Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline exhaust technology, and in particular to an exhaust device for a pipeline system. Background Art
[0002] In related technologies, exhaust devices can be used to regulate the air retained in the pipeline system, and are widely used in engineering fields such as water supply and drainage, shipbuilding, and fluid transportation. With the development of science and technology and the continuous deepening of engineering practice, people's understanding of exhaust devices has improved. People have found that trapping a portion of air in the pipeline system can absorb the energy of the water hammer wave, and use the elasticity of the trapped air to reduce the impact of the water hammer on the pipeline system, thereby protecting the pipeline system. Among them, the exhaust device used in the pipeline system is required to be able to quickly exhaust the air in the early stage of pipeline operation, actively trap a portion of the air after the initial rapid exhaust, and continuously discharge the air precipitated in the pipeline when the pipeline system is in normal operation. It can quickly inhale air when the pipeline system is under negative pressure, so as to improve the stability and reliability of the pipeline system.
[0003] Traditional exhaust devices used in pipeline systems usually use floats to achieve related functions. Specifically, the float is used to block the exhaust port of the exhaust device. When the amount of air in the pipeline is high, the float drops along with the liquid level to release the blockage of the exhaust port, allowing exhaust to be discharged; when the amount of air in the pipeline is low, the float rises along with the liquid level to block the exhaust port; when negative pressure is formed in the pipeline, the float releases the blockage of the exhaust port under the action of the negative pressure, allowing air to be sucked in. However, traditional exhaust devices used in pipeline systems have the problem of the float sticking due to factors such as water rust and van der Waals forces, resulting in the exhaust port of the exhaust device not being effectively blocked when it needs to be blocked, resulting in leakage. If the exhaust port of the exhaust device leaks and cannot be discovered and remedied in time, it will cause great losses. Utility Model Content

[0028] In related technologies, exhaust devices can be used to regulate the air retained in the pipeline system, and are widely used in engineering fields such as water supply and drainage, shipbuilding, and fluid transportation. With the development of science and technology and the continuous deepening of engineering practice, people's understanding of exhaust devices has improved. People have found that trapping a portion of air in the pipeline system can absorb the energy of the water hammer wave, and use the elasticity of the trapped air to reduce the impact of the water hammer on the pipeline system, thereby protecting the pipeline system. Among them, the exhaust device used in the pipeline system is required to be able to quickly exhaust the air in the early stage of pipeline operation, actively trap a portion of the air after the initial rapid exhaust, and continuously discharge the air precipitated in the pipeline when the pipeline system is in normal operation. It can quickly inhale air when the pipeline system is under negative pressure, so as to improve the stability and reliability of the pipeline system.
[0029] Traditional exhaust devices used in pipeline systems usually use floats to achieve related functions. Specifically, the float is used to block the exhaust port of the exhaust device. When the amount of air in the pipeline is high, the float drops along with the liquid level to release the blockage of the exhaust port, allowing exhaust to be discharged; when the amount of air in the pipeline is low, the float rises along with the liquid level to block the exhaust port; when negative pressure is formed in the pipeline, the float releases the blockage of the exhaust port under the action of the negative pressure, allowing air to be sucked in. However, traditional exhaust devices used in pipeline systems have the problem of the float sticking due to factors such as water rust and van der Waals forces, resulting in the exhaust port of the exhaust device not being effectively blocked when it needs to be blocked, resulting in leakage. If the exhaust port of the exhaust device leaks and cannot be discovered and remedied in time, it will cause great losses.
[0030] To this end, it is urgent to optimize the existing exhaust device for the pipeline system to solve the above-mentioned technical problems. The exhaust device for the pipeline system optimized by this application will be described in detail below with reference to the accompanying drawings.
[0031] Reference Figures 1 to 3 According to an embodiment of the present application, an exhaust device for a pipeline system includes a two-position three-way solenoid valve 100, an exhaust component, a detection component and a controller 300.
[0032] Specifically, the two-position three-way solenoid valve 100 has an input end and two output ends, and the exhaust component has two groups. The two groups of exhaust components are arranged one by one at the two output ends of the two-position three-way solenoid valve 100. The exhaust component includes an exhaust pipe 210, a float 220 and a sealing ring 230. The lower end of the exhaust pipe 210 is connected to the output end of the two-position three-way solenoid valve 100. The float 220 can be floated in the exhaust pipe 210. The sealing ring 230 is arranged in the exhaust pipe 210 and is located above the float 220. The sealing ring 230 is used to cooperate with the float 220 to seal the exhaust pipe 210. The detection component is used to detect whether the exhaust component is leaking. The controller 300 is electrically connected to the two-position three-way solenoid valve 100 and the detection component respectively.
[0033] During use, the input end of the two-position three-way solenoid valve 100 is connected to the target pipeline a, and the two-position three-way solenoid valve 100 is controlled to select one of the exhaust components for exhaust. When the detection component detects a leak in the exhaust component being exhausted, the two-position three-way solenoid valve 100 is controlled to select another exhaust component for exhaust. At this time, the flow path corresponding to the leaking exhaust component is disconnected to prevent continued leakage. As can be seen from this, when a leak occurs, the exhaust device for a pipeline system according to the embodiment of the present application can promptly detect and automatically remedy it, thereby helping to reduce losses.
[0034] in, Figure 2The path indicated by the arrow in the middle is the corresponding flow path when one of the exhaust components is exhausting.
[0035] Reference Figures 1 to 3 In some embodiments, the detection assembly includes a connecting tube 410 and a sensor 420. The two ends of the connecting tube 410 are connected to the two exhaust pipes 210 in a one-to-one correspondence, and the ends of the connecting tube 410 are located above the corresponding sealing rings 230. The sensor 420 is disposed within the connecting tube 410 and is electrically connected to the controller 300. The sensor 420 is used to detect whether there is liquid leaking from the exhaust pipe 210 in the connecting tube 410. When a leak occurs, at least part of the leaked liquid will enter the connecting tube 410. When the sensor 420 disposed within the connecting tube 410 detects the liquid, the controller 300 can determine that a leak has occurred in the exhaust assembly being used.
[0036] It should be noted that in some other embodiments, the detection assembly may also include two connecting tubes 410 and two sensors 420, which are not limited here. Specifically, the two connecting tubes 410 are connected to the two exhaust pipes 210 in a one-to-one correspondence, with one end of the connecting tube 410 near the exhaust pipe 210 located above the sealing ring 230. The two sensors 420 are disposed in the two connecting tubes 410 in a one-to-one correspondence and are both electrically connected to the controller 300. The sensors 420 are used to detect whether there is liquid leaking from the exhaust pipe 210 in the connecting tube 410.
[0037] Reference Figures 1 to 3 In some embodiments, the connecting pipe 410 is arranged horizontally to facilitate the leaked liquid to enter the connecting pipe 410.

The end of the connecting pipe 410 is connected to the end cover 240 and connected to the exhaust port 241. The structure is simple and easy to implement.
[0039] It should be noted that, in some other embodiments, the end of the connecting pipe 410 may also be directly connected to the upper portion of the exhaust pipe 210 . In this case, the above-mentioned end cover 240 is not required, and this is not limited here.
[0040] It should be noted that in some embodiments, the sensor 420 is a liquid level sensor. Specifically, the sensor 420 is a photoelectric liquid level sensor. Of course, the sensor 420 can also be other types of liquid level sensors, which are not limited here.
[0041] It should be noted that, in some other embodiments, the sensor 420 may also be a water immersion sensor, which is not limited here.
[0042] It should be noted that, in some of the embodiments, a manual switch valve is provided at the input end of the two-position three-way solenoid valve 100. When a leakage occurs and maintenance is required, the staff arriving at the site can disconnect the flow path between the input end of the two-position three-way solenoid valve 100 and the target pipeline a through the manual switch valve to facilitate maintenance.
[0043] Reference Figures 1 to 3 In some embodiments, the manual switch valve is a gate valve 500, which includes a valve body 510, a gate plate 520, a valve stem 530 and a handwheel 540. The valve stem 530 is threadedly connected to the valve body 510, the gate plate 520 is connected to one end of the valve stem 530 and is located inside the valve body 510, and the handwheel 540 is connected to the other end of the valve stem 530 and is located outside the valve body 510. When the handwheel 540 is rotated, the gate plate 520 can be driven to move axially along the valve stem 530 to realize the opening and closing of the valve body 510.
[0044] It should be noted that, in some other embodiments, the manual switch valve may also be a ball valve, a stop valve or other types of switch valves, which are not limited here.
[0045] Reference Figure 2 and Figure 3 In some embodiments, a limiting bracket 250 is provided in the exhaust pipe 210. The limiting bracket 250 is located below the float 220 and is used to support the float 220 to prevent the float 220 from detaching from the exhaust pipe 210 from the lower end of the exhaust pipe 210, which is beneficial to improving the stability and reliability of the float 220 during operation.
[0046] It should be noted that in some embodiments, the controller 300 has a remote communication module (not shown in the figure), which is used to transmit information to a fixed terminal or a mobile terminal, so that when a leak occurs, the staff can be notified in a timely manner so that the staff can perform maintenance in a timely manner. Specifically, the remote communication module can use wireless transmission or wired transmission, which is not limited here. The specific structure and working principle of the remote communication module are well known in the art and are not described in detail here.
[0047] It should be noted that in some embodiments, the controller 300 further includes a positioning module (not shown) to enable the remote communication module to transmit the location information of the leak to a fixed terminal or a mobile terminal, so that personnel can quickly reach the leak. The specific structure and working principle of the positioning module are well known in the art and will not be described in detail here.
