Description
Technical field
The utility model relates to a kind of vacuum components, and in particular to a kind of practical vacuum all-metal quick locking
Sealing device.
Background technique
Vacuum sealing belongs to the vacuum component that Vacuum Field largely uses, and existing vacuum sealing is many kinds of, but for
Needing to complete the connection sealing of flange under vacuum conditions, when connection, uses screw to be compressed repeatedly one by one with nut more,
Cause the time for compressing needs long, working efficiency is low, when dynamics occurs uneven when compressing one by one, just will appear bonding in vacuum
Offset, leads to vacuum leak.
Therefore, it is necessary to designed and developed in prior art basis it is a kind of reasonable in design, it is easy to use, it is especially suitable
Sealing device for quick locking under vacuum conditions.
Utility model content
In order to solve the deficiencies in the prior art, the purpose of the utility model is to provide a kind of reasonable in design, users
Just vacuum all-metal quick locking sealing device, is particularly suitable for quick locking sealing device under vacuum conditions.
In order to achieve the goal above, technical solution adopted in the utility model are as follows:
A kind of vacuum all-metal quick locking sealing device, including metal tube 1, metal pipe expanding mouth 1-1, nut 2, flange knife
Mouth 3-1 and flange seat 3；1 lower end of metal tube is equipped with metal pipe expanding mouth 1-1, and 3 upper end of flange seat is equipped with flange edge of a knife 3-
1, the metal pipe expanding mouth 1-1 and flange edge of a knife 3-1 are compressed, by nut 2 that metal pipe expanding mouth 1-1 and flange edge of a knife 3-1 is fast
Speed locking, realizes metal tube 1 and the all-metal fast sealing of flange seat 3 under vacuum conditions.
On the basis of above scheme, the metal tube 1 and metal pipe expanding mouth 1-1 are integrally formed.
On the basis of above scheme, the flange seat 3 and flange edge of a knife 3-1 is integrally formed.
On the basis of above scheme, the flange edge of a knife 3-1 diameter is less than metal pipe expanding mouth 1-1 end diameter.
On the basis of above scheme, the flange seat 3 is fixed on by way of welding or screw fastening to be evacuated
On container.
Flange seat in actual use, is first passed through weldering by vacuum all-metal quick locking sealing device provided by the utility model
It connects or screw is anchored on and is evacuated on container, the device for being connected with metal tube is then passed through into nut fast-holding in flange seat
On, start to complete to vacuumize process.
Vacuum all-metal quick locking sealing device provided by the utility model has the advantage that compared with prior art
Vacuum all-metal quick locking sealing device provided by the utility model, it is reasonable in design, in use,
Practical, compact-sized, manufacturing cost is low, especially can be applied to the Fast Installation of batch production device, greatly improves
Working efficiency has wide range of applications, and existing bonding in vacuum can be overcome cumbersome, and the defect of mounting tool low efficiency solves production
Device Fast Installation and reliable vacuum sealing problem.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference:
12 nut of metal tube 1-1 metal pipe expanding mouth, the 3 flange seat 3-1 flange edge of a knife
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As shown in Figure 1, a kind of vacuum all-metal quick locking sealing device, it includes: metal tube 1, metal pipe expanding mouth 1-
1, nut 2, flange seat 3 and flange edge of a knife 3-1；Metal tube 1 and metal pipe expanding mouth 1-1 processing are integral, flange seat 3 and flange knife
Mouth 3-1 processing is integral, is crimped together metal pipe expanding mouth 1-1 and flange edge of a knife 3-1 locking by nut 2, realizes metal
Pipe 1 and the all-metal fast sealing of flange seat 3 under vacuum conditions；
Above-described vacuum all-metal quick locking sealing device, metal pipe expanding mouth 1-1 pass through nut 2 for the flange edge of a knife
Vacuum sealing is realized in 3-1 connection under vacuum conditions.
Above-described vacuum all-metal quick locking sealing device, metal tube 1 are compressed simultaneously by nut 2 and flange seat 3
Realize bonding in vacuum.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
