A natural gas pipeline leak detection device

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, and specifically is a natural gas pipeline leak 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 treatment 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 more and more natural gas pipelines need to be installed. [0003] Some technical solutions for natural gas pipeline leakage detection devices have also appeared in the prior art. For example, a Chinese patent with an application number of 2017216119715 discloses a natural gas pipeline leakage detection device, including a shell, and the bottom of the inner wall of the shell is provided with The first sliding groove, ...
