Definitions
- the invention relates to a transition component for use between a line system with small flanges and a line system with push-in fittings.
- connection piece with a flange is usually provided at the location of the mouth of the channel ending in the surface of the housing of the vacuum pump.
- the line to be connected to the connecting piece also has a flange.
- the connection itself is established by placing the two flanges on top of one another and fixing them in this position with the aid of a clamping ring or other flange connection components.
- sealing rings made of plastic, rubber or metal are provided for vacuum-tight connections of this type. These are located between the respective sealing surfaces. With the help of grooves, centering rings or the like, they are held in their desired position. The risk of damage to the sealing surfaces on the excellent flanges is high. This also applies to the space required to establish the flange connection, since both hands are necessary to put on and fasten a clamping ring or other flange connection components.
- control systems with push-in fittings which have so far only been used in compressed air technology (see, for example, push-in fittings from Camozzi Pneumatik). They consist of a first threaded section and a second, approximately cup-shaped section, which enables a tight, detachable connection to the free end of a plastic tube or hose.
- the tube is inserted into the pot-shaped section with one hand until it passes through an O-ring located inside the component and has reached a mechanical stop.
- Part of the pot-shaped section is a sleeve-shaped collet acting on the circumference of the plastic tube, which can be released by an axial movement.
- connection lines consist of a flexible material (e.g. plastics, such as polyamide, polyurethane, etc. or rubber).
- this goal is achieved by means of a transition component which makes it possible to use line systems with push-in fittings in line systems or devices designed with small flanges.
- This transition component has the characteristic features of the claims.
- the present invention is based on the knowledge that the easy-to-use line systems with push-in fittings have surprisingly proven to be vacuum-tight. It was therefore only necessary to use the transition component according to the invention in order to make the two line systems compatible with one another.
- the transition component 1 shown in the figure consists of a vacuum flange adapter 2 with a cylindrical section 3, which is located on the side opposite the sealing surface 4 of the flange 2.
- Adapters of this type have previously been used e.g. used as a hose nozzle.
- the cylindrical section 3 is equipped with an internal thread 5 into which the threaded section 6 of a plug connection screw 9 is screwed tight.
- Many other vacuum-tight connections between the flange adapter and push-in fitting e.g. welding, soldering, other thread designs
- the use of the thread that is already present on commercially available push-in fittings is particularly simple.
- the second section 11 of the push-in fitting 9 is cup-shaped in a manner known per se. It receives an O-ring 12, a collet 13 and the free end of a connecting line 14.
- the collet is a sleeve slotted on the O-ring side with a bead 15 facing the O-ring 21, to which an incline 16 is assigned on the inside of the pot-shaped section.
- the slope 16 is designed such that it causes the line 14 inserted into the sleeve 13 to be braced when a tensile force is exerted thereon. This tension is released by axially moving the collet 13 in the direction of the O-ring 12.
- the described and illustrated transition component makes it possible to connect systems or devices equipped with flanges to line systems equipped with push-in fittings 9.
- the push-in fitting 9 described has proven to be vacuum-tight under the conditions that the flexible material of the line 23 is suitable for enduring temperatures up to 80 ° C.
- its surface roughness must be able to be selected such that the line 23, together with an O-ring 21 usually used in vacuum technology, can ensure a vacuum-tight separation. This is the case with a roughness of less than or equal to R z 16, preferably R z 10. Surfaces from R z 4 to R z 16 should also be free of cross grooves.
