Definitions
- Valve in particular Vakuu mventil
- the present invention relates to a valve, in particular a vacuum valve, with at least one closure member for closing a valve opening and with at least one valve rod, wherein at least a first connecting portion is arranged in or on the valve rod and at least a second connecting portion is arranged in or on the closure member and the Closing member by connecting the first connecting portion with the second
- Connecting portion on the valve rod can be fastened or attached.
- DE 0 2012 007 533 A1 shows, for example, a variant in which the closure member on the interaction of a
- EP 2 146 122 A1 discloses a variant in which separate clamping pieces are used to fasten the closure member to the valve stem.
- the US 7, 134,642 B2 shows a solution in which the closure member is attached to the valve rod by means of a screw.
- valves especially when used in vacuum technology, it is an important aspect that as few particles as possible are generated by abrasion in the valve itself, since these particles are the processes that are carried out in process chambers, which open and close the valves, can disturb.
- valves on valves occasionally require service or replacement.
- the closure member usually has to be released from the valve stem.
- the use of screwed connections for this purpose has the problem that particles are produced or released in particular by rubbing heads of the screws on the bearing surfaces on which they rest can be. Also problematic are inclined surfaces, as shown in DE 10 2012 007 533 A1, on which the components rub against each other when opening and closing the connection. Again, particles can be generated by abrasion.
- the object of the invention is to propose an alternative possibility for a valve of the above type, as the two connecting portions connected to each other and thus the closure member can be attached to the valve stem.
- the invention proposes in a valve of the above-mentioned type that the first connecting portion and / or the second connecting portion has at least one, bounded by at least one elastically deformable boundary wall, pressure chamber for a fluid and have the boundary wall for training a clamping connection of the first connecting portion with the second connecting portion is elastically deformable by means of the fluid arranged in the pressure chamber.
- a basic idea of the invention thus provides that in at least one of the two connecting sections a pressure chamber with at least one elastically deformable boundary wall is provided, wherein the boundary wall can be elastically deformed by corresponding pressure buildup by means of a fluid in the pressure chamber and thus deflected so that thereby a clamping connection of the first connecting portion with the second
- the pressure chamber with its at least one elastically deformable boundary wall can be arranged both part of the first connection portion and thus in or on the valve rod, but also part of the second connection portion and thus in or on the closure member. Variants are also conceivable in which both the first connection section and the second connection section each have at least one pressure chamber with at least one correspondingly deformable boundary wall.
- deformable boundary wall can thus be part of the first connection portion but also be part of the second connection section.
- the boundary wall wherever it is arranged, can be elastically deformed by corresponding pressure buildup in the fluid in the pressure chamber such that a clamping connection of the first connection section to the second connection section occurs.
- this clamping connection is a detachable connection.
- the connection is achieved by lowering the pressure in the fluid in the pressure chamber so that the elastic restoring forces of the boundary wall bring it into a position in which the clamping connection is released, so that the second connection section from the first connection section and thus the closure member of the
- Valve rod can be removed.
- valves according to the invention can have only one closure element and only one valve rod and only one first connection section and only one second connection section. But there are others too

- the valve rod is a connection between the closure member and at least one valve drive of the valve. Valve rod and closure member are often shared by
- Valve drive moves to bring the closure member in its closed position or in its open position. It should be noted that the valve, depending on how many directions of movement the closure member between the closed position and the maximum open position is moved, may also have a different number of Ventiiantrieben.

- at least one valve seat to which the closure member is pressed in the closed position, runs around the valve opening. Between the valve seat and Verschiussorgan located in the closed position usually at least one seal. This can be arranged both on the closure member and the valve seat. Variants are also conceivable in which at least one corresponding seal is present both on the closure member and on the valve seat.
- the second connecting portion may be directly part of the closure member and thus arranged in the closure member. But they are also inventive
- Closing member is arranged. This can e.g. then be the case if that
- Closure member is fixed to a closure member carrier and the
- Closing member carrier has the second connecting portion, with which the closure member is attached to the valve rod and its first connecting portion. The same applies to the valve stem and the first

- valves according to the invention may be so-called vacuum valves, which are used in vacuum or vacuum technology or for these are provided.
- vacuum technology such valves are often used to open and close process chambers.
- process chambers as is known, special, needed for the process,
- Vacuum valves are valves that are designed for these pressure ranges and / or corresponding pressure differences to the environment. But you can also speak of vacuum valves in general when they are designed for pressures below atmospheric pressure below 1 bar.

- Closing member or the closing organ fixed to the closure member carrier has the receiving cavity, which is surrounded by the second connecting portion.
- the closure member carrier can be rigidly and fixedly attached to the closure member. But it can also be provided that the valve rod or on the Valve rod fixed additional part has the receiving cavity, which is surrounded by the first connecting portion.
- corresponding pressure build-up in the pressure chamber is elastically deformable, is part of one of the connecting portions and in preferred variants of this aligned so that they at least a part of the outer wall of this
- Connecting portion forms, which points to the production of the clamped connected state to the other connecting portion. This is especially true for the variants with receiving cavity, but can also be realized in other variants preferred.
- At least one of the connecting sections has a seal, with which the receiving cavity is sealed to the outside, when the
- Connecting sections are in the clamped connected state.
- valves In order to be able to fill the pressure chamber with fluid and optionally also to be able to pressurize accordingly, preferred variants of valves according to the invention provide that the valve has a shut-off element for locking the fluid in the pressure chamber.
- a shut-off element for locking the fluid in the pressure chamber.
- this is a detachable, ie by hand or by means of a tool, non-destructively releasable shut-off, which serves to lock the fluid in the pressure chamber, but to be able to discharge from this again.
- the shut-off element is designed as an adjusting element for adjusting the pressure of the fluid in the pressure chamber.
