Technical Field

[0001] The utility model belongs to the technical field of valve manufacturing, and particularly relates to a pipeline pressure regulating anti-theft ball valve. Background Art

[0002] In traditional water supply systems, pipeline valves play a crucial role. They not only control the on-off of water flow but also directly affect the operation efficiency and safety of the system. However, with the acceleration of urbanization and the increasing improvement of infrastructure, the challenges faced by water supply systems are also increasing.

[0003] After retrieval, the publication number is CN208474623U, and the name is a lockable anti-theft ball valve, which includes a valve body, a valve cover, a valve seat, and a spherical valve core. Through research and analysis, it is found that although the anti-theft function is relatively high and can achieve a real anti-theft effect, there are still the following disadvantages to a certain extent.

[0004] For example, the ball valve does not have the functions of pressure regulation and filtration. This makes it difficult to ensure the purity of water quality and the stability of water flow in a complex and changeable water supply environment, thus affecting the user's water use experience. To solve the above technical problems, it is necessary to design a pipeline pressure regulating anti-theft ball valve to solve the above problems. Summary of the Utility Model

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, this pipeline pressure regulating anti-theft ball valve includes a valve body 1. A valve cap 2 is threadedly connected to the top of the valve body 1. A tail cap 3 is threadedly connected to the bottom of the valve body 1. An adjusting cap 4 is arranged in the inner cavity of the valve cap 2. An adjusting spring 5 is sleeved at the bottom of the adjusting cap 4. The bottom of the adjusting spring 5 is connected through a spool 6. The bottom of the spool 6 contacts a filter screen 7. A gasket 8 is arranged at the bottom of the filter screen 7. A sealing cap 9 is arranged at the bottom of the gasket 8. A return spring 10 is sleeved at the bottom of the sealing cap 9. The return spring 10 is fixedly connected to the inner wall of the tail cap 3. A theft-proof body 11 is connected to the left side of the top of the valve body 1. A theft-proof handle 12 is sleeved on the top of the theft-proof body 11. A sphere 13 is arranged in the inner cavity of the valve body 1. A valve stem 14 penetrates through the top of the sphere 13.

[0022] During actual manufacturing, a key shell 15 is sleeved on the surface of the theft-proof handle 12. A first magnet 16 is inlaid on the inner wall of the key shell 15. A connecting spring 17 is fixedly connected to the inner wall of the theft-proof body 11. A second magnet 18 is fixedly connected to one side of the connecting spring 17. A clamping hole 19 for cooperating with the second magnet 18 is opened on the surface of the theft-proof handle 12.

[0023] During actual manufacturing, sealing seats 20 are arranged on both sides of the sphere 13. One side of the sealing seat 20 is fixedly connected to the valve body 1. The top of the theft-proof handle 12 is connected to the valve stem 14 through a flat head screw. A protective cover is inlaid on the top of the theft-proof handle 12.

[0024] During actual manufacturing, a sealing ring 21 is sleeved on the surface of the spool 6. A plug cap 22 is threadedly sleeved on the right side of the top of the valve body 1.

[0025] During actual manufacturing, a dust-proof cap 23 is sleeved on the top of the valve cap 2. A first threaded rod 24 penetrates through the top of the dust-proof cap 23. The bottom of the first threaded rod 24 penetrates to the bottom of the adjusting cap 4. The first threaded rod 24 is threadedly connected to the adjusting cap 4.

[0026] During actual manufacturing, a filter barrel 25 is arranged on the left side of the filter screen 7. A second threaded rod 26 penetrates through the top of the valve body 1. The bottom of the second threaded rod 26 penetrates to the inner cavity of the valve body 1. A brush plate 27 is threadedly sleeved on the surface of the second threaded rod 26.
