The pipeline is composed of protective caps, transition joints, sealing gaskets, etc., and each disassembly and assembly takes time and effort.

[0004] There are certain safety risks in the process of blowing air through the pipeline.

DETAILED DESCRIPTION

[0026] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a pipeline continuity detection device, comprising: Bracket 100; The movable tube 102 is rotatably connected to the bracket 100, and a plurality of blowing tubes 104 for communicating with the pipeline to be tested are arranged on the movable tube 102; The exhaust pipe 106 is used to communicate with the pipeline to be tested. The exhaust pipe 106 is arranged in a one-to-one correspondence with the blowing pipe 104. The exhaust pipe 106 is provided with an air volume detection member 108.

[0028] According to the pipeline on-off detection device provided by the embodiment of the first aspect of the present invention, multiple blowing pipes 104 arranged on the movable pipe 102 can simultaneously blow air into multiple pipelines to be tested, and detect it through the air volume detection member 108 on the corresponding exhaust pipe 106. This design greatly improves the detection efficiency, especially when a large number of pipelines need to be tested on-off. Since the air volume detection member 108 is used to detect the air volume passing through the exhaust pipe 106, the on-off state of the tested pipeline can be accurately judged. If the pipeline is unobstructed, the air volume will meet the preset standard; if the pipeline is blocked or there are other problems, the air volume will change, so that the problem can be discovered and located in time. The movable pipe 102 is rotatably connected to the bracket 100, so that the blowing pipe 104 can be easily connected to the tested pipeline. At the same time, the setting of the clamping groove 110 also simplifies the clamping process of the tested pipeline and improves the simplicity of operation. The device is suitable for pipeline detection of various sizes, and it only needs to select a suitable blowing pipe 104 and a clamping groove 110 according to the size of the tested pipeline. In addition, the device can also be used to detect pipelines made of different materials, such as metal pipes, plastic pipes, etc.

[0029] Please continue to see Figures 1 to 4 The first embodiment of the present invention provides a pipeline continuity detection device, which mainly includes the following components: The bracket 100 serves as the basic supporting structure of the entire detection device and is used to fix and support other components.

[0030] The movable tube 102 is rotatably connected to the bracket 100, which means that the movable tube 102 can rotate or swing relative to the bracket 100. The movable tube 102 is provided with a plurality of blowing tubes 104, which are used to communicate with the pipeline to be tested so as to blow air into the pipeline to be tested.

[0031] The exhaust pipe 106 is also connected to the pipeline to be tested, and is arranged one-to-one with the blowing pipe 104. An air volume detection member 108 is arranged on the exhaust pipe 106, and the air volume detection member 108 is used to detect the air volume passing through the exhaust pipe 106.

[0032] The pipeline continuity detection device provided in the embodiment of the first aspect of the present invention has the advantages of high efficiency, accuracy, simple operation and wide application range, and can effectively solve the problems existing in the prior art and improve the efficiency and accuracy of pipeline continuity detection.

[0033] According to an embodiment of the present invention, it also includes a clamping groove 110 arranged in a one-to-one correspondence with the blowing pipe 104, and the clamping groove 110 is arranged on the bracket 100, and the clamping groove is used to clamp the measured pipeline.

[0034] In a specific embodiment of the present invention, in addition to the basic components and detection method of the pipeline continuity detection device mentioned above, clamping grooves 110 are further provided that correspond to the blowing pipes 104. These clamping grooves 110 are designed and fixed on the bracket 100, and their main function is to clamp the pipeline to be tested, ensuring that the pipeline to be tested can be stably and firmly connected to the blowing pipe 104 and the exhaust pipe 106 during the detection process.

[0035] More importantly, by setting the clamping groove 110, not only can the tested pipeline be clamped, but also the tested pipeline can be simply and directly judged whether the curvature of the tested pipeline meets the requirements by comparing the tested pipeline with the clamping groove 110. Taking the copper tube of the differential pressure valve as an example, the copper tube of the differential pressure valve itself has certain curvature requirements, so the clamping groove 110 can be set to the same form as the bending angle of the copper tube of the differential pressure valve. For example, the clamping groove 110 can be made of nylon material with a plane angle of 349.5° and a vertical angle of 20°, which plays the role of error prevention and detection of the copper tube of the differential pressure valve.

[0036] That is, the design of the clamping groove 110 takes into account the diversity of the tested pipelines, including different sizes, shapes and materials. Therefore, the shape, size and material of the clamping groove 110 are carefully selected to meet the needs of various tested pipelines. At the same time, the clamping groove 110 can also have a certain degree of elasticity and adjustability to better adapt to pipelines of different sizes and ensure that they are firmly clamped.

[0037] The use of the clamping groove 110 ensures the stability of the tested pipeline during the detection process and avoids detection errors caused by shaking or moving the pipeline. This greatly improves the accuracy of the detection and makes the detection results more reliable. The tested pipeline is quickly and conveniently clamped by the clamping groove 110, which greatly shortens the preparation time before the detection. At the same time, since the pipeline is stably clamped, the operation during the detection process becomes smoother, thereby improving the overall detection efficiency. The design of the clamping groove 110 takes into account the protection of the tested pipeline. By using soft and wear-resistant materials to make the clamping groove 110, damage to the pipeline caused by over-tight clamping is avoided. This helps to extend the service life of the tested pipeline and reduce detection failures caused by pipeline damage. Since the clamping groove 110 is adjustable and adaptable, the detection device can be applied to pipelines of various sizes and shapes. This makes the device have broad application prospects in multiple fields and scenarios.

[0038] According to one embodiment of the present invention, each blowing pipe 104 is provided with a one-way valve.

[0039] In a specific embodiment of the present invention, in order to further optimize the performance of the pipeline continuity detection device, a one-way valve is provided on each blowing pipe 104. The main function of the one-way valve is to control the one-way flow of airflow, that is, to only allow air to blow from the blowing pipe 104 into the pipeline to be tested, and to prevent air from flowing back from the pipeline to be tested to the blowing pipe 104. This design can prevent inaccurate test results or equipment damage caused by airflow backflow during the test process.

[0040] The setting of the one-way valve can prevent the airflow from flowing back, thus avoiding inaccurate test results or equipment damage caused by backflow. This helps to improve the accuracy and reliability of the test.

[0041] According to one embodiment of the present invention, the blowing pipe 104 is rotatably connected to the movable pipe 102 .

[0042] In the embodiment of the present invention, the blowing pipe 104 can rotate or swing relative to the movable pipe 102 within a certain range. This design increases the flexibility of the blowing pipe 104, making it easier to align and connect the blowing pipe 104 with the pipeline to be tested, especially when the position or direction of the pipeline to be tested is complex. At the same time, this design also helps to adjust the angle of the blowing pipe 104 as needed during the detection process to obtain more accurate detection results.

[0043] The design that the blowing pipe 104 is rotatably connected to the movable pipe 102 increases the flexibility of the device, making it easier to align and connect the blowing pipe 104 with the pipeline to be tested, which helps to simplify the testing process and improve the testing efficiency.

[0044] According to one embodiment of the present invention, the outlet of the blowing pipe 104 and / or the inlet of the exhaust pipe 106 is provided with a quick-connect connector 112 for communicating with the pipeline to be tested.

[0045] like Figure 1 and Figure 2 As shown, a quick connector 112 for connecting with the tested pipeline is provided at the outlet of the blowing pipe 104 and / or the inlet of the exhaust pipe 106. The design of the quick connector 112 is intended to simplify the pipeline connection process, improve the connection efficiency, and ensure the stability and sealing of the connection.

[0046] The quick connector 112 generally has the characteristics of easy operation, quick connection, and reliable sealing. In an embodiment of the present invention, the quick connector 112 is applied to the blow pipe 104 and the exhaust pipe 106, making the connection with the measured pipeline more convenient. Specifically, the quick connector 112 may include components such as a connector body, a sealing element, and a locking mechanism. The connector body is used to connect to the measured pipeline or the blow pipe 104 / exhaust pipe 106, and the sealing element is used to ensure the sealing of the connection to prevent gas leakage. The locking mechanism is used to firmly lock the connector body and the measured pipeline or the blow pipe 104 / exhaust pipe 106 together to ensure the stability of the connection.

[0047] The design of the quick connector 112 makes it faster and more convenient to connect the blow pipe 104 and the exhaust pipe 106 to the pipeline to be tested. Compared with the traditional connection method, the quick connector 112 can greatly shorten the connection time and improve the detection efficiency. The quick connector 112 firmly locks the connector body with the pipeline to be tested or the blow pipe 104 / exhaust pipe 106 through a locking mechanism to ensure the stability of the connection. This helps to prevent inaccurate test results or equipment damage caused by loose connections during the detection process. The sealing element in the quick connector 112 is used to ensure the sealing of the connection and prevent gas leakage. This is crucial to ensure the accuracy of the test results and the normal operation of the equipment. The design of the quick connector 112 has certain versatility and adaptability, and can be applied to pipeline connections of different sizes and shapes. This makes the present invention have broad application prospects in multiple fields and scenarios.

[0048] According to one embodiment of the present invention, the quick-connect connector 112 includes: A housing 114, wherein an installation space is provided in the housing 114, an opening communicating with the installation space is provided at one end of the housing 114, and a fixed clamping portion 116 and a movable clamping portion 118 are provided on an inner wall of the opening; The first elastic member 120 is disposed in the installation space, and two ends of the first elastic member 120 abut against the inner wall of the installation space and between the fixing clamping portion 116 .

[0049] like Figure 3 and Figure 4 As shown, the housing 114 is the main body of the quick connector 112, and an installation space is provided inside the housing 114 for accommodating and supporting other components. An opening communicating with the installation space is provided at one end of the housing 114, and the opening is used to connect with the pipeline to be tested.

[0050] The inner wall of the opening is designed with a special structure, including a fixed clamping portion 116 and a movable clamping portion 118. These two parts work together to ensure that the measured pipeline can be firmly connected to the quick-connect connector 112.

[0051] The housing 114 is usually made of high-strength, corrosion-resistant material to ensure that it can withstand certain pressure and wear during use while maintaining good sealing performance.

[0052] The first elastic member 120 is disposed in the installation space of the housing 114, and its two ends are respectively abutted between the inner wall of the installation space and the fixed clamping portion 116. The main function of the first elastic member 120 (such as a spring) is to provide elastic force so that the movable clamping portion 118 can maintain a certain tension state, so that the tested pipeline can be tightly clamped when the tested pipeline is inserted into the opening to prevent it from falling off.

[0053] The first elastic member 120 can also assist in sealing to a certain extent, ensuring that the gas at the connection does not leak.

[0054] Through the cooperation of the fixed clamping part 116 and the movable clamping part 118, as well as the elastic force provided by the first elastic member 120, the quick connector 112 can ensure that the connection with the tested pipeline or other tested pipelines is stable and reliable, and is not easy to fall off. The design of the quick connector 112 makes the connection and disconnection operations very simple and quick. The user only needs to insert the tested pipeline into the opening and gently rotate or push to complete the connection, which greatly improves work efficiency. The quick connector 112 adopts a special sealing structure, such as sealing elements such as O-rings, combined with the auxiliary sealing effect of the first elastic member 120, which can ensure that the gas at the connection will not leak, thereby ensuring the accuracy of the test results. The design of the quick connector 112 has certain versatility and adaptability, and can be applied to the connection requirements of pipelines of different sizes and shapes, providing users with more choices.

[0055] According to an embodiment of the present invention, a sealing member 122 is further disposed in the housing 114 at a position corresponding to the opening.

[0056] like Figure 3 As shown, a seal 122 is added to the position corresponding to the opening in the housing 114. This design is intended to further enhance the sealing performance of the quick-connect connector 112, ensuring that when the measured pipeline is connected, gas will not leak from the connection, thereby maintaining the integrity and accuracy of the detection system.

[0057] The seal 122 is usually an annular or gasket-shaped structure made of elastic material (such as rubber, silicone or polyurethane, etc.), and its size and shape match the opening. When the measured pipeline is inserted into the opening and matched with the fixed clamping part 116 and the movable clamping part 118, the seal 122 will be compressed and fit tightly between the outer wall of the pipeline and the inner wall of the opening, forming an effective sealing barrier.

[0058] The addition of the seal 122 significantly improves the sealing performance of the quick connector 112. It can effectively prevent gas leakage from the connection and ensure the integrity and accuracy of the detection system. This is crucial for pipeline continuity detection devices that require high-precision measurements. In addition to providing a sealing function, the seal 122 can also enhance the stability of the connection to a certain extent. When the measured pipeline is subjected to external force, the elasticity of the seal 122 can absorb part of the impact force and prevent the connection from loosening or falling off. The seal 122 is usually made of wear-resistant and corrosion-resistant materials, so it has good durability. It can maintain sealing performance for a long time and reduce equipment failures and maintenance costs caused by leakage. The design of the seal 122 makes the connection operation of the quick connector 112 smoother and more reliable. Users do not need to worry about leakage or loosening at the connection, thereby improving the user experience and satisfaction.

[0059] According to an embodiment of the present invention, a second elastic member 124 is disposed between the movable clamping portion 118 and the housing 114 . A locking member 126 is also disposed on the housing 114 . The locking member 126 is disposed at one end of the second elastic member 124 away from the movable clamping portion 118 .

[0060] like Figure 3 As shown, a second elastic member 124 is additionally provided between the movable clamping portion 118 and the housing 114 , and a locking member 126 is provided on the housing 114 . The locking member 126 is located at one end of the second elastic member 124 away from the movable clamping portion 118 .

[0061] The second elastic member 124 (such as a spring or an elastic sheet) is designed between the movable clamping portion 118 and the housing 114. Its main function is to provide a continuous elastic force so that the movable clamping portion 118 can maintain a certain tension state. When the measured pipeline is inserted into the opening of the quick-connect connector 112, the movable clamping portion 118 will be squeezed by the pipeline and move inward, while compressing the second elastic member 124. Once the pipeline is fully inserted, the elastic force of the second elastic member 124 will cause the movable clamping portion 118 to rebound quickly and tightly clamp the pipeline, thereby ensuring the stability of the connection.

[0062] In addition, a locking member 126 is provided on the housing 114. The locking member 126 is designed to further fix the movable clamping portion 118 to prevent it from loosening or falling off in unexpected circumstances (such as when the pipeline is subjected to a large external force). The locking member 126 can be operated by rotating, sliding or pressing to achieve locking and unlocking of the movable clamping portion 118.

[0063] The addition of the second elastic member 124 enables the active clamping portion 118 to clamp the measured pipeline more tightly, thereby significantly enhancing the stability of the connection. Even if the pipeline is subjected to a large external force, the reliability of the connection can be maintained. The setting of the locking member 126 further improves the safety of the quick connector 112. By locking the active clamping portion 118, it can be prevented from loosening or falling off in an unexpected situation, thereby avoiding possible leakage or equipment damage. Although the second elastic member 124 and the locking member 126 are added, our design still maintains the convenience of the quick connector 112. The user only needs to simply insert the pipeline into the opening and gently rotate or press the locking member 126 to complete the connection and locking operation. This design enables the quick connector 112 to be suitable for pipeline connection requirements of different sizes and shapes. By adjusting the position and shape of the active clamping portion 118 and the locking member 126, it can easily adapt to various pipeline connection scenarios.

[0064] like Figure 5 As shown, the second aspect of the present invention provides a detection method of the pipeline continuity detection device as described above, comprising: Step 10, connecting the two ends of the pipeline to be tested to the blowing pipe 104 and the exhaust pipe 106 respectively; Step 20, judging the continuity of the tested pipeline by means of the air volume detection component.

[0065] According to the pipeline on-off detection method provided by the embodiment of the second aspect of the present invention, the on-off state of the pipeline is determined by directly measuring the air volume passing through the pipeline under test, and it has the characteristics of being fast and accurate. Compared with the traditional detection method, this method can find problems more quickly and improve the detection efficiency. The operation steps of the method are simple and clear. It only needs to connect the pipeline under test to the detection device and start the detection device. This reduces the difficulty of operation and makes it easy for non-professionals to get started. The method is suitable for pipeline detection of various sizes and materials. It only needs to select appropriate detection devices and parameters according to the actual situation of the pipeline under test. This improves the flexibility and applicability of the method. The air volume passing through the pipeline under test is detected by the air volume detection member 108, which can accurately reflect the on-off state of the pipeline. This method is more reliable than traditional visual inspection or hand-feel inspection, and can more effectively find potential problems.

[0066] Please continue to see Figure 5The second aspect of the present invention provides a detection method for the above pipeline continuity detection device, which mainly includes the following steps: Connect the pipeline to be tested: First, the two ends of the pipeline to be tested are connected to the blowing pipe 104 and the exhaust pipe 106 on the detection device respectively. This step is the basis of the detection process, ensuring that an effective air flow channel is formed between the pipeline to be tested and the detection device.

[0067] Determine the continuity of the tested pipeline through the air volume detection component: After the connection is completed, the detection device is started to blow air into the pipeline to be tested through the blowing pipe 104. Then, the air volume detection member 108 on the exhaust pipe 106 detects the air volume passing through the exhaust pipe 106. According to the change of the air volume, the on-off state of the pipeline to be tested can be determined.

[0068] If the air volume meets the preset standard value or is within the preset normal range, it can be considered that the tested pipeline is unobstructed.

[0069] If the air volume is significantly lower than the preset standard value or exceeds the normal range, it may indicate that there is a blockage, leakage or other problems in the tested pipeline, which requires further inspection and confirmation.

[0070] According to one embodiment of the present invention, the pipeline continuity detection device further includes a clamping groove 110 arranged in one-to-one correspondence with the blowing pipe 104, and the detection method further includes: The pipeline to be tested is placed in the clamping groove 110 to determine the bending angle of the pipeline to be tested.

[0071] In the embodiment of the present invention, the pipeline continuity detection device is further improved, specifically in that a clamping groove 110 is added that is arranged in a one-to-one correspondence with the blowing pipe 104. This design not only provides a stable support platform for the pipeline under test, but also enables the tester to easily determine the bending angle of the pipeline under test, thereby more comprehensively evaluating the performance and status of the pipeline.

[0072] The clamping groove 110 is usually designed to match the shape and size of the outlet of the blowing pipe 104 to ensure that the pipeline to be tested can be firmly placed therein. The material of the clamping groove 110 is usually selected to be high-strength and corrosion-resistant to withstand the pressure and wear that may be generated during the detection process. In addition, the surface of the clamping groove 110 can also be anti-slip treated to increase the friction between the pipeline to be tested and prevent it from sliding or falling off during the detection process.

[0073] In terms of the detection method, this embodiment also introduces a new step: placing the pipeline to be tested in the clamping groove 110 to determine the bending angle of the pipeline to be tested.

[0074] This step is usually performed before connecting the tested pipeline to the blowpipe 104. The inspector can visually judge whether the bending angle of the tested pipeline meets the requirements by observing the placement of the tested pipeline in the clamping groove 110. If the bending angle is too large or too small, it may affect the on-off performance and service life of the pipeline, so it needs to be adjusted or replaced in time.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
