Definitions
- the invention relates to an arrangement for preventing Leakage of liquids from line openings.
- Such Lines are used, for example, in manufacturing from semiconductor wafers to these treatment liquids to apply.
- Such lines are e.g. in etching devices as described in EP 0 444 714 B are used.
- Valves are often used which suck back a small amount of liquid when closing.
- these valves with a 1 ⁇ 4-inch hose (inside diameter approx. 5 mm, cross section approx. 0.2 cm 2 )
- suck-back valves suck the liquid column back approx. 10 cm, which is approx. 2 ml liquid.
- a 1 ⁇ 4 inch hose results in a flow rate of approx. 2 m / sec. Since silicon wafers are getting bigger (currently diameters up to 300 mm), an ever increasing volume flow is necessary for the treatment. Volume flows of up to 6 l / min are currently required.
- a dosing device is known from EP 402 535 B1 a valve, an adjustable piston and at the outlet opening has a porous insert.
- the piston moves after the Closing the valve away from the outlet opening, so that in the Area of the outlet opening creates negative pressure, the liquid should prevent dripping out of the outlet opening.
- DD 250 846 A3 there is a chamber valve for drip-free Closing liquid containers described, the of of the liquid to be dosed through a chamber Cuff is formed.
- the cuff is open Valve compressed (small interior of the chamber) and at closed valve stretched (large interior of the chamber).
- the chamber is created by increasing its volume when Closing the valve (stretching the cuff) a negative pressure, causing the liquid to withdraw from the exit opening becomes.
- the liquid remains with the valve according to DD 250 846 A3 in the chamber of the valve and / or in the area between the outlet opening and valve. Gassing liquids would drip this facility anyway.
- the object of the invention is to provide an arrangement with which the dripping, even with high volume flow and / or when conveying liquids containing gas, is reliably prevented.
- the above object is reliable solved and dripping from line openings in particular even with high volume flow and in the case of gas containing Liquids reliably prevented, as liquid is immediate is sucked away in front of the outlet opening of the line, so that liquid no longer comes out of the opening of the line can leak (drip).
- this is all about Exit opening provided a chamber that in due course is subjected to negative pressure.
- FIG. 1 shows a section of an arrangement according to the invention, a section along the line B-B in Fig. 2, Fig. 2 along the line A-A in Fig. 1 and Fig. 3, for example Embodiment of the circuit of the arrangement according to the invention.
- shut-off device cf. FIG. 3
- suction valve suction-back valve
- the line 2 is one Device 1 assigned, which is used to prevent dripping Liquid from the outlet opening 6 to the line 2 prevent.
- On the housing 4 is one Line 5 connected via the negative pressure in the chamber 3 can be generated.
- the line 5 with a Vacuum source (see. Fig. 3) connected, in which to Vacuum source leading line 5 shut-off devices provided could be.
- the through openings 7 In the wall of line 2 are in the area of Chamber 3 several through openings 7 (in principle, one is sufficient only through opening 7) is provided.
- the through openings 7 can be designed as a perforation, that is a very have a small diameter.
- the distance of the area, in which the through openings 7 are provided in the pipeline 2 are, from the outlet opening 6 of the line 2 can be any be chosen small.
- measures can be provided with which the Passages 7 closed in the wall of line 2 when liquid flows through line 2.
- Such Measures can be shut-off devices, e.g. in form of a relative to the end of the line 2 rotatable sleeve in which Holes are provided. If the sleeve is turned so that the holes in the sleeve are aligned with the passage opening 7, acts the negative pressure in the chamber 3 for suction of liquid residues.
- FIG. 3 A possible circuit, like the device 1 only when needed made effective, that is, the chamber 3 is subjected to negative pressure can be shown in Fig. 3.
- Line 8 is a compressed air line that divides into two branches.
- the simultaneous shutdown of the liquid flow 9 in the Line 2 and switching on the negative pressure in chamber 3 can be ensured in the following way.
- Via a venturi nozzle 12 is with the compressed air flow 11 in one branch of the Compressed air line 8 generates a suction stream 10 that the chamber 3 applied with negative pressure.
- the valve 13 for the liquid flow can, but does not have to be designed as a return valve.
- the vacuum can be generated by a vacuum pump.
- the suction flow is via its own valve switched. The simultaneous shutdown of the liquid flow and switching on of the suction flow takes place in this Case e.g. electric.
- Droplet suction device 1 To prevent liquid from dripping out of the outlet opening 6 to prevent a line 2 is the end of line 2 one Droplet suction device 1 assigned.
- the droplet suction device 1 has a housing 4, which is the end of the line 2 surrounds to form a chamber 3.
- Chamber 3 stands with the inside of the line 2 through openings 7 in Connection and can be used for suction in the area of the outlet opening 6 after switching off the liquid flow through the line 2 remaining liquid residues a line 5 are subjected to negative pressure. It will proposed a circuit which the droplet suction device 1 only starts up, e.g. the chamber 3 with negative pressure acted upon when the liquid flow through line 2 interrupted by a shut-off device assigned to line 2 is.
