Description

Technical Field

[0001] This utility model relates to the field of pressure regulating cabinet technology, specifically a pressure regulating cabinet capable of bidirectional metering. Background Technology

[0002] A bidirectional voltage regulator is an electrical measuring device primarily used to measure voltage and current in high-voltage power systems. Its working principle is based on the laws of magnetic induction and Ohm's law. By connecting the electrical quantity to be measured to the measuring port of the voltage regulator, its internal circuitry processes the current and voltage signals, thereby achieving accurate measurement of electrical energy.

[0003] The existing Chinese utility model patent with publication number CN116877922A discloses a two-way gas metering and pressure regulating device, including a pressure regulating cabinet, an inlet pipe, an outlet pipe, a bypass system, and a pressure regulating system. The inlet of the pressure regulator is connected to the pressure regulating pipe through a heat exchange pipe. A heat exchanger is installed on the heat exchange pipe, and the heat exchanger includes a heat exchange cylinder, a circulating heat pump, a circulating pipe, and a heat source box. The pressure regulating pipe passes through and is fixed to the wall of the heat exchange cylinder. The heat exchange cylinder is sleeved and fixed outside the heat exchange pipe, and a cavity for the heat exchange medium to flow is formed between the inner and outer walls of the two. The circulating pipe connects the heat exchange cylinder, the circulating heat pump, and the heat source box in series. The heat exchange cylinder is equipped with a variable diameter mechanism that can change the size of the cavity flow cross-section. This not only improves the de-icing efficiency of the pressure regulator but also effectively reduces energy consumption. At the same time, this invention integrates pressure regulation, filtration, overpressure / underpressure cutoff, metering, and safe venting, resulting in good system coordination and high safety and reliability.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that the bidirectional metering pressure regulating cabinet requires manual adjustment of the valves by workers during use. This necessitates personnel to be on duty at the pressure regulating cabinet to facilitate subsequent valve adjustments, thereby increasing the labor force required. Furthermore, when manually adjusting the valves, workers are prone to fatigue and distraction, which can lead to incomplete valve closure and subsequent gas leaks. All these issues affect the use of the device. Utility Model Content

[0009] An electric ball valve is installed at the upper end of the automatic adjustment component. A rotating structure is installed at the upper end of the electric ball valve. A flow meter is installed on the right side of the electric ball valve. A pressure transmitter is installed on the right side of the flow meter.

[0019] Beneficial effects:

[0020] 1. This utility model, through the design of the overall device, adds a flow meter, electric ball valve, pressure remote transmission meter, and leak alarm to the original pressure regulating cabinet. The pressure remote transmission meter monitors the leakage pressure, facilitating subsequent alarms from the leak alarm to remind personnel to carry out maintenance. It realizes the remote transmission of pressure, flow, and other signals, enabling remote operation of the electric ball valve of the unattended pressure regulating cabinet in the SCADA system. A perimeter warning camera is added to the upper end of the fixed frame in the monitoring and alarm component. The warning camera is connected to the audible and visual alarm to facilitate subsequent alarms and announcements for intrusion. This effectively prevents the need for manual adjustment of valves by workers when using the bidirectional metering pressure regulating cabinet, which would otherwise require personnel to be on duty for subsequent valve adjustments. This would increase the labor force required for manual valve adjustment, and the fatigue and distraction of personnel during manual valve adjustment could lead to incomplete valve closure and subsequent gas leakage.
