Abstract
The utility model relates to a gas concentration regulator comprising a shell, a first air shut-off device and a second air shut-off device which are connected in the shell by using flange connectors, a first regulating handle used for regulating opening/closing of the first air shut-off device, and a second regulating handle for regulating opening/closing of the second air shut-off device, wherein the second air shut-off device is provided with a locking device for prevention of free rotation; the regulator is used for regulating opening/closing states of the first air shut-off device through the first regulating handle and regulating the opening/closing states of the second air shut-off device through the second regulating handle, so that the requirement of not blowing the gathered high-concentration gas to the other part of an roadway is satisfied even if a blower is started immediately when the extraction work surface of a mine is suddenly powered off, or powered on or after the extraction work surface is powered on; the underground work environment of workers is further improved and the potential risk of the high-concentration gas in the roadway is eliminated.
Description
Technical field
The utility model relates to the mine operation of coalmine ventilation, the concrete adjusting device that relates to a kind of mine gas.
Background technology
When the coal mine operation, when the blowing-out of blower fan sudden power, the air channel air quantity reduces; Gas density increases, and back production or driving face gas density are very big, and incoming call back main air duct gas density is diluted with big air quantity; Easily the gas of high concentration is discharged to the another part in tunnel, so, the gas of high concentration is discharged to air return system if in the process of firedamp drainage, control bad distinguished and admirablely; Cause gas explosion easily, also occur personnel easily and poison or suffocation accident, make it have potential safety hazard.
Summary of the invention
For addressing the above problem, the utility model provides a kind of gas density adjuster, good reliability, and adjusting dilution gas density is easy, and security performance is good, and is easy to operate.
The technical scheme of the utility model is following: the gas density adjuster; Comprise housing, be connected in the disconnected wind device of first in the housing, the second disconnected wind device and be used for regulating first regulating handle of the first disconnected wind device keying, second regulating handle that the adjusting second disconnected wind device opens and closes that the said second disconnected wind device is provided with locking device through flange coupling connector.
The beneficial effect of the utility model is: through regulating handle, when turning clockwise, the air channel is closed; Otherwise the air channel is opened; Even incoming call back blower fan starts immediately when satisfying mine stope sudden power, incoming call, can the high concentration gas of assembling not blown to the another part in tunnel yet, further improved the working environment of operating personnel in the down-hole; To guarantee to eliminate the potential safety hazard of tunnel high concentration gas, make it meet safe mass standardization requirement.The second disconnected wind device is provided with locking device, in case arbitrarily rotate.
Description of drawings
Fig. 1 is the structural representation of the utility model gas density adjuster.
The specific embodiment
The gas density adjuster; Comprise housing 1, be connected in first disconnected wind device 4, the second disconnected wind device 5 in the housing 1 and be used for regulating the first disconnected wind device 4 opens and closes first regulating handle 2, regulate second regulating handle, 3, the said second disconnected wind device 5 that the second disconnected wind device 5 opens and closes and be provided with locking device 6 through flange coupling connector; During practical implementation; The gas density adjuster is connected an end of blower fan; Regulate the keying state that the first disconnected wind device 4, second regulating handle 3 are regulated the second disconnected wind device 5 through first regulating handle 2; Even to guarantee that incoming call back blower fan starts immediately, can the high concentration gas of assembling not blown to the another part in tunnel yet, eliminate the potential safety hazard of tunnel high concentration gas.
Claims (2)
1. the gas density adjuster is characterized in that comprising housing, is connected in the disconnected wind device of first in the housing, the second disconnected wind device and is used for regulating first regulating handle of the first disconnected wind device keying, second regulating handle that the adjusting second disconnected wind device opens and closes through flange coupling connector.
2. according to the said gas density adjuster of claim 1, it is characterized in that the said second disconnected wind device is provided with locking device.
