Description

Technical Field

[0001] This utility model relates to the technical field of pressure regulating stations, and in particular to an ESD valve alarm device for pressure regulating stations. Background Technology

[0002] An ESD valve (Emergency Shutdown Valve) is a critical safety device that is widely used in natural gas pressure regulating stations.

[0003] The existing ESD valves at the inlet of the pressure regulating station are equipped with two solenoid valves, which are pneumatically actuated. They open when energized and close when de-energized. During normal unit operation, they remain open, and in emergencies, they close to ensure the safety of the unit equipment. If an ESD valve malfunctions during unit operation, causing the solenoid valve to close accidentally, it will cut off the natural gas supply, directly threatening the safe and stable operation of the unit. In a power cut-off test on the ESD valves, firstly, power supply A was disconnected, causing solenoid valve 1 to de-energize and activate; then power supply B was disconnected, causing solenoid valve 2 to de-energize and activate. It was found that both ESD valves draw their 24V power from the same power supply. When the electrical power is lost, both solenoid valves 1 and 2 de-energize and activate simultaneously, causing the ESD valves to malfunction. When an ESD valve malfunction occurs, the lack of a power loss monitoring device leads to slow response from operators, affecting unit operation.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:

[0005] When existing ESD valves fail, there is a lack of power loss monitoring devices, resulting in slow response from staff and impacting unit operation. Utility Model Content

[0012] Beneficial effects:

[0013] This utility model provides an ESD valve alarm device for a voltage regulating station. In use, it consists of two circuits to reduce the occurrence of power outages in the ESD valves. The first circuit transmits power from the voltage regulating station's main power supply to an uninterruptible power supply (UPS), ensuring the ESD valve continues to operate for a period even in the event of a sudden power failure. The UPS supplies power to a first power converter via main switch 1 and main switch 2.

The second circuit transmits power from the voltage regulating station's safety power supply via backup switch 1 to a dual-path switching device and backup switch 2. The dual-path switching device is connected to main switch 1, and backup switch 2 is connected to the second power converter. The second power converter supplies power to the first and second ESD valves via main switch 4 and backup switch 3. When the first and second power converters lose power, a first and second wireless transmitter transmit a power failure signal to the work area to alert personnel. This type of ESD valve alarm device for voltage regulating stations makes it less prone to power supply failures, and allows for a faster response from operators to power supply failures, effectively ensuring unit operation.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] This embodiment provides an ESD valve alarm device for a pressure regulating station. Please refer to [link / reference]. Figure 1-2 As shown, the system includes a power distribution cabinet 100, an ESD valve assembly 200, and an alarm assembly 300. The power distribution cabinet 100 includes a cabinet body 110, an uninterruptible power supply (UPS) 131, a main switch 132, a main switch 133, a first power converter 134, a main switch 135, a main switch 136, a backup switch 137, a dual-path switching device 138, a backup switch 139, a second power converter 140, a backup switch 141, and a backup switch 142. The UPS 131 is installed inside the cabinet body 110 and is used to connect to the main power supply of the voltage regulating station. The main switch 132 is connected to the UPS 131, the main switch 133, and the dual-path switching device 138. The main switch 133 is connected to the first power converter 134, and the first power converter 134 is connected to the main switch 135 and the backup switch 141. Connections: The first protection switch 137 is connected to the safety power supply of the voltage regulating station, and it is also connected to the dual-path switching device 138 and the second protection switch 139. The second protection switch 139 is connected to the second power converter 140, which is connected to the main fourth switch 136 and the fourth protection switch 142. The ESD valve assembly 200 includes a first ESD valve 210 and a second ESD valve 220. The first ESD valve 210 is connected to the main third switch 135 and the fourth protection switch 142, and the second ESD valve 220 is connected to the main fourth switch 136 and the third protection switch 141. The alarm assembly 300 includes a first wireless transmitter 310 and a second wireless transmitter 320. The first wireless transmitter 310 is connected to the first power converter 134, and the second wireless transmitter 320 is connected to the second power converter 140.

[0028] Specifically, the distribution cabinet 100 is used to install electrical components. The cabinet body 110 is welded from steel. Main switch 132, main switch 133, first power converter 134, main switch 135, main switch 136, backup switch 137, dual-path switching device 138, backup switch 139, second power converter 140, backup switch 141, and backup switch 142 are all located inside the cabinet body 110 and are divided into two circuits. The first circuit transmits power from the main power supply of the voltage regulating station to the uninterruptible power supply 131. The uninterruptible power supply 131 ensures that the ESD valve can continue to operate for a period of time even in the event of a sudden power outage. The uninterruptible power supply 131 supplies power to the first power converter 134 through main switch 132 and main switch 133, converting the 220V voltage into a stable 24V voltage, thereby reducing the failure rate of the ESD valve. The first power converter 134... In the first circuit, power is supplied to the first ESD valve and the second ESD valve via the main three-switch 135 and the fourth-protection switch 142. Simultaneously, the first power converter 134 is connected to the first wireless transmitter 310. In the second circuit, the safety power supply from the voltage regulating station is transmitted via the first protection switch 137 to the dual-path switching device 138 and the second protection switch 139. The dual-path switching device 138 is used to switch the circuit operation mode and is also connected to the main one-switch 132. The second protection switch 139 is connected to the second power converter 140. The second power converter 140 supplies power to the first ESD valve 210 and the second ESD valve 220 via the main four-switch 136 and the third-protection switch 141. When the first power converter 134 and the second power converter 140 are out of power, the first wireless transmitter 310 and the second wireless transmitter 320 transmit a power failure signal to the work room to alert the staff. The uninterruptible power supply 131 ensures that the first ESD valve 210 and the second ESD valve 220 can continue to operate for a period of time in the event of a sudden power loss. At the same time, the parallel connection of the two power supplies also reduces the risk of failure of the first ESD valve 210 and the second ESD valve 220. When the first power converter 134 and the second power converter 140 are out of power, they transmit power failure signals to the work room through the first wireless transmitter 310 and the second wireless transmitter 320, respectively, to alert the staff.

[0029] In this embodiment, the first power converter 134 is connected to a main five-way switch 143, which is connected to the first wireless transmitter 310. The second power converter 140 is connected to a protection five-way switch 144, which is connected to the second wireless transmitter 320.

[0030] Specifically, the main five-way switch 143 is used to control whether the first wireless transmitter 310 is enabled, and the protection five-way switch 144 is used to control whether the second wireless transmitter 320 is enabled.

[0031] In this embodiment, the cabinet 110 is connected to a first audible and visual alarm 330 and a second audible and visual alarm 340 respectively; the first audible and visual alarm 330 is connected to the main five-way switch 143, and the second audible and visual alarm 340 is connected to the security five-way switch 144.

[0032] Specifically, the first audible and visual alarm 330 and the second audible and visual alarm 340 are respectively installed on the cabinet 110, so that on-site staff can easily know whether the power supply is missing, and it is also convenient for operators to identify which power supply is missing.

[0033] In this embodiment, the cabinet body 110 is connected to a cabinet door 120, and the cabinet door 120 is provided with a handle 121.

[0034] Specifically, cabinet door 120 is used to seal and open cabinet body 110, and handle 121 is provided to facilitate the use of cabinet door 120.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
