Description

Technical Field

[0001] The present invention relates to the technical field of non - metallic expansion joints, and more specifically to a non - metallic expansion joint with anti - corrosion and zero leakage. Background Art

[0002] A non - metallic expansion joint is an important component used to compensate for deformation and displacement in a pipeline system. Among them, the common non - metallic expansion joint mainly consists of installation components, an expansion body, and flanges, etc. The specific working process of the non - metallic expansion joint is as follows: The non - metallic expansion joint is installed in the pipeline system through the installation components. When the pipeline system undergoes temperature changes, pressure changes, etc., the expansion body will undergo corresponding deformation and displacement, thereby absorbing the stress and deformation in the pipeline system. By absorbing the deformation and displacement, the non - metallic expansion joint can reduce the stress and deformation of the pipeline system and ensure the normal operation of the pipeline system. Among them, the non - metallic expansion joint not only has functions such as compression resistance, sealing, impact resistance, shock absorption, and noise reduction, but also can reduce pipeline deformation and improve the service life of the pipeline. During the installation process of the expansion body, grooves will be formed inside it. During the operation process, the acid - base liquid after spraying and atomization in the pipeline accumulates in the grooves, causing corrosion to the inside of the expansion body. Over time, the corrosion area becomes larger. If the replacement is not timely, leakage will occur, and then the non - metallic expansion joint cannot work properly. When the non - metallic expansion joint leaks, it can mainly be discovered through manual maintenance. Therefore, when manual inspection cannot detect the leakage of the expansion joint in real - time, it may lead to the non - metallic expansion joint being unable to work properly, resulting in certain economic losses. At the same time, during the use of the non - metallic expansion joint, vibration occurs at the connection end between the pipeline system and the flange, so that the installation components are not completely limited, and then leakage occurs at the connection between the flange and the pipeline system, resulting in certain economic losses.

[0032] In the embodiment of the present application, the specific working process of this part of the application embodiment is as follows: when the extrusion column 411 contacts the weight sensor 412, pressure data is generated and transmitted to the data acquisition end. The data acquisition end transmits the pressure data to the analysis unit. The analysis unit judges whether there is an incomplete limit situation at the connection between the flange 101 and the pipeline system through the change of the real-time pressure data. When the analysis unit judges that there is a complete connection situation between the flange 101 and the pipeline system, the control unit drives the electric control lifting column 407 to input current, controls the flange 101 to move towards the pipeline system direction, increases the extrusion force exerted by the flange 101 on the pipeline system, and drives the two to be in a fitting state, which is beneficial to achieving the function of temporarily limiting and fixing the flange 101 and the pipeline system, and avoiding liquid leakage during the use of the non-metallic expansion joint 1.

[0033] Refer to Figure 3 And Figures 6 to 9 As shown in the figure, the present invention provides a non-metallic expansion joint that can prevent corrosion and has zero leakage. The leak prevention device 5 includes an annular frame 501. On the inner wall of the annular frame 501, a telescopic column 504 is installed. The compressed air and adsorbed air generated by the air delivery mechanism 3 are delivered into the telescopic column 504, driving the telescopic column 504 to perform stretching and contracting operations. One end of the telescopic column 504 is installed with a second hollow ring 505. On the side of the second hollow ring 505, a first rubber connector 506 is installed. At the middle position of the inner wall of the second hollow ring 505, a second connecting plate 507 is installed. On the side of the second connecting plate 507, a third rubber connector is installed. At both ends of the second connecting plate 507, third springs 508 are installed. At the position far from the second connecting plate 507, an annular stretching plate 502 and a second rubber connector 510 are installed on the third springs 508.

A rubber ring frame 503 is installed on the inner wall of the annular stretching plate 502, and a sealing rubber ring 509 is installed on the outer wall of the rubber ring frame 503.

[0034] The rubber ring frame 503 is provided with an adsorption groove at a position close to the expansion body 103. When the rubber ring frame 503 is extruded onto the surface of the expansion body 103, the rubber ring frame 503 deforms, driving the air inside the adsorption groove to be discharged, thereby driving the rubber ring frame 503 to adsorb on the outer wall of the expansion body 103; A long spring is installed on the inner wall of the telescopic column 504, which is beneficial to driving the telescopic column 504 to return to its original state.

[0035] In the embodiment of the present application, by providing the first rubber connecting body 506, the second rubber connecting body 510 and the third rubber connecting body, it is beneficial for the annular stretching plate 502 and the second hollow ring 505 to be in an integral connection state during the moving process.

[0036] In the embodiment of the present application, the specific working process of this part of the application embodiment is as follows: during the working process of the non-metallic expansion joint 1, the compressed air generated by the air conveying mechanism 3 is conveyed into the telescopic column 504, driving the telescopic column 504 to be in a stretched state. The stretched telescopic column 504 drives the second hollow ring 505, the annular stretching plate 502 and the rubber ring frame 503 to move towards the expansion body 103. The rubber ring frame 503 is extruded onto the surface of the expansion body 103, and the rubber ring frame 503 deforms, driving the air inside the adsorption groove to be discharged, thereby driving the rubber ring frame 503 to adsorb on the outer wall of the expansion body 103. At the same time, the air conveying mechanism 3 drives the telescopic column 504 to perform stretching and contracting operations by changing the content of compressed air inside the telescopic column 504 and under the spring force of the long spring, thereby driving the expansion body 103 to vibrate, so as to facilitate the acidic solution attached to the inner wall of the expansion body 103 to fall off, avoid the acidic solution from corroding the inner wall of the expansion body 103, increase the service life of the expansion body 103. When the analysis unit determines that the expansion body 103 has a leakage situation, the air conveying mechanism 3 conveys compressed air to the telescopic column 504, driving each group of rubber ring frames 503 and sealing rubber rings 509 to adhere to the surface of the expansion body 103, covering the leakage part on the surface of the expansion body 103, achieving the effect of temporarily plugging the leakage part of the expansion body 103.

[0037] Referring to Figures 1 to 9 As shown in the figure, the present invention provides a non-metallic expansion joint that can prevent corrosion and has zero leakage. The data acquisition end receives the real-time pressure data monitored by the weight sensor 412 and the real-time humidity data detected by the humidity sensor 404, and conveys them to the analysis unit; When the analysis unit simulates the normal connection state of the flange 101 and the pipeline system, it generates simulated pressure data of the weight sensor 412 and integrates the simulated pressure data to form a first threshold range. When the analysis unit simulates the normal working state of the expansion body 103, it generates simulated humidity data of the humidity sensor 404 and integrates the simulated humidity data to form a second threshold range; The analysis unit compares the real-time pressure data with the first threshold range. When the real-time pressure data is not within the first threshold range, it can be determined that the connection between the flange 101 and the pipeline system is incomplete. The analysis unit sends a first execution instruction to the control unit. The analysis unit compares the real-time humidity data with the second threshold range. When the real-time humidity data is greater than the second threshold range, it can be determined that there is a leakage in the expansion body 103. The analysis unit sends a second execution instruction to the control unit; After receiving the first execution instruction, the control unit controls the input current of the expansion mechanism 2 and the monitoring mechanism 4 to temporarily block and limit the incomplete connection between the flange 101 and the pipeline system. At the same time, the control unit drives the signal generator to remotely send a signal to remind the staff to check. After receiving the second execution instruction, the control unit controls the input current of the leak prevention device 5 to temporarily seal the expansion body 103. At the same time, the control unit drives the signal generator to remotely send a signal to remind the staff to check.

[0038] The specific working process of this application is as follows: Step 1: Install the flange 101 on the pipeline system through the bolt assembly to facilitate the normal operation of the expansion body 103 in the pipeline system; When the analysis unit determines that there is an incomplete limit between the flange 101 and the pipeline system, the control unit drives the air pump 301 to input current to generate compressed air, which is transported to the compression rubber ring 202 through the hose, driving the compression rubber ring 202 to expand, and temporarily blocking the incomplete limit position between the flange 101 and the pipeline system to prevent liquid leakage and cause certain pollution to the on-site environment; The compressed air generated by the air pump 301 is transported to the leak prevention device 5 through the main delivery pipe 302 and the auxiliary delivery pipe 303, driving the leak prevention device 5 to block the leakage of the output pipeline 102 or drive the output pipeline 102 to vibrate, so as to ensure the removal of the liquid remaining in the internal groove of the output pipeline 102. The compressed air generated by the air pump 301 is transported to the expansion mechanism 2 through the hose to temporarily block the incomplete limit position between the flange and the pipeline system; Step 2: The extrusion column 411 contacts the weight sensor 412 to generate pressure data, and transmits it to the data acquisition end. The data acquisition end transmits the pressure data to the analysis unit. The analysis unit determines whether the connection between the flange 101 and the pipeline system is not completely limited by the change of real-time pressure data. When the analysis unit determines that the connection between the flange 101 and the pipeline system is not completely connected, the control unit drives the electric control lifting column 407 to input current, controls the flange 101 to move toward the pipeline system, increases the extrusion force applied by the flange 101 to the pipeline system, and drives the two to be in a fitting state, which is conducive to achieving the effect of temporarily limiting the flange 101 and the pipeline system, and avoiding liquid leakage during the use of the non-metallic expansion joint 1. Step 3: During the working process of the non-metallic expansion joint 1, the compressed air generated by the air conveying mechanism 3 is conveyed to the inside of the telescopic column 504, driving the telescopic column 504 to be in a stretched state. The telescopic column 504 in the stretched state drives the second hollow ring 505, the annular stretching plate 502 and the rubber ring frame 503 to move toward the expansion body 103. The rubber ring frame 503 is squeezed onto the surface of the expansion body 103, and the rubber ring frame 503 is deformed, driving the air inside the adsorption groove to be discharged, thereby driving the rubber ring frame 503 to be adsorbed on the outer wall of the expansion body 103. At the same time, the air conveying mechanism 3 changes the content of the compressed air inside the telescopic column 504 to And under the action of the spring force of the long spring, the telescopic column 504 is driven to stretch and contract, thereby driving the expansion body 103 to vibrate, so as to facilitate the fall-off of the acidic solution attached to the inner wall of the expansion body 103, avoid the acidic solution from corroding the inner wall of the expansion body 103, and increase the service life of the expansion body 103. When the analysis unit determines that the expansion body 103 is leaking, the air conveying mechanism 3 conveys compressed air to the telescopic column 504, driving each group of rubber ring frames 503 and sealing rubber rings 509 to adhere to the surface of the expansion body 103, and cover the leaking parts on the surface of the expansion body 103, so as to temporarily block the leaking parts of the expansion body 103.
