The vacuum degree measuring device can be conveniently and rapidly connected between a vacuum tester or a vacuum unit and the multifunctional safety explosion-proof plug, the vacuum tester is used for directly measuring the vacuum degree of the low-temperature gas cylinder interlayer, and the detection value is real and accurate. If the vacuum degree does not meet the design requirement, the vacuum unit can be connected immediately, and the vacuum unit is directly vacuumized to meet the requirement. The vacuum degree detection device has the advantages of reasonable structural design, safety, convenience and quickness in use and the like, and is suitable for quality inspection departments of low-temperature gas cylinders to detect the vacuum degree of the interlayer of the low-temperature gas cylinder. However, such a test connector can only be used with one kind of interface, and cannot satisfy the connection of multiple test connectors or test instruments.
Therefore, there is a need for a vacuum fitting that can be quickly replaced and replaced that reduces the disadvantages of the prior art devices.
SUMMERY OF THE UTILITY MODEL

3. The utility model discloses reduce the installation quantity of different vacuum measuring instrument on the equipment, reduced capital investment and fund and occupied the pressure, improved the performance of enterprises.
Drawings
Fig. 1 is a schematic view of the installation of the conversion device of the present invention;
wherein: 1-vacuum equipment, 2-vacuum measuring points, 3-GU type high vacuum ball valves, 4-spigot and socket phi 20 type interfaces and 5-KF16 type interfaces.
Detailed Description
The present invention will be further described, but not limited to, by the following examples in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1, the present embodiment provides a conversion device for a vacuum interface, which includes a GU-type high vacuum ball valve, a socket type phi 20 interface, and a KF16 interface, which are connected in sequence; wherein, GU type high vacuum ball valve welds on vacuum measurement point of vacuum apparatus, and the pipe diameter of KF16 type interface is 15.5 mm.
The KF16 type interface is in plug-in connection with the socket phi 20 type interface, and the KF16 type interface and the socket phi 20 type interface are both provided with sealing rings. After the KF16 type interface is inserted into the phi 20 type interface, the vacuum detection is not influenced because the inside of the interface is provided with the standard sealing ring. The spigot-and-socket phi 20 type interface is connected with the GU type high vacuum ball valve through a flange.
In this embodiment, the pipe diameter 15.5mm of the KF16 type interface is the size after transformation, and can not be changed, because these two interfaces are general equipment, and are more representative, and other joints are less numerous. Relatively speaking, the method has high universality and economy.
When in use, the requirement of the vacuum degree is 1.0 x 105-1.0*103In the range of Pa, firstly closing the GU16 type high vacuum ball valve 3, and directly installing a ZJ-2Y type metal direct insertion type vacuum gauge on the welding socket phi 20 type interface 4;
the requirement for vacuum degree is 1.0 x 103-1.0*102In the range of Pa, firstly closing the GU16 type high vacuum ball valve 3, and directly installing a ZJ-52T type metal direct insertion type vacuum gauge on the welding socket phi 20 type interface 4;
the requirement for vacuum degree is 1.0 x 102-1.0*10-2In the Pa range, the GU16 type high vacuum ball valve 3 can be closed first, and a KF16 joint 5 with the pipe diameter changed to 15.5mm is inserted into the welding socket phi 20 type interface, so that the joint is converted to mount the capacitance film vacuum gauge.
According to the technical scheme, only one vacuum measuring point needs to be reserved on the equipment, so that the number of the vacuum measuring points is greatly reduced, air leakage is avoided, and the vacuum environment in the vacuum equipment is guaranteed to the greatest extent. The conversion device is welded on a vacuum measurement point, and the conversion device can be used for realizing rapid switching of vacuum measurement instruments with different specifications.
