Description
Technical field
The utility model belongs to a kind of tailrace, specifically, and the automatic tailrace of negative pressure line in a kind of gas discharge in mine system.
Background technology
At present, the automatic tailrace of negative pressure line that domestic vast coal mining enterprise uses in the gas discharge in mine system, mostly be to adopt the floatage-type structure, promptly when the ball float in the tailrace ponding bucket with the water surface up and down and up and down the time, link by the water intaking valve of tailrace and the switching mechanism and the ball float of draining valve, thereby realize the function that tailrace discharges water automatically.But, because the automatic tailrace of negative pressure line of people's design in the past, majority is designed to the vertical inlet mouth, ball float come-up is just closed water inlet and is discharged water, and when ball float gravity during greater than negative-pressure sucking and magnetic force sum, ball float is thrown off water inlet, but because of water inlet bigger, negative pressure hour can normally be used, and suction is big when negative pressure is big, and buoyancy aid is not easy to separate just malfunctioning with the negative-pressure balancing valve; In order to overcome the influence of vacuum magnitude, what have establishes horizontal water inlet, and on water inlet one way valve valve plate, stay the pressure release of negative-pressure balancing hole, but gas drainage system often needs many tailraces to use simultaneously, and the negative-pressure balancing hole discharges water in assurance and makes the loss of pipe-line system negative pressure bigger reliably simultaneously, causes whole extraction system effectiveness to descend, energy consumption strengthens, less economical, and when the extraction pipeline laying is low, just can't discharge water, its service condition is seriously limited.Tailrace described in the utility model can reliably discharge water, and is not subjected to the restriction of vacuum magnitude and installation site simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of pipeline vacuum magnitude that is not subjected to influence the automatic tailrace that limits with the installation site.
The technical solution of the utility model is as follows: the automatic tailrace of a kind of negative pressure line, in airtight ponding bucket, buoyancy aid is housed, this buoyancy aid is sleeved on the guide peg that is fixed in airtight ponding bucket bottom, described airtight ponding bucket lower sidewall is provided with water check valve, its key is: described airtight ponding bucket side wall upper part is provided with unidirectional water intaking valve, these airtight ponding bucket top blind flange central authorities are provided with threeway negative-pressure balancing valve, described negative-pressure balancing valve side interface is communicated with through branched pipe with the water intake valve side, the cover plate of these negative-pressure balancing valve both sides is provided with the push rod admission valve, described cover plate soffit is fixed with magnet, and described buoyancy aid end face is provided with sealing mat, iron block, push rod respectively with cover plate on the negative-pressure balancing valve, push rod admission valve and magnet are corresponding one by one.The top sub of described negative-pressure balancing valve communicates with negative pressure line in the gas discharge in mine system by pipe, and the below communicates with the ponding bucket, and sidewall is communicated with water inlet one way valve influent side and negative-pressure balancing valve with conduit.When not needing low level to discharge water, water intaking valve negative-pressure balancing valve upper end can be blocked with plug, structure changes also to some extent can reach same purpose.
Other has a kind of scheme, the automatic tailrace of a kind of negative pressure line, in airtight ponding bucket, buoyancy aid is housed, this buoyancy aid is sleeved on the guide peg that is fixed in airtight ponding bucket bottom, described airtight ponding bucket lower sidewall is provided with water check valve, its key is: described airtight ponding bucket side wall upper part is provided with unidirectional water intaking valve, these airtight ponding bucket top blind flange central authorities are provided with the negative-pressure balancing valve, the cover plate of these negative-pressure balancing valve both sides is provided with the push rod admission valve, described cover plate soffit is fixed with magnet, and described buoyancy aid end face is provided with sealing mat, iron block, push rod respectively with cover plate on the negative-pressure balancing valve, push rod admission valve and magnet are corresponding one by one.Water intaking valve and negative-pressure balancing valve all communicate with negative pressure line in the gas discharge in mine system by pipe.The place that is different from aforementioned schemes is, these airtight ponding bucket top blind flange central authorities are provided with two logical negative structures and press equalizing valves, its top sub communicates with negative pressure line in the gas discharge in mine system by pipe, the below communicates with the ponding bucket, and the influent side of inlet pipeline and negative-pressure balancing valve top all communicate with negative pressure line in the gas discharge in mine system by pipe.
More than two kinds of scheme negative-pressure balancing valves smaller with the aperture that airtight ponding bucket communicates, the suction that produces is also very little, can't surpass the poor of the gravity of ball float and buoyancy, so it is opened accurately and reliably, the pressure reduction that also just can guarantee water inlet one way valve both sides disappears immediately, guarantee the normal unlatching of water intaking valve, water inlet one way valve and go out that water one-way valve switches accurately, switch is reliable.The accuracy of switching between them is that the order of leaning on the one way valve place to produce negative pressure realizes, and when water inlet one way valve influent side is in negative pressure, the outlet valve place should be normal pressure, when the outlet valve place is negative pressure, water inlet one way valve place does not have pressure reduction, and this switching is by the fluctuating of ball float, and under the effect of magnet and gravity, the switching of admission valve and negative-pressure balancing valve is all finished in moment
Thereby it is accurate to realize that negative pressure is switched.
When negative pressure line paving location in the gas discharge in mine system is low, can be by two even many s' tailrace series connection, one discharging valve is communicated with another water intaking valve.Pipeline ponding is emitted from the low-lying higher position that is pumped to, realize that low level discharges water.Its principle is exactly that outlet valve with the low level tailrace is communicated with the water intaking valve of the tailrace of higher position, introduce negative pressure by the negative-pressure balancing valve from negative pressure line, guarantee that there is negative pressure at high-order tailrace water intaking valve place, make the same operate as normal of high-order tailrace with the low level tailrace, different is that when the unlatching of low level tailrace outlet valve discharged water, the water of emitting was aspirated by the negative pressure at high-order tailrace water intaking valve place, become the water inlet of high-order tailrace, realize the purpose of ponding to high bit transition; Certainly, the suction height is decided by the vacuum magnitude in the pipeline, and adopts how many platform tailrace interlocks, then needs to calculate with the height and the pipeline vacuum magnitude of draining.
Beneficial effect: the utility model water inlet one way valve is reliable with the switching that goes out water one-way valve, and admission valve and negative-pressure balancing valve switch simultaneously; Not influenced and pipeline mounting condition restriction (many tailraces are together in series and can realize that low level discharges water) by the pipeline vacuum magnitude, satisfactory for result and simple in structure, economical and practical; Reduced the volume of ponding bucket in addition.
