Description
Technical Field
[0001] This utility model belongs to the field of pipe fitting testing technology, specifically a pressure resistance test bench for PVC pipes. Background Technology
[0002] A pipe pressure tester is a device specifically designed to evaluate the pressure resistance of pipes under specific conditions. This test typically involves placing the pipe in a high-pressure environment to simulate the pressure conditions it might encounter in real-world applications.
[0003] For PVC pipe pressure tests, the pipe samples must first be sealed at both ends and filled with water to release air in an environment of 20±5℃. Then, the pressure is increased to the target value at a constant rate using a pressure pump (for short-term tests, the pressure is recorded until the pipe bursts; for long-term tests, the specified ring stress is maintained for a preset time). During the test, pressure changes must be monitored in real time and the pressure drop during the pressure holding period must be ≤1%. Finally, the burst pressure, pressure holding results, or long-term stress extrapolation data are used to determine whether the pipe meets the nominal pressure requirements. After the test, the condition of the sample must be checked and complete data records must be kept. When testing the pipe, it is necessary to fix and seal the pipe.
[0004] In existing technologies, there is a problem that sealing pipes cannot accommodate pipes of different sizes. Therefore, when it is necessary to test PVC pipes of different sizes, different sealing components must be used. This makes the testing process cumbersome and significantly reduces efficiency.
[0005] Therefore, this utility model provides a pressure resistance test bench for PVC pipes. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A PVC pipe pressure resistance testing bench of this utility model includes a testing bench; an operating table is installed on one side of the testing bench; a first fixing plate is fixedly connected to the top of the testing bench; a first rubber plug is fixedly connected to one side of the first fixing plate; a support plate is provided at one end of the first rubber plug; the support plate is fixedly connected to the testing bench; a cylinder is fixedly connected to one side of the support plate; a second fixing plate is fixedly connected to one end of the cylinder; the second fixing plate is slidably connected to the testing bench; a second rubber plug is fixedly connected to one side of the second fixing plate; the second rubber plug is correspondingly arranged with the first rubber plug; multiple rubber rings are fixedly connected to the surfaces of the second and first rubber plugs; a through pipe connects the middle of the second fixing plate and the second rubber plug; during operation, one end of the pipe is first pressed against the first rubber plug, and the multiple rubber rings are placed concentrically. Different sized pipes are fitted into the gaps between rubber rings, which seal and secure the pipe ends. The control panel is then activated, activating a cylinder that pushes a second fixing plate closer to the other end of the pipe. The second rubber plug and rubber ring seal the pipe in the same way. A water pump is then connected to the pipe, allowing water to flow into it. A pressure pump is then connected to pressurize the pipe, and the pressure readings are observed and recorded when the pipe ruptures. Hot water can be introduced into the pipe using the same method to test its pressure resistance under high temperature and pressure. By using a first fixing plate, a first rubber plug, a second fixing plate, and a second rubber plug to seal and secure the pipe to be tested, and by incorporating a cylinder and rubber ring, the first rubber plug and second fixing plate can be used to seal and secure pipes of different sizes, reducing the need to change pipe sealing clamps and thus accelerating the testing of different pipes.
[0008] Preferably, the first fixing plate has a top plate on top, and multiple brackets are fixedly connected to the bottom of the top plate. The brackets are fixedly connected to the first fixing plate and the second fixing plate. Multiple heat lamps are provided on one side of the brackets, and the heat lamps are fixedly connected to the top plate. During operation, the test platform is operated to turn on the heat lamps, which irradiate the outside of the pipe. Injecting hot water into the pipe simulates the internal high-temperature environment, while the irradiation by the heat lamps simulates the external high-temperature environment of the pipe, thereby testing the high-temperature resistance of the pipe. By setting up the top plate, brackets, and heat lamps to simulate the high-temperature environment on the outside of the pipe, the quality of the pipe can be checked.
[0009] Preferably, the first fixing plate and the second fixing plate are provided with side plates on both sides. The side plates are hinged to the test table. During operation, the side plates can open outward and close inward under the control of the test table. In the event that the pipe will burst under high pressure or crack under high temperature, the side plates can block splashing water and pipe debris, thereby reducing the risk of splashing water and pipe debris to the test operators.
[0010] Preferably, a reflector is fixedly connected to one side of the side plate. The reflector is arranged in correspondence with the heating lamp. During operation, the reflector is aligned with the heating lamp and can reflect the light from the heating lamp to illuminate the bottom of the pipe, so that the pipe can be uniformly subjected to high temperature and reduce test errors.
[0011] Preferably, a water collection trough is provided on one side of the rubber ring. The water collection trough is located in the middle of the test platform. During operation, the water collection trough collects the water that is released after the pipe breaks, reducing the water from spreading everywhere and causing water waste, as well as reducing the damage to the operating platform or support plate caused by water.
[0012] Preferably, a waterproof cloth is provided on the outside of the cylinder. One end of the waterproof cloth is fixedly connected to the support plate, and the other end of the waterproof cloth is fixedly connected to the second fixing plate. During operation, the waterproof cloth protects the cylinder and reduces the impact of high temperature and humidity environment on the service life of the cylinder.
[0013] The beneficial effects of this utility model are as follows: 1. The PVC pipe pressure test bench of this utility model seals and fixes the pipe to be tested by setting a first fixing plate, a first rubber plug, a second fixing plate, and a second rubber plug. The cylinder and rubber ring enable the first rubber plug and the second fixing plate to be suitable for sealing and fixing pipes of different sizes, reducing the operation of changing pipe sealing clamps, thus improving the efficiency of testing different pipes.
[0014] 2. The PVC pipe pressure resistance test bench of this utility model simulates the high temperature environment on the outside of the pipe by setting up a top plate, a bracket and a heat lamp, so as to check the quality of the pipe. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1 to 3 As shown in the embodiment of this utility model, a PVC pipe pressure resistance test bench includes a test bench 1. An operating table 11 is installed on one side of the test bench 1. A first fixing plate 12 is fixedly connected to the top of the test bench 1. A first rubber plug 13 is fixedly connected to one side of the first fixing plate 12. A support plate 14 is provided at one end of the first rubber plug 13. The support plate 14 is fixedly connected to the test bench 1. A cylinder 15 is fixedly connected to one side of the support plate 14. A second fixing plate 16 is fixedly connected to one end of the cylinder 15. The second fixing plate 16 is slidably connected to the test bench 1. A second rubber plug 17 is fixedly connected to one side of the second fixing plate 16. The second rubber plug 17 is correspondingly arranged to the first rubber plug 13. Multiple rubber rings 18 are fixedly connected to the surfaces of the second rubber plug 17 and the first rubber plug 13. A through pipe 19 connects the middle of the second fixing plate 16 and the second rubber plug 17. During operation, one end of the pipe is first pressed against the first rubber plug 13, and the multiple rubber rings 18 are concentric. Different sized pipes are placed and secured in the gaps between rubber rings 18, which seal and fix the ends of the pipes. Then, the control panel 11 is operated to start the cylinder 15, which pushes the second fixing plate 16 closer to the other end of the pipe. The second rubber plug 17 and the rubber ring 18 seal the pipes in the same way. Then, the water pump is connected to the pipe 19 to introduce water into the pipe. Then, the pressure pump is connected to pressurize the pipe, and the pressure value is observed and recorded when the pipe ruptures. In the same way, hot water can be introduced into the pipe to test the pressure resistance of the pipe under high temperature and high pressure. By setting the first fixing plate 12, the first rubber plug 13, the second fixing plate 16, and the second rubber plug 17 to seal and fix the pipes to be tested, and by setting the cylinder 15 and the rubber ring 18, the first rubber plug 13 and the second fixing plate 16 can be used to seal and fix pipes of different sizes, reducing the operation of changing pipe sealing clamps, thus speeding up the testing efficiency of different pipes.
[0019] like Figures 1 to 4As shown, the first fixing plate 12 has a top plate 2 on top, and multiple brackets 21 are fixedly connected to the bottom of the top plate 2. The brackets 21 are fixedly connected to the first fixing plate 12 and the second fixing plate 16. Multiple heat lamps 22 are provided on one side of the brackets 21. The heat lamps 22 are fixedly connected to the top plate 2. When working, the test platform 1 is operated to turn on the heat lamps 22. The heat lamps 22 irradiate the outside of the pipe. The hot water injected into the pipe simulates the internal high temperature environment, while the irradiation by the heat lamps 22 simulates the external high temperature environment of the pipe, thereby testing the high temperature resistance of the pipe. By setting the top plate 2, brackets 21, and heat lamps 22 to simulate the high temperature environment on the outside of the pipe, the quality of the pipe can be checked.
[0020] like Figures 1 to 5 As shown, the first fixing plate 12 and the second fixing plate 16 are provided with side plates 3 on both sides. The side plates 3 are hinged to the test table 1. During operation, the side plates 3 can open outward and close inward under the control of the test table 1. In the event that the pipe will burst under high pressure or crack under high temperature, the side plates 3 can block the splashing water and pipe debris, reducing the risk of splashing water and pipe debris to the test operators.
[0021] like Figures 1 to 5 As shown, a reflector 4 is fixedly connected to one side of the side plate 3. The reflector 4 is set in correspondence with the baking lamp 22. When working, the reflector 4 corresponds to the baking lamp 22. The reflector 4 can reflect the light of the baking lamp 22 and irradiate the bottom of the pipe, so that the pipe can be evenly subjected to high temperature and reduce test error.
[0022] like Figures 1 to 3 As shown, a water collection tank 5 is provided on one side of the rubber ring 18. The water collection tank 5 is located in the middle of the test platform 1. During operation, the water collection tank 5 collects the water that is released after the pipe breaks, reducing the water from spreading everywhere and causing water waste, as well as reducing the damage to the operating platform 11 or the support plate 14 caused by water.
[0023] like Figures 1 to 3 As shown, a waterproof cloth 6 is provided on the outside of the cylinder 15. One end of the waterproof cloth 6 is fixedly connected to the support plate 14, and the other end of the waterproof cloth 6 is fixedly connected to the second fixing plate 16. During operation, the waterproof cloth 6 protects the cylinder 15 and reduces the impact of high temperature and humid environment on the service life of the cylinder 15.
[0024] Working principle: First, one end of the pipe is pressed against the first rubber plug 13. Multiple rubber rings 18 are placed concentrically, and pipes of different sizes are wedged into the gaps between the rubber rings 18. The rubber rings 18 seal and fix the end of the pipe. Then, the control panel 11 is operated to start the cylinder 15. The cylinder 15 pushes the second fixing plate 16 closer to the other end of the pipe. The second rubber plug 17 and the rubber rings 18 seal the pipe in the same way. Then, the water pump is connected to the connecting pipe 19 to introduce water into the pipe. Then, the pressure pump is connected to pressurize the pipe, and the pressure pump reading is observed. The pressure value data at the time of pipe rupture is recorded. Similarly, hot water can be introduced into the pipe to simultaneously test its pressure resistance under high temperature and pressure conditions. The pipe to be tested is sealed and fixed by setting a first fixing plate 12, a first rubber plug 13, a second fixing plate 16, and a second rubber plug 17. The cylinder 15 and rubber ring 18 allow the first rubber plug 13 and the second fixing plate 16 to be applicable to sealing and fixing pipes of different sizes, reducing the need to change pipe sealing clamps and thus accelerating the testing of different pipe materials. Efficiency is tested by manipulating test bench 1 and turning on the heat lamp 22. The heat lamp 22 irradiates the outside of the pipe. Hot water is injected into the pipe to simulate the internal high-temperature environment, while the irradiation by the heat lamp 22 simulates the external high-temperature environment of the pipe, thereby testing the pipe's high-temperature resistance. By setting up the top plate 2, bracket 21, and heat lamp 22 to simulate the high-temperature environment on the outside of the pipe, the quality of the pipe is checked. Under the control of test bench 1, the side plate 3 can open outward and close inward. Under high pressure, the pipe will burst; under high temperature, it will crack. Water splashed from the side plate 3 and... Pipe debris is blocked to reduce splashing water and the risk of pipe debris hazard to test operators. Reflector 4 corresponds to heat lamp 22 and can reflect the light from heat lamp 22 to illuminate the bottom of the pipe, so that the pipe can be evenly heated and reduce test errors. Water collection tank 5 collects water that spills out after the pipe breaks, reducing water spread and waste, and reducing water damage to operating table 11 or support plate 14. Waterproof cloth 6 protects cylinder 15 and reduces the impact of high temperature and humidity on the service life of cylinder 15.
