Description

Technical Field

[0001] The utility model relates to the technical field of metering skids, in particular to a gas pressure regulating and metering skid. Background Art

[0002] In the process of natural gas transmission and distribution, pressure regulation and metering are two key links. Pressure regulating equipment is used to adjust high-pressure natural gas to a pressure suitable for downstream use, ensuring that natural gas is transported and used under safe and stable pressure conditions.

[0003] Metering equipment is used to accurately measure the flow of natural gas for trade settlement and usage monitoring. Currently, natural gas pressure regulation and metering are usually distributed in different equipment and locations, requiring complex pipeline connections and multiple installations, which not only increases engineering costs and installation difficulty, but also increases leakage risks and maintenance difficulties. Therefore, it is necessary to redesign the gas pressure regulating and metering skid to address the above issues. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-2 The gas pressure regulating and metering skid comprises a flange ball valve 1, a filter 2, a flange ball valve 2 3, a turbine flowmeter 1 4, a turbine flowmeter 2 5, a pressure regulator 6, a flange ball valve 3 7, a relief valve 8, an intake pipe 9, and an exhaust pipe 10. One end of the intake pipe 9 is connected to a natural gas input source, the filter 2 is installed on the intake pipe 9, the turbine flowmeter 4 is installed downstream of the filter 2, and the pressure regulator 6 is connected downstream of the turbine flowmeter 4.

[0020] A branch pipe is installed on the intake pipe 9, and a flange ball valve 23 and a turbine flowmeter 25 are installed on the branch pipe path. The turbine flowmeter 25 is located downstream of the flange ball valve 23. A supporting frame including a mounting base and a fixed bracket is installed below the flange ball valve 1. The mounting base is used to be fixed on the ground, and the fixed bracket is used to support various pipelines and equipment. The flange ball valve 3 7 is connected downstream of the pressure regulator 6, and the flange ball valve 3 7 is connected to the exhaust pipe 10. The turbine flowmeter 1 4 and the turbine flowmeter 2 5 are both equipped with a data acquisition module. The data acquisition module is used to monitor the flow data in real time and transmit the data to the remote monitoring system through the data transmission module. The pressure regulator 6 is equipped with a remote control device.

[0021] In the utility model, one end of the gas pressure regulating and metering skid is connected to the natural gas input source, and the natural gas is introduced into the device through the pipeline. The natural gas first passes through the filter 2 installed on the inlet pipe 9, which is used to remove impurities and particulate matter in the gas to ensure the safe operation of subsequent equipment and pipelines. The natural gas passing through the filter 2 will flow to the turbine flowmeter 4. The turbine flowmeter 4 measures the gas flow passing through the internal turbine speed and transmits the data to the data acquisition module for monitoring and recording. The natural gas after flowing through the turbine flowmeter 4 then enters the pressure regulator 6. The pressure regulator 6 is used to adjust the pressure of the gas to reach a set stable value. The set value of the pressure regulator can be adjusted in real time by a remote control device to adapt to different usage requirements. The branch pipe on the inlet pipe 9 provides another flow measurement method. A flange ball valve 23 and a turbine flowmeter 25 are installed on the branch pipe path. The secondary flow measurement device is also equipped with a data acquisition module for monitoring secondary flow data. The turbine flowmeter 25 is installed downstream of the flange ball valve 23. The opening and closing of the secondary flow can be adjusted by controlling the flange ball valve 23. The natural gas after pressure regulation by the pressure regulator 6 will flow to the flange ball valve 37, and finally discharged to the required output pipe network through the exhaust pipe 10. When emergency discharge is required, the relief valve 8 can release excess or over-pressure natural gas to ensure the safe operation of the system. The installation and operation of the entire equipment depends on a stable support frame. The frame includes a mounting base and a fixed bracket. The base is fixed on the ground. The fixed bracket is used to support and stabilize various pipelines and equipment to ensure the long-term stability and safety of the equipment.

[0022] To further improve the operational convenience and safety of the system, both turbine flowmeter 1 4 and turbine flowmeter 2 5 are equipped with data acquisition modules, which collect and transmit flow data to the remote monitoring system in real time. Through the integrated remote control device, the operator can not only monitor the operating status of the system, but also perform remote operation and adjustment to ensure the optimal operating status of the system under different pressure and flow requirements.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
