[0029] In the technical solution of the utility model, the connecting tube can fix the closing tube 7 and the mounting tube 4, and the setting of the fixing tube can install the second main tube 3, and the spring 5 on the mounting tube 4 can extend and retract the ball 6, and the inner tube 10 on the first main tube 2 can push the plate 9 to move when entering the inner wall of the closing tube 7, and the plate 9 can push the ball 6, so that when the first main tube 2 is replaced and repaired, when the first main tube 2 withdraws from the closing tube 7, the ball 6 can seal the closing tube 7 with the cooperation of the spring 5, so that the staff can speed up the maintenance of the first pipeline without closing the valve.

[0030] In addition, the outer wall of the sphere 6 is made of rubber material to further provide a seal, and the spring 5 is made of stainless steel material to ensure the service life of the spring 5.

[0031] In the technical solution of the utility model, if Figure 1-Figure 3 As shown, the upper end of the connecting tube 1 is slidably connected with a locking cylinder 12, and the locking cylinder 12 is rotatably installed with the outer wall of the closing tube 7. The inner wall of the locking cylinder 12 is threadedly connected with the outer wall of the first main tube 2. The closing tube 7 can provide rotational support for the locking cylinder 12, and the locking cylinder 12 can be threadedly connected to the first main tube 2 to lock the first main tube 2.

[0032] In the technical solution of the utility model, if Figure 2 As shown, a placement groove is provided on the outer wall of the installation pipe 4 , and a sealing ring 11 is sleeved on the outer wall of the installation pipe 4 inside the placement groove. The sealing ring 11 can seal the installation pipe 4 and the second main pipe 3 .

[0033] In the technical solution of the utility model, if Figure 2 and Figure 3As shown, the height of the closing tube 7 is higher than the connecting tube 1, and the height above the sliding groove 8 corresponds to the upper side position of the connecting tube 1. By making the height of the closing tube 7 higher than the connecting tube 1 and the height above the sliding groove 8 corresponding to the upper side position of the connecting tube 1, it is convenient for the inner tube 10 to enter the interior of the closing tube 7 and play a sealing role.

[0034] When in use, first, the main components of the connecting device include the connecting tube 1, the mounting tube 4, the second main tube 3, the spring 5, the ball 6, the closing tube 7, the abutment plate 9, the inner tube 10 and the first main tube 2. The mounting tube 4 is fixed on the inner wall below the connecting tube 1. The second main tube 3 is installed on the outer wall of the mounting tube 4 through threads. The spring 5 is installed on the upper end of the mounting tube 4. The ball 6 is placed above the spring 5 and is subjected to the elastic force of the spring 5. The closing tube 7 is fixed on the inner wall above the connecting tube 1. The lower side surface thereof is a curved surface design, which fits tightly with the outer wall of the ball 6. When the ball 6 is subjected to the upward thrust from the spring 5, it will be tightly pressed on the lower curved surface of the closing tube 7, thereby closing the passage between the closing tube 7 and the connecting tube 1.

[0035] A sliding groove 8 is designed inside the closing tube 7, and the abutment plate 9 is slidably installed inside the sliding groove 8. The other side of the inner tube 10 is fixedly connected to the first main tube 2. When the first main tube 2 needs to be connected, the inner tube 10 can be pushed to make the abutment plate 9 slide in the sliding groove 8, thereby compressing the ball 6 to make it leave the lower curved surface of the closing tube 7. In this way, the channel between the closing tube 7 and the connecting tube 1 is opened, allowing fluid or gas to pass through;

[0036] In addition, a sealing ring 11 is sleeved in the placement groove on the outer wall of the installation tube 4, which increases the sealing between the installation tube 4 and the second main tube 3 and prevents leakage of fluid or gas. In order to fix the first main tube 2, a locking cylinder 12 is also slidably connected to the upper end of the connecting tube 1. The locking cylinder 12 is rotatably installed with the outer wall of the closing tube 7. When the first main tube 2 is pushed into the connecting tube 1, the first main tube 2 can be firmly locked on the connecting device by rotating the locking cylinder 12 and utilizing the threaded connection between the locking cylinder 12 and the outer wall of the first main tube 2. The outer wall of the ball 6 is made of rubber, which not only ensures that the ball 6 is tightly fitted with the lower curved surface of the closing tube 7, but also allows the ball 6 to deform when subjected to pressure, thereby smoothly opening the channel. The spring 5 is made of stainless steel, which ensures that it has good elasticity and corrosion resistance and can work stably for a long time.

[0037] The pipeline connecting device realizes fast and reliable connection and disconnection of the pipeline through the coordinated action of components such as the spring 5, the ball 6 and the abutment plate 9, thereby facilitating the staff to repair and replace the pipeline on the rear side of each group of connecting devices without closing the valve. At the same time, the sealing ring 11 and the locking cylinder 12 and other components ensure the sealing and stability of the connection.
