[0027] The ball valve body 2 is of the model Q41F-16P, has flanges fixedly connected at both ends, and has the working principle that if the ball hole in the ball body 21 is consistent with the flow direction, the valve is open, and when the ball body 21 is rotated by 90 degrees by the rotating handle 23, the valve is closed. The main function of the ball valve is to start, stop or adjust the flow of the internal medium between the separated chambers, pipes and pipelines, the installation assembly 1 of the utility model is installed between the water inlet and outlet end of the ball valve and the flange connection end, and since the ball valve is a mature prior art, the utility model will not be described in detail.

[0028] Wherein, since the fixed bend block 1422 is fixedly connected with the spring column 1423, and the spring column 1423 is fixedly connected with the swing bar 142, therefore, when the ball valve body 2 is located inside the installation assembly 1, the extension of the fixed bend block 1422 can firmly fix the ball valve body 2 in the installation assembly 1.

[0029] Wherein, since the centers of the first installation slot 111 and the second installation slot 112 are located on the same straight line, therefore, when the hole in the flange plate of the ball valve body 2 and the first installation slot 111 and the second installation slot 112 are located on the same straight line, the user can more quickly and precisely flange-connect the ball valve body 2 with the external device.

[0030] Wherein, since all the components in the ball valve are fixed except the swing assembly 14 and the pressing assembly 13, therefore, the user only needs to simply operate to complete the precise butt joint of the ball valve body 2 and the external device.

[0031] The working principle of the ball valve is described as follows: the mechanical structures in the ball valve are all fixed by threads, and the bolt connections are appropriately hidden in the drawings to make the professional technical features more intuitive. When the ball valve is used, the user needs to place the ball valve body 2 in the fixed strip 122, and then rotate the external flange to be flange-connected with the ball valve body 2 to be attached to the flange plate of the ball valve body 2. At this time, the user rotates the ball valve body 2, and when the first installation slot 111, the second installation slot 112, the flange hole on the ball valve body 2, and the flange hole of the external flange are located on the same straight line, the user rotates the turntable 132 to move the attachment ring 134 towards the position of the external flange, until the attachment ring 134 firmly attaches the external flange to the flange plate of the ball valve body 2. Then the user swings the swing bar 142, which will rotate on the rotating shaft 124 through the support cylinder 141 until the attachment plate 144 and the bottom of the fixed strip 122 are attached together, and then the fixed shaft 143 is fixed by bolts. At this time, the spring column 1423 with the fixed bend block 1422 extends and abuts against the ball valve body 2 to firmly fix the ball valve body 2 between the fixed strip 122 and the swing bar 142. Then the user only needs to precisely flange-connect the ball valve body 2 and the external device by bolts to facilitate the flange installation of the ball valve, which greatly improves the practicability of the ball valve.

[0032] The technical features of the above embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
