Summary of the invention

The technical problem to be solved in the present invention provides a kind of density difference automated fluid escape cock, can discharge a certain liquid in two kinds of mixing materials automatically singlely.

In order to address the above problem, the invention provides a kind of density difference automated fluid escape cock comprises: proportion between two kinds of mixing materials ball float, have shell, leverage and the valve port of mixing material inlet opening and single liquid exhaust port, on the valve port installation exhaust port position in the enclosure, described ball float is controlled described valve port unlatching and closed by described leverage.

Preferably, described valve port comprises valve seat and valve rod, is symmetrically arranged with the first suitable inlet of section area and second inlet on the valve seat up and down, and valve rod is provided with described first inlet of control and second enter the mouth first spool and second spool of while closure or openness.

Preferably, the face that matches with described first and second inlet of described first and second spool is taper shape or elliposoidal.

Preferably, also be provided with the grinding faying surface that distributes along circumferentially on described first and second spool and the face that described first and second inlet matches.

The present invention has following advantage:

1, utilize the density difference of different liquids, the valve port of the floating ball lever mechanism controls discharge liquid that the employing Archimedes' principle is designed can compare the control of accurate discharging and liquid level to a certain liquid in the metastable mixing material of layering;

2, the electric autocontrol equipment that need not to increase input, it is on duty to need not personnel's execute-in-place;

3, utilize mutually the difference force equal and opposite in direction of the bivalve mouth that top, area are equated but direction is opposite, to make a concerted effort be zero principle, realize effectively the opening or closing of liquid emission valve under the ultra micro buoyancy condition.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is for being provided with the structural representation that grinds faying surface on spool.

Embodiment

Cooperating Fig. 1 to the specific embodiment of the present invention below, is that example is described in further detail with the oil-water mixture body.

As shown in Figure 1, the present invention includes: proportion is ball float 2, the shell 1 with oil-water mixture body inlet opening 5 and oily single liquid exhaust port 6, leverage 3 and valve port 4 between oil and two kinds of mixing materials of water, valve port 4 is installed on exhaust port 6 positions in the shell 1, and ball float 2 is opened by leverage 3 control valve ports 4 and be closed.

Because the liquid that enters in the shell 1 is oil water mixture, because of both density differences, form obvious separating surface, so ball float 2 just moves between oil-water interfaces.The stressed of ball float 2 is buoyancy (f) and self gravitation (mg), and its hover position and trend that moves up and down in liquid depends on the big or small with joint efforts of above-mentioned two power.Wherein, suffered buoyancy is make a concerted effort contribution, the i.e. f=fo+fw of profit acting in conjunction on ball float.But because oil-water interfaces change up and down in the fluid discharge, corresponding change also takes place in the volume that ball float 2 immerses oil and water, and corresponding change also takes place the size of its suffered gross buoyancy, makes valve port 4 with switch change by leverage 3.

As shown in Figure 1, when oil water mixture has just entered in the shell 1 from liquid inlet 5 along the arrow A direction, oil water surface does not reach ball float 2 height, this moment f=0, under the effect of ball float 2 deadweights, open valve port 4 emptying gas by leverage 3, be beneficial to entering of oil-water mixture body; Along with mixing material flows into, when the separating surface of profit is on position 7 as shown in the figure, f (=fo+fw)＞mg, water can hold in the palm ball float 2, thereby control valve port 4 close, oil is assembled at shell 1 internal upper part; Along with oil is constantly assembled at shell 1 internal upper part, when oil water surface was positioned on the position 8, gross buoyancy reduced, f (=fo+fw)＜mg, this moment ball float 2 will under action of gravity, fall, by leverage 3 valve port 4 is opened, and from liquid outlet 6 along the direction oil extraction shown in the arrow B.Ball float 2 and leverage 3 repeat above-mentioned action and so forth, thereby make oils constantly be discharged away by valve port 4.

As shown in Figure 1, valve port 4 matrixes comprise valve seat 41 and valve rod 46, be symmetrically arranged with suitable first inlet, 42 and second inlet 43 of cross sectional area on the valve seat 41 up and down, valve rod 46 is provided with control first inlet 42 and second inlet 43 first spool 44 and second spool 45 of closure or openness simultaneously.First inlet, 42 and second inlet 43 is up and down mutually to the top, and cross sectional area sizableness, like this, at fashionable first spool 44 of flow of liquid and the suffered difference force sizableness of second spool 45, but direction is opposite, it is made a concerted effort is zero, make valve port 4 can switch under small fluid density difference condition freely, and strengthened the discharge capacity of liquid.

In addition, first and

second spool

44,45 can be designed as taper shape or elliposoidal with first and

second inlet

42,43 faces that match, and can ensure first and

second inlet

42,43 sealing effectively up and down of first and

second spool

44,45 like this.

In addition, as shown in Figure 2, first spool 44 and first inlet also are provided with the grinding faying surface 47 that distributes along circumferentially on 42 faces that match.This grinding faying surface 47 is taper shape or elliposoidal, and its effect provides a continuous face shape sealing surface, guarantees to realize under small pressure the sealing of fluid.Second spool 45 and second inlet also can be provided with identical faying surface on 43 faces that match.

Though the present invention discloses with specific embodiment, but it is not in order to limit the present invention, any those skilled in the art, the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present invention and scope, having done, for example, this device is inverted, is used for the bigger liquid of emission intensity, commonly draining in the oil; Or change ball float mechanism the composition mode, change external shape, change equivalent variations and modification that the conditioned disjunctions such as height setting of liquid level line are done according to scope of patent protection of the present invention, all should still belong to the category that this patent is contained.
