Description

Technical Field

[0001] The invention relates to the technical field of gas pressure regulation, in particular to an intelligent pressure regulating box for a gas pressure regulator. Background Art

[0002] At present, the operation and management of gas pressure regulating stations are mainly achieved through daily inspections, relying on the experience of managers to judge whether the gas pressure regulator has a fault; however, this traditional, manual judgment method has many problems.

[0003] (1) There is no unified standard for determining the faulty and normal states of gas pressure regulators: Relying solely on the technicians’ experience to troubleshoot faults will result in many uncertainties. For example, for the same situation, some technicians believe it is a normal state, while others believe it is a faulty state, thus posing a potential safety hazard to the gas pressure regulator.

[0004] (2) Minor abnormal conditions of gas pressure regulators are difficult to detect: In the actual operation of gas pressure regulators, some parts will be damaged after working for a period of time, but minor abnormal conditions are often difficult to be discovered by management personnel, especially for gas pressure regulators in the ring network, where pressure and flow complement each other, and it is impossible to judge abnormal conditions based on a single variable. If the entire pressure regulation process deviates from the normal state for a long time, the failure of the gas pressure regulator will become increasingly worse, and when the aggravated abnormal conditions are discovered, more maintenance costs will be added.

[0005] (3) Serious waste of human and financial resources: To ensure the safe operation of the gas pressure regulator, the existing method is to formulate a set of strict maintenance and repair operation procedures and require personnel at all levels to strictly implement them. However, this conservative operation and management system greatly increases the production and operation costs. Summary of the invention
