Abstract

The invention discloses a natural gas pipeline transportation gas leakage detection device, and relates to the technical field of natural gas pipeline transportation, the natural gas pipeline transportation gas leakage detection device comprises a main body mechanism, the main body mechanism comprises a main pipeline, the inner side of the main pipeline is provided with a detection mechanism, the left end of the main pipeline is provided with a connection mechanism, and the right end of the detection mechanism is provided with an alarm device. Natural gas flowing in the pipeline is detected through the detection plate, under the general condition, the detection plate is supported rightwards under the impact force of the natural gas, meanwhile, a movable block at the lower end of the detection plate is supported leftwards under the force of a first spring, the detection plate is kept balanced, and when gas leakage occurs in the pipeline, the stress of the detection plate is not stable any more; and then the stress of a pressure sensor at the left end of a first spring changes, an alarm is started, a first motor drives a first threaded rod to rotate, then a first sliding block moves upwards, and the first sliding block drives a vertical rod to move upwards till the vertical rod is clamped with the sealing box.

Description

technical field [0001] The invention relates to a gas leakage detection device, relates to the technical field of natural gas pipeline transportation, in particular to a gas leakage detection device for natural gas pipeline transportation. Background technique [0002] Natural gas refers to a kind of combustible gas existing in nature, which is a kind of fossil fuel, including gas formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcano gas, coal bed methane and biogas, etc.). The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. With the continuous improvement of urbanization in our country, the use of natural gas is gradually increasing. During the transportation process of natural gas, it is mainly transported through pipelines, and there w...
