AI Technical Summary
Existing natural gas pipelines cannot automatically control the flow rate of distribution pipelines based on transmission pressure, and lack sealing detection devices, posing safety hazards.
A flow control device for natural gas distribution pipelines was designed, comprising a main pipeline, a short connecting pipe, a distribution pipe, a protective shell, and a regulating mechanism. The flow rate is regulated by a turntable and a spring, and a sealing ring and a detector are provided to prevent leakage.
It enables automatic flow adjustment based on delivery pressure, reducing the risk of leakage and improving safety and the accuracy of flow control.
