Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure regulators, in particular to an intelligent pressure regulator for a gas pipeline. Background Art

[0002] As we all know, as the consumption of natural gas in my country continues to maintain a high-speed growth, the safety of natural gas pipelines has become increasingly prominent, and higher requirements have been put forward for the safe operation and management of the natural gas system. Among them, the gas pressure regulator is one of the common and important pressure regulating facilities. Whether it can operate normally and stably is directly related to the stability and safety of gas use by downstream users. The gas pressure regulator, commonly known as the pressure reducing valve, is actually a special valve. As an indispensable pressure regulating device in the gas pipeline network, it automatically changes the gas flow rate of the gas to reduce pressure and maintain the stability of downstream pressure.

[0003] Existing intelligent pressure regulators for gas pipelines are provided with an exhaust pipe, which can release the gas when the internal pressure is too high to ensure the safety of the equipment. If the exhaust pipe is blocked, it will be very dangerous, so a protective net is usually installed at the end of the exhaust pipe.

[0004] When the staff inspects and maintains the gas pipeline with the intelligent pressure regulator, they also need to clean the protective net at the exhaust pipe (dust, gravel, broken leaves, weeds, spider webs, etc. on the protective net). The staff needs to carry cleaning tools with them, and when using them, they need to take the cleaning tools out of the tool box to clean the protective net, which is inconvenient.
