TECHNICAL FIELD

[0002] A natural gas pipeline is a pipeline system used for transporting natural gas, usually composed of a series of connected pipelines, valves, pressure control devices, and related facilities, aiming to transport natural gas from production or storage sites to consumption sites.

[0003] The gas tightness detection of a natural gas pipeline is an important link to ensure the safety and effectiveness of the pipeline system.

[0013] Further, a fixed rod is rotationally connected in the detection box, a magnetic pole pointer and a direction pointer are fixedly connected with the two ends of the fixed rod respectively.

[0014] Further, the magnetic pole pointer is arranged between the two conductive spiral rods of the detection box, the direction pointer is arranged on the outer side of the detection box, and the outer side of the detection box is provided with scale lines arranged on the side of the direction pointer.

[0015] Further, the fixed sleeve is arranged at both ends of the adapter pipe, and the detection box is arranged on the outer side of the adapter pipe.

[0016] Compared with the prior art, the gas tightness detector for indoor gas pipeline has the following advantages:

[0017] 1. The transmission pipe is provided with a transmission shaft and a blade, and the gas flowing in the pipe will drive the blade to rotate around the transmission shaft, thereby driving the rotation of the bearing. The rotating bearing drives the rotation of the bent iron rod in the sleeve ring. The sleeve ring is provided with a magnetic block, so that the rotating bent iron rod cuts the magnetic field generated between the magnetic blocks. An induced current is generated by electromagnetic induction, and the induced current is transmitted to the transmission wire through the conductive end and the connecting end.

[0018] 2. When the induced current is transmitted to the current monitor, the indicator light can be turned on. By observing the display of the indicator light, the device can be self-checked during use. When the current flows in the current monitor, the current can be transmitted to the conductive spiral rod to generate an electromagnetic field. When the pipeline sealing is good, the current flowing in the two conductive spiral rods is equivalent, so the magnetic field generated will not affect the magnetic pole pointer. When the pipeline sealing has a problem, the size of the two magnetic fields will be different, thereby affecting the deflection of the magnetic pole pointer. By observing the direction and angle of deflection of the direction pointer on the outer side, it can be known which side of the pipeline has a problem and the degree of pipeline leakage.

[0019] 3. The volume of the assembly is reduced, only the detection function is retained, and the assembly can be directly installed beside the transmission pipe, thereby monitoring the sealing property of the pipeline at any time. DETAILED DESCRIPTION
