Embodiment
Here is that the utility model is further illustrated in conjunction with the accompanying drawings and embodiments.
Reference picture 1, a kind of liquefied gas ready-packaged joint self-locking device, including spring 1 and from lock tube 2.
Wherein, interconnected heavy caliber endoporus 3 and small-bore endoporus 4 are included from the endoporus of lock tube 2, as shown in Fig. 2 greatly
The diameter of bore endoporus 3 is adapted with the external diameter of ready-packaged joint 5（The diameter of heavy caliber endoporus 3 is slightly larger than the external diameter of ready-packaged joint 5 most
General goal is the external diameter at automatic locking wrench 8）, such ready-packaged joint 5 may be mounted in heavy caliber endoporus 3.Small-bore endoporus 4 it is straight
Footpath is adapted with the external diameter of pipeline 6, and pipeline 6 may pass through small-bore endoporus 4 and is connected with ready-packaged joint 5.Installed using on pipeline
Good ready-packaged joint 5 blocks anti-dropout part, avoids coming off from lock tube 2.
The internal diameter of spring 1 is adapted with the diameter of small-bore endoporus 4, and the external diameter of spring 1 is less than the external diameter from lock tube 2,
It one end of spring is in contact with the end face of the small-bore endoporus 4 from lock tube 2, prevent spring 1 from entering in small-bore
In hole 4, make it to producing elastic force from lock tube 2.The internal diameter of spring 1 is adapted with the external diameter of pipeline 6, and such spring 1 can be set in
The outer surface of pipeline 6.It can be given by spring 1 from lock tube 2 and elastic force is provided, it is ensured that the self-locking of ready-packaged joint 5 is enclosed on from the moment of lock tube 2
On spanner, ready-packaged joint 5 caused by the failure of its auto-lock function is avoided to come off.
A kind of liquefied gas ready-packaged joint self-locking system, include the pipeline 6 and ready-packaged joint 5 of interconnection.Wherein, in pipeline
6 are provided with valve 7, and spring 1 is set in valve 7 and from the pipeline 6 between lock tube 2, at this moment the both ends of spring 1 respectively with valve
7 and the end face of the small-bore endoporus 4 from lock tube 2 be in contact, one end of pipeline 6 is movably arranged on the small-bore endoporus 4 from lock tube 2
It is interior.It is corresponding with the length of ready-packaged joint 5 from the length of lock tube 2.When filling Liquefied gas tanker, hold from lock tube 2, make its compression
Spring 1 all exposes close to valve 7, ready-packaged joint 5, opens automatic locking wrench 8, ready-packaged joint 5 is filled on mouth installed in tank car,
Automatic locking wrench 8 is closed, unclamps from lock tube 2, is so enclosed on the self-locking of ready-packaged joint 5 under the elastic force effect of spring 1 from lock tube 2
On spanner 8, start to fill work.
In addition, ready-packaged joint 5 and automatic locking wrench 8 are movably arranged on from the heavy caliber endoporus 3 of lock tube 2, so work as self-locking
When set 2 is enclosed on 5 outside of ready-packaged joint, automatic locking wrench 8 can be compressed, so as to prevent the auto-lock function of automatic locking wrench 8 from failing,
Ensure safe and reliable.
