Technical Field
The invention relates to the field of coal mine air doors, in particular to an air door control valve convenient to adjust manually.
Background
Coal is a layer of extremely thick black humus which is formed by piling branches, leaves and roots of plants for millions of years on the ground, and is a black combustible sedimentary rock formed by continuously burying the coal underground due to the change of the crust, isolating the coal from the air for a long time, and carrying out a series of complex physical and chemical changes and other factors under high temperature and high pressure, which is the formation process of the coal. The thickness of the coal seam in a coal mine is related to the rate of descent of the crust and the amount of the remains of the plant in the area. The speed of the falling of the crustacean is high, the plant remains are stacked thickly, and the coal bed of the coal mine is thick, on the contrary, the speed of the falling of the crustacean is low, the plant remains are stacked thinly, and the coal bed of the coal mine is thin. The original horizontal coal seam is folded and broken due to the structural movement of the crust, some coal seams are buried in deeper places under the ground, and some coal seams are squeezed to the ground surface or even exposed out of the ground, so that the coal seam is easy to find by people. However, the exhausted gas is discharged into the atmosphere, and a strong greenhouse effect is generated, and the greenhouse effect of methane contained in the gas is 20 times greater than that of carbon dioxide. In addition, in the production process of coal mines, the underground roadway needs hundreds of thousands of air or even hundreds of thousands of cubic meters of air every second, and the underground roadway is mainly completed through mine ventilation which also contains gas and a large amount of dust.
