Description

Technical Field

[0001] This application relates to the field of industrial fluid technology, and particularly to a plug-in purging device. Background Art

[0002] During the use, manufacturing, installation, or maintenance of pipelines, impurities, dust, and other substances that are easily attached and blocked are often generated. Therefore, it is necessary to implement on-line purging in industrial pipelines in a timely manner to remove foreign matters such as impurities, rust, welding slag, and sediment generated during the use, manufacturing, installation, or maintenance of the pipelines before putting them into use. However, if the throttle element of the flowmeter is directly installed on the pipeline during the purging process, the impurities purged down are easily attached to the throttle element, and a lot of dirt, impurities, sediments, etc. will be generated on the front and rear end faces of the throttle element. In severe cases, the holes of the throttle element may be blocked by impurities. These dirt will be repeatedly flushed in the pipeline, which is likely to cause deviation in the measurement of the flowmeter and seriously affect the accuracy of the flowmeter measurement. At the same time, the pressure impact generated during the purging process is likely to cause damage to the throttle element. Summary of the Invention

[0007] Wherein, the purging member is detachably connected to the two connecting flanges. A through hole is provided in the middle of the purging member, and pressure tapping holes are provided on the side walls of the two connecting flanges. The pressure tapping holes are communicated with the through hole so that the gas used for purging the pipeline is respectively injected into the pipeline through the pressure tapping holes and the through hole to purge the inside of the pipeline.

[0008] In a possible implementation manner, the main body of the purging member is in a circular ring-shaped sheet structure.

[0031] Figure 1 An exploded view of the structure of the plug-in purge device showing an embodiment of the present application; Figure 2 A main body structure diagram of the plug-in purge device showing an embodiment of the present application; Figure 3 A front view of the plug-in purge device showing an embodiment of the present application; Figure 4 A side view of the plug-in purge device showing an embodiment of the present application; Figure 5 A main body structure diagram of the purge member 200 showing an embodiment of the present application; Figure 6 A front view of the purge member 200 showing an embodiment of the present application; Figure 7The main structure diagram of the throttle member 600 is shown; Figure 8 The assembly diagram of the throttle member 600 is shown. This plug-in purging device is suitable for being installed on the pipeline 300 to realize purging of the pipeline 300, and includes: two connecting flanges 100 and a purging member 200; the two connecting flanges 100 are arranged oppositely and detachably connected, and one side of each of the two connecting flanges 100 facing away from each other is suitable for being connected to the pipe orifice of the pipeline 300; the shape of the purging member 200 matches the throttle member installed on the pipeline 300, and the purging member 200 is suitable for being installed between the two connecting flanges 100 to replace the throttle member 600 during the purging process of the pipeline 300; wherein, the purging member 200 is detachably connected to the two connecting flanges 100, a through hole 210 is opened in the middle of the purging member 200, and pressure tapping holes 110 are opened on the side walls of the two connecting flanges 100, and the pressure tapping holes 110 are communicated with the through hole 210, so that the gas used for purging the pipeline 300 respectively passes through the pressure tapping holes 110 and the through hole 210 and is injected into the pipeline 300 to purge the pipeline 300.

[0032] Here, it should be noted that the two connecting flanges 100 are respectively a positive pressure side connecting flange 100 and a negative pressure side connecting flange 100, and the two connecting flanges 100 are tightly connected to the industrial pipeline 300 to ensure that the concentricity between the connecting flanges 100 and the industrial pipeline 300 is consistent; a purging member 200 or a throttle member 600 is suitable for being installed between the two connecting flanges 100. When it is necessary to purge the pipeline 300, the purging member 200 is installed between the connecting flanges 100, and nitrogen or steam is introduced into the pipeline 300 through the pressure tapping holes 110. The gas flows through the purging member 200 and flows through the through hole 210 in the middle of the purging member 200, so as to realize the cleaning and purging of impurities and dirt in the pipeline 300. When the purging is completed, the two connecting flanges 100 are disassembled, the purging member 200 is removed, and then the throttle member 600 is installed and reset between the two connecting flanges 100. By mutually replacing the purging member 200 and the throttle member 600, the orderly progress of the purging process is ensured and it is ensured that the throttle member 600 is not in the pipeline 300 during the purging process, and foreign matters such as impurities, rust, welding slag, and sediment purged off will not adhere to the throttle member 600. While ensuring the purging effect, this application also protects the performance of the flowmeter, extends its service life, improves the measurement accuracy, reduces the shutdown time of the industrial pipeline 300, improves the production efficiency, and the overall operation is simple, not prone to safety accidents, greatly reduces the unsafe factors, and can be reused.

[0033] In a possible implementation manner, the main body of the purging member 200 is in a circular ring-shaped sheet structure. As Figure 5As shown, the through hole 210 in the middle of the purging member 200 is circular in structure, and the diameter of the through hole 210 of the purging member 200 is the same as the inner diameter of the connecting flange 100. Such a setting maximizes the size of the through hole 210 of the purging member 200 to improve the gas flow efficiency inside the purging member 200, avoiding the purging member 200 from blocking the gas flow and also preventing foreign matters such as impurities, rust, welding slag, and sediment purged down from adhering to the purging member 200.

[0034] In a possible implementation manner, a taking portion 220 is provided on the outer side wall of the purging member 200. As Figure 5 shown, the taking portion 220 protrudes on the outer side wall of the purging member 200. When disassembling or installing the purging member 200, the taking portion 220 can improve the convenience of taking and placing the purging member 200, and during the fixed installation process of the two connecting flanges 100, the purging member 200 can be prevented from shifting or falling off by holding the taking portion 220 by hand.

[0035] Furthermore, the thickness of the purging member 200 is the same as the thickness of the throttling member 600 to facilitate the random replacement of the purging member 200 and the throttling member 600 between the two connecting flanges 100 and ensure the connection tightness between the two connecting flanges 100 and the purging member 200 or the throttling member 600.

[0036] In a possible implementation manner, it further includes: two gaskets 400. The main bodies of the two gaskets 400 are circular ring-shaped structures, and the two gaskets 400 are respectively arranged between the two connecting flanges 100 and the purging member 200. Here, it should be noted that the two gaskets 400 are arranged on the front and rear end faces of the purging member 200 to improve the connection sealing performance between the connecting flange 100 and the purging member 200, avoiding the purging gas from leaking and causing the internal air pressure of the pipeline 300 to be too low, resulting in incomplete purging. Furthermore, when the throttling member 600 is placed between the two connecting flanges 100, the setting of the gaskets 400 can also improve the sealing performance between the throttling member 600 and the flange, ensuring that the liquid in the pipeline 300 will not overflow from the connecting flange 100.

[0037] Furthermore, the outer diameter of the gasket 400 is the same as the outer diameter of the purging member 200, and the inner diameter of the gasket 400 is the same as the inner diameter of the purging member 200. This avoids the gasket 400 from blocking the gas flow and also prevents foreign matters such as impurities, rust, welding slag, and sediment purged down from adhering to the gasket 400.

[0038] In a possible implementation manner, a gasket groove 130 is provided on the side of the connecting flange 100 connecting the gasket 400. As Figure 1As shown, the gasket groove 130 has a circular groove structure. The gasket groove 130 is matched with the gasket 400, and the gasket 400 is embedded in the gasket groove 130 to improve the fixing stability of the gasket 400 and prevent the gasket 400 from falling off, which may cause poor sealing between the connecting flange 100 and the purging member 200.

[0039] In a possible implementation, the connecting flange 100 and the pipeline 300 are fixedly connected by welding.

[0040] In a possible implementation, two connecting flanges 100 are detachably connected by more than two bolt assemblies. Here, it should be noted that more than two bolt assemblies are suitable for fixedly connecting or disassembling between the two connecting flanges 100, and can ensure the stability of the connection structure between the two connecting flanges 100, preventing the throttling member 600 or the purging member 200 from being fixed unstably.

[0041] Further, the bolt assembly includes: a fully threaded stud 500 and two matching nuts 510. The fully threaded stud 500 passes through the bolt holes 120 of the two connecting flanges 100, and the two nuts 510 are screwed tightly on the fully threaded stud 500. The two nuts 510 are respectively in close contact with the opposite sides of the two connecting flanges 100 to fix the two connecting flanges 100.

[0042] Furthermore, there are 12 bolt assemblies. Correspondingly, each connecting flange 100 is provided with 12 bolt holes 120. The fully threaded studs 500 of the 12 bolt assemblies respectively pass through the 12 bolt holes 120, and then are locked with nuts 510 to improve the fixing stability between the two connecting flanges 100.

[0043] The above has described the embodiments of the present application. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the disclosed embodiments.
