Description
Technical Field
[0001] This utility model relates to the field of air conditioner parts manufacturing technology, specifically a sealing test device for air conditioner copper pipes. Background Technology
[0002] Air conditioning copper pipes are key components in air conditioning (including household air conditioners, central air conditioners, refrigeration equipment, etc.) systems used to connect indoor and outdoor units and transmit refrigerant. They are usually made of high-purity seamless copper (T2 or TU1 standard) and are widely used due to their excellent thermal conductivity, ductility and machinability.
[0003] An investigation revealed a utility model patent (publication number: CN222166448U) disclosing a sealing test device for air conditioning copper pipe production. The device includes a test body, copper pipes, and a support frame. The bottom of the test body is fixedly connected to the top of the support frame. The copper pipes are located inside the test body. A ventilation detection component is fixedly connected to the left side of the test body, and a push detection component is fixedly connected to the bottom inside the test body. A control box is fixedly connected to the right side of the test body. This utility model, by setting up a control box to activate the ventilation detection component in conjunction with the push detection component, allows for simultaneous testing of multiple copper pipes. This solves the problem that existing test devices can only test one copper pipe at a time, which not only affects the production efficiency of copper pipes but also increases production costs and reduces the effectiveness of the test device. The utility model achieves the effect of simultaneously testing multiple copper pipes.
[0004] Although the aforementioned patent achieves the effect of simultaneous testing of multiple copper tubes through the above-mentioned structural arrangement, the sealing performance is not good during testing, and air leakage is prone to occur at the sealing point. Air leakage at the sealing point will cause the pressure of the testing system to drop, and even if the copper tube being tested itself has no leakage, it may be mistakenly judged as unqualified, resulting in errors in the test results. Due to the unstable sealing, repeated sealing operations and tests are required, which increases the time of a single test.
[0005] Therefore, this utility model provides a sealing test device for air conditioning copper pipes to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects 1. When sealing the air conditioner copper pipe port through the set sealing mechanism, the air bladder in the sealing mechanism is used to adapt and inflate the air conditioner copper pipe, which is consistent with the inner diameter of the air conditioner copper pipe. This helps to enhance the sealing performance of the air conditioner copper pipe port. After the air bladder is inflated, it expands evenly and can tightly fit the entire inner circumference surface of the air conditioner copper pipe, effectively avoiding local leakage caused by poor end face processing or deformation, thereby improving the accuracy of test results. 2. Through the set testing mechanism, the test can be carried out in a segmented moving test. The gas outlet pipe slowly contracts and moves inside the air conditioner copper pipe, releasing gas as it moves. This allows for segmented testing of the air conditioner copper pipe. When the gas outlet pipe moves in segments inside the copper pipe and releases gas, if a leak occurs in a certain segment, it can be accurately determined that the leak occurred in the pipe segment area corresponding to the current gas outlet segment.

[0017] 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.
[0018] This utility model provides a sealing test device for air conditioning copper pipes, such as... Figures 1-6 As shown, the sealing test device for air conditioning copper pipes includes a test box 1, a test mechanism is fixedly installed on one side of the test box 1, and a sealing mechanism is fixedly installed on the other side of the test box 1. The sealing mechanism includes an air pump 2, the outer surface of which is fixedly installed on the other side of the test chamber 1. The output end of the air pump 2 is fixedly connected to a transmission pipe 3, and one end of the transmission pipe 3 is fixedly connected to a connector 4. An air bladder 5 is fixedly connected to the outer surface of the connector 4. When sealing the port of the air conditioning copper pipe, the air bladder 5 in the sealing mechanism is used to inflate the air conditioning copper pipe to match the inner diameter of the air conditioning copper pipe, which helps to enhance the sealing performance of the air conditioning copper pipe port. After the air bladder 5 is inflated, it expands evenly and can tightly fit the entire inner circumference surface of the air conditioning copper pipe, effectively avoiding local leakage caused by poor end face processing or deformation, thereby improving the accuracy of the test results.
[0019] The testing mechanism includes an air pump 6, the outer surface of which is fixedly mounted on one side of the test chamber 1. The output end of the air pump 6 is fixedly connected to a connecting pipe 7, one end of which is fixedly connected to an air outlet pipe 8. The upper surface of the air outlet pipe 8 is fixedly connected to a wire 21, one end of which is fixedly connected to a controller 22. The outer surface of the air outlet pipe 8 is fixedly connected to an air outlet mechanism. During testing, the testing mechanism can be used to perform segmented moving tests. The air outlet pipe 8 slowly contracts and moves inside the air conditioning copper pipe, releasing air as it moves. This allows for segmented testing of the air conditioning copper pipe. When the air outlet pipe 8 moves segmentally inside the copper pipe and releases gas, if a leak occurs in a certain segment, it can be accurately determined that the leak occurred in the pipe segment area corresponding to the current air outlet segment.
[0020] The air outlet mechanism includes a sleeve 9, the inner wall of which is fixedly connected to the outer surface of the air outlet pipe 8. A telescopic tube 10 is fixedly connected to one end of the sleeve 9, and a telescopic head 11 is fixedly connected to one end of the telescopic tube 10. An A connecting ring 12 is fixedly connected to the outer surface of the sleeve 9. A sleeve 13 is fixedly connected to the side of the A connecting ring 12. A B connecting ring 14 is fixedly connected to one end of the sleeve 13. An A electromagnet 15 is sleeved on the inner wall of the sleeve 13. A spring 16 is fixedly connected to one end of the A electromagnet 15. One end of spring 16 is fixedly connected to electromagnet B 17. The end face of electromagnet B 17 is fixedly connected to the side of connecting ring B 14. Controller 22 is electrically connected to electromagnet A 15. When electromagnet A 15 and copper tube spring 16 drive electromagnet B 17 to move slowly by magnetic attraction, it can drive the air outlet pipe 8 to move in segments within the air conditioner copper pipe for testing. When the air outlet pipe 8 moves in segments within the copper pipe and releases gas, if a leak occurs in a certain segment, it can be accurately determined that the leak occurred in the pipe segment area corresponding to the current air outlet segment.
[0021] The top of both sides of the test chamber 1 is provided with a sliding groove, and a slider 18 is slidably connected inside the sliding groove. A protective plate 19 is fixedly connected to the side of the slider 18. During the air outlet test, in order to prevent the internal liquid from splashing out due to leakage of the air conditioning copper pipe, the protective plate 19 is used to protect and shield the pipe.
[0022] The surface of the test chamber 1 is provided with a water outlet hole, and a water outlet pipe 20 is fixedly installed inside the water outlet hole. A sealing plug is fitted inside the water outlet pipe 20. When it is necessary to release the liquid inside the test chamber 1, the liquid can be drained out using the water outlet pipe 20.
[0023] Specifically, soapy water is placed in test chamber 1, and the end of the air conditioner copper pipe is inserted into connector 4. According to the inner diameter of the air conditioner copper pipe, air pump 2 is started. Air pump 2 inflates air into air bag 5 through transmission pipe 3, so that air bag 5 wraps the inner wall of air conditioner copper pipe to enhance sealing. Then, air outlet pipe 8 is inserted into the other end of air conditioner copper pipe, and controller 22 is started. Controller 22 controls electromagnet A 15 through wire 21. Electromagnet A 15 slowly magnetically attracts electromagnet B 17 through spring 16. When magnetically attracted, electromagnet B 17 drives connecting ring B 14 and air outlet pipe 8 to move through telescopic pipe 10. While air outlet pipe 8 is moving, air pump 6 is started. Air pump 6 releases air into air outlet pipe 8 through connecting pipe 7, which can release air into air conditioner copper pipe to test whether there is leakage in air conditioner copper pipe. When releasing air, in order to prevent internal liquid from splashing out of air conditioner copper pipe due to leakage, protective plate 19 is used to protect and shield it.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
