Abstract
A kind of gas pumping automatic water drainage device, suitable for excluding the ponding methane gas extraction pipeline.It is made of gas pumping pipe, connecting tube and U-tube.One connecting tube is installed in gas pumping pipe lowest point, is equipped with valve by flanged joint, the lower end of connecting tube between connecting tube and gas pumping pipe and is connected a U-tube, there are one airtight stopper, height of the airtight stopper apart from gas pumping pipe is the installation of U-tube endWherein P is peak suction in extraction pipeline, and ρ is the density of water.Valve closes, stoppers airtight stopper when installing gas pumping automatic water drainage device, and U-tube mouth is placed in water tank after installation is complete, airtight stopper is pulled out and opens valve, removes water tank after water column in U-tube no longer rises.The invention is easy to operate, performance is stable, high safety, has wide applicability.
Description
Technical field
The utility model is related to a kind of gas pumping technical fields, are taken out for gas more particularly, to a kind of underground coal mine
Adopt automatic water drainage device.
Background technology
Since the pressure in methane gas extraction pipeline is in negative pressure state, the moisture in coal seam pumping can be extracted into mash gas extraction
It adopts and forms ponding in pipeline, to reduce the accommodating space of gas in extraction pipeline, therefore, it is necessary to periodically discharge extraction pipeline
In ponding.The prior art is that multiple discharge outlet are opened up on methane gas extraction pipeline, and discharge outlet is equipped with discharging valve, side manually
Method is periodically drained, and this method belongs to interval and discharges water, time-consuming and laborious, seriously affects gas pumping effect.
Invention content
Technical problem：The purpose of the utility model is to overcome shortcomings present in prior art, provide a kind of method
Simply, gas pumping automatic water drainage device that is safe, continuously discharging water.
Technical solution：To realize the above-mentioned technical purpose, the utility model be used for gas pumping automatic water drainage device, including watt
Valve in funnelform connecting tube lower end is arranged in this drainage tube, funnelform connecting tube, is equipped with below funnelform connecting tube
U-tube, U-tube both ends one end are connected with funnelform connecting tube, valve setting funnelform connecting tube and U-tube it
Between, the U-tube other end is equipped with airtight stopper, and height of the airtight stopper apart from gas pumping pipe isP is in extraction pipeline in formula
Peak suction, ρ are the density of water, and g is acceleration of gravity.It is first shut off valve when gas pumping automatic water drainage device is installed, stoppers
Nozzle at U-tube airtight stopper is placed in water tank by airtight stopper after installation is complete, is pulled out airtight stopper and is opened valve, waits for U-tube
Middle water column removes water tank after no longer rising.Funnelform connecting tube is by flanged joint on gas pumping pipe.Connecting tube lower end
It is the collection that funnel-form is convenient for ponding in extraction pipeline.
Advantageous effect：Ponding can be made to enter the leakage of automatic water drainage device along funnel in gas pumping pipe there are when ponding
In bucket-shaped connecting tube, ponding is discharged in time automatically from U-tube end, discharge ponding can be realized using valve, is not necessarily to people
Work detaching pipelines are cleaned, and reduce in gas pumping pipe and water blockoff problem occur, and drainage effect number is simple in structure, easy to operate, tool
There is wide applicability.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram for gas pumping automatic water drainage device of the present invention.
In figure：1- gas pumping pipes, 2- connecting tubes, 3- valves, 4-U type pipes, 5- airtight stoppers, 6- flanges.
Specific implementation mode
Embodiments herein is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model is used for gas pumping automatic water drainage device, it includes gas pumping pipe 1, funnel-form
Connecting tube 2, valve 3 and water tank in 2 lower end of funnelform connecting tube are set, funnelform connecting tube 2 is connected by flange 6
On gas pumping pipe 1, connecting tube lower end is that funnel-form is convenient for collecting ponding in extraction pipeline, 2 lower section of funnelform connecting tube
Equipped with U-tube 4,4 both ends one end of U-tube is connected with funnelform connecting tube 2, valve 3 setting funnelform connecting tube 2 with
Between U-tube 4,4 other end of U-tube is equipped with airtight stopper 5, and height of the airtight stopper 5 apart from gas pumping pipe isP is in formula
Peak suction in extraction pipeline, ρ are the density of water, and g is acceleration of gravity.It is closed first when gas pumping automatic water drainage device is installed
Valve closing door 3 stoppers airtight stopper 5, and the nozzle at U-tube airtight stopper 5 is placed in water tank after installation is complete, pulls out airtight stopper 3 simultaneously
Valve 3 is opened, removes water tank after water column in U-tube 4 no longer rises.
