Description

Technical Field

[0001] This application relates to the technical field of gas pressure regulating equipment components, and in particular to a venting alarm for a gas pressure regulating station. Background Technology

[0002] Currently, for traditional gas pressure regulating stations, the vent valve, after opening due to overpressure, is usually only discovered during manual on-site inspections or after the shut-off valve has been shut off and the gas path is found to be blocked. By this time, the vent valve has already been releasing gas for some time, making it difficult for maintenance personnel to detect the venting immediately, resulting in a delayed response. Furthermore, due to varying operating conditions and environmental factors, the installation of intelligent vent valves in older gas pressure regulating stations is prohibitively expensive, posing significant challenges to their safe and stable operation. Utility Model Content

[0003] To address the aforementioned problems, this application provides a venting alarm for gas pressure regulating stations. With its ingenious design and simple structure, this application solves the problem of delayed manual response after the venting valve is opened in traditional gas pressure regulating stations. Through real-time monitoring of the venting status and timely alarm notification via a remote platform, it accurately locates the venting position, significantly reducing manual inspections and maintenance time after overpressure venting, thereby substantially lowering labor costs. This provides an efficient solution for the safe operation of gas pressure regulating stations, combining technological innovation with engineering practicality. The technical solution adopted in this application is as follows:

[0004] A venting alarm for a gas pressure regulating station includes: a valve body, a valve stem, a valve disc, a magnetic sensor, and a magnetic component;

[0005] The valve housing has a hollow cavity structure with an air inlet at the bottom, an air outlet on the side, and a guide hole at the top. The valve stem passes through the guide hole, and the valve disc is mounted on the bottom end of the valve stem. A spring is fitted over the valve stem and clamped between the guide hole and the valve disc. A magnetic sensor is mounted on the side of the valve housing to monitor the displacement of the valve disc. A magnetic component is mounted on the upper side of the valve disc or on the valve stem, and the magnetic component can move synchronously with the valve disc. The movement of the magnetic component can trigger the magnetic sensor.

[0006] Under normal conditions, no airflow enters the valve housing from the air inlet, and the valve disc remains stationary at the air inlet position, blocking the air inlet. When the airflow pushes the valve disc upward, the magnetic component moves upward to trigger the magnetic sensor.

[0007] By incorporating a magnetic component and a magnetic sensor, the magnetic component moves synchronously with the valve disc. When the gas pipeline experiences overpressure, the airflow pushes the valve disc upwards, opening the inlet and allowing the overpressured gas to escape from the outlet, thus reducing the gas pressure within the pipeline. The movement of the valve disc causes the magnetic component to move synchronously, and the magnetic sensor detects this movement and generates a trigger signal. The magnetic sensor is connected to a wireless transmission module, which transmits the trigger signal to the control platform. The control platform is used to monitor the venting status of the venting alarm in real time and issue alarm messages.

[0008] This venting alarm has a simple structure and strong versatility, lacking the complex structure of current intelligent venting valves. It boasts low production costs and is suitable for safety upgrades at older stations, applicable to natural gas and other non-corrosive gases. By combining it with a wireless remote transmission module, this venting alarm can be used in situations requiring signal monitoring of safety device emissions, such as venting valves, relief valves, pilot safety valves, pilot-operated safety valves, and accelerator emissions for monitoring and intervention. This significantly reduces the safety upgrade costs for older stations.

[0009] This venting alarm solves the problem of delayed manual response after the venting valve is opened in traditional gas pressure regulating stations. Through a remote control platform, the venting status of the venting alarm can be monitored in real time and alarm information can be issued in a timely manner. The venting location can be accurately located, which can greatly reduce manual inspection and maintenance time after overpressure venting, significantly reduce labor costs, and provide an efficient solution for the safe operation of gas pressure regulating stations. It combines technological innovation with engineering practicality.

[0010] In some embodiments, the magnetic element is circular and coaxially arranged with the valve stem.

[0011] By designing the magnetic component as circular and coaxial with the valve stem, the magnetic sensor can be triggered as long as the magnetic component moves vertically, regardless of whether it rotates. In other words, this design ensures that the magnetic sensor can be stably triggered when the magnetic component moves vertically, thus improving the sensitivity and accuracy of the magnetic sensor being triggered by the magnetic component.

[0012] In some embodiments, an indicator cover is also included, one end of which is mounted on the valve housing and coaxially arranged with the valve stem, and the top end of the valve stem is located inside the indicator cover; the indicator cover has a transparent portion through which it is possible to observe whether the valve stem has moved vertically.

[0013] By installing an indicator cover, the valve stem can be protected from accidental activation. A transparent section on the indicator cover allows manual inspection to observe whether the valve stem is moving, thus determining whether release is in progress.

[0014] In some embodiments, the indicator housing is provided with scale markings distributed vertically at intervals, through which the distance the valve stem has moved vertically can be determined.

[0015] By setting scale markings, the displacement of the valve stem can be observed during manual inspection, thereby enabling the determination of the overpressure level in the pipeline.

[0016] In some embodiments, the top of the indicator housing is covered with an indicator cover, and the valve housing is provided with a vent hole that communicates with the internal space of the indicator housing.

[0017] By sealing the top of the indicator cover, rainwater, dust, and other debris can be prevented from entering the indicator cover, thus avoiding interference with the normal operation of the alarm and extending its service life. A vent connects the external environment to the internal space of the indicator cover, allowing the valve stem to move freely within the cover.

[0018] In some embodiments, the inner wall of the valve housing is provided with an annular recess, the annular recess is coaxially arranged with the guide hole, and the end of the spring away from the valve disc abuts against the annular recess.

[0019] By setting an annular recess, one end of the spring can be limited to prevent it from shifting, thus avoiding jamming and ensuring the spring functions stably.

[0020] In some embodiments, the valve disc has an annular protrusion on the side near the magnetic element, the annular protrusion being located at the outer peripheral edge of the valve disc and surrounding the outer periphery of the magnetic element.

[0021] By setting an annular convex edge, which is located at the outer periphery of the valve disc and surrounds the outer periphery of the magnetic component, the magnetic component can limit the deformation of the valve disc, reduce the risk of valve disc deformation, and thus avoid affecting the sensitivity and accuracy of the discharge alarm due to valve disc deformation.

[0022] The gas pressure regulating station venting alarm provided in this application has at least one of the following beneficial effects:

[0023] 1. This application provides a venting alarm for a gas pressure regulating station. By incorporating a magnetic component and a magnetic sensor, the magnetic component moves synchronously with the valve disc. When the gas pipeline experiences overpressure, the airflow pushes the valve disc upwards, opening the inlet and allowing the overpressured airflow to escape from the outlet, thereby reducing the gas pressure within the pipeline. The movement of the valve disc causes the magnetic component to move synchronously, and the magnetic sensor detects this movement and generates a trigger signal. The magnetic sensor is connected to a wireless transmission module, and the trigger signal generated by the magnetic sensor can be transmitted to a control platform via the wireless transmission module. The control platform is used to monitor the venting status of the venting alarm in real time and issue alarm information.

[0024] This venting alarm has a simple structure and strong versatility, lacking the complex structure of current intelligent venting valves. It boasts low production costs and is suitable for safety upgrades at older stations, applicable to natural gas and other non-corrosive gases. By combining it with a wireless remote transmission module, this venting alarm can be used in situations requiring signal monitoring of safety device emissions, such as venting valves, relief valves, pilot safety valves, pilot-operated safety valves, and accelerator emissions for monitoring and intervention. This significantly reduces the safety upgrade costs for older stations.

[0025] This venting alarm solves the problem of delayed manual response after the venting valve is opened in traditional gas pressure regulating stations. Through a remote control platform, the venting status of the venting alarm can be monitored in real time and alarm information can be issued in a timely manner. The venting location can be accurately located, which can greatly reduce manual inspection and maintenance time after overpressure venting, significantly reduce labor costs, and provide an efficient solution for the safe operation of gas pressure regulating stations. It combines technological innovation with engineering practicality.

[0026] 2. The gas pressure regulating station venting alarm provided in this application designs the magnetic component as circular and coaxial with the valve stem, so that the magnetic sensor can be triggered as long as the magnetic component moves vertically, regardless of whether the magnetic component rotates or not. In other words, this design ensures that the magnetic sensor can be stably triggered when the magnetic component moves vertically, thereby improving the sensitivity and accuracy of the magnetic component triggering the magnetic sensor.

[0027] 3. The venting alarm for a gas pressure regulating station provided in this application, by setting an indicator cover, can protect the valve stem and prevent it from being accidentally triggered. By setting a transparent part on the indicator cover, it is possible to observe whether the valve stem is moving during manual inspection, thereby determining whether venting is in progress.

[0028] 4. The gas pressure regulating station venting alarm provided in this application can observe the displacement of the valve stem during manual inspection by setting scale marks, thereby judging the overpressure level of the pipeline.

[0029] 5. The gas pressure regulating station venting alarm provided in this application, by sealing the top of the indicator cover, can prevent rainwater, dust and other debris from entering the indicator cover, avoiding the impact of debris on the normal use of the venting alarm and extending its service life. By providing a vent hole, the external environment is connected to the internal space of the indicator cover, allowing the valve stem to move freely within the indicator cover.

[0030] 6. The gas pressure regulating station venting alarm provided in this application can limit one end of the spring by setting an annular concave platform, preventing the spring from deviating and avoiding the spring from getting stuck, so that the spring can function stably.

[0031] 7. The gas pressure regulating station venting alarm provided in this application has an annular convex edge located at the outer periphery of the valve disc and enclosing the outer periphery of the magnetic component. In this way, the magnetic component can limit the deformation of the valve disc, reduce the risk of valve disc deformation, and thus avoid affecting the sensitivity and accuracy of the venting alarm due to valve disc deformation.

[0042] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0043] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0044] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0045] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] refer to Figures 1-6This application provides a venting alarm for a gas pressure regulating station, comprising: a valve housing 1, a valve stem 2, a valve disc 3, a magnetic sensor 5, and a magnetic component 6; the valve housing 1 has an internal cavity structure, with an air inlet 11 at the bottom, an air outlet 12 on the side, and a guide hole 13 at the top; the valve stem 2 passes through the guide hole 13, the valve disc 3 is installed at the bottom end of the valve stem 2, and a spring 4 is sleeved on the valve stem 2, the spring 4 being clamped between the guide hole 13 and the valve disc 3; the magnetic sensor 5 is installed on the side of the valve housing 1 to monitor the displacement of the valve disc 3; the magnetic component 6 is installed on the upper side of the valve disc 3 or on the valve stem 2, and the magnetic component 6 can move synchronously with the valve disc 3, triggering the magnetic sensor 5 when the magnetic component 6 moves;

[0048] Under normal conditions, no airflow enters the valve body 1 from the air inlet 11, and the valve disc 3 is stationary at the air inlet 11 and blocks the air inlet 11; when the airflow pushes the valve disc 3 upward, the magnetic component 6 will move upward to trigger the magnetic sensor 5.

[0049] Specifically, this venting alarm is suitable for situations where signal monitoring of emission phenomena from safety devices is required, such as venting valves, relief valves, pilot-operated safety valves, pilot-operated safety valves, and accelerator emissions used for monitoring and intervention. This application uses the monitoring of venting valve emissions as an example for illustration, with reference to... Figure 7 The venting alarm is installed on a branch pipe or pressure tap of the venting pipeline at the rear end of the venting valve. When the venting valve vents due to overpressure, the gas in the pipeline will enter the valve body 1 through the air inlet 11, pushing the valve disc 3 to move upward. The magnetic component 6 will move upward accordingly, triggering the magnetic sensor 5 to transmit the movement signal of the valve disc 3 to the control platform through the wireless remote transmission module. Then the control platform will issue an alarm message, thus completing the venting alarm.

[0050] Understandably, by setting up the magnetic component 6 and the magnetic sensor 5, the magnetic component 6 can move synchronously with the valve disc 3. When the gas pipeline is overpressurized, the airflow will push the valve disc 3 upward, thereby opening the air inlet 11 and allowing the overpressurized airflow to be discharged from the air outlet 12, thus reducing the gas pressure in the pipeline. When the valve disc 3 moves, it will drive the magnetic component 6 to move synchronously. The magnetic sensor 5 can sense the movement of the magnetic component 6 and generate a trigger signal. The magnetic sensor 5 is connected to a wireless remote transmission module. The trigger signal generated by the magnetic sensor 5 can be transmitted to the control platform through the wireless remote transmission module. The control platform is used to monitor the venting status of the venting alarm in real time and issue alarm information.

[0051] It is important to note that this venting alarm has a simple structure, strong versatility, and lacks the complex structure of current intelligent venting valves. It has low production costs and is suitable for safety upgrades at older stations, as well as for natural gas and other non-corrosive gases. By combining it with a wireless remote transmission module, this venting alarm can be used in situations requiring signal monitoring of emission phenomena from safety devices, such as venting valves, relief valves, pilot safety valves, pilot-operated safety valves, and accelerator emissions for monitoring and intervention. This significantly reduces the safety upgrade costs for older stations.

[0052] Notably, this venting alarm solves the problem of delayed manual response after the venting valve is opened in traditional gas pressure regulating stations. Through a remote control platform, it enables real-time monitoring of the venting status and timely alarm issuance, accurately locating the venting point and improving the efficiency of overpressure venting investigation. This significantly reduces manual inspections and post-overpressure venting maintenance time, substantially lowering labor costs and providing an efficient solution for the safe operation of gas pressure regulating stations. It combines technological innovation with engineering practicality, offering a solution to help gas companies upgrade their operation and maintenance model from "passive emergency repair" to "proactive prevention."

[0053] refer to Figures 2-5 In one embodiment, the magnetic element 6 is circular and coaxially arranged with the valve stem 2. By designing the magnetic element 6 as circular and coaxial with the valve stem 2, the magnetic sensor 5 can be triggered as long as the magnetic element 6 moves vertically, regardless of whether the magnetic element 6 rotates. In other words, this design ensures that the magnetic sensor 5 can be stably triggered when the magnetic element 6 moves vertically, thus improving the sensitivity and accuracy of the magnetic element 6 in triggering the magnetic sensor 5.

[0054] refer to Figures 1-4 In one embodiment, the venting alarm further includes an indicator housing 7, one end of which is mounted on the valve housing 1 and coaxially arranged with the valve stem 2, the top end of which is located inside the indicator housing 7; the indicator housing 7 is provided with a transparent portion (not shown in the figure), through which it is possible to observe whether the valve stem 2 has moved vertically.

[0055] It is easy to understand that by setting the indicator cover 7, the valve stem 2 can be protected and prevented from being accidentally touched. By setting a transparent part on the indicator cover 7, it is possible to observe whether the valve stem 2 is moving during manual inspection, and thus determine whether it is releasing gas.

[0056] refer to Figures 1-6 In one embodiment, the indicator housing 7 is provided with vertically spaced scale marks (not shown in the figure), which can be used to determine the distance the valve stem 2 has moved vertically. By setting the scale marks, the displacement of the valve stem 2 can be observed during manual inspection, thereby enabling the determination of the overpressure level in the pipeline.

[0057] refer to Figures 1-4 In one embodiment, the top of the indicator housing 7 is covered with an indicator cover 8, and the valve housing 1 is provided with a vent hole 9, which communicates with the internal space of the indicator housing 7.

[0058] Understandably, by covering the top of the indicator cover 8 with the indicator housing 7, the indicator cover 8 can prevent rainwater, dust, and other debris from entering the indicator housing 7, thus avoiding the impact of debris on the normal use of the alarm and extending the service life of the alarm. By providing a vent 9, the vent 9 connects the external environment with the internal space of the indicator housing 7, allowing the valve stem 2 to move freely within the indicator housing 7.

[0059] refer to Figures 2-4 In one embodiment, an annular recess 14 is provided on the inner wall of the valve housing 1. The annular recess 14 is coaxially arranged with the guide hole 13, and the end of the spring 4 away from the valve disc 3 abuts against the annular recess 14. By providing the annular recess 14, one end of the spring 4 can be limited to prevent the spring 4 from shifting, avoid the spring 4 from getting stuck, and make the spring 4 function stably.

The annular protrusion 31 is located at the outer peripheral edge of the valve disc 3 and is wrapped around the outer periphery of the magnetic element 6.

[0061] It should be noted that by setting an annular convex edge 31, which is located at the outer peripheral edge of the valve disc 3 and surrounds the outer periphery of the magnetic component 6, the magnetic component 6 can limit the deformation of the valve disc 3, reduce the risk of deformation of the valve disc 3, and thus avoid affecting the sensitivity and accuracy of the discharge alarm due to the deformation of the valve disc 3.

[0062] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
