Definitions
- the invention relates to a sealing head for temporarily closing gas-tight openings, with a base plate on which a peripheral seal is held closed in the circumferential direction.
- sealing heads are generally used, which on the one hand have a base plate corresponding to the geometry (shape and size) of the opening to be sealed, which is usually made of metal, and on the other hand have a suitable circumferential seal which is connected to the base plate and which, in known designs, has an O-ring is formed.
- an exhaust opening can be temporarily closed in a gas-tight manner by pressing a sealing head with a seal that is slightly larger than the exhaust opening against the sealing surface surrounding the exhaust opening, with any slight unevenness, roughness, etc. can be compensated for by the elasticity of the O-ring. Then, for example, compressed gas can be introduced into the cylinder space via an inlet opening, which can also be done with the aid of a sealing head, which has an opening and a supply line connected to it, and otherwise closes the inlet opening.
- Such sealing heads have proven themselves in practice in principle, but are disadvantageous in that their sealing effect with large excess pressures and / or unevenness or roughness in the area of the sealing surface is considerably reduced, so that considerable contact pressures are required to ensure a perfect sealing effect the forces resulting from the static internal pressure often exceed many times.
- the object of the invention is therefore to improve a generic sealing head in such a way that a perfect sealing effect even with certain bumps or roughness in the area of the sealing surface and thus a certain bridging ability can be achieved without a considerable contact pressure.
- This object is achieved in a generic sealing head in that the seal is designed as a flexible lip seal, the sealing lip in the unloaded state protrudes from the base plate such that it is directed to an inner region of the sealing head enclosed by the sealing lip.
- this surprisingly simple measure achieves a considerable bridging ability of unevenness with a practically negligible pressing force.
- the arrangement is preferably such that the sealing lip protrudes from the base plate at an acute angle.
- the invention preferably provides that the sealing lip protrudes from the base plate at an angle of approximately 30 ° to 60 °, preferably approximately 45 °.
- the sealing lip can be vulcanized or glued to a flange-like projecting web of the base plate.
- the sealing lip preferably consists of an elastic material, for example rubber or an elastomer.
- the sealing lip has a tapering cross section.
- the sealing lip extends in one plane.
- the sealing lip extends along a curved, in particular cylindrical jacket-shaped surface, for example in order to seal openings which lie directly in a cylindrical wall.
- the base plate also extends along a curved, in particular cylindrical jacket-shaped surface.
- the base plate has at least one opening and / or at least one compressed gas connection in order to discharge or supply a compressed gas in a controlled manner.
- the base plate is preferably made of metal or plastic. As a modification, it can be provided that the base plate and lip seal are made in one piece from a suitable plastic.
- FIG. 4 shows a top view of a sealing head according to the invention
- Fig. 2 shows a sectional view along line II-II in Fig. 1, and
- FIG. 3 shows an enlarged detailed illustration of the lip seal from FIG. 2.
- FIG. 1 to 3 illustrate an embodiment of a sealing head according to the invention which, with a closed base plate 1, that is to say no openings, has an oval basic shape with an inner side 4 enclosed by a projecting web 3.
- a lip seal 5 is inserted from the inside against the web 3 of the base plate 1 and overlaps it with a flange-like extension 6, the lip seal 5 being used is moderately glued to the web or vulcanized to it, provided that it is made of rubber.
- the lip seal 5 has a sealing lip 7 protruding toward the inside 4 of the base plate 1, which is tapered and is at an angle ⁇ of approximately 45 ° to the plane of the inside 4.
- the sealing head is first placed in use in the direction of arrow 8 against the sealing surface 11 of a device to be checked for tightness, which surrounds an opening 10 to be sealed, with a very low pressing force, for example in the range from 5 to 10 N for a sealing head with an average diameter of about 5 cm is sufficient.
