Abstract
The utility model relates to a backflow water attack prevention device for a branch pipe of a coal slurry pipeline, which can be applicable to preventing damage caused by water attack of the coal slurry pipeline. A power pump, a buffering tank, a pressure sensor, a flow meter, a backflow branch pipe and a ball valve are sequentially mounted on the coal slurry pipeline, wherein the backflow branch pipe consists of an inflow opening, a backflow pipe and an outflow opening; and when the ball valve is suddenly closed, the pressure of the water attack is increased, so that coal slurry enters the inflow opening, flows through the backflow pipe, and returns back to the coal slurry pipeline through the outflow opening. Therefore, the pressure of the water attack is reduced, and the coal slurry pipeline is protected.
Description
Affiliated technical field
The utility model relates to a kind of coal slurry pipeline arm backflow pressure surge proof device, can be widely used in the coal slurry conveyed in pipeline construction project, and the water impact preventing equipment use as coal slurry conveyed in pipeline belongs to coal slurry conveyed in pipeline water impact preventing equipment technical field.
Background technique
Before the utility model was made, the method for coal slurry conveyed in pipeline water impact preventing generally adopted safety valve or rupture disk to prevent water attack, but these methods are all that coal slurry is discharged into the outside, both wasted, polluted again environment, the time of replacing simultaneously is long, has affected the normal safe operation of coal slurry pipeline.
Summary of the invention
Break up bad problem in order to solve the coal slurry pipeline prevention of water, improve the method for existing coal slurry pipeline prevention water attack, improve science and the rationality of prevention water attack, guarantee the normal safe operation of coal slurry pipeline, the utility model provides a kind of coal slurry pipeline arm backflow pressure surge proof device, this coal slurry pipeline arm backflow pressure surge proof device is simple in structure, easy for installation, and the prevention water attack is effective.
The technological scheme that its technical problem that solves the utility model adopts is: it is that kinetic pump, knock out drum, pressure transducer, flowmeter, backflow arm and ball valve are installed on coal slurry pipeline successively; wherein reflux arm by entering head piece, reflow pipe and go out head piece to form; when ball valve is closed suddenly; surge pressure rises; coal slurry will enter into head piece, and the reflow pipe of flowing through is got back in coal slurry pipeline by going out head piece; thereby reduced surge pressure, protected coal slurry pipeline.
The beneficial effects of the utility model are, can be used for any coal slurry pipeline conveying engineering project, use as coal slurry pipeline prevention water attack equipment, and simple in structure, easy for installation, the prevention water attack is effective, has guaranteed the normal safe operation of coal slurry pipeline.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing is structural representation of the present utility model.
Above-mentioned number in the figure is described as follows:
1, coal slurry pipeline 2, kinetic pump 3, knock out drum 4, pressure transducer
5, flowmeter 6, backflow arm 7, ball valve 8, enter head piece
