Abstract
The utility model discloses an automatic water-removing valve for a storage tank used for the water-removing of the oil storage tank. The utility model is composed of a floating body (3), a frame rod mechanism [a long arm (6), a pivot point (7) and a short arm (8) ] and a valve cavity (2). When the automatic water-removing valve works, a liquid inlet (1) is connected with the tank. Because the buoyancy is different when the floating body (3) is arranged in oil and in water, when the automatic open water drain and water-removing are completed, the automatic close is realized through the open and close of a bulkhead (9) and a water outlet (10) that are controlled by a lever mechanism.
Description
The utility model relates to a kind of anh basin automatic dehydration of storage tanker valve that is used for.
The oilcan dehydration of petrochemical industry employing at present is manually on duty, and the people happens occasionally for maloperation, causes the oil product loss, causes environmental pollution, brings potential safety hazard, is badly in need of a kind of safe and reliable dehydration control apparatus.
The purpose of this utility model provides a kind of storage tanker bottom that is installed in, can self-opening draining, and the basin automatic dehydration valve that draining can SELF CL after finishing.
Top of the present utility model is provided with inlet, and water outlet is in the bottom, and there are a buoyancy aid and a cover leverage in inside, and buoyancy aid comes the opening and closing water outlet by the rod control plug.Its mechanism is law of buoyancy and the combining of lever principle, and the buoyancy that utilizes the density contrast of different medium in the valve pocket to produce changes, and utilizes leverage to amplify the variable quantity of buoyancy again, thereby realizes the control of buoyancy aid to plug.When the medium in the valve pocket was water, the moment of the suffered buoyancy of buoyancy aid was greater than the suffered differential pressure three's of the gravity of the gravity of buoyancy aid, leverage and plug resultant moment, and water outlet is opened; When the medium in the valve pocket be oily, the moment of the suffered buoyancy of buoyancy aid was less than the resultant moment of the gravity of the gravity of buoyancy aid and leverage, and water outlet is plugged.
The utility model is a kind of basin automatic dehydration valve of novelty, is installed in the storage tanker bottom, can self-opening draining, and draining can SELF CL after finishing, and does not need manual intervention, there is not explosion-proof problem in consumes energy.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing 1 is a structure principle chart of the present utility model.
Inlet (1) is arranged at the valve pocket shown in the accompanying drawing 1 (2) top, water outlet (10) is arranged at the bottom, inside has a buoyancy aid (3) to be connected with long-armed (6) end away from fulcrum (7) by attaching parts (4), clump weight (5) is connected on long-armed (6), fulcrum (7) is fixed on the housing of valve pocket (2), long-armed (6) of captive joint and galianconism (8) can center on fulcrum (7) and rotate, long-armed (6), fulcrum (7) and galianconism (8) are formed a leverage jointly, galianconism (8) is provided with a plug (9) away from an end of fulcrum (7), when buoyancy aid (3) rises or descend, drive plug (9) by leverage and open or close water outlet (10).
For further specifying, earlier the device shown in the accompanying drawing 2 is done some theoretic simplification: 1. the gravity of not considering long-armed (6) and galianconism (8); 2. clump weight (5) merges to buoyancy aid (3) and considers together.
Below principle of work of the present utility model is described with above-mentioned simplified model.
Determine a density value (being called equilibrium point density) between oil and water, the density of selected buoyancy aid (3) equals equilibrium point density.When the Media density in the valve pocket (2) equaled equilibrium point density, the gravity of buoyancy aid (3) equaled its suffered buoyancy, and lever is in state of equilibrium.When Media density changes in the valve pocket (2), the suffered buoyancy of buoyancy aid (3) will change, and buoyancy aid (3) moves up and down.When if the interior medium of valve pocket (2) is water, the suffered buoyancy increase of buoyancy aid (3) moves up, and water outlet (10) is opened; If when the interior medium of valve pocket (2) was oil, the suffered buoyancy of buoyancy aid (3) reduced to move down, water outlet (10) is plugged.
In order to overcome the effect of the differential pressure that is subjected to when plug (9) is blocked water outlet (10), can realize by volume or the brachium ratio of adjusting buoyancy aid (3).
Below the structure principle chart shown in the accompanying drawing 1 is further described.
Clump weight (5) is for regulating the weight of buoyancy aid (3), and controls its sense of motion and be provided with.Owing to there is a clump weight (5), the density of actual buoyancy aid (3) can be less than equilibrium point density, even can be less than the density of oil.Like this, attaching parts (4) can adopt flexible material to buoyancy aid (3) and being connected of stock (6).If cancellation clump weight (5), the attaching parts (4) between buoyancy aid (3) and the stock (6) should possess the buoyancy aid of making (3) bevelled function not substantially, attaching parts (4) can adopt: 1. captive joint with buoyancy aid (3), with stock (6) flexible connection, add the location annex; 2. all captive joint with stock (6) with buoyancy aid (3).
The shape of long-armed (6) and galianconism (8) is arbitrarily, can design as required, as long as satisfy determined brachium ratio.
The orientation setting of galianconism (8) can determine arbitrarily that the orientation of water outlet (10) makes corresponding changes with the orientation setting of galianconism (8), and plug (9) can be blocked water outlet (10) when buoyancy aid (3) was descended.
Leverage is provided with for amplification power, can adopt multipole lever.
Clean for convenience or blowdown, can discharge side be set in addition in bottom of the present utility model, this discharge side is closed at ordinary times.
The utility model is suitable for the sealing basin of opening basin and low static pressure.
The utility model also can be used for the fluid separation applications in other two kinds of non soluble liquids basins.
