Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve which is easy to assemble. Background Art

[0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between the V-type ball core and the metal valve seat with hard alloy surfacing. It is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the drive mode.

[0003] The prior art, such as the utility model with publication number CN205605869U, is an improved ball valve, comprising a valve body, a ball, and a rotating shaft, characterized in that the valve body consists of two parts, with a hollow cylinder in the middle, the two parts are connected at two joints and fixed with screws, the screws are covered with washers, one of the joints is arranged at one end away from the ball, and the other joint is arranged at the other end away from the ball, and the joints are sealed with high-temperature resistant sealing rings. The utility model divides the valve body into two parts, and arranges the two joints at both ends away from the ball, so as to achieve a good sealing effect, extend the maintenance cycle of the ball valve, and solve the problem that the valve body of a general ball valve consists of two parts, which are separated along the diameter direction of the ball, because the opening and closing of the valve will cause wear at the joint, resulting in an unsatisfactory sealing effect at the joint, especially when connected to a high-temperature gas pipeline, regular maintenance is required.

[0004] The inventor found in his daily work that when installing the existing ball valve, it is mainly installed through the flanges and pipelines fixed at both ends of the ball valve. However, in the actual installation process, due to different pipeline layouts, there may be a certain degree of deviation or inaccuracy. The pipeline is too short to be installed with the flange, and there is a certain deviation between the position of the pipeline and the flange, which cannot be aligned, resulting in inconvenience in overall assembly. As a result, the flanges at both ends of the ball valve body cannot be adjusted and cannot adapt to different scenarios, resulting in inconvenience in installation. Utility Model Content

[0023] The specific setting and function of the regulating device 4 will be described in detail below.

[0024] Specifically, the adjusting device 4 includes an extension tube 48, and there are two extension tubes 48. The two extension tubes 48 are respectively slidably connected to the inner walls at both ends of the ball valve body 1, and one end of the extension tube 48 is fixedly connected to a hose 47, and one end of the hose 47 is fixedly connected to the surface of the flange end 3.

At the same time, the adjustment component 2 44 can adjust the slider 42 to move, and the slider 42 drives the flange end 3 to be fine-tuned up and down, and the hose 47 is deformed, so as to facilitate precise installation.

[0026] Specifically, the adjustment component 43 includes a threaded sleeve 431, which is rotatably connected to the surface of the slider 42. A threaded rod 432 is fixedly connected to the side of the flange end 3 close to the threaded sleeve 431. The threaded rod 432 is threadedly connected to the inner wall of the threaded sleeve 431. By rotating the threaded sleeve 431, the threaded sleeve 431 cooperates with the threaded rod 432 to control the slide rod 46 to move in the hollow rod 45, thereby driving the flange end 3 and the extension tube 48 and the hose 47 to move, thereby improving the overall stability.
