CN2233491Y - Liquid under interface discharging valve - Google Patents

Abstract

The utility model relates to a device which is used for separating two kinds of liquid in a vessel or for separating the gas and the liquid in a vessel. The device is composed of a pipe shell, the upper and the lower ends of which are provided with flanges, wherein, a liquid distributing plate, a liquid inlet pipe, a liquid outlet pipe and two conical tub type float valve cores are arranged in the pipe shell. The utility model is designed by taking the Archimedes law as the theoretical foundation and using the characteristic that the specific gravity of the liquid under interface is bigger than the specific gravity of the liquid above the interface. When the utility model is adopted, the additional energy source or the manual operation are not needed, and the accidents which are caused by the misoperation or the malfunction of an instrument can be avoided.

Description

Liquid expulsion valve under the interface

The utility model is a kind ofly to be used in the SEPARATOR OR SEAL CHAMBER two kinds of liquid or with the equipment of gas in the container and liquor separation.

Make at petrochemical industry, petroleum processing, medicine.Industries such as oil chemistry, no matter be in the production process of fluid product, situation in the same system of two kinds of incompatible liquid (or gas-liquid) coexistence still may appear in the middle part of the transporting procedures of fluid product, people are if think therefrom to isolate a certain liquid, mostly come switch to cut fluid valve by artificial or automatic controller and realize, above-mentioned way is often run the generation of emitting accident because of malfunctioning the causing of artificial reason or automatic controller.

The purpose of this utility model provides a kind of under unattended condition, automatically the equipment that liquor separation under the container inner boundary is gone out.

The automatic expulsion valve of liquid is to be rationale with the Archimedes' principle under the utility model interface, utilizes that under the interface liquid specific gravity forms greater than this characteristic design of liquid specific gravity on the interface.

The valve body of liquid expulsion valve is that up and down two ends have the shell of flange under the utility model interface, part two-part up and down in the shell, and top has 1 grade of micropore plate that gathers.Liquid distributing board, the secondary micropore plate that gathers, valve core inflow pipe distribution grid suitable for reading, valve core end opening drain pipe distribution grid, drain pipe distribution plate and cone bucket type float flap, the shell bottom is by liquid distributing board, the micropore plate that gathers, valve core inflow pipe distribution grid suitable for reading, the valve core end opening goes out the liquid-in pipe distribution grid, the drain pipe distribution plate, liquid outlet plate and cone bucket type float flap are formed, cone bucket type float flap top drum passes liquid distributing board and the densely covered plate of micropore, valve core inflow pipe distribution grid suitable for reading and valve core end opening go out to be communicated with a liquid-in pipe between the liquid-in pipe, and connect into a taper valve core with the sealed nylon ring, the valve core end opening goes out between liquid-in pipe distribution plate and the drain pipe distribution plate to be communicated with a drain pipe, vacuum appears for preventing to cause when liquid breaks away from lower valve chamber, an external inert gas is filled one-way valve at the shell middle part, and a unidirectional gas charging valve is with in cone bucket type float flap bottom.

Below in conjunction with an attached explanation embodiment of the present utility model.

Accompanying drawing is the schematic representation of liquid expulsion valve under the utility model interface, and numeral wherein is: 1, housing, 2, valve core, 3, unidirectional gas charging valve, 4, flange, 5, the I level micropore plate that gathers, 6, cone bucket type float flap, 7, the nylon guard ring, 8, liquid distributing board, 9, the II level micropore plate that gathers, 10, valve core inflow pipe distribution grid suitable for reading, 11, liquid-in pipe, 12, the valve core end opening goes out the liquid-in pipe distribution grid, 13, the inert gas filling-valve, 14, liquid distributing board, 15, the micropore plate that gathers, 16, drain pipe, 17, the valve core end opening goes out the liquid-in pipe distribution plate, 18, liquid distributing board, 19, the drain pipe distribution grid, 20, inflow pipe, 21, valve core liquid-in pipe distribution plate suitable for reading, 22, valve core, 23, the float flap, 24, drain pipe, 25, the drain pipe distribution plate, 26, unidirectional gas charging valve.

Bis among the figure is expressed as: increasing of A, last valve chamber hinders the step-down liquid distribution chamber, B, the spacing chamber of cone bucket type float, C, the valve core chamber of going up valve chamber, D, valve core end opening liquid storage power house, E, inert gas filling station, F, the spacing chamber of cone bucket type float, the spacing chamber of cone bucket type monkshood of G, lower valve chamber, the valve core chamber of H, lower valve chamber, the liquid storage power house of I, lower valve chamber, J, liquid are dredged out the chamber.

Float flap in the present embodiment designs according to density of liquid characteristic under the interface, that is to say that having only this liquid to reach just can make the flap come-up under a certain amount of condition, open wide valve core, make outside this liquid output system, when being less than by lyophobe when a certain amount of, flap sinks, valve core is closed, termination liquid is discharged, thereby has reached the purpose of separating, and has prevented the accident that liquid is misprinted out on the interface again.

Entered the A chamber by the discharge opeing body through the resistance step-down that increases of the densely covered plate (5) of I level micropore under the interface, enter the B chamber by liquid distributing board (8), enter the C chamber by II level micropore distribution grid (9) again, enter the E chamber by liquid-in pipe (11) then, float flap this moment (6) immerses among the liquid fully, at the buoyancy function float downward, leave valve core (2), make the C chamber, the flow direction D chamber of E chamber, flow into the F chamber by drain pipe (24), enter the G chamber through liquid distributing board (14) then, enter the H chamber by the densely covered plate of micropore again, enter the J chamber through liquid-in pipe (20) again then, this moment, the float flap floated, liquid is from the J chamber, after the H chamber enters the I chamber, guide (K) chamber into from drain pipe (16) again, by the K chamber outside liquid outlet plate (19) discharge system.

Use that the automatic expulsion valve of liquid does not need any external energy to be power under the utility model interface, owing to adopted bivalve chamber, two float flap, two groups of runners, combination up and down, the structure of dredging for twice, thereby stopped the possibility that liquid is carried away on the interface fully, avoided because the generation of the accident that misoperation or instrument malfunction cause.
