Definitions
- the invention relates to a connection device for a vacuum system.
- Such connecting devices are used in the connection of assemblies such as vacuum chambers, pumps, etc. through lines. They must be vacuum-tight, even if the connected parts have manufacturing tolerances, vibrations are exposed and subjected to different thermal expansions. In addition, they must withstand corrosive gases, such as those used above all for the cleaning of system parts.
- a known generic connection device which is described in more detail below, comprises a bellows made of metal, e.g. corrosion-resistant spring steel, INCONEL or aluminum, which ensures the required flexibility.
- metal e.g. corrosion-resistant spring steel, INCONEL or aluminum
- Such connecting devices have proven themselves, but are very expensive, especially when a bellows from INCONEL is used.
- the invention is based on the object to provide a generic connection device, which is also releasable and reliable gas-tight and offers sufficient flexibility, but can be made much cheaper.
- This object is solved by the features in the characterizing part of claim 1.
- the connecting device according to the invention can be easily produced and adjusted when the system is stationary, but nevertheless provides a reliable gastight seal both under operating conditions and outside the operating times. Under operating conditions, it is stable against corrosive gases. The cost savings over known generic
- Connecting devices is considerable. It can be 50% or more.
- FIG. 1 shows a longitudinal section through a known generic connection device
- Fig. 2 shows a corresponding longitudinal section through an inventive connecting device, which represents only one embodiment.
- the known generic connection device has a bellows 1 made of metal, eg corrosion-resistant spring steel, INCONEL or aluminum, one end, the opening surrounding the opening, with the flange 2 and the other end is welded to a ring 3, which also by a screw 4 is connected to the flange 2.
- the ring 3 is also releasably connected by a screw 5 with a piece of pipe 6, but gas-tight.
- the bellows 1 allows movement of the ring 3 relative to the flange 1 both in the longitudinal direction as well as limited across.
- the additional mechanical connection through the screw 4 with at least one bolt, which is surrounded by a compression spring and is biased by it, is designed so that it does not affect these possibilities.
- the connecting device 15 comprises two flanges 10, 11 each having a pipe section or pipe socket 16 arranged thereon; 18, which are arranged one inside the other, that the pipe section 16 and the pipe socket 18 are aligned on at least a partial section substantially coaxially and enclose a circumferential annular gap.
- a main sealing ring 12 made of plastic, preferably Teflon is arranged in this annular gap (on the said section) between the outer surface of the pipe section 16 and the inner surface of the tube piece 16 surrounding raw pipe 18, a main sealing ring 12 made of plastic, preferably Teflon is arranged. It is dimensioned so that in said portion of an inner sealing surface of the same abuts against the outside of the pipe section 16 and an outer lateral surface on the inside of the pipe socket 18.
- an auxiliary seal between the pipe section 16 and the pipe socket 18 used, for example a radial shaft seal 13.
- the pipe piece 16 heats up to an operating temperature which, for example, is reached. 50 ° or more, above the ambient temperature.
- Plastic, in particular Teflon, the preferred material for the main seal ring 12 is a very good thermal insulator, so that the pipe socket 18 remains substantially at ambient temperature, resulting in a temperature difference between the same and the pipe section 16.
- the pipe section 16 expands and presses against the inner sealing surface of the main sealing ring 12, the outer surface thereof is thereby pressed against the inside of the pipe socket 18. This causes the connection pipe socket 18 -
- Main seal ring 12 - pipe section 16 is gas-tight or vacuum-tight and the underlying radial shaft seal 13 against aggressive gases such. Fluorine is protected. The possibility of expansion in the longitudinal direction of the pipe section 16 and the pipe socket 18 is still guaranteed. Experiments even showed a higher tightness of the connecting device according to the present invention as the welded solution according to the prior art.
- Inconel bellows can achieve cost savings of> 50%.
- the production of turned and milled parts is less expensive than the known design of the connecting device.
- a spring-clamped with a spring screw 17 fulfills the same function as the screw 4 in Fig. 1st
