[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 its V-type ball core and the metal valve seat with hard alloy surfacing, which 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 to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline.

[0003] During use, water flow in most existing ball valves will leave some dirt and scale inside the valve body. After installation, it is not convenient to disassemble the ball valve to clean the inside. If it is not cleaned for a long time, the quality of the water used may be affected. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 , a technical solution provided by the utility model:

[0019] Embodiment 1:

[0020] In this embodiment, a ball valve that is easy to clean scale includes a valve body 1, one side of the valve body 1 is fixedly connected to a connecting seat 2, the interior of the connecting seat 2 is hollow, a sleeve 6 is provided inside the connecting seat 2, one side of the sleeve 6 is fixedly connected to a cover plate 3, and one side of the cover plate 3 is fixedly connected to a handle 8.

[0021] In this embodiment, the top and bottom sides of the connecting seat 2 are fixedly connected to a fixed plate 10, one side of the fixed plate 10 is rotatably connected to a linkage rod 11, the top end of the linkage rod 11 is rotatably connected to a pressure rod 4, the lower end of the pressure rod 4 is fixedly connected to a moving rod 12, and the bottom end of the moving rod 12 is rotatably connected to the other side of the fixed plate 10.

[0022] In this embodiment, the top end of the linkage rod 11 is also rotatably connected to a movable plate 7 , and a fixing screw 9 is threadedly connected to the movable plate 7 . The bottom end of the fixing screw 9 penetrates the cover plate 3 and extends to the inside of the cover plate 3 .

[0023] When in use, first install the valve body 1 where it is needed, and then install the sleeve 6 inside the valve body 1. During installation, one end of the sleeve 6 needs to be aligned with the opening of the connecting seat 2 and inserted inward. When the sleeve 6 is moved and inserted to the extreme position, the cover plate 6 closes the opening of the connecting seat 2, and then the pressure rod 4 is pressed downward. After the pressure rod 4 is subjected to force, it rotates through the linkage rod 11 and the moving rod 12 to drive the movable plate 7 to rotate downward. When the movable plate 7 rotates to a parallel position, use the fixing screws 9 to fix the movable plate 7 and the cover plate 3 together.

[0024] Embodiment 2:

[0025] In this embodiment, a rubber ring 5 is provided on the outer wall of the sleeve 6 , and the rubber ring 5 is provided at the sleeve connection with the valve body 1 .

[0026] In this embodiment, the outer ring size of the rubber ring 5 is the same as the inner wall size of the valve body 1 .

[0027] After installing the sleeve 6, you can start using the valve body 1. The inner wall of the valve body 1 is covered by the sleeve 6. The water flow will not directly contact the inner wall of the valve body 1 but will flow through the inside of the sleeve 6. Dirt and scale generated after long-term use will remain on the inner wall of the sleeve 6. The user can close the valve body 1 and remove the sleeve 6 for cleaning and replacement. After cleaning, it can be installed according to the above method for repeated use.

[0028] Working principle: When in use, first install the valve body 1 where it is needed, and then install the sleeve 6 inside the valve body 1. When installing, one end of the sleeve 6 needs to be aligned with the opening of the connecting seat 2 and inserted inward. When the sleeve 6 is moved and inserted to the extreme position, the cover plate 6 closes the opening of the connecting seat 2, and then the pressure rod 4 is pressed downward. After the pressure rod 4 is subjected to force, it rotates through the linkage rod 11 and the moving rod 12 to drive the movable plate 7 to rotate downward. When the movable plate 7 rotates to a parallel position, the movable plate 7 and the cover plate 3 are fixed together with the fixing screws 9; after installing the sleeve 6, the valve body 1 can be used. The inner wall of the valve body 1 is covered by the sleeve 6. The water flow will not directly contact the inner wall of the valve body 1 but circulates through the inside of the sleeve 6. The dirt and scale generated after long-term use will remain on the inner wall of the sleeve 6. The user can close the valve body 1 and disassemble the sleeve 6 for cleaning and replacement. After cleaning, it can be installed according to the above method for repeated use.
