed at the bottom of the first frame 20, and a motor 24 is fixedly embedded in the inner cavity of the cover 25. The output shaft of the motor 24 passes through the bottom of the first frame 20 and is fixedly connected to the end of the lead screw 21. The motor 24 is electrically connected to an external power source through wires. One side of the U-shaped connecting frame 7 slides against the inner wall of the detection pool 1 and is vertically fixed to the top edge of the immersion rack 2. The other end of the U-shaped connecting frame 7 covers the outside of the first frame 20. The connecting frame 7 and the lifting seat 22 are fixedly connected by a connecting rod 16.

[0045] When the fixed pipe elbow is immersed in the test pool 1, the motor 24 is connected to the power supply, so that the output shaft of the motor 24 drives the lead screw 21 to rotate. This causes the lifting seat 22, which is externally threaded to the lead screw 21, to move one side of the connecting frame 7 through the connecting rod 16, so that the other side of the connecting frame 7 is in contact with the inner wall of the test pool 1 and moves the immersion frame 2 into the test pool 1. This allows the immersion frame 2 to immerse the surface-fixed pipe elbow into the liquid in the pool, making the operation more convenient.

[0046] A guide rod 28, parallel to the lead screw 21, is provided on the outer wall of the testing pool 1. A guide seat 26 is sleeved on the outer wall of the guide rod 28, and the guide seat 26 is connected to the immersion rack 2 via a guide frame 30. One side of the U-shaped guide frame 30 slides against the inner wall of the testing pool 1, and the other side of the guide frame 30 is fixedly connected to the guide rod 28 via a support rod 23. A second frame 27 is fixedly mounted on the surface of the testing pool 1 on the side opposite to the first frame 20, with both ends of the guide rod 28 vertically fixed to the inner walls of the upper and lower sides of the second frame 27, respectively. The guide seat 26 is movably sleeved on the outside of the guide rod 28 through a longitudinally opened through hole.

[0047] As the screw 21 rotates, causing the connecting frame 7 to move the immersion frame 2, the immersion frame 2 simultaneously slides against the outer wall of the guide rod 28 via the guide frame 30 and the guide seat 26. The guide rod 28, which is parallel to the screw 21, ensures the stability of the immersion frame 2's movement direction and prevents positional deviation, thereby providing protection for the pipe bend connection.

[0048] Guide columns 18 are symmetrically fixedly installed on the inner wall of the testing pool 1, and a limiting component is fixedly installed at the end of the guide column 18 away from the inner wall of the testing pool 1. Slide grooves 14 corresponding to the guide columns 18 are opened on the side walls of both the connecting frame 7 and the guide frame 30, and the guide columns 18 penetrate the inner cavity of the slide grooves 14. The limiting components 9 on both sides slide against the surfaces of the connecting frame 7 and the guide frame 30 respectively. The guide columns 18 on the inner walls of the testing pool 1 on both sides ensure the stability of the moving direction of the connecting frame 7 and the guide frame 30, thereby ensuring the stability of the moving direction of the immersion rack 2.

[0049] A filter screen 17 is embedded in the inner cavity of the detection tank 1. The liquid discharged from the detection tank 1 is filtered through the filter screen 17.

[0050] The bottom of the testing tank 1 is provided with a funnel-shaped bottom, and a drain port 8 is embedded in the bottom of the funnel-shaped bottom. A valve is provided on the drain port 8. The funnel-shaped bottom is fixedly connected to the bottom of the testing tank 1, and the drain port 8 is fixedly embedded in the bottom of the funnel-shaped bottom. The opening and closing of the drain port 8 is controlled by the valve. The funnel-shaped bottom avoids the accumulation of liquid during the discharge process, thereby facilitating the operation of the discharge process.

[0051] This embodiment discloses a pipe elbow sealing detection device. The working principle is as follows: First, the center position of the outer wall of the pipe elbow is attached to the placement groove on the surface of the detection seat 3. Then, the movable end of the electric telescopic component 10 drives the arc-shaped locking component 12 to move towards the pipe elbow, so that the arc-shaped inner wall of the locking component 12 fits and snaps against the outer wall of the pipe elbow, thereby fixing the pipe elbow on the detection seat 3.

[0052] Then, through the extension and deformation of the four flexible connecting tubes 5, the two ends of the pipe elbows to be tested are respectively connected to the ends of the four flexible connecting tubes 5. Then, the motor 24 is connected to the power supply, so that the output shaft of the motor 24 drives the lead screw 21 to rotate, so that the lifting seat 22 connected to the external thread of the lead screw 21 drives one side of the connecting frame 7 to move through the connecting rod 16. So that the other side of the connecting frame 7 is attached to the inner wall of the test pool 1 and drives the immersion frame 2 to move into the test pool 1, so that the immersion frame 2 drives the surface-fixed pipe elbow to be immersed in the liquid in the pool.

[0053] Next, connect the air pump to the power supply, allowing it to input gas into one of the air inlet pipes 4. Then, observe the situation of the pipe elbow in the liquid within the test tank 1. When bubbles appear in the test tank 1, it indicates a sealing problem with the pipe elbow.
