Embodiment approach

[0022] As an embodiment of the present invention, a guide hole 18 is provided in the guide block 17, and the spring wire of the spring 14 is designed to pass through the guide hole 18; during work, because the spring wire of the spring 14 passes through the guide hole 18 design, the effective Prevent the spring 14 from twisting when it rotates, causing the guide block 17 to lose its teeth and affect the operation of the device. At the same time, it plays a good fixing role to prevent the spring 14 from swinging when rotating, so that the first slider 22 swings, making the device run more smoothly.

[0023] As an embodiment of the present invention, the inner wall of the guide hole 18 is designed with a graphite edge; during operation, the graphite edge plays a good lubricating effect, reduces friction and generates heat at the same time, prevents natural gas from burning due to excessive heat, and the spring 14 rotates Graphite can smear the spring wire surface of spring 14 eve...

Abstract

The invention belongs to the technical field of natural gas pipeline equipment, and in particular relates to a natural gas pipeline leakage detecting device. The natural gas pipeline leakage detectingdevice comprises a frame body and a controller. A first slide plate and a second slide plate are both circularly designed and slidably connected to the inner wall of the frame body, and the first slide plate is located below the second slide plate. A spring is fixed between the lower surface of the first sliding plate and a rotating shaft of a motor. A moving plate is U-shaped, and the moving plate is connected to the fixing ring through a bearing. A sliding slot is formed in a lower surface of the second sliding plate; and two sliding blocks are slid in the sliding slot. The sliding blocks are initially located at two ends of the sliding slot, and a first swinging lever is connected between a left sliding block and a right side gear, and a second swinging rod is connected between the right side sliding block and a left side gear. A guide hole is defined in each guide block, and spring wires of springs are designed to pass through the guide holes. Bellows is fixedly connected betweenan alarm and the inner wall of a fixed barrel, and the bellows is in communication with a cylinder. The natural gas pipeline leakage detecting device has the advantages of simple and convenient operation and long detection distance.

Description

technical field [0001] The invention belongs to the technical field of natural gas pipeline equipment, in particular to a natural gas pipeline leakage detection device. Background technique [0002] Natural gas pipeline refers to the pipeline that transports natural gas, including associated gas produced in oil fields, from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. With the continuous improvement of people's living standards, natural gas The use has also entered every household, and there are more and more natural gas pipelines that need to be installed. [0003] There are also some technical solutions for natural gas pipeline leakage detection devices in the prior art. For example, a Chinese patent with application number 2017216119715 discloses a natural gas pipeline leakage detection device, which includes a shell, and the bottom of the inner wall of the shell is opened with a The firs...
