Description

Technical Field

[0001] This utility model relates to the field of pipe testing devices, and in particular to a rigid polyvinyl chloride pipe testing device. Background Technology

[0002] A rigid PVC pipe testing device is a specialized instrument used to test and evaluate the performance and quality of rigid PVC pipes. Rigid PVC pipes are widely used in construction, water supply and drainage, sewage, ventilation and other fields, so ensuring their quality and performance is crucial. The testing device typically includes a hydrostatic testing machine to perform pressure tests on the pipes and check for liquid leaks.

[0003] In existing technologies, some rigid PVC pipe testing devices fill the test chamber with liquid to ensure it is completely full, thus detecting whether the pipe is leaking. After the liquid is emptied, air is extracted from the pipe, pressure is applied, and the pipe's pressure resistance is tested. However, in some rigid PVC pipe testing devices, during the fixing and connection of the pipe, the interface between the pipe and the testing device may not be completely sealed, leading to leaks and causing errors in the test data. Utility Model Content

[0004] This utility model proposes a rigid polyvinyl chloride (PVC) pipe testing device, which aims to improve upon some existing rigid PVC pipe testing devices, which suffer from leakage at the interface during fixing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A testing device for rigid polyvinyl chloride (PVC) pipes includes a testing chamber. A sliding connector is slidably connected to the inner wall of one side of the testing chamber. An elastic telescopic rod is fixedly connected to the outside of the sliding connector. A limiting connecting ring is fixedly connected to one end of the elastic telescopic rod. A bolt is threadedly connected to the inner wall of the sliding connector. A nut rod is fixedly connected to the outside of the limiting connecting ring. A sliding assembly for sliding is fixedly connected to the outside of one side of the testing chamber. A double-layer water-blocking cover is fixedly connected to the bottom of the sliding assembly. A bolt is threadedly connected to the inner wall of the outer side of the double-layer water-blocking cover. A threaded groove is formed on the outside of the sliding connector. A limiting sliding block is fixedly connected to the outside of the testing chamber.

[0006] The testing chamber is used to house the pipe, providing a safe environment for testing. The sliding connector is then aligned with one end of the fixed pipe. Tightening the bolts secures the sliding connector, preventing movement and ensuring a stable connection. A sliding assembly allows the double-layered water-blocking cover to fit snugly against the sliding connector, preventing leaks during testing. Moving the double-layered water-blocking cover, using the limiting sliding block, drains the testing liquid from the pipe.

[0007] As a further description of the above technical solution: The sliding assembly includes a sliding groove plate, and a sliding connecting rod is slidably connected to the inner wall of the sliding groove plate. One end of the sliding groove plate is fixedly connected to the outside of the detection box.

[0008] The second sliding connecting rod slides on the inner wall of the first sliding plate, causing the connected part of the device to move.

[0009] As a further description of the above technical solution: A support rod is fixedly connected to the bottom inner wall of the detection box. A fixed semi-circular ring is fixedly connected to one end of the support rod. A rotating component for rotating opening and locking is rotatably connected inside the fixed semi-circular ring.

[0010] Support rod one is used to support the pipe placed on fixed semi-circular ring one to ensure its horizontal position, and rotating assembly causes the connected device to rotate.

[0011] As a further description of the above technical solution: The top inner wall of the detection box is provided with a sliding groove 2, and a sliding connecting rod 3 is slidably connected to the top inner wall of the detection box. A support rod 2 is fixedly connected to the bottom of the sliding connecting rod 3, and a fixed semi-circular ring 2 is fixedly connected to the bottom of the support rod 2.

[0012] The sliding connecting rod three slides in the sliding groove two opened in the detection box, driving the support rod two to slide, and abutting against the fixed semi-circular ring two in conjunction with the fixed semi-circular ring one to lock the pipe and prevent it from moving during the detection.

[0013] As a further description of the above technical solution: The sliding assembly includes a first rotating shaft, one end of which is fixedly connected to a receiving block, and a second rotating shaft is fixedly connected to the inner wall of the receiving block. The first rotating shaft is slidably connected to the inner wall of the first fixed semicircular ring.

[0014] The receiving block connects rotating shaft one to rotating shaft two, activating the hinge effect and causing the connected device to rotate.

[0015] As a further description of the above technical solution: The inner wall of one side of the detection chamber is fixedly connected to a second interface, and the inner wall of one side of the detection chamber is fixedly connected to a pressure boosting pipe.

[0016] Interface two is used to connect with the pipe, keeping it horizontal and fixed. Liquid is injected into the pipe to detect leaks, while air is extracted to test the pipe's pressure resistance. The pressure booster pipe is used to pressurize the inside of the testing chamber to test the pressure resistance of the pipe's outer wall.

[0017] As a further description of the above technical solution: A hydrostatic testing device is fixedly connected to the left side of the testing chamber. A hinge is fixedly connected to the outside of the testing chamber. A sealing door is fixedly connected to the bottom of one side of the hinge. A locking block is fixedly connected to the outside of one side of the sealing door.

[0018] The hydrostatic testing device is used to test rigid PVC pipes. The hinge allows the sealing door to rotate, which is used to open and close the sealing door.

[0019] As a further description of the above technical solution: A second locking block is fixedly connected to the outside of one side of the detection box, and a pin is slidably connected to the inner wall of the second locking block.

[0020] Block 1 and Block 2 are connected to the sealing door and the detection chamber, respectively. When the sealing door is closed, a pin is inserted to prevent leakage during detection.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when testing rigid polyvinyl chloride pipes, one end of the pipe is inserted into the second connector, and the sliding connector is pushed into the other end of the pipe. The bolt is tightened to fix the sliding connector and the test box together. The sliding double-layer cover is inserted into the sliding connector to block it, which facilitates the fixing of the pipe. At the same time, the input of liquid into the pipe and the increase of the internal pressure of the pipe will not cause leakage, thus preventing data errors in the pipe test.

[0022] 2. In this utility model, the pipe is placed inside the testing chamber and placed on the fixed semi-circular ring one. After docking, the fixed semi-circular ring two is rotated to fix the pipe. The sliding support rod two is slid to the fixed semi-circular ring two and stops through the sliding connecting rod three. The support rod two cooperates with the support rod one to hold the pipe in place, thereby preventing the pipe from moving during the pressure test and causing leakage. Attached Figure Description

The external side of the sliding connecting pipe port 2 has a threaded groove 11. The external fixed connection of the detection box 1 is a limiting water-sliding block 12, which is used to keep the sliding connecting pipe port 2 sliding horizontally and guide the liquid used for testing to drain.

[0027] Reference Figure 3 , Figure 4A support rod 13 is fixedly connected to the inner wall of the bottom of the testing chamber 1. A fixed semi-circular ring 14 is fixedly connected to one end of the support rod 13. The pipe is placed on the fixed semi-circular ring 14 and supported by the support rod 13 to maintain a horizontal position. A rotating shaft 15 for opening and locking is rotatably connected inside the fixed semi-circular ring 14. A receiving block 16 is fixedly connected to one end of the rotating shaft 15. A second rotating shaft 17 is fixedly connected to the inner wall of the receiving block 16, achieving a hinge effect. This allows the second fixed semi-circular ring 18 and the fixed semi-circular ring 14 to be rotatably connected. When the pipe is placed on the fixed semi-circular ring 14, the rotation... The fixed semicircular ring 18 secures the pipe. The top inner wall of the testing chamber 1 has a sliding groove 19.

[0029] Working Principle: First, the pin 29 is pulled out from the locking blocks 28 and 27, the sealing door 26 is opened, and the rigid PVC pipe to be tested is placed into the interface 22 for testing. The pipe is placed on the fixed semi-circular ring 14, which acts like a hinge through the receiving block 16, allowing the fixed semi-circular rings 14 and 2 to rotate. Rotating the fixed semi-circular ring 18 locks it in place, and the sliding support rod 21, in conjunction with the support rod 13, fixes the pipe in place, preventing it from moving during testing and affecting the test data. Liquid is introduced into the pipe through the interface 22 for observation to detect leaks, or gas is extracted from the pipe to increase the internal pressure and test the pressure resistance of the inner wall. The pressure boosting pipe 23 can extract air from the test chamber 1 to increase the internal pressure and test the pressure resistance of the outer wall of the pipe.

[0030] Then, before testing, slide the sliding connector 12 to the testing chamber 1 and tighten bolt 15 to fix it in a horizontal position. At the same time, slide the double-layer water-blocking cover 9 to fit the sliding connector 12 and tighten bolt 210 to fix it in place, blocking the sliding connector 12 to prevent leakage during testing and affecting the test data. After testing, open the double-layer water-blocking cover 9 and guide the liquid out through the limiting sliding block 12.
