Abstract
The utility model belongs to mining equipment technical field, is specifically related to the two butterfly valve air door of a kind of coal mine ground main fan.The utility model mainly solves the main fan that existing air door exists and does not shut down the technical problem that cannot fix a breakdown when breaking down in running.The technical solution adopted in the utility model is: the two butterfly valve air door of a kind of coal mine ground main fan, comprises tunnel joint, the first butterfly valve and the first air duct, wherein: it also comprises the second butterfly valve and the second air duct.The utility model has to break down at not blowing-out state lower wind door easily to be got rid of and expense is low, quick for installation and without the need to the advantage of civil engineering.
Description
Technical field
The utility model belongs to mining equipment technical field, is specifically related to the two butterfly valve air door of a kind of coal mine ground main fan.
Background technology
Coal mine main fan has important function to Safety of Coal Mine Production, which is responsible to delivered downhole fresh air, discharges the critical function of dirty wind and dust, guarantee safety in production.Country's safety regulations in coal mine requires each mine main ventilator the using and the reserved.Conveniently two Fans run and switch, and all install dissimilar air door and do airtight switching and use between every Fans and wind cave.Present air door is all only installed a butterfly valve to do airtight switching, therefore, when its air door existed breaks down in running, must stop the technical problem that main fan just can be fixed a breakdown.
Summary of the invention
Do not shut down the technical problem that cannot fix a breakdown when the purpose of this utility model is breaking down in running of the existing air door existence of solution, provide a kind of coal mine ground main fan two butterfly valve air door.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The two butterfly valve air door of a kind of coal mine ground main fan, comprise tunnel joint, the first butterfly valve and the first air duct, wherein: it also comprises the second butterfly valve and the second air duct, one end of described tunnel joint is connected with one end of the first air duct, the other end of the first air duct is connected with the second air duct, and the first butterfly valve is located in the first air duct; The other end of the second air duct is connected with the air outlet of blower fan, and the second butterfly valve is located in the second air duct, and the other end of tunnel joint is connected with the air intake of ventilating duct.
Described first butterfly valve and the second butterfly valve are manual, electric dual-purpose butterfly valve.
The utility model adopts above technical scheme; two butterfly valves are set between ventilating duct and main fan; first butterfly valve is service valve; second butterfly valve is standby valve; when the first butterfly valve breaks down; close the second butterfly valve, get rid of the fault of the first butterfly valve, solve existing air door exist break down in running time do not shut down the technical problem that cannot fix a breakdown.Therefore, compared with background technology, the utility model has to break down at not blowing-out state lower wind door easily to be got rid of and expense is low, quick for installation and without the need to the advantage of civil engineering.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention
As shown in drawings, the two butterfly valve air door of a kind of coal mine ground main fan in the present embodiment, comprise tunnel joint 1, first butterfly valve 2 and the first air duct 3, wherein: it also comprises the second butterfly valve 5 and the second air duct 4, one end of described tunnel joint 1 is connected with one end of the first air duct 3, the other end of the first air duct 3 is connected with the second air duct 4, and the first butterfly valve 2 is located in the first air duct 3; The other end of the second air duct 4 is connected with the air outlet of blower fan 6, and the second butterfly valve 5 is located in the second air duct 4, and the other end of tunnel joint 1 is connected with the air intake of ventilating duct 7.
Above-mentioned first butterfly valve 2 and the second butterfly valve 5 are manual, electric dual-purpose butterfly valve.
