Embodiment

[0048] Such as figure 2 In the pressure regulating pipeline shown, the pressure setting values ​​of the inlet ball valve a, emergency shut-off valve b, working pressure regulator c, and outlet ball valve d in the running pressure regulating pipeline are shown in Table 2. The spare pressure regulating pipe The pressure settings of the inlet ball valve e, emergency cut-off valve f, working pressure regulator g, and outlet ball valve h in the road are shown in Table 2.

[0050]

[0051]

[0052] (a) The working pressure regulator c running the pressure regulating pipeline fails, and the outlet pressure of the working pressure regulator c rises. When the pressure rises to the pressure setting value of the emergency cut-off valve b running the pressure regulating pipeline 2.4MPa , cut off the emergency cut-off valve b of the operating pressure reg...

Abstract

The invention relates to a method and system for realizing automatic switching of natural gas pressure regulators. By reducing monitoring pressure regulators of pressure regulating pipelines and gradiently setting pressure values of working pressure regulators and emergency shut-off valves of an operation pressure regulating pipeline and a standby pressure regulating pipeline, when the pressure regulator of the operation pressure regulating pipeline breaks down and an emergency shut-off valve is shut off, automatic switching to the working pressure regulator of the standby pressure regulatingpipeline is conducted, and uninterrupted gas supply is ensured.

Description

technical field [0001] The invention belongs to the field of parameter setting of natural gas pressure regulators, and in particular relates to a method and system for realizing automatic switching of natural gas pressure regulators. Background technique [0002] Natural gas pressure regulator is the main core equipment such as natural gas gate station and pressure regulating station, and is an important link in the natural gas transmission and distribution pipeline network. Therefore, the normal and stable operation of the pressure regulator is a reliable guarantee for the safe operation of the natural gas pipeline network. It is especially important to be able to automatically switch to a backup regulator in the event of a regulator failure. [0003] Natural gas pressure regulator (hereinafter referred to as "pressure regulator") is the core equipment of natural gas gate station and pressure regulating station. The pressure is a certain constant value, which plays a conn...
