This triple valve 160 has the interior pressure of leading to container 101 and regulates the first valve opening 162 of passage 119, leads to and be used to apply and reduce by the second valve opening 163 of pipeline 122 of pressure and the 3rd valve opening 164 that leads to discharge portion.This triple valve 160 has the valve member 165 by control stick 166 hand rotation.As shown in figure 11, according to the position of valve member 165, select gas wherein in first pattern that flows between the first valve opening 162 and the 3rd valve opening 164 or second pattern that between the first valve opening 162 and the second valve opening 163, flows of gas wherein.In this embodiment, as shown in figure 11, be in first operating position, promptly in " 0 o ' clock " time, select first pattern, and the interior exposed of container 101 be in outside air at control stick 166.As shown in figure 12, be in second operating position at control stick 166, promptly when " 9 o ' clock ", select second pattern, and the inside of container 101 is communicated with the pipeline 122 that is used to apply and reduce pressure.
The slewing area of control stick 166 is so limited, that is, 166 of control sticks rotate between first operating position and second operating position.Control stick 166 can be arranged in these operating positions.
The end of rope 144 is fixed on the proximal part of control stick 166.When control stick 166 rotates between first operating position and second operating position, the retaining member 142 that is keeping take-up reel 140 rotates around rotating shaft 141, and take-up reel 140 take-up reel therein 140 be arranged on pipeline 104 outlet 131 belows primary importance and wherein take-up reel 140 between the second place that exports 131 belows retraction, move.
Be arranged on second operating position at control stick 166, promptly during " 9 o ' clock " position, be used to apply and reduce the internal communication of the pipeline 122 and the container 101 of pressure.In addition because rope 144 tensions, so retaining member 142 rotate to container 101 sides, thereby take-up reel 140 is returned merger and is moved to the second place from outlet 131 belows of pipeline 104.Therefore, in this state, can perhaps molten aluminum be supplied to container 101 from the outlet 131 supply molten aluminums of pipeline 104.
Figure 13 is a side view, demonstrates the structure that is used for from the fork truck of the container shown in Fig. 8 101 supply molten aluminums.
Above the driver seat 154 of fork truck 150, be provided with holding vessel 155, air compressor 156 and vavuum pump 157.Holding vessel 155 for Compressed Gas for example compressed air be supplied to the Compressed Gas holding vessel of container 101.Drive this air compressor 156 by the electric energy that produces by the generator (not shown).By generator drive vavuum pump 157.Holding vessel 155 is connected with the pipeline 122 of container 101 by air hose 158 with vavuum pump 157.Air hose 158 and pipeline 122 have connector and the socket as the connector members that can be connected and can disconnect.Can apply and reduce container 101 pressure inside by switch valve by the control of manual operation panel (not shown).
When starting the engine of fork truck 150, generator starts.The electric energy operation air compressor 156 that is produced by generator comes compressed air.When container 101 is supplied molten aluminum to the outside, exert pressure for the inside of container 101.In this case, arrive the air hose 158 and the pipeline 122 of container 101 from the gas of air compressor 156 supplies.In this case, when the control stick 166 of triple valve 160 was in " 9 o ' clock " position as second operating position, this triple valve 160 was in second pattern.As a result, from the pipeline 122 that is used to apply and reduces pressure to container 101 supply gas.Therefore, exert pressure to the inside of container 101.
In emergency, for example at molten aluminum when receiver side flows out, must stop internal pressurization, and stop the supply of molten aluminum to container 101.In this case, with control stick 166 hand rotation to as " 0 o ' clock " position of first operating position, thereby triple valve 160 is in first pattern.When triple valve 160 is in first pattern, closed by valve member 165 owing to lead to the second valve opening 163 that is used to apply and reduces the pipeline 122 of pressure, so stop to the Compressed Gas supply of container 101.Simultaneously, because becoming and to lead between the 3rd valve opening 164 of discharge portion at the first valve opening 162 of the passage 119 that leads to the interior pressure that is used to control container 101, gas flows, so this container 101 is exposed to outside air.Therefore, the compressive state of the inside of container 101 returns to atmospheric pressure.
From the outside to container 101 supply molten aluminums the time, reduce container 101 pressure inside.In other words, since vavuum pump 157 by the pipeline 122 that is used to apply and reduces pressure from container 101 intake-gas and discharge this gas to the outside, so the internal pressure of container 101 reduces.If during reducing pressure in the inside of container 101, be in an emergency, then equally control stick 166 hand rotation are arrived " 0 o ' clock " position, thereby this triple valve 160 is in first pattern as first operating position.
Embodiment according to the front, since with the inside of container 101 and the operation that is used to apply and reduce the pipeline 122 of pressure or the triple valve 160 that outside air selectively is connected, be the primary importance of the manual operation of control stick 166 and outlet 131 belows that take-up reel 140 take-up reel therein 140 is arranged on pipeline 104 and wherein take-up reel 140 leave the motor performance interlocking that exports between 131 the second place, so take-up reel 140 can move to correct position securely in the correct time, and gets involved without operating personnel.
(other embodiment 3)
To describe another embodiment of the invention below.
Figure 14 is a schematic diagram, demonstrates the structure of the peripheral part of triple valve 160 according to another embodiment of the invention.Be arranged on the 3rd valve opening 164 fronts of leading to outside air of triple valve 160 as the ventilation unit 170 of flow restriction part.
This air-breather 170 is made of air-breather main body 171, a steel scrubber and punch metal (punched metal) 173.This air-breather main body 171 includes the steel scrubber 172 as limiting member.Punch metal 173 is for being used for closing the lid of air-breather main body 171.Reference numeral 174 is for being used for fixing the locating snap ring of this punch metal 173.Limiting member is so selected or is constituted, that is, it have for example allow air by and allow the intransitable selectivity of molten aluminum.When for example motlten metal flowed in air-breather main body 171, it removed the heat in the motlten metal so that increase the viscosity of motlten metal or make it curing.Except the steel scrubber, limiting member can be steel wool, ceramic fibre, sintering metal mould, unglazed pottery or porose hardware.This limiting member allows gas pass through and limits the safety component that motlten metal passes through with acting on.
Therefore can prevent that motlten metal from supplying out from the pipeline 104 of container 101 suddenly.In other words, even the interior pressure of container 101 increases owing to gas expansion or water evaporates, pressure also can be discharged into the outside of container 101.Therefore, can prevent that motlten metal is suddenly pressurized and leak out.In addition, even under the situation that container 101 drops, can prevent that also motlten metal from flowing out from the passage with adjustment means.This is because limiting member or the ceramic fibre mould made by for example sintering metal make gas to pass through, but makes for example molten aluminium alloy curing of motlten metal, thereby has prevented the motlten metal outflow.
