Description
Technical field
The utility model belongs to a kind of tailrace, specifically, and the two automatic tailraces of float 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 water tank 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.
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: a kind of pair of automatic tailrace of float negative pressure, first buoyancy aid is housed in airtight water tank, this first buoyancy aid kink is on first guide peg, described airtight water tank top blind flange is provided with water intaking valve, push rod admission valve and magnet, described airtight water tank lower sidewall is provided with water check valve, the described first buoyancy aid end face is provided with sealing mat over against water intaking valve, its key is: described airtight water tank one side is equipped with the water tank that communicates with lower box, second buoyancy aid is housed in the described water tank, this second buoyancy aid is sleeved on second guide peg that is fixed in water tank bottom, have the negative-pressure balancing hole on the described water tank top board, the top board inner surface of this water tank is provided with magnet, and this magnet is positioned at second buoyancy aid top; The described second buoyancy aid top board is provided with sealing mat over against the negative-pressure balancing hole, and the top board of described first buoyancy aid and second buoyancy aid all is a steel plate.Described negative-pressure balancing hole is positioned at water tank top board central authorities, and the magnet that described water tank top board inner surface is provided with is symmetricly set on both sides, negative-pressure balancing hole.
Described negative-pressure balancing hole is positioned at water tank top board central authorities, and the magnet that described water tank top board inner surface is provided with is symmetricly set on both sides, negative-pressure balancing hole.
When tailrace when the extraction negative pressure line is all inserted by pipeline in water intaking valve and negative-pressure balancing hole under reset condition, first ball float and second ball float are all in the case bottom, the push rod air inlet valve position is in closed condition, water intaking valve is in free opening, because the effect of negative pressure, outlet valve is closed, beginning ponding in water tank and water tank when negative pressure line has water; Along with ponding increases, first, second ball float floats with the water surface, when first, second ball float rises to certain position, the preferential adhesive magnet of second ball float under the effect of water tank soffit magnet, the sealing mat that is fixed on above second ball float blocks the negative-pressure balancing hole, first ball float is the magnet on the adhesive cover plate after a while, clash into the valve rod of push rod admission valve and open admission valve, the sealing mat that is fixed on above first ball float is then closed water intaking valve simultaneously, cut off negative pressure and water inlet, ponding is opened out water one-way valve under action of gravity, beginning discharges water; When the gravity of second ball float that discharges water and buoyancy of water difference surpass the magnetic force of magnet on the water tank, second ball float falls suddenly, open the negative-pressure balancing hole and import negative pressure, after a while, when the gravity of first ball float and buoyancy of water difference surpassed the magnetic force of magnet on the cover plate, first ball float fell open water intaking valve suddenly, inlet valve spindle falls to closing admission valve, negative pressure raises in the case, and outlet valve is closed because of the effect of negative pressure, beginning ponding.And so forth, realize the ponding draining circulation of ponding again.
Beneficial effect: the utility model can guarantee that the action of admission valve and water intaking valve switches simultaneously, and water inlet one way valve and the reliable in action that goes out water one-way valve are switched; Not influenced by the pipeline vacuum magnitude, overall structure is simple, and is cheap, economical and practical, is convenient to promote.
