Description

Crude oil storage container and automatic drainer

The utility model relates to a kind of freeing arrangement of crude oil reservoir vessel, especially can realize getting rid of automatically the crude oil reservoir automatic water trap of moisture content according to the profit difference of pressure.

At present, known draining way is according to after the profit static layering, and the drain hose by crude oil reservoir vessel bottom side carries out manual emission, and it exists labour intensity big, is difficult for grasping displacement, and the waste oil plant is prone to accidents.

The purpose of this utility model provides a kind of crude oil reservoir automatic water trap, and it can get rid of the moisture content in the crude oil automatically.

The purpose of this utility model is to realize like this; The big housing that coolant inlet pipe is installed constitutes one with the small shell that drain hose is installed, be provided with the spool of passage at the inner chamber of big housing, inlet opening (8) by connecting duct and small shell joins, float is connected on the spool by the float sheathed catheter of its centre, and can do along spool and pump, top side at the float conduit is equipped with rubber cushion, and can contact with the porthole of spool, the diaphragm that constitutes one with valve plug and pressing plate is fixed between the loam cake and bottom of small shell, valve plug can be done and pump, and can contact with the primary valve on the housing bottom side, being provided with drain gutter in the bottom side of bottom, blind flange is fixed on the big housing.

Owing to adopt such scheme, can realize the opening and closing of valve plug according to the profit differential static pressure in the oil vessel automatically, the moisture content with oil vessel excludes automatically, and its volume is little, and is simple in structure, safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a constructional drawing of the present utility model.

In the embodiment shown in fig. 1, the big housing (7) that coolant inlet pipe (1) is installed constitutes one with the small shell (9) that drain hose (16) are installed, and be positioned at the bottom side of big housing (7), be provided with the spool (3) of passage at the inner chamber of big housing (7), join by the inlet opening (18) of connecting duct (8) with small shell (9), float (5) is socketed on the spool (3) by the float conduit (4) of its centre, and can do along spool (3) and pump, in the top side of float conduit (4) rubber cushion (2) is installed, and can contact with the porthole of spool (3), bottom side at big housing (7) is provided with primary valve (13), copper sheathing (14) is embedded in the primary valve (13), the diaphragm (10) that same valve plug (15) and pressing plate (12) constitute one is fixed between the loam cake and bottom (17) of small shell (9), the diameter of pressing plate (12) is greater than the diameter of primary valve (13), valve plug (15) can be done and pump, and can contact with the primary valve (13) on the housing bottom side, be provided with drain gutter (11) in the bottom side of bottom (17), the diameter of inlet opening (18) is greater than the diameter of drain gutter (11), flange (19) is fixed on the big housing (7), inner chamber at big housing (7) is provided with float bowl (6), and coolant inlet pipe (1) joins with the drain hose that oil storage is held.Principle of work is: when being full of oil in the float bowl (6), the weight of float (5) is greater than the buoyancy of oil, the rubber cushion (2) of float (5) top side and the porthole closed contact of spool (3), closed the passage in spool (3) inner chamber, pressure in the loam cake in the small shell (9) is greater than the pressure in the bottom (17), forcing diaphragm (10) to drive valve plug (15) moves downward, valve plug (15) and primary valve (13) close proximity are touched, oily impassabitity primary valve (13) in the float bowl (6) is discharged from, and by in coolant inlet pipe (1) the backspace oil vessel, when the moisture content in the oil vessel constantly enters float bowl (6), water level in the float bowl (6) constantly rises, the buoyancy of float (5) also increases thereupon, when buoyancy during greater than the weight of float (5), float (5) is along spool (3) upward movement, the rubber cushion (2) of float (5) top side and the porthole of spool (3) are separated, make the moisture content in the float bowl (6), just successively by the gap of float conduit (4) with spool (3), passage in spool (3) inner chamber, connecting duct (8) and inlet opening (18) and enter in the inner chamber of bottom (17), because inlet opening (18) diameter is greater than the diameter of drain gutter (11), cause the moisture content in bottom (17) inner chamber also to be on the increase, to the greatest extent the pressure of bottom (17) inner chamber is constantly increased, until pressure near the oil vessel bottom, secondly since the diameter of pressing plate (12) greater than the diameter of primary valve (13), make the pressure of the pressure of bottom (17) inner chamber greater than last cover cavity, impel diaphragm (10) to drive valve plug (15) upward movement, valve plug (15) and primary valve (13) are separated, make the moisture content inner chamber by valve plug (15) and the formed gap of primary valve (13) and loam cake successively in the float bowl (6), passing through drain hose (16) at last is discharged from outside the big housing (7), in brief, oil in the oil vessel constantly enters again in the float bowl (6), under the action of gravity of float (5), the rubber cushion (2) of float (5) top side is contacted with the porthole of spool (3), valve plug (15) contacts with primary valve (13), make path be in closed condition, the moisture content of oil vessel constantly enters again in the float bowl (6) thereupon, under the effect of buoyancy of water, the rubber cushion (2) of float (5) top side and the porthole of spool (3) are separated, valve plug (15) and primary valve (13) are separated, make path be in opening, cause the moisture content in the float bowl (6) to be excluded, in like manner go round and begin again, till the moisture content in the oil vessel is excluded.
