Abstract
The utility model discloses an automatic drainage device of an underground pressure ventilation pipe. The automatic drainage device comprises a U-type steel tube in serial connection with the pressure ventilation pipe, an air guide steel tube is in parallel connection with the middle of the U-type steel tube, the bottom of the U-type steel tube is provided with a water drain valve, and an overflow valve is arranged on a position, below a horizontal plane of the air guide steel tube, of the vertical portion of the U-type steel tube. The automatic drainage device achieves automatic drainage of accumulated water in the pressure ventilation pipe, reduces bad influences of the accumulated water in the pressure ventilation pipe on pneumatic equipment, and has the advantages of being simple, practical, convenient to install and maintain, low in operation cost and the like.
Description
Technical field
The utility model relates to air line under the coal mine.
Background technology
Under the coal mine in the compressed-air system because to press the wind conveyance conduit be closed, can't discharge water midway, cause compressed air to arrive behind the getting working face with a certain amount of ponding, affect pneumatic equipment and works.Simultaneously, because a part of ponding exists in the airduct and can't get rid of, increase pipe and decreased, reduced the conveying capacity of airduct.
Summary of the invention
For overcoming the above problems, the utility model designs a kind of down-hole air line automatic water draining device, by this device the ponding in the airduct is emitted, thereby reduces ponding to the impact of pneumatic equipment and the carrying capacity of a pipeline.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of down-hole air line automatic water draining device, it is characterized in that, it comprises a U-shaped steel pipe that is serially connected in the air line, the middle part of U-shaped steel pipe air guide steel pipe in parallel, bottom at U-shaped steel pipe is equipped with discharging valve, at the vertical position of U-shaped steel pipe and the position that is in below the air guide steel pipe horizontal plane spilling water valve is installed.
Operating principle is: under the normal operating conditions, the discharging valve in the steam trap connection is closed condition, and the spilling water valve is the temporary close state, when pressing wind through out-of-date, is circulated downwards by the air guide steel pipe, and the condensation ponding in the airduct then is accumulated in the U-shaped steel pipe.When water level reaches spilling water valve horizontal plane position, open the spilling water valve, automatically discharge pressing under the wind action, by adjust spilling water valve discharge rate make it with the ponding velocity balance after, the spilling water valve can be in normally open; Namely prevent from too leaking out and ponding is in time discharged this moment.After the regular period, open discharging valve, remove the silt thing in the U-shaped steel pipe.
This device has been realized the automatic-discharging of ponding in the air line, has reduced in the air line ponding to the harmful effect of pneumatic equipment; Have the advantages such as simple and practical, that installation and maintenance convenient, and running cost is low.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data, 1-air line, 2-U shape steel tube, 3-air guide steel pipe, 4-discharging valve, 5-spilling water valve.
The specific embodiment
As shown in Figure 1, a kind of down-hole air line automatic water draining device, it comprises a U-shaped steel pipe 2 that is serially connected in the air line 1, the middle part of U-shaped steel pipe 2 air guide steel pipe 3 in parallel, in the bottom of U-shaped steel pipe 2 discharging valve 4 is installed, at U-shaped steel pipe 2 vertical positions and the position that is in below air guide steel pipe 3 horizontal planes spilling water valve 5 is installed.
