Description

Technical Field

[0001] The utility model relates to the technical field of natural gas equipment, in particular to a pressure regulating device. Background Art

[0002] Natural gas valves are key equipment in the process of natural gas transportation and use. They have important functions such as controlling gas flow, preventing backflow, and isolating fault sections. The types and performance of natural gas valves are also constantly improving, providing a strong guarantee for the safe and efficient transportation and use of natural gas. Natural gas valves are widely used in natural gas pipelines, gas storage, gas power generation, urban gas and other fields. In natural gas pipelines, valves are used to control the flow direction and flow of gas to ensure the safe operation of the pipeline. In gas storage, valves are used to store and regulate gas. In the field of gas power generation, valves play a role in regulating gas pressure and flow to ensure the stable operation of the generator set.

[0003] In addition, when natural gas is transported, the transportation pressure of the natural gas is usually adjusted accordingly. Natural gas pressure regulation is an important process. Its purpose is to adjust high-pressure natural gas to low-pressure natural gas suitable for use. This process usually involves a series of complex equipment and systems, including pressure regulators, pipelines, valves, sensors, etc. The use of natural gas valve regulation mainly refers to controlling the flow and pressure of natural gas through specific equipment or methods to meet different usage requirements. Most of the existing pressure regulating devices use electronic control, which is complicated to maintain when a failure occurs. Therefore, it is necessary to design a new pressure regulating device.
