Description

Technical Field

[0001] This utility model relates to the field of condenser leak detection technology, and in particular to a condenser leak detection device. Background Technology

[0002] A condenser leak detection device is used to monitor and identify internal leaks in a condenser system. It is widely used in the steam turbine condensing systems of thermal power plants and nuclear power plants. By monitoring the gas composition, pressure changes, or other relevant parameters in the cooling water system or vacuum system in real time, the device can issue an early warning when a minor leak occurs in the condenser, ensuring safe operation of the equipment, improving operating efficiency, and providing important information for subsequent maintenance and repair.

[0003] An investigation revealed that a Chinese utility model patent discloses a condenser heat exchanger tube leak detection device (publication number: CN221123744U). Although the aforementioned patent can effectively detect leaks in the heat exchanger tube body through the setting of the leak detection components, and the leak detection efficiency of the heat exchanger tube body is relatively high, if the rubber plug tube is pulled out directly after the leak detection is completed, the high-pressure gas will be discharged directly and rapidly, which may result in excessive airflow speed and excessive impact force. This may not only easily generate noise and equipment vibration, but also pose a safety hazard to the operator. Utility Model Content

[0004] Given that the existing method of directly pulling out the rubber plug after leak detection results in the direct and rapid discharge of high-pressure gas, which may lead to excessively fast airflow and excessive impact force, it is not only easy to generate noise and equipment vibration, but may also pose a safety hazard to operators. Therefore, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a condenser leak detection device. Its purpose is that: after the leak detection is completed, the rubber plug tube is pulled out directly, and the high-pressure gas will be discharged directly and quickly, which may result in excessive airflow speed and excessive impact force. This may not only easily generate noise and equipment vibration, but also pose a safety hazard to the operator.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a condenser leak detection device, including a condenser assembly, a leak detection structure, and a venting structure. The leak detection structure is installed on the condenser assembly, and the venting structure is installed on the leak detection structure. The venting structure includes a rotating seat, a rotating shaft, a second sealing plate, a motor, a fixing ring, and a spring. The rotating seat is equipped with the second sealing plate through the motor and the rotating shaft. The fixing ring is fixedly installed on the outer wall of the connecting cylinder. One end of the spring is fixedly connected to the fixing ring, and a venting cap is fixedly installed on the free end of the spring at the top of the outlet pipe.

[0007] As a preferred embodiment of the condenser leak detection device of this utility model, the condenser assembly includes a shell, pipes and connecting plates, the pipes are disposed inside the shell, and the connecting plates are fixedly installed on the outer walls at both ends of the shell.

[0008] As a preferred embodiment of the condenser leak detection device of this utility model, the leak detection structure includes a first sealing plate, a base frame and an air pump. A sealing plug adapted to the pipeline is fixedly installed on the first sealing plate, and the base frame is fixedly installed on the top of the outer side of the outer shell.

[0009] In a preferred embodiment of the condenser leak detection device of this utility model, the air pump is fixedly installed at the top of the base frame, the air pump inlet end is connected to an air inlet pipe, the air pump outlet end is connected to an air outlet pipe, and a support frame is fixedly installed at the top of the base frame to support the air outlet pipe.

[0010] As a preferred embodiment of the condenser leak detection device of this utility model, a connecting cylinder is fixedly installed at the end of the outlet pipe away from the air pump, a connecting pipe is fixedly connected to the connecting cylinder, a rubber plug is fixedly connected to the end of the connecting pipe away from the connecting cylinder, the rubber plug, the connecting pipe, the connecting cylinder and the outlet pipe are internally interconnected, and a pressure gauge is installed on the outlet pipe.

[0011] In a preferred embodiment of the condenser leak detection device of this utility model, the rotating seat is fixedly installed on both sides of the connecting cylinder, the rotating shaft is rotatably installed between the rotating seats, the second sealing plate is fixedly installed on the rotating shaft, the motor is fixedly installed on the outside of the rotating seat, and the motor shaft of the motor is fixedly connected to one end of the rotating shaft.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the set venting structure, the motor drives the rotating shaft to rotate the second sealing plate, realizing the controllable release of high-pressure gas in the connecting cylinder. At the same time, by utilizing the elastic cooperation between the vent cap and the spring, the spring reaction force buffers the pressure relief impact when the gas flows out, reducing the high-pressure gas injection rate and avoiding the impact of instantaneous high-pressure airflow on personnel, thus ensuring the safety of the pressure relief process. Furthermore, the automated control improves the ease of operation, achieving a dual optimization of pressure relief efficiency and safety protection.

[0014] 2. Through the designed leak detection structure, the first sealing plate and the sealing plug work together to seal one end of the pipeline, and the rubber plug self-seals the other end, forming an independent air pressure detection space. By using an air pump to fill the gas and a pressure gauge to monitor the air pressure changes in real time, the leak point of a single pipeline can be accurately located. The detection efficiency is high and the operation is convenient. At the same time, the segmented isolation detection avoids the interference of gas leakage in multiple pipelines in traditional methods, and can quickly determine the pipeline sealing performance, effectively improving the accuracy and economy of condenser leak detection.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Refer to attached figure Figure 1 - Appendix Figure 4The first embodiment of this utility model provides a condenser leak detection device, including a condenser assembly 1, a leak detection structure 2 and a venting structure 3. The leak detection structure 2 is installed on the condenser assembly 1, and the venting structure 3 is installed on the leak detection structure 2. The condenser assembly 1 includes a shell 11, a pipe 12 and a connecting plate 13. The pipe 12 is disposed inside the shell 11, and the connecting plate 13 is fixedly installed on the outer walls of both ends of the shell 11.

[0027] The leak detection structure 2 includes a first sealing plate 21, a base frame 23, and an air pump 24. A sealing plug 22, compatible with the pipe 12, is fixedly installed on the first sealing plate 21. When the first sealing plate 21 is fixedly connected to the pipe 12 by bolts, the sealing plug 22 is inserted into the pipe 12 to seal one end of the pipe 12. The base frame 23 is fixedly installed on the top of the outer side of the outer casing 11. The air pump 24 is fixedly installed on the top of the base frame 23. The air pump 24 has an air inlet pipe connected to its air inlet end. 4. An air outlet pipe 25 is connected to the air outlet end. A support frame is fixedly installed at the top of the base frame 23 to support the air outlet pipe 25. A connecting cylinder 26 is fixedly installed at the end of the air outlet pipe 25 away from the air pump 24. A connecting pipe 27 is fixedly connected to the connecting cylinder 26. A rubber plug tube 28 is fixedly connected to the end of the connecting pipe 27 away from the connecting cylinder 26. The rubber plug tube 28, the connecting pipe 27, the connecting cylinder 26 and the air outlet pipe 25 are internally interconnected. A pressure gauge 29 is installed on the air outlet pipe 25.

[0028] During use, when the first sealing plate 21 is fixedly connected to the pipe 12 with bolts, the sealing plug 22 is inserted into the pipe 12 to seal one end of the pipe 12. Then, the rubber plug tube 28 is inserted into the other end of the pipe 12 to seal the pipe 12. The rubber plug tube 28 automatically seals the pipe 12. The air pump 24 is started, and external air enters from the air inlet pipe and then flows out through the air outlet pipe 25. The gas enters the rubber plug tube 28 through the connecting cylinder 26 and the connecting pipe 27, and finally flows into the pipe 12. The air pressure in the pipe 12 increases. When the air pressure increases to the required pressure, the air pump 24 is turned off and a period of time is waited. The air pressure inside the pipe 12 is constantly observed by setting the air pressure gauge 29. When the air pressure does not change, it means that the pipe 12 is not leaking. When the air pressure gauge 29 shows that the air pressure drops, it means that the pipe 12 is leaking. Thus, the pipe 12 is leak-tested. Then, the above operation is repeated to test other pipes 12 in turn.

[0029] Example 2

[0030] Refer to attached figure Figure 5 and attached Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0031] The venting structure 3 includes a rotating seat 31, a rotating shaft 32, a second sealing plate 33, a motor 34, a fixing ring 36, and a spring 37. The rotating seat 31 is fixedly installed on both sides of the connecting cylinder 26. The rotating shaft 32 is rotatably installed between the rotating seats 31. The second sealing plate 33 is fixedly installed on the rotating shaft 32. A sealing ring is provided on the outer ring of the second sealing plate 33 to improve the sealing performance. The cavity of the connecting cylinder 26 is divided into two parts by the second sealing plate 33. The motor 34 is fixedly installed on the outside of the rotating seat 31, and the motor shaft of the motor 34 is fixedly connected to one end of the rotating shaft 32. The fixing ring 36 is fixedly installed on the outer wall of the connecting cylinder 26. One end of the spring 37 is fixedly connected to the fixing ring 36. A vent cap 35 is fixedly installed on the free end of the spring 37. The vent cap 35 is at the top of the vent pipe 25.

[0032] During use, after the leak detection of pipeline 12 is completed, the motor 34 is started. The motor shaft of the motor 34 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the second sealing plate 33 to rotate, so that the two cavities inside the connecting cylinder 26 are connected, allowing the high-pressure gas inside the connecting cylinder 26 to flow out from the top of the connecting cylinder 26. The gas flows out from the gap between the vent cap 35 and the connecting cylinder 26. At the same time, when the gas flows out, it comes into contact with the vent cap 35, pushing the vent cap 35 upward and stretching the spring 37. Through the reaction force of the spring 37, the vent cap 35 is buffered. By setting the vent cap 35, the rate of high-pressure gas outflow is reduced, ensuring the safety of personnel.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
