The utility model comprises a piston rod (12), a floating air cylinder (4), an upper cavity air port (21), a lower cavity air port (1), a vacuum release port (11), a liquid pumping channel (20), a liquid draining channel (19), an upper guide sleeve (6), a middle guide sleeve (9), a lower guide sleeve (13), a plunger (16), etc. The utility model is a two-location three-way action valve of the single floating cylinder type horizontal sealing face, and has the advantages of simple structure, reliable program behavior, etc.; one valve can serve two purposes.
Description
The utility model is a kind ofly to carry out gas-liquid separation and the outside chemical industry special arrangement used of the vacuum balancing liquid-discharge of discharge liquid automatically for the crawler type filter synchronously when liquid-solid separation.This device needs with the floating supporting application of cylinder cylinder control valve.
The liquid-solid separation field of chemical industry often adopts vacuum suction filter (suction filtration) method.All tie up to and use filter medium under the normal pressure, through the promotion of pressure differential, make the liquid permeates medium and flow to the one side of vacuum, solid matter is filtered medium and holds back and separate.But, filter medium can not be very fine and close, through vacuum suction filter, the two-phase of gas-liquid often of extracting out, just need utilize vacuum that gas is extracted once more and carry out gas-liquid separation, just must will be contained in the liquid that is separated in the separator, infuse again or discharge opeing after gas in the liquid is discharged.This has relatively high expectations to the pump vacuum capability, often need to close or open vacuum port and leakage fluid dram mechanism respectively with two groups of keg floats, and keg float need carry out on-the-spot counterweight according to the difference of vacuum.This separation method makes the equipment complex structure, complex operation, and maintenance difficult involves great expense.
The utility model will provide a kind of buoyancy-driven mechanism that utilizes, and carry out gas-liquid separation in a container continuously, not need vacuum pump divided gas flow from liquid, again can be automatically the outside isolated plant of discharge liquid.
Technical essential of the present utility model is the cylindrical shell that a branch is made epicoele (12) and cavity of resorption (18), the center is provided with by ball float chamber (19), ball float (21), control device and left side inner liquid port (15) that valve lever (6) is formed, the vacuum balancing liquid-discharge device that pumping equipment constituted that the exterior liquid mouth (23) of lower end is formed.Its control device is controlled with the end that connecting rod (16) connects valve lever (6) by the ball float (21) in ball float chamber (19).Valve lever (6) is contained in to hand over and makes it movable on the bearing (4), the inboard appropriate location of valve lever (6) is equipped with one and is controlled interior the valve rod (24) that air inlet (2) is gone up valve plug (1) upward, and vacuum port (25) outer the valve rod (25) of valve plug (7) down is equipped with in the control on valve lever (6) top downwards.Movable lower cover (22) also is equipped with in the outside that movable upper cover plate (14) and exterior liquid mouth (23) are housed at inner liquid port (15).
Fig. 1 is the structure sketch map of vacuum balancing liquid-discharge device.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
At a housing that is divided into epicoele (12) and cavity of resorption (18), take back a little columnar top clamshell (3) be housed in the top, and air inlet (2) is equipped with at top clamshell (3) top.The outer vacuum port (8) that connects with vacuum source is housed in the case top side of taking over, the housing upper left-hand is equipped with a liquid pumping hole (10) that connects with the band filter filter disc, an epicoele scale (13) and cavity of resorption scale (20) for the indication liquid level position respectively is equipped with on the housing right side, left side, housing middle part is one the inner liquid port (15) of upper cover plate (14) and the side clamshell (11) of cavity of resorption through hole (17) is housed that the exterior liquid mouth (23) of lower cover (22) is equipped with in the housing bottom left side.During being separated, enclosure interior becomes epicoele (12) and cavity of resorption (18).A ball float chamber (19) is equipped with in the centre of housing, and separate with the housing inner bottom part bottom, ball float chamber (19), and separation distance is about 1/8 of housing height, and a ball float (21) that connects with the same valve lever of connecting rod (16) (6) is arranged in ball float chamber (19).Valve lever (6) is installed in top shell (3) inside, and the same ball float of one end (21) connecting rod (16) connects.Valve lever (6) in the top clamshell (3) is installed in to be handed on the bearing (4).Hand over the nearly centre of valve lever (6) between the same connecting rod of bearing (4) (16) by in upward
Valve rod (24) will be gone up valve plug (1) opens and closes air inlet (2).Hand over bearing (4) outer valves lever (6) to have one outer valve rod (5) will descend valve plug (7) that interior vacuum port (25) is opened and closed downwards.
During work, outer vacuum port (8) is connected vacuum source, begin to vacuumize, ball float (21) falls, affect the connecting rod (16) in the ball float chamber (19) to drive valve lever (6), will go up valve plug (1) and air inlet (2) be closed with the following valve plug (7) of interior vacuum port (25) open.Epicoele (12) and cavity of resorption (18) are linked up by ball float chamber (19), form vacuum simultaneously, this time exterior liquid mouth (23) lower cover (22) held and closed.When epicoele (12) and cavity of resorption (18) reach same vacuum and when realizing the vacuum balance, the upper cover plate (14) of inner liquid port (15) is in free state.Gas-liquid mixture is tangential direction from liquid pumping hole (10) and enters cylindrical shell epicoele (12), liquid is contained in the epicoele (12), the liquid nationality fluid pressure of divided gas flow is pushed inner liquid port (15) upper cover plate (14) open in epicoele (12), flows into cavity of resorption (18) in a steady stream through through hole (17) and also stockpiles gradually.Cavity of resorption (18) liquid level increases and soaks and ball float (21), increase to until buoyancy and to overcome pull of vacuum, ball float (21) floats, promote connecting rod (16) and affect valve lever (6), the last valve plug (1) of air inlet (2) is opened with the following valve plug (7) of interior vacuum port (25) closed, air enters and makes the forfeiture of cavity of resorption (18) vacuum.This time close because of interior vacuum port (25), so the forfeiture as yet of epicoele (12) vacuum.Epicoele (12) and cavity of resorption (18) vacuum be balance no longer, and the upper cover plate (14) that epicoele (12) pull of vacuum will inner liquid port (15) holds and closes.At this moment, epicoele (12) still keeps and carries out drawing liquid and gas-liquid separation.In the still temporary epicoele (12) of liquid after the separation.When atmosphere enters cavity of resorption (18) when reaching balance with the outer atmospheric pressure of tube continually, because the gravity of Sheng liquid is opened exterior liquid mouth (23) lower cover (22) gradually, liquid just outwards discharges until big portion and is drained.This time ball float (21) deadweight overcome pull of vacuum and fall.Affect valve lever (6) that the following valve plug (7) of interior vacuum port (25) is opened by connecting rod (16), the last valve plug (1) of air inlet (2) is closed, begin again cavity of resorption (18) is vacuumized, the lower cover (22) of exterior liquid mouth (23) is closed again automatically, subsequently, epicoele (12) the liquid of dissipation gas enter cavity of resorption (18) again.Carry out work so again and again, reach the purpose that solution-air is separated.
