Air booster

Abstract

The invention discloses an air guiding and boosting device, which comprises a cylinder body, a piston assembly arranged inside the cylinder body, and a drive assembly for driving the piston assembly to move longitudinally along the cylinder body. The air guide channel is provided with a one-way valve that can only be opened in one direction along the air intake direction; the front end of the cylinder is provided with an air intake channel, and an exhaust valve that communicates with the air guide channel and is connected with the gas detection device is also provided. aisle. When the device is in a negative pressure state, it does not need to overcome the atmospheric pressure to perform work when taking gas from the gas drainage pipeline, thereby improving the gas taking efficiency.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to an air guiding booster device. Background technique [0002] In the process of coal mining, the determination of gas drainage pipeline parameters has always been the prerequisite for safe mining of gas mines. How to accurately and efficiently measure the parameters of gas drainage pipelines is one of the key issues that need to be solved urgently in my country's coal mine safety mining. At present, most of the parameters of the gas drainage pipeline are measured by using the pump to extract the gas from the pipeline, enter the measuring instrument for measurement, and then empty it. The gas pump needs to overcome the atmospheric pressure in the process of taking gas from the gas drainage pipeline in a negative pressure state. To do work, especially on the gas drainage pipeline with a large negative pressure, it is time-consuming and labor-intensive to get gas from the pump, a...

Problems solved by technology

At present, most of the parameters of the gas drainage pipeline are measured by using the pump to extract the gas from the pipeline, enter the measuring instrument for measurement, and then empty it. The gas pump needs to overcome the atmospheric pressure in the process of taking gas from the gas drainage pipeline in a negative pressure state. To do work, especially on the gas drainage pipeline with a large negative pressure, it is time-consuming and labor-intensive to get gas from the pump, and the efficiency is low. What is more important is that during the measurement process, due to the influence of the air in the pipeline itself, the measurement of parameters such as gas concentration is not accurate. precise
