Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and more specifically, to a ball valve with high-efficiency protection function. Background Technology

[0002] A ball valve is a valve in which the opening and closing element is driven by the valve stem and rotates around the axis of the ball valve. The ball valve is operated by a handle on the outer wall of the valve stem, which causes the ball inside the valve body to rotate, thereby realizing the opening and closing of the fluid.

[0003] The stem and handle of a ball valve are both exposed to the outside. If the ball valve is installed outdoors, the stem and handle are prone to corrosion and damage, affecting the normal rotation of the stem and handle in the future. Utility Model Content

[0021] Please see Figures 1-5 A ball valve with high-efficiency protection function includes a ball valve body 1. A protective tube 2 is detachably installed on the outside of the ball valve body 1. The protective tube 2 is sleeved on the outside of the valve stem of the ball valve body 1. A square post 3 is fixedly connected to the top of the valve stem. A protective plate 4 is fixedly connected to the top of the valve stem. A square groove 5 is provided at the bottom of the protective plate 4. The square post 3 is inserted into the square groove 5. A sliding groove 6 is provided at the side of the square groove 5. A sliding seat 7 is slidably arranged inside the sliding groove 6. A locking post 8 is fixedly connected to the side of the sliding seat 7. A locking groove 9 adapted to the locking post 8 is provided on the square post 3. A pull rod 10 is fixedly connected to the other end of the sliding seat 7. The pull rod 10 slides with the protective plate 4. A compression spring 26 is sleeved on the outside of the pull rod 10. The compression spring 26 is located inside the sliding groove 6. A protective sleeve 11 is fixedly connected to the bottom of the protective plate 4. The protective sleeve 11 is sleeved on the outside of the protective tube 2 and the handle on the ball valve body 1. A pull plate 12 is fixedly connected to one end of the pull rod 10 extending to the outside of the protective plate 4. A pull handle 13 is fixedly connected to the side end of the pull plate 12 to facilitate pulling the pull rod 10. A first sealing gasket 14 that mates with the protective plate 4 is fixedly connected to the side end of the pull plate 12 to ensure the sealing between the pull plate 12 and the protective plate 4. An annular groove 15 is provided on the outside of the protective tube 2. A sealing ring 16 is provided inside the annular groove 15 to improve the sealing between the protective sleeve 11 and the protective tube 2. Multiple slots 17 are evenly fixed on the outside of the protective sleeve 11 to facilitate inserting iron rods or the like into the slots 17. This facilitates the rotation of the valve stem of the protective sleeve 11, the protective plate 4, the square column 3, and the ball valve body 1, and facilitates the control of the opening and closing of the ball valve body 1. A rainproof ring 18 is fixedly connected to the outside of the protective sleeve 11 on the upper side of the multiple slots 17 to prevent rainwater from entering the inside of the slots 17.

[0022] Specifically, the protective tube 2 is fitted over the outside of the valve stem of the ball valve body 1. Then, the pull rod 10, slide 7, and locking pin 8 are pulled outwards, covering the outside of the square post 3 with the protective plate 4. The pull rod 10 is then released, and the compression spring 26 pushes the slide 77 and locking pin 8 to move, causing the locking pin 8 to engage inside the locking groove 9. This allows the protective sleeve 11 to be fitted over the protective tube 2, the valve stem of the ball valve body 1, and the handle, thus protecting the valve stem and handle of the ball valve body 1 and preventing them from being exposed. Corrosion damage affects the normal rotation of the valve stem and handle in the later stages. By setting a first sealing gasket 14 on the side of the pull plate 12, the slide 7, pull rod 10 and pull plate 12 are moved by the compression spring 26, so that the pull plate 12 is pressed tightly against the protective plate 4, thereby pressing the first sealing gasket 14 tightly against the protective plate 4. At the same time, by sleeved with a sealing ring 16 on the outside of the protective tube 2, the sealing between the protective sleeve 11 and the protective tube 2 is ensured, thereby ensuring that the protective tube 2, the protective sleeve 11 and the protective plate 4 are in a closed space, which improves the effectiveness of the ball valve body 1.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The ball valve body 1 is fitted with a first connecting seat 19 and a second connecting seat 20. The second connecting seat 20 is fixedly connected to the first connecting seat 19 by a plurality of fixing screws 21. The top end of the first connecting seat 19 and the bottom end of the second connecting seat 20 are both provided with connecting grooves 22 that are adapted to the ball valve body 1. A second sealing gasket 23 is provided between the first connecting seat 19 and the second connecting seat 20. The second sealing gasket 23 ensures the sealing of the connection between the first connecting seat 19 and the second connecting seat 20 and prevents water from contacting the fixing screws 21. The protective tube 2 is fixedly connected to the second connecting seat 20 for easy disassembly and assembly. The bottom end of the first connecting seat 19 is provided with countersunk grooves 24 at the positions corresponding to the plurality of fixing screws 21. The plurality of fixing screws 21 are respectively located inside the plurality of countersunk grooves 24. Sealing caps 25 are inserted into the plurality of countersunk grooves 24 to seal the fixing screws 21 and prevent the fixing screws 21 from being exposed.

[0024] Specifically, since the first connecting seat 19 and the second connecting seat 20 are fixedly connected to the outside of the ball valve body 1 by multiple fixing screws 21, the first connecting seat 19 and the second connecting seat 20 play a protective role for the ball valve body 1, and at the same time facilitate the disassembly and assembly of the first connecting seat 19 and the second connecting seat 20. People can selectively install this protective structure according to their usage needs.

[0025] In summary, when using the overall equipment: The first connecting seat 19 and the second connecting seat 20 are fitted onto the outside of the ball valve body 1, and are fixedly connected together by multiple fixing screws 21. Then, the sealing cap 25 is inserted into the countersunk groove 24. Since the first connecting seat 19 and the second connecting seat 20 are fixedly connected and fitted onto the outside of the ball valve body 1 by multiple fixing screws 21, they provide protection for the ball valve body 1 and facilitate disassembly and assembly of the first connecting seat 19 and the second connecting seat 20 according to usage requirements. The protective structure can be selectively installed. When it is necessary to rotate the valve stem and handle of the ball valve body 1, a rod-shaped tool such as an iron rod can be inserted into the slot 17, and then the protective sleeve 11 can be rotated. The protective sleeve 11 drives the protective plate 4, the square column 3 and the valve stem to rotate, thereby facilitating the control of the opening and closing of the ball valve body 1. When it is necessary to rotate the handle on the ball valve body 1, the handle 13, the pull rod 10, the slide 7 and the locking pin 8 are pulled to move, so that the locking pin 8 separates from the locking groove 9, the protective plate 4 and the protective sleeve 11 can be removed, and then the handle and valve stem of the ball valve body 1 can be rotated.

[0026] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
