[0030] In one possible embodiment, the ball valve 2 has a push plate 9 on the inside, which is movably arranged inside the ball valve 2. One side of the push plate 9 has a compression spring, which is installed between the push plate 9 and the mounting frame 6. The outside of the push plate 9 has a push rod 10, which is fixed to the outer surface of the push plate 9.

[0031] In the present invention, the push plate 9 can be used to enable the liquid to push the push plate 9 to move after the ball valve 2 is opened, thereby controlling the push plate 9.

[0032] In one possible embodiment, the outer side of the top rod 10 has a buckle 11, which is fixed to the outer surface of the top rod 10. The outer side of the buckle 11 has an insertion rod 14, which is movably arranged inside the mounting frame 6. The outer side of the insertion rod 14 has a support spring 15, which is located inside the mounting frame 6 to support the insertion rod 14.

[0033] In the present invention, the buckle 11 can be used to facilitate the change in the position of the insertion rod 14 , so that the position of the insertion rod 14 can be controlled by the movement of the push plate 9 .

[0040] Working principle: When in use, the cock 3 is installed on the inner side of the mounting frame 6, and then the mounting head 7 is used to form a snap connection with the mounting frame 6 to fix the cock 3. Then the pressure gauge 4 is used for monitoring. After the ball valve 2 is opened, the internal liquid pushes the push plate 9, causing the push plate 9 to compress the compression spring. The top rod 10 is used to push the buckle 11 so that the buckle 11 pushes the insertion rod 14 into the mounting head 7, thereby forming a limit for the mounting head 7.
