Abstract
The utility model discloses a sealing device for a cylinder port made of a composite material. The sealing device comprises a cylinder, one end of the cylinder is provided with an upper flange, and the upper flange is provided with two vacuum valves. An inner liner ring is arranged between the inner surface of the cylinder and the upper flange. A lower flange is arranged on the outer surface of the cylinder and under the upper flange. A sealing gasket is provided between the upper flange and the lower flange. The upper flange and the lower flange are connected through a plurality of screws on the circumference. The sealing device can seal the cylinder port made of the composite material well and no leaking point is found after leakage detection with a helium mass spectrometer.
Description
Technical field
The utility model belongs to a kind of vacuum sealing device, is specifically related to a kind of packoff of the cylinder port of making of compound substance.
Background technology
Be used widely in engineering by advantage because its specific modulus and specific strength height, designability be good etc. for compound substance, comprising common composite material pressure container and high speed rotor, the cylinder that this class is made of compound substance also will be considered specific condition and the environment of its application when sufficient intensity is provided, often there is the material that does not allow to external leakage its inside, strict sealing property need to be arranged with the cylinder itself that compound substance is made, play buffer action to external world.Therefore, need the impermeability of the cylinder made of compound substance be detected.So design one cover is suitable for the experimental provision with the cylinder port sealing of compound substance making, guarantees the sealing of port, and then can detect the impermeability of the cylinder of making of compound substance.
Summary of the invention
The utility model proposes in order to overcome the shortcoming that exists in the prior art, its objective is the packoff that a kind of cylinder port of making of compound substance is provided.
The technical solution of the utility model is: a kind of packoff of the cylinder port of making of compound substance, comprise cylinder, and be provided with upper flange at an end of cylinder, upper flange is provided with two vacuum valves.
Between cylinder inner surface and upper flange, be provided with inner bushing ring, below cylinder outer surface, upper flange, be provided with lower flange, be provided with sealing gasket between cylinder outer surface, upper flange and the lower flange, between upper flange and lower flange, connect with a plurality of screws along circumference.
The other end of cylinder adopts above-mentioned same port sealing device.
The obtained beneficial effect of the utility model is:
The utility model can well now seal in the cylinder end cause for gossip of making of compound substance, visits by helium mass analyzer and does not leakage find leak source.
Description of drawings
The packoff sectional view of Fig. 1 cylinder port that to be the utility model make of compound substance.
Among the figure:
1 cylinder, 2 sealing gaskets
3 inner bushing rings, 4 lower flanges
5 upper flanges, 6 vacuum valves
7 screws.
Embodiment
Below, with reference to drawings and Examples the packoff of the utility model with the cylinder port of compound substance making is elaborated:
As shown in Figure 1, a kind of packoff of the cylinder port of making of compound substance comprises cylinder 1, is provided with circular upper flange 5 at an end of cylinder 1, and upper flange 5 is provided with 6, two vacuum valves 6 of two vacuum valves and keeps at a certain distance away.
Between cylinder 1 inside surface and upper flange 5, be provided with circular inner bushing ring 3, below cylinder 1 outside surface, upper flange 5, be provided with lower flange 4.Between cylinder 1 outside surface, upper flange 5 and lower flange 4, be provided with sealing gasket 2, between upper flange 5 and lower flange 4, connect with a plurality of screws 7 along circumference.
The other end of cylinder 1 adopts above-mentioned same port sealing device.
The course of work of the present utility model is as follows:
Before the experiment beginning, one is communicated with evacuating equipment, a connection cylinder vacuum checking device in two vacuum valves, is evacuated to certain vacuum tightness, closes the vacuum valve that is communicated with evacuating equipment, behind the system stability certain hour, the reading of the vacuum meter of record vacuum checking device.Use helium mass analyzer to detect the sealing situation at sealing surface place.
The utility model can well now seal in the cylinder end cause for gossip of making of compound substance, visits by helium mass analyzer and does not leakage find leak source.
