AI Technical Summary
Existing natural gas pipeline leak detection equipment is difficult to accurately detect leaks at pipeline connections, and is easily affected by distance and wind factors, resulting in unsatisfactory detection accuracy.
An adjustable natural gas pipeline leak detection device was designed, including a branch pipe, an arc pipe, a suction nozzle, a flexible pipe, a swivel branch assembly, and a relative swivel drive adjustment assembly. Through the cooperation of these components, the natural gas pipeline connection can be surrounded at close range, and accurate detection can be performed using an air pump and a natural gas leak detection alarm.
It enables precise close-range detection of natural gas pipeline connections, avoiding the impact of distance and wind factors, and improving the accuracy and applicability of the detection.
